摘要
A system and method are provided for facilitating the playing of a watermarked video having the “birthday problem”. Consumers send the problem disc to an authorization center where the disc is analyzed to determine if it is a legitimate disc. The authorization center generates a digital certificate uniquely associated with the disc and with the video and embeds the digital certificate into the disc. The digital certificate will cause a video player to play the video without checking for the watermark.
