Secure and Efficient Image Hiding Method and Model for Digital Content Access Control

Abstract — This paper introduces a best approach for Least Significant Bit (LSB) based on image steganography that enhances the existing LSB substitution techniques to improve the security level of hidden information. It is a new approach to substitute LSB of RGB true color image. The new security conception hides secret information within the LSB of image where a secret key encrypts the hidden information to protect it from unauthorized users. In LSB methods, hidden information is stored into a specific position of LSB of image depending on the secret key. We have used the Peak Signal to Noise Ratio (PSNR) to measure the quality of the stego images. The obtained results show that the proposed method results in LSB based image steganography using secret key which provides good security issue and PSNR value than general LSB based image steganography methods.
