Abstract

The invention provides a method and system for determining a face recognition threshold value by analyzing transaction risks, and relates to the technical field of financial data processing, and the method comprises the steps: dividing a predetermined region into a plurality of sub-regions, and determining a plurality of transaction places of each sub-region; determining an environment risk vector according to the transaction data; classifying customers in the predetermined area; for each customer category, determining a risk probability corresponding to the customer category; performing clustering analysis on the plurality of sub-regions to obtain a plurality of region subsets; determining a relationship between a face matching threshold and a risk probability according to the transaction data of the region subset; for each customer, determining the customer category to which the customer belongs, and taking the risk probability corresponding to the customer category as the risk probability corresponding to the customer; and when the customer initiates a transaction, determining a face matching threshold value of the customer in the transaction according to the relationship between the face matching threshold value of the transaction site where the transaction is initiated and the risk probability and the risk probability corresponding to the customer.

Description

technical field [0001] The invention relates to the technical field of financial data processing, in particular to a method and system for determining a face recognition threshold by analyzing transaction risks. Background technique [0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] When a customer conducts a transaction, the risk of each transaction location is different. Usually, the bank transaction system uses a fixed face recognition threshold to perform face recognition on customers, which may cause risks due to the low threshold. [0004] To sum up, there is an urgent need for a technical solution that can overcome the above shortcomings and can dynamically adjust the face recognition threshold by analyzing transaction risks. SUMMARY OF THE INVENTION [0005] In order to solve the problems exi...
