Abstract(in Japanese) (See Japanese page)
Abstract(in English) The tampering detection method using digital watermarking in interrogation audio has a problem that many false positives occur due to the frame misalignment for tampering where the overall audio length is no longer frame by frame. In this study, a synchronization signal using an M-sequence as a random sequence is embedded in the audio, and the synchronization position is calculated and synchronized by cross-correlating the M-sequence used in the detection side and the audio with the synchronization signal, and the watermark is accurately detected. In an experiment conducted to confirm the effectiveness of the proposed method, we compared the accuracy of tampering detection without and with frame synchronization by applying insertion and deletion tampering to degraded speech assuming an operational environment. As a result, we were able to significantly improve the detection accuracy compared to the case without frame synchronization.
