Abstract

A finger guide device (figure 2) that positions a finger of a subject on a fingerprintsensor in a manner optimal for the operation of authentication while graspinga stylus (10) or pen. Authentication takes place by fingerprint matching. Thefinger guide (12) non-forcibly guides the subject finger into a position wherea relevant portion of the finger is aligned with the fingerprint scanner (16)so that said relevant portion will correlate with generally same relevant portionsof the fingerprint previously translated into the template.

Description

DEVICE GUIDE TO USE WITH PENCIL PHOTOSENSIBLE PEN OR PEN FIELD OF THE INVENTION The invention relates in general to a finger guide, called a finger guide device, used to place a finger, thumb or human finger containing unique minute details on a scanner or sensor or other means to capture an image of the characteristics miniatures of a relevant and substantial portion of the minute details, which is equivalently termed a fingerprint. This finger guide device would be used with electronic, optical, electrolumm, electromagnetic, capacitive, pressure-based or similar sensors or scanners, which require repeated and reasonably accurate placement of the finger in alignment with the scanner or sensor, the sensor or Scanner is placed in a photosensitive pen or pen. Applications include the precise authentication or identification of an individual or a specific finger of an individual, with a minimum number of false rejections or repetitions of the process to scan, detect, or capture a relevant and previously recorded portion of the fingerprint.

BACKGROUND OF THE INVENTION U.S. Patent Application No. 2004101172 (Lane) discloses a fingerprint registration system for receiving a finger of a person to be printed as a fingerprint by an automatic fingerprint reader. The system includes a fingerprint recording device, which has a receiving portion of the finger to receive the finger to be printed as a fingerprint. Extending outward from the receiving surface of the finger, there is a locator bar which couples a line of the skin of the object finger when it is approximately in the desired position. U.S. Patent Application 2004101171 (Lane et al.) Discloses a fingerprint registration system for receiving and holding a finger of a person, which is printed as a fingerprint by an automatic fingerprint reader. The system includes a fingerprint recording device having a finger receiving portion and a finger placing portion, together forming a gap of reduced dimension, such that a forcibly inserted subject finger is held in a stable position. And finally, U.S. Patent Application No. US2004076314 (Cheng) discloses an apparatus that includes a fingerprint sensor and a guiding means. The place Fingerprint sensor detector produces an obtuse and relative angle with a guiding plane of the guiding means. Traditionally, in order to register a fingerprint, ink was applied to a finger and then the finger was "rolled" through a paper or other ink receiving surface, to print an image of the fingerprint. The fingerprints transferred by touching a surface and leaving oily residue are captured in a forensic manner by various process techniques that "transfer" and reveal the fingerprint. In more recent years, alternative technologies have been developed that can reveal the fine characteristics within a fingerprint and capture the fingerprint directly from the finger or the tissue beneath the surface of the skin of the finger that grows outward to form the details minute finger Electronic sensing technology involves holding the finger in a sensor system as the system detects skin or tissue differences through the finger area or just in a portion of the finger area, in order to reveal an image of the fingerprint or in order to create an electronic representation of the fingerprint, for example as a digital file. Examples include, optical scanners, electroluminescent pressure sensitive systems, integrated circuits with the ability to measure the capacitance dimensioned by individual pixels, etc. The production cost for some types of fingerprint scanning systems depends on the size of the fingerprint area to be detected. This is especially true for silicon-based sensors or integrated circuit type (IC, for its acronym in English) . As in most ICs, the larger the IC, the more expensive it is to produce it, assuming device geometries and layer counts, the same. The production cost of the sensor is directly related to the sensor area, and to the mass production of sensors, the size of a thumb is not optimal when only a relevant portion of a finger needs to be scanned, in order to build an authentication system. Fingerprints. If only a relevant portion of the fingerprint is to be used in order to reduce the cost of the system, then it becomes important to place practically the same relevant portion of the finger that was originally registered on the sensor for each authentication or identification event. Obviously a smaller sensor would cost less and, assuming that the detected finger area is by necessity large enough to provide an acceptable level of safety or comparison capability, then the optimal solution would be this smaller sensor, leaving out significant portions of the total fingerprint area. The finger guide device of the present invention is a device that can be used to reliably relocate a finger over a small sensor to enable more efficient identification. The device reduces false rejections caused by