Description

Technical Field

[0002] With the rapid advancement of video image technology, the security of video data has become a focus of attention. Especially in the fields of security and industrial production, video data is still transmitted in the form of naked streams, or even spread through the Internet. This practice hides huge security risks. For data security management in these fields, this is undoubtedly a severe challenge.

[0003] First, the naked streaming transmission method makes video data easy to be intercepted and tampered with, which poses a great threat to security and industrial production. Once the video data is maliciously used, it may lead to serious consequences, such as production accidents and security vulnerabilities. In addition, the redundant storage and transmission of video data also increases costs and reduces efficiency. When an emergency occurs, it is necessary to manually replay the long video to find key information, which is not only time-consuming and laborious, but may also miss important clues.

[0004] In order to meet these challenges, relevant national departments have issued a series of policies and regulations to guide the construction of network monitoring security systems. However, the standard mainly focuses on the technical requirements of information security, and does not propose specific solutions on how to achieve these requirements and what equipment and methods to use.

[0072] A device for realizing video security and intelligent application of the present invention comprises:

[0073] Uplink video data module:

[0074] This module monitors and manages the data transmission activities of the upstream network port. When the streaming module starts the streaming media playback service, the upstream video data module will strictly check all video data packets to be transmitted to ensure that they meet the preset encryption standards. These data packets may be in RTP, PS, ES, FLV and other formats. In addition, the module will resolutely prevent any video data packets from flowing back to the device through the upstream channel, thereby effectively preventing potential data leakage risks.

[0075] This module controls the uplink transmission of video data packets to ensure the security of data during transmission; monitors whether the transmitted video data packets meet the encryption requirements and encrypts the data packets that do not meet the requirements; prohibits the transmission of downlink video data packets to prevent data leakage.

[0076] Downlink data module:

[0077] The downlink data module focuses on the data transmission management of the downlink network port.

The processed video data can be transmitted to the upstream streaming unit through a pipeline for further processing, or it can be directly stored in the video storage module, or connected to the video intelligent application module for intelligent analysis and application.

[0080] Video encryption and decryption module:

[0081] This module provides encryption and decryption services for video data, and supports multiple encryption algorithms including SM1, SM4, DES, etc. The video encryption and decryption module is one of the key components to ensure the secure transmission of video data.

[0082] Video intelligence application module:

[0083] The video intelligent application module includes a video intelligent parsing unit and a parsing data application unit.

[0084] Video Intelligent Analysis Unit: This unit uses deep learning algorithms to identify and analyze abnormal behaviors in videos. When abnormal behaviors are detected, the Video Intelligent Analysis Unit pushes the abnormal results to the Analysis Data Application Unit for further processing.

[0085] Analysis data application unit: This unit is responsible for pushing the abnormal results provided by the video intelligent analysis unit to the data business system for processing, such as storage and retrieval. At the same time, the analysis data application unit can also control peripheral devices through serial ports, network protocols, etc. to achieve linkage control between multiple devices. For example, when a person is detected crossing a restricted area, the analysis data application unit can control the alarm system to sound an alarm; when an open fire is detected, the fire protection system can be triggered to perform fire extinguishing operations.

[0086] This device realizes the secure transmission and intelligent processing of video data through the collaborative work of multiple modules.
