Capacity of Multiple Watermarks System

摘要：

Multiple watermark technique is a useful tool to solve the problems of multiple ownership or copyright. CDMA (Code Division Multiple Access) is a possible method to implement multiple watermarks embedding. The properties of CDMA just satisfy the requirement of multiple watermarking algorithms. In this research, capacity of multiple watermarks system is analyzed based on CDMA capacity theory. When two watermarks are embedded in an image at the same time, the capacity is larger than the capacity when the single watermark is embedded, and is smaller than the sum of the capacity of two watermarks are embedded respectively.
