The workshop covers all technical aspects of security applications, including cryptographic and non-cryptographic techniques. We were very pleased and honored to serve as the Program Committee Co-chairs of WISA 2007. The Program Committee received 95 papers from 20 countries, and accepted 27 papers for the full presentation track. The papers were selected after an extensive and careful refereeing process in which each paper was reviewed by at least three members of the Program Committee. In addition to the contributed papers, the workshop had three special talks. Moti Yung gave a tutorial talk, entitled “Somebody You Know: The Fourth Factor of Authentication.” Kihong Park and Nasir Memon gave invited talks, entitled “Reactive Zero-Day Attack Protection” and “Securing Biometric T- plates,” respectively. Many people deserve our gratitude for their generous contributions to the success of the workshop. We would like to thank all the people involved in the technical program and in organizing the workshop.
