The existing digital data authentication methods are able to detect tampered regions, but are too fragile to resist incidental distortions. This paper will present a new digital signature scheme for image authentication by making use of image content (in the wavelet domain). Based on this concept, a structural digital signature (SDS) is constructed. SDS is a signature that can be used to judge whether an incoming modification is incidental or malicious. When the structure of an SDS is maintained near-complete, we classify the incoming modification as incidental; otherwise, it is malicious. Many incidental manipulations, which cannot be tolerated in previous digital signature or fragile watermarking methods, can now survive under the proposed scheme.
