SECVISION Intelligent Building Video Surveillance Anti-Leakage Security Analysis
The integrated security management of intelligent buildings is a set of "integrated", "digital" and "intelligent" platforms, including multiple subsystems such as video, alarm, access control, and parking lots. It adopts advanced software and hardware development technology to solve the problems of centralized system management, multi-level networking, information sharing, interconnection and multi-service integration. Using high-definition network cameras, imaging 24 hours a day, real-time monitoring of the safety status of the building indoors, elevator cars, elevator halls, safety passages, outdoor intersections, perimeters, entrances and exits, basements, roofs and other areas; high-definition faces can also be used as needed The capture machine realizes the functions of intelligent face recognition, capture, storage, comparison, and retrieval; however, after intelligent data collection, there are a lot of hidden dangers in the security of data storage, transmission, and retrieval . Video access and video leakage prevention are still There are many problems and needs .
①Demand for online statistical asset management of cameras
②For monitoring indoor video data anti-recording screen capture, illegal copy video anti-leakage requirements
③Requirements for camera and other equipment access and video review and audit
The basic technical requirements of the Shanghai video security monitoring data export anti-leakage system stipulates the overall requirements, composition and basic functions of the video security monitoring data export anti-leakage system (hereinafter referred to as the "anti-leakage system") adopted in the city's video security monitoring system. It is one of the main technical basis for the design, compilation, installation and testing of related products. This requirement applies to video security monitoring system in local and remote video monitoring data derived anti-leak system - Shanghai anti Kogi (2014) 003.
Li EC SECVISION video anti-leak system consists of SECVISION video gateway anti-phishing and supporting client software, video gateway anti-phishing support for video overlay two-dimensional code watermark, the watermark dominant character, recessive watermark information is easy to record video, take pictures When it is leaked and spread by means of screenshots, screenshots, etc., trace the source of the screen content. The client software is installed on the video access terminal and automatically enforces encryption of all opened video files and restricts video downloading and copying operations.
① video behavior audit: vertical integration SECVISION video for anti-leak system can play video recording, playback, control, audit download behavior analysis and other operations, from distribution behavior, trends, operating logs and other two dimensions audit, and the audit The information is aggregated and displayed on the security visualization and situational awareness platform.
②Video encryption: It can transparently encrypt the outgoing video data, and can set the password, open time, limit number of times, print, watermark and other permissions for the encrypted video file. Watermark encryption and video fingerprinting (loaded frame by frame during video transmission)
③ watermark function: SECVISION video anti-leak system supports two-dimensional code watermark, the watermark dominant character, recessive watermark ; where the hidden watermark technology based on innovative reuse code have implemented algorithm, the human eye can perceive the information easy The image details are separated to achieve the effect of a secret watermark. Video outsourcing approval, encryption, and traceability management .
