Specific embodiment

In order to which the purpose of the application, technological means and advantage is more clearly understood, the application is done below in conjunction with attached drawing It is further described.

The application provides the signature authentication method of three kinds of electronic equipments, and in the first signature authentication method, correspondence is various Different input modes carries out signature enrolling respectively；In second and the third signature authentication method, in advance to different inputs The signature character of mode is analyzed, and the corresponding certification of different input modes is determined by threshold value, in certification according to corresponding The certification of input mode is carried out by threshold value.Three kinds of signature authentication methods in the application are described in detail below.In addition, It will be clear that illustrated by taking the signature authentication of a certain user as an example in the signature authentication method of the application below, In fact, the processing all same for all users.

Embodiment one：

In embodiment one, the first signature authentication method is described in detail.Specifically, this method includes：For A variety of different input modes, carry out signature enrolling respectively, and preserve the corresponding registration signature of each input mode；Recognize in signature During card, according to the input mode that user authentication is signed, registration signature corresponding with the input mode and the input label of user are selected Name is compared, so as to carry out signature authentication.

Wherein, input mode refers not only to the input mode of presentation, and refers to a kind of signature acquisition environment of synthesis, such as Signature is acquired to similarly setting spare pen, the label of signature and normal operating condition acquisition acquired under low-power consumption mode Name is discrepant in shape and speed, therefore, is inputted under low-power consumption mode with pen input and normal operating condition pen Belong to different input modes.In certain embodiments, input mode is it can be appreciated that soft acquisition mode, that is, same Under the hardware input mode of sample, registered and authentication signature using different modes such as font and direction difference.

In this signature authentication method, for the signature enrolling of any input mode, existing signature note may be used Volume mode.Each corresponding input mode, it is preset positive integer that can set at least acquisition n times registration signature sample, N.Due to Corresponding registration signature is preserved, therefore in signature authentication for multiple input modes correspondence, may be used and authentication signature The identical registration signature of input mode is compared with authentication signature input by user, so as to ensure the accuracy of signature authentication.

Corresponding above-mentioned signature authentication method, present invention also provides a kind of signature authentication devices, recognize for implementing the signature Card method.It is the concrete structure schematic diagram of the signature authentication device as shown in Figure 1, specifically includes：Signature enrolling unit 101, label Name authentication unit 102, signature engine unit 103 and signature library 104.

Wherein, signature enrolling unit 101 carries out signature enrolling, and will registration respectively for corresponding to different input modes Signature is saved in signature library 104.Different input modes can be handwriting input, pen input, touch tablet input etc..It is inputting During signature is registered, can set to separate input mode and register, can also Mixed design, but in system Portion can separate the corresponding signature of different input modes according to input mode, and corresponding corresponding input mode is noted respectively Volume, this point can be identified by alternately registration.As previously mentioned, the sample number of identical registration signature is at least N, for example, In existing signature enrolling method, the sample number needed is at least 3, is registered if different input modes are used alternatingly, The signature sample number that may lead to certain input mode is insufficient, causes registration problem, can also recognise that use by this and be somebody's turn to do The registration that input mode is signed.

Signature authentication unit 102, in signature authentication, identifying the input mode of user's signature, and in signature library 104 Middle selection is corresponding with the input mode to register signature, and the registration signature of selection and authentication signature input by user are sent to label Name engine unit 103 is compared, and carries out signature authentication according to the comparison result that signature engine unit 103 is fed back.

Signature engine unit 103, authentication signature and registration signature for signature authentication unit 102 to be sent compare Compared with, and comparison result is fed back into the signature authentication unit 102.During specific implementation, signature engine unit has the mould of most original Type function can handle various signature characters by the combination of basic member.In the data for being transmitted to signature engine unit 103, Signature authentication unit 102 can filter out certain characteristic quantities according to the characteristics of input mode, for example signature engine can handle pressure Force data, but pressure data during for certain equipment handwriting inputs is nonsensical, signature engine unit can be at this time The factor for pressure of forgoing is compared and analyzes for other characteristic variables.

Signature library 104 preserves registration signature for corresponding to input mode.Signature library can be located in electronic equipment or be distributed In formula system.

Above-mentioned is the specific implementation of the first signature authentication method and apparatus.The signature authentication method is by being directed to difference Input mode carries out signature enrolling, so as to be compared in authentication signature using the registration of corresponding input mode signature, so as to Avoid influence of the different input modes to signature authentication.

