Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a flowchart illustrating steps of a fingerprint identification method according to an embodiment of the present invention is shown. The method is applied to a mobile terminal with a touch screen, wherein the touch screen is provided with a fingerprint identification area, and the method comprises the following steps:
In this embodiment, adopt optical fingerprint identification technique under the screen, adopt the touch-sensitive screen to carry out fingerprint identification promptly, be provided with the fingerprint identification region on the touch-sensitive screen. The touch screen can detect whether a user touches the fingerprint identification area, and the detection mode is not limited in detail in the embodiment of the invention and can be set according to actual conditions. When detecting that the user touches the fingerprint identification area, the mobile terminal detects the ambient temperature. Specifically, a temperature sensor, such as a temperature sensitive resistor, may be disposed on the mobile terminal, and the temperature sensor collects the ambient temperature.
And step 102, when the ambient temperature is lower than a preset temperature, adjusting the brightness of the touch screen.
In this embodiment, after the ambient temperature is detected, whether the ambient temperature is lower than the preset temperature is determined. Wherein the preset temperature may be set to a boundary between the normal temperature and the low temperature. For example, if the preset temperature is 0 ℃ and the ambient temperature is 25 ℃, the ambient temperature is determined to be not lower than the preset temperature; and when the ambient temperature is-10 ℃, judging that the ambient temperature is lower than the preset temperature. The preset temperature is not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
At low temperature, human fingers are dry and have shallow lines, and the touch screen of the mobile terminal is also subjected to brightness attenuation. Therefore, when the environment temperature is lower than the preset temperature, the brightness of the touch screen is adjusted, and the touch screen emits strong light. Because the touch screen emits strong light, the energy of the light reflected by the finger is strong, the mobile terminal can receive reflected light conveniently, the difference of the reflected light of the wave crest and the wave trough of the finger is large, clear fingerprint images can be formed according to the reflected light, and the success rate of fingerprint identification is further improved.
The brightness of the touch screen can be adjusted, the whole touch screen can be brightened, and the fingerprint identification area can also be brightened only. For example, the fingerprint identification area displays a brighter white color, and the non-fingerprint identification area displays a black color. The advantage of only brightening the fingerprint identification area is to save power consumption of the mobile terminal. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
And 103, acquiring the fingerprint of the user and performing fingerprint identification.
In this embodiment, the mobile terminal obtains the user fingerprint through the fingerprint identification area, and compares the obtained user fingerprint with a fingerprint preset in the mobile terminal. The fingerprint preset in the mobile terminal is usually collected in a normal temperature environment, that is, the obtained user fingerprint is compared with the preset normal temperature fingerprint. If the preset normal-temperature fingerprint matched with the user fingerprint is found, judging that the fingerprint identification is successful; and if the preset normal-temperature fingerprint matched with the user fingerprint is not found, judging that the fingerprint identification fails.
In summary, in the embodiment of the present invention, when it is detected that the user touches the fingerprint identification area, the ambient temperature is detected; and when the ambient temperature is lower than the preset temperature, brightness adjustment is carried out on the touch screen, and the fingerprint of the user is acquired and subjected to fingerprint identification. At low temperature, the finger of a person can be dry, the lines become shallow, the touch screen can be subjected to brightness attenuation, the brightness of the touch screen is adjusted at the moment, the difference of reflected light can be increased, the success rate of fingerprint identification is improved, and the low-temperature identification performance of the mobile terminal is improved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a fingerprint identification method according to an embodiment of the present invention is shown. The method is applied to a mobile terminal with a touch screen, wherein the touch screen is provided with a fingerprint identification area, and the method comprises the following steps:
In this embodiment, a plurality of preset temperatures may be set, for example, the ambient temperature is lower than the first preset temperature, and the mobile terminal is in a low-temperature environment; the ambient temperature is lower than the second preset temperature, and the mobile terminal is in an ultralow temperature environment. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
The following steps can be specifically adopted for adjusting the brightness of the touch screen:
and a first substep of determining the current brightness of the touch screen.
And a second substep of adjusting the driving voltage of the touch screen according to the current brightness and a preset identification brightness, so that the touch screen reaches the identification brightness under the driving voltage.
Specifically, the minimum brightness required for identifying a fingerprint, i.e., the identification brightness, may be preset in the mobile terminal. And determining a target driving voltage required by the touch screen to reach the recognition brightness according to the difference between the current brightness and the recognition brightness, and then adjusting the driving voltage.
And step 204, when the fingerprint identification is successful, setting the fingerprint of the user which is successfully identified as the preset low-temperature fingerprint.
In this embodiment, if the first fingerprint identification is successful, the user fingerprint that is successfully identified is set as the preset low-temperature fingerprint, and the preset low-temperature fingerprint is stored.
And step 205, generating a prompt message to prompt the user to lengthen the touch time and strengthen the touch strength.
In this embodiment, if the first fingerprint identification fails and the user fingerprint needs to be repeatedly acquired, prompt information may be generated on the touch screen to prompt the user to pay attention to the touch time and the touch force, so that the success rate of the fingerprint identification may be increased when the fingerprint identification is performed again.
