Embodiment Construction

[0052] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0053] see figure 1 and figure 2 As shown, the implementation of video information encryption control system based on semantic granularity, including:

[0054] (1) Video input interface module, used to receive external original video information;

[0055] (2) The video structured description module receives the original video information sent by the video input module, and extracts the corresponding video structured description content therefrom;

[0056] (3) Data mining and semantic matching reasoning module, which is used to perform data mining on each of the above-mentioned video clips with semantic identification as the smallest granularity unit, and identify whether there are specific content keywords preset by the system to determine whether encryption is required Processing, matching and inferring the keyword to obtain the result s...

Abstract

The invention relates to a system for realizing control over video information encryption on the basis of semantic granularity. The system comprises a video input interface module, a video structuralization description module, a data mining and semantic matching reasoning module, a real-time encryption calculation module and a video output interface module. The invention further relates to a method utilizing the system for realizing the control over the video information encryption on the basis of the semantic granularity. The system and method for realizing the control over the video information encryption on the basis of the semantic granularity enables the encryption effect of videos to be more approximate to the habits of human sense organs, enables the view authority of the videos to be more controllable, effectively solves the problems that the video content is not targeted in the process of encrypting video data, remarkably reduces the computation complexity, shortens the time delay of computation, guarantees a low packet loss rate and high quality of images in the process of transmitting the videos, and is high in practical value, quite strong in adaptive capacity, stable and reliable in working performance, and quite wide in range of application, and the processing process is simple and convenient.

Description

technical field [0001] The invention relates to the field of information security management, in particular to the technical field of content protection of digital video information, and specifically refers to a system and method for implementing video information encryption control based on semantic granularity. Background technique [0002] With the rapid development of computer technology and the Internet, a large number of video devices have been able to conveniently transmit mass digital video information to each other in batches through the Internet, which is beneficial for network users to quickly find, share and use various resources in the network, such as Video movies, surveillance videos, video conferences and video chats, etc. However, some people will maliciously tamper with the content of these important video resources, and then spread them widely on the Internet. This kind of behavior has caused a large-scale leak of video resource information with an import...
