Claim One:
1. A method for controlling unlocking, comprising: acquiring n2 underlying data values through n2 normal sensing electrodes of a fingerprint recognition module of a mobile terminal when a touch operation on the fingerprint recognition module is detected, wherein the fingerprint recognition module comprises n1 abnormal sensing electrodes and the n2 normal sensing electrodes, n1 and n2 being positive integers; determining n1 reference underlying data values corresponding to the n1 abnormal sensing electrodes according to the n2 underlying data values acquired by the n2 normal sensing electrodes, wherein the n1 reference underlying data values and the n2 underlying data values form fingerprint data; obtaining a fingerprint image according to the fingerprint data; extracting feature points from the fingerprint image to form a reference feature point set; matching the reference feature point set with template feature points of a pre-stored fingerprint template feature point set in descending order of matching priority of the template feature points, wherein a probability of successful matching of a template feature point having a higher matching priority is greater than that of a template feature point having a lower matching priority; and unlocking the terminal when detecting that the number of template feature points that are matched with the reference feature point set is greater than a first preset threshold.
