To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
The present invention realizes the lasting authentication method based on biological characteristic by following computer, as shown in Figure 1, computer packet
Include: host (not shown), the display being connect with host and mouse, setting facial collector 20 over the display and
Fingerprint capturer 10 on mouse is set.Since the utilization rate of mouse is higher, in general, user is when using calculator, mostly
It is held by mouse in the number time, except of course that when both hands are typewrited.That is, when fingerprint capturer 10 does not acquire
Fingerprint or when collecting the fingerprint of other people, it is possible to divulge a secret.Certainly, it when both hands are typewrited, is adopted by face
Storage 20 distinguishes user, and facial collector 20 also can be set in other positions, as long as convenient for the facial information of acquisition user
, for example, using camera in the present invention.
As shown in Figures 2 and 3, the lasting authentication method based on biological characteristic that the present invention provides a kind of, including walk as follows
It is rapid:
Step S10, the finger print information of user is acquired by fingerprint capturer 10 and saves as effective finger print information, pass through face
Portion's collector 20 acquires the facial information of user and saves as effective facial information.
Before the use it needs to be determined that the user of this computer can be used, certainly, user can be several.Then,
The finger print information and facial information of each user of typing saves and completes to register.The finger print information and facial information group of each user
At the biological characteristic group of user, can also be verified using other biological characteristics of user.Here finger print information, usually
The fingerprint of user's right hand, more specifically, fingerprint capturer 10 is located at the left side of mouse, for acquiring the hand thumb of user.When
So, other positions can also be set, the fingerprint of corresponding finger is acquired.
When acquiring finger print information, fingerprint capturer 10 is used to carry out the acquisition and typing of fingerprint, has been clicked in main interface
" saving fingerprint " can carry out the preservation of finger print information, " clicking to match " be clicked, by existing input finger print information and fingerprint base
Middle fingerprint is compared, and returns to matching result.
Step S100, every the first preset time, the finger print information of user is acquired by the fingerprint capturer 10 on mouse.
After user starts computer, password login can be used or fingerprint authentication logs in.Specifically, by fingerprint authentication
Program embedded system, so that user can be used fingerprint authentication and log in, to greatly improve user experience.Meanwhile system
Retain the original password login mode of Windows, user is allowed to pass through password login to computer.Log into thr computer into
When row fingerprint authentication, may determine that it is which user by the fingerprint that fingerprint capturer 10 acquires, therefore, the use can be recalled
The biological characteristic group at family, i.e. finger print information and facial information, so as to lasting certification.
After user's log into thr computer, in using computer procedures, by fingerprint capturer 10 every the first preset time
The finger print information of a user is acquired, i.e. it not is that only verifying is primary that fingerprint collecting, which is to continue to carry out,.In the finger of verifying user
When line information, due to when logging in, that is, the biological characteristic group of the user having been recalled, first in the user during subsequent authentication
Biological characteristic group in matching, without being matched in fingerprint base, convenient for improve matching efficiency.
Step S200, when not collecting the finger print information of user, every the second preset time, pass through facial collector
20 acquisition user's face information.
For user during using computer, the right hand may be detached from mouse, such as in both hands typewriting, this when standby
Family is still using computer, cannot lock computer.The hand of user is detached from mouse, and fingerprint capturer 10 does not collect user
Finger print information, then start the facial information that facial collector 20 acquires user.Certainly, user is when using computer, can be with
Third preset time is set, when the finger print information of acquisition is effective fingerprint and continues third preset time, starts face acquisition
The facial information of the acquisition user of device 20.Prevent the person of stealing secret information from copying finger print information, so that fingerprint capturer 10 takes for the finger of acquisition
Line is effective fingerprint.It is larger that facial information copys difficulty, and is easy to be found, therefore, further true by facial collector 20
Recognize the user using computer.
The step S200 is specifically included:
Step S210, when the finger print information of acquisition is effective finger print information, judge whether computer is in the lock state.
User has the case where leaving computer and reusing in using computer procedures, and (certainly, user leaves meter
After calculation machine, needed for secrecy, computer locks automatically), alternatively, user is before using computer, computer is had been started up
And logged in by other users, but computer is now into lock state.In the present invention, though computer into lock state,
Still when the finger print information of continuous collecting user, only computer are closed, just stop the finger print information of acquisition user.
Step S220, when computer lock timing, the finger print information of user is unlocked and continues to acquire, when computer does not have
When locking, judge whether the finger print information of user changes.
