Call for Paper - TrustBus'12 9th International Conference on TRUST, PRIVACY AND SECURITY IN DIGITAL BUSINESS in conjunction with DEXA 2012 Vienna University of Technology, Austria, September 3 - 7, 2012 (Submission deadline : April 6, 2012) The advances in the Information and Communication Technologies (ICT) have raised new opportunities for the implementation of novel applications and the provision of high quality services over global networks. The aim is to utilize this 'information society era' for improving the quality of life for all citizens, disseminating knowledge, strengthening social cohesion, generating earnings and finally ensuring that organizations and public bodies remain competitive in the global electronic marketplace. Unfortunately, such a rapid technological evolution cannot be problem-free. Concerns are raised regarding the 'lack of trust' in electronic procedures and the extent to which 'information security' and 'user privacy' can be ensured. In answer to these concerns, the 9th International Conference on Trust, Privacy and Security in Digital Business (TrustBus'12) will provide an international forum for researchers and practitioners to exchange information regarding advancements in the state of the art and practice of trust and privacy in digital business.
