Fig. 2A is the flow chart of the first fingerprint input method shown according to an exemplary embodiment, the fingerprint typing side Method is applied in terminal, and as shown in Figure 2 A, which includes the following steps.

In step 201, the finger print data of user is acquired.

Finger print data includes at least relative position and relative distance between the characteristic point and each characteristic point of fingerprint, the spy Sign point includes starting point, terminal, binding site and the bifurcation of streakline etc. of fingerprint, and this embodiment is not limited.

In step 202, whether detection finger print data includes overlapping with the finger print data deposited in fingerprint template data Overlapped data.

When terminal detects that finger print data includes and the equitant overlapping number of the finger print data deposited in fingerprint template data According to when, execute step 203；It include mutually be overlapped with the finger print data deposited in fingerprint template data when terminal detects finger print data not When folded overlapped data, which is added in fingerprint template data, step 201 is continued to execute.

Fingerprint template data include the finger print data for the user that terminal acquires every time.When terminal acquires the finger of user for the first time When line data, this step can not be executed, the directly finger print data by the acquisition for the first time is updated into fingerprint template data.

Overlapped data refers to that fingerprint template data have at least two identical characteristic points, and fingerprint template with finger print data It is opposite between identical characteristic point in the relative position and the finger print data between the identical characteristic point in data Position is identical；Relative distance between the identical characteristic point in fingerprint template data in the finger print data this is identical Relative distance between characteristic point is equal.

Please refer to Fig. 2 B, it is assumed that the finger print data 21 of terminal acquisition includes binding site 22 and bifurcation 23, and binding site 22 exists The upper right side of bifurcation 23 and the distance between binding site 22 and bifurcation 23 are 0.2cm, and fingerprint template data 24 include combining Point 22 and bifurcation 23, and binding site 22 bifurcation 23 upper right side and the distance between binding site 22 and bifurcation 23 be 0.2cm, then the overlapped data of finger print data 21 and fingerprint template data 24 is the phase of binding site 22 and bifurcation 23 and the two To position and relative distance.

In step 203, when finger print data includes equitant overlapping with the finger print data deposited in fingerprint template data When data, determine whether finger print data is entirely overlapped data.

When finger print data is entirely overlapped data, illustrate user's typing before finger print data, at this point, executing Step 205；When finger print data is not all overlapped data, step 204 is executed.

In step 204, if finger print data is not all overlapped data, by the data in finger print data in addition to overlapped data It updates in fingerprint template data, continues to execute step 201.

In order to save the memory space of terminal storage fingerprint template data occupancy, in the present embodiment, terminal is only by fingerprint number Data in addition to overlapped data are updated into fingerprint template data, in this way, terminal can only store a overlapped data, solution The problem of all finger print datas of terminal storage of having determined lead to terminal storage at least two parts of overlapped datas, waste memory space.

In the first implementation, terminal updates the data in finger print data in addition to overlapped data to fingerprint template In data, comprising: delete the overlapped data in finger print data, the data in finger print data in addition to overlapped data are updated to finger In line template data.

In the second implementation, terminal updates the data in finger print data in addition to overlapped data to fingerprint template In data, comprising: delete the overlapped data in fingerprint template data, and will be in the overlapped data and finger print data in finger print data Data in addition to overlapped data are updated into fingerprint template data.

In the third implementation, finger print data further includes the image data of fingerprint, at this point, terminal will be in finger print data Data in addition to overlapped data are updated into fingerprint template data, comprising: compare corresponding to finger print data overlapped data the Second image resolution ratio corresponding to overlapped data in one image resolution ratio and fingerprint template data；When the first image resolution ratio is low When the second image resolution ratio, the overlapped data in finger print data is deleted, and by the number in finger print data in addition to overlapped data According to update into fingerprint template data；When the first image resolution ratio is higher than the second image resolution ratio, fingerprint template data are deleted In overlapped data, and by finger print data overlapped data and finger print data in data in addition to overlapped data update to finger In line template data.

