Paper Title - A Public Key Watermarking Scheme For Image Authentication
Conventional digital signature schemes for image authentication encode the signature in a file separate from the
original image, thus require extra bandwidth to transmit it. Watermarking techniques embed some information in the host
image. In this paper, a public key based digital signature scheme for image authentication is proposed. The scheme extracts
feature value from the pixels of the of the original image. This feature is used to compute the signature which is embedded
into the DCT of the image as watermark, avoiding additional signature file. It is inspired by Wong’s Public Key
Watermarking scheme which was later enhanced by Baretto. The watermarked image demonstrated high perceptual quality
and robustness. It also proved to be robust against many common image processing operations and JPEG compression. The
scheme not only can verify the authenticity and the integrity of images, but also can locate the illegal modifications.
