Abstract：It proposes an audio tamper detection algorithm based on dual watermark. It uses binary image as the watermark signal by reducing the image dimension. By appropriate subparagraph, the signals are embedded into the audio averagely so to generate content authentication watermark. Using the binary digital string of section number, the integrity watermark is generated so to implement audio content authentication and copyright protection. By extracting the watermark and comparing with the original watermark, it determines the audio integrity and locates the tamper region precisely. Simulation results show that this algorithm has good imperceptibility and high accuracy to audio tamper detection.
