Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, is not whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As shown in fig.1, in the embodiment of the present invention, the idiographic flow of fingerprint input method is as follows：
Step 100：Gather the sample fingerprint image of the preset number of user's typing.
In practice, when using fingerprint identification technology, it is necessary to pre-save the fingerprint template of user, that is, need user advance
Typing fingerprint, in the embodiment of the present invention, the process of fingerprint module is generated primarily directed to fingerprint typing, fingerprint typing is sentenced
It is disconnected, improve its security.
Wherein, preset number, in the embodiment of the present invention and it is not limited, can be configured according to the actual requirements.
For example, preset number is 15, then, it is necessary to which user's typing 15 times, obtains 15 sample fingerprints during user's typing fingerprint
Image.
In the embodiment of the present invention, multiple sample fingerprint image is gathered, so carrying out can be more accurate when follow-up splicing judges,
And if coming from same finger, multiple sample fingerprint images are gathered, the fingerprint template that can to ultimately produce covers
Region is more, and the finger-print region of the finger can be completely covered substantially, when user carries out fingerprint recognition using the finger afterwards, nothing
By input be the finger any partial fingerprints region, can identify, user does not have to the typing position for adjusting finger print repeatedly
Put, be not in the situation of recognition failures, improve the efficiency and accuracy of fingerprint recognition.
Step 110：Whether can splice, however, it is determined that at least one if judging the sample fingerprint image of the preset number respectively
Individual sample fingerprint image can not splice, it is determined that the multiple sample fingerprint image belongs to different fingers, is alerted.
When performing step 110, specifically include：
First, whether judge the sample fingerprint image of the preset number respectively can splice.
Specifically, judge whether the multiple sample fingerprint image has the region of repetition between any two respectively, if so, then true
Fixed the multiple sample fingerprint image can splice.
That is, it can judge that sample fingerprint image whether can according to the region repeated between sample fingerprint image
Splicing, what deserves to be explained is, not implying that needs have the region of repetition between any two sample fingerprint image, such as has 3
Individual sample fingerprint image, respectively a, b and c, wherein, there is the region of repetition between a and b, the region for having repetition between b and c, but
It is the region for not having to repeat between a and c, at this moment these three sample fingerprint images a, b and c is still to splice, because a and b
Splicing, a can also splice with the spliced images of b with c, and final these three sample fingerprint images a, b and c can be spliced into one
Image.
Therefore, in the embodiment of the present invention, the sample fingerprint image for the preset number for judging to collect respectively is between any two
It is no to have repeat region, there is the region of repetition between two sample fingerprint images for referring to need sequential concatenation.
Because in fingerprint Input Process, in fact it could happen that two frames are recorded before and after same user uses same finger
The finger-print region entered, fingerprint typing position span are bigger so that there is no the situation in the region repeated between sample fingerprint image,
But for same finger, because collection sample fingerprint image is more, all finger-print regions of finger can be substantially covered, most
All it is that can splice successfully afterwards, this is also the purpose for gathering multiple sample fingerprint images, can improve the accurate of splicing judgement
Property.
Also, because the sample fingerprint image of same finger is all finally that can splice successfully, therefore, it can pass through
Multiple sample fingerprint images are gathered, judge whether this multiple sample fingerprint image can splice, to determine whether other fingers
Sample fingerprint image be mixed into.
Then, however, it is determined that at least one sample fingerprint image can not splice, it is determined that the multiple sample fingerprint image
Belong to different fingers, alerted.
In the embodiment of the present invention, multiple sample fingerprint images are collected, due to the finger-print region of a finger
Than relatively limited, whether can be spliced by this multiple sample fingerprint image and be judged, if there is at least one sample fingerprint
Image can not be spliced with other sample fingerprint images, then it is considered that the multiple sample fingerprint images collected belong to different
Finger.
Wherein it is determined that the multiple sample fingerprint image belongs to different fingers, alerted, specifically included：According to pre-
If mode, the sample fingerprint image of user's typing is prompted to belong to different fingers, typing fails and re-starts fingerprint typing.
For example, pass through voice message user.
In another example pass through text prompt user.
It can certainly use other prompting modes, in the embodiment of the present invention, and be not limited.
At this moment, however, it is determined that the multiple sample fingerprint images collected belong to different fingers, typing failure, finally also no
To fingerprint template, avoid has other mixed situations of user's finger fingerprint in typing fingerprinting process, improves fingerprint recognition
Security.
Further, it is determined that the multiple sample fingerprint image belongs to after different fingers, in addition to：Will be the multiple
Sample fingerprint image is deleted.
