Abstract :
Blind source separation (BSS) is explored to add another encryption level besides the existing encryption methods for image cryptosystems. The transmitted images are covered with a noise image by specific mixing before encryption and then recovered through BSS after decryption. Simulation results illustrate the validity of the proposed method
