A Binary Pattern Based Secure Data Hiding in Digital Images
Abstract
Information security is one of the most challenging tasks in the recent era of advanced technologies and communication. It is important to ensure the secure exchange of confidential data. Data hiding techniques have a key role in ensuring security. The proposed technique is one such technique to enhance the security of secret information by many folds. The proposed technique detects a binary pattern to classify the cover image pixels into two groups of pixels, i.e., the group of pixels used for information hiding and the group of pixels that remains unaffected. The secret information is hidden in the selected pixels using LSB substitution without creating any detectable modifications. The results show that the technique creates a high-quality stego image with a PSNR larger than the threshold level of 30dB and SSIM higher than 0.9999. Along with the good quality of the stego images, the binary pattern enhances the security of the hidden information twofold.
