However, the fingerprint information collected by this one-time collection of fingerprint information may not be perfect and cannot include the fingerprint information of the user's finger. All fingerprint data, so subsequent fingerprint recognition will not be sensitive enough. For example, the fingerprint information collected at one time may not include the fingerprint information of all angles of the user's finger.

Fig. 2 is a flow chart of another method for collecting fingerprint information provided by an embodiment of the present invention, and the subject of execution of the method is a terminal. Referring to Fig. 2, this method comprises the steps:

Step 201: When a touch operation is detected based on the screen, determine the touch duration of the touch operation.

Wherein, the touch operation refers to a touch operation on the screen, and may specifically include a touch operation such as a press operation or a slide operation that can generate a fingerprint on the screen.

In practical applications, the touch operation on the screen is usually performed by the user through the user's finger when using the terminal. Therefore, in the embodiment of the present invention, in order to improve the sensitivity of fingerprint identification, the touch operation generated The fingerprint information is collected, and the stored fingerprint information is updated based on the collected fingerprint information.

In the embodiment of the present invention, it is considered that when the touch duration is short, if the fingerprint information generated by the touch operation is not clear enough, or the components for collecting fingerprint information are not sensitive enough, etc., the fingerprint generated by the touch operation may not be able to be detected. Accurate collection of information. Therefore, in order to improve the accuracy of fingerprint information collection, when a touch operation is detected based on the screen, the touch duration of the touch operation can also be determined first, so that fingerprint collection can be performed when the touch duration reaches a sufficient length.

Specifically, timing may be started when a touch operation is detected based on the screen, so as to determine the duration of the touch operation, that is, the touch duration, through timing.

Step 202: When the touch duration is longer than the first preset duration, collect fingerprint information generated by the touch operation through the fingerprint sensor disposed under the screen.

Wherein, the first preset duration may be set by default by the terminal, or may be set by a user, which is not limited in this embodiment of the present invention. For example, the first preset duration may be 0.5 second or 1 second.

When the touch operation is a pressing operation and the pressing duration of the pressing operation is longer than the first preset duration, it indicates that the pressing operation is a long pressing operation. Since the long pressing operation can usually generate relatively clear fingerprint information on the screen, it can When a long press operation is detected based on the screen, fingerprint information generated by the long press operation is collected.

When the touch operation is a sliding operation and the sliding duration of the sliding operation is longer than the first preset duration, it means that the user's finger stays on the screen for a long time when performing the sliding operation, and relatively clear fingerprint information can be generated on the screen. Therefore, when a long-time sliding operation is detected based on the screen, fingerprint information generated by the sliding operation can be collected.

In order to further improve the accuracy of fingerprint collection, when the touch duration is longer than the first preset duration, it can also be judged whether the touch operation is a specified touch operation, and when the touch operation is a specified touch operation, then The fingerprint information generated by the touch operation is collected, and when the touch operation is not the specified touch operation, the fingerprint information generated by the touch operation is not collected.

Wherein, the designated touch operation is a touch operation with an operation frequency greater than a preset frequency among various types of touch operations, that is, a touch operation frequently used by a user with a relatively high operation frequency. That is to say, the operation frequency of various types of touch operations can be counted in advance, and then the touch operation whose operation frequency is greater than the preset frequency is determined as the specified touch operation, and only the fingerprint generated by the specified touch operation Information is collected.

Since the operation of the specified touch operation with high operating frequency is usually relatively stable, the accuracy of fingerprint collection can be improved by only collecting the fingerprint information generated by the specified touch operation with high operating frequency, and the power consumption of collection can be saved. .

Specifically, when the touch duration is longer than the first preset duration, collecting the fingerprint information generated by the touch operation includes the following two implementations:

The first implementation method: when the touch operation is a press operation and the press duration of the press operation is longer than the first preset duration, determine that the press operation is a long press operation; when the long press operation is a specified long press operation, The fingerprint information generated by the touch operation is collected through the fingerprint sensor configured at the bottom of the screen.

Wherein, the designated long-press operation is a long-press operation whose operation frequency is higher than a preset frequency among various types of long-press operations, that is, a long-press operation frequently used by the user with relatively high operation frequency.

Further, when the touch operation is a specified long-press operation, before collecting the fingerprint information generated by the touch operation through the fingerprint sensor arranged at the bottom of the screen, it also includes: counting the number of operations of various types of long-press operations , different types of long-press operations are used to achieve different functions; according to the statistical results, determine the operation frequency of each type of long-press operation; among the various types of long-press operations, the long-press operation whose operation frequency is greater than the preset frequency, Determines the specified long press action.

