Problems solved by technology

[0004] The purpose of the present invention is to propose a monitoring video content protection method and system, which can effectively realize the protection of the monitoring video content, overcome the problem that the monitoring video content in the prior art is basically plain text, and easily cause the leakage of the video content. And there is no need to set a password for the player, and it does not restrict the player from playing other content

Embodiment 1

[0057] figure 1 It is a schematic flowchart of a method for protecting surveillance video content provided by Embodiment 1 of the present invention. see figure 1 , a surveillance video content protection method comprising:

[0058] S101: Using a key to encrypt the content of the surveillance video to obtain multi-level encrypted data.

[0059] S102: Burn the multi-level encrypted data to an external storage device (such as a DVD disc).

[0060] S103: Decrypt the multi-level encrypted data in the external storage device to obtain the decrypted surveillance video content.

[0061] S104: After the decryption is successful, play the decrypted surveillance video content.

[0062] figure 2 It is a block diagram of encryption and decryption of surveillance video content provided by Embodiment 1 of the present invention.

[0063] image 3 It is a schematic diagram of the encryption process of surveillance video content provided by Embodiment 1 of the present invention. combin...

Embodiment 2

[0079] Figure 5 It is a schematic diagram of a surveillance video content protection system provided in Embodiment 2 of the present invention. see Figure 5 , a monitoring video content protection system includes: a monitoring subsystem 501 , a playback subsystem 502 , and an authorization subsystem 503 .

[0080] The monitoring subsystem 501 establishes a connection with the IP camera, receives the monitoring video content collected by the camera in real time, realizes encryption, recording, and playback of the monitoring content, and burns the encrypted monitoring content to an external storage device, such as a DVD disc; wherein, The encryption process can be completed by calling the first encryption card through the encryption library, and then scrambling and multiplexing; when the monitoring subsystem 501 plays back the encrypted monitoring content, the USBKEY library calls the USBKEY to decrypt the encrypted monitoring content.

[0081] The playback subsystem 502 comp...

Abstract

The invention discloses a protection method of surveillance video content and a protection system of surveillance video content. The protection method of surveillance video content includes the steps: utilizing a first secret key to encrypt the surveillance video content to obtain ciphertext video streaming; utilizing a second secret key to encrypt the first secret key; multiplexing the ciphertext video streaming and encrypted first secret key according to multiplexing rules to obtain multistage enciphered data, and recording to external storage equipment; when the multistage enciphered data are played, demultiplexing the multistage enciphered data according to the multiplexing rules to obtain the ciphertext video streaming and the encrypted first secret key; and deciphering the encrypted first secret key according to the second secret key of USBKEY to obtain the encrypted surveillance video content. The protection method of surveillance video content and the protection system of surveillance video content effectively achieve protection of the surveillance video content and solve the problems that the surveillance video content in the prior art is mainly proclaimed in writing, and leakage of a secret of the video content is easily caused.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and system for protecting contents of surveillance videos. Background technique [0002] As a combination of traditional video technology and modern communication technology, video surveillance has attracted more and more attention at home and abroad. In recent years, with the popularization of broadband, the development of computer technology, and the improvement of image processing technology, video surveillance is being more and more widely used in the field of security, and it is an important means to assist public security departments in fighting crime and maintaining social stability. The basic business function of video surveillance is to provide means of real-time monitoring, and to record and store the monitored pictures for later playback. [0003] The existing video surveillance systems basically do not encrypt the content of the surveillance video...
