Embodiment 1

[0044] refer to figure 1 , an encryption method for private data transmission, comprising the following steps:

[0045] The step of constructing a mapping-association structure is to construct a mapping-association structure, which includes mapping fields logically associated with each other and domain attributes of each mapping field.

[0046] In the specific application scenario of big data analysis, according to the specific data content and specific data format in the user data information collected, aggregated and stored for users, a corresponding mapping association structure is constructed. The mapping association structure includes a certain number of mapping fields, and each mapping field corresponds to a type or a dimension of user data information, such as user basic information, user-related objects, user behavior, location and time, track path, transaction process, etc. correspond to a mapping domain respectively. Obviously, among these user data information, th...

Abstract

The invention provides an encryption method and device for private data transmission. For the private data that needs to be transmitted through network media and stored and analyzed on the network side in the application process of big data analysis, the present invention converts it into encrypted representation data processed by isomorphic mapping, and then utilizes the encrypted representation data and The isomorphic attributes between the original privacy data realize the mining and analysis of data-related rules, so that the encrypted representation data shields the effective content of user privacy data, avoiding direct network transmission of user privacy data and centralized storage on the network side , which fundamentally reduces data security risks and protects user privacy rights.

Description

technical field [0001] The invention relates to the technical field of big data analysis and processing, in particular to an encryption method and device for private data transmission. Background technique [0002] With the development of computer information technology, human society has fully entered the era of big data, and big data analysis and processing has become a basic structure in many aspects of production and life. [0003] Big data analysis and processing first requires the collection, aggregation, and storage of massive data information, and then cleans, integrates, and structurizes the data information to form a data form that is easy to analyze. Potential related rules between data information obtained in terms of behavior, location, time, process, etc.; finally, based on the relevant rules, the probability of event occurrence is evaluated, and a corresponding response is given according to the probability. [0004] However, in the application scenarios of b...
