Watermarking for Compressive Sampling Applications

Abstract

Compressive sampling is a newly developed topic in the field of data compression. For current researches, compressive sampling techniques focus on compression performances. There are very few papers aiming at the integration of watermarking into compressive sampling systems. In this paper, we propose an innovative scheme that considers the copyright protection of data with compressive sampling. By carefully utilizing the relationships between coefficients, very few amounts of transmitted coefficients are capable of reconstructing the image to some extent. Moreover, secret information embedded beforehand can be recovered with acceptable rate in correctly extracted bits even experiencing through the lossy channels for data delivery. Simulation results with our algorithm have demonstrated the effectiveness for integrating watermarking into compressive sampling systems.
