Multiple Watermarking for Compressed Sensing with Robust Transmission Applications

摘要

Compressed sensing (CS) is a new research branch in multimedia compressing, which is famous for its superior performance. Due to its digital nature, it is easy to copy and distribute the compressed files in digital format, and the issues relating to digital rights management (DRM) applications would be in urgent need. We propose to hide multiple watermarks in compressed sensing coefficients. Color images consisting of three color planes with high correlations are selected for watermark embedding. Multiple watermarks are embedded into the CS coefficients corresponding to different color planes. With our method, watermarked images are suitable for transmitting over lossy channels, while the copyright of color images can be retained. Simulations have presented the effectiveness for the proposed algorithm.
