Title
Spread-spectrum audio watermarking: requirements, applications, and limitations.
Abstract
Watermarking has recently been adopted as a technology of choice for many applications related to e-commerce of audio content. We present a brief summary of a set of spread-spectrum watermarking techniques for effective covert communica- tion over an audio signal carrier. Watermark robustness is enabled using redundant spread-spectrum for prevention against de-synchronization attacks. We improve wa- termark inaudibility by detecting and not watermarking blocb of audio where a spread spectrum sequence, if added to the frequency spectrum, would be audible. Finally, we overview the security limitations of our technology with respect to parameter selection and position it with respect to three main applications of watermarking: (U) content screening, (b) tracing unlicensed content distribution, and (c) robust metadata.