Terminal by finger print data and fingerprint template data there are when overlapped data, delete corresponding image resolution ratio compared with The higher overlapped data of corresponding image resolution ratio is stored in fingerprint template data, improves template by low overlapped data The quality of the corresponding image of finger print data.

Optionally, terminal can be with the corresponding image of data of the real-time display in addition to overlapped data, so that user is real-time It checks fingerprint typing situation, improves fingerprint efficiency of inputting.

In step 205, if finger print data is entirely overlapped data, determine that fingerprint template data are the complete finger print of user Template data stops acquisition finger print data.

Due to when finger print data is entirely overlapped data, the terminal typing finger of the corresponding user of the fingerprint The probability of whole region is higher, and therefore, terminal determines that fingerprint template data are user when finger print data is entirely overlapped data Complete finger print template data, at this point, terminal stop acquisition finger print data, that is, this fingerprint typing process terminates.

Optionally, determine that fingerprint template data are the accuracy of the complete finger print template data of user to improve terminal, When finger print data is entirely overlapped data, terminal detection finger print data is entirely whether the number of overlapped data reaches default time Number.If the number that finger print data is entirely overlapped data is not up to preset times, terminal display reminding information, the prompt information For prompting user to replace the typing region of finger, step 201 is executed.If the number that finger print data is entirely overlapped data reaches Preset times, terminal determine that fingerprint template data are the complete finger print template data of user, stop acquisition finger print data.

Optionally, when finger print data is entirely overlapped data, it is lower that terminal also will be deleted corresponding image resolution ratio The higher overlapped data of corresponding image resolution ratio is stored in fingerprint template data by overlapped data.

Optionally, user replaces different fingers when carrying out this fingerprint typing in order to prevent, and terminal is caused to cannot get Finger print data with overlapped data, need not stop acquire finger print data the problem of, terminal acquire user finger print data when, Whether the number that can detecte acquisition finger print data reaches frequency threshold value, when the number of acquisition finger print data reaches frequency threshold value When, show typing error message, and terminate this fingerprint typing process, the typing error message is for prompting user's typing extremely The finger print data of few two fingers.

Optionally, Fig. 3 is the flow chart of second of fingerprint input method shown according to an exemplary embodiment, the fingerprint Input method is applied in terminal, as shown in figure 3, after step 202, which includes the following steps.

In step 206, it is not weighed mutually when finger print data includes overlapped data, and is included in acquisition in fingerprint template data When folded two groups of finger print datas, determine whether overlapped data is be overlapped with two groups of finger print datas.

The two groups of finger print datas not overlapped when acquisition refer to terminal when acquiring finger print data, the finger print data and current Template data in any one group of finger print data overlapped data is all not present.

If terminal determine overlapped data not and be with two groups of finger print datas it is be overlapped when, illustrate the fingerprint number of this acquisition According to not by the two groups of fingerprint data splicings not overlapped when acquiring in fingerprint template data, together, fingerprint template data may It is imperfect, at this point, executing step 207；If overlapped data and two groups of finger print datas are be overlapped, illustrate the fingerprint number of this acquisition According to not by the two groups of fingerprint data splicings not overlapped when acquiring in fingerprint template data, together, fingerprint template data may It is complete, at this point, executing step 208.

In step 207, if overlapped data be not it is be overlapped with two groups of finger print datas, will in finger print data except overlapping number Data except are updated into fingerprint template data, execute step 201.

Since when overlapped data is not be overlapped with two groups of finger print datas, template fingerprint data may be imperfect, therefore, Terminal continues to acquire finger print data.

In a step 208, if overlapped data and two groups of finger print datas are be overlapped, will in finger print data except overlapped data it Outer data are updated into fingerprint template data, are determined that fingerprint template data are the complete finger print template data of user, are stopped adopting Collect finger print data.

