A Survey on Watermarking and Reversible Medical Image Watermarking Techniques

Image authentication has drawn a good attention in both storage as well as communication, with the advancement of technology on the internet. Enforcement of protection of medical content that is being transmitted through the internet also has become a major issue of computer security. Since medical contents are more widely distributed, it is necessary to develop security mechanism to guarantee ...

FPGA Implementation of Image Adaptive Watermarking Using Human Visual Model

Abstract In this paper we describing blind, robust and computational efficient algorithm in DHT (Discrete Hadamard Transform) domain. The algorithm was developed using the human visual system (HVS) based on DHT. This allows embedding the watermark with maximum gain factor within the imperceptible regions of the image. The algorithm was implemented on FPGA (Field Programmable Gate Array) and tes...

FPGA Based Implementation of an Invisible-Robust Image Watermarking Encoder

Both encryption and digital watermarking techniques need to be incorporated in a digital rights management framework to address different aspects of content management. While encryption transforms original multimedia object into another form, digital watermarking leaves the original object intact and recognizable. The objective is to develop low power, real time, reliable and secure watermarkin...

Stereo Image Reversible Watermarking

In this paper, a new reversible watermarking method is presented that reduces the size of a stereoscopic image pair while keeping its content visible. The proposed technique embeds the disparity compensated difference and the disparity vectors of the stereo pair into the reference image, halving its total capacity. The residual is usually lossy compressed before embedding because the embedding ...

Improved Tian’s Method for Medical Image Reversible Watermarking

Fragile watermarking techniques ensured content authentication and tamper proofing but the permanent embedding distortion is intolerable in the medical field even it is imperceptible. The most adequate solution for this problem is the reversible watermarking. In this paper, we started by giving a short overview of some reversible watermarking techniques to pass thereafter to present an improvem...
