Technical field

The invention mainly relates to a kind of finger guide for being referred to as finger guide device, in scanner or sensor or The finger containing specific details, thumb are positioned on other devices or refers to portion to catch the main and relevant part of the details The image of tiny characteristic, it is also equivalently referred to as fingerprint.This finger guide device can be used for electronics, optics, electroluminescent hair Optical, electromagnetic, capacitive character, based on pressure or similar scanner or sensor, they require repeatedly and appropriate accurately will Finger is positioned to be directed at scanner or sensor, and sensor or scanner are placed in contact pilotage or pen.Its application includes accurate Discriminating or identification is personal or specific finger of individual so that by False Rejects or for scanning, sensing or catch fingerprint About and preceding registration part process repetition number it is minimum.

Background technology

U.S. Patent application No.2004101172（Lane）Disclose a kind of finger imaging system of finger for recipient System, its fingerprint is obtained using automatic fingerprint reader.The system includes the finger for having for receiving the finger for being acquired fingerprint The finger imaging device of receiving portion.Locating rod stretches out from finger receiving surface, in finger is approximately in ideal position When, it engages the wrinkle of skin of subject finger.U.S. Patent application 2004101171（Lane etc.）Disclose a kind of for receiving With the finger imaging system of the finger for keeping people, its fingerprint is obtained using automatic fingerprint reader.The system includes thering is finger The finger imaging device of receiving portion and finger position portion, the part forms the recess for reducing size so as to be forced together The subject finger being inserted to property is maintained in settling position.And last, U.S. Patent application No.2004076314 （Cheng）A kind of equipment is disclosed, it includes fingerprint sensor and guide.The sensing position of fingerprint sensor fills with guiding The guide plane put forms relative and obtuse-angulate angle.

Traditionally, in order to record fingerprint, by ink be coated to finger and then finger by " rollings " pass through paper or Other ink receptive surfaces are printing fingerprint image.By contact surface and the fingerprint that leaves Residual oil and leave by various technologies Catch, their " lifting " and disclose fingerprint.

In recent years, alternative technology is proposed, they can disclose the tiny characteristics in fingerprint and directly from finger Or fingerprint is caught with the biological tissue below the finger skin surface for forming finger minutiae to outgrowth.Electronic transducer technology Including when system by finger areas or only finger areas a part detection skin or histological difference so as to disclose fingerprint Image is illustrated to form the electronics of fingerprint, such as when as digital document, finger is kept on sensor-based system.The example Including optical scanner, electro-luminescent pressure sensor-based system, the integrated circuit of the electric capacity that can measure each pixel size etc..

The production cost of some type of fingerprint scanning systems is subject to promoting by the size in sensing finger region.For silicon Base or integrated circuit（IC）Type sensor is particularly so.Such as most of IC, IC is bigger, if device geometry and the number of plies Equal, then its production cost is higher.The production cost of sensor is directly relevant with sensing area, and sensor is extensive Production, when the relevant part of only finger needs to be scanned to set up fingerprint identification system, thumbnail size is not optimal.Such as Fruit using only the relevant part of fingerprint to reduce system cost, then importantly, for every time differentiate or identification events, will with The relevant part of the finger of first registers is almost identical to be partially disposed on sensor.

Obvious less sensor cost is lower, and assume by the relevant region of sensing finger be still necessary to it is sufficiently large with Acceptable matching capacity or safe class are provided, then preferred plan will be this less sensor, not consider most Whole finger-print region.Finger guide device of the invention is such a device, and it can be used for reliably on small sensor Finger is repositioned to carry out identification effectively.The device reduces due to finger not being positioned to be sufficiently close together False Rejects caused by one or more positions of its initial registration.The finger guide device ensures that sensor can read and refers to The relevant part of line matching, it is used to ensure to read those for catching and storing with for the template for comparing and matching substantially The relevant part of identical.When every time using fingerprint recognition system, the finger guide device is by naturally（For example, cosily Or intuitively）Non-mandatorily subject finger is directed to substantially（Substantially）Reduced at identical and initial registered location The generation of False Rejects.

