Secure reversible data hiding technique on textures using double encryption

A data hiding technique using textures is proposed here. A texture synthesis method is used to resample a small texture image and creates a new texture image with similar appearance and random size. A discrete cosine transform method is utilized to hide the secret information during message oriented texture synthesis. And the embedding capacity offers is relative to the size of stego texture image. For security double encryption is performed on the secret information using Advanced Encryption Standard(AES) and Elliptic Curve Cryptography(ECC). And the message is then compressed using lossless compression method(LZW) before concealing into the selected location. Hence the residing capacity of secret information can be reduced. This technique enhances the security of secret data and improves the embedding capacity as well.
