Abstract

This chapter is intended to disseminate the concept of digital signature-based image authentication. Capabilities of digital signature-based image authentication and its superiority over watermarking-based approaches are described first. Subsequently, general models of this technique — strict authentication and non-strict authentication are introduced. Specific schemes of the two general models are also reviewed and compared. Finally, based on the review, design issues faced by the researchers and developers are outlined.