Embodiment two：

Second of signature authentication method of the application is described in detail in embodiment two.Fig. 2 is in the embodiment of the present application two The particular flow sheet of signature authentication method.As shown in Fig. 2, this method flow includes：

Step 201, corresponding one or more input modes carry out signature enrolling respectively.

Equally it is that corresponding input mode carries out when carrying out signature enrolling.It is different from the signature enrolling process of method one it Be in in this method, user can only carry out a kind of corresponding signature enrolling of input mode, naturally it is also possible to for it is a variety of not Same input mode carries out signature enrolling respectively.When selection carries out the input mode of registration signature, it is preferable that can select to sign The most M kinds input mode of name characteristic quantity carries out.For example, to register the registration signature of two kinds of input modes, can select to sign Two kinds of most input modes of characteristic quantity carry out signature enrolling；Alternatively, can also be determined according to the selection of user input mode into Row signature enrolling.

It specifically corresponds to any input mode and carries out the mode of signature enrolling and existing signature enrolling mode may be used carry out, Here it just repeats no more.

Step 202, authentication signature input by user is received, and one is selected in the registration signature of user.

After authentication signature input by user is received, the input mode of the authentication signature is identified.Carry out registration signature selection When, it is preferable that the selection registration signature identical with authentication signature input mode, i.e. one corresponding signature authentication side of preceding method Formula；Sign if there is no the registration identical with authentication signature input mode, then by system specify a registration signature or according to User's selection determines a registration signature, for signature authentication.

Step 203, the registration of selection is signed and is compared, and according to the registration of selection with authentication signature input by user Signature input mode corresponding with user authentication signature combines, and determines that corresponding certification by threshold value, passes through threshold according to the certification Value carries out signature authentication.

When the registration signature of selection is identical with the input mode of authentication signature, existing mode may be used and sign Certification.When the registration signature of selection and the input mode difference of authentication signature, i.e., the cross-certification mode in the application needs It is handled according to the analysis that advance different input modes are signed.

Different input modes are introduced first combine corresponding certification pass through threshold value.Specifically, in the method, in advance according to All optional input mode combinations corresponding with authentication signature of registration signature, calculate the corresponding certification of each input mode combination and lead to Cross threshold value.In more detail, it can determine that certification passes through threshold value in accordance with the following steps：

A, enough various representational user's signatures are acquired using all different input modes that equipment is supported Sample；Here representativeness can be user, symbol signatures, graphic signature of all ages and classes etc., and " enough " refers to, generally require at least There are 10 true signatures and 10 false signatures for imitating invasion, the signature of imitation generally comprises shape（It is static）It imitates and including shape The dynamic of shape, speed etc. is imitated；

B, the various representative user's signatures of different input modes are registered respectively.To the signature of each user Each input mode registers a signature respectively, and if any 100 users, equipment has 2 kinds of input modes, then needs registration 200 A signature；

C, it is signed using the registration of true signature, false signature and all different input modes in step a, carries out whole friendships The authentication test of fork mode and non-crossing mode, statistics obtain the corresponding various different lower positive normal opens of Verification System of input mode combination The score threshold crossed.

Wherein, score threshold can use etc. error rates（EER）Corresponding threshold value represents.Here, by authentication signature and registration The different certification of signature input mode is known as cross-certification, i.e. finger is registered with input mode A, but with another kind input mode B is authenticated；The authentication signature certification identical with registration signature input mode is known as non-crossing certification, that is, refers to and uses input mode A is registered, and is equally authenticated with input mode A.Non-crossing certification is identical with existing authentication mode.

It is combined particularly for any input mode, such as it is input mode to register signature as input mode A, authentication signature The true signature of input mode B and false signature are compared by B with the registration of input mode A signature respectively, so that it is determined that true signature Normal through score threshold；As previously mentioned, the true signature and false signature of input mode B are all multiple, therefore can obtain here To multiple score thresholds, it is counted, obtains the authentication signature of input mode B compared with the registration of input mode A signature When Verification System normal through score threshold, combine corresponding certification as corresponding input mode and pass through threshold value.It is specific to determine The mode for counting score threshold is identical with the mode of existing determining signature authentication score threshold, and the object only compared is intersecting It is different during certification.In general, the statistics score threshold of cross-certification will be less than the statistics score threshold of non-crossing certification.Threshold value can be with Be divided into different stage, corresponding different threshold value, such as it is difficult, in, easily, so as to realize the other signature authentication of classification.

