12 Secure Retrieval and Dissemination of Information (text and image) in Distributed and Wireless Specific- purpose Environments (RDI) Organizers Christos Skourlas and Eleni Galiotou As mobile devices are enhanced continuously with more resources, wireless infrastructures provide support to a growing number of specific purpose environments. Advances on sensor technology, wireless environments, Information Retrieval, Personalization, and Content Based Image Retrieval introduce new possibilities in various sectors, realizing the anytime-anywhere access to multimedia information. This Special Session investigates Secure Retrieval and Dissemination of Information (text and image) in Distributed and Wireless specific purpose Environments (SECRET_DIDWE). The SECRET_DIDWE session aims at providing researchers and professionals with an insight on: Wireless architectures to enable authorized users to access sensitive information in a secure and transparent manner. Policy-based architectures utilizing wireless sensor devices, advanced network topologies and software agents. Applications related to remote monitoring of patients, elderly people, etc. Evaluation and Integration of Information Retrieval and Personalization techniques: Text Retrieval, and Content Based Image Retrieval techniques. Classification based on various techniques e.g. neural network techniques, fuzzy techniques, and its applications. Topics include, but are not limited to the following: Security issues in IT applications. Benchmarks and evaluation of the applications Specific purpose Wireless architectures Agent based architectures. Transparent Information transfer using intelligent agents. Authentication and information access and retrieval in ad-hoc networks and self-organized networks Policies and policy-based architectures Novel methods for Text Retrieval, personalization, and Content Based Image Retrieval and application in specific purpose environments

13 Transparent and secure communication in distributed environments Advanced remote medical treatment services through pervasive environments- Remote monitoring of patients and elderly people Neural network techniques and its applications e.g. SVM based systems that support diagnosis Sociomaterial design in IS and HCI (SD) Organizers Demosthenes Akoumianakis and Mikael Wiberg This special session is dedicated to exploring the synergy between two evolving streams of research, namely sociomateriality as populated in the Information Systems research community and the material turn as advocated in HCI. Sociomateriality features the entanglement of social and material agencies that shape organizational practices. The material turn coins a shift in design perspective to acknowledge the role of digital technologies as materials for crafting novel user experiences. In recent years, both constructs have received considerable attention in several academic venues, resulting in an on-going effort to consolidate experience and build a shared vocabulary. In this vein, and by focusing at the cross-roads of these emerging traditions, the special session invites research contributions covering, but not limited to, the following areas: Theoretical treatments of digital materiality From socio-technical systems to sociomaterial studies of IT in organizations Methods for studying sociomaterial entanglements & assemblages Materiality of interactions New constructs for theorizing materiality (i.e., texture, light, gravity,etc.) Novel digital assemblages and emerging interaction paradigms Computational composites Software as material Services as material Transformative technologies, semantic APIs and exploratory visualization

14 Emerging Technologies for the Internet-of-Things (ET-IoT) Organizers Constantine Spyropoulos, Dimosthenis Kothris and Konstantina Kanellopoulou Recent advances in intelligent computer systems and communications have created the necessary conditions for the networking of a wide variety of heterogeneous devices. This has led to the integration of short-range mobile transceivers into everyday life objects and has enabled new forms of communication between objects and even between people and objects. The concept of smart devices, i.e. the inclusion of software, identifiers and networking to devices typically not computerized, has led to the so-called Internet of Things (IoT). Topics include, but are not limited to the following: Architectures for the IoT IoT Standardization (networking protocols, network design, system architectures) IoT applications (Smart Cities, Transportation, Health, Smart Grid, etc.) Social acceptance, security, and privacy preservation of IoT systems Experiences with Open Platforms and hardware within IoT Interoperability, Scalability and Complexity of IoT systems Cloud computing for Big data management Context-awareness and knowledge extraction Secure IoT communications Body sensor networks Energy-efficiency in Wireless Sensor Networks (WSN) Mobile Communications and mobility in WSN Performance Analysis of Wireless Sensor Networks Machine-to-Machine (M2M) Communications New business models
