Abstract
The invention discloses a quick fingerprint comparison method and device used for a fingerprint lock. The invention can realize quick unlocking of a host, optimize average unlocking rate of guests, avoids erasion of host storage zone in frequency use and prolong use time of a storage as much as possible. The method is characterized in that fingerprint features of the host and the guests are stored separately and host library comparison is performed in sequence at first. If host library comparison is performed and matching success is indicated, a matching result is returned immediately and guest library comparison is saved. If host library comparison is performed and matching failure is indicated, guest library comparison is performed in sequence. During the whole process, host fingerprint feature storage sequence is not in dynamic adjustment. In guest library comparison, if matching success is indicated, the guest fingerprint feature rolls forward to the top of the guest library. Namely, storage according to a dynamic sequence of the last time use is made.
Description
Technical field
The present invention relates to Fingerprint Lock technical field, and in particular to a kind of quick fingerprint comparison method and dress for Fingerprint Lock
Put.
Background technology
Generally in the practical application of Fingerprint Lock, when memorizer is stored, can carry out to each fingerprint characteristic in order
Numbering, and whether the labelling fingerprint is owner, conventional storage mode can be found in table 1 below.
Table 1 represents traditional Fingerprint Lock memory storage mode
Fingerprint ID represents the sequence number of fingerprint in table, leads to commonly used digital expression, such as：No. 001 to No. 100.Due to fingerprint it is usual
It is to be obtained with the mode of pressing, deformation of the difference in pressing position and direction, the situation of finger and skin etc. all can cause
Fingerprint image is undesirable.Therefore, the fingerprint grayscale image for collecting should not be used directly to matching, need to use image processing method
The array (fingerprint characteristic i.e. in table, also referred to as fingerprint template) being made up of series of features value is converted it into, then is used
In fingerprint matching.
In order to improve the stand-by time of Fingerprint Lock, fingerprint comparison computing chip power consumption is relatively low, and calculating performance is weaker, works as user
During using Fingerprint Lock, Fingerprint Lock one by one will be compared the fingerprint for collecting with the fingerprint in storehouse.If fingerprint to be checked
Storehouse is large number of, and the time that complete query is one time is longer, and comparing one piece of fingerprint needs 20-50 milliseconds.Occurring in that now various has
The technology of Fingerprint Lock, such as a kind of existing intelligent access control system and its control method are closed, using fingerprint and finger venous information ratio
To method access control, every time, after checking, memorizer will be substituted the method with current freshly harvested biological information
The biological information of initial typing.If authentication failed, by biological information storage to ephemeral data area, same bio information
Multiple authentication fails, and will be stored by alarm module and be reported to the police.The method and terminal of another unlocked by fingerprint, in fingerprint ratio
Pair when, matched with the finger print information for collecting by the clooating sequence of the fingerprint template for prestoring, wherein, in the fingerprint template
One matching fraction of each fingerprint template correspondence, and clooating sequence is to match fraction order from high to low；Matching target
During matching value, terminal is unlocked, wherein, object matching value is first matching between finger print information in fingerprint template
Fingerprint template corresponding matching value of the value more than the first predetermined threshold value.Can be by the higher fingerprint template row of matching fraction by terminal
Above matched with finger print information, thus improved matching efficiency.The method and terminal of also a kind of unlocked by fingerprint, in fingerprint
When lock is compared, the display page for unlocking application is waited described in parallel refreshing；The finger print information and the preset fingerprint information into
When work(is matched, show the display page after unblock application is refreshed.Because fingerprint matching shows the page with refreshing
Process synchronously carry out, thus, can shorten for wait unlock application unblock time, improve unblock efficiency.
Above technology is compared using traversal whole fingerprint characteristic storehouse mode, and owner is special with guest (including nurse etc.) fingerprint
Mixing storage is levied, comparison efficiency is low.In addition to the method and terminal of unlocked by fingerprint, the storage order of fingerprint is not adjusted,
Commonly used user may come occasionally use and compare behind user, cause comparison time to waste.
Above-mentioned intelligent access control system and its control method replace fingerprint base information after success is compared every time with new fingerprint,
Although may improve that effect is compared next time, the erasable service life for reducing storage device repeatedly, and and be not optimised
Compare speed；Simultaneously as sensor surface pollution, the pressing reason such as posture is nonstandard, freshly harvested fingerprint clear degree may
Without the fingerprint image high definition gathered during initial registration, after being likely to result in new collection image replacement fingerprint base image every time
It is continuous to compare.
The all fingerprints of method and terminal-pair of above-mentioned unlocked by fingerprint adjust the storage location in memorizer every time, although excellent
Comparison time, but the erasable service life for reducing storage device of high frequency are changed.
The method and terminal of above-mentioned unlocked by fingerprint simply shows fingerprint comparison meeting, fingerprint comparison is calculated has been carried out parallel