When smaller sensors are used, if registering finger in such a manner, that is, a relevant part of finger is scanned, Or may finger printing area multiple laps, then they be electronically assembled into by computer and represent initial subject and refer to One complete " template " of the bigger part in part that any independent scanning of ratio of line can be produced alone, then the system rely on In subject user can as one man feeler be passed so as to the relevant part of matching of finger in identical approximate location Sensor reads and thus allows for accurate discriminating.Not reapposing finger accurately in essentially identical position causes mistake Refusal；, or in other words, because sensor sees the different and irrelevant region of finger, then it can not be from a template The relevant fingerprint portion matched data in preceding registration, and it refuse it is known can received subject user.This is a kind of False Rejects.If system its other trial, and if second or subsequent trial final alignment contain matching and exist The details of the fingerprint about part of part is initially stored during registration, then the main body is received（Identified or " discriminating "）.Pass through There is provided simple for one kind of finger, basic oval or rectangular in shape funnel-form guiding piece, the guiding piece actually promotes finger to enter In entering correct position, and for subject user provides various haptic feedback devices so that it " finds " just more easily again True position, even if passing by between registration and next discriminating event for a long time, the finger guide device is reduced and is used for Differentiate the average time of the trial of known main body.Conversely, being enclosed using basic flat surface sensors or by substantially flat surface Around sensor or the even sensor of poor design, for the main body not being trained to, the model of this false rejection rate Enclose 10 to ten five from all trials, or the even more high for different system setting.

The content of the invention

Substantially round, avette, square or rectangular funnel guiding fluid is very similar to enter in container；Finger guiding dress Put or finger " pit "（Recess）For guiding finger towards same position on a sensor in a repeatable fashion.Another letter Single analogy is to describe the ball in cone apex, with the ball phase being seated at the global minimum of reverse taper or recess Than it is unstable, and wherein ball is rolled to identical global minimum position always by Action of Gravity Field and recess sidewalls. In the situation of finger guide device, so not obvious effect is started by muscle, so as to apply appropriate active force to hold Change places and slide finger towards sensor region, by the communication with subject user and the proper motion towards the position, this Plant and move described in finger guide device and disclosed physics, material and tactile element guiding with each time by hand Finger is directed to touch feedback reality from the side wall that in ergonomics mode designs of the same position also by the device The existing proper motion.The sensor will be seated in finger guiding in neighbouring correct position of the preferable finger about region So as to the preferred part of " seeing " fingerprint in window at bottom of device（It is raised）.

Focus on keeping on finger to carry out the former device of fingerprint imaging for positioning finger（Almost extrude）To flat Requirement on scanning of a surface and the skin wrinkle below the first joint for tending to roughly from nail leading edge or in finger Line positions finger.This intention seems to substitute the effect of rolling fingerprint and seems to turn into a weight for flattening the pressure of finger Want element.Modern semiconductors or sensor require nothing more than contact gently, and as observed by, often focus on constantly repeating to sweep The essentially identical relevant position of fingerprint is retouched or catches, as long as finger keeps substantially active alignment sensor.The present invention is provided A kind of effective auxiliary and a kind of learning organization, it contributes to main body that finger is positioned at into correct position on the basis of repeatable In putting, and finger relevant part alignment scanner or sensor, and also by including physical form, feedback device and material One group of approach of characteristic forms correct contact（Pressure）.Additionally, the device is designed to non-mandatorily reposition fingerprint region Domain, the distance on the downside of the region to nail substantially between 0.20 and 0.90 inch, and therefore, from the finger from below nail Convex ridge below point positioning rather than the first joint in finger.Additionally, the finger guide device ridge tool at front portion There is sufficiently low profile to avoid contact with nail.This contact is introduced into error, because different subjects are sometimes in the different time It is different length by its Nail clipper, and it is most of it will also be appreciated that the pressure acted in nail tip is uncomfortable, and this two The situation of kind is present in former device to position finger on fingerprint reader or scanner.

