Refer to the schematic flow diagram that Fig. 2, Fig. 2 are a kind of fingerprint identification methods that another embodiment of the present invention provides.This In embodiment, the executive agent of fingerprint identification method is terminal, and terminal has fingerprint identification function.Terminal can be mobile phone, flat board The mobile terminals such as computer.Fingerprint identification method as shown in Figure 2 can comprise the following steps that
S201: obtain the first history fingerprint feature information of described user input, and determine that described first history fingerprint is special The predeterminable area that reference breath is corresponding.
Finger print identifying function, and the finger of input reference are opened in the interface that arranges that user carries out authentication beforehand through fingerprint During stricture of vagina characteristic information, terminal obtains, by fingerprint sensor, the fingerprint image that each finger of user is corresponding, and from fingerprint image Obtain the fingerprint feature information of the reference of user's input, and be identified as the fingerprint feature information preset.Terminal can will be used The fingerprint feature information that same finger that family repeatedly inputs is corresponding is combined into one, and to press finger, to store each finger the most corresponding Complete fingerprint feature information.
Wherein, fingerprint sensor can be capacitance sensor or optical sensor, but is not limited to this, it is also possible to for other Fingerprint sensor, does not limits.
The fingerprint image comprising complete finger print characteristic information corresponding for each finger is divided at least two and presets by terminal Region.At least two predeterminable area can include zone line and marginal area, and marginal area can include the first marginal zone Territory and the second marginal area.Fingerprint feature information includes the characteristic informations such as the starting point of fingerprint, terminal, binding site and bifurcation.
Terminal obtains the first history fingerprint feature information that user inputs in the first preset time period, and determines that first goes through The each self-corresponding predeterminable area of fingerprint feature information of each finger that history fingerprint feature information is comprised, and statistic mixed-state To the number of times that the fingerprint feature information of each predeterminable area of each finger is corresponding.
Wherein, the first preset time period can be one week, but is not limited to this, it is also possible to is set to other values, specifically may be used It is configured according to actual needs.
S202: determine each described pre-according to the number of times of each predeterminable area corresponding to described first history fingerprint feature information If each self-corresponding matching degree threshold value in region.
Terminal, according to the number of times of each predeterminable area corresponding to the first history fingerprint feature information, determines that each predeterminable area is corresponding Matching degree threshold value.Wherein, on the premise of can guarantee that the uniqueness of finger print identifying, the number of times that predeterminable area is corresponding is the highest, should The matching degree threshold value that predeterminable area is corresponding is the lowest.
Such as, predeterminable area includes the zone line preset, the first default marginal area and the second default edge Corresponding initial of region, uniqueness and the safety that matching degree can ensure finger print identifying more than 60%, and each predeterminable area When matching degree threshold value is 90%, terminal check detects the fingerprint characteristic letter of default zone line in the first preset time period The number of times of breath is more than the number of times of the fingerprint feature information of the first marginal area preset, and the fingerprint of the first default marginal area is special When the number of times of reference breath is more than the number of times of fingerprint feature information of the second marginal area preset, terminal recognition is that user habit is adopted Carrying out authentication with the fingerprint feature information of default zone line, the first default marginal area, terminal is by default Between matching degree threshold value corresponding to region be 70%, the matching degree threshold value that the first marginal area of presetting is corresponding is 80%, presets The matching degree threshold value that second marginal area is corresponding is 90% (continuing to have).
Wherein, the span of the matching degree threshold value that this predeterminable area is corresponding is more than or equal to 60%, and less than 90%.
Alternatively, terminal can also arrange safe class, each safe class according to the number of times that each predeterminable area is corresponding A corresponding matching degree threshold value.Wherein, the corresponding numbers range of each safe class, the matching degree of the highest correspondence of safe class Threshold value is the highest.
Such as, detect that, when the number of times of the fingerprint feature information that predeterminable area is corresponding is 1～5 time, this predeterminable area is corresponding Safe class be one-level, matching degree threshold value corresponding to one-level safe class is 90%；The fingerprint that predeterminable area is corresponding detected When the number of times of characteristic information is 6～15 times, the safe class that this predeterminable area is corresponding is two grades, secondary safety grade corresponding Degree of joining threshold value is 80%；Detect when the number of times of the fingerprint feature information that predeterminable area is corresponding is 16～30 times, this predeterminable area Corresponding safe class is three grades, and matching degree threshold value corresponding to three level security grades is 70%.It is understood that each safety The numbers range that grade is corresponding, matching degree threshold value corresponding to each safe class all can be configured, herein according to actual needs Do not limit.
