Abstract
Digital content authentication and preservation is an extremely challenging task in realizing decentralized digital libraries. The concept of compensated signature embedding is proposed to develop an effective multimedia content authentication system. The proposed system does not require any third party reference or side information. Towards this end, a content-based fragile signature is derived and embedded into the media using a robust watermarking technique. Since the embedding process introduces distortion in the media, it may lead to authentication failure. We propose to adjust the media samples iteratively or using a closed form process to compensate for the embedding distortion. Using an example image authentication system, we show that the proposed scheme is highly effective in detecting even minor modifications to the media.Keywords
