TLDR
A web based image authentication method based in digital watermarking can provide more controls to image owners and conveniences to clients who want to get authenticity of image by integrating benefits of using Internet to the watermark system.Abstract:
The demand of security is getting higher in these days due to easy reproduction of digitally created multimedia data. Digital watermark is the emerging technique to embed secret information into content for copyright protection and authentication. Watermark is embedded within an image that alteration and modification to the watermarked image can be detected in a fragile watermark system. Watermark detection is blind that does not require an original image and it is invisible to avoid revealing secret information to malicious attackers. A web based image authentication method based in digital watermarking is described in this paper. It can provide more controls to image owners and conveniences to clients who want to get authenticity of image by integrating benefits of using Internet to the watermark system.read more

Reversible dynamic secure steganography for medical image using graph coloring
TL;DR: A novel steganography technique that conceals patient information inside a medical image using a dynamic key generated by graph 3 coloring problem is proposed, which ensures reversibility as the original medical image is restored after extracting the embedded data from the stego medical image.
