A Novel Hybrid Image Hiding Technique using Elliptic Curve Cryptography and DNA Computing Technique

Abstract

The proposed novel hybrid image hiding techniques uses the security features of ECC for encrypting the secret image before embedding with cover image and also map the secret image with DNA nucleotide to improve the level of security with high embedding capacity. In the proposed image steganography, the secret image is fed as input to the ECC encryption algorithm and the resultant ciphertext point is mapped with DNA nucleotide, and then converts it into binary digits. Second, the cover image is compressed by using DWT compression techniques. The compressed image is used as a cover image to embed the secret image by using a singular value decomposition algorithm. The resultant stego image will have high PSNR and less MSE. Results show that 36.23% decreased value of MSE value and 5.6% increased value of PSNR for 512 × 512 image size.
