document: Blind source separation applied to image cryptosystems with dual encryption Blind source separation -LRB- BSS -RRB- 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