the deficiency to place the finger close enough to its position or original registration positions. The finger guide device ensures that the sensor can read relevant portions for comparison of the fingerprint, to generally stipulate the reading of the same relevant portions as those captured and stored in a template used for comparison and matching. The finger guide device reduces the incidence of false rejections by guiding naturally (eg, comfortably and intuitively) and not necessarily the object finger to approximately (generally) the same original registration position, each time the fingerprint identification system is used digital When smaller sensors are used, if the finger is recorded in a manner that scans a relevant portion of the finger, or perhaps several overlapping portions of the printed area of the finger, which are then assembled electronically by a computer in a "template" completed, which represents a larger area of the subject's original fingerprint, than any simple scanner could produce alone, then the system depends on the subject user who is able to touch the sensor consistently in the same approximate place, so that a portion relevant for comparison of the finger is read by the sensor, so that accurate authentication can happen. The deficiency to reposition the finger precisely in the same place generally causes false rejections; or, in other words, because the sensor observes an irrelevant and different area of the finger, it can not compare with the data of the relevant portions of the fingerprint previously recorded in the template, and rejects an acceptable, known subject user. This is a false rejection. If the system allows additional attempts, and if the second or subsequent tests finally align the minute details that contain a relevant portion of the fingerprint, compare a portion originally stored during registration, the subject will be accepted (identified or "authenticated"). The finger guide device reduces the average number of attempts to authenticate known subjects by providing a funnel guide, generally oval or rectangular, simple, for the finger, which physically aids the finger in the correct position, and provides a variety of means tactile feedback devices for the subject user, in order to make it easier to "find" the correct position again, even after substantial time has elapsed between the registration and the next authentication event. In contrast, with basic flat surface sensors or sensors surrounded by generally planar surfaces or poorly designed sensors, this false rejection ratio for untrained subjects can range from ten to fifteen percent of all attempts or even greater with different installations. systems.

SUMMARY OF THE INVENTION Almost like a funnel generally round, oval, square, or rectangular, guides a fluid towards a container, the finger guide device or "depression" for the finger (hollow) serves to guide the finger towards the same position towards the same position on the sensor in a repeatable way. Another simple analogy is to describe a sphere at the tip of a pyramid, which is unstable versus a sphere that rests on a global minimum in an inverted or hollow pyramid, where the sphere always rotates to the same global minimum position through the gravity action and the side walls of the hole. In the case of the fingerprint device, one less action is initiated obvious by muscles that apply reasonable force to easily slide the finger towards the sensor area, such movement is guided by the described physical, material, and tactile elements, in the finger guide device to guide the finger to the same site each time through of the communication to the subject user and the natural movement towards the site is also effected by the tactile feedback from the ergonomically designed side walls of the device. The sensor would be positioned within a window at the bottom of the finger guide device in the correct position and adjacent to the relevant desired area of the finger, in order to "see" the preferred portion (projection) of the fingerprint. Prior devices for placing fingers in order to form the image of the fingerprint focused on the need to hold (literally press) the finger against a flat scanning surface and tended to either place the finger roughly from the front edge of the nail or the lines of the skin under the first joint on the finger. The attempt to replace the effect of recording an impression and pressing to flatten the finger was an important element. Modern semiconductor sensors require only a light touch and, as noted, frequently focus on repeating the scan or generally capturing the same relevant sections of Fingerprint over and over again, as long as the finger usually stays in active alignment with the sensor. The invention provides an effective aid and a learning mechanism that helps the subjects in the placement of the finger in the correct place, on a repeatable basis with the relevant portions of the finger in alignment with the scanner or sensor and to develop the correct touch (pressure ) as well as through a group of media that include physical form, feedback means, and material properties. In addition, the device is designed to unintentionally reposition an area of the finger between 5 mm and 22.8 mm (0.20 and 0.90 inch) away from the underside of the nail, and, as such, locates from the tip of the finger under the nail, instead of the edge under the first joint on the finger. In addition, the edge of the finger guide device on the front