Shailendra M. Pardeshi, Bharti D. Patil, Vipul D. Punjabi . A Survey on Novel Visual Cryptographic Steganography Techniques. National Conference on Emerging Trends in Information Technology. NCETIT, 2 (December 2014), 16-19.
The steganography and cryptography are the secret writing techniques. Steganography hides the existence of message by embedding data in some other digital media like image or audio format and Cryptography converts data in to cipher text that can be in unreadable format to normal user. This paper can concentrate to make review of combine data hiding techniques useable for security of data. This paper can defines RSA algorithm for encryption and embedded encrypted data in an image using DCT based steganographic technique. The DCT based technique is better than the other techniques like LSB, Modulus arithmetic steganography.
