A brief idea

Over the years, various devices designed for people with special needs have been used for a while and then replaced with modern devices to make everyday life easier. The development of mobile devices is especially improved today and through them different everyday activities are facilitated, not only by people with special needs. The purpose of this paper is to present some of the modern mobile devices with an analysis of their operating systems, functionalities, applications and design. Based on the research, their usability for both sighted and visually and hearing-impaired users is described. Attention is paid to the preferences formed among users when using specialized applications developed for mobile devices. Based on a survey of specific target user groups, the paper provides summary results to support the thesis on the importance of the facilities, offered by modern mobile devices.

One of the main directions of information systems development is to increase the efficiency of collecting, processing and exchanging information through the introduction of modern data transfer technologies, automated remote monitoring and control. The cornerstone of this concept is mobile devices that solve the issue of operational data exchange and processing. Modern mobile services used including the exchange and processing of personalized, banking and critical data are the result of the steady increase in the number of crimes in the field of information security in relation to and using mobile devices. The widespread use of these devices for access to protected information contained in information systems has given special importance to the issue of information security.The subject of this research is to assess the current state of information security mechanisms for mobile operating systems that form the basis of the structure of episodic distributed mobile networks. The Android OS (operating system) was used as an example. The article discusses the problems of the development of a mobile ecosystem and methods aimed at solving them, the main vectors of malicious impact, ways of countering the means of static and dynamic analysis and modern protection mechanisms.

Evaluation of software reliability is an important part of the process of developing modern software. Many studies are aimed at improving models for measuring and predicting the reliability of software products. However, little attention is paid to approaches to comparing existing systems in terms of software reliability. Despite the enormous importance for practice (and for managing software development), a complete and proven comparison methodology does not exist. In this article, we propose a software reliability comparison methodology in which software reliability growth models are widely used. The proposed methodology has the following features: it provides certain level of flexibility and abstraction while keeping objectivity, i.e. providing measurable comparison criteria. Also, given the comparison methodology with a set of SRGMs and evaluation criteria it becomes much easier to disseminate information about reliability of wide range of software systems. The methodology was evaluated on the example of three mobile operating systems with open source: Sailfish, Tizen, CyanogenMod. A byproduct of our study is a comparison of the three analyzed Open Source mobile operating systems. The goal of this research is to determine which OS is stronger in terms of reliability. To this end we have performed a GQM analysis and we have identified 3 questions and 8 metrics. Considering the comparison of metrics, it appears that Sailfish is in most case the best performing OS. However, it is also the OS that performs the worst in most cases. On the contrary, Tizen scores the best in 3 cases out of 8, but the worst only in one case out of 8.

Smartphone users' satisfaction is related to several factors of interaction that represent criteria evaluated in the choice of the operating system. This paper investigates the usage satisfaction of Android, iOS and Windows Phone mobile operating systems users' and deals with multicriteria decision making. A survey was applied and 314 answers were obtained. The evaluated criteria and the scores obtained through the survey were the initial parameters for the multicriteria decision-making method TOPSIS. The method classified the three alternatives based on preferences over screen, terminology, learning and system capabilities. The iOS was the best classied in the proposed evaluations. Android got the second place in the Screen factors. In the others, Windows Phone was second and Android was third. A small variation in the weights did not change the order of classification found. Although ranking should reflect the decision makers preference, further investigations can be carried out using the TOPSIS method and its relationship to mobile devices interface.

The recommendation system recognizes important facts from a plurality of indicators, captures the similarity of the facts, makes conclusions using induction, analogy, deduction and evaluates the results of its work. The algorithm of the advisory system is to optimize the excursion route by means of spaceoriented technologies. The authors carried out a typological division of excursions, among which a tour, which includes only those excursion objects that are suitable for the season, multi-city tour of historical and modern direction, which provides an overview of historical and cultural monuments, buildings and structures, natural objects , places of famous events, elements of city improvement, industrial and agricultural productions, memorable places connected with historical events in the life of our people, development of society and state, review of buildings and structures, memorial sites monuments related to the life and activity of prominent personalities, works of architecture and urban planning, buildings: residential, public, industrial enterprises, cultural objects, engineering structures (fortresses, bridges, towers), mausoleums and other buildings, such as forests, groves, parks, rivers, lakes, ponds, reserves, sanctuaries, individual trees, relict plants, viewing of expositions of state and national museums, art galleries, permanent and temporary exhibitions.