The multiple types of long-press operations may include long-press operations on icons, long-press operations on pictures, long-press operations on input fields, or long-press operations on blank areas of the screen, and the like.

Further, in order to improve the accuracy of the statistical results, the statistical results may also be updated during the detection process, so as to re-determine the designated long press operation.

Specifically, when the long press operation is a specified long press operation, the target type corresponding to the long press operation may also be determined; the number of operations of the long press operation of the target type is increased by a preset number of times to obtain an updated number of operations; According to the updated number of operations, the updated operation frequency of the long press operation of the target type is determined; according to the updated operation frequency, the specified long press operation is updated.

Wherein, the preset number of times can be set by the terminal or by the user, which is not limited in the embodiment of the present invention. Usually, the preset number of times can be set to 1 time, that is, every time a target type is detected When a long press operation is performed, 1 can be added to the number of operations of the long press operation of the target type, so as to obtain an updated number of operations.

The second implementation method: when the touch operation is a sliding operation and the sliding duration of the sliding operation is longer than the first preset duration, judge whether the sliding operation is a specified sliding operation; when the sliding operation is a specified sliding operation, pass The fingerprint sensor configured under the screen collects the fingerprint information generated by the touch operation.

Wherein, the specified sliding operation is a sliding operation whose operation frequency is higher than a preset frequency among various types of sliding operations, that is, a sliding operation frequently used by a user with a relatively high operation frequency.

Specifically, when the sliding operation is a designated sliding operation, before collecting the fingerprint information generated by the touch operation, it may also include: counting the number of operations of various types of sliding operations, and different types of sliding operations are used to realize Different functions; determine the operation frequency of each type of sliding operation according to the statistical results; determine the sliding operation whose operating frequency is greater than a preset frequency among the multiple types of sliding operations as the specified sliding operation.

Wherein, the multiple types of sliding operations include sliding operations on icons, sliding operations on pictures, or sliding operations on blank areas of the screen. Wherein, the sliding operation on the icon may include the sliding operation on the unlock icon and the like.

Further, in order to improve the accuracy of the statistical results, the statistical results may also be updated during the detection process, so as to re-determine the specified sliding operation.

Specifically, when the sliding operation is a specified sliding operation, the target type corresponding to the sliding operation can also be determined; the number of operations of the sliding operation of the target type is increased by a preset number of times to obtain an updated number of operations; according to the updated The number of times of operation determines the updated operation frequency of the sliding operation of the target type; according to the updated operating frequency, the specified sliding operation is updated.

Wherein, the preset number of times can be set by the terminal or by the user, which is not limited in the embodiment of the present invention. Usually, the preset number of times can be set to 1 time, that is, every time a target type is detected During the sliding operation, the operation count of the sliding operation of the target type can be increased by 1, so as to obtain the updated operation count.

Note that, in the embodiment of the present invention, the fingerprint information generated by the touch operation can be collected through the fingerprint sensor disposed under the screen. That is, a fingerprint sensor is disposed under the screen of the terminal, and the fingerprint sensor is used to collect fingerprint information generated at a corresponding position on the screen.

Specifically, when the touch operation is a long press operation, the fingerprint information generated by the touch operation can be collected through the fingerprint sensor corresponding to the long press area of the long press operation; The fingerprint sensor corresponding to the sliding area of the sliding operation collects the fingerprint information generated by the touching operation.

Further, the terminal may be configured with a fingerprint sensor under a partial area of the screen, or may be configured with a fingerprint sensor under all areas of the screen, which is not limited in this embodiment of the present invention. When a fingerprint sensor is arranged under a partial area of the screen, only when a touch operation is detected in the partial area, can the fingerprint information generated by the touch operation be collected by the fingerprint sensor arranged under the partial area. When fingerprint sensors are arranged under all areas of the screen, when a touch operation is detected in any area of the screen, the fingerprint information generated by the touch operation can be collected by the fingerprint sensor arranged under the area.

Further, collecting the fingerprint information generated by the touch operation through the fingerprint sensor arranged under the screen further includes: determining the touch area of the touch operation on the screen, activating the fingerprint sensor arranged under the touch area, and The fingerprint sensor disposed below the touch area collects fingerprint information generated by the touch operation. By only activating the fingerprint sensor in the corresponding area to collect fingerprint information, the power consumption of the fingerprint sensor can be saved, thereby saving the power consumption of the terminal.

It should be noted that the embodiment of the present invention is only described by taking the fingerprint information generated by the touch operation when the touch duration of the touch operation is longer than the first preset duration as an example for illustration, and in another embodiment In this method, when a touch operation is detected based on the screen, the touch duration of the touch operation may not be determined, and the fingerprint information generated by the touch operation may be directly collected.

