Description: 数字水印的攻击方法和对策浅析电子书胡启明(武汉理工大学信息工程学院)摘要:在保护数字图像、视频、音频等数字媒体的知识产权方面,数字水印技术是一种很有前景的方法。由于作为版权标记的数字水印正面临着越来越多的攻击,对数字水印的稳健性要求也越来越高。笔者对4类不同原理的数字水印攻击:简单水印攻击、同步水印攻击 削去水印攻击和IBM水印攻击进行了详细论述,并给出了相应的解决对策。-digital watermarking method of the attacks and countermeasures of e-books Huo (Wuhan Polytechnic University, the Information Engineering Institute) Abstract : the protection of digital images, video, audio and other digital media in regard to intellectual property rights, Digital watermarking technology is a promising approach. Due to copyright labeled as digital watermarking is facing a growing number of attacks, Digital watermarking to the stability requirements have become more sophisticated. The author of four different types of digital watermarking principle of attack : simple watermark attack Synchronous watermark attack defrocked watermark attacks and IBM watermark attacks discussed in detail. and the corresponding solutions.

Description: This discussion will attempt to outline some truths and common misconceptions about digital audio watermarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.

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.