is of a sufficiently low profile to avoid contact with the nail. Such contact would introduce error, because different subjects fix their nails to different lengths, sometimes at different times, and most would also find it uncomfortable to press against the tip of the nail, both conditions have been found in the previous devices, to help the placement of a finger on a fingerprint reader or scanner. The physical design of the fingerprint device it makes possible the sufficiently precise placement of the relevant portion of the finger on the center of the sensor, to facilitate a substantial increase in the percentage of acceptance for the first time (of registered subjects). This includes a relatively short concave radius (or relatively steep slope) at the front of the finger guide device, where the tip of the finger just below the finger touches or is near the front of the finger guide device and a concave shape of longer radius (or less steep slope) adjacent to the opposite side of the sensor, wherein the concavity extends above the finger towards the body. The sides are very tilted on either side of the scanner or sensing area to maintain the relevant portion of the finger, centered laterally on the scanner or sensor. In general, the finger guide device is conformed to the size of an average finger, but accommodates a wide range of finger sizes, because it only interconnects with a small relevant portion of the finger. The tolerance allowed for the placement of the finger on smaller electronic sensors, mounted on flat surfaces is very liberal, but the placement of a relevant portion of the finger on these devices without the benefit of the finger guide device, remains a challenge for the subjects not trained. This could be limited in about half to two thirds of the finger print area, which will be scanned as overlapping with other relevant portions of the previously scanned fingerprint that exists in the template, depending on the algorithm used and the accuracy of the system. Systems with low accuracy can operate even with less than half an overlap of the sensor window, between an authentication scan and its corresponding relevant portion within the stored template. The actual relevant portion, required for a secure comparison, depends on the algorithm and, within the algorithm, the actual desired security level or the security establishment. This is related to the relevant portion of the scanned subject's impression, which correlates with the subject's registered template. The ability to place the same relevant portion of the print opposite to the active area (window) of the sensor on a consistent and repeatable basis helps to quickly and accurately facilitate the first test comparison and this substantially reduces the proportion of false rejections. The finger guide device of the invention reduces false rejections among registered subjects, but have no practice, to less than 10%. Practicing the fingerprint device or optimizing the system or combining them both will further reduce the proportion of false rejections; and low ideal conditions with an optimized system, the finger guide device in a photosensitive pen or pen can reduce false rejections to less than 2%. This reduction in the proportions of false rejections from a range of between 10% and 20% of tests and that has an average of approximately 15% to less than 2%, constitutes a significant difference in the acceptance and the commercialization capacity of a system security based on pen or photosensitive pencil. The frustration in the subject user population is substantially reduced if people do not need to touch the sensor several times to be accepted. This is particularly important in a photosensitive pen or pencil application, where the user's special ability to raise and reposition the finger is often required for each additional authentication attempt. As an aid to reduce the demands of special dexterity and help facilitate this required physical handling of the device, some fingerprint-equipped pens include special flexible handles or non-flexible handle surfaces. At the end of 2003, a new keyboard was introduced for approximately 250,000 users and there was no solution as a fingerprint guide. There was considerable frustration in the user base and the company that developed the system He faced considerable criticism. Such problems caused users to question how well a system works, although the problem can be technically called user error or user failure, due to the inaccurate placement of the finger (misalignment with the sensor) during the authentication process. The finger guide device reduces this expected error of the user and increases the probability of acceptance of the subject at the first touch. This saves a lot of time in the life of a system and is a critical element in developing biometric systems that are consistently competitive, with keywords or personal identification numbers (PINs) in terms of user time and efficiency. Using the finger guide device for both registration and authentication, increases the effectiveness of the finger guide device in actual practice and application. This is due to the natural feel of the finger guide device, which guides users ergonomically to approximately the same position or alignment of a relevant portion of the finger above the active sensing area each time. This guiding process is both physical and neural, so it provides tactile feedback that is important for the first use and subsequent learning.

