Abstract

In this paper, we introduce the technique of watermarking using least significant bit (LSB). Many researchers have done their research using LSB because of its affect on image. The research is using a new LSB to hide the data in images. The proposed algorithm inverse the binary values of secret data before embedding it. The proposed algorithm is flexible depend of the secret data. If length of the secret data is more than ((MxN)/8)-2 the proposed algorithm will also embed the extra of the secret data in the second LSB. The research approved its quality by comparing the result of the Peak signal-to-noise ratio (PSNR) of the proposed algorithm and the 1-LSB and Lee's algorithm. Also, we attack the watermarked image by using cropping and adding noise and we got good results.
