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

Hybrid digital-embedding using invisible watermarking
TL;DR: The proposed technique for embedding a bi-color handwritten signature image of 70 times 50 pixels size in the color host image of 512 times 512 pixels shows very low visible distortions in the host image and algorithms provides high degree of robustness.

Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.

Exploring steganography: Seeing the unseen
Neil F. Johnson,Sushil Jajodia +1 more
TL;DR: It is argued that steganography by itself does not ensure secrecy, but neither does simple encryption, and if these methods are combined, however, stronger encryption methods result.

A robust content based digital signature for image authentication
Marc Schneider,Shih-Fu Chang +1 more
TL;DR: The idea of signature based authentication is extended to video, and a system to generate signatures for video sequences is presented, which allows smaller segments of the secured video to be verified as unmanipulated.
