Electronic healthcare (e-health) has gained more and more research attention in recent years, due to its flexibility and convenience. E-health is efficiently enabled by telecare medicine information system (TMIS). TMIS provides seamless transfer and timely sharing of medical information for specific healthcare services. Since communications in TMIS are carried out through unreliable channels, data security and user privacy concerns become prominent. With traditional single-server architecture, users must store massive credentials, which causes inefficient communication and significant overhead. Moreover, user credentials in previously proposed schemes are stored at server side, suffering potential risks. Our work proposes a three-factor user-controlled single sign-on (UCSSO) with fast authentication and privacy protection for TMIS. The contributions of this paper are as follows. Our work integrates three factors including password, smart card and biometrics in authentication procedure, for providing a high-security and privacy-preserved communication. We introduce single sign-on solution that allows users to log in to multiple servers using a single password. User-controlled mechanism is proposed to address insider attacks and the risk that registration center may be compromised. The proposed scheme is designed with fast authentication mechanism that helps to efficiently establishes new session key. Our work is proved secure using BAN logic, ROR model, and AVISPA toolset. The results of performance comparison show that our scheme provides more security properties and bears the least overhead, compared with competitive schemes.

The fifth generation (5G) mobile network delivers high peak data rates with ultra-low latency and massive network capacity. Wireless sensor network (WSN) in Internet of Thing (IoT) architecture is of prominent use in 5G-enabled applications. The electronic healthcare (e-health) system has gained a lot of research attention since it allows e-health users to store and share data in a convenient way. By the support of 5G technology, healthcare data produced by sensor nodes are transited in the e-health system with high efficiency and reliability. It helps in reducing the treatment cost, providing efficient services, better analysis reports, and faster access to treatment. However, security and privacy issues become big concerns when the number of sensors and mobile devices is increasing. Moreover, existing single-server architecture requires to store a massive number of identities and passwords, which causes a significant database cost. In this paper, we propose a three-factor fast authentication scheme with time bound and user anonymity for multi-server e-health systems in 5G-based wireless sensor networks. In our work, the three-factor authentication scheme integrating biometrics, password, and smart card ensures a high-security sensor-enabled environment for communicating parties. User anonymity is preserved during communication process. Besides, time bound authentication can be applied to various healthcare scenarios to enhance security. The proposed protocol includes fast authentication, which can provide a fast communication for participating parties. Our protocol is also designed with multi-server architecture to simplify network load and significantly save database cost. Furthermore, security proof and performance analysis results show that our proposed protocol can resist various attacks and bear a rational communication cost.

This study explores the early stages of the female entrepreneurial process from conception to venture start up. Seventy-eight female entrepreneurs' stories, published on the Flying Goose Program website, were collected and analyzed by content. Engaged in different industries, they are mostly small- and medium-sized enterprises or microenterprises in personal service industry. The results describe the women entrepreneur as: middle-aged, married, college degree, with work experience, no management experience, no financial backup, mostly in traditionally personal service industry. In addition to their dreams, interests, and specific skills and knowledge, these women have a desire to solve life problems or assist disadvantaged groups in society. When they have an entrepreneurial idea, they are likely to share it with and receive approval and affirmation from their families-particularly their husbands. Government assistance is a major factor affecting their venture start up decision making. They access related business knowledge from training courses. Practical and policy implications for female entrepreneurship are provided. [ABSTRACT FROM AUTHOR]

As one of Asia's most economically successful nations, Taiwan relies mainly on external trade and small- and medium-size enterprises (SMEs) involved in value-added activities. But even with limited resources and capabilities, SMEs in Taiwan can still successfully build brand equity by concentrating and combining internal and external resources to gradually accumulate entrepreneurial capabilities and achieve stable growth. This multiple case study compares and contrasts 4 SMEs in Taiwan. Data from in-depth interviews and secondary data were compared and analyzed. The results show that entrepreneurs of case companies influence how companies allocate their resources and capabilities. Their vision of building the best brand using limited resources allows them to target appropriate international customers and, through the implementation of branding strategy and marketing activities, create unique and varied product portfolios. A framework is proposed that combines the relationships among market, business type, and capabilities development for SME brand building. [ABSTRACT FROM AUTHOR]