The physical Design of finger guide device makes it possible to precisely enough by finger about being partially disposed in sensor To significantly improve receiving for the first time on center（It is registered main body）Percentage.This is included at finger guide device front portion The short concave radius of comparing（Or the slope of steeper）, herein, finger tip contacts or close just below nail The front portion of finger guide device；And the radius concave shape more long of proximity sensor opposite side（Or without so precipitous Slope）, herein, cup extends towards human body along finger.Side on the either side of scanner or sensor region is very In determining on scanner or sensor the precipitous relevant parts transversely to keep finger.Generally, the finger guide device Size is suitable to general finger, but is adapted to wide range of finger size because it only contact finger or refer to it is less Relevant part.

What is allowed for finger is placed on installation less electronic sensor on flat surfaces allows Degree is quite tolerant, however positioned on these devices without the finger guide device benefit the relevant part of finger for without It is difficult for the main body of training.This may be limited to the substantially half of finger-print region that will be scanned to three/it is double About part, this depends on algorithm and system accuracies used to other of scanning and the fingerprint that is present in template before being stacked in. Low accuracy systems can be operated so that being set lower than the sensor window of half in differential scanning and its in by storage template Crossover between corresponding relevant part.Actual relevant for secure match requirement partly depends on algorithm, and in algorithm In, actually required safe class or security setting.This and the scanned main body that template is associated that is registered with the main body Fingerprint relevant part it is related.

It is consistent with it is repeatable on the basis of by the identical of fingerprint about being partially installed in the effective coverage of sensor （Window）On ability be easy to quickly and precisely first attempt matching and this significantly reduces false rejection rate.It is being registered But unskilled main body in, False Rejects are reduced to 10 by the finger guide device invention.Drawn using the finger The practice for leading device or system optimization or combination of the two will further decrease false rejection rate；And using optimised In the ideal case of system, false rejection rate can be fallen below percent by the finger guide device in contact pilotage or pen Two.

Refused from the mistake in the range of 10% and 20% for attempting and with about 15% to the average value less than 2% The reduction of exhausted rate is significant in terms of the security system based on pen or contact pilotage receives with market acceptance.Subject user Sense of frustration in crowd is significantly reduced, if people without multiple-contact sensor so as to being received.This is in pen or contact pilotage It is especially important in, wherein generally needing specific user's dexterity to be carried with for discriminating trial other each time Play and change finger.As aiding in and being easy to this device practical operation being required to the special dexterity demands of reduction, Some pens for being equipped with fingerprint include special pliable clamping or non slip grip surfaces.

At year ends 2003, a kind of new keyboard is introduced to substantially 250,000 user and without finger guiding Device scheme.The company that there is sizable setback in user library and dispose the system faces severe criticism.This problem So that user queries the service behaviour of system, even if the problem is considered as technically user's no essence in discrimination process True placement finger（Misalignment sensor）Mistake or user error.Finger guide device reduces this expected user Mistake and improve first time contact in the received possibility of main body.This has saved the plenty of time on lifetime of system And be the key element for developing biometry system, in terms of user time and efficiency it can as one man with password or PIN is compared.

In practical operation and application, registered using finger guide device and discriminating is improve finger guide device Effect.Because the natural feeling of finger guide device directed the user to each time in ergonomics mode it is roughly the same Position or the relevant part of finger is aligned on effective sensitive zones.This bootup process is physics and neutral, Used hence for first time and provide touch feedback with for subsequent study.

During registering, system may in multiple times require main body movement finger and make finger contact scanning device or sensor （For example, " lifting and replacing " finger）.Finger guide device is generally designed to accommodate the hand of left side or right side limbs Refer to or thumb.This shows that it contributes to this multiple placement but this placement strictly is not limited into accurate and essence The accurate placement for really repeating, it only causes this being placed in the permissible range of sensor and algorithm so as to subject finger Relevant part alignment scanner or sensor.This allows template to exceed preferable or " suitable " window frame（It is raised）Strict limit Make and therefore form buffer zone, it is designed in the range of permission adapt in following appropriate misalignment grade And the guidance capability of finger guide device.For long-term, for repeatable energy, this function is important, and by The alignment ability that finger guide device promotes only needs to be increased to the limit required by matching system, including but not limited to template size With the safe class of algorithm.

Some sensors drive current potential or electromagnetic signal to enter in finger tissue.This can be radio frequency signals.Hand Finger guide or its surface can be conductive so as to be easy to this application during registration and subsequent discriminating event.Finger Guide may be designed to have the preferred embodiment of basic parabolic shape will reflect with during being referred to as illuminating Electromagnetic energy is focused on the relevant part of finger and improved by the feature of heat transfer agent.

The surface characteristic and material for being selected for finger guide device are important for performance.Because finger should This is easy to slide in place, low-friction coefficient（Slide coefficient and static coefficient）For allowing finger to be still in its natural overall situation most It is useful at small value position, the position is located at the bottom of the finger guide device of appropriate positioning on scanner or sensor At portion.Constantly be positioned at finger in identical close position by the surface characteristic and outcome procedure.With appropriate low friction system Several example of material include but is not limited to smooth metal, smooth plastics are even painted, polishing or waxing surface.Such as Fruit surfacing has coefficient of friction high, such as rubber, polyurethane-based material or rough plastic, the effectiveness of finger guide device Can be lowered or damage with function.Moistening or dry lubricant and cured it also is coated with and appropriate lubricant or even can quilt It is mixed into clean solution or special cloths for cleaning.

Other feedback devices can be included in of the invention preferred or even alternative embodiment.When they are used Finger guide device through lasting, people are by the ability of sensigenous to correct position.The finger guide device can be by having The material of pyroconductivity high is made to provide touch feedback and accelerate this learning process.Example includes but is not limited to gold Category, some ceramics or some carbon-based materials.In this case, finger guide device will make us in the contact of room temperature Feel colder（Relative to pen or the other parts of contact pilotage）, this is not due to its absolute temperature, and because it has works as When being touched, the pyroconductivity that heat is quickly gone out from skin conductance, therefore the quick sensitive table for cooling down finger in contact Face.If finger guide device is made of metal, the characteristic will make it feel like metal contact（Such as cold sensation）.Pass through Compared with silicon sensor and its face coat, feel colder than the remainder of pen, main body is by cognitive finger guide device Correctly " feel " and also will preferably sensory transducers.

Other protuberance can be added to help orientation finger or cause main body " accurate adjustment " their finger position.These It is probably unnecessary for normal or average-size finger, but the main body has the hand of contact very little wherein It is valuable in the application of the very small finger that apparatus surface region is led in guide.

Braille dots can be added to finger guide device in order to blind person or user visually impaired.

The finger guide device also can be used physical component and material property to prevent inaccurate use.For example, implementing A preferred method of the present invention is using harder and unique convex ridge around the finger guide device.Not it is perceived by danger " sharp " object of danger, this convex ridge is used to enable that subject user does not feel well.When a finger is placed across this ridge, Although harmless, it is uncomfortable, because it applies pressure per square inch high on narrower convex ridge line to skin （PSI）.This pressure per square inch high shows that pen is not held correctly in sensing contact.The sense of non-aligned clamping Feel is unnatural sensation and user will by the light of nature to reposition his or her grasping more naturally and comfortable to obtain Sensation.Naturally tendency is to avoid clamping pen in the outer ridge of finger guide in one's hands, but by finger or thumb Slide down in finger guide device and slide into sensor（Desired position）On.Exactly in the correct position, for For subject user, keep contact pilotage feels it is natural and safe（Stabilization）.Sometimes be used interchangeably and conduct The contact pilotage of the equivalent form of value or the wording of pen, herein, for including any elongated instrument, it to be kept or clamped simultaneously by user And can write on the surface.

Further embodiment of the present invention may include active feedback mechanisms, including be designed to for being properly positioned its finger Remind（And training）Main body or be designed to remind main body they received in systems（I.e. their fingerprint is swept Retouch, contrast and correctly match）The fact feedback.Sound can be used for " guiding " finger and reach sensor.Also can be used visual Indicator.Finally, physical motion for example vibrates can remind driver's stall warning to be very similar to when driving an airplane The mode of rod type electromagnetic shaker and used.In another preferred embodiment of finger guide device, with feedback " ticktack " Pressure-responsive motion is used as tactile（And the sound）Feedback signal is with when finger is in guiding piece and applies connecing for proper range User is informed during touch pressure.