Step 203: Determine the collection duration of the collected fingerprint information.

In the embodiment of the present invention, in order to improve the accuracy, after the fingerprint information is collected, the collection duration of the collected fingerprint information can be determined first, that is, after the collection of the fingerprint information generated by the touch operation is completed, the time period from the start of collection can be determined. The collection time between the time when the collection is completed.

Step 204: When the collection duration is greater than or equal to a third preset duration, match the collected fingerprint information with the stored fingerprint information.

In addition, when the collection duration is shorter than the third preset duration, the collected fingerprint information may also be discarded, that is, the collected fingerprint information is not matched with the stored fingerprint information.

Wherein, the third preset duration may be set by default by the terminal, or may be set by a user, which is not limited in this embodiment of the present invention. For example, the third preset duration may be 0.5 second or 1 second.

Wherein, the stored fingerprint information is fingerprint information pre-stored by the terminal for fingerprint verification, and the stored fingerprint information may include fingerprint information of one or more fingers. For example, the terminal may store a fingerprint database, which includes fingerprint information of one or more fingers.

When the collection time is greater than or equal to the third preset time, it means that the collected fingerprint information is relatively accurate; when the collection time is less than the third preset time, it means that the collected fingerprint information may be vague and cannot accurately indicate the user's fingerprint. Therefore, by only matching the collection duration greater than or equal to the third preset duration with the stored fingerprint information, invalid matching operations can be avoided and terminal power consumption can be reduced.

Specifically, matching the collected fingerprint information with the stored fingerprint information includes: calculating the fingerprint similarity between the collected fingerprint information and the stored fingerprint information; when the fingerprint similarity is greater than or equal to a preset similarity threshold, determining The collected fingerprint information matches the stored fingerprint information; when the fingerprint similarity is less than a preset similarity threshold, it is determined that the collected fingerprint information does not match the stored fingerprint information.

Wherein, the preset similarity threshold may be set by default by the terminal, or may be set by a user, which is not limited in this embodiment of the present invention. For example, the preset similarity threshold may be 90%, 95% and so on.

Wherein, when the collected fingerprint information matches the stored fingerprint information, it means that the fingerprint corresponding to the collected fingerprint information and the fingerprint corresponding to the stored fingerprint information are fingerprints of the same finger.

That is, the collected fingerprint information can be matched with the fingerprint information of each finger in the stored fingerprint information of at least one finger. During the matching process, the fingerprint similarity between the collected fingerprint information and the fingerprint information of each finger can be calculated. , when the fingerprint similarity is greater than or equal to the preset similarity threshold, it can be determined that the collected fingerprint information matches the fingerprint information of the finger, and it is determined that the fingerprint corresponding to the collected fingerprint information and the fingerprint corresponding to the fingerprint information of the finger are fingerprints of the same finger.

It should be noted that, the embodiment of the present invention is only illustrated by matching the collected fingerprint information with the stored fingerprint information when it is determined that the collection time of the collected fingerprint information is greater than or equal to the third preset time length. In another embodiment, after the fingerprint information is collected, the collection time period may be determined, and the collected fingerprint information may be directly matched with the stored fingerprint information.

Step 205: When the collected fingerprint information matches the stored fingerprint information, update the stored fingerprint information based on the collected fingerprint information.

Wherein, updating the stored fingerprint information based on the collected fingerprint information refers to splicing the collected fingerprint information with the stored fingerprint information to complete the stored fingerprint information.

Specifically, updating the stored fingerprint information based on the collected fingerprint information may include: determining, from the collected fingerprint information, partial fingerprint information different from the stored fingerprint information; combining the different partial fingerprint information with the stored splice the fingerprint information; replace the spliced fingerprint information with the stored fingerprint information.

In this way, in the process of using the terminal, the user can continuously improve and relearn the stored fingerprint information by collecting new fingerprint information generated on the screen, so that the stored fingerprint information can include all fingerprints of the corresponding finger. data, which in turn can improve the sensitivity of subsequent fingerprint identification.

In the embodiment of the present invention, when a touch operation is detected based on the screen, the fingerprint information generated by the touch operation can be collected through the fingerprint sensor configured under the screen, and when the collected fingerprint information matches the stored fingerprint information, The stored fingerprint information is updated based on the collected fingerprint information, so that the stored fingerprint information can be continuously improved and relearned through the fingerprint information generated by the touch operation, thereby improving the accuracy and sensitivity of fingerprint identification.
