Abstract
Steganography is the art of science of hiding information which is more useful in many social networks, digital media, and printing material. Many hiding algorithms are used to flourish the security level of the recent wireless multimedia system to protect the data from an attacker. This paper describes about existing steganographic based hiding methods using LSB techniques, RSA algorithm, DNA cryptography and DNA steganography, which is used to prevent copying, forgery and unauthorized access of videos, audios and images. Existing hiding methods had demerit of increased key size, computational cost, speed and size of the input. Thus the DNA steganography based Hyperelliptic Curve Cryptography (HECC) is proposed which provides a higher level of security to image file and also assure the digital media security. The proposed HECC based DNA steganography is compared with traditional cryptographic techniques results in 30 and 42 % increased processing time for encryption process and decryption process respectively. Finally, the proposed scheme is compared with other traditional steganographic technique in terms of Mean Square Error, Peak Signal to Noise Ratio (PSNR), embedding capacity. From the simulation results, it is inferred that, the proposed steganographic method has, the less embedding capacity, high MSR and PSNR value compared with other steganographic methods.
