Title: METHOD AND APPARATUS FOR AUTHENTICATING VIDEO CONTENT
Abstract:
A method for authenticating video content includes: receiving a digital signature, an unsecured video fingerprint, and an unsecured video content from a transmitting node at a receiving node in a communication network; determining if the digital signature is consistent with the unsecured video fingerprint at the receiving node to verify the unsecured video fingerprint; and determining if the unsecured video fingerprint is consistent with the unsecured video content at the receiving node to verify the unsecured video content in a manner that tolerates a predetermined measure of loss in the unsecured video content. If the unsecured video fingerprint and the unsecured video content are verified, the unsecured video content is authenticated for subsequent use at the receiving node. A receiving node associated with the method includes an input module, a fingerprint verification module, a content verification module, and a controller module.
