SARI - A Self Authentication and Recovery Image Watermarking System

(Online Demo and Download: http://www.ee.columbia.edu/sari)

Sari is a unique image/video authentication system that is able to distinguish malicious attacks of images from acceptable manipulations such as JPEG, Motion JPEG, or MPEG lossy compression. This site provides Java-based client software for extracting image signatures and watermark embedding on client sites. Users may send the watermarked images to the authenticator server at the server site to verify the authenticity of the images, or even recover the corrupted areas if forgeries are detected.
