1. 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,wherein generating the sequence of fingerprints to be verified according to the fingerprints and the pressing intensities of the N pressing operations further comprises;
classifying operation types of the N pressing operations, wherein the pressing operations of which the pressing intensities exceed a preset threshold value belong to a first operation type and the pressing operations of which the pressing intensities do not exceed the preset threshold value belong to a second operation type;
sequencing the operation types according to pressing moments of the corresponding N pressing operations to obtain a sequence of operations; and
generating the sequence of fingerprints to be verified according to the sequence of operations and the fingerprints.
