Based on an indepth study of watermarking and cryptography, a new monitoring and management program is proposed for monitoring the outdoor LED advertisement content. In this program, the watermark of copyright is bind for the advertisement content before frequencydomain encryption. Under the premise of ensuring the authoritativeness, fairness and practicality, the overall system security is improved and the legitimate rights of the advertising company is safeguarded. A content monitoring and management system of the outdoor LED advertisement is constructed based on the program. Through the establishment of a data center and a monitoring center, the system enhances the management of the outdoor advertisement prior to its broadcast, and the management of the actual content of the advertisement. The outdoor LED can only play the audited content, and perform video recording comparisons to prevent vulnerabilities.
Key words： watermarking;cryptography;content;monitoring
