This book constitutes the thoroughly refereed post-conference proceedings of the workshop on
Usable Security USEC 2012 and the third Workshop on Ethics in Computer Security Research
WECSR 2012 held in conjunction with the 16th International Conference on Financial Cryptology
and Data Security FC 2012 in Kralendijk Bonaire. The 13 revised full papers presented were
carefully selected from numerous submissions and cover all aspects of data security. The goal
of the USEC workshop was to engage on all aspects of human factors and usability in the context
of security. The goal of the WECSR workshop was to continue searching for a new path in
computer security that is Institutional review boards at academic institutions as well as
compatible with ethical guidelines for societies at government institutions.
