Abstract

This chapter provides an overview of digital audio watermarking systems, including a description of recently developed watermarking algorithms and insights into effective attack strategies against audio watermarking methods. Audio watermarking algorithms are characterized by a number of defining properties, ranging from robustness requirements to computational complexity and cost of implementation. This chapter provides a comprehensive list of signal modifications that are usually used by adversaries in order to distort the embedded watermark and prevent detection of the hidden data. At the end, application areas that have recently been developed and possible future applications areas are listed.
