The invention discloses a face recognition method and device for a multi-payment system based on a block chain, and relates to the field of block chains, and the method comprises the steps: determining a face recognition vector, corresponding to a reference face system, of a user according to the current face recognition data of the user; the reference face system is a system selected from a plurality of face systems of the block chain according to the face risk coefficient; determining the passing probability of the current face data corresponding to each non-reference system based on the relationship between the vector and the passing probability of the non-reference system; determining the face matching value of the current face data corresponding to the non-reference system based on the relationship between the passing probability of the non-reference system selected by the user and the face matching value and the passing probability of the current face data corresponding to the non-reference system; and determining whether the non-reference system performs face recognition on the user based on the matching value of the non-reference system and the face matching value of the user stored in the non-reference system. According to the invention, multi-system payment can be carried out efficiently and safely.
Description
technical field [0001] The present invention relates to the technical field of blockchain, and in particular, to a face recognition method and device for a multi-payment system based on blockchain. 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] At present, in actual payment transactions, it often happens that the customer's balance in each card does not support a single transaction (for example, the balance in each card is less than the payment amount). In this way, multiple payment systems are involved in the customer's payment, especially when it involves inter-bank, the operation is cumbersome, the payment is not safe, and the customer experience is not good. SUMMARY OF THE INVENTION [0004] The embodiment of the present invention provides a face recognition method for a m...
