Nowadays most of the multimedia contents are in digital form. With the increased use of powerful computer and image processing software, along with wide availability of digital cameras have given rise to huge numbers of doctored images. Several forgery detection algorithms are available. However, these techniques do not address the issue from cryptographic point of view. As a result, even if an image or video is identified as doctored, most of the time it is not possible to track the actual offender. Here, we present a perceptual hash function which can be used for both detection of forged images as well as tracking of forgers.