This work aims at analysing the EU Commission’s decision Google Android of 18 July 2018. Rather than focusing on the deterring effect of the fine, we question both the underlying damage theory and the potential effects of associated remedies, especially with regard to Android’s two-sided structure. Not only is this structure the keystone of Google’s business model, but also that of Android’s very technical architecture. Such a market structure induces specificities in terms of value creation and stakeholders’ interdependence which urges to consider Google’s practices (anti-fragmentation provisions and apps’ pre-installation) under these two dimensions.; Ce travail porte sur la décision de la Commission européenne du 18 juillet 2018 dans l’affaire Google Android. Il ne traite pas des effets incitatifs de l’amende mais s’interroge sur la théorie du dommage sous-jacente et sur les effets potentiels des injonctions qui en découlent, notamment au regard de la structure biface d’Android. C’est en effet sur cette dernière que se fonde le modèle économique de de Google, mais également l’interface technique d’Android. Il s’agit donc de lire la stratégie de la firme, en termes de pré-installation d’applications et de clauses anti-fragmentation, selon ce double prisme qui introduit des spécificités en termes de création de valeur et d’interdépendance entre acteurs.

Informacijska tehnologija utječe na naš osobni, društveni i javni život te je napravila značajni utjecaj na kvalitetu samog života. Korištenje informacijskih sustava utječe na poboljšanje učinkovitosti i djelotvornosti cijelog niza poslovnih funkcija i procesa na način da omogućuje bolju i kvalitetniju komunikaciju i koordinaciju sa svim zainteresiranim stranama, potom olakšava administraciju, smanjuje distribucijske i komunikacijske troškove, pomaže pri otvaranju na nova i nepoznata tržišta te pruža up – to – date informacije koje su nužne za pravovremeno reagiranje na sve promjene s kojima se susrećemo. Razvoj operacijskih sustava na mobilnim uređajima je aktualan već duže vrijeme, te se zbog njihove složenosti još uvijek razvija. Operacijski sustavi za mobilne uređaje kombiniraju značajke operacijskog sustava osobnog računala sa značajkama koje su potrebne za ručnu, odnosno mobilnu upotrebu. U današnjem vremenu ljudi najviše koriste Android operacijski sustav koji je popularniji i od Windows operacijskog sustava koji se koristi na računalima. Shodno tome, korisnici na svojim mobilnim uređajima, odnosno čak njih 80,7%, upotrebljavaju Android. No, uz Android tu je još i operacijski sustav IOS, koji mu konkurira. Za potrebe završnog rada opisani su operacijski sustavi te detaljno analizirani i uspoređeni operacijski sustav Android i IOS koji su vodeći na tržištu. Information technology affects our personal, social and public life and has made a significant impact on the quality of life itself. The use of information systems affects the improvement of efficiency and effectiveness of a whole set of business functions and processes in a way that enables better quality of communication and coordination with all stakeholders, it also facilitates administration, reduces distribution and communication costs, helps in opening up new and unknown markets, and provides up - to - date information that is necessary for timely reactions to any changes we might face. The development of mobile operating systems has been ongoing for a long time, and because of their complexity, it is still in the process of development. Mobile operating systems combine personal computer operating system features with features that are necessary for manual or mobile use. Today, the most used operating system is Android, it is even more popular than the Windows operating system that is used on computers. Accordingly, up to 80.7% of mobile users use Android. As for other operating systems there is also the iOS mobile operating system, which is in fact Android's biggest competitor. For the purposes of the final assignment, operational systems are described throughout the paper, with an emphasis on detailed analysis and comparison of the Android and iOS systems, which are the leading operating systems on the market.

