dc.description.abstract The increasing sophistication of computers has made digital manipulation of photographic images (as well as other digitally-recorded artifacts, such as sound and video) incredibly easy to perform and, as time goes on, increasingly difficult to detect. Today, every picture appearing in newspapers and magazines has been digitally altered to some degree, with the severity varying from the trivial (cleaning up "noise" and removing distracting backgrounds) to the point of deception (articles of clothing removed, heads attached to other people's bodies, the complete rearrangement of city skylines). As the power, flexibility and ubiquity of image-altering computers continues to increase, the well-known adage that "the photograph doesn't lie" will continue to become an anachronism. A solution to this problem comes from the proposed Digital Signature Standard (DSS), which incorporates modern cryptographic techniques to authenticate electronic mail messages... en_US
