Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The unlocking method and apparatus of the embodiment of the present invention are described below with reference to the drawings.
Fig. 1 is a flowchart of an unlocking method according to an embodiment of the present invention.
As shown in fig. 1, the unlocking method includes:
s101, obtaining historical unlocking fingerprint information of a user.
Specifically, historical unlocking fingerprint information of the mobile terminal by the user is obtained. The historical unlocking fingerprint information is input unlocking fingerprint information when the user successfully unlocks the mobile terminal before.
It can be understood that before the historical unlocking fingerprint information is acquired, fingerprint unlocking information input by a user in the process of daily using the mobile terminal can be received. If the input fingerprint information is successfully unlocked, the fingerprint information can be recorded and stored in the mobile terminal as historical unlocking fingerprint information.
For example, the user has accumulated 100 times of successful input of the unlocking fingerprint information at the mobile terminal from the beginning of using the mobile terminal, and the 100 times of unlocking fingerprint information may be used as the historical unlocking fingerprint information.
The mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, and the like.
S102, determining the capacitance value distribution condition of the pixels on the fingerprint chip according to the historical unlocking fingerprint information, and setting a pressure threshold value according to the capacitance value distribution condition.
The fingerprint chip is internally composed of m × n arrayed pixel points, wherein m and n are positive integers. For example, as shown in fig. 2, the interior of the fingerprint chip is composed of 56 × 192 arrays of pixels, that is, 10752 pixels.
It should be understood that when the finger presses the fingerprint identification module, a capacitance is formed between each pixel point on the fingerprint chip and the surface of the finger. Because the distance between the finger peak and the pixel point is close, and the finger valley is relatively far, the capacitance value is different due to the difference of the finger peak and the finger valley.
Specifically, after historical unlocking fingerprint information of a user is acquired, the capacitance value distribution condition of pixels on the fingerprint chip is determined according to the historical unlocking fingerprint information, and a pressure threshold value is set according to the capacitance value distribution condition.
More specifically, the capacitance value of the pixel at 50 deciles is first determined according to the historical unlocking fingerprint information, and then the unlocking pressure value of the user is determined according to the capacitance value of the pixel at 50 deciles. The 50-quantile is that after a group of data is sorted from small to large or from large to small, the position in the middle of the array is the 50-quantile, so that the 50-quantile value is obtained. For example, the capacitance values of the pixels are sorted from small to large, and the capacitance value at the middle position is a 50-quantile value.
Furthermore, after the unlocking pressure value corresponding to the capacitance value of 50 decimals is determined, the pressure threshold value is set according to the unlocking pressure value.
The capacitance value and the unlocking pressure value are in a direct proportion relation. That is, the larger the unlock pressure value, the larger the capacitance value; the smaller the unlock pressure value, the smaller the capacitance value.
In addition, the capacitance value of each pixel in the historical unlocking fingerprint information can be counted in a statistical mode that the capacitance value is used as an abscissa and the number of the pixels is used as an ordinate based on a statistical principle. And determining the capacitance value corresponding to the highest rectangular cylinder in the graph according to the statistical result, namely, the capacitance value with the most distributed pixel numbers. And determining an unlocking pressure value of the user according to the capacitance value, and finally setting a pressure threshold value according to the unlocking pressure value.
For example, 100 times of historical unlocking fingerprint information of a certain user on the mobile terminal is counted, and the statistical result is shown in fig. 3, where an abscissa is a capacitance value of a pixel, and an ordinate is the number of the pixel. As can be seen from fig. 3, the distribution of the pixels is mainly concentrated on that the capacitance is equal to 0.6, that is, the number of the pixels with the capacitance of 0.6 is 3100 at most, and the unlock pressure value is 1 n according to the corresponding relationship between the capacitance and the unlock pressure value. After determining that the user's unlock pressure value is 1 newton, the pressure threshold may be set to 1.5 newtons. When the unlocking is carried out again, the pressure value required to be input by the user is not less than 1.5 newtons.
The magnitude of the pressure threshold may be set according to actual needs, and is not limited herein. For example, because the input pressure is different when the girl and the boy unlock, different pressure thresholds can be set according to the daily unlocking pressure of the girl and the boy to meet the requirements of different individuals.
S103, detecting the pressure value of the user on the fingerprint chip when unlocking is carried out next time.