Purpose The purpose of this paper is to propose a comprehensive theoretical framework to explain the different diffusion dynamics of a technology realized under an open source (OS) regime vs a technology realized under a closed-proprietary (CP) regime. Design/methodology/approach Following a systematic combining approach, theoretical predictions derived from literature on diffusion of innovation and on open innovation were matched with empirical observations derived from a case study of two mobile operation systems, which were released under different technological regimes. Findings This paper proposes a theoretical framework and a set of original theoretical propositions that can help to explain the differences in the diffusion dynamics of technologies that are released under different regimes (i.e. CP vs OS). Research limitations/implications This paper provides managers a better understanding of the diffusion dynamics of technologies released according to an open innovation strategy. In addition, the empirical case study improves the understanding of an important industry (the MOS industry) that has not been fully investigated from the innovation diffusion perspective. Nevertheless, the efficacy and generalizability of the theoretical framework proposed in this paper require future empirical tests. Originality/value This paper makes an original contribution to the open innovation and innovation diffusion literature by linking, in a conceptual model, three antecedents of the diffusion of a new technology that previous literature has considered only separately: the regime under which the technology is released (OS vs CP), the contingencies related to the characteristics of the technology and to the network of its adopters, and the resulting barriers to adoption.

The number of Internet-connected mobile devices reportedly surpassed the human population in Oct. 2014, proving that such devices are an indispensable part of our daily lives. One might also argue that in the world of business, every business is potentially a “mobile” business. This is not surprising, as the increasing capabilities of mobile devices have paved the way for many new and exciting applications (e.g., mobile commerce and payment). However, due to their popularity and the amount of data that they can store and make accessible, these devices are increasingly being targeted by cybercriminals. This chapter presents background information on the capabilities of mobile devices, the role of mobile devices within an enterprise, mobile operating systems, and finally, mobile security and privacy threats.

The number of smartphones is constantly increasing and they have become a central part of our lives. A big role for their success is the large number of available applications. While these applications open up a lot of opportunities for their users, they can also pose risks. With the amount of available applications, it is inevitable that they also include bad quality software. While these applications may not pose a direct risk to the device itself, many of them are communicating to some kind of back-end server on the internet. Furthermore, "free" applications often include some kind of advertisement, which needs to be loaded from a server again. We analyze the existing ecosystem of third party tracking in web and mobile applications and evaluate defenses according to their effectiveness in blocking tracking efforts. We show that there is still a lot of information transmitted in clear text, without the use of Transport Layer Security. In addition, even when TLS is used, this tracking information can still be used by attackers for certain kind of attacks. Based on our findings, we propose different approaches to protect user privacy and security. Specifically, we explore notary-based validation schemes for certificate validation and provide a longitudinal study of certificate validation capabilities of available notary services. Mobile apps already employ certificate pinning to prevent interception attacks. However, the application still needs to be updated when the corresponding certificate changes. We therefore provide an on-device certificate pinning solution, which utilizes notary services to update pinned certificates automatically and transparently for the user. Finally, we evaluate existing Android malware analysis platforms and provide metrics on the effectiveness and inter-dependencies of these services. This allows security analysts to select the best fitting system or subset of systems to accomplish their analysis task.

Technologies for augmenting reality have been consolidated during the last decades, extending their applicability to more and more socio-economic areas. The rapid evolution of mobile technologies and virtualization of the digital environment have created auspicious conditions for massive extension and implementation of solutions for augmenting reality at global level. Experience has already shown that augmented reality, alongside virtual reality can offer very important support solutions in modeling the real world with the aim of extending the human capabilities of perception, allowing the opening of a new phase in the world’s socio-economic development. Starting from the evident tendencies that have manifested at global level in the development and implementation of augmented reality technologies, the paper begins with the presentation of the most important aspects related to augmented reality technologies, highlighting their main areas of application, and presents the study realized for identifying the level of knowledge, use and effective experimentation of augmented reality applications by mobile device users. The results of this study could be very useful to the socio-economic environment, starting with the field of research, continuing with developers and providers of augmented reality solutions, manufacturers and providers of hardware infrastructure support for augmented reality solutions and systems, final users of these solutions, both individuals and businesses, and experimenting digital communities.