During registration, the system may ask the subject to remove the finger and have the finger touch the scanner or sensor several times (for example, "lift and reposition" the finger). The finger guide device is generally designed to accommodate fingers or thumbs of the left or right limbs. This means that it helps this multiple placement, but does not strictly limit accurate and repeatable placement accurately, it simply gives the placement within the tolerance ranges of the sensor and the algorithm, so that a relevant portion of the subject's finger is aligned opposite to the scanner or sensor. This allows the template to extend beyond the strict limits of the ideal or "perfect" window box (projection) and thus creates a template that has a safety band designed to accommodate reasonable levels of future misalignment within the capacity of tolerance and guidance of the finger guide device. This function is important for repeatable and long-term performance, and the improved alignment facilitated by the finger guide device only needs to be raised to the limits required by the comparison system, including without restriction, the dimensions of the template and the level of safety of the algorithm. Some sensors boost an electric potential or electromagnetic signal towards the tissue of the finger. This can be a radiofrequency signal. The finger guide device or its surface can be electrically conductive to assist these applications during registration and subsequent authentication events. The finger guide device can be designed in a preferred embodiment, with a generally parabolic shape to focus the electromagnetic energy reflected on relevant portions of the finger, in a process called illumination and to improve the characteristics of the information that is detected. The properties of the surface and the material selected for the finger guide device are important for performance. Since the finger must slide easily in position, the low coefficients of friction (both sliding coefficient and static coefficient) are useful to allow the finger to be supported in its natural global minimum, which is at the bottom of the finger guide device , properly placed on the scanner or sensor. This property of the surface and resulting process places the finger in the same place next time again. Examples of materials with suitably low friction coefficients include, without restriction, smooth metals, smooth plastics, and even painted, polished, or waxed surfaces. If he Surface material has a high coefficient of friction, for example, rubber, urethane-based material, or rough plastics, the utility and function of the finger guide device can be reduced or compromised. Lubricants and waxes, wet or dry, can also be applied, and suitable lubricants can also be mixed in cleaning solutions or special cleaning cloths. Other feedback elements may be included in preferred or alternative embodiments of the present invention. Humans will develop the ability to feel the correct position, as they gain experience with the finger guide device. The finger guide device can be made of a material with a high thermal conductivity, to provide tactile feedback and to accelerate this learning process. Examples include without restriction metals, certain ceramics, or certain carbon-based materials. In this case, the finger guide device would tend to give the sensation of coldness in the touch at room temperature (related to other parts of the pen or photosensitive pencil), not because of its absolute temperature, but because it has a thermal conductivity that leads Rapidly heat the skin outside when touched, therefore quickly cools the sensitive surface of the finger after contact. If he Fingerprint device is made of metal, this property will make it feel like metal to the touch (for example, cold feeling). When feeling colder than the rest of the pen and cooler than the silicone sensor and its surface coating, the subject will learn the correct "feel" of the finger guide device and also feel the sensor better. Additional bumps can be added to help orient the finger or enable subjects to "fine-tune" their finger position. These may be unnecessary for normal or average sized fingers, but may be useful in applications where subjects have very small fingers, which have little contact with the surface area of the finger guide device. Braille can be added to the finger guide device to help blind or low vision users. The finger guide device can also use physical elements and material properties to discourage inappropriate use. For example, a preferred method for practicing this invention surrounds the finger guide device with a relatively hard and distinct edge. While not feeling dangerously "sharp", this edge is designed to make the subject user feel uncomfortable. When a finger is placed Through this edge, while not dangerous, it is uncomfortable because it applies a high pressure per square inch (measured for example in "psi") to the skin through a very narrow edge line. This great pressure per square inch indicates through the sense of touch that the pen is not being held correctly. The feeling of the misaligned grip is to feel it unnatural and the user will instinctively reposition his grip to have a more natural and comfortable feeling. The natural tendency is to avoid holding the pen against the outer edge of the finger guide device, instead of sliding the finger or thumb down the finger guide device and over the sensor (the desired position). This is in the correct position when holding the photosensitive pen feels both natural and secure (stable) the subject user. The words "photosensitive pencil" or "pen", sometimes used interchangeably and as equivalents, as used herein include any elongated instrument, held or held by a user, and capable of writing on a surface. Additional embodiments of the invention may include feedback mechanisms that include those designed to alert (and train) subjects about the correct position of their finger, or feedback designed to alert subjects Regarding the fact that they have been accepted into the system (ie their fingerprint has been scanned, compared, and correctly matched). Sound can be used to "guide" the finger to the sensor. You can also use visual indicators. Finally, physical movement as a vibration, can be applied almost as the indicator of loss of speed that alerts pilots to an indication of near collapse when driving an airplane. In another preferred embodiment of the finger guide device, a movement responsive to pressure can be used with a feedback "click", such as a tactile (and audible) feedback signal to tell the user when the finger is in the guide with the adequate range of applied touch