A New Scheme for Lossless Meaningful Visual Secret Sharing by using XOR Properties [PDF]
In this paper, a novel scheme for lossless meaningful visual secret sharing using XOR properties is presented. In the first step, genetic algorithm with an appropriate proposed objective function created noisy share images.

A contrast-sensitive reversible visible image watermarking technique [PDF]
A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

A secure lossless recovery for medical images based on image encoding and data self-embedding [PDF]
To protect the security of data outsourced to the cloud, the tampers detection and recovery for outsourced image have aroused the concern of people. A secure tampering detection and lossless recovery for medical images (MI) using permutation ordered binary (POB) number system is proposed.

Reversible watermarking scheme with image-independent embedding capacity [PDF]
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,

Reversible Data Hiding Scheme in NTRU Encrypted Domain Based on Polynomial Partition [PDF]
With the rapid development of cloud computing techniques and demand of privacy preservation,reversible data hiding(RDH) in homomorphic encrypted domain has become a hot research topic.Most of the existing RDH schemes in encrypted domain exploit ...

Lossless Snubber Cell for a Soft-Switched Bidirectional Buck–Boost Converter
In this paper, we propose a lossless snubber cell for a soft-switched bidirectional buck-boost converter (BBC). The proposed snubber cell provides all switches with soft-switching conditions in both the bidirectional power flows of the BBC.

Adaptive Unified Data Embedding and Scrambling for Three-Dimensional Mesh Models
Traditionally, unified data embedding and scrambling techniques have been designed for grayscale images, which cannot be applied directly to a three-dimensional (3D) mesh. Recently, the universal use of 3D technology inspired us to innovate in this field.

Practical Secret Image Sharing Based on the Chinese Remainder Theorem
Compared with Shamir’s original secret image sharing (SIS), the Chinese-remainder-theorem-based SIS (CRTSIS) generally has the advantages of a lower computation complexity, lossless recovery and no auxiliary encryption. However, general CRTSIS is neither
