摘要:In the cryptographic steganography system, the message will first be converted into unreadablecipher and then this cipher will be embedded into an image file. Hence this type of system willprovide more security by achieving both data encoding as well as data hiding. In this paper wepropose an advanced steganocryptic system that combines the features of cryptography andsteganography. In this proposed steganocryptic system we will encrypt the message into cipher1by using Kunal Secure Astro-Encryption and we again encrypt this cipher to cipher2 by usinggrid cipher technique. Advantage of Kunal Secure Astro-Encryption is that it generates randomuseless points in between, thus fixed size messages can be generated providing more securitycompared to other cryptographic algorithms as the number of characters in original messagecannot be found from encrypted message without the knowing the black holes. Now we willembed this cipher2 into image file by using visual steganography .In this proposedsteganocryptic system we will use modified bit insertion technique to achieve visualsteganography. This proposed system will be more secure than cryptography or steganographytechniques[digital steganography] alone and also as compared to steganography andcryptography combined systems.
