Description: 用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，-Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images, Platform: |

Description: If you re wondering about the number 7 on the equation, the watermark is inserted every 7 pixels. Why not in every pixel? You could, but this way, you can add a second watermark (and a 3rd, and a 4th, etc.) at the same time using the pixels in between (not scripted here yet). And the insertion process is complete. The new image is saved as a bitmap format (.bmp) which saves the data as it is, without any compression whatsoever. Platform: |

Description: Nowadays, with the rapid growth in formation technology more and more images and data are available on the internet. So there is a need to provide some kind of authentication to such important data. When the sender transmits the image to the receiver, there may be intruders present in between who may capture the image. After capturing the image the mage the intruder may view the meaningful content in the image. This may not be the problem in some cases. But if we consider security applications like medical and military images then such distortion is unacceptable. To avoid misuse or loss of information several reversible data hiding techniques (RDH) are implemented. This paper gives details on watermarking, LSB, Histogram and RDH using optimum Thresholding with related results.-Nowadays, with the rapid growth in information technology more and more images and data are available on the internet.
