A user account login method and device

Abstract

The invention is applicable to the technical field of data processing, and provides a user account login method and device, and the method comprises the steps: obtaining a finger vein image of a current operation user if an account login instruction is received; Extracting a standard vein image of the account identifier from the vein template library, and calculating a matching degree between thefinger vein image and the standard vein image; If the matching degree is greater than a preset matching threshold, acquiring a plurality of finger images of the user at a preset acquisition frequency;Determining biological characteristic parameters of the user based on the plurality of finger images; And if the biological characteristic parameters are matched with the standard biological parameters of the user, responding to the account login instruction. A vein image in a finger of a user is collected; According to the invention, the fingerprint sleeve cannot be counterfeited by wearing thefingerprint sleeve, so that the reliability of account verification can be improved, the biological characteristic parameters of the user can be collected, the current authenticated user is subjectedto living body detection, and the user is further prevented from illegally charging a legal user for account login through a counterfeiting tool.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method and device for logging in a user account. Background technique [0002] As the number of applications and service systems continues to increase, users need to perform login operations more and more frequently. User accounts contain user privacy information. Therefore, how to securely and efficiently identify users in the process of user login Verification is even more important. Existing user account login technology generally uses fingerprint recognition or manual password input to log in. However, fingerprint information can be forged through fingerprint sleeves, and user passwords may also be leaked. Therefore, the existing user account greater security risk. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a user account login method and device to solve the existing user account login technol...
