Abstract
The problem of lossy compression of encrypted image data is considered in this paper. A method is proposed to achieve compression of the encrypted image data based on compressive sensing technique. Joint decoding/decryption is proposed with the modified basis pursuit decoding method to take care of encryption. Simulation results are provided to demonstrate the compression results of the proposed compression method based on compressive sensing.
