Image encoding and watermarking in the double random phase encoding scheme with sparse representation strategy

Abstract A novel method for image encoding and watermarking is proposed in this paper. It is shown that the security of the double random phase encoding (DRPE) scheme could be improved by watermarking the encoded image with a simple approach, which derives from the sparse representation strategy.
