“…Since the computation cost of AMBTC is even lower than BTC, it has been widely applied in diverse areas, such as remote sensing and portable devices with limited power sources. Therefore, like the authentication methods for VQ and JPEG compressed images [3][4][5][6], the investigation of authentication for AMBTC compressed codes has received much attention, and subsequently, a number of authentication methods [7][8][9][10][11][12][13] in this field have been proposed in the past few years. These methods adopt spatial-domain data embedding techniques [14][15][16][17][18][19] or AMBTC-based compressed domain data hiding methods [20][21][22][23] to embed authentication codes (ACs) for the purpose of authentication.…”

Since digital media is gaining popularity nowadays, people are more concerned about its integrity protection and authentication since tampered media may result in unexpected problems. Considering a better media protection technique, this paper proposes an efficient tamper detection scheme for absolute moment block truncation coding (AMBTC) compressed images. In AMBTC, each image block is represented by two quantization levels (QLs) and a bitmap. Requiring insignificant computation cost, it attracts not only a wide range of application developers, but also a variety of studies to investigate the authentication of its codes. While the existing methods protect the AMBTC codes to a large extent, the leakage of some unprotected codes may be insensitive to intentional tampering. The proposed method fully protects the AMBTC codes by embedding authentication codes (ACs) into QLs. Meanwhile, the most significant bits of QLs are symmetrically perturbed to generate the candidates of ACs. The ACs that cause the minimum distortion are embedded into the least significant bits of QLs to minimize the distortion. When compared with prior works, the experimental results reveal that the proposed method offers a significant sensitivity-of-tamper property while providing a comparable image quality.

“…But reference data can be destroyed by some image processing operations, such as filtering, compressing and additional noise interference, so content recovery is disabled. A different method was proposed recently by Wu [49] where an image authentication scheme was proposed to exploit QR codes to protect the integrity of significant VQ authentication data. This method only focuses on the authentication process while the recovery process requires repetition until all blocks undergoing changes are reconstructed.…”

“…Grouping is different in Table 2 using the frequency domain. Method [4,41,49,54] take advantage of robust watermarking for generating recovery bits inserted into the LL sub band on the DWT. The main drawback of this method is that computing is quite high and the watermark insertion capacity is low.…”

The rapid developments of storage technology and information exchange encourage the development of research in the field of information security. In the process of sending information, tamper and issues about data ownership may occur. The fragile watermarking is one technique that can overcome the problem, in which this technique exploits sensitivity to tamper with the inserted watermark components. Therefore, it is not tolerable to change even only one bit. Self-embedding can be defined as some important features obtained from a selected image as a watermark by modifying the pixel value of the original image. Once a picture which has been inserted with a watermark is modified by other users, it can be used for tamper detection and recovery images. Due to the importance of this fragile watermarking scheme, this paper discusses the principles and characteristics of a fragile watermarking algorithm. The main contribution of this paper survey is that it summarises the current mechanisms of selection, generation, method of watermark insertion, detection and tamper localisation and recovery procedures. Comparison of several watermarking techniques was analysed and presented in tabular form, as well as experimental evaluation of four watermarking schemes in many graphs to show the performance of the self-embedding fragile watermarking scheme.

“…In the second step the unit circle within the stable edge profile is notified. [16](Wen-Chuan Wu, 2017) have proposed a digital image watermarking technique known as quantization-based image authentication scheme using QR error correction. The proposed scheme is mainly based upon quantization-based image authentication scheme using twodimensional barcodes mainly to protect important features.…”

This paper presents a digital image watermarking scheme comprising of DWT transformation. Due to the common practice of creating the copy, transmitting and spreading the data duplication of the original data occurs. Digital image watermarking has the ability to provide a solution for the unauthorized duplication problem. The scheme designed and presented in this paper comprises of mainly two modules one for embedding the watermark within the cover image and another for retrieving the watermark from the watermarked image. The process is carried out at different levels of the DWT transformation within different sub-bands of the DWT transformation. The extraction process involves the extraction of the watermark image form different channels of the RGB image mainly red, green and blue. The robustness and imperceptibility are tested. In each of the case, the corresponding PSNR and correlation values are noted and the results obtained concludes the scheme as the robust, semi-fragile and fragile digital image watermarking at different levels of the DWT transformation
