Abstract

The invention discloses a credit big data-oriented risk control method and a credit big data-oriented risk control system. The credit big data-oriented risk control method comprises the following steps of: finishing data acquisition by terminal equipment, finishing data fusion and cleaning by a server, labeling an attribute label and a main body label and the like to realize data preprocessing; designing a risk control module for native data acquired by the trusted terminal, and dividing the data into different sensitivity levels by performing tagging processing and sensitivity division on thedata to realize first-level risk control; for the initial credit problem of a user of the data storage platform, evaluating the initial credibility and authority of a data visitor by analyzing a mainbody label in the native data, so as to achieve the purpose of secondary risk control; and finally, for the problem that the system and the storage platform need to monitor data visitor behaviors inreal time, dynamically defining the trust degree of the subject according to the visitor behaviors so as to complete three-level risk control for credit big data.

Description

technical field

[0001] The invention belongs to the field of security technology, and in particular relates to a credit big data-oriented risk control method and a system thereof. Background technique

[0002] With the continuous development of Internet technology, the importance of data credibility issues has gradually become more prominent, and the private information contained in credit big data is also increasing day by day. Due to the wide variety of credit big data and multi-source heterogeneity, the effect of credit big data risk control methods is often unsatisfactory. Therefore, how to design a risk assessment method with high security, reliability and systematic important.

[0003] Generally speaking, the reasons for the low risk control effect of credit big data can be roughly divided into the following three aspects: First, because the credit data collected by different terminals is multi-source heterogeneous data, the amount of information is large but the qual...

Embodiment Construction

[0061] The present invention provides a credit big data-oriented risk control method. Aiming at the different impacts of data at different stages on risk control, a risk control method based on credit big data is designed, and a risk control module is designed for the original data collected by trusted terminals. By labeling the data and dividing the sensitivity, the data is divided into different sensitive levels, and then the first-level risk control is realized; for the initial credit of the users of the data storage platform, the data access is evaluated by analyzing the subject labels in the original data The initial trust degree of the visitor, to achieve the purpose of secondary risk control; for the problem that the system and the storage platform need to monitor the behavior of the data visitor in real time, relying on the blockchain technology, the trust degree is dynamically defined according to the behavior of the visitor, so as to complete Three-level risk control ...
