Data origin and data integrity authentication are, very important factors in image and video security. As modern image and video coding techniques become standards, authentication methods should be devised that cope with the modern standards' intrinsic capabilities: scalability and a trend towards more content-oriented compression. So far no efficient authentication system addresses these properties.. The design of an efficient scalable authentication technique under reasonable system considerations is reviewed. The technique addresses modern coding standards such as JPEG2000 and MPEG4. In addition, the authentication method is enhanced by introducing novel cryptographic primitives that further enhance the method's applicability to real-world scenarios.
