In recent times, the movement of 3D movies and 3D projection took enormous attention. Anaglyph images are elementarily obtained by overlapping left and right eye images in different color planes of a single image for successive viewing through colored glasses. Digital watermarking is a desirable tool for copyright protection, secret communication, detection of illegal duplication and alteration and content authentication. Here Fractional Fourier transform (FrFT) watermarking algorithm is used for implanting a sequence or an image as digital watermark on one of the stereo pair images and then superimpose on the other image to build a 3D anaglyph watermarked image. In the counter process, De-anaglyph is used to detach the two stereoscopic images from which watermark is derived. Inserting watermark either in the right image or left image fetches more protection compared to embedding watermark straight into an anaglyph image.