If user leaves after having used computer, computer enters lock state, has other people to use meter again later
It when calculation machine, also needs to log in and unlock, certainly, user can be unlocked by password, can also pass through fingerprint capturer
10 unlocks.After user's hand-held mouse, fingerprint capturer 10 acquires the finger print information of user, if the fingerprint of acquisition is effective fingerprint
Information, computer is in the lock state at this time certainly, then computer unlocks.
If the finger print information of acquisition is effective finger print information, and computer is not on lock state, then needs to judge
Whether the finger print information of user changes, because when user uses computer, it may be possible to and multiple users are used alternatingly, although he
Finger print information be all effective finger print information, but due to matching finger print information when, carry out first a user biology spy
Sign group is matched, once user is replaced, then the biological characteristic group of original subscriber and new user are different, then acquires fingerprint or face
When portion's information, need to further it matched in fingerprint base or facial library.
Step S230, it when the variation of the finger print information of user, switches to new user and continues to acquire the finger print information of user.
In order to ensure matching efficiency, if the finger print information of user changes, that is, the user's replacement occurred, then by protozoa spy
Sign group replaces with the neoformation feature group of new user, namely is switched to new user, in fingerprint collecting process next time, calls new
Biological characteristic group.
Step S300, when the finger print information of acquisition is invalid finger print information or the face for not collecting facial information or acquisition
When portion's information is invalid facial information, computer is locked.
When the finger print information of acquisition is invalid finger print information, i.e. the user does not have permission to use computer, it may be possible to steal
Close person, computer can lock automatically.
When not collecting facial information, illustrate that user has left computer, then computer locks automatically, prevents other
There is no the people (including the person of stealing secret information) of permission then to use.
When the facial information of acquisition is invalid facial information, equally, which does not have permission to use computer, it is possible to
It is the person of stealing secret information, computer can lock automatically.
The step S300 is specifically included:
Step S310, when the facial information of acquisition is effective finger print information, judge whether the facial information of user changes.
Step S320, when the facial information of user does not change, continue the facial information for acquiring user, and continue to acquire
The finger print information of user.
Step S330, it when the variation of the facial information of user, switches to new user and continues to acquire the facial information of user,
And continue to acquire the finger print information of user.
As finger print information, when acquiring facial information, it is also possible to the case where user's replacement occur, it is therefore desirable to sentence
Whether the facial information of disconnected user changes.
If the facial information of user does not change, that is, it is still the same user, then continues the face letter for acquiring user
Breath.If the facial information of user changes, that is, there is user's replacement, then switch to new user and continues to acquire user's
Facial information, then user when matching facial information, can call neoformation feature group to be matched first, if mismatch
It is further matched in facial library again.
Since the facial information acquisition difficulty and difficulty of matching of user are larger, and the acquisition difficulty of finger print information and matching are difficult
Degree is smaller, and the hand of user is detached from mouse, can turn again to using mouse.Continue acquire user facial information while also after
The finger print information of continuous acquisition user.
Step S340, when the finger print information of acquisition be effective finger print information when, stop acquisition user facial information and after
The finger print information of continuous acquisition user.
When the finger print information of acquisition is effective finger print information, show that the hand of user returns on mouse again, then it can be with
Stop the facial information of acquisition user, and continue the acquisition of finger print information, realizes lasting certification.
Step S400, when computer lock timing, the finger print information of user is acquired, when the finger print information of user is invalid fingerprint
When information, starting alarm device is sounded an alarm.
Computer further include: the alarm being connect with host.If the person of stealing secret information matches not in finger print information or facial information
After successfully leading to computer locking, continue to attempt to steal secret information, such as, continue to hold mouse being operated, due to computer
Finger print information is still acquired in locking, certainly at this point, the finger print information for the person of stealing secret information remains as invalid finger print information, then starts police
Report device sounds an alarm or shuts down computer.
It is worth noting that the computer locking in the application operates, it also could alternatively be computer and nullify operation.This hair
Fingerprint matching and facial match in bright sets matching threshold, when characteristic point changing value is less than by the way of Feature Points Matching
When matching threshold, it is believed that successful match；When characteristic point changing value is greater than matching threshold, it is believed that it fails to match.
Compared with existing best technique, the present invention has the advantages that
1. the present invention realizes based on finger print identifying, finger print identifying and face authenticating in conjunction with inclusive authentication mode come into
The lasting certification of row, the problem of improving the safety deficiency for relying only on face authenticating and be not available under dark condition.
