Abstract

The invention discloses a monitoring upper wall system with encrypted watermark, including a main control unit, a watermark image generating unit, a storage unit, a database module, Network Modules and Decoders. The watermark image generating unit, the storage unit, and the database module are respectively connected with a main control unit, the main control unit is connected with a network modulethrough a dot matrix server, A decoder is bidirectionally connected to the network module. The invention has simple working principle, After the watermark is generated by the dot matrix server and the watermark graphic generating unit, the watermark is superposed on the video monitoring, so that the purpose of tracing the source can be achieved when the illegal video is filmed, the problem of tracing the source of the illegal video is solved, and the user can quickly find the source and the responsible person of the image leakage.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a monitoring wall-mounting system with an encrypted watermark. Background technique [0002] The application of video surveillance is becoming more and more popular in today's society, covering every corner of the city and various facilities. Video security has also increasingly become a topic of concern, closely related to people's lives, and the issue of personal privacy has gradually emerged. [0003] At present, video surveillance shows that there are basically no encryption methods for various video surveillance images, and there is no research and development by professional institutions. However, video users are gradually increasing, and video applications are becoming more and more widely used in public security, transportation, prisons, urban management, communities, schools, enterprises and institutions. With the improvement of urban intelligent management, t...
