Detection of Tampering in Color Image

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In the last few years there is a tremendous development in the area of high quality digital camera technology. So our life is full of the use of these digital images. However now a days there are lot of software (for example Photoshop, Photoscape, Photoplus and Picasa etc.) that can be used to modify these digital image. Therefore we cannot use these images as a proof or evidence. Therefore detection of tampering in image is important issue for forensic department. In this paper I have presented a method which is based on digital watermark for detection of tampering in image. In this method I have first embed a digital watermark in Least Significant Bit of pixel which is computed from digital content of image. My proposed algorithm consists of two parts. First is generation and embedding of digital watermark and second is detection of tampering and localization.
