Embodiment Construction

[0094] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0095] figure 1 It is a schematic structural diagram of a monitoring system supporting data encryption protection in an embodiment of the present invention. Such as figure 1 As shown, the system includes: front-end equipment, monitoring center and back-end equipment.

[0096] Among them, the front-end device is used to send the monitoring information collected and encrypted by itself to the monitoring center, and the monitoring center judges whether the back-end device is authorized to access the selected front-end device according to the access request of the back-end device to the selected front-end device. The monitoring information of the front-end equipment, if yes, sending the monitoring information of the selected front-end equipment to th...

Abstract

The invention relates to a method for protecting data encryption in a monitoring system. The method comprises the steps: only one identity key is arranged for each first device respectively; an encryption key corresponding to data information of the prior first device is obtained according to the identity key of the prior first device, the data information of the prior first device is encrypted by adopting the encryption key to generate the encryption data stream, and the encryption data stream is transmitted. In addition, the invention also discloses a monitoring system, a monitoring center and a first device for supporting data encryption protection. The technical scheme disclosed by the invention can enhance the security of the data information.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a data encryption protection method in the monitoring system, a monitoring system and equipment supporting data encryption protection. Background technique [0002] In the monitoring system, it mainly includes front-end equipment, back-end equipment and monitoring center. Among them, the front-end equipment mainly includes equipment for collecting and encoding monitoring information such as audio and video, and the back-end equipment mainly includes equipment for decoding, displaying, playing and storing audio, video and other monitoring information, as well as equipment for controlling front-end equipment, such as cameras. Devices for pan / tilt motion control, camera lens telescopic control, and camera parameter adjustment. The monitoring center is the overall management center of the system, also known as the central platform server, which is mainly responsible for monitoring business fun...
