Embodiment one：

As shown in figure 3, the present embodiment provides a kind of verification method, the method includes：

Step S410：The first biological characteristic of at least two is extracted from the biological information of acquisition；

Step S420：Judge the first matching characteristic with preset second biometric matches in first biological characteristic First number whether be less than the first designated value；

Step S430：If first number is less than first designated value, first matching characteristic is recorded；

Step S440：Within the first specified time, biological information described in n times is resurveyed and from the institute resurveyed State extraction third biological characteristic in biological information；The N is positive integer；

Step S450：It determines with second biometric matches in third biological characteristic and is not weighed with the first matching characteristic Second number of the second folded matching characteristic；

Step S460：Judge whether the sum of first number and second number are not less than first designated value；

Step S470：If the sum of first number and second number are not less than first designated value, it is determined that The biological information passes through verification.

Biological characteristic described in the present embodiment may include that fingerprint characteristic, iris feature, vocal print feature etc. are various and be originated from user The feature of body.

The step S410 can acquire biological characteristic by the various sensors of electronic equipment.For example, being adopted using fingerprint Storage acquires the fingerprint feature information of user；Iris is obtained using the structures such as camera or video camera acquisition user's eyes image Characteristic information acquires the sound of user using structures such as phonographic recorders, and vocal print feature information is obtained from the sound of acquisition.In step The biological characteristic will be also extracted in S410, such as the fingerprint texture feature to take the fingerprint, and extract the patterned feature of iris, extract Vocal print feature etc..

It will determine that out that the first biological characteristic extracted and preset the second biology for verification are special in the step s 420 Whether first number of the first matching characteristic of sign to match is less than the first designated value.For example, by taking fingerprint as an example, believe from fingerprint The crestal line feature of 10 fingerprints is only extracted in breath, this 10 crestal line features are matched with preset 8 crestal line features, In, 10 crestal line features and the preset crestal line feature only successful match 4 of extraction, first biology of this 4 successful match Feature is first matching characteristic.4 be first number.Here 4 are less than the first designated value 6, this when is obvious This verification does not pass through.Step S430 will be executed at this time in the present embodiment, record the crestal line feature of this 4 successful match. The reason of leading to such case is, such as electronic equipment has recorded the crestal line feature of 8 fingerprints of user, but this 8 ridges Position of the line feature just with this acquisition finger mutually staggers, this verification is caused not pass through.Certainly it could also be possible that it is illegal Caused by the fingerprint input of user, therefore in the present embodiment on the one hand in order to improve the success rate of verification, on the other hand ensure to test The safety of card will resurvey biological information in step S440 within the first specified time, this first it is specified when Between can be the preset shorter time, such as numerical value such as 5 seconds, 10 seconds or 8 seconds can at least 1 biology of repeated acquisition Feature.And will from the biological information of follow-up repeated acquisition extract third biological characteristic, and by third biological characteristic with Second biological characteristic is matched, determine in third biological characteristic with second biometric matches and with the first matching characteristic Nonoverlapping second matching characteristic.Again by taking fingerprint as an example, when second of fingerprint collecting, with preset second biometric matches The number of biological characteristic is 5.It is Chong Die with the first matching characteristic there are one but, merged by duplicate removal this when, is determined The number of acquisition twice and the biological characteristic of the second biometric matches is 8.Here 8 are second number and first The sum of number.The sum of second number and first number are more than 6 described in this obvious when, then are verified.If described second The sum of number and first number are less than 6, indicate that the sum of second number and first number are less than the first designated value, then it is assumed that verification Do not pass through.

If within the first specified time, by the acquisition and matching of multiple biological information, still verifies and do not pass through, then It can delete recording before with the second biometric matches the first matching characteristics and the second matching characteristic.

It obviously, can be to avoid in the inaccurate caused conjunction of physical characteristics collecting using the verification method described in the present embodiment Method user repeatedly inputs biological characteristic, the phenomenon that still having no idea to pass through verification, improves the intelligent and right of electronic equipment The percent of pass of the verification of validated user.

Specific example one is provided below in conjunction with above-described embodiment one：

Fingerprint recognition is used to carry out fingerprint authentication first.If at this time because the crestal line of the fingerprint of electronic equipment successful match is special Levy number not enough authentication failed, electronic equipment can the crestal line of automatic Memory successful match adjust and preserve certain time.This In crestal line be characterized as one kind of fingerprint characteristic.It is being spaced in the very short time, if carrying out fingerprint authentication again, electronic equipment meeting On the basis of previous, continue to acquire and filter identical fingerprints crestal line feature, as of the crestal line feature of multiple successful match When number reaches pre-set threshold value, fingerprint authentication passes through.Here predetermined threshold value corresponds to the first designated value in previous embodiment.If Fingerprint recognition is unsuccessfully attempted to be more than certain number, then automatically into character unlock interface or pattern unlock interface.

During fingerprint authentication, if the crestal line characteristic of successful match is f, different f are directed to, electronic equipment can be held The different operation of row.

f>=S:The quantity of the crestal line feature of successful match meets the quantity of system requirements, it may be considered that being validated user Operation, subsequently unlock electronic equipment, authorize application etc. permissions；Here S is specified threshold.

0<f<n：The quantity of the crestal line feature of successful match is inadequate, then shows to identify that this may be validated user operation, And the quantity for the crestal line feature of the possibility and successful match of validated user is positively correlated, the number of the crestal line feature of successful match Amount is more, then shows that possibility is bigger, electronic equipment needs secondary acquisition.

F=0：That is the quantity of this crestal line feature for not extracting successful match then shows this user very likely not It is validated user, electronic equipment is not unlocked.Here 0 is equivalent to the second designated value in previous embodiment.

When entering pattern character formula unlock interface, no longer number is limited, but electronic equipment backstage can be done accordingly Record.User carries out (containing disabled user) number of pattern character formula unlock, if being more than certain number, system is automatically into record Pattern.In this mode, user continuously inputs the password of certain number by mistake, then has input correct password, then has input mistake again Password accidentally, electronic equipment can prompt to be once that input is correct in user x time at random, please continuously input x times it is correct close Code, you can unlock (x>=2, x's is secondary related with the number of input error, and wrong number is more, then requires continuous input correct Number is more).Here password is verification information above-mentioned.

This fingerprint recognition mode can greatly promote the success rate of unlocked by fingerprint in this programme, improve user's body It tests, there is certain practical value.For the supplement verification mode after fingerprint recognition failure, the coping mechanism in this programme, both It can ensure the Brute Force that validated user goes to be attempted, and prevent disabled user without any idea by memory, have one Fixed practical value.

Embodiment two：

Step S420：Judge in first biological characteristic with preset the first matching characteristic of second biometric matches Whether first number is less than the first designated value；

The method further includes：

If it is determined that third biological characteristic and second biological characteristic that the biological information acquired from n-th extracts Matching number be less than the second designated value, then delete record before n-th acquisition with second biometric matches Biological characteristic；Wherein, the n is the positive integer no more than the N.

Second designated value described in the present embodiment is less than first designated value；First designated value is just whole Number；Second designated value can be 0 or less than first designated value positive integer.
