FINGERPRINT UNLOCKING SYSTEM, ELECTRONIC APPARATUS, AND FINGERPRINT UNLOCKING METHOD

摘要

A fingerprint unlocking system, comprising: a fingerprint sampling screen (12), a database (14), and an unlocking module (16). The fingerprint sampling screen is used to sample fingerprints. The database (14) stores an unlocking password comprising pre-stored fingerprints, pre-stored positions of the pre-stored fingerprints on the fingerprint sampling screen, a pre-stored appearing sequence of the pre-stored fingerprints and/or a pre-stored position variation of the pre-stored fingerprints. The unlocking module (16) determines whether the sampled fingerprints are the pre-stored fingerprints; if so, the unlocking module (16) is also used to determine whether the positions of the sampled fingerprints on the fingerprint sampling screen are consistent with the pre-stored positions of the pre-stored fingerprints on the fingerprint sampling screen; if so, the unlocking module (16) determines the appearing sequence and/or the position variation of the sampled fingerprints are consistent with the pre-stored appearing sequence of the pre-stored fingerprints and/or the pre-stored position variation of the pre-stored fingerprints; if so, the unlocking module (16) unlocks an electronic apparatus. The present fingerprint unlocking system and method add a password unlocking mechanism on the basis of fingerprint recognition to enhance safety. In addition, also disclosed are an electronic apparatus and fingerprint unlocking method.
