Robust coding of encrypted images via structural matrix

The robust coding of natural images and the effective compression of encrypted images have been studied individually in recent years. However, little work has been done in the robust coding of encrypted images. The existing results in these two individual research areas cannot be combined directly for the robust coding of encrypted images. This is because the robust coding of natural images rel...

Robust Watermarking of Compressed and Encrypted JPEG2000 Images: Overview

The need for copyright protection, ownership verification, and other issues for digital data are getting more and more importance nowadays. Among the solutions for these issues, digital watermarking techniques are used. A range of watermarking methods has been estimated. Compression plays a significant role in the design of watermarking algorithms. For a digital watermarking method to be effici...

Robust Watermarking of Compressed and Encrypted JPEG 2000 Images

In this paper we present a secure patient medical images and authentication scheme which enhances the security, confidentiality and integrity of medical images transmitted through the Internet. The medical images are secured using the digital image watermarking scheme. If any attacker try to access the secret medical images, that connection is immediately rejected. The proposed approach is used...

A Robust Zero-Watermarking Algorithm for Encrypted Medical Images in the DWT-DCT Encrypted Domain

Patients’ personal information contained in medical images can easily be intercepted and tampered with by unauthorized person when they are transmitted through the Internet. Therefore, it has latent risk of information leakage and should be seriously taken into account. Processing watermarking in the encrypted domain is a reasonable solution. The hybrid Discrete Wavelet Transform (DWT) and Disc...

A Robust Watermarking Algorithm for Encrypted Medical Images Based on DFT Encrypted Domain

Most of the existing robust watermarking schemes were designed to embed the watermark information into the plaintext images, which leads to a latent risk of exposing information and are vulnerable to unauthorized access. In addition, the robustness of watermarking in the encrypted domain is another issue that should be taken into account. Based on Discrete Fourier Transform (DFT) and Logistic c...
