Extract the characteristic point in described fingerprint；According to the characteristic point extracted described in pre-stored fingerprint comparison, to obtain the similar of described fingerprint
Property score, and described similarity score more than predetermined threshold value time generate identify successful result.
S104, when described fingerprint mates with described pre-stored fingerprint and described fingerprint touches the screen of described terminal, enter
Row unlocking screen.
Optionally, after described terminal carries out unlocking screen, described method also includes: obtains and uses frequency more than predetermined threshold value
Application program；Described use frequency is presented on screen more than the application program of predetermined threshold value according to preset order by described terminal
On for user select.
Wherein, use frequency more than the application program of predetermined threshold value can be QQ, wechat, Taobao, Baidu, note, word,
Excel, Wang Wang, Fetion or other application programs.
It can be seen that in the scheme of the embodiment of the present invention, when the distance detected between object and the screen of terminal is less than
During predeterminable range, obtain the image of described object；When the image identifying described object comprises fingerprint, extract described fingerprint；
Judge whether described fingerprint mates with pre-stored fingerprint；When described fingerprint mates with described pre-stored fingerprint and described fingerprint touches institute
When stating the screen of terminal, carry out unlocking screen.It is hereby understood that by implementing the technical scheme that the present invention provides, it is possible to promoting
While Terminal security, it is also possible to promote and unlock speed, thus promote Consumer's Experience.
Refer to the flow process of method that Fig. 2, Fig. 2 are the another kind of unlocked by fingerprints that an alternative embodiment of the invention provides show
It is intended to.Wherein, as in figure 2 it is shown, the method for another kind of unlocked by fingerprint that an alternative embodiment of the invention provides can include with

N1, described n2 are positive integer.
S203, the fingerprint that described user inputs is set to pre-stored fingerprint.
Specially the fingerprint scanned is deposited it is understood that the fingerprint that described user inputs to be set to pre-stored fingerprint
Store up in the file of pre-stored fingerprint in terminal or in data base.
S204, when the distance detected between object and the screen of terminal less than predeterminable range time, obtain described object
Image.
Interchangeable, described terminal can also start mirror image application, and described mirror image is used for presenting and is mapped in described end
Picture on end screen, wherein, described picture comprises the image of described object；Described terminal obtains object from described picture
Image.
S205, when the image identifying described object comprises fingerprint, extract described fingerprint.
Wherein it is desired to it is noted that terminal can store the template of multiple fingerprint, it is judged that in the image of this object whether
Comprise the template of fingerprint.When comprising the template of fingerprint in the image of this object, then user may be unlocked.
S206, judge whether described fingerprint mates with pre-stored fingerprint.
Wherein, this fingerprint can be the fingerprint of any one finger of this user.
It is understood that this fingerprint mates the minutia of the fingerprint referring to user's input with described pre-stored fingerprint
(such as referring to that end refers to the lines on abdomen) reaches a certain threshold value (such as with the similarity of the minutia of described pre-stored fingerprint
98%) finger print information of user's input and described pre-stored fingerprint information match are i.e. assert.
Wherein it is possible to be understood by, the unsharp situation of fingerprint identified due to existence, this fingerprint and the described finger that prestores
Stricture of vagina matching degree may be less than absolutely.
Wherein, the detailed process that described fingerprint carries out mating with pre-stored fingerprint is also included: described fingerprint is pre-with multiple
Deposit fingerprint to mate, determine the pre-stored fingerprint the highest with described fingerprint similarity；Judge that described fingerprint and similarity are the highest
Whether pre-stored fingerprint mates.
Wherein, described judge whether described fingerprint mates with pre-stored fingerprint, specifically include: according to described fingerprint module fingerprint
Identify n2 the bottom data value that n2 normal induction electrode of module collects, determine the n1 that n1 abnormal induction electrode is corresponding
Individual with reference to bottom data value；Fingerprint image is generated with reference to bottom data value according to described n2 bottom data value and described n1；
Extract the characteristic point in described fingerprint；According to the characteristic point extracted described in pre-stored fingerprint comparison, to obtain the similar of described fingerprint
Property score, and described similarity score more than predetermined threshold value time generate identify successful result.
S207, when described fingerprint mates with described pre-stored fingerprint and described fingerprint touches the screen of described terminal, enter
Row unlocking screen.
S208, acquisition use the frequency application program more than predetermined threshold value.
Wherein, described application program can be QQ, wechat, Baidu, map or other application programs.
S209, according to preset order, described use frequency is presented on the screen more than the application program of predetermined threshold value
Select for user.
Use frequency big it can be seen that the scheme of the embodiment of the present invention has expanded the step arranging pre-stored fingerprint with presenting
Step in the application program of predetermined threshold value.It is hereby understood that by implementing the technical scheme that the present invention provides, it is possible to promote terminal
While safety, it is also possible to promote Consumer's Experience.
