Fragile Audio Watermarking with Perfect Restoration Capacity Based on an Adapted Integer Transform

摘要：

　　In this paper,we propose a novel audio watermarking scheme which can recover the original audio carrier perfectly if the watermarked audio is modified.Besides,we can adjust the maximum tampered rate allowed and the quality of watermarked audio flexibly as needed.In the scheme,an efficient generalized integer transform is improved to embedding watermark data which are composed of LSBs of averages in each patch,reference-bits and check-bits.LSBs are needed in the inverse transform.Then,by comparing the extracted check-bits and calculated ones,modified area can be localized.Finally,reliable reference-bits and samples data help us reconstruct the original audio without error.The efficience of the proposed method is theoretically and experimentally verified.
