Problems solved by technology

[0003] The mobile fingerprint collection method needs to press the collection module of the terminal, but multiple physical press operations will cause wear and tear on the terminal and reduce the service life of the terminal; the fixed fingerprint collection method collects fingerprints by the user touching the collection module of the terminal, but There are many limiting factors in actual use. For example, when the user's finger is wet, the fingerprint collection function of the terminal cannot be triggered, which causes the problem of fingerprint collection failure, thereby reducing the success rate of fingerprint collection.

Abstract

An embodiment of the invention discloses a fingerprint acquisition method and a terminal. The fingerprint acquisition method includes the steps of obtaining a first command and detecting a plurality of current temperature parameters corresponding to a plurality of preset touch regions according to the first command, the first command being for indication of fingerprint acquisition; determining a first temperature parameter among the plurality of current temperature parameters, the first temperature parameter being the current temperature parameter different from the other current temperature parameters in the plurality of current temperature parameters; determining, from the plurality of preset touch regions, a first touch region corresponding to the first temperature parameter; and starting fingerprint acquisition when the first touch region is a preset fingerprint acquisition region. Thus, the service life of the terminal can be prolonged, and the success rate of the fingerprint acquisition of the terminal is increased.

Description

technical field [0001] The invention relates to fingerprint collection technology, in particular to a fingerprint collection method and a terminal. Background technique [0002] With the continuous advancement and rapid development of mobile communication technology, many smart mobile terminals such as mobile phones and tablet computers are no longer just simple communication devices. It is also getting stronger and stronger, so it is necessary to protect the security of the mobile terminal through various verification methods. At present, commonly used verification methods include password verification, graphic verification, fingerprint verification, etc. Among them, due to the characteristics of fingerprints such as stability and uniqueness, the fingerprint verification method is more secure and convenient, and is widely used. When authentication is performed through the user's fingerprint, the current user's fingerprint needs to be collected. In the prior art, common fin...