D, it preserves the certification of various input modes combination that statistics obtains and signature authentication is used for by threshold value；Alternatively, according to Preset uniform threshold T combines corresponding certification to various different input modes and is normalized by threshold value, determined each Kind input mode combines corresponding weighting coefficient；

Wherein, when being normalized, target is that each input mode is combined corresponding certification by threshold value to return One turns to uniform threshold T, it is specific normalize mode can there are two types of：1st, directly to input mode combination certification by threshold value into Row weighting obtains uniform threshold T, preserves corresponding weighting coefficient；2nd, corresponding certification is combined to input mode by being related in threshold value And each signature character be weighted respectively using one group of weighting coefficient, so as to make according to after weighting signature character calculate threshold Value is equal to uniform threshold T, preserves one group of weighting coefficient corresponding to each signature character.Corresponding above two normalization mode, Obtained weighting coefficient is also classified into two classes：Corresponding single weighting coefficient is combined with input mode, alternatively, being combined with input mode The weighting coefficient combination of corresponding each signature character.

Corresponding certification is combined to above-mentioned different input modes to preserve by threshold value or weighting coefficient, is recognized for signing Card.

When specifically carrying out signature authentication, two ways may be used：

First, for preserve certification by way of threshold value, determine the registration selected in step 202 signature and it is input by user Input mode combination corresponding to authentication signature, from the certification of preservation by selecting to combine with the input mode determined in threshold value pair The registration signature of selection and authentication signature input by user are compared, and recognizing according to selection by the certification answered by threshold value Whether card passes through signature authentication by threshold decision.

2nd, for the mode of preservation weighting coefficient, if the weighting coefficient preserved corresponds to the list of input mode combination One weighting coefficient then determines the registration signature selected in step 202 and the input corresponding to authentication signature input by user first Mode combines, and selects to combine corresponding certification from the weighting coefficient of preservation with determining input mode by threshold value, then, will The registration signature of selection and authentication signature input by user are compared, and are added using the weighting coefficient compared result of selection It is compared after power with uniform threshold T, judges whether to pass through signature authentication；If the weighting coefficient preserved corresponds to input side The weighting coefficient combination of each signature character of formula combination then determines the registration signature selected in step 202 and user's input first Authentication signature corresponding to input mode combination, from the weighting coefficient of preservation selection with determine input mode combine correspondence Certification by threshold value, then, the registration signature of selection and authentication signature input by user are compared, obtain comparing knot Fruit, the comparison result include the comparison result of each signature character, and the weighting coefficient of selection is recycled to combine to each signature character Comparison result is weighted, and so as to calculate final comparison result, is finally compared final comparison result and uniform threshold T Compared with judging whether to pass through signature authentication.

For there is currently no registration signature input mode, if with the input mode input authentication signature by recognizing Card can then realize the automatic registration signature of corresponding input mode by handling as follows, sign so as to the registration of expansion system.

Step 204, when passing through signature authentication in step 203, judge whether to preserve in current system and authentication signature The identical registration signature of input mode, if it is present terminate this flow, if it does not exist, then by by authentication signature make It is preserved for registration signature sample, when identical registration signature sample number reaches N, carries out the signature enrolling of corresponding input mode.

When signature authentication by after, if system not yet preserves identical with authentication signature input mode registration signature, Then preserve authentication signature；It after if signature authentication is by n times, is carried out using N number of authentication signature of preservation as registration signature sample The signature enrolling of corresponding input mode, in this way, just preserving the registration signature identical with authentication signature input mode in system.Under It is secondary when input authentication is signed by this way again, it is possible to which that signature authentication is carried out namely using existing using non-crossing authentication mode Some modes carry out signature authentication.

Wherein, the automatic registration described in this step can be explicit or implicit, it is mentioned here explicit and It can implicitly be presented by UI.Explicitly user can be told when preserving registration signature sample；Alternatively, can also be implicitly into It goes and operates, i.e., directly save true signature, then directly by corresponding input mode when acquisition enough enough samples Registration signature is added in signature library.

So far, the signature authentication method flow in the present embodiment terminates.The present embodiment additionally provides a kind of electronic equipment Signature authentication device, the basic structure of the device is identical with Fig. 1, including：Signature enrolling unit, signature library, signature engine unit With signature authentication unit.

Wherein, the function of signature enrolling unit, signature library and signature engine unit is identical with embodiment one.Signature authentication Unit, for when carrying out signature authentication, receiving authentication signature input by user, and the user preserved in library 104 of signing Registration signature in select one, the registration of selection signature and authentication signature input by user are sent to signature engine unit 103 are compared；It is additionally operable to receive the comparison result of 103 feedback of signature engine unit, according to the registration signature of selection and user The input mode of authentication signature combines corresponding certification by threshold value, carries out signature authentication.
