Definitions

  • a reliable method of checking the identification of an individual is to measure the dimensions of a human hand and particularly the lengths of the various fingers. For instance, when it is desired to know whether an individual who presents a credit card is the proper holder of the credit card, one can compare the lengths of the fingers with stored data to determine with a high degree of accuracy whether the person presenting the card is the one to whom the card was issued.
  • an improved apparatus of the finger or hand identification type wherein the entire apparatus is included within a member on which a hand can be placed.
  • a flat plate which occupies little counter space and which has a relatively low power consumption is employed. Further, all significant optical features along the length of the finger and the webbing between fingers can be measured and some or all used in the determination of valid identity. Also because of the optical geometry of the measuring device, the measurement is free from artifact due to fingernails.
  • an object of the present invention to provide an identification apparatus of the type wherein one determines the characteristics of one or more fingers which does not require an overhead light source and which measures a plurality of characteristics of the hand or fingers.
  • an identification system which includes a hand plate 10 mounted on a base 12.
  • a card reader 14 is connected by a suitable cable 16 to the identification device.
  • the hand plate 10 has a plurality of slots therein and, in the embodiment illus - trated, has slots for four fingers designated 18, 20, 22 and 24 which are splayed as in a normal hand.
  • two slots are provided designated 26 and 28, the purpose of which is to identify the crotch positions between the fingers placed between slots on 18 and 20 as well as between slots 22 and 24, respectively.
  • the hand plate also has a locating pin 30 to insure that one places the hand in the proper position on the identification device.
  • the hand plate is hollowed around each of the finger slots as is shown at 32; ordinarily the crotch slots are not so hollowed. This hollowing of the finger slots makes it simpler to place the hand in the proper position and also secures better contact between the finger and the hand plate.
  • both the light source and the light sensing device are incorporated in a cell located under the hand plate 10.
  • the cells move up and down on the finger slots and the crotch slots to measure the desired characteristics of the fingers.
  • One of the cells is shown enlarged in Fig. 7.
  • the cell is generally designated 34 and has a round body portion 36 with opposed flat sides 38.
  • the flat sides 38 form a sliding fit in one of the longitudinal slots.
  • the cell also has flat sides 39 at right angles to the flat sides 38 which fit into a transverse slot as at 20B in figures 6 and 7.
  • Each of the cells contains a light source such as a LED 40 and a photoelectric pick up cell 42.
  • each of the units 34 is self contained with its light source and pick up so that if there is light colored object, such as a finger in the slot, light will be reflected back from the light source to the pick up cell 42.
  • the path of travel of the cells 34 is up and down the path of the extended fingers. Since the fingers are spread out in a normal hand it is necessary that the path of the cells have both a longitudinal and a transverse component.
  • a longitudinal guide plate 44 which has a plurality of slots therein corresponding to the slots in the hand plate.
  • slot 18A in the longitudinal guide plate corresponds to slot 18 in the hand plate and so on.
  • the movable transverse guide plate 46 which is mounted for longitudinal movement on the rods 48 and 50.
  • This plate has a series of short slots corresponding with the slots in the longitudinal guide plate except that these slots are at right angles to the slots in the longitudinal guide plate.
  • slot 18B is lo cated at a right angle to slot 18A and so on.
  • plate 46 has a transverse slot 52 extending for almost the complete width of the plate.
  • transverse drive plate 46 a motor 54 with a gear box 56 mounted thereon with an output shaft 58.
  • Shaft 58 is coupled to a crank arm 60 provided with a roller 62 which fits into slot 52.
  • the motion imparted can best be appreciated with reference to Fig's. 3 and 5.
  • the drive plate 46 moves up and down on rods 48 and 50 in the direction shown by the double arrow 64. This will cause cells 34 to move in a transverse direction and at the same time in a longitudinