Definitions

  • the system includes a finger imaging device having a finger receiving portion and a finger positioning portion, together forming a recess of reducing dimension such that a subject finger forcibly inserted into it is held in a stable position.
  • U.S. Patent Application No. US2004076314 (Cheng) discloses an apparatus that includes a fingerprint sensor and a guiding means. The sensing site of the fingerprint sensor makes a relative and obtuse angle with a guiding plane of the guiding means.
  • the finger guide device invention is a device which may be used to reliably reposition a finger upon a small sensor to enable more efficient identification.
  • the device reduces false rejects caused by failure to position the finger close enough to its original enrollment position or positions so that the sensor can read a matching relevant portion of the fingerprint.
  • the finger guide device reduces the incidence of false rejects by naturally, intuitively, and non-forcibly guiding the subject finger to approximately the same and original enrollment position each time the fingerprint identification system is used.
  • the finger guide reduces the average number of attempts to authenticate known subjects by providing a simple, funnel like or inverted pyramid like guide for the finger that physically but non-forcibly encourages the finger into the correct position so that a relevant portion of the finger is in alignment with the sensor or scanner and provides a variety of tactile and other feedback means for the subject user in order to make it easier to "find” the right position again, even after substantial time has passed between enrollment and the next authentication event.
  • Previous devices to locate fingers for fingerprint imaging focused upon the need to hold (literally press and flatten) the finger against a flat scanning surface and tended to either locate the finger crudely from the front edge of the nail or the skin crease under the first joint in the finger.
  • the intent was to substitute for the effect of rolling a print and pressure to flatten the finger was an important element.
  • Modern semiconductor sensors require only a light touch and, as noted, often focus on repeating the scan or capture of the same relevant portion of the fingerprint over and over again.
  • What is needed is a device that reduces the average number of attempts to authenticate known subjects by providing a simple circular, oval, rectangular, or square funnel like recess or guide for the finger that physically encourages the finger into the correct position opposite a scanner or sensor and may be further improved by providing a variety of tactile, mechanical movement, audio, or visual feedback means for the subject user in order to make it easier and more natural to "find" the right finger position again, even after substantial time has passed between enrollment and the next authentication attempt.
  • this false reject rate for untrained subjects can range from ten to fifteen percent of all attempts.
  • the preferred embodiment of the finger guide device invention is designed to relocate a relevant portion of the finger between .20 and .90 inch in distance from the underside of the fingernail in alignment with a sensor or scanner, and, as such, locates from the finger tip rather than the ridge under the first joint in the finger.
  • the finger guide device top edge at the front is of a low enough profile to avoid contact with the fingernail. Such contact would introduce error because subjects trim their nails to different lengths and most would also find pressure against the nail tip uncomfortable, both conditions having been found in previous devices claimed to help position a finger upon a fingerprint reader or scanner.
  • the physical design of the finger guide device enables sufficiently accurate placement of the finger over the sensor to facilitate a substantial increase in the percentage of first time acceptance (of enrolled subjects), said result being equivalent to reducing the percentage of false rejects.
  • This preferred embodiment includes a relatively short concave radius (or relatively steep slope) at the front of the finger guide device where the finger tip just below the finger nail touches or is proximal to the front of the finger guide device and a longer radius concave shape (or less steep slope) adjacent to the opposite side of the sensor where the guide extends up the finger towards the body.
  • the portions of the sides opposite the scanner or sensor are quite steep to keep the finger centered laterally.
  • the finger guide device is sized for an average finger, yet accommodates a wide range of digit sizes because it only interfaces with a small curved portion of the finger or digit, said portion to include a relevant portion of the finger.
  • the finger guide device of the present invention for both enrollment and authentication enhances the efficacy of the finger guide device in actual practice and application. This is because the natural feel of the finger guide device non-forcibly and ergonomically guides users to approximately the same position or alignment of a relevant portion of the finger with the active sensor area each time. This guiding process is both physical and neural, providing tactile feedback that is important to first use and subsequent learning.
  • the system may ask the subject to touch and remove the finger several times.
  • the finger guide device is generally designed to accommodate fingers, thumbs, or any digits from left or right appendages. This means that it aids placement but does not strictly limit placement to an exact and repeatable placement; instead, it simply brings the placement within the tolerance ranges of the sensor and fingerprint template matching algorithm.
  • Additional embodiments of the invention may include feedback mechanisms including those designed to alert (and train) subjects regarding the correct positioning of their finger or feedback designed to alert subjects to the fact that they have been accepted into the system (which is to say that their fingerprint has been scanned, compared, and correctly matched). Sound may be used to "guide" the finger to the sensor. Visual indicators may also be used. Examples include but are not limited to icons, marking of a fingerprint drawing, fiducial markings, light sources (such as LED's), and colored circles.
  • These feedback mechanisms may also be used to correct misuse of the system. For example, extreme pressure on the sensor or a lack of touch pressure can cause scanning problems. Overpressure can flatten minutiae and saturate the sensor and cause inability to resolve minutiae accurately. Conversely, the lack of pressure in the form of too light a touch may cause the minutiae to remain irresolvable by the sensor so that good image cannot be generated.
  • a voice command or sound or vibration or other feedback means could be used to communicate the need to relax the grip or even to press or squeeze a bit harder. Said feedback means may communicate to the subject the need to lighten up touch pressure or lift the finger a bit.
  • click feedback means may require that a user apply the minimum acceptable pressure required for the scanner or sensor to "see” a relevant portion of the finger.
  • Another viable approach is to move the sensor up or down slightly in the finger guide sensor window in order to adjust for differences in finger pressure on the scanner or sensor.
  • a preferred method of practice for this invention is an assembly with the sensor and finger guide designed to work together as one unit, which is to say a system. This requires configuring the sensor for operation on a circuit board, likely containing additional support circuitry for its application.
  • the combination of finger guide, sensor, sealing gasket, and printed wiring board with connector may or may not be placed in its own housing. As such, this subassembly may be placed in a variety of devices for its application.
  • the unit is a security platform with a plurality of uses. Examples include but are not limited to vehicle doors or dashboards, countertops, doors or doorframes, keyboards, personal digital assistants, telephonic devices, secure fax machines, computing devices, appliances, instruments, machinery controls, medical devices, cash registers, and much more.
  • Fingerprint sensors or scanners use a variety of solutions to sense and capture image data detailing the unique individual features of a human fingerprint minutiae or the living minutiae tissue directly under the fingerprint.
  • finger and fingerprint are intended to refer to any digit and its unique minutiae from left or right appendages and to be the same and equivalent to the use of the word thumb or thumbprint.
  • the use of the words he and his are not intended to be gender specific and are intended to be equivalent to she or her.
  • the finger guide device of the present invention may be used as a device to provide inputs to a system from a user.
  • This embodiment of the present invention would include mechanical communication of the finger guide device to one or more pressure sensors or electrical capacitive sensors to sense when the finger guide device is touched or pressed.
  • When the device is touched it may serve as an input or switch control device and when the device is pressed in one or more directions and with varying pressure or surface contact movement, it may serve as a proportional input device to facilitate a variety of input applications including but not limited to controlling machinery or equipment or as a pointing device for a computer.
  • Placement of a finger in the finger guide device and applying pressure in axial or lateral directions or combined directions will allow a second utility use of the finger guide as a pointing device when the finger guide device is in communication with pressure sensors or switches.
  • Changing or moving the points of touch contact with the sides of the recess will also facilitate utility use of the finger guide device as a pointer or control device if the surface contains sensors to detect the changes, said touch sensor means being known to those skilled in the art of producing touch sensitive pointing and control devices and herein are incorporated by reference rather than recited here in full detail.
  • a user subject may be under duress during use of the finger guide device of the present invention; for example, a crime might be underway wherein a user might be at gunpoint and forced to authenticate against his will.
  • the user is experiencing another type of emergency, or even forced illegally to use the device, then he may use his "911 " digit to call for help.
  • the system cannot match the enrolled fingerprint, but it will recognize a match with the user subject's emergency finger and therefore recognize the need to respond differently and accordingly.
  • FIGURE 1 discloses a preferred embodiment of the finger guide device of the present invention mounted in alignment with a fingerprint sensor and mounted in a commonly used biometric touch pad similar to fingerprint touch pads ordinarily used with computers for the purpose of identifying and authenticating system users;
  • FIGURE 2 is an assembly drawing of the preferred embodiment of the finger guide device of the present invention of FIGURE 1 comprising the finger guide device, gasket, aligned fingerprint sensor with drive ring, and printed circuit board;
  • FIGURE 3A discloses an overhead view of the preferred embodiment of the finger guide device of FIGURE 1 , with a finger mounted thereon, the finger being positioned onto the finger guide device and a relevant portion of the finger in alignment with the fingerprint sensor in order to enable matching of a relevant partial fingerprint with the matching template; and

  • FIGURE 1 the preferred embodiment of finger guide device 12 of the present invention is shown in alignment with a fingerprint sensor 16 wherein both the finger guide device and fingerprint sensor reside in a simple touch pad 26 housing to sit on a desk, countertop or other surface.
