Abstract

The invention relates to a fingerprint identification method and device. The method comprises the steps that: a fingerprint image is obtained and the characteristic information of the fingerprint image is extracted; current application environmental information is obtained, and a characteristic threshold corresponding to a fingerprint verification safety level is obtained according to the current application environmental information; the extracted characteristic information and the prestored verification characteristic information are compared, if a comparison result reaches a corresponding characteristic threshold, the fingerprint identification is successful, and if the comparison result does not reach the corresponding characteristic threshold, the fingerprint identification is failed. According to the embodiment of the invention, through obtaining the current application environmental information and obtaining the characteristic threshold corresponding to the fingerprint verification safety level according to the current application environmental information, then carrying out fingerprint identification according to the extracted characteristic information and the corresponding characteristic threshold, thus the fingerprint identification process can be completed according to the characteristic threshold corresponding to the fingerprint verification safety level, and thus the fingerprint identification rate is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a fingerprint identification method and device. Background technique [0002] With the rapid development of mobile terminal technology, various mobile terminals such as mobile phones have become very popular, and their functions are constantly increasing. These new functions bring a lot of convenience to users and are deeply loved by users. For example, currently, a mobile phone has a fingerprint identification virtual key, and a user can perform fingerprint identification by touching the virtual key, thereby completing an unlocking operation. [0003] The current fingerprint identification virtual key is realized by setting the fingerprint identification sensor under the glass cover. When the user's finger touches the glass cover, the fingerprint identification sensor recognizes the finger signal and then performs fingerprint identification. [0004] Howev...
