Fragile watermarking scheme for image authentication
Hongtao Lu, Ruiming Shen, Fu-Lai Chung · Electronics Letters · 2003
A simple fragile watermarking scheme for image authentication is proposed. The insertion of a binary watermark is accomplished by replacing the least significant bit of the host image with a random binary image obtained by random permutations and suitable XOR operations among bitplanes. The proposed scheme is secure, fast, and capable of detecting and localising modification, and is immune of the well-known quantisation attack.
