“…So, the tampering coincidence problem is avoided. This thought is also reflected in the other schemes [14][15][16][17][18][19]. In [17], the reference sharing mechanism for watermark self-embedding is extended.…”

This paper presents a reference sharing mechanism-based self-embedding watermarking scheme. The host image is embedded with watermark bits including the reference data for content recovery and the authentication data for tampering location. The special encoding matrix derived from the generator matrix of selected systematic Maximum Distance Separable (MDS) code is adopted. The reference data is generated by encoding all the representative data of the original image blocks. On the receiver side, the tampered image blocks can be located by the authentication data. The reference data embedded in one image block can be shared by all the image blocks to restore the tampered content. The tampering coincidence problem can be avoided at the extreme. The maximal tampering rate is deduced theoretically. Experimental results show that, as long as the tampering rate is less than the maximal tampering rate, the content recovery is deterministic. The quality of recovered content does not decrease with the maximal tampering rate.

“…The reference information is not the representative data of the original image blocks. The reference data is generated by encoding the representative information [12][13][14][15][16][17][18][19][20][21][22][23]. In [12,13], the reference sharing mechanism for watermark selfembedding is proposed.…”

“…The length of the block CC based on DCT can adjust flexibly to the requirement of recovery quality [4]. The block CC based DCT was adopted and improved by many researchers [5][6][7]. Qian et al [6,7] proposed the multi-level encoding to generate the block CC with variable length for various types of blocks.…”

Abstract. Combined average encoding with vector quantization (VQ) encoding, a new self-embedding fragile watermarking scheme is proposed. To take into account watermark payload, localization accuracy and recovery quality, the 6-bit average-watermark of a 2 × 2 original block and the 8-bit VQ-watermark of a 4 × 4 block of image high-frequency component are generated and hidden in the corresponding mapping blocks of them based on secret key, respectively. To improve the tamper detection performance, the validity of a 2 × 2 block is determined by combining the average-watermark with the VQ-watermark. The average, VQ and inpainting recovery operations are executed in sequence to improve the recovery quality especially for a larger tampering ratio. Simulation results demonstrate that the proposed scheme not only provides a better invisibility and security against the known counterfeiting attacks, but also allows image recovery with an acceptable visual quality up to 70% tampering ratios.

“…To accurately identify the tampered blocks, Lin et al [6] proposed a hierarchical digital watermarking scheme for tamper detection and recovery, and he used a 3-level hierarchical structure to locate the tampered regions, but there was no second chance to recover tampered blocks whose watermark bits embedded in the other block were destroyed. To overcome this problem, Qian [7] hided the restoration-bits into the 3-LSB layers of the host image to improve the reconstructed image quality, the quality of recovered image was improved, but the quality of watermarked image decreased due to the increased watermark payload. In [8], the quantized DCT coefficients of each block replaced the 2-LSB of another block.…”

Abstract-To address issues of content authenticity verification and integrity protection, a stereo image watermarking method based disparity is proposed. Firstly, the stereo image blocks are classified into eight types according to the smoothness of it, and the alterable-length recovery bits are generated. The recovery bits include foremost bits, detail bits, type bits and disparity bits. Foremost bits are embedded twice for improving quality of recovery. Moreover, disparity is embedded as well for recovery further. At the receiver side, recovery bits extracted from watermarked stereo image not only localize tampered regions, but also recover them. The visual quality of the watermarked stereo image is imperceptible due to the low embedding volume. Experimental results show that the proposed method can detect tamper precisely and provide high restoration quality.
