Abstract
In addition to robustness and fragility, security is quite an important issue in media authentication systems. This paper first examines the insecurity of several block-based authentication methods under counterfeit attacks. Then, we prove that the proposed digital signature, which is composed of structural information, is content-dependent and provides security against forgery attacks. Experimental results demonstrate the benefits of exploiting structural information in a media authentication system.