S203: if the triggering command being carried out authentication by fingerprint being detected, the first fingerprint obtaining user's input is special Reference ceases.
Terminal is when the triggering command being carried out authentication by fingerprint being detected, and terminal is obtained by fingerprint sensor and uses The fingerprint image at family, and from fingerprint image, obtain the first fingerprint feature information of user's input.
Wherein, the triggering command being carried out authentication by fingerprint may is that terminal has preset unlocked by fingerprint function, detection Interface input fingerprint is being unlocked, it is intended to released the screen locking of terminal by finger print identifying to user；It can also be terminal detection Fingerprint is inputted, it is intended to realize payment function by finger print identifying, but be not limited to this, it is also possible to be other in payment interface (such as, terminal detects that user clicks on the application icon on main interface/desktop to triggering command, it is intended to opened by finger print identifying The application that this application icon dynamic is corresponding), do not limit.
S204: determine the predeterminable area that described first fingerprint feature information is corresponding, and obtain the described predeterminable area determined Corresponding matching degree threshold value.
Owing to user's finger is limited with the contact area of fingerprint sensor, the fingerprint image of each finger is divided at least two Individual predeterminable area, the fingerprint feature information that user inputs every time simply accounts for the preset fingerprint feature prestored that this finger is corresponding A portion of information；Therefore, terminal is after the first fingerprint feature information getting user's input, in conjunction with local data base The data preserved determine the predeterminable area that the first fingerprint feature information is corresponding, and obtain corresponding the presetting of the first fingerprint feature information Matching degree threshold value corresponding to region.
Alternatively, terminal arranges the safe class that predeterminable area is corresponding, and arranges matching degree threshold value for each safe class Time, step S204 may include that the safe class of the predeterminable area determining that described first fingerprint feature information is corresponding；Obtain described The matching degree threshold value that the safe class that determines is corresponding.
Owing to the fingerprint image comprising complete finger print characteristic information corresponding for each finger is divided at least two by terminal Predeterminable area, therefore, terminal is when getting the first fingerprint feature information, and the preset fingerprint preserved in traversal local data base is special Reference breath determines the predeterminable area that the first fingerprint feature information is corresponding, and determines the safe class that this predeterminable area is corresponding, and Obtain the matching degree threshold value that this safe class is corresponding.
Alternatively, when the first fingerprint feature information correspondence at least two predeterminable area, step S204 can also include: really At least two predeterminable area that fixed described first fingerprint feature information is corresponding, and it is the most right to obtain described at least two predeterminable area The matching degree threshold value answered.
When the first fingerprint feature information correspondence at least two predeterminable area, terminal determines that the first fingerprint feature information is corresponding At least two predeterminable area, and obtain each self-corresponding matching degree threshold value of at least two predeterminable area.
Such as, zone line that the first fingerprint feature information correspondence is preset and the first default marginal area, obtain pre- If matching degree threshold value corresponding to zone line, and obtain the matching degree threshold value that the first marginal area preset is corresponding.
Such as, getting matching degree threshold value corresponding to default zone line is 70%, and gets default first The matching degree threshold value that marginal area is corresponding is 80%.
S205: if described first fingerprint feature information and the matching degree of the fingerprint feature information preset are more than or equal to described The described matching degree threshold value obtained, is identified as finger print identifying success.
The first fingerprint feature information got is compared by terminal with the fingerprint feature information prestored, and calculates first Matching degree/similarity between fingerprint feature information and the fingerprint feature information prestored, and judge that this matching degree/similarity is The no matching degree threshold value being more than or equal to corresponding to the predeterminable area that the first fingerprint feature information is corresponding.
Terminal is confirming that first fingerprint feature information matching degree with the fingerprint feature information preset is more than or equal to obtaining Matching degree threshold value time, be identified as finger print identifying success.Wherein, the matching degree threshold value of acquisition is that the first fingerprint feature information is corresponding The matching degree threshold value corresponding to predeterminable area.
Alternatively, when the first fingerprint feature information correspondence at least two predeterminable area, step S205 can also include: if Described first fingerprint feature information of each predeterminable area is all higher than with the matching degree of the fingerprint feature information preset or equal to each Self-corresponding described matching degree threshold value, is identified as finger print identifying success.
Such as, the first fingerprint feature information correspondence preset zone line and the first default marginal area, and obtain The matching degree threshold value corresponding to the zone line preset is 70%, and gets the coupling that the first default marginal area is corresponding Degree threshold value is when being 80%, the first fingerprint feature information that zone line that terminal judges is preset is corresponding and the fingerprint characteristic letter preset Whether matching degree/the similarity of breath is more than or equal to 70%, and judges the first fingerprint that the first default marginal area is corresponding Whether characteristic information is more than or equal to 80% with the matching degree/similarity of the fingerprint feature information preset.
