Embodiment 2
[0101] Embodiment 2 is that the mobile phone is in the bright screen unlocking state, and the specific steps are as follows: image 3 shown, including:
[0102] In step 301, the application receives a user's application access request.
[0103] Step 302, the application sends a fingerprint identification request to the fingerprint module of the mobile phone.
[0104] Step 303, the fingerprint module scans the fingerprint.
[0105] Step 304, the fingerprint module sends the scanned fingerprint to the application.
[0106] Step 305, the application compares the scanned fingerprint with the pre-stored fingerprint.
[0107] Step 306, the application sends the fingerprint comparison result to the fingerprint module.
[0108] Step 307, the fingerprint module receives the fingerprint comparison result, and decides whether to stop fingerprint scanning according to the fingerprint comparison result.
Embodiment 3
[0109] Embodiment 3 is that the mobile phone is in the state of bright screen and locked screen, and the specific steps are as follows: Figure 4 shown, including:
[0110] Step 401, the fingerprint module receives the user's mobile phone unlocking request.
[0111] Step 402, the fingerprint module starts to scan the fingerprint.
[0112] Step 403, the fingerprint module compares the scanned fingerprint with the pre-stored fingerprint.
[0113] Step 404, after the fingerprint module confirms that the scanned fingerprint is consistent with the pre-stored fingerprint, stop fingerprint scanning.
[0114] The embodiment of the present invention also provides a terminal fingerprint scanning device, such as Figure 5 shown, including:
[0115]A state module 501, configured to determine that the terminal is in a screen-off state;
[0116] Calculation module 502, configured to acquire the fingerprint scanning frequency corresponding to the current period; the fingerprint scanning...

Abstract
The embodiments of the present invention relate to the field of electronic technology, and in particular to a terminal fingerprint scanning method and device, so as to reduce power consumption of the terminal. The embodiment of the present invention includes: the terminal determines that the screen is off; the terminal obtains the fingerprint scanning frequency corresponding to the current period; the fingerprint scanning frequency corresponding to the current period is based on the use time of the terminal in the historical period and the terminal receiving is determined by the number of fingerprints received; the terminal performs fingerprint scanning according to the fingerprint scanning frequency corresponding to the current time period.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a terminal fingerprint scanning method and device. Background technique [0002] Fingerprints are the uneven lines on the skin at the end of a person's fingers. Fingerprint, because of its lifelong invariance, uniqueness and convenience, has almost become synonymous with biometric identification. . Fingerprintidentification technology corresponds a person with his fingerprint, and his real identity can be verified by comparing his fingerprint with the pre-saved fingerprint. Each person's (including fingerprints) skin texture is unique in patterns, breakpoints and intersections. Only by relying on this uniqueness and stability can we create fingerprint recognition technology. Each person's skin texture, including fingerprints, varies in patterns, breakpoints, and intersections, which are unique and remain unchanged throughout life. Because everyone's fingerprints are diff...
