A lossless blind image data hiding scheme for semi-fragile image watermark

International Journal of Computational Vision and Robotics (IJCVR), Vol. 10, No. 5, 2020

Abstract: In this work, we propose a digital watermark approach that is invariable to rotation and guarantees the integrity of the inserted mark. The size of the resulting image is identical to the original image and the process guarantees acceptable transparency. For this, we have experimented eight substitution processes to conclude that the substitution of four bits gives a great capacity of insertion while guaranteeing an acceptable transparency for the insertion of text. However for the insertion of an image, it is recommended to substitute only one bit. This reduces the capacity but guarantees transparency of the watermarking process.
