Associated article: Audio Watermarking

Tags: Security     Web Development          Design    

Published source code accompanying the article by Michael Arnold in which he examines digital watermarking--a security technique that provides copy protection, authentication, and more for audio and other forms of information. The approach Michael presents here--implemented in Matlab--is based on a statistical algorithm working in the Fourier domain. Also see WATERMK.ZIP.
