Claim One:
1. A method for controlling unlocking, comprising: scanning a finger of a user by a fingerprint recognition module of a mobile terminal to acquire a reference feature-point set of the finger when a touch operation on the fingerprint recognition module is detected; matching the reference feature-point set with M pre-stored template feature-point subsets, wherein a fingerprint template feature-point set of the mobile terminal comprises the M template feature-point subsets, the number of feature points in each of the M template feature-point subsets is greater than or equal to a first preset threshold, and M is a positive integer greater than one; unlocking when detecting that a current template feature-point set matches with the reference feature-point set, wherein the current template feature-point set comprises m template feature-point subsets of the M template feature-point subsets, and m is a positive integer and is less than M; the m template feature-point subsets having matching priorities higher than that of any template feature-point subset except the m template feature-point subsets of the M template feature-point subsets, and the method further comprising: acquiring N feature-point sets of N fingerprint images that have successively unlocked the mobile terminal for N times; determining the number of times of successful matching for each template feature point of the fingerprint template feature-point set based on the N feature-point sets and the fingerprint template feature-point set; and dividing the fingerprint template feature-point set into the M template feature-point subsets and determining a matching priority of each of the M template feature-point subsets according to the number of times of successful matching of each template feature point and the first preset threshold, the number of template feature points in each of the M template feature-point subsets being greater than or equal to the first preset threshold, and the number of times of successful matching of any template feature point in a template feature-point subset having a higher priority being greater than that of any template feature point in a template feature-point subset having a lower priority.
