Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Generally exist
The component of the embodiment of the present invention described and illustrated in accompanying drawing can be configured to arrange and design with a variety of herein.Cause
This, the detailed description of the embodiments of the invention to providing in the accompanying drawings is not intended to limit claimed invention below
Scope, but it is merely representative of the selected embodiment of the present invention.Based on embodiments of the invention, those skilled in the art are not doing
The every other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
Embodiment 1
Referring to Fig. 1, the identity identifying method based on finger-print cipher provided in the present embodiment, including step：
Obtain the fingerprint sequence of user's typing.Fingerprint sequence includes multiple fingerprints, and multiple fingerprints are in particular order
Arrangement.User can not repeat typing in typing fingerprint sequence, for the fingerprint of same position, such as can not be because of some hand
The fingerprint of finger does not have typing success and repeats the fingerprint of the typing finger, avoids influenceing the judgement whether fingerprint matches.
By the fingerprint of each position in the fingerprint sequence, enter with the fingerprint of correspondence position in the standard fingerprint sequence that prestores
Row compares, and counts the number of fingerprint matching.
In this step, if a certain position does not collect fingerprint in the fingerprint sequence obtained, or the fingerprint and mark collected
The fingerprint of correspondence position is not consistent in quasi- fingerprint sequence, then judges the fingerprint and standard fingerprint of the position in the fingerprint sequence of acquisition
The fingerprint of correspondence position mismatches in sequence.Fingerprint can not be collected, it may be possible to because the fingertip tracking leads to not typing and referred to
Line, it is also possible to the finger injuries and cause the fingerprint of typing very fuzzy and None- identified.The fingerprint and standard fingerprint collected
The fingerprint of correspondence position is not consistent in sequence, it may be possible to which finger part missing causes the fingerprint of typing to be only the one of finger print
Part, or because order misremembers and causes the fingerprint of other fingers of typing.
Judge whether fingerprint matching rate is more than or equal to given threshold, if it is, authentication success, otherwise authentication
Failure.Threshold value is set to bigger, and the security that finger-print cipher uses is higher, and threshold value sets smaller, the spirit that finger-print cipher uses
Activity is bigger, can avoid because various normal reasons cause the fingerprint sequence of user's typing to differ with the standard fingerprint sequence to prestore
The situation of cause.Authentication side can require to carry out different settings according to different.
For example, for the ease of description, the fingerprint of a finger is represented with a numeral herein, such as 1/2/3/4/
5 represent the fingerprint of the left hand thumb/forefinger/middle finger/third finger/little finger of toe respectively, 6/7/8/9/0 represent respectively hand thumb/forefinger/
The fingerprint of the middle finger/third finger/little finger of toe.It is assumed that threshold value is 80%, the standard fingerprint sequence to prestore is 3,4,6,2,1,0,5.
If the fingerprint sequence of user's typing is 3,4,6,2 ,-, 0,5, for the ease of description, represent not adopt with "-" herein
Collect fingerprint, then fingerprint matching rate is 85.71%, authentication success.
If the fingerprint sequence of user's typing is 3, A, 6,2,1,0, A, for the ease of description, represent to gather with alphabetical A herein
To fingerprint be not consistent with the fingerprint of correspondence position in standard fingerprint sequence, then fingerprint matching rate be 71.42%, authentication lose
Lose.
Authentication is carried out by the above method, the security that finger-print cipher uses can be ensured, must also be avoided because of hand
Refer to the normal reason such as injury and cause the fingerprint sequence of typing and standard fingerprint sequence not quite identical, and then cause finger-print cipher
It is unable to the situation of normal use.
Embodiment 2
Referring to Fig. 2, the identity identifying method based on finger-print cipher provided in the present embodiment, including step：
Obtain the fingerprint sequence of user's typing.
By the fingerprint of each position in the fingerprint sequence, enter with the fingerprint of correspondence position in the standard fingerprint sequence that prestores
Row compares, and counts the number of fingerprint matching.
