Digital Image Watermarking using LSB Technique
نویسنده
چکیده
Watermarking belongs to hide particular information, so that you can easily detect any tamper detection .It is used for confidenality, authentication and copy right protection. In this paper watermarking is done with the help of least significant bit technique (LSB).As LSB technique is used as it has less effect on image. This new algorithm is using LSB of original image and idoing ‘&&’ operation with MSB of watermark image, and same watermarked image is then extracted from host image by replacing its LSB with MSB and making its LSB zeroes, so then watermark is extracted from host image
