PRISMS is the successor of MobiSec (International Conference on Security and Privacy in Mobile Information and Communication Systems). The conference under a new name (PRISMS) is organized this year with the co-sponsorship of IEEE. Its focus is the convergence of information and communication technology in mobile scenarios. This convergence is realised in intelligent mobile devices, accompanied by the advent of next-generation communication networks. Privacy and security aspects need to be covered at all layers of mobile networks, from mobile devices, to privacy respecting credentials and mobile identity management, up to machine-to-machine communications. In particular, mobile devices such as Smartphones and Internet Tablets have been very successful in commercialization. However, their security mechanisms are not always able to deal with the growing trend of information-stealing attacks. As mobile communication and information processing becomes a commodity, economy and society require protection of this precious resource. Mobility and trust in networking go hand in hand for future generations of users, who need privacy and security at all layers of technology. In addition, the introduction of new data collection practices and data-flows (e.g. sensing data) from the mobile device makes it more difficult to understand the new security and privacy threats introduced. PRISMS strives to bring together the leading-edge of academia and industry in mobile systems security, as well as practitioners, standards developers and policymakers. Contributions may range from architecture designs and implementations to cryptographic solutions for mobile and resource-constrained devices.
