Background
With the rapid development of scientific technology, more and more intelligent terminals such as mobile phones and tablets begin to use fingerprint identification modules to verify the identity of a user.

Fig. 2-1 is a flow diagram illustrating a fingerprint entry method, as shown in fig. 2-1, according to an exemplary embodiment, the method including:
in step 201, when a fingerprint entry instruction is received, entry indication information is displayed.
The input indication information is used for indicating a user to perform sliding operation on the touch screen according to a preset sliding track. In the process that a user slides on the touch screen according to a preset sliding track, a fingerprint identification module arranged in the terminal can collect fingerprint characteristics of the user so as to store the collected fingerprint characteristics as a fingerprint template of the user. Fig. 2-2 is a schematic structural diagram of a touch screen in a terminal according to an exemplary embodiment, as shown in fig. 2-2, the touch screen may include a display area 01 and a key area 02, and an identifiable area 021 of a fingerprint identification module provided in the terminal is located in the key area 02; referring to fig. 2-2, the predetermined sliding track can be a track 03 from the display area 01 to the key area 02, and an end point a of the predetermined sliding track 03 is located in an identifiable area 021 of the fingerprint identification module; fig. 2-3 are schematic diagrams illustrating a sliding track according to an exemplary embodiment, as shown in fig. 2-3, the preset sliding track can also be a track 04 in the key area 02, and an end point b of the preset sliding track 04 is in the recognizable area 021 of the fingerprint recognition module.
It should be noted that, when the preset sliding track is a track in the key area, the terminal may display a prompt message at a corresponding position in the display area, so as to prompt the user to perform a sliding operation according to the correct preset sliding track. For example, as shown in fig. 2-3, the prompt message may include: please slide in the following direction in the key region, and correspondingly display the sliding direction diagram 041 in the display region.
In step 202, in the process of receiving the sliding operation of the user, the sliding parameters of the sliding operation are collected.
In order to analyze the sliding operation of the user and improve the precision of the sliding operation of the user, the terminal can also acquire the sliding parameters of the sliding operation in the process of receiving the sliding operation of the user. The slip parameters may include: at least one of a sliding track, a sliding speed, a sliding interruption frequency, a number of fingers, and a touch pressure. In the sliding operation process of a user, the terminal can acquire coordinate information of an area, receiving the sliding operation, on the touch screen in real time and determine a sliding track of the sliding operation according to the coordinate information; the sliding speed is the average speed of the terminal in a preset time period determined according to the sliding track and the sliding operation running time, wherein the preset time period can be the sliding operation running time or any time period in the sliding operation running time; the sliding interruption times refer to the times that the fingers leave the touch screen in the sliding operation process of the user; the number of the fingers is the number of the fingers which are in contact with the touch screen at present; the touch pressure is the pressure received by the touch screen in the process of the sliding operation of the user. For example, assuming that the preset sliding track in the terminal is the track 04 shown in fig. 2 to 3, during the sliding operation performed by the user according to the preset sliding track, the sliding parameters of the sliding operation collected by the terminal may be shown in table 1: the sliding track is b 1-b 2, wherein b1 can be the coordinate of the starting point of the sliding operation, and b2 is the coordinate of the current contact point of the user finger; the sliding speed is 0.05 meter per second (m/s), the sliding interruption frequency is 0, the number of fingers is 1, and the touch pressure is 0.2 megapascals (MPa).
TABLE 1
| Sliding track | Sliding speed | Number of sliding interruptions | Number of fingers | Touch pressure |
| b1→b2 | 0.05m/s | 0 | 1 | 0.2MPa |
In step 203, it is determined whether the sliding parameter matches a preset parameter threshold.
In the embodiment of the present disclosure, the preset parameter threshold may be a fixed value, or a range of values, and when the preset parameter threshold is a fixed value, the terminal may determine whether the sliding parameter is equal to the preset parameter threshold when determining whether the sliding parameter matches the preset parameter threshold; when the preset parameter threshold is within the numerical range, the terminal can determine whether the sliding parameter is within the numerical range. When the sliding parameter is not matched with the preset parameter threshold, the terminal may determine that the user needs to adjust the sliding operation, and execute step 204; when the sliding parameter matches the preset parameter threshold, the terminal may determine that the sliding operation of the user meets the preset requirement, and execute step 207. For example, assume that the preset parameter thresholds include: sliding track: b1 to b3, b1 and b3 are respectively the start point coordinates and the end point coordinates of the preset sliding track; sliding speed: 0.04m/s to 0.06 m/s; the sliding interruption times are less than or equal to 2; number of fingers: 1; touch pressure: 0.10.2MPa to 0.3 MPa; since each sliding parameter shown in table 1 is located in the numerical range of the preset parameter threshold, the terminal may determine that the current sliding operation of the user meets the preset requirement, and execute step 207. If the sliding speed is 0.07m/s in the sliding parameters of the sliding operation collected by the terminal, the sliding speed 0.07m/s is within a preset numerical range: 0.04m/s to 0.06m/s, so the terminal can determine that the user needs to adjust the sliding operation and execute step 204.
In step 204, it is determined whether the error between the sliding parameter and the parameter threshold is greater than a preset error threshold.
