摘    要:介绍了使用Wavelet过滤参数作为提高许多水印算法安全性的一种方法,并且这种依靠Wavelet过滤器的密钥的方法能很容易成为一种安全框架。本文还提供了一种新颖的水印算法,能适合独立的码组进程的新图像编号标准。两种应用脚本——版权保护和图像的真实性能够被认同,并且基于量子化的嵌入技术,可以成功地加密和解密在JPEG2000编码处理中高速运转的一个二进制水印。

关 键 词:数字水印  新颖  Wavelet  过滤器  参数  安全

Abstract:The article introduces using Wavelet filter parametrization as a means to improve the security of many previously proposed algorithms and demonstrates that the concept of secret key-dependent Wavelet filter can be easily employed as a security framework .The article also presents a novel watermarking scheme that is compatible with the independent code-block processing approach of the new image coding standard. Two application scenarios copyright protection and image authentication are considered and the article demonstrates that quanfization-based embedding technique can successfully encode and decode a binary watermark on-the-fly in the JPEG2000 coding process.
Keywords:digital watermark   novel   Wavelet   falter   parameter   secure