And step 206, when the fingerprint identification fails, repeating the steps of acquiring the user fingerprint and carrying out fingerprint identification.
In this embodiment, if the fingerprint identification fails, the step of obtaining the fingerprint of the user and performing the fingerprint identification may be repeated. For example, the user fingerprint acquisition and fingerprint recognition are repeated 3 times. The number of repetitions is not limited in detail in the embodiment of the present invention, and may be set according to actual conditions.
In this embodiment, if the repetition times reaches the set times, the fingerprint identification still fails, and a prompt of fingerprint failure may be generated. And if the fingerprint identification is successful within the set times, judging whether the fingerprint of the user with the identification failure meets the preset condition. For example, if the set number of times is 3, and fingerprint identification is successful when the 3 rd time is repeated, the fingerprints of the users with the 1 st and 2 nd identification failures are judged, and whether the fingerprints of the users with the two previous identification failures meet the preset condition is judged.
Optionally, the preset condition is that the similarity between the fingerprint of the user with the failed identification and the fingerprint of the user with the successful identification is greater than a first preset value, and the false recognition rate when the fingerprint of the user with the failed identification is used as the fingerprint of the user with the successful identification is lower than a second preset value.
For example, the similarity of the fingerprint of the user with the failed identification at the 1 st time is 84% compared with the fingerprint of the user with the successful identification at the 3 rd time, and if the fingerprint of the user with the failed identification at the 1 st time is taken as the fingerprint of the user with the successful identification, the false recognition rate is 25%; the similarity of the fingerprint of the user with failed identification at the 2 nd time is 90% compared with the fingerprint of the user with successful identification at the 3 rd time, and if the fingerprint of the user with failed identification at the 2 nd time is taken as the fingerprint of the user with successful identification, the false recognition rate is 25%. The first preset value can be set to 85%, the second preset value is set to 30%, the fingerprint of the user with the 1 st identification failure does not meet the preset condition, and the fingerprint of the user with the 2 nd identification failure meets the preset condition. Or the first preset value is set to be 80%, and the second preset value is set to be 30%, so that the fingerprints of the users who failed in the previous two identification processes meet the preset condition. The first preset value and the second preset value are not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
Wherein the false rate is the ratio of the number of misjudged fingerprints to the total number of fingerprints. For example, after the first fingerprint identification fails, 3 fingerprint identifications are repeated, and when the fingerprint identification is repeated for the 3 rd time, the total number of fingerprints is 4, if the fingerprint of the user with the 1 st identification failure is taken as the fingerprint of the user with the identification success, the fingerprint of the user is a misjudged fingerprint, the number of the misjudged fingerprints is 1, and the false rate is 25%.
And 208, if the preset condition is met, setting the fingerprint of the user with the identification failure as the preset low-temperature fingerprint.
In this embodiment, if the preset condition is satisfied, the fingerprint of the user with the failed identification is set as the preset low-temperature fingerprint, and the preset low-temperature fingerprint is stored. For example, the fingerprint of the user with the failed 2 nd identification satisfies the preset condition, and the fingerprint of the user with the failed 2 nd identification is set as the preset low-temperature fingerprint. Further, a preset ultra-low temperature fingerprint may be set and stored, for example, if the fingerprint of the user whose identification failed does not satisfy the preset condition that the similarity is greater than 85% and the recognition rate is less than 30%, but satisfies the preset condition that the similarity is greater than 80% and the recognition rate is less than 30%, the fingerprint of the user whose identification failed may be set as the preset ultra-low temperature fingerprint. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
And 209, when the environment temperature is not lower than the preset temperature, performing fingerprint identification according to a preset normal-temperature fingerprint.
In this embodiment, when the ambient temperature is not lower than the preset temperature, the mobile terminal is in a normal temperature environment, and fingerprint identification can be performed according to the preset normal temperature fingerprint first, which is not described herein again.
And 210, if the identification fails when the fingerprint identification is carried out according to the preset normal-temperature fingerprint, carrying out the fingerprint identification according to the preset low-temperature fingerprint.
In this embodiment, when carrying out fingerprint identification failure according to predetermineeing normal atmospheric temperature fingerprint, carry out fingerprint identification according to the predetermined low temperature fingerprint in the mobile terminal, further can discern according to predetermineeing ultra-low temperature fingerprint. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
In summary, in the embodiment of the present invention, when it is detected that the user touches the fingerprint identification area, the ambient temperature is detected; and when the ambient temperature is lower than the preset temperature, brightness adjustment is carried out on the touch screen, and the fingerprint of the user is acquired and subjected to fingerprint identification. At low temperature, the finger of a person can be dry, the lines become shallow, the touch screen can be subjected to brightness attenuation, the brightness of the touch screen is adjusted at the moment, the difference of reflected light can be increased, the success rate of fingerprint identification is improved, and the low-temperature identification performance of the mobile terminal is improved.
Further, at normal temperature, if fingerprint identification fails according to a preset normal temperature fingerprint, fingerprint identification can be performed according to a preset low temperature fingerprint, so that the normal temperature identification performance of the mobile terminal is improved, and the use experience of a user is improved.
