Figure 20From: Key-Dependent JPEG2000-Based Robust Hashing for Secure Image AuthenticationHamming distances among hash strings generated with 100 random keys: hash of the original images is compared to a hash from a compressed image at 0. 05 bpp (16-byte hash at decomposition depth 7 versus 128-byte hash at decomposition depth 6); distances are accumulated from 20 images.Back to article page
