A video watermarking scheme is proposed in this paper using the concept of the secret sharing scheme. The owner's mark is split into twin shares, where the shares are inserted into the video frames in the spatial domain in a simple manner. The detection algorithm uses a linear function applied to the twin shares to reconstruct the secret. This makes the watermarked video sequence robust against pirate attacks, such as frame averaging and frame swapping. Due to the compatibility of the exploited secret sharing scheme to geometrical distortions, the watermarking system is also robust to this kind of processing schemes. On account of insertion of various marks into different frames, which are linearly related, the watermarked sequence is robust to collusion attack that is a major concern in the field of video watermarking.