Since in overlapped data and be overlapped two groups of finger print datas, fingerprint template data may be the complete finger of user Line data, therefore, terminal determine that fingerprint template data are the complete finger print template data of user, stop acquisition finger print data.

Optionally, determine that fingerprint template data are the accuracy of the complete finger print template data of user to improve terminal, When overlapped data and be overlapped two groups of finger print datas, terminal, which detects overlapped data with two groups of be overlapped numbers of finger print data, is It is no to reach preset times.If overlapped data is not up to preset times with two groups of be overlapped numbers of finger print data, terminal continues Execute step 201.If overlapped data reaches preset times with two groups of be overlapped numbers of finger print data, terminal determines fingerprint template Data are the complete finger print template data of user, stop acquisition finger print data.

Optionally, user replaces different fingers when carrying out this fingerprint typing in order to prevent, and terminal is caused to collect Finger print data do not overlapped with template data, the terminal need not stop acquire finger print data the problem of, terminal acquisition use When the finger print data at family, whether the number that can detecte acquisition finger print data reaches frequency threshold value, when time of acquisition finger print data When number reaches frequency threshold value, typing error message is shown, and terminate this fingerprint typing process.

In the present embodiment, terminal is by when finger print data includes overlapped data, determining whether overlapped data refers to two groups Line data are overlapped, if overlapped data and two groups of finger print datas are be overlapped, by finger print data in addition to overlapped data After data are updated into fingerprint template data, determines that fingerprint template data are the complete finger print template data of user, stop adopting Collect finger print data, determines that the complete finger print template data of user provides another method of determination for terminal.

Optionally, Fig. 4 is the flow chart of the third fingerprint input method shown according to an exemplary embodiment, the fingerprint Input method is applied in terminal, as shown in figure 4, after step 202, which includes the following steps.

In step 209, it is not weighed mutually when finger print data includes overlapped data, and is included in acquisition in fingerprint template data When folded two groups of finger print datas, determine whether overlapped data is be overlapped with two groups of finger print datas, and determines whether finger print data is complete Portion is overlapped data.

If overlapped data be not it is be overlapped with two groups of finger print datas, alternatively, finger print data is not all overlapped data, then execute Step 210；If overlapped data and two groups of finger print datas are be overlapped, and finger print data is entirely overlapped data, is thened follow the steps 211。

Since user is when carrying out fingerprint typing, it will usually the typing region of mobile finger, when every in fingerprint template data Group finger print data be all stitched together, and collected finger print data and fingerprint template data it is completely overlapped when, at this point, fingerprint mould A possibility that plate data are the complete finger print template datas of user is very big, and therefore, in the present embodiment, terminal passes through while determining Whether overlapped data is be overlapped with two groups of finger print datas, and, whether finger print data is entirely overlapped data, improves determining use The accuracy of the complete finger print template data at family.

In step 210, if overlapped data is not be overlapped with two groups of finger print datas, alternatively, finger print data is not all weight Folded data, then update the data in finger print data in addition to overlapped data into fingerprint template data, continue to execute step 201。

In step 211, if overlapped data and two groups of finger print datas are be overlapped, and finger print data is entirely overlapped data, Then the data in finger print data in addition to overlapped data are updated into fingerprint template data, determine that fingerprint template data are user Complete finger print template data, stop acquisition finger print data.

Optionally, determine that fingerprint template data are the accuracy of the complete finger print template data of user to improve terminal, When overlapped data and two groups of finger print datas are be overlapped, and finger print data is entirely overlapped data, terminal detect overlapped data with Two groups of finger print datas are overlapped, and finger print data is entirely whether the number of overlapped data reaches preset times.If overlapped data It is be overlapped with two groups of finger print datas, and finger print data is entirely that the number of overlapped data is not up to preset times, then terminal continues Execute step 201.If overlapped data and two groups of finger print datas are be overlapped, and finger print data is entirely that the number of overlapped data reaches Preset times, terminal determine that fingerprint template data are the complete finger print template data of user, stop acquisition finger print data.
