Compressed domain secure, robust and high-capacity audio watermarking

摘要

Watermarking has attained wide consideration for copyright security of multimedia information. Audio watermarking scheme using discrete wavelet transform and singular value decomposition (SVD) along with encryption is proposed in this article. Transform domain coefficients undergo SVD and then utilizing Fibonacci numbers encrypted watermark data is inserted into the singular values to ensure achievable acquirement of watermark. Proposed algorithm utilizes chaotic and AES encrypted watermarks for embedding to accelerate the scale of security. High imperceptible attribute, robust nature and high payload are achieved using the proposed strategy. Experimental results show that the audio watermarking scheme is not only inaudible, but also robust against various common signal processing attacks such as noise addition, filtering,equantization, echo, invert and compression.