Specifically, when the user pressed the finger to the fingerprint identification module and carried out the unblock next time, detected the user to the pressure value of fingerprint chip. The previous unlocking does not need to detect a pressure value, and mainly the common unlocking pressure of the user is determined firstly. The unlocking for pressure detection combines the habits of users, so that the personalized requirements are better met.
And S104, if the pressure value is larger than the pressure threshold value, executing unlocking operation.
Specifically, after the pressure value of the user on the fingerprint chip is obtained, whether the pressure value is greater than a pressure threshold value is judged. And if the pressure value is larger than the pressure threshold value, performing unlocking operation on the mobile terminal. For example, the pressure threshold is 1.5 newtons, and if the pressure value input by the user is greater than 1.5 newtons and the input fingerprint information is correct, the unlocking is successful.
And if the pressure value is smaller than the pressure threshold value, displaying prompt information. The prompt message may include voice message and text message. For example, when the pressure value of the fingerprint chip is smaller than the pressure threshold value when the user unlocks, text prompt information is displayed on the screen of the mobile terminal, for example, "the fingerprint unlocking pressure is too small, please increase the pressure", or voice information of "the fingerprint unlocking pressure is too small, please increase the pressure" is played. The user is fed back through the prompt information, and the pressing pressure during unlocking can be increased after the user receives the prompt information, so that the user can unlock the lock correctly.
In summary, according to the unlocking method provided by the embodiment of the invention, the historical unlocking fingerprint information is recorded, and the unlocking pressure threshold is set according to the historical unlocking fingerprint information, so that the pressure needs to be detected when the user unlocks again, the occurrence of a wrong unlocking condition is avoided, and the electric quantity is saved.

Because the distance between the finger peak and the pixel point is close, and the finger valley is relatively far, the capacitance value is different due to the difference of the finger peak and the finger valley.
Specifically, after obtaining the historical unlocking fingerprint information of the user, the setting module 420 determines the capacitance distribution of the pixels on the fingerprint chip according to the historical unlocking fingerprint information, and sets the pressure threshold according to the capacitance distribution.
More specifically, the determination unit 421 first determines the capacitance value of the pixel at 50 decitex according to the history unlocking fingerprint information, and then the setting unit 422 determines the unlocking pressure value of the user according to the capacitance value of the pixel at 50 decitex. The 50-quantile is that after a group of numbers is sorted from small to large or from large to small, the position in the middle of the group of numbers is the 50-quantile, so that the 50-quantile value is obtained. For example, the capacitance values of the pixels are sorted from small to large, and the capacitance value at the middle position is a 50-quantile value.
And then, after the unlocking pressure value of the user is determined, setting a pressure threshold value according to the unlocking pressure value.
The capacitance value and the unlocking pressure value are in a direct proportion relation. That is, the larger the unlock pressure value, the larger the capacitance value; the smaller the unlock pressure value, the smaller the capacitance value.
In addition, the capacitance value of each pixel in the historical unlocking fingerprint information can be counted in a statistical mode that the capacitance value is used as an abscissa and the number of the pixels is used as an ordinate based on a statistical principle. And determining the capacitance value corresponding to the highest rectangle in the graph, namely the capacitance value with the most distributed pixel numbers according to the statistical result.

For example, 100 times of historical unlocking fingerprint information of a certain user on the mobile terminal is counted, and the statistical result is shown in fig. 3, where an abscissa is a capacitance value of a pixel, and an ordinate is the number of the pixel. As can be seen from fig. 3, the distribution of the pixels is mainly concentrated on that the capacitance is equal to 0.6, that is, the number of the pixels with the capacitance of 0.6 is 3100 at most, and the unlock pressure value is 1 n according to the corresponding relationship between the capacitance and the unlock pressure value. After determining that the user's unlock pressure value is 1 newton, the pressure threshold may be set to 1.5 newtons. When the unlocking is carried out again, the pressure value required to be input by the user is not less than 1.5 newtons.
The magnitude of the pressure threshold may be set according to actual needs, and is not limited herein. For example, because the input pressure is different when the girl and the boy unlock, different pressure thresholds can be set according to the daily unlocking pressure of the girl and the boy to meet the requirements of different individuals.
And the detection module 430 is configured to detect a pressure value of the fingerprint chip by the user when unlocking is performed next time.
Specifically, when the user performs the next unlocking, the detection module 430 detects the pressure value of the user on the fingerprint chip. The previous unlocking does not need to detect a pressure value, and mainly the common unlocking pressure of the user is determined firstly. The unlocking for pressure detection combines the habits of users, so that the personalized requirements are better met.