Hiter razvoj mobilne tehnologije, mobilnih omrežij in njenih storitev je prispeval k hitremu razvoju mobilnega poslovanja, ki je trenutno najhitreje rastoči način poslovanja, kateri vključuje izjemen napredek pri razvoju mobilnih omrežij in tehnologij mobilnih naprav, kot so pametni telefoni, tablice itd. Vse to se odraža pri izjemni prodaji mobilnih naprav, ki narašča vsako leto in s tem vse bolj utrjuje svojo vlogo primarnega načina poslovanja v današnjem času. Mobilno poslovanje je v mnogih pogledih bolj uporabno od elektronskega poslovanja, saj sta njeni odločilni prednosti mobilnost naprav in nenehna povezanost preko spleta kadarkoli in kjerkoli se nahajamo. Vse od leta 2007, ko so se začeli uveljavljati in razvijati pametni telefoni, je sledil sočasno izjemen razvoj mobilnih aplikacij, ki vsako leto dosega fenomenalno rast na globalnem tržišču. Danes je uporabnikom na voljo več milijonov mobilnih aplikacij preko različnih spletnih trgovin in njihovo število nenehno raste. Razvijalci in podjetja, ki razvijajo in tržijo svoje mobilne aplikacije preko spletnih trgovin, se celo srečujejo z vse večjimi izzivi. Konkurenca postaja vsako leto vse bolj ostra, večina mobilnih aplikacij uporabniki nikoli ne prenesejo ali uporabijo, le majhen delež razvitih aplikacij je uspešnih, tako v številu prenosov, v njihovi dolgoročni uporabi s strani uporabnikov, v uspešnem trženju in donosnosti. Ugotovili smo, da je mobilno poslovanje postala prevladujoča oblika poslovanja na svetu, zaradi izjemnih prednosti, kot so nenehno opravljanje storitev preko spleta, iskanje in določanje lokacije itd. Razvoj aplikacij za operacijske sisteme se razlikuje, kot se tudi razlikuje način trženja preko različnih spletnih trgovin. Ključni dejavniki uspešnega razvoja mobilnih aplikacij so uporabnost, enostavnost in privlačnost aplikacij. Pomembno je, da aplikacije razvijemo za končne uporabnike, pri tem preučimo njihovo vedenje, potrebe, zahteve in želje ter na tej osnovi razvijemo aplikacije, ki jih bodo pritegnile. Aplikacije bi naj nudile unikatno vrednost, v smislu udobnosti, zabave in koristnosti za uporabnike. Fast development of mobile technology, mobile networks and their services has contributed to fast development of mobile business, which is currently the fastest growing way of doing business, that includes phenomenal progress in development of mobile networks and technologies of mobile devices, such as are Smart phones, Tablets etc. All of that it is reflected by exceptional sales of mobile devices, which are growing every year and with increasing sales their role is becoming strengthened as primary way of doing business in present time. The mobile business is in many points of view more usefull than electronic business, because of two main critical advantages, which are mobility of devices and constantly on-line connection with Internet whenever and whereever we are to be situated. Since 2007, when Smart phones have started to emerge and grow, it has followed simultaneously exceptional development of mobile applications, which is achieving every year phenomenal growth at global market. Today different Apps stores are offering millions of mobile applications for users and their numbers are still growing. Developers and companies, who are developing and marketing their mobile applications, are meeting with even more greater chalenges. The competition is becoming every year keen, most of mobile applications users never download or use, only a small percentage of applications are succesfull by numbers of download, their long-term usage by users, succesful marketing and their profitability. We have discovered, that mobile business has become predominating way of doing business in the world, because of exceptional advantages, such as constantly performing services on-line, finding and positioning location, etc. Development of applications for each operating systems is different, such as there is different way of marketing over several App stores. Key factors for succesfull development of mobile applications are usefullness, simplicity and attractiveness of applications. It is very important that we develop mobile applications for the end users, by examining closely their behavior, needs, requests, desires and that on these basis we develop mobile applications, which will attract users. Apps should offer unique value in sense of convenience, entertainment and usefulness for users.

