Abstract :
Security holes resulting from the independence of pixels in the existing fragile watermarking technique with pixel-precise localization have been pointed out. In this paper, the security of an algorithm with precise localization is analyzed. Vector quantization (VQ) attack, collage attack and oracle attack are implemented on the algorithm. Theoretical analysis and simulation results show that the algorithm has poor security, and is vulnerable to collage attack and oracle attack.
