Embodiment Construction

[0056] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0057] Aiming at the problem of video information security protection of network video monitoring service, the solution proposed by the present invention is to use a video data encryption method to encrypt the video data and then transmit it. The encryption key is dynamically generated by the video surveillance platform, and each video transmission is different, which further strengthens the encryption strength of the video and prevents the encryption key from being cracked violently. After the video data is transmitted to the destination, it is decrypted according to the decryption key. There are two types of video data encryption, key frame encryption and full data encryption.

[0058] The preferred implementation modes of the present invention will be described in detail below. In the followin...

Abstract

The invention discloses a video data encryption system and method of net video monitoring, including: a video monitoring platform (101), which generates encryption keys and confidential keys and distributes them to a net camera (102) and a video monitor terminal (103), a net camera (102), which collects and compresses live videos and sends video data to the video monitor terminal (103) after encrypting according the encryption key acquired from the video monitoring platform (101), and the video monitor terminal (103), which establishes a video transmission link to the net camera (102), decrypts the received video data according to the decryption key distributed by the video monitoring platform (101) and displays the video information. The invention realizes the encryption and protection to video monitored data.

Description

technical field [0001] The invention relates to network video monitoring technology, in particular to a system and method for video data encryption oriented to video monitoring under the Internet environment. Background technique [0002] Traditional video surveillance services, such as video surveillance services widely used in industries and departments such as finance, transportation, public security, water conservancy, and quality inspection, are mostly in closed LANs or private networks, and their networks are not open to the outside world. There is no need to consider the security and privacy protection of video data. And the video data of these occasions generally do not have the user's privacy. [0003] However, with the continuous development and improvement of modern communication technology and multimedia data encoding and decoding technology, surveillance cameras have gradually developed from analog and digital cameras to network cameras. The network environmen...