pressure. These feedback mechanisms can also be used to correct improper use of the system. For example, extreme pressure on the sensor or a lack of touch pressure can cause scanning problems. Occasionally, subject users, perhaps frustrated by a false rejection, may incorrectly conclude that greater pressure on the finger will cause the system to function better. The overpressure can flatten minute details and saturate the sensor and cause the inability to accurately resolve the details meticulous. Of way contrary, the lack of pressure in the form of a very light touch can cause the minute details to remain unresolved by the sensor, in such a way that a good image can not be generated. In any case, an order of voice or sound or other means of feedback known to some expert in the technique of human factors engineering or ergonomics, could be used to communicate the need to relax the grip or even to press or tighten a little more strong. The feedback means by voice or sound or others can communicate to the subject the need to make the touch pressure lighter or raise the finger slightly. Another viable solution is to move the sensor slightly upwards or downwards in the sensor window of the finger guide device, either by manual adjustment or automatically using an actuator system and with feedback control loop, such means are known to the experts in the technique of electromechanical feedback control systems. A preferred method for practicing this invention is a unit with the sensor and finger guide device, intended to work together as a unit, i.e. as a system. This requires configuring the sensor for operation on a circuit board, which probably contains additional support circuitry For your application. The combination of the finger guide device, sensor, gasket, and printed circuit board with mounting means can be placed in the housing of a photosensitive pen or pen. As such, this subunit can be placed in a range of different housing styles for photosensitive pencil or pen, for its application. The finger guide device of the present invention and a system for comparing a scribe's fingerprints can be combined with other biometric comparison methods to give a safer overall result. Examples include, without restriction, facial recognition, additional fingerprints, iris recognition, or retinal scanning. In another example, the verification of the dynamic signature or "DSV" by its acronym in English, captures and digitizes several elements of human signature, static and dynamic, during the physical reproduction of a human signature (signature) and statistically analyzes a range of parametric measurements of these elements, for comparison with the parametric data stored and identified, compiled from the previously reproduced signature data (signature template or even a group of identified signature templates). A comparison would arise in the authentication or identification of the subject through its reproduced signature. There are several ways to perform this dynamic signature verification, known to those skilled in the art, an example of such a method being taught and claimed in U.S. Patent 5,559,895 (Lee et al.), "Adapta tive. method and sys tem for real time see if ica tion of dinamic human signa tures ", where the measurements of the" personalized characteristics "in the form of static and dynamic measurements, are compared with the signature characteristics registered, to provide the" precise signature discrimination "and this patent and the related prior art are incorporated by reference herein. There is also a need to verify, perhaps from a remote site, that a known signer has actually registered his signature instead of an undesirable alternative script, such as the words, "I am opposed" or "I do not agree". In 2002 the Corporate Fraud and Accountability Act, also known as the Sarbanes-Oxley Act, included a requirement that certain officials in public corporations certify the filings of required financial statements; and, in turn, corporations may require support certifications from key managers at remote operation sites. Such presentations are usually under strict deadlines and therefore it is The ability to complete the support signing process electronically is desirable. The needs motivated by the Internet to facilitate many other forms of remote commerce, provide an equally compelling motivation for a verification method that has been reproduced a legally valid, real signature, which includes the same need to "require the adoption and use of signatures digital signatures by federal agencies and to promote the use of digital signatures in electronic transactions of the private sector "effected by the United States legislation, called US eSign Bill (electronic signature document of the United States) passed in October 2000, supporting the legal validity of electronic or "digital" signatures. Using an undocumented system, a single pen system sensitive to the fingerprint, would not prevent such an individual from writing "I refuse to sign" or some other deed that indicates their agreement, thereby representing their will. The detection of such exceptions would require the human revision of each registered signature (and perhaps even the comparison with a "signature card" presented), which is also subject to human error or oversight. Therefore, another preferred embodiment of the finger guide device of the present invention is to combine the fingerprint identification and authentication system with a fingerprint identification system. dynamic signature verification, used for the purpose of confirming that the authenticated subject actually signed a valid reproduction of his signature. A signer may be under duress during writing or signing; for example, a crime may be happening, where a clerk is in a gun and is forced to sign. In such a circumstance, it may be desirable for the clerk to have a different digit of emergency, registered to use it as an emergency signal, that the clerk is under duress or even illegally forced. In such a case, the system can not compare the registered fingerprint, but will recognize a match with the clerk's emergency finger and will recognize the significance of this coincidence as a danger communication from the subject scribe. The subject scribe could call this digit registered specially "finger 911". This coincidence with finger 911 or emergency digit can be processed as an instruction to activate the so-called "silent alarms", in order to provide help (for example, police assistance) to the subject scribe. In addition, the system, instead of rejecting the clerk, in the alternative might seem like a malfunction or for another reason that the failure of the subject