Color Image Steganography with Double Encryption
Bowsiya Begum M, D Selvamary · 2015
Cryptography is the science of using mathematics to encrypt and decrypt data and Steganography is the art of hiding data behind cover data. Combination of cryptography and steganography provides enhancement in data security i.e, forms a new security system. In this paper we have used double encryption using RSA algorithm and OPAP method is used for steganography this sort of encryption and stego-processing results in highly secured data transmission .the comparison between original & stegnoencrypted image is also done by using the image quality metrices such as MSE & PSNR.
