Abstract
Digital image watermarking techniques are suitable for integrity authentication, watermark security, and copyright protection. Further, the number of embedding bits and the process of watermarking also play a crucial role in deciding the effectiveness of any watermarking process. In this regard, to achieve better security without producing noticeable artifacts in the watermarked image, this paper proposes a dual image-based watermarking technique using an exclusive-or (XOR) operation. The proposed technique utilizes a modified least significant bit (LSB) substitution strategy in the host image (HI) pixel to substitute the watermark bits with a maximum of ±1 modification to each pixel. Each HI pixel embeds two watermark bits by producing two different watermarked pixels each. The proposed technique has better watermark bit embedding capacity, higher perceptual transparency, and security.
