ABSTRACT
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.

Recommendations
Digital speech watermarking to enhance the security using speech as a biometric for person authentication
This work presents the modules for enhancing the security of speaker authentication by embedding the watermark in a speech signal. Speaker is authenticated by speech as well as the extracted watermark from the watermarked speech. Firstly, the speech ...
Multi-factor authentication model based on multipurpose speech watermarking and online speaker recognition
In this paper, a Multi-Factor Authentication (MFA) method is developed by a combination of Personal Identification Number (PIN), One Time Password (OTP), and speaker biometric through the speech watermarks. For this reason, a multipurpose digital speech ...
Hybrid Speech Watermarking Based on Formant Enhancement and Cochlear Delay
IIH-MSP '14: Proceedings of the 2014 Tenth International Conference on Intelligent Information Hiding and Multimedia Signal ProcessingIllegal use of digital technologies has brought a series of problems in speech protection and authorization. Digital watermarking can effectively solve these problems by embedding watermarks into the host signals. This paper proposes a hybrid ...
