Abstract
A secure method and apparatus for compressing and digitally signing compressed video data. The apparatus compresses video data and permits signing of the compressed video image in such a way that if only a portion of the video image is successfully transmitted, the digital signature corresponding to that portion can still be verified. An optimization scheme which allows the verification of portions of a successful digital transmission with using only one digital signature is also disclosed.
