A Multi-feature Based Invertible Authentication Watermarking for JPEG Images

: Invertible authentication techniques have been used in some special applications (such as medical or military) where original data can be recovered after authenticated. In this paper, we combine features (relation of coefficients) in DCT domain with content features (edges or texture) of JPEG image into multi-features, which are useful to authenticating images from both spatial and frequency domains. A novel invertible data embedding mechanism based on random walk is proposed. Experimental results show that the algorithm is sensitive to intended tampers while accepting appropriate JPEG recompression, and further can locate corrupt areas. Compared with authentication scheme based on features extracted from single domain, the probability of our “miss alarm” is lower.
