“…Once the RI for each 16 × 16 non-overlapping block is generated, a reference matrix M as shown in Figure 6 is constructed according to Equation (9). This matrix acts as a reference table to embed recovery information RI into processed image I p .…”

“…Early approaches to fragile watermarking only focused on locating tampered areas in a watermarked image. Later, in order to retain the usability of damaged images, some schemes were designed with recovery features to produce fragile watermarking [4][5][6][7][9][10][11][12]15,16,20,25]. Recovery information stored in nontampered image areas is used to repair the tampered areas as long as the tampered areas are localized.…”

In this paper, we first designed Huffman code (HC)-based absolute moment block truncation coding (AMBTC). Then, we applied Huffman code (HC)-based absolute moment block truncation coding (AMBTC) to design a pixel pair-wise fragile image watermarking method. Pixel pair-wise tampering detection and content recovery mechanisms were collaboratively applied in the proposed scheme to enhance readability even when images have been tampered with. Representative features are derived from our proposed HC-based AMBTC compression codes of the original image, and then serve as authentication code and recovery information at the same time during tamper detection and recovery operations. Recovery information is embedded into two LSB of the original image with a turtle shell-based data hiding method and a pre-determined matrix. Therefore, each non-overlapping pixel-pair carries four bits of recovery information. When the recipient suspects that the received image may have been tampered with, the compressed image can be used to locate tampered pixels, and then the recovery information can be used to restore the tampered pixels.

“…Hence, this technique conveniently provides remote health monitoring facility. There are different kinds of approaches in which MIW can be easily carried out that is, spatial domain 10,11 and transform domain. 12,13 Transform domain approach is far better as compared to spatial domain in terms of robustness.…”

In this paper, a novel medical image watermarking (MIW) technique for tele ‐ medicine applications is proposed. In this approach homomorphic transform (HT), redundant discrete wavelet transform (RDWT) and singular value decomposition (SVD) transforms are successfully utilized for developing an effective watermarking technique. Reflectance component of medical host image is obtained using HT, on which RDWT decomposition and SVD are applied. Similarly medical watermark image is processed with RDWT and SVD. Singular values (Svs) were used for embedding the watermark image into host image. 2‐D chaotic Arnold transform (AT) is used for providing extra security to the watermark image by encrypting the watermarked image. Moreover, proposed technique is also tested for several wavelet families. Robustness and imperceptibility of the proposed technique is enhanced as depicted in experimental results under various attacks. Furthermore, better robustness is attained from proposed technique on comparing it with other formerly reported schemes.

“…In fragile watermark any trivial modification in watermarked image leads to destroy the watermark. [1][2][3] Fragile watermark is used for image tamper detection due to its sensitivity for alteration in image. One type of the fragile watermarking approach divides a host image into small blocks, [4][5][6][7][8] and insert the fragile watermark into these blocks.…”

This paper suggests an efficient fragile watermarking scheme for image content authentication along with altered region restoration capability. In this scheme, image is divided into nonoverlapping blocks of size 2 × 2 and for each block, eight bits for image content recovery data and four bits for authentication data from five most significant bits (MSBs) of each pixel, are generated. These 12 bits are embedded into the least significant bits (LSBs) of the pixels which are placed in its corresponding mapping block. At the receiver end by comparing the recalculated and extracted authentication data, the tampered blocks can easily be identified and using recovery data, one can easily restore the tampered block. Results of experiments demonstrate that the proposed scheme is effective enough for alteration detection as well as tamper recovery of the image.
