A fingerprint recognition method includes: from a time when a finger is detected touching a fingerprint recognition portion, a contact area between the finger and the fingerprint recognition portion is acquired at preset time intervals; when the contact area is smaller than a preset area and a number of repeated acquisition times does not reach a preset number of times, the number of repeated acquisition times is updated. The number of repeated acquisition times is configured to determine that fingerprint recognition fails when being accumulated to reach the preset number of times. Prior to the number of repeated acquisition times reaching the preset number of times, when it is detected that the finger leaves the fingerprint recognition portion, the number of repeated acquisition times is reset.

Fingerprint recognition method and device

A method of recognizing a biological feature is provided. In an example, the method includes: first biological feature data is obtained; a first recognition operation is performed according to the first biological feature data and biological feature template data to obtain a first recognition result; when the first recognition result indicates a match failure, second biological feature data is obtained; and a re-recognition operation is performed according to the second biological feature data and the biological feature template data to obtain a second recognition result. The second biological feature data and the first biological feature data are collected by a same biological feature collector at different moments in a same biological feature recognition process.

Recognizing biological feature

Methods and devices are provided for processing fingerprint. The method may include: acquiring currently input first fingerprint information by a fingerprint detection component when a verification trigger event corresponding to a preset action is detected; adding the first fingerprint information to a fingerprint template library as an unmatched type of fingerprint template when there is no fingerprint template whose matching degree with the first fingerprint information is greater than a first preset threshold in the fingerprint template library and there is a fingerprint template whose matching degree with the first fingerprint information is greater than a second preset threshold in fingerprint template library, wherein the fingerprint template library comprises at least two types of fingerprint templates; and performing the preset action when there is a fingerprint template whose matching degree with the first fingerprint information is greater than the first preset threshold in the fingerprint template library.

Method, terminal, and computer-readable storage medium for processing fingerprint

A method of prompting a failure or error, applicable to a terminal apparatus including a fingerprint recognizer having a sensor array, includes: obtaining electrical signals containing fingerprint information through the sensor array upon a fingerprint recognition being triggered; determining a number of sensors with abnormally-changing electrical signals in the sensor array; and outputting prompt information upon the determined number of sensors exceeds a number threshold.

Error prompting method, device, and electronic apparatus

A fingerprint recognition method includes: acquiring a prestored number of historical defect pixels after a fingerprint recognition sensor captures a first fingerprint image; prohibiting performing matching recognition on the first fingerprint image upon the number of the historical defect pixels being greater than or equal to a first preset number threshold; detecting a number of damaged capturing modules of the fingerprint recognition sensor to obtain a number of current defect pixels; and updating the number of the historical defect pixels by using the number of the current defect pixels, the updated number of the historical defect pixels being used for determining whether to perform matching recognition on a fingerprint image captured next time.

Fingerprint recognition method and apparatus and computer readable storage medium

A method and an apparatus, and a storage medium are provided for controlling a fingerprint sensor in the field of fingerprint identification. The method may include: after an instruction for adjusting a sensitivity of the fingerprint sensor is received, displaying a page for adjusting the sensitivity, in which, at least two different optional sensitivities of a target fingerprint detection module in the fingerprint sensor are displayed on the page; receiving an instruction for selecting the sensitivity, in which, the instruction for selecting the sensitivity includes a target value selected by a user from the at least two different optional sensitivities; and setting a sensitivity of the target fingerprint detection module as the target value.
