在传统扩频水印技术的基础上，我们讨论了一种基于相位偏移的非对称数字水印方案。

Based on traditional spread-spectrum watermarking, we discuss an asymmetric watermarking scheme using random-phase-shift.

而许多实际的应用都要求非对称的数字水印方案，即水印嵌入时使用私人密钥，水印检测时只需要一个公开密钥。

However, in many applications it needs an asymmetric scheme, where a private key is used for watermark embedding, and a public key is used for watermark detection.
