Wie sich die Transformation moderner Gesellschaften in den nächsten Jahren fortsetzt, hängt ganz zentral von der Entwicklung, Implementierung und sozialen Kontrolle der GNR-Technologien (der Kombination aus Gen-, Nano- und Robotertechnologie) ab. Die Diskussion zur künstlichen Intelligenz, die im letzten Jahrzehnt geführt worden ist, hat mit dem Gebiet der Robotertechnologie gleichsam eine neue Arena gefunden und sich auf dieses Gebiet verlagert. Hier werden jetzt grundlegende, auch pädagogisch zentrale Fragen, wie z.B. die nach einem Personenkonzept, diskutiert (vgl. Richards u.a. 2002). Zentrale Bedenken, die sich auf die mit den neuen Technologien verbundenen Gefahren stützen, sind immer wieder vorgetragen worden (Joy 2000; Moravec 1999). Ohne diese verzweigte Debatte an dieser Stelle rekonstruieren zu wollen, kann doch ein Befund in verallgemeinernder Absicht hervorgehoben werden: In dem Maße, in dem Gesellschaften aufgrund des Einsatzes neuer Technologien einen Komplexitätsschub aufweisen, der sich bis in die Lebenswelten einzelner Menschen hinein auswirkt, rückt ein „Mechanismus“ von Sozialität immer stärker in das Zentrum der Aufmerksamkeit: Vertrauen. Nicht nur aus der hier herangezogenen Perspektive wird diese Ressource prekär. Vielmehr ist seit Beginn der neunzehnhundertneunziger Jahre ein Ansteigen der Publikationen zu dem Thema Vertrauen aus verschiedenen Perspektiven zu konstatieren, und zwar in Soziologie, Pädagogik, Philosophie, Politikwissenschaft und Ökonomie. Vertrauen wird als elementare Voraussetzung sozialer Prozesse gesehen. Wenn Vertrauen aber nicht mehr als selbstverständliche Voraussetzung sozialer Prozesse verstanden werden kann, häufen sich Maßnahmen zur Vertrauensbildung, gerät das Phänomen Vertrauen also in den Fokus der systematischen Reflexion., How the transformation of modern societies continues in the coming years depends very centrally on the development, implementation and social control of GNR technologies (the combination of genetic, nano and robotic technologies). The discussion on artificial intelligence that has taken place over the last decade has found a new arena, as it were, with the field of robotics technology and has shifted to this area. Here, fundamental, also pedagogically central questions, such as that of a concept of person, are now being discussed (cf. Richards et al. 2002). Central concerns based on the dangers associated with the new technologies have been raised again and again (Joy 2000; Moravec 1999). Without wishing to reconstruct this ramified debate here, one finding can be highlighted in general terms: To the extent that societies are experiencing a surge in complexity due to the use of new technologies, which is having an impact on the life worlds of individual people, a "mechanism" of sociality is increasingly becoming the focus of attention: trust. It is not only from the perspective used here that this resource becomes precarious. Rather, since the beginning of the nineteen-nineties, there has been an increase in publications on the topic of trust from various perspectives, namely in sociology, pedagogy, philosophy, political science and economics. Trust is seen as an elementary prerequisite of social processes. However, if trust can no longer be understood as a self-evident prerequisite of social processes, measures to build trust accumulate, the phenomenon of trust thus becomes the focus of systematic reflection.

Steganographie ist die Kunst der vertraulichen Kommunikation. Anders als in der Kryptographie, wo der Austausch vertraulicher Daten für Dritte offensichtlich ist, werden die vertraulichen Daten in einem steganographischen System in andere, unauffällige Coverdaten (z.B. Bilder) eingebettet und so an den Empfänger übertragen. Ziel eines steganographischen Algorithmus ist es, die Coverdaten nur geringfügig zu ändern, um deren statistische Merkmale zu erhalten, und möglichst in unauffälligen Teilen des Covers einzubetten. Um dieses Ziel zu erreichen, werden verschiedene Ansätze der so genannten minimum-embedding-impact Steganographie basierend auf Syndromkodierung vorgestellt. Es wird dabei zwischen Ansätzen basierend auf stochastischen und auf deterministischen Matrizen unterschieden. Anschließend werden die Algorithmen bewertet, um Vorteile der Anwendung von Syndromkodierung herauszustellen.

This report results from a contract tasking Otto-von-Guericke University of Magdeburg as follows: Within the work on the POWER project the overall problems of realizing information assurance (trustworthiness in the sense of integrity and confidentiality) and information provenance (specifically authentication of digital data objects and their origin) with digital watermarking as an alternative or complement to cryptography for several application scenarios is addressed. The current problem in the application of watermarking techniques is that, while hundreds of different digital watermarking algorithms (as primitives or building blocks) exist, watermarking protocols (the rules for combining the building blocks into a working data communication system) are still a rather immature research field. But exactly such protocols would be required for the implementation of multi-user multiaccess / hierarchical-access scenarios as they are envisioned within POWER., AFRL-AFOSR-UK-TR-2011-0005.

This publication contains the abstracts of all papers which were presented during the workshop "Pattern Recognition for IT Security", held on September 21, 2010 in Darmstadt in conjunction with the 32nd Annual Symposium of the German Association for Pattern Recognition (DAGM 2010).

Objective of this research in object-based annotation watermarking is to address the problem of Nested Object-based Embedding for hierarchical object compositions in images. Here it is necessary that each annotation does not interfere with any other annotation within the image and furthermore, it is also desirable that the relationship between annotations can directly be expressed by the structure of the different watermarks. The concept of addressing these research challenges has been structured in two main research tasks: A) Hyperlink-Graph-Concept: Formal model for representing objects and information in hierarchical structures; and B) Formal requirements and general design approach for signal-level watermark inheritance., Grant 06-3019.

The Audio WET system is a web-based evaluation system which provides the user the functionality of different watermarking algorithms (embedding and detecting) with a large database of audio signals (test material). The system also provides both single and profile attacks which can be used to evaluate the watermarking algorithms. The user has the choice to specify the watermarking algorithms with their parameters for embedding and the type of audio content. Furthermore, the user selects the properties of the watermarking algorithms to be evaluated before starting the evaluation process., The original document contains color images.

Intrusion detection systems (IDS) provide security for network systems. They are used in computer networks to detect violations against security policies or unusual events that could lead towards a security thread. Telephone networks based on the internet protocol (IP) called IP telephony (IPT) are a recent development in network usage and will become a common application in the next years as they can provide integrated services based on telephony communications. We identify IPT security demands as well as risks and analyze the possibility of adding IDS concepts to IPT systems. Digital audio watermarking is a technology able to provide different security aspects in this context. The combination of classic IDS and audio watermarking leads to new and promising way of user and data authentication and monitoring of calls.
