Specifically, to store at least one identification method and identification method corresponding with safety level information for mobile terminal Relationship, for lower security level, corresponding identification method is relatively simple, such as can be the finger of any one finger of identification Vein image, for higher security level, for identification method it is complex, such as can be while identifying more fingers Finger vein image, can also be other than identification refers to vein image, also to be assisted in identifying, it is all logical that only there are many identifications Out-of-date, just determination identifies successfully.

Step 203, obtain user by the hand vein recognition module first refers to vein image.

Specifically, mobile terminal is provided with hand vein recognition module, finger is placed in the pickup area of mobile terminal by user, is moved Dynamic terminal obtains the first of user by hand vein recognition module and refers to that vein image, the first finger vein image can be the thumb of user Refer to, the finger vein image of any one finger in index finger, middle finger, ring finger and little finger.

Step 204, corresponding with first identification method finger vein template of the first finger vein image is carried out pair Than to judge whether the first finger vein image identifies success.

Specifically, mobile terminal stores multiple finger vein templates, finger vein template including same user Duo Gen finger, Finger vein template of different user etc., acquisition for mobile terminal finger vein template corresponding with the first identification method, for example, when first Identification method is when identifying the finger vein image of index finger, then the finger vein template of acquisition for mobile terminal index finger will obtain The first finger vein image and the finger vein template of index finger compare, to judge that first refers to whether vein image is identified as Function.

In a kind of possible example, the corresponding finger vein template of the first identification method then only refers to vein for first Image refers to that vein template compares with this, to judge whether to identify successfully.

In alternatively possible example, the first identification method corresponds to multiple finger vein templates, such as door lock control system Provided with multiple validated users, mobile terminal stores the finger vein template of multiple validated user, then needing to refer to first Vein image is compared with multiple finger vein template, as long as first refers to appointing in vein image and multiple finger vein template It anticipates one when referring to that vein template compares successfully, it can judge that the first finger vein image identifies successfully.

Step 205, when the first finger vein image identifies successfully, Xiang Suoshu door lock controlling terminal, which sends to unlock, to be referred to It enables, the unlocking instruction is used to indicate the door lock controlling terminal control and unlocks.

Step 304, the finger vein template of pre-stored first finger of acquisition for mobile terminal.

Step 305, mobile terminal compares the finger vein template of the first finger vein image and the first finger, to obtain First similarity.

In a kind of possible example, mobile terminal refers to that the finger vein template of vein image and the first finger carries out for first Comparison, may is that in the method for obtaining the first similarity

Analysis first refers to the characteristic point distribution of vein image；

Refer to that vein image carries out circular image interception to first according to a not concentric of M, obtains M circle and refer to vein figure Picture, the M are the integer greater than 3；

Refer to that target circle is selected in vein image refers to vein image from M circle, target circle refers to that vein image is included Characteristic point quantity be greater than M circle refer to that other circles in vein image refer to vein image；

Target circle is referred to that the finger vein template of vein image and the first finger carries out Feature Points Matching, to obtain the first phase Like degree.

As it can be seen that can also include other irrelevant informations, such as background due to referring in vein image other than comprising characteristic point Information and noise will refer to that all information for including in vein image are all compared with the finger vein template of the first finger, meeting It takes a long time and more resource, and accuracy rate may be will affect, so by that will refer to that vein image intercepts, from It is middle to choose the finger vein image most comprising characteristic point, it will be carried out comprising the most finger vein image of characteristic point and finger vein template Comparison, can save the reduced time, and it is also higher to compare accuracy rate.

In a kind of possible example, target circle is referred to that the finger vein template of vein image and the first finger carries out feature Point matching, may is that in the method for obtaining the first similarity

When target circle refers to the clarity of vein image not less than default clarity threshold, target circle is referred into vein figure All characteristic points and the finger vein template of the first finger carry out Feature Points Matching as in, to obtain the first similarity；

When target circle refers to the clarity of vein image less than default clarity threshold, target circle is referred into vein image In all characteristic point be divided into N category feature point, N is the integer greater than 1, the weighted of N category feature point setting；

The finger vein template of N category feature point and the first finger is subjected to Feature Points Matching, to obtain the first similarity.

Specifically, when obtaining the finger vein image of user, it is possible to which appearance causes since the finger vein of user is shallower The more fuzzy situation of finger vein image of acquisition, if target circle is directly referred to characteristic point all in vein image and the The finger vein template of one finger carries out Feature Points Matching, will lead to and refuses sincere higher, i.e., validated user is identified as inactive users, So need first to judge that target circle refers to whether the clarity of vein image is less than default clarity threshold, when target circle refer to it is quiet When the clarity of arteries and veins image is not less than default clarity threshold, target circle is referred to characteristic point and first all in vein image The finger vein template of finger carries out Feature Points Matching, to obtain the first similarity；

When target circle refers to the clarity of vein image less than default clarity threshold, target circle is referred into vein image In all characteristic point be divided into N category feature point, N is the integer greater than 1, the weighted of N category feature point setting, for characteristic point The weight for being distributed a kind of characteristic point setting the most intensive is maximum, is similarly distributed a kind of characteristic point dispersed the most for characteristic point The weight of setting is minimum；

The finger vein template of N category feature point and the first finger is subjected to Feature Points Matching, N number of similarity is obtained, according to N class The weight of characteristic point integrates N number of similarity, and the first similarity can be obtained.

As it can be seen that in the case where causing the finger vein image obtained more to obscure since the finger vein of user is shallower, judgement Whether clarity is less than default clarity threshold, if it is less than default clarity threshold, then characteristic point is classified and is arranged Different weights can make the accuracy rate for the similarity being calculated higher in this way, reduce refuse it is sincere.

Step 306, mobile terminal judges whether the first similarity is more than default similarity threshold.

Step 307, if the first similarity is more than default similarity threshold, it is determined that the first finger vein image identifies successfully.

Step 308, if the first similarity is no more than default similarity threshold, it is determined that first refers to that vein image identification is lost It loses.

Step 309, when the first finger vein image identifies successfully, mobile terminal, which sends to unlock to door lock controlling terminal, to be referred to It enables.

Step 310, door lock controlling terminal control is unlocked.

As can be seen that mobile terminal receives the unlocking request from door lock controlling terminal in the embodiment of the present application, unlocking is asked Class information safe to carry is sought, mobile terminal is searched matched with safety level information from least one preset identification method First identification method, obtain user first refer to vein image, intercept, are therefrom chosen comprising spy to the first finger vein image The most finger vein image of sign point, will include the most finger vein image of characteristic point finger vein mould corresponding with the first identification method Plate compares, also, when referring to that vein image is more fuzzy, is classified to characteristic point and different weights is arranged, with Judge whether the first finger vein image identifies success, when the first finger vein image identifies successfully, Xiang Mensuo controlling terminal is sent Unlocking instruction, the control of door lock controlling terminal are unlocked.As it can be seen that the first of acquisition for mobile terminal user refers to quiet in the embodiment of the present application Arteries and veins image, judges whether the first finger vein image identifies success, identifies and successfully just can control unlocking, is conducive to improve door lock system The safety of system, also, will refer to that vein image intercepts, the finger vein image most comprising characteristic point is therefrom chosen, will be wrapped It compares, can save the reduced time, and compare accuracy rate with vein template is referred to containing the most finger vein image of characteristic point Also higher, in the case where causing the finger vein image obtained more to obscure since the finger vein of user is shallower, judge clarity Whether it is less than default clarity threshold then to classify to characteristic point if it is less than default clarity threshold and be arranged different Weight can make the accuracy rate for the similarity being calculated higher in this way, reduce refuse it is sincere.