  • This simple fingerprint pad configuration of the preferred embodiment is normally used with a computer or terminal or payment cash register to identify a subject in order to grant access to data, files, or network communications or to identify the subject for another purpose; for example, completing a payment transaction.
  • the touch pad combined with the computer and fingerprint matching software algorithm is a fingerprint identification system.
  • the finger guide device reduces the number of false rejects experienced during repeated use of the fingerprint identification system.
  • FIGURE 2 discloses an inverted assembly drawing of the preferred embodiment of the finger guide device 12 of the present invention comprising the finger guide device 12, gasket 14, sensor 16 and drive ring 17, and printed circuit board 18.
  • the left and right sides of the finger guide device next to the sensor area are steeper than the front (lower portion in FIGURE 2) and back (upper portion in FIGURE 2) and of a concave nature in this embodiment.
  • the front portion of the finger guide device is concave from the sensor alignment portion to the top ridge and has shape derived from a short set of radii to create its generally concave contour. The fingertip will contact this front portion of the finger guide device (see next FIGURE 3B).
  • the sides of the finger guide device form a recess that receives the finger of the user and guides the finger laterally to center a relevant portion of the print over the fingerprint sensor 16 and drive ring 17. Accordingly, the sides of the finger guide device have the same general shape as the finger.
  • the sides are concave, having a varying radius of curvature. This includes a relatively short concave radius (or relatively steep slope) at the front of the finger guide device where the finger tip just below the finger nail touches or is proximal to the front of the finger guide device and a longer radius concave shape (or less steep slope) adjacent to the opposite side of the sensor where the guide extends up the finger towards the body.
  • the finger guide device is sized for an average finger, yet accommodates a wide range of digit sizes because it only interfaces with a small curved portion of the finger or digit.
  • the finger guide device has a plurality of flat sides, said opposite sides being of equal slope while still practicing the present invention in this second preferred embodiment.
  • the drive ring is equivalently exposed and the finger guide device 12 is used as a supplement to the drive ring and is conductive and reflective of electromagnetic energy. This feature is desirable but not required for the finger guide device to function.
  • the finger guide device is non-conductive yet the electrical signal provided by the drive ring is itself sufficient to illuminate the relevant minutiae portions of the fingerprint wherein the assembly functions sufficiently but not necessarily optimally.
  • the front portion of the finger guide device 12 serves as a stop and location reference designed to meet the fingertip or thumb below the nail and avoid differences in position which could result from differences in length of the subject user's finger or thumbnail. This is a distinct advantage over devices that clamp over or cross over the top (nail) side of the finger.
  • FIGURE 3A discloses an overhead view of the preferred embodiment of the finger guide device 12, with a finger mounted thereon, said finger being positioned onto the finger guide device so that a relevant portion of the finger is in alignment with the fingerprint sensor 16 and therefore enabling accurate matching of the relevant portion of the fingerprint; and
  • FIGURE 3B discloses a side view of the steep forward slope 27 of the finger guide device 12 aligning the finger in an axial position with a relevant portion of the finger in alignment with the fingerprint sensor and therefore enabling accurate matching of the relevant partial fingerprint portion.
  • the top edge of the finger guide device is lower than the extension of a long fingernail so that the fingernail will not contact the finger guide device. This feature avoids the possibility of misalignment caused by differences in fingernail length that might occur between enrollment and later use of the finger guide device, either from normal fingernail growth or trimming of the fingernail during the time between enrollment and use of the finger guide device.
  • the finger guide devices of the present invention in any of its various preferred embodiments described herein may also use physical elements and specific material properties to discourage improper use.
  • the preferred method of practicing this invention shown in FIGURE 1 surrounds the finger guide device 12 with a relatively hard and distinct ridge. While not felt as dangerously “sharp" this ridge is intended to be felt as uncomfortable. When a finger is placed across this ridge, while not harmful, it is not comfortable because it applies a high pressure per square inch (PSI) to the skin across a very narrow area. This high pressure per square inch signals through the sense of touch that the finger is not being positioned correctly in the recessed area.
  • PSI pressure per square inch
  • the feel of the misaligned finger is meant to feel unnatural and the user will instinctively reposition his finger to find a more natural and comfortable feel.
  • the natural tendency is to avoid placing the finger against the outer ridge of the finger guide device, instead easily sliding the finger or thumb down comfortably and non-forcibly into the finger guide device and onto the sensor (the desired position).
