摘要
零水印方法是一种新的数字水印方法。本文介绍了零水印的概念及零水印技术的关键问题,提出了一种基于时间戳认证的零水印方案。该方案很好地解决了非零水印的不可见性与鲁棒性之间的矛盾,具有可行性和通用性。
The zero-watermark method is a new digital watermarking method. The concept of zero-watermark and the core problem of zero-watermark technology are introduced in the paper. At last, a zero-watermark scheme based on time stamp authentication is proposed, which solves the contradiction between invisibility and robustness, and has commonality and feasibility.
