Embodiment Construction

[0018] The main feature of the present invention is that while the collected video data is encoded in real time, the digital watermark technology is used to embed identification information in the video data, thereby improving the security and reliability of the video data.

[0019] attached figure 1 The basic process of video data processing is described. Firstly, the original video data is collected through the camera; then the collected data is encoded in real time, and digital watermark is embedded at the same time of encoding to ensure the security and reliability of the data. The coded video data of the watermark; the coded video data can be stored and transmitted; when needed, the coded video data can be decoded and played, and the digital watermark can be extracted while decoding to ensure the security of the data and reliability.

[0020] attached figure 2 Watermark embedding in video encoding is described, with image 3 It describes the watermark extraction durin...

Abstract

The video acquisition method adopting digital watermark technology includes the following steps: acquiring video data; real-time encoding the acquired video data; and embedding digital watermark into video data while encoding the acquired video data. The present invention has wide application foreground in the video monitoring system for bank, traffic, etc. and the acquired video data have high security and reliability.

Description

technical field [0001] The invention relates to multimedia information security, in particular to a video collection method using digital watermark technology. Background technique [0002] With the rapid development of computer technology, video capture technology, especially digital video surveillance technology has been widely used in all aspects of our life and work, such as teller machine monitoring in the banking system, vehicle violation and flow monitoring in the traffic system , Residential security monitoring in daily life and so on. Video surveillance technology has great application value in aspects such as security protection, information acquisition and command and dispatch. [0003] The development of video surveillance system has roughly gone through three stages. The first generation is an analog monitoring system, mainly a closed-circuit television monitoring system based on analog equipment; the second generation is a digital local video monitoring syste...
