Audio watermarking algorithm for real-time speech integrity and authentication
Yuan Jia Song, Sorin Alexander Huss · 2004
Data integrity and source origin authentication are essential topics for real-time multimedia systems. But traditional method, such as MAC, is not very applicable to overcome the distortion introduced in real-time multimedia communication. In this paper a new integrity mechanics deploying speech watermarking is presented. The advocated approach adopts public key encryption to efficiently generate non-repudiate speech. In the last part of the article, a speech watermarking algorithm incorporating with GSM 610 full-rate coder is proposed.
