Video conference data security sharing method

Abstract

The invention relates to a video conference data security sharing method. The method comprises the following steps: determining a k value through a privacy disclosure threshold value and a data quality threshold value; performing k-anonymization operation on the terminal data set by using the determined k value to obtain a k-anonymized data set; randomly selecting a tuple from each anonymous group of the k-anonymized data set to form a recombined data set; encrypting each data subset in the recombined data set by using a randomly selected key, storing the encrypted recombined data set in a content server, and splitting the randomly selected key into n sub-keys; generating a mapping position of each sub-key in the DHT network; and when the application applies for data to be shared to the sharing party, accessing the mapping position of each sub-key in the DHT network according to the applied access key, determining the key of each data subset corresponding to the data to be shared, and obtaining corresponding shared data. According to the invention, the security of shared data is improved.

Description

technical field [0001] The invention relates to the technical field of information security transmission, in particular to a video conference data security sharing method. Background technique [0002] With the development of the times, the public's communication method is forced to change rapidly from face-to-face to digital, which makes the application of video conferencing more and more extensive. The widespread deployment of 5G communication applications has accelerated the iterative upgrade of the application ecological chain of the video conferencing industry in a more intelligent, efficient, and faster direction, which has become the core and key to firmly grasping users. As a communication method that allows all parties to transmit video and audio data in real time through the network and terminal communication equipment, video conferencing has unique advantages in continuously improving user communication efficiency, reducing corporate travel costs, and improving ma...

Problems solved by technology

This kind of mass data circulation and sharing that gathers the wisdom of the public is undoubtedly necessary for the development of the video conferencing industry ecological chain. However, due to (1) all parties in the video conferencing industry application ecological chain (network operators, cloud service providers, Vertical industry application providers and industry customers, etc.) often share video conference terminal (referred to as terminal) data according to their own needs, and the cross-domain flow of data will increase the risk of terminal privacy data exposure

(2) The video conferencing data using 5G communication has the characteristics of rapid dissemination and rapid spread of behavior, which increases the risk of terminal shared data carrying private information being coveted, stolen, and analyzed by others for profit

The potential safety hazards of the above parties in sharing terminal privacy data will make users feel insecure and unwilling to participate, resulting in: (1) In video conferencing scenarios, data is like an isolated island because the data of various departments of the enterprise cannot be shared The same lack of relevance, unable to give full play to the value of massive data

(2) On the application ecological chain of the video conferencing industry, many companies refuse to share their private information and sensitive data due to terminal data security issues, thus failing to improve the data quality and terminal experience of video conferencing applications, which deviates from the purpose of big data services and the development of the 5G era need
