Bluetooth technology and biometric feature recognition based payment method and system

Abstract

The invention provides a Bluetooth technology and biometric feature recognition based payment method and system. The Bluetooth technology and biometric feature recognition based payment method comprises the steps that a receiver terminal searches potential payers within a preset range through Bluetooth and sends a payment request to payer terminals; the receiver terminal receives encrypted payment preparation instructions returned by the payer terminals and forwards the encrypted payment preparation instructions to a third-party payment server; the third-party payment server obtains payment accounts of the potential payers and corresponding biometric feature information; the receiver terminal acquires the biometric feature information of current payers and sends encrypted biometric feature information to the third-party payment server; the third-party payment server determines the current payers according to the biometric feature information and completes payment according to the corresponding payment preparation instructions; the receiver terminal receives payment results returned by the third-party payment server and forwards the payment results to the payer terminals. By means of the Bluetooth technology and biometric feature recognition based payment method, the efficiency of biometric feature recognition based payment can be improved.

Description

technical field [0001] The invention relates to the technical field of payment, in particular to a payment method and system based on bluetooth technology and biological feature identification. Background technique [0002] In recent years, a variety of offline payment methods have emerged, such as QR code payment, sound wave payment and biometric payment. The advantage of biometric payment over other offline payment methods lies in its security and convenience. Its security lies in that biometric features (such as fingerprints, irises, faces, etc.) are the only identification signs of the user's identity, and other people cannot easily steal them. Its convenience lies in that the biometric feature is an identity code carried by a person, eliminating the trouble of carrying additional equipment. [0003] But biometric payments still have some drawbacks. One of the disadvantages is poor real-time performance. Compared with the exact digital information such as account num...

Problems solved by technology

Manually inputting individual numbers is often cumbersome, time-consuming, and easy to forget; when manually entering group numbers, the computational complexity of the system is still very high; and the problem with using NFC or RFID technology is that the payer needs to take out his own device and place it close to the receiver.