When the sliding parameter is not matched with the preset parameter threshold, the terminal may further determine whether an error between the sliding parameter and the parameter threshold is greater than a preset error threshold. When the error between the sliding parameter and the parameter threshold is greater than the preset error threshold, the terminal may determine that the fingerprint feature of the user cannot be entered according to the current sliding operation, and execute step 205; when the error between the slip parameter and the parameter threshold is not greater than the preset error threshold, step 206 is executed. For example, assume that for the slip parameter: the sliding speed is 0.005m/s, the sliding speed of the sliding operation collected by the terminal is 0.07m/s, and the preset numerical range is as follows: 0.04m/s to 0.06m/s, the terminal may determine that the error between the sliding speed 0.07m/s and the preset parameter threshold is 0.01m/s, and the error is greater than the preset error threshold of 0.005m/s, so the terminal may determine that the fingerprint feature cannot be entered according to the current sliding operation of the user, and perform step 205.
It should be noted that, when the preset parameter threshold is a numerical range, and the terminal determines an error between the sliding parameter and the parameter threshold, the terminal may respectively calculate an error between the sliding parameter and two end points of the numerical range, and determine an error with a smaller value as an error between the sliding parameter and the parameter threshold. Exemplary, parameter thresholds for slip speed: 0.04m/s to 0.06m/s, the sliding speed of the user collected by the terminal is 0.07m/s, and the errors between the sliding speed and two end points in the numerical range are respectively as follows: 0.03m/s and 0.01m/s, so the terminal can determine a small value of error 0.01m/s as the error between the slip speed and the preset parameter threshold.
In step 205, the user is prompted to resume the swipe operation.
When the error between the sliding parameter and the parameter threshold is greater than the preset error threshold, the terminal can determine that the fingerprint characteristics of the user cannot be input according to the current sliding operation, and prompt the user to perform the sliding operation again. For example, FIGS. 2-4 are schematic diagrams illustrating a terminal displaying a prompt according to an exemplary embodiment, and as shown in FIGS. 2-4, the terminal may display a! Please re-enter ", so as to prompt the user to re-perform the sliding operation. In addition, the terminal may further prompt the user to perform the sliding operation again through voice information or vibration information, and the like, which is not limited in this disclosure.
Thereafter, the terminal may continue to perform step 202, i.e., continue to receive the sliding operation of the user and collect the sliding parameters of the sliding operation.
In step 206, the user is prompted to continue the current sliding operation and adjust the sliding parameters of the current sliding operation.
When the error between the sliding parameter and the parameter threshold is not greater than the preset error threshold, the terminal may determine that, after the user appropriately adjusts the current sliding operation, the fingerprint feature of the user may be entered based on the adjusted sliding operation, and therefore, the terminal may correspondingly generate prompt information for prompting the user to adjust the sliding parameter of the current sliding operation according to the error between the sliding parameter and the parameter threshold. For example, assume that for the slip parameter: the sliding speed is 0.02m/s, when the sliding speed of the sliding operation collected by the terminal is 0.07m/s, the preset numerical range is as follows: when the sliding speed is 0.04m/s to 0.06m/s, the terminal can determine that the error between the sliding speed and the preset parameter threshold is 0.01m/s, and since the error is less than the preset error threshold of 0.02m/s, the terminal can determine that after the sliding speed of the current sliding operation is slowed down by the user, the fingerprint characteristics of the user can be entered based on the adjusted sliding operation. 2-5 are schematic diagrams illustrating another terminal displaying prompt message according to an exemplary embodiment, assuming that the terminal determines that the sliding speed of the sliding operation is faster than the preset speed threshold according to the sliding parameter, but the error from the preset speed threshold is less than the preset error threshold, then a "! Please slow down the sliding speed ", thereby prompting the user to slow down the sliding speed. In addition, the terminal may also prompt the user to adjust the sliding parameter of the current sliding operation through voice information, vibration information, or other manners, which is not limited in this disclosure.
Thereafter, the terminal may repeat the above steps 202 to 206 until the sliding parameter matches the preset parameter threshold.
In step 207, the fingerprinting module is awakened.
When the sliding parameter is matched with the preset parameter threshold value, the terminal can determine that the fingerprint characteristics of the user can be input according to the current sliding operation, so that the fingerprint identification module can be awakened, and the fingerprint characteristics of the user can be collected and input by the fingerprint identification module when the sliding track of the sliding operation of the user passes through the identification area of the fingerprint identification module.
In the embodiment of the present disclosure, the fingerprint identification module may be a pressing type fingerprint identification module, and when a finger of a user slides through an identifiable area of the pressing type fingerprint identification module, the pressing type fingerprint identification module may collect a plurality of frames of fingerprint images, and then splice the plurality of frames of fingerprint images through a preset algorithm to obtain a complete fingerprint feature. Because in the process of the sliding operation of the user, the terminal can collect the sliding parameters of the sliding operation and compare the sliding parameters with the preset parameter threshold value, when the sliding operation of the user is deviated, the user can be timely prompted to adjust the sliding parameters of the sliding operation, so that the sliding operation of the user when the fingerprint is input is standardized, the pressing type fingerprint identification module can smoothly collect complete fingerprint characteristics, and the fingerprint input efficiency is improved. In addition, due to the fact that the pressing type fingerprint identification module is adopted, after the terminal finishes fingerprint input, when a user needs to unlock the terminal or an application program installed in the terminal, fingerprint verification can be conducted in a pressing mode, the pressing type fingerprint verification method is simple in operation, and user experience is improved.
It should be noted that the order of the steps of the fingerprint entry method provided by the embodiment of the present disclosure may be appropriately adjusted, and the steps may also be correspondingly increased or decreased according to the situation. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure is covered by the protection scope of the present disclosure, and thus, the detailed description thereof is omitted.
