A new digital watermarking algorithm using combination of Least Significant Bit (LSB) and inverse bit
In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image. This new algorithm is using LSB by inversing the binary values of the watermark text and shifting the watermark according to the odd or even n...

| description | In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little
effect on the image. This new algorithm is using LSB by inversing the binary values of the watermark text and shifting the watermark
according to the odd or even number of pixel coordinates of image before embedding the watermark. The proposed algorithm is flexible
depending on the length of the watermark text. If the length of the watermark text is more than ((MxN)/8)-2 the proposed algorithm will also
embed the extra of the watermark text in the second LSB. We compare our proposed algorithm with the 1-LSB algorithm and Lee’s algorithm
using Peak signal-to-noise ratio (PSNR). This new algorithm improved its quality of the watermarked image. We also attack the watermarked
image by using cropping and adding noise and we got good results as well. |