So, however, it is determined that the multiple sample fingerprint images collected belong to different fingers, all fingerprints that will be collected
Sample image is all deleted, and it will not be preserved, when user re-types fingerprint again, multiple fingerprint samples for collecting
This image can splice, and just be preserved so that the fingerprint template ultimately produced, will not be mixed into the fingerprint image of other fingers
Picture, it ensure that the safety and reliability of fingerprint template.
When performing step 110, in addition to：If it is determined that the multiple sample fingerprint image can splice, it is determined that described
Multiple sample fingerprint images belong to same finger, and the multiple sample fingerprint image is spliced, and obtain spliced
Sample fingerprint image, using the spliced sample fingerprint image as fingerprint template, and stored.
Wherein, can be to do the region repeated when being spliced if judging to have the region of repetition when generating fingerprint template
Covering treatment, and then by two sample fingerprint image mosaics together.
At this moment, the multiple sample fingerprint images collected can splice, using spliced sample fingerprint image as referring to
Line template, obtained fingerprint template can only identify same finger, and the fingerprint template is stored, and carry out fingerprint recognition afterwards
When, can only be typing fingerprint same finger can fingerprint recognition success, improve the security of fingerprint recognition.
So, in the embodiment of the present invention, multiple sample fingerprint images of user's typing is gathered, judge whether to splice,
If it is determined that at least one sample fingerprint image can not splice, it is determined that multiple sample fingerprint images belong to different fingers, carry out
Alarm, so, in fingerprint Input Process, to being likely to occur while the situation of the fingerprint of typing difference finger judges, if
There is the situation of the fingerprint of typing difference finger simultaneously, alerted, prompt user, may be simultaneously when solving fingerprint typing
The fingerprint of typing difference finger, causes unsafe problem.
And user can be made to re-start fingerprint typing, this typing failure, do not generate fingerprint template so that finally give birth to
Into fingerprint template may only identify same finger, ensure that the security of fingerprint template, so as to also just improve fingerprint knowledge
Other security.
Further, in the embodiment of the present invention, however, it is determined that the multiple sample fingerprint image belongs to different fingers, may be used also
Different fingers is belonged to the sample fingerprint image for only prompting typing to user, security risk be present, but still according to can splice
Sample fingerprint image and the sample fingerprint image that can not splice, generate fingerprint template.Afterwards, after user obtains prompting, if
Determine that no risk or determination are all that I is operating, then can be without re-typing, for example, user wants oneself in itself
Two fingers can be carried out fingerprint recognition, then during typing fingerprint, can distinguish the sample fingerprint image of the two fingers of typing,
Although judging to have the fingerprint image that can not splice and being prompted, user can ignore the prompting, can use afterwards this two
Individual finger carries out fingerprint recognition.If user determines to there may be risk really, it can send and re-type instruction, for example, can
To set replacement button or re-type button, user re-starts fingerprint typing, receives user's weight by clicking on the button
After new typing instruction, then the fingerprint template generated before is deleted, resurvey the sample fingerprint image of user's typing.
Further description is made to above-described embodiment using a specific application scenarios below.Referring particularly to Fig. 2
Shown, in the embodiment of the present invention, the implementation procedure of fingerprint input method is specific as follows：
Step 200：Gather the sample fingerprint image of the preset number of user's typing.
For example, fingerprint input device is punched-card machine, preset number 10, then user is in typing fingerprint on punched-card machine, often
Typing once, can prompt user's please typing again, and until collecting 10 sample fingerprint images, and then punched-card machine judges this 10
Whether sample fingerprint image belongs to same finger.
Step 201：Whether can splice, if so, then performing step if judging the sample fingerprint image of preset number respectively
202, otherwise, then perform step 204.
Step 202：Determine that the sample fingerprint image of the preset number belongs to same finger.
Step 203：The sample fingerprint image of the preset number is spliced, obtains spliced sample fingerprint image,
Using spliced sample fingerprint image as fingerprint template, and stored, and turn to and perform step 207.
Step 204：Determine that the sample fingerprint image of the preset number belongs to different fingers.
That is, however, it is determined that at least one sample fingerprint image can not splice, then it is considered that what is collected is default
The sample fingerprint image of number belongs to different fingers, it is understood that there may be risk.
Step 205：According to predetermined manner, the sample fingerprint image of user's typing is prompted to belong to different fingers, typing is lost
Lose and re-start fingerprint typing.
At this moment alerted, user can be prompted, user is re-typed fingerprint, improve the safety of fingerprint Input Process
Property.
For example, voice message occurs for punched-card machine, for " the sample fingerprint image of typing belongs to different fingers, and typing fails,
Please re-start fingerprint typing ", and the interface of fingerprint typing is provided, user can be recorded again by the interface of the fingerprint typing
Enter fingerprint.
Step 206：The sample fingerprint image of the preset number is deleted, and returns and performs step 200.
