JOINT ENCRYPTION WATERMARKING SYSTEM USING AES AND RC4
This project design is based on the joint encryption/watermarking system for the purpose of protecting medical images. This system is based on an approach which combines a substitute watermarking algorithm, the quantization index modulation, with an encryption algorithm: a stream cipher algorithm (e.g., the RC4) or a block cipher algorithm (e.g., the AES in cipher block chaining (CBC) mode of operation). Our objective is to give access to the outcomes of the image integrity and of its origin even though the image is stored encrypted. If watermarking and encryption are conducted jointly at the protection stage, watermark extraction and decryption can be applied independently. The security analysis of our scheme and experimental results achieved on medical images. The two algorithms performance is evaluated with PSNR and MSE values.
