Abstract :
We present method that uses digital video watermarking as a real-time authenticator in a video stream. The proposed scheme uses the Hadamard transform as the spreading transform for the key, hence very fast coding and decoding of the the imperceptible watermark is realized. This in turn, can serve to verify the source of a digital frame in real-time.
