摘要
Abstract
Digital watermarking technology, as a branch of informaiton hiding, is one of the hottest research topics in the information age. The implementation of digital audio watermarking is more difficult than traditional methods because of the sensitivity of human auditory system (HAS). It dicusses the research and implementation on a DCT domain digital audio watermarking algorithm based on quantization, in which the author introduced logistic-map encryption technique and quantization method to the traditional DCT domain digital audio watermarking algorithm to effectively improve the transparency, security, and robustness of watermarks.关键词