scribe to authenticate, makes it impossible to complete the transaction or otherwise delay the pending transaction until the arrival of emergency assistance (eg, the police), such method is intended to minimize the risk of harm to the undersigned clerk. Fingerprint sensors or scanners use various solutions to detect and capture detailed characteristics of human fingerprint capture image data. In this description, the use of the words finger and fingerprint, is intended to be the same and equivalent to the use of the word thumb or thumb print and refers to minute details or living tissue that protrudes to become minute details superficial of any finger of any left or right extremity of a subject user. In this description, if a subject user is named as he or she or he or she, it is intended that the use of these words be the same and equivalent, without any gender designation. For a more complete understanding of the finger guide device of the present invention, reference is made to the following detailed description and to the accompanying drawings, in which the currently preferred embodiments of the invention are shown by way of example. Since the invention can be exemplified in various forms, without departing from the spirit of the essential characteristics thereof, it is expressly understood that the drawings are for illustration and description purposes only, and are not designed as a definition of the limits of the invention. Throughout the description, similar reference numbers refer to the same components in all the various views.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Now with reference to the drawings, in the figure 1, the finger guide device (12) appears at the top of the exploded view just below the top cover (22), and contains several elements preferred. These include left and right sides steeper than the front and back of a concave nature, particularly in the areas near the fingerprint sensor (16). The front of the finger guide device is concave from the sensor window to the upper edge and has the shape derived from a short group of spokes to create its generally concave outline. The spokes of the posterior section create the less steep concave contour and are formed to embed the portion of the finger or digit between the preferred impression and the rest of the digit adjacent to the body. The end of the finger guide device beyond the nail contains a continuation of the feedback edge, but is not intended to use the joint of the finger or the edge of the skin under the joint, as a means of placing the finger adjacent to the sensor ( 16). The sides of the finger guide device form a gap that the user's finger receives. Accordingly, the sides of the finger guide device have the same general shape as the finger. In this first preferred embodiment of the finger guide device of the present invention, the sides are concave, have a variable radius of curvature. This includes a relatively short concave radius (or relatively steep slope) on the front of the finger guide device, wherein the tip of the finger just below the nail touches or is proximate to the front of the finger guide device and a concave shape of longer radius (or less inclined slope) adjacent to the opposite side of the sensor, wherein the guide It extends above the finger towards the body. The sides are very slanted in the area of the fingerprint sensor, to keep the finger centered laterally. In general, the finger guide device is sized for an average finger, but accommodates a wide range of finger sizes, because it only interconnects a small portion of the finger or digit. The finger guide device (12) contains a window for the sensor (16) and drive ring (17) to reveal these elements in alignment with a relevant portion of the digit or finger of the subject. The AES3400 sensor or AES3500 sensor, both manufactured by AuthenTec in Melbourne, Florida, would also be suitable as fingerprint sensors to support within this window. This window may be sufficient to contain a drive ring necessary for certain types of sensors (shown) or it may cover the drive ring and replace its own electrical conductivity with that provided by a drive ring. Within the field of possible preferred modalities, this It may also be the case and its performance is equivalent, aesthetics is the only substantive difference. In Figure 1, the drive ring (17) is exposed in an equivalent manner and the finger guide device (12) is used as a supplement for the drive ring (17) and is conductive. In the field of possible preferred embodiments, the opening of the window may not be necessary for certain types of scanners or fingerprint sensors; nevertheless, alignment is a necessary element for all preferred modalities. The surface of the sensor lies on a plane with the upper part of the window in the lower portion of the hollow of the finger guide device (12) and in the same plane next to it; however, strict placement with this plane is not critical to performance, as long as the subject's finger can be in contact with both the finger guide device (12) and the sensor (16). The foldable and flexible nature of living fingers facilitates this within reasonable limits. Under some circumstances, performance can be further improved by adjusting the fingerprint sensor plane up or down to alter the characteristics of the fingerprint image. Since there is light utility gained from an optimal selection of the vertical positions, the finger guide device of the present invention works perfectly through a range of positions. A gasket (14) (or equivalent protective means) is provided to prevent the ingress of grease, fluids, dirt, or other unwanted material from the sensor guides and the circuit board. This sensor (16) is made of a material that is impermeable to solvents and other unwanted contaminants. Other protective materials can be replaced by a joint, such as conformal coatings applied in liquid form, which solidify or partially solidify to create a protective barrier. The invention works with various circuit board protecting means, available and known to those skilled in the art. The invention will work without a protective means. The finger guiding device (12) contains one or more mounting protuberances, shown in this preferred embodiment example as opposite and adjacent. These are used to align the finger guide device (12) with the sensor (16) and the board (14), with its printed connection board (18) or other mounting means and, in turn, to assemble the subunit of the device. sensor (16), the gasket (14), and the finger guide device (12) inside the housing of the photosensitive pen or pencil, comprises the upper cover (22) and is coupled under the cover (26).