Terminal is confirming the first fingerprint feature information that default zone line is corresponding and the fingerprint feature information preset Matching degree/similarity is more than or equal to 70%, and judges the first fingerprint feature information that the first default marginal area is corresponding When being more than or equal to 80% with the matching degree/similarity of default fingerprint feature information, it is identified as finger print identifying success.
It is understood that terminal is when confirming finger print identifying success, corresponding the presetting of finger print identifying success can be performed Operation.Predetermined registration operation can be to unlock, pay, start application program etc..
Such as, terminal is when confirming that user attempts by finger print identifying removing screen locking, and terminal is confirming finger print identifying After success, it is unlocked operation.
Terminal is when confirming that user attempts to be paid by finger print identifying, and terminal, after confirming finger print identifying success, is held Row delivery operation.
S206: obtain the second history fingerprint feature information of described user input, and determine that described second history fingerprint is special The predeterminable area that reference breath is corresponding.
Terminal obtains the second history fingerprint feature information that user inputs in the second preset time period, and determines that second goes through The each self-corresponding predeterminable area of fingerprint feature information of each finger that history fingerprint feature information is comprised, and statistic mixed-state To the number of times that the fingerprint feature information of each predeterminable area of each finger is corresponding.
Wherein, the second preset time period can be one week, but is not limited to this, it is also possible to is set to other values, specifically may be used It is configured according to actual needs.
S207: adjust each described pre-according to the number of times of each predeterminable area corresponding to described first history fingerprint feature information If each self-corresponding matching degree threshold value in region.
Terminal is according to each predeterminable area corresponding to the second history fingerprint feature information obtained in the second preset time period Number of times, adjust the matching degree threshold value that each predeterminable area is corresponding.Wherein, on the premise of can guarantee that the uniqueness of finger print identifying, The number of times that predeterminable area is corresponding is the highest, and the matching degree threshold value that this predeterminable area is corresponding is the lowest.Second preset time period can be one Week, but it is not limited to this, it is also possible to it is set to other values, specifically can be configured according to actual needs.
For example, it is assumed that: predeterminable area includes zone line, the first default marginal area and default second preset Marginal area, the matching degree threshold value that default zone line is corresponding is 70%, the matching degree that the first default marginal area is corresponding Threshold value is 80%, and the matching degree threshold value that the second default marginal area is corresponding is 90%；
So, terminal check detects the fingerprint feature information of the second default marginal area in the second preset time period Number of times more than the number of times of fingerprint feature information of the first marginal area preset, and the fingerprint of the first marginal area preset is special When the number of times of reference breath is more than the number of times of fingerprint feature information of the zone line preset, it is pre-that terminal recognition is that user habit uses If the second marginal area, the fingerprint feature information of the first default marginal area carry out authentication, terminal is by default The matching degree threshold value that two marginal areas are corresponding is 70%, and the matching degree threshold value that the second default marginal area is corresponding is 80%, in advance If matching degree threshold value corresponding to zone line be 90%.
Certainly, zone line, the first default marginal area and the second default marginal area preset are the most corresponding Adjustment after matching degree threshold value can also be other values, as long as ensure finger print identifying uniqueness (such as, matching degree is big In 60% uniqueness that can ensure finger print identifying and safety) under premise, the number of times that predeterminable area is corresponding is the highest, this preset areas Matching degree threshold value corresponding to territory is the lowest.
Alternatively, terminal can also adjust safe class, each safe class according to the number of times that each predeterminable area is corresponding A corresponding matching degree threshold value.Wherein, the corresponding numbers range of each safe class, the matching degree of the highest correspondence of safe class Threshold value is the highest.
Such as, detect that, when the number of times of the fingerprint feature information that predeterminable area is corresponding is 1～5 time, this predeterminable area is corresponding Safe class be one-level, matching degree threshold value corresponding to one-level safe class is 90%；The fingerprint that predeterminable area is corresponding detected When the number of times of characteristic information is 6～15 times, the safe class that this predeterminable area is corresponding is two grades, secondary safety grade corresponding Degree of joining threshold value is 80%；Detect when the number of times of the fingerprint feature information that predeterminable area is corresponding is 16～30 times, this predeterminable area Corresponding safe class is three grades, and matching degree threshold value corresponding to three level security grades is 70%.It is understood that each safety The numbers range that grade is corresponding, matching degree threshold value corresponding to each safe class all can be configured, herein according to actual needs Do not limit.
