Abstract
Methods and devices are provided for verifying a fingerprint in the field of computer technology. The method includes: N pressing operations successively performed by a finger of a user within an area for acquiring the fingerprint are acquired; a sequence of fingerprints to be verified is generated according to fingerprints and pressing intensities of the N pressing operations; the sequence of fingerprints to be verified is compared with a reference sequence of fingerprints; and when the sequence of fingerprints to be verified is the same as the reference sequence of fingerprints, it is determined that the fingerprint of the user is successfully verified.
Claims19
A method for verifying a fingerprint, comprising:
- acquiring N pressing operations successively performed by a finger of a user within an area for acquiring the fingerprint, wherein N>1;
- generating a sequence of fingerprints to be verified according to fingerprints and pressing intensities of the N pressing operations;
- comparing the sequence of fingerprints to be verified with a reference sequence of fingerprints;
- and
- determining that the fingerprint of the user is successfully verified when the sequence of fingerprints to be verified is the same as the reference sequence of fingerprints.
A device for verifying a fingerprint, comprising:
- a processor;
- and
- a memory configured to store instructions executable by the processor, wherein the processor is configured to:
- acquire N pressing operations successively performed by a finger of a user within an area for acquiring the fingerprint, wherein N>1;
- generate a sequence of fingerprints to be verified according to fingerprints and pressing intensities of the N pressing operations;
- compare the sequence of fingerprints to be verified with a reference sequence of fingerprints;
- and
- determine that the fingerprint of the user is successfully verified when the sequence of fingerprints to be verified is the same as the reference sequence of fingerprints.
A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a mobile terminal, cause the mobile terminal to perform:
- acquiring N pressing operations successively performed by a finger of a user within an area for acquiring a fingerprint, wherein N>1;
- generating a sequence of fingerprints to be verified according to fingerprints and pressing intensities of the N pressing operations;
- comparing the sequence of fingerprints to be verified with a reference sequence of fingerprints;
- and
- determining that the fingerprint of the user is successfully verified when the sequence of fingerprints to be verified is the same as the reference sequence of fingerprints.
