Toward a secure JPEG
In this paper, we propose a Secure JPEG, an open and flexible standardized framework to secure JPEG images. Its goal is to allow the efficient integration and use of security tools enabling a variety of security services such as confidentiality, integrity verification, source authentication or conditional access. In other words, Secure JPEG aims at accomplishing for JPEG what JPSEC enables for JPEG 2000. We describe in more details three specific examples of security tools. The first one addresses integrity verification using a hash function to compute local digital signatures. The second one considers the use of encryption for confidentiality. Finally, the third describes a scrambling technique.
