[0018] The first embodiment of the present invention discloses a fingerprint-based task execution method. This method is used for a mobile terminal with a camera and a light source. Such as figure 1 As shown, the method includes the following steps:

[0019] Step S101: Detect a first temperature of an area within a first distance from a lens surface of a camera.

[0020] Specifically, the mobile terminal may be provided with an infrared detector to detect the first temperature. The first distance can be set by the mobile terminal system or the user. The smaller the first distance is, the closer the finger of the mobile terminal user is to the lens surface of the camera if the camera and the light source are to be turned on.

[0021] Step S102: comparing the first temperature with the pre-stored second temperature.

[0022] The second temperature can be set by the mobile terminal system or the user, and is generally close to the temperature of the human body.

[0035] The second embodiment of the present invention discloses a fingerprint-based task execution method. This method is used for a mobile terminal with a camera and a light source. Such as figure 2 As shown, the method includes the following steps:

[0036] Step S201: Obtain a second fingerprint image collected by a camera.

[0037] Generally speaking, the camera can collect multiple second fingerprint images, and use the multiple second fingerprint images as comparison images for comparison of fingerprints, so that the second fingerprint images can contain more comprehensive fingerprint information.

[0038] Step S202: Encrypt the second fingerprint image according to the first encryption algorithm.

[0039] Through this step, the second fingerprint image can be encrypted to improve the security of the second fingerprint image and prevent the second fingerprint image from being stolen by others.

[0040] Step S203: storing the encrypted second fingerprint image.

[0059] Step S301: Obtain a second fingerprint image collected by a camera.

[0060] Generally speaking, the camera can collect multiple second fingerprint images, and use the multiple second fingerprint images as comparison images for comparison of fingerprints, so that the second fingerprint images can contain more comprehensive fingerprints.

[0061] Step S302: Encrypt the second fingerprint image according to the first encryption algorithm.

[0062] Through this step, the second fingerprint image can be encrypted to improve the security of the second fingerprint image and prevent the second fingerprint image from being stolen by others.

[0063] Step S303: storing the encrypted second fingerprint image.

Abstract

The embodiment of the invention provides a task execution method based on fingerprint, and the method is used for a mobile terminal with a camera and a light source. The method comprises the steps: detecting the first temperature of a region within a first distance to the surface of a lens of the camera; comparing the first temperature with pre-stored second temperature; starting the camera and the light source if the first temperature is higher than the second temperature; obtaining a first fingerprint image collected by the camera; comparing the first fingerprint image with a pre-stored second fingerprint image; and executing a task corresponding to the second fingerprint if the first fingerprint image is matched with the second fingerprint image. The embodiment of the invention also provides the mobile terminal. According to the embodiment of the invention, the camera and the light source are triggered to be started for the photographing of the fingerprint, and a mode of fingerprint photographing is used for fingerprint comparison, thereby achieving the recognition of fingerprint under the condition of wet hands. Moreover, the mode of fingerprint photographing can be used for collecting more complete fingerprint, and improves the fingerprint recognition rate.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fingerprint-based task execution method and a mobile terminal. Background technique [0002] Mobile terminals in the prior art generally have a fingerprint recognition function. The fingerprint identification function in the prior art is generally realized by setting an independent fingerprint identification module. The fingerprint identification method of the mobile terminal in the prior art is mainly as follows: when the finger touches the fingerprint button of the fingerprint identification module, an electric field is formed by using the silicon wafer and the conductive subcutaneous electrolyte, and the fluctuation of the fingerprint will cause the pressure between the two. There are different changes in the difference, so that accurate fingerprint determination can be realized. Based on this principle, the fingerprint recognition method in the prior art has a cert...
