Robust hash functions for visual data need a feature extraction mechanism to rely on. We experimentally compare spatial and transform domain feature extraction techniques and identify the global DCT combined with the cryptographic hash function MD-5 to be suited for visual hashing. This scheme offers robustness against JPEG2000 and JPEG compression and qualitative sensitivity to intentional global and local image alterations.
