Embodiment Construction

[0032] Since most of the existing technologies use a single biometric information for authentication, for example, only through the fingerprint of the user's single finger (usually the index finger) for authentication, and in actual application scenarios, it is inevitable that different users' single-finger fingerprints are similar. , which will lead to misjudgment by the server, and then misoperation. In order to reduce the probability of misoperation of the server as much as possible, the user in this application can register at least two biometric information when registering, and at least two biometric information can be used for authentication when authenticating. Since different users have similar two The probability of the above biometric information is extremely low, so the method provided by this application can effectively reduce the probability of misoperation of the server.

[0033] In order to make the purpose, technical solution and advantages of the present appl...

Abstract

The invention discloses a registration and authentication method and device for biological feature information. The method and device are used for solving the problem that in the prior art, misoperation is likely to occur. The method includes the steps that in registration, a server receives at least two pieces of biological feature information, the biological feature information is saved as registration biological feature information, and the corresponding relations between each piece of registration biological feature information and registered accounts are established; in authentication, at least two pieces of biological feature information to be authenticated are received, an intersection set of the accounts corresponding to the registration biological feature information matched with the biological feature information is determined, and if an account exists in the intersection set, the account is operated. According to the method, registration and operation are performed through at least two pieces of biological feature information, the probability that different users have two or more pieces of similar biological feature information is very low, and therefore the probability of misoperation can be effectively lowered.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a registration and authentication method and device for biometric information. Background technique [0002] With the development of computer technology, methods for authenticating users by using their biometric information have been widely used in various fields. Among them, the biometric information includes fingerprints, palm prints, voice prints, irises, and the like. [0003] The fingerprint is taken as an example for description below. [0004] For example, when a user registers an account, he can submit his own fingerprint to the server as biometric information, and submit an index code to the server (the index code can be composed of numbers with fewer digits, and can be freely set by the user. Such as 6 digits), the server saves the fingerprint and index code, and establishes the corresponding relationship between the fingerprint and the account number regi...
