Dual-Image-Based Pixel Pairing Reversible Data Hiding Technique

Reversible data hiding can be used in several applications where the recipient side requires the image and the secret data in their original, unaltered states. In this research, we present a novel reversible data hiding method based on the modification of the least significant bit (LSB). It modifies the LSB bits depending on the secret bits rather than replacing the LSB bits with the secret bits. It offers a comparatively high PSNR value and recovers both the original image and the secret data in their original forms for a single bit per pixel of data hiding.