  • the material property of high thermal conductivity may be used to cause any of the preferred embodiments of the finger guide devices disclosed herein to feel colder to the touch than the surrounding surfaces and the sensor surface. Although all surfaces are normally at the same temperature, the ability to draw heat from the skin (thermal conductivity) creates the feeling that something is cold. For example, by stipulating a finger guide device (or surface coating) made of metal (or other thermally conductive material such as ceramic or nanoparticle ceramic paint), any of the preferred embodiments will have this property of feeling colder than the surrounding surfaces provided that the surrounding surfaces are of a material with a lower thermal conductivity, such as plastic or cloth. The result is the subject user's tactile feedback based ability to distinguish the finger guide device surfaces from other surfaces and thereby guide his finger onto the finger guide device.
  • any of the preferred embodiments of the finger guide devices disclosed herein may be designed to work with active feedback mechanisms including those designed to alert subjects or to train subjects regarding the correct positioning of their finger or with other feedback means designed to alert subjects to the fact that they have been accepted into the system (which is to say that their fingerprint has been scanned, compared, and correctly matched). Sound or voice commands may be used to instruct users how to "guide” the finger into proper alignment with the sensor. Active or passive visual indicators may also be used with any of the preferred embodiments of the finger guide devices disclosed herein. Examples include but are not limited to light indicators, icons, fingerprint drawings or markings, indicia markings, text instructions, or colored markings, wherein such indicators are known to those skilled in the art of human factors engineering and are herein incorporated by reference. Finally, physical movement used as a mechanical movement feedback mechanism such as vibration or "click” may be applied much like the stick shaker that alerts pilots of a stall warning when flying a plane, such mechanical movement feedback means being known to those skilled in the art of human factors engineering.
  • Yet another preferred embodiment of the finger guide device is in communication with the system computer to make a real time determination of the need to move the sensor in closer or further proximity to the plane at the bottom of the recess and thereby in closer or further proximity to a relevant portion of the finger or living minutiae tissue, and thereby resulting in a real time optimization of the image of a relevant portion of the fingerprint, regardless of whether or not pressure is the determining factor in image optimization.
  • the disclosed real time adjustment may be related to focal length rather than contact pressure; or, if a sensor detecting sub-surface tissue properties is used, then the pressure against the finger causing reduced blood circulation may require adjustment.
  • this emergency digit match is taken as an instruction to trigger so-called "silent alarms" to provide immediate aid (e.g. police assistance).
  • the system rather than reject the user subject, could be programmed to appear to malfunction, or for other revealed reason than subject's failure to authenticate, be rendered unable to complete the desired security controlled event or otherwise delay the event to allow extra time for assistance to arrive, such approach intended to minimize the risk to the subject under duress.

Abstract

L'invention porte sur un dispositif de guidage du doigt permettant de positionner de manière optimale le doigt (ou un point caractéristique du doigt) d'un sujet sur un capteur d'empreintes digitales en vue d'une opération d'authentification ou d'identification dudit sujet, et plaçant la partie intéressée du doigt en alignement sur un capteur ou un lecteur, l'authentification ou l'identification s'obtenant par comparaison d'empreintes. Le dispositif de guidage peut également servir à l'enregistrement initial de données d'empreinte dans le système, et à leur traduction en modèle à des fins de comparaison ultérieure. Le dispositif de guidage peut également servir à mesurer la température et à en fournir un équivalent tactile ou sous d'autres formes à l'utilisateur. La surface extérieure du dispositif de guidage peut présenter une nervure rendant le toucher inconfortable lors qu'une pression élevée au cm2 s'applique sur de petites surfaces du doigt mal positionné de l'utilisateur de façon à l'encourager à placer correctement le doigt dans une position plus confortable. Le dispositif de guidage peut présenter une surface intérieure incurvée pouvant entourer plusieurs formes ou tailles de doigts et dont les côtés et la partie frontale ont un rayon de courbure inférieur à celui de la partie arrière. La partie frontale peut présenter un pente suffisante de ses côtés et un rayon de courbure plus petit pour bloquer l'extrémité du doigt à environ 0,2 à 0,9 pouce du centre du capteur, ce qui est la position idéale pour enregistrer puis authentifier ou identifier l'utilisateur. Le matériau ou la surface du dispositif de guidage peut être électroconducteur et donc servir à transmettre un signal de commande aux tissus du doigt pour faciliter l'utilisation de capteurs d'empreintes, capacitifs ou autres à commande électronique ou électromagnétique demandant ce type de détecteur de potentiel électrique. On peut également prévoir d'autres améliorations tactiles telles que des bosses de positionnement jumelles, ou des informations en retour en Braille ou audio ou à déplacement mécanique, ou des marqueurs visuels ou à voyants lumineux. On peut en outre abaisser ou élever le niveau du capteur ou du lecteur pour modifier les données de saisie, et utiliser le dispositif de guidage pour des communications avec des dispositifs électromécaniques lui permettant d'assurer la fonction de commutateur ou de dispositif de pointage.