[EN] Rich-sensor smart phones have made possible the recent birth of the mobile sensing research area as part of ubiquitous sensing which integrates other areas such as wireless sensor networks and web sensing. There are several types of mobile sensing: individual, participatory, opportunistic, crowd, social, etc. The object of sensing can be people-centered or environment-centered. The sensing domain can be home, urban, vehicular Currently there are barriers that limit the social acceptance of mobile sensing systems. Examples of social barriers are privacy concerns, restrictive laws in some countries and the absence of economic incentives that might encourage people to participate in a sensing campaign. Several technical barriers are phone energy savings and the variety of sensors and software for their management. Some existing surveys partially tackle the topic of mobile sensing systems. Published papers theoretically or partially solve the above barriers. We complete the above surveys with new works, review the barriers of mobile sensing systems and propose some ideas for efficiently implementing sensing, fusion, learning, security, privacy and energy saving for any type of mobile sensing system, and propose several realistic research challenges. The main objective is to reduce the learning curve in mobile sensing systems where the complexity is very high., This work has been partially supported by the "Ministerio de Ciencia e Innovacion", through the "Plan Nacional de I+D+i 2008-2011" in the "Subprograma de Proyectos de Investigacion Fundamental", project TEC2011-27516, and by the Polytechnic University of Valencia, through the PAID-05-12 multidisciplinary projects.

[EN] Personal devices are penetrating most technology market sectors nowadays. Despite their growing computation power, they execute powerful yet heavy software platforms that, in the end, expose the physical hardware resource limitations. Such software platforms are becoming thick layers that contain an embedded mobile operating system with graphical tools, communication software supporting wired and wireless protocols, and virtual machines and hosting platforms to enable portable code execution. In the last decade, mobile devices have also become part of some real-time domains that in the past only used specialized computing hardware; this is the case of, for example, industrial control infrastructures where personal devices are used mainly for interfacing purposes. Still, the full adoption of personal embedded devices in real-time environments has not been achieved due to their temporal unpredictability derived, among other reasons, from the operating system's execution and concurrency model. Therefore, mechanisms for efficient and timely management of resources are needed to meet, at least, soft real-time constrains of the emerging application domains that are heavy resource consumers. In this paper, we describe a scheme for integrating resource management techniques on top of the concurrency model of embedded operating systems that use the active object concurrency model; we illustrate the approach by taking, just as example, the model of Symbian. Also, results are presented and discussed that validate the proposed resource management scheme., This work has been partly supported by the iLAND project (ARTEMIS-JU 100026) funded by the ARTEMIS JTU Call 1 and the Spanish Ministry of Industry, Commerce, and Tourism (www.iland-artemis.org), ARTISTDesign NoE (IST-2007-214373) of the EU 7th Framework Programme, and by the Spanish national project REM4VSS (TIN 2011-28339).

Modern mobile terminal devices are multi-functional terminal devices with options such as: Internet access, using of applications, e-mail communication, messaging, data storage and using of multimedia files. The value of such data is often invaluable and vulnerability is often very high. Given the high use of smartphones and a variety of operating systems that they use (iOS, Android, Windows Phone ...), the logical is the fact that these devices are frequent targets of malicious attacks. Research of this paper will focus on defining forms of security threats and possible attacks on smartphones and a brief description of possibilities for protecting smartphones. There will be displayed features of operating systems and specified the security aspects and specifics which carry some of the modern operating systems of mobile terminal devices.

Sistemas operativos móviles más utilizados actualmente con sus funcionalidades, características y descripciones generales, efectividad y análisis realizado a 2 aplicaciones de uso masivo en Colombia. La situación planteada según las investigaciones iniciales, dan a conocer que a pesar de la gran acogida que han tenido el ingreso de los sistemas operativos móviles en Colombia (que ha sido de gran impacto en el mercado mundial) los usuarios no pueden explotar al máximo sus capacidades, debido principalmente a la falta de conocimientos respecto a los mismos, su seguridad, sus funcionalidades y sus mejores alcances. Igualmente, ha sido notable que en Colombia, a pesar de la variedad de hardware para smartphones tales como IPhone, HTC, Sony Ericsson y Nokia entre otros, que poseen tecnología de punta, hayan tenido la acogida esperada. Pero como se dijo anteriormente, el usuario final a veces no tiene conocimientos acerca de los sistemas operativos móviles que se están utilizando y por lo tanto prefieren no correr riesgos al invertir su dinero en algo que posiblemente les resulte de difícil entendimiento y que no les genera seguridad, a pesar de las bondades de las herramientas que día a día se crean y que pueden ser utilizadas por los usuarios bien sea en su vida personal o profesional y recurren a la tecnología simple como les teléfonos de segunda generación que han sido utilizado desde hace casi 20 años. Mobile ooerating systems most used nowadays with funcionalities, features and general descriptions, efectivity and a short analysis made to 2 applications with massive use in Colombia. The situation that according to initial investigations, disclosed that despite the great success they have had the income of mobile operating systems in Colombia (which has been a great impact on the world market) users can not maximize their capacity, mainly due to lack of knowledge about them, their safety, their functionality and its best. It has also been notable in Colombia, despite the variety of hardware to smartphones such as IPhone, HTC, Sony Ericsson and Nokia among others, have advanced technology, have had the anticipated interest. But as stated earlier, the end user often has no knowledge of mobile operating systems are being used and therefore prefer not to take risks by investing their money in something you may find it difficult to understand and they do not generate security, despite the benefits of the tools are created daily and can be used by users in either personal or professional life and rely on simple technology as their second-generation phones have been used for nearly 20 years.

