Example Embodiment

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

[0019] Attached figure 1 Describes the basic process of processing video data. First, the original video data is collected through the camera; then the collected data is encoded in real time, and the digital watermark is embedded at the same time as the encoding to ensure the security and reliability of the data. The encoded video data of the watermark; the encoded video data can be stored and transmitted; when needed, the encoded 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 Describes watermark embedding during video encoding, with image 3 Describes the extraction of watermark during vide...

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...
