Abstract

Aiming at the need of personal privacy protection in the image acquisition system, paper proposes a video security algorithm used in facial protection. It fixes on the facial area in the image by face detection algorithm, regards facial area image as characteristic watermark information (large capacity watermark) and embeds them into the original image using large capacity color image watermarking algorithm, then encrypts the facial area to achieve the need of face protection. Ultimately, experiments use numerous test images to show the proposed algorithm has favorable compatibility and robustness. The algorithm is effectively united by face detection, watermarking, and encryption, having the obvious value on theory and application.
