Description: 该水印算法具有以下特点：1）结合音频自身的特性，不仅能够自适应划分音频数据段，而且能够智能调节水印嵌入强度，增强了数字音频水印的鲁棒性；2）能够同时进行数字音频的版权保护与内容认证，并可大致确定篡改发生区域，仿真实验表明，文中算法不仅具有较好的不可感知性，而且对常规处理具有较好的鲁棒性，同时能够对替换等而已篡改做出报警并确定被篡改位置。-The watermarking algorithm has the following characteristics: 1) combined with the audio of its own characteristics, not only adaptive division of the audio data segment, but also can adjust watermark embedding intelligent strength, enhanced digital audio watermark robustness 2) can at the same time digital audio copyright protection and content authentication, and can generally determine the tampering occurred in the region, simulation experiments show that the algorithm not only has better not be perceived, but also on conventional treatment has good robustness, at the same time be able to tamper with it to make replacement alarm and to determine the location has been tampered with.
