Fingerprint information storage method and device and mobile terminal

An embodiment of the invention discloses a fingerprint information storage method and device and a mobile terminal. The method includes: receiving to-be-verified fingerprint information input by a user operating the mobile terminal; judging whether the to-be-verified fingerprint information is matched with any one fingerprint verification information pre-stored in a fingerprint database or not; if not, detecting whether the mobile terminal successfully execute the target operation corresponding to the to-be-verified fingerprint information in a preset time period or not; if so, storing the to-be-verified fingerprint information into the fingerprint database to serve as fingerprint verification information. By the method, the fingerprint identification success rate of the mobile terminal can be increased. 本发明实施例公开了种指纹信息的存储方法、装置及移动终端，其中，该方法包括：接收用户对移动终端进行操作输入的待验证指纹信息；判断所述待验证指纹信息是否与预先存储的指纹数据库中的任指纹校验信息相匹配；若不匹配，则检测预设时长内所述移动终端是否成功执行所述待验证指纹信息对应的目标操作；若是，将所述待验证指纹信息作为指纹校验信息存储至所述指纹数据库中。采用本发明实施例，能够提升终端指纹识别的成功率。
