Reversible (invertible, lossless) authentication draws much attention recently for its ability to restore the original image from marked image without any distortions upon verification. In this paper, we propose a reversible watermarking scheme for image authentication based on histogram modification in integer wavelet transform (IWT) domain. The proposed scheme has features: i) Reversibility, high embedding capacity, and good perceptual invisibility; ii) Tamper localization and discerning; iii) Detection without requiring explicit knowledge of the original image; iv) Verification before reconstruction of the original image, therefore computational require- ments are reduced when reconstruction isn’t needed. To our best knowledge, none of the reversible authentication schemes reported in the literature has all of the features. Those features make the proposed scheme practical, effective and appealing for strict content integrity authentication system. Experimental results demonstrate the feasibility and validity of the proposed scheme.