Judge whether fingerprint matching rate is more than or equal to given threshold, if it is, authentication success, if fingerprint matching
Rate is less than given threshold, then determines whether in standard fingerprint sequence, and whether the fingerprint for mismatching position is same fingerprint, if
It is then authentication success, otherwise authentication fails.
Illustrate, it is assumed that threshold value 80%, the standard fingerprint sequence to prestore are 3,4,6,2,1,2,5.If user because
Cause the part missing of left index finger for certain reason, then the fingerprint sequence of user's typing would is that 3,4,6, A, 1, A, 5, lead to
Cross with standard fingerprint sequence alignment, matching rate 71.42%, but mismatch position fingerprint be to come from left index finger, this
When then judge authentication success.
If the fingerprint sequence of user's typing is 3,4,6, A, 1,2, A, by being with standard fingerprint sequence alignment, matching rate
71.42%, but in standard fingerprint sequence, respectively from left index finger and left hand little finger of toe, i.e., the fingerprint for mismatching position is
Respectively from different fingers, now then think to may not be user's operation, potential safety hazard be present, therefore judge authentication
Failure.
In finger-print cipher, the fingerprint that same finger be present is used multiple times, can by the present embodiment method
To avoid the fingerprint because of some finger from not gathering correctly, and in the case that the fingerprint of the finger is used multiple times, cause fingerprint
Password can not be proper use of situation.
Usually, based on security consideration, when setting finger-print cipher, user generally will not be by the fingerprint of same finger
Reuse too much, such as in a standard fingerprint sequence, there are 7 fingerprints, wherein 4 and above fingerprint come from same hand
Refer to, therefore, if fingerprint matching rate too it is low may if be not because normal reason causes the fingerprint sequence of typing and standard fingerprint sequence
The outer not quite identical situation of row, and more likely it is not user's operation.Therefore in order to improve security, as shown in figure 3, on
If stating fingerprint matching rate is less than given threshold, determine whether in standard fingerprint sequence, mismatch position fingerprint whether
For same fingerprint, if then authentication success, otherwise the step of authentication failure, is replaced by following steps：
If fingerprint matching rate is less than given threshold, and is more than or equal to lower threshold, then standard fingerprint sequence is determined whether
In row, whether the fingerprint for mismatching position is same fingerprint, if then authentication success, otherwise authentication fails.
Still using above-mentioned for example, set lower threshold as 60%, if the fingerprint sequence of user's typing is 3,4,6, A,
1 ,-, A, by with standard fingerprint sequence alignment, matching rate 57.14%, but be less than lower threshold, now then judge identity
Authentification failure.
Referring to Fig. 4, provide a kind of identification authentication system based on finger-print cipher, including fingerprint simultaneously in the present embodiment
Retrieval module, fingerprint comparison module, and authentication module.Wherein,
Fingerprint sequence acquisition module is used for the fingerprint sequence for obtaining user's typing；
Fingerprint comparison module is used for the fingerprint of each position in the fingerprint sequence, and in the standard fingerprint sequence that prestores
The fingerprint of correspondence position is compared, and provides the result whether matched.Fingerprint comparison module is when comparing, if the fingerprint obtained
A certain position does not collect fingerprint in sequence, or the fingerprint not phase of the fingerprint collected and correspondence position in standard fingerprint sequence
Symbol, then judge that the fingerprint of the fingerprint of the position and correspondence position in standard fingerprint sequence in the fingerprint sequence of acquisition mismatches.
Authentication module is used for the number for counting fingerprint matching, if fingerprint matching rate is more than or equal to given threshold, identity is recognized
Demonstrate,prove successfully, otherwise authentication fails.
In another embodiment, authentication module is used to count the number of fingerprint matching, if fingerprint matching rate is more than etc.
In given threshold, then authentication success；If fingerprint matching rate is less than given threshold, determine whether to mismatch the finger of position
Whether line is same fingerprint, if then authentication success, otherwise authentication fails.
