Secret sharing based on absolute moment block truncation coding (AMBTC) has been widely studied. However, the management of stego images is inconvenient as they seem indistinguishable. Moreover, there exists a problem of pixel expansion, which requires more storage space and higher transmission bandwidth. To conveniently manage the stego images, we use multiple cover images to make the stego images seem to be visually different from with each other. Futhermore, the stego images are different, which will not cause the attacker's suspicion and increase the security of the scheme. And traditional Visual Secret Sharing (VSS) is fused to eliminate pixel expansion. After images are compressed by AMBTC algorithm, the quantization levels and the bitmap corresponding to each block are obtained. At the same time, when the threshold is (k, k), bitmaps can be recovered losslessly, and the slight degradation of image quality is only caused by the compression itself. When the threshold is another value, the recovered image and the cover images can be recovered with satisfactory image quality. The experimental results and analyses show the effectiveness and advantages of our scheme.

Watermarking is a method of protecting multimedia material, especially images, from malicious attacks by embedding a fingerprint. Whenever it comes to sensitive pictures, such as medical images, traditional watermarking methods, on the other hand, show their limitations. Indeed, the additional mark typically alters the picture in an irreversible manner and may conceal small details. In this paper, we propose a watermarking technique for patient identification and watermark integrity proof to solve these concerns. This approach uses a two-part watermark: the first carries the patient's information fingerprint, and the second includes the patient's encrypted photography. The frequency content of the image is extracted using a redundant discrete wavelet transform in this method. The resulting coefficients are then subjected to Schur decomposition, and the watermark bits are integrated by altering the least significant bit of the Eigen values. This method's capacity enables the integration of the patient's picture and fingerprint, as well as the insertion of an error-correcting code. The coefficient manipulation of the integration process allowed the watermark to be almost completely hidden. As a consequence, we were able to create a watermarked image that looked similar to the original. The method's performance, as well as its resistance to JPEG compression and noise addition, were evaluated through experiments on test images. However, these values are sometimes far from the optimal value of 1 for normalized correlation.

In this paper, we propose a data hiding scheme which uses our modified AMBTC compression technique for embedding the secret data. Our modified AMBTC technique converts the one bit plane into two bit plane which helps in achieving better quality compressed image as well as high capacity. In this scheme, we first apply the original AMBTC technique on the given cover image then identify the smooth and complex blocks using a user defined threshold value. In case of the smooth blocks, it converts the one bit plane into two bit plane using mean value of the block and replaces all the bits of the bit plane with the secret data bits. It calculates four quantization levels in place of two old quantization levels. In case of complex blocks, it converts the one bit plane into two bit plane but here only the first LSBs of the newly constructed bit plane is replaced by the secret data bits. The four new quantization levels are calculated using the resultant bit plane. Thus, this scheme is able to embed 2 bits into each pixel of the smooth blocks and one bit in each pixel of complex blocks. It provides good quality stego image because the introduced error during the secret data embedding is reduced by having four quantization levels. Experimentally, our scheme is superior to the existing AMBTC based data hiding schemes in terms of both data hiding capacity and image quality. In fact, the proposed scheme hides approximately two times more secret data than the existing schemes with better image quality.

This paper presents a secret sharing scheme to encode a secret binary image in images which are compressed by absolute moment block truncation coding (AMBTC) method. The generated shadows by the proposed scheme are in AMBTC-compressed format and meaningful, the visual quality of which is the same as that of its original AMBTC version. In the proposed scheme, the secret image can be reconstructed in two situations: (1) if some light-weight computational devices are available, the secret image can be completely decrypted without any distortion, and (2) otherwise, the secret image can also be revealed by human visual system. Furthermore, the proposed scheme provides the reversibility for protecting the valuable cover images. In addition, underlying the proposed (2,2) scheme, this paper gives a construction for the (2, n) scheme where one participant may require more than one shadow. Theoretical analysis and simulation results demonstrate the superiority of the proposed scheme. (c) 2014 Elsevier Inc. All rights reserved.

Image steganography is one of the most important research areas of information security where secret data is embedded in the images to conceal its existence while getting the minimum possible statistical detectability. To achieve a good tradeoff between the hiding capacity and image quality, more work needs to be further researched. In this paper, we propose high capacity data hiding scheme by employing the absolute moment block truncation coding (AMBTC) compression. It exploits the redundancy of blocks of the AMBTC-compressed image to embed the secret data. The pixel values of the AMBTC-compressed image are modified at most by one for hiding the secret data. Thus, it is able to maintain the stego-image quality after hiding the secret data. Experimental results validate the effectiveness of the proposed scheme and show that it outperforms various existing methods in terms of both hiding capacity and stego-image quality.

Shares in image secret sharing play a vital role. These image shares has size greater than or equal to size of original image, it require high bandwidth while transmission. Because of the excessive bandwidth requirements of image there is need to reduce the bandwidth of images. To reduce the size of image, Huffman compression coding techniques are used. By reducing the image share size in Thien and Lin's secret sharing scheme using Huffman coding technique leads to reduced bandwidth overhead. In proposed approach Huffman coding is applied on secret image before applying secret sharing. This approach helps to increase the compression ratio of share images by 14% than existing system.

In 2014, Lo et al. employs the histogram shifting technique to present a reversible data hiding scheme for the "absolute moment block truncation coding image" (AMBTC). In their scheme, the secret message is embedded into the quantization levels. The bitmaps in their scheme cannot carry any secret message. The embedding capacity of their scheme is lower. Thus, in this paper, a reversible data hiding scheme based on AMBTC is proposed with the purpose of enhancing the embedding capacity. Experimental results demonstrated that the embedding capacity of our scheme is higher than those of the Lo et al.'s scheme.

In this paper, a new color image compression algorithm based on absolute moment block truncation coding (AMBTC) and entropy coding is proposed. The AMBTC improves the compression performance of block truncation coding (BTC) obviously. A novel technique by using eight different types of bitmap tables is developed for the proposed algorithm. In addition, an entropy coding technique combining prediction and Huffman coding approach is included in the proposed algorithm and decreased the data amount of luminance images. The experimental results show that more than 82% data amount can be compressed by using the eight different types of novel bitmap tables. Compared with previous studies, this work has better compression performance than previous 4*4 BTC, JPEG, and JPEG-LS algorithms.

A novel hybrid image authentication scheme is proposed in this paper to protect the integrity of images that are compressed by absolute moment block truncation coding (AMBTC). In this proposed scheme, all blocks of a compressed image are classified into two groups. For smooth blocks, the authentication code for each block will be embedded into the bitmap of each block. For complex blocks, the authentication code will be embedded into quantization levels of each block according to a reference table. The experimental results show that this proposed scheme achieves high image quality of the embedded image and almost 100 % detection precision when eb = 3.

In the transmission of hyperspectral images that have been compressed using absolute moment block truncation coding (AMBTC), confidentiality and security of crucial information is often a concern. Although many data hiding (DH) methods based on AMBTC work well in guaranteeing a large amount of secret information can be embedded, the requirements of actual user scenarios, such as reversibility and imperceptibility, are degraded sometimes. To address these challenges, we propose an embedding pattern that utilizes bitmap prediction to embed secret information within the bitmaps while preserving the standard format of AMBTC codes and enabling recovery of the cover image without loss. Our proposed method, therefore, belongs to the category of reversible data hiding (RDH) techniques. Since the embedding distortion (ED) reduction is an essential object, an adaptive embedding order based on the features of AMBTC codes is conducted. Furthermore, we propose a dynamical embedding scheme to reduce ED when we are striving to achieve a larger embedding capacity (EC).
