Abstract

Many watermarking schemes have been proposed to protect the authority of the image producer. These schemes can help the image producer to assert the ownership when their images are illegal reproduced. A buyer may want to make sure that the received commodity is from the legal sender and prove its integrity. In this situation, digital signature schemes can meet these requirements. In this sender-receiver protocol, images are always compressed before transmission. So compression tolerant image-features have to be designed to replace the hash functions in conventional digital signature schemes. In this paper, a public-key based fault resilient and compression tolerant digital signature is proposed. The proposed method can not only verify the authenticity and the integrity of commodities, but also can locate the illegal modifications. Furthermore, the proposed method can provide the capability of recovery if images are tampered.
