摘要：

Digital Audio Watermarking techniques can be used as a lightweight security mechanism for source origin authentication in voice over IP (VOIP) systems. During the transportation phase of VOIP audio-marked voice packets are used as a source origin indicator. In this paper several audio watermarking algorithms were evaluated to demonstrate the applicability of the source authentication solution in terms of certain parameters such as: robustness, evaluation time, complexity and capacity. The effects of the audio watermarking were also measured using the Signal-to-Noise ratio and watermark extraction times. The evaluated VOIP codecs are: G711 a-law and u-law, GSM, G723.1 and ILBC.
