“…Five algorithms were implemented in their sequential form following their description reported in the literature. The algorithm proposed by Bravo-Solorio et al [27] was optimized using the MatLab parallel computing toolbox due to its very high time complexity. For each experiment, 2000 gray-level images from the BOWS 2 [34] data set were used; each image is 512 × 512 pixels in size.…”

“…Finally, the original grayscale values from all the pixels in the blocks identified as tampered are restored. The scheme by [27] proposes a secure block mechanism, resilient to content replacement attacks. To locate the tampered blocks, it uses the unaltered pixels and the reference bits to estimate the original five MSB of the altered pixels, using an iterative and exhaustive restoration mechanism.…”

Evaluation of a Framework for Robust Image Reversible Watermarking

In the literature, robust reversible watermarking schemes (RWSs) allow the extraction of watermarks after the images have suffered attacks; however, the modified images are compromised. On the other hand, self-recovery schemes will restore the compromised regions of the images, but no secret messages are inserted in these schemes. A framework for robust reversible watermarking with signal restoration capabilities was previously proposed in the literature. This study selects four fragile reversible watermarking techniques and two self-recovery schemes to design different framework configurations. These configurations are evaluated to test the framework’s performance and determine the structure that yields better results in terms of perceptual transparency using a well-known image database as the signal input. It was found that fragile reversible watermarking schemes hold low perceptual distortion, while self-recovery schemes produce high perceptual distortion levels. The inherent characteristics of each algorithm determine, a priori, the behavior of the framework, which is approximated by a proposed equation.

“…In [96] the scheme from [95] is improved, it can also reconstruct the image after content replacement attack as long as the tampered area is smaller than 24% of the image. In [97] a scheme that can perfectly reconstruct an image after cropping attack is presented, as long as the tampered area is smaller than 25% of the image. In [98] their previous approach from [97] is improved in terms of computational cost for tamper restoration.…”

In [98] their previous approach from [97] is improved in terms of computational cost for tamper restoration. This method, as well as the previous one performs the restoration of tampered areas in an iterative manner, where the first iterations yield approximate restoration, but as the iterations increase so does the restoration quality.…”

A Survey on Reversible Watermarking for Multimedia Content: A Robustness Overview

In recent years, the growth of the Internet along with multimedia data delivery, have caused the misuse and even alteration of the original digital content. As a security mechanism, digital watermarking has been used to protect digital content, traditionally in copyright protection applications, and more recently digital watermarking has been used in content enhancement applications. Regardless of the application, digital watermarking schemes always cause some level of signal degradation. There are however, certain applications as in the military or medical fields, where loss of information cannot be tolerated during the reconstruction of host signals, therefore conventional watermarking schemes do not satisfy the quality requirements. In order to reconstruct signals without loss of data, reversible watermarking is employed. Recent research in reversible watermarking has focused on either, the improvement of embedding capacity or the reduction of perceptual impact of the schemes, but scarcely exploring the robustness of reversible schemes. In this survey, we provide a deep review of reversible watermarking schemes and propose a new classification outline based on the robustness point of view. Finally, some future directions for reversible watermarking research are presented and open problems in robust reversible watermarking are outlined. INDEX TERMS Digital watermarking, multimedia content, reversible watermarking, robustness.

Today, the world is going to be digitalized in all the ways. Every business units, government and private sectors, research units are using the digital image as transferring mode for every critical data. These images over the internet which will not be secure. Therefore there is a need of image security. Currently, there exists various image security techniques like encryption, watermarking, steganography, etc. This paper discusses the basic image security techniques, the survey of the recent research in the field of image securities like ANN Based Approach, Genetic Algorithm Based Approach, DCT based approach, chaos-based approach, SVD based approach, Steganographic based approach, DWT based approach, visual cryptography based approach, watermarking based approach. The paper provides the future scope of image security.
