  • Publication number: 20190087637
    Abstract: A method and an apparatus for updating fingerprint templates, and a mobile terminal are provided. The method includes acquiring a fingerprint image input by a user. The fingerprint image is compared with fingerprint templates pre-stored in a fingerprint template set, where the fingerprint template set comprises N fingerprint templates and N is a positive integer. A mobile terminal performs a target operation when a match value between the fingerprint image and an ith fingerprint template of the fingerprint template set is greater than a first preset threshold. The method determines whether the match value set is greater than a second preset threshold. The method generates a new fingerprint template based on the fingerprint image and adds the new fingerprint template to the fingerprint template set when the match value between the fingerprint image and the ith fingerprint template is greater than the second preset threshold.
