Abstract :
This paper presents a fragile, blind and erasable watermark with low video quality degradations, the watermarking is done after the H.264 compression process. The framework computes a watermark, embeds the watermark and generates a new H.264 bit stream. The payload of the watermark consists of the encrypted hash value and a certificate with the public key. Some skipped macroblocks of the H.264 video are used to embed the watermark. The result of the framework is a new watermarked H.264 bit stream.
