Message from the PriSecCSN2012 Workshop Chairs

The First International Symposium on Privacy and Security in Cloud and Social Networks (PriSecCSN2012) is co-located with the Second International Conference on Cloud and Green Computing (CGC2012) held on November 1-3, 2012, Xiangtan, Hunan, China. Social network analysis and cloud computing are two of the most exciting new trends in the recent developments of information technology. As the new generation computing paradigm, cloud enables computing resources to be provided as IT services in a pay-as-you-go fashion with high efficiency and effectiveness. With the popularity of social software as well as the fast development of cloud and other high-performance computing infrastructures, the outcome of social network analysis is becoming more and more attractive. However, information privacy and security issues are major challenges in both these areas. This symposium aims at providing a forum for researchers, practitioners and developers from different background areas such as distributed computing, social computing, information security and privacy protection areas to exchange the latest experience, research ideas and synergic research and development on fundamental issues and applications about security and privacy issues in cloud environments and social networks. The symposium solicits high quality research results in all related areas. PriSecCSN2012 contains 3 papers. Each of them was peer reviewed by at least three program committee members. The symposium covers a broad range of topics in the field of Privacy and Security in Cloud and Social Networks such as Security and privacy in Big Data management, Application of modern cryptography in cloud and social networks, Emerging threats in cloud-based services, Multi-tenancy related security/privacy issues, Vulnerabilities in cloud infrastructure, Security modelling and threats in cloud computing, Security/privacy in hybrid cloud, User authentication in cloud services, Information hiding, Trust and policy management in cloud, Remote data integrity protection, Securing distributed data storage in the cloud, Security and privacy in mobile cloud, Malware propagation in social networks, Information leakage via social networks, Trust and reputation in social networks, Security configuration based on social contexts groups, Online social footprints, Multi-faceted privacy preservation.