The mistake that these feedback mechanisms may be alternatively used for correction system is used.For example, limiting pressure on a sensor or Person lacks contact and can cause scanning problem.Sometimes subject user may feel disappointed because of false rejection rate, may not be just Really show that finger pressure higher will cause the conclusion of system more good berth.Excess pressure can flatten details and cause to pass Sensor saturation and prevent it from accurately resolve minutiae.May be such that details not conversely, form is the kick the beam absence of pressure of contact Can be differentiated by sensor and good image can not be produced.In any case, voice command or sound or art technology Other feedback devices known to personnel can be used for transmitting needs the requirement to loosen clamping or even more strongly extrude.Language Sound or sound or other feedback devices can be passed on to main body and need to mitigate contact or somewhat lift finger.It is another feasible Scheme is that sensor is slightly moved up and down in finger guide device sensor window, or adjusts manually or use feedback Control loop and actuator system are automatically adjusted, this device be those skilled in the art in electro-mechanical feedback control system field Know.

It is assembling sensor and finger guide device to implement a preferred method of the present invention, and they are designed to as one Individual unit works together, i.e., one system.This requires structure sensor to operate on circuit boards, and the circuit board similarly contains The other support circuit applied for it.Finger guide device, sensor, seal washer and the printing with erecting device connect The combination of line plate may be mounted to that in the shell of contact pilotage or pen.Therefore, the sub-component can for its apply and be placed in it is various not In the contact pilotage or pen housings of same type.

Finger guide device of the present invention and the system for author's fingerprint matching can combine other biometric match sides Method is providing safer whole result.Example includes but is not limited to face recognition, fingerprint in addition, iris recognition, or Retina scanning.In another example, Signature Verification or " DSV " are actually providing signature（Signature）Period catches and numeral Change multiple static and dynamic signature elements and with statistical way analyze the parameters index of these elements with to profit Used in the former signed data for providing（Signature template or even one group identified signature template）What is compiled is identified Storage supplemental characteristic mutually compares.By the signature that he provides, matching can cause to differentiate or recognize the main body.People in the art The known various methods of member recognize that an example of this method is in United States Patent (USP) 5,559,895 to perform this dynamic signature （Lee etc.）In be given and claim, its entitled " for adaptation method and system of real-time authentication dynamic signature ", its Middle form is the measurement of " personalized features " of static and dynamic measurement by " accurate to provide compared with the signature character of registration Signature recognition ".And the patent and prior art are combined here by reference.

Also producing may confirm that known signature person actually has been provided for its signature rather than alternative from remote location Nonideal wording such as sentence, the need for " me oppose " or " I disagrees ".In 2002, Corporate Fraud and responsibility method Case, also referred to as Sarbanes-Oxley laws, include required by a kind of requirement, i.e. some of public body official guarantee Financial statements filings；Also it is possible to group requires the support certification of the key managers in remote operating locations.This text Shelves are generally with strict deadlines and therefore need to complete the ability of support electronic signature process.What internet was promoted is easy to a lot Same eager motivation is provided the need for the remote business of other forms, that is, requires that a kind of certification has been provided for actually legal Valid signature method, including U.S. law perform " it is required that federal agency is using and using digital signature and in individual Encourage to use digital signature in electronic transaction ", the law is referred to as USeSignBill, passes through in October, 2000, and it supports electronics Or the validity of " numeral " signature.This person writing can not be prevented using paperless system, fingerprint sensing pen system itself " I withholds one's signature " or some other sentences and non-express he agree to therefore represent the signature of his wish.Detect this exception The signature of each offer of manual review will be provided（And may even compare " signature card " of submission）, this is also easy to produce people Work mistake or fault.Correspondingly, another preferred embodiment of finger guide device of the present invention is by fingerprint verification and identification System actually endorsed the dynamic signature verification system of effective version of his signature with the main body for confirming to be authenticated It is combined.
