Reversible Watermarking Scheme with Image-independent Embedding Capacity
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems, such as salt-andpepper artefacts due to intensity wraparound and low embedding capacity, can now be resolved. However, we point out in this w...
متن کاملVery High Embedding Capacity Algorithm for Reversible Image Watermarking
Reversible image watermarking enables the embedding of copyright or useful information in a host image without any loss of information. Here a novel technique to improve the embedding capacity i.e. reversible watermarking using an adaptive prediction error expansion & pixel selection is proposed. This work is an improvement in conventional Prediction Error Expansion by adding two new techniques...
متن کاملContent-independent embedding scheme for multi-modal medical image watermarking
BACKGROUND As the increasing adoption of information technology continues to offer better distant medical services, the distribution of, and remote access to digital medical images over public networks continues to grow significantly. Such use of medical images raises serious concerns for their continuous security protection, which digital watermarking has shown great potential to address. ME...
متن کاملAdaptive reversible image watermarking scheme
This paper presents an adaptive block sized reversible image watermarking scheme. A reversible watermarking approach recovers the original image from awatermarked image after extracting the embedded watermarks.

متن کاملA Multiple Image Based Reversible Data Hiding Scheme with High Embedding Capacity
In recent years, reversible data hiding methods using dual stego images have been proposed extensively. In order to embed more secret data, we proposed a reversible data hiding method that can embed secret data into M stego images, where M ≥ 2. The pixel in M stego images can be used to embed N secret bits. The embedding capacity becomes greater as N and M increase, where N means the number of ...
