Abstract

The invention provides a secure fingerprint transaction paying method and system. The system comprises a paying terminal, a server and a mobile terminal which are in wireless communication connection. The method comprises the following steps: the paying terminal collects and obtains fingerprint image information; characteristic data of the fingerprint image information are extracted and sent to the server; the server judges whether the characteristic data are stored in a database, and if yes, identification is passed; the paying terminal submits a dynamic password identification request to the server, and the server sends a first random verification code to the mobile terminal legally registered by a paying party; the mobile terminal receives a second random verification code and inputs the code, if the server determines that the second random verification code has timeliness, and whether the second random code and the first random verification code are consistent is compared; and if the second random code and the first random verification code are consistent, verification is passed. At least double identification and verification are adopted to ensure that the paying party is a legal user, the characteristic of concise and convenient transaction flow is considered, and the security level of a financial transaction process is increased.

Description

technical field

[0001] The invention relates to the field of transaction payment, in particular to a method and system for secure fingerprint transaction payment. Background technique

[0002] Fingerprint payment is undoubtedly one of the most promising technologies in the current wave of mobile payment. Since there is no need to use actual credit media (such as cards, account numbers, checks, etc.) during payment verification, it brings great convenience to users. Compared with credit media (cards, account numbers, checks, etc.) fingerprints do not need to worry about loss. Theoretically, the probability of two fingerprints being repeated is 1 in 64 billion. As a password, fingerprints already have sufficient security and verification uniqueness. However, this system still has loopholes under the current technical conditions, and the loopholes are enough to offset the security of payment.

[0003] At present, the entire fingerprint recognition sensor can be roughly divid...