This can be facilitated by any suitable mounting means, known to those skilled in the art. The front portion of the guide serves as a stop and reference location, designed to find the fingerprint or thumb under the nail, and avoid differences in position that could be caused by differences in the length of the finger or fingernail . This is a distinct advantage over devices that are fastened on or through the upper side (fingernail) of the finger. Figure 2 shows a finger guide device (12) and fingerprint sensor system (16) in a photosensitive pencil housing (10). The finger guiding device (12) is unfolded and the elements shown include the left and right sides steeper than the front and back, where they are close to the sensor and are of a concave nature. The front is concave from the sensor window to the upper edge and has the shape derived from a short group of spokes, to create its generally concave outline. The fingerprint will be in contact with this front portion of the finger guide device (12). The radii of the posterior section create the less steep concave contour and are formed to embed the portion of the finger or digit between the preferred impression and the remainder of the digit adjacent to the body. The end of the guide device finger (12) beyond the nail, contains a continuation of the feedback rim, but is not intended to use the joint of the finger or the edge of the skin under the joint as a means to place the finger adjacent to the sensor (16) . The finger guide device (12) contains a window for the sensor (16), to reveal by itself the alignment to the digit or finger of the subject. This window may be sufficient to contain a drive ring, necessary for certain types of sensors (shown) or can cover the drive ring and replace its own electrical conductivity with that provided by a drive ring. In the preferred modalities, this may also be the case and its performance is equivalent, aesthetics is only the substantive difference. In Figure 2, the drive ring surrounding the fingerprint sensor (16) is exposed in an equivalent manner and the finger guide device (12) is used as a supplement for the drive ring and is conductive. For certain types of scanners or sensors, the invention works without an open window. Examples may include, without restriction, optical scanners, sensors, certain ultrasonic sensors, Figure 3A describes a side view of the Preferred embodiment of the photosensitive pencil of Figure 1, which includes the finger guide device (12) of the present invention, the photosensitive pencil (10A) is wireless; and Figure 3B depicts a side view of a second preferred embodiment of the photosensitive pencil of Figure 1, including the finger guide device (12) of the present invention, the photosensitive pencil (10B) being attached. The finger guide device is shown emerging from the top of the top cover (22). A fastening pad (29) is described which is made of a soft and frictional material (relatively high coefficients of friction) intended to provide a more comfortable and stable hold. This non-slidable holding surface, coupled under the cover (26) helps the photosensitive pen to remain motionless, as the user removes and repositions the finger on the finger guide device, during registration or in the case of a second test after a false rejection Suitable flexible materials with high coefficients of friction are known to those skilled in the art and include, without restriction, rubber, urethane-based materials, and kid skin. Figure 4A describes a top view of the preferred embodiment of the finger guide device (12) of Figure 1, with a finger mounted on it, the finger is placed on the finger guide device (12), which makes it possible to compare a relevant partial image; and Figure 4B depicts a side view of the steeply forward slope (27) of the finger guide device, aligning the finger so that the relevant portion of the finger will align with the fingerprint sensor.

