This paper proposes a spatial domain based video watermarking scheme to improve security of the video data using a combination of modified LSB watermarking technique of spatial domain and a (n, n) secret image sharing scheme. In this scheme the secret image sharing scheme is applied during transmission right after the embedding of the watermark in the video frame to overcome the drawback of the single LSB technique. This combination ensures high security and robustness as the watermarked image is being distributed into 3 meaningless shares during transmission thus making it imperceptible to the attacker. This dual scheme improves the extraction capability of the secret message and enhances the information embedding capacity. The average PSNR obtained was 55dB which proves that the quality of reconstruction is high and higher than most of the existing watermarking techniques in similar domain.

Abstract


This paper proposes a spatial domain based video watermarking scheme to improve security of the video data using a combination of modified LSB watermarking technique of spatial domain and a (n, n) secret image sharing scheme. In this scheme the secret image sharing scheme is applied during transmission right after the embedding of the watermark in the video frame to overcome the drawback of the single LSB technique. This combination ensures high security and robustness as the watermarked image is being distributed into 3 meaningless shares during transmission thus making it imperceptible to the attacker. This dual scheme improves the extraction capability of the secret message and enhances the information embedding capacity. The average PSNR obtained was 55dB which proves that the quality of reconstruction is high and higher than most of the existing watermarking techniques in similar domain.