The evolution of software ecosystems is the result of the popularity and adoption of common architectural development for multiple product development and represents a significant shift in traditional software development style and process methodology. Currently several organizations are in practice with this new process model that embraces business as one of its central factors and have thrived as a result. There can be no doubt that the development of software ecosystems have caused major players in the software industry to rethink their operating practices and engage with third parties, opening their platforms to external entities to attain business objectives. In this paper we examine four of the organizations that are at the forefront of software ecosystem adoption, specifically for mobile devices and explore their business development models. This investigation explores and compares their business process models in terms of how they engage with the external players in order to develop and distribute software and services in this changing marketplace. The study found some commonalities as well as some salient differences in their business processes and presents an assessment of the health of each mobile OS-centric ecosystem. We conclude that this study will help in further aiding understanding of the business process role in this area of ecosystem software.

Paper is a case study of mobile operating systems market, where mobile operating system makers share a distributed knowledge of mobile operating system basics and different levels of information about consumer expectations. According to the basic logics, it is reasonable to expect that if it is commonly known that a choice A is better than a choice B, any agent i will prefer the choice instead of an inferior one. In case the mobile operating system makers some chose a completely different outcome which is rather based on disruptive thinking instead of common knowledge.

The commercial mobile phone industry is a relatively new one. Starting out in the 1980s, it has proliferated in both numbers and in terms of technology. The last decade saw a sharp increase in both the number of subscribers and the amount of services which was offered by mobile devices. In order to keep up with this fast evolution of the industry, phones have started to get much more complicated and ‘smarter’ due to the software which is used to run these phones. Multi touch screen menus, High Definition video playback, multi megapixel cameras and a plethora of connectivity options are just some of the features a consumer takes for granted in his/her new mobile device. In order to provide these services to the user the software inside the phone has gotten complex to the scale of becoming its own Operating System much akin to the Operating Systems used on personal computers. These mobile operating systems contain millions of lines of software code and cost a lot of money to maintain and develop. Moreover having a popular operating system benefits the organization as it draws in many developers who can write applications which run on this operating system and also develop services which are specific to the operating systems. Having these services generate revenue for the network operators who get to bill the consumers for using the services or for the data which has been transferred to and from these mobile phones via the operator’s network. Nokia’s dominant market share in the smartphone market entails that it holds a near 40% share with its smartphone operating systems. Gradually the company has been moving towards opening up its previously proprietary operating systems to the public in the form of Open Source Software, where everyone is able to view, share, distribute and contribute to the software code. This strategy change has been taking place over the last couple of years and continues under an overall change of direction and focus which is taking place in the company. This thesis work relates as to what exactly is the current placement of Nokia in the economic and mobile devices market and how the company has been adapting to the challenges it has been facing at the hands of both old and new rivals who have been coming with innovative ideas in order to topple over Nokia from its throne of being the biggest mobile phone maker in the world. The thesis first looks at exactly what is Open Source Software. From there it gradually moves to do comparisons between closed and Open Source Software in order to give the reader an idea as to what are the pros and cons of each. In the second half of the thesis a snapshot of the current market situation and competitors is given in order to understand the environment in which Nokia has been working and developing its strategy in. Later on the thesis goes in depth about the decisions, their triggers and their implications with regards to Nokia and the use of Open Source Software as a strategy in this changing environment.