Figure 6A describes another preferred embodiment of a mounting pattern of a photosensitive pen, which constitutes an electrical input device for the computer, which includes the finger guide device (12) and a fingerprint sensor (16) to be mounted on the handle of a photosensitive pencil, for use with a digitizing means of handwriting as an electrical digitizing pad (33) (shown in Figure 6B) or tablet computer; and Figure 6B discloses a preferred embodiment of a photosensitive pen which constitutes an electrical input device for assembled computer, which includes the finger guide device (12) and a fingerprint sensor (16) mounted on the handle of the photosensitive pen (10). ) when used with your corresponding electrical digitizing tablet (33) to capture handwriting such as drawing, writing, or signatures for computer processing, such as image capture and storage or dynamic signature authentication in conjunction with fingerprint authentication, for a combined biometric authentication of a user. This additional preferred embodiment of the present invention utilizes a second security biometric identity verification method, to be used with fingerprint authentication. In another preferred embodiment of the present invention, the use of dynamic signature verification (DSV) combined with the finger-jamming device and the fingerprint identification or authentication system is designed to confirm that the signer authenticated with their fingerprint , has actually signed your signature, indicating a legal expression of your agreement and will, instead of writing an objection or reproducing another non-significant writing. In another preferred embodiment of the present invention, it may be desirable for the clerk to have a different emergency fingerprint, registered as an emergency indicator digit, to indicate to the system that the clerk is under duress or even illegally forced. In such a case, the system could not authenticate against the expected registered fingerprint, but would recognize the coincidence with the emergency finger designated by the clerk, which can be interpreted as the scribe's request for emergency assistance. This coincidence of the fingerprint of the emergency digit could be used to activate "silent alarms" in order to give emergency assistance to the clerk. As an alternative to reject the subject writer, the system could be programmed to appear as a failure, or communicate another reason given for the clerk's failure, in order to authenticate and simultaneously record the inability to complete the signature transaction process or otherwise delay the approval of the signature transaction, pending until the arrival of emergency assistance, such a procedure is designed to minimize the risk of harm to the subject under coercion. This additional preferred embodiment as well as the alternative modes of DSV described above, include the use of a circuit board (31) and the tip of the photosensitive pen (32) to form a subunit (30), which is in wireless communication with the electrical digitizing pad ( 33) shown in Figure 6B. This subunit is described in detail in U.S. Patent 5,576,502 and others cited herein, are considered in their entirety to be a part of the present reference. Other equivalent subunits and subsystems designed to communicate with the digitizing pointer, electrically operated and pads or tablets for handwriting capture, are known to those skilled in the art of handwriting capture devices and systems by computer. The additional mode uses a subunit manufactured by WACOM Company Limited. In this additional embodiment, the circuit board, and the photosensitive pencil subunit (30) replace the ink cartridge (24) shown in figure 1 and this replacement causes the finger guide device to enable the photosensitive pen which constitutes a device for electrical input for computer, is compatible with the digitization pads for handwriting by computer, which use this wireless method of communication between the photosensitive pencil and the pad. Figure 6A describes an exploded view of a fingerprint sensor system with finger guide device in a photosensitive pen housing. The finger guide device (12) is unfolded and the elements shown include the left and right sides steeper than the front and the rear and which are of a concave nature. The front is concave from the sensor window to the upper edge and has the shape derived from a short set of spokes to create its generally concave outline. The tip of the finger will be in contact with this front portion of the finger guide device (12). The spokes of the posterior section create the less steep concave contour and are formed to embed the portion of the finger or digit between the preferred impression and the rest of the digit adjacent to the body. The end of the finger guide device beyond the nail contains a continuation of the feedback edge, but is not designed to use the joint of the finger or the edge of the skin under the joint as a means of placing the finger adjacent to the sensor ( 16). The finger guide device (12) contains a window for the sensor (16), to reveal by itself the digit or finger of the subject. This window may be sufficient to contain a drive ring, necessary for certain types of sensors (shown) or it may cover the drive ring and replace its own electrical conductivity by that provided by a drive ring (17). In the additional preferred embodiment, this may also be the case and its performance is equivalent, aesthetics is the only significant difference. In Figure 6A, the drive ring is exposed in an equivalent manner and the finger guide device is used as a supplement for the drive ring and is conductive. Figure 6B describes the photosensitive pen writing mechanism that constitutes an electrical input device for computer in Figure 6A in radio frequency electrical communication with the electrical scanning pad (33) shown in Figure 6B, wherein the digitizing pad sends electrical signals that contain information about handwriting to a computer. You can use a photosensitive pencil for handwriting that is digitally captured and transferred to a computer, and it is preferable in this application to try to use a traditional computer mouse, because a mouse is not reasonably capable of reproducing handwriting. In addition, a photosensitive pen in this configuration can also serve as a computer pointer control device as well as a handwriting capture device, but, as noted, a mouse is limited to a pointer control device and it is not a photosensitive pen. Before or during the use of the photosensitive pencil for this purpose, the electrical signals that contain information about the fingerprint, can also be sent to the computer either through the digitizing tablet, through transmission and reception of wireless signal, through of optical data transfer, or through a separate cable in electrical communication with the computer, without substantial difference in the resulting practice and utility of the present invention.
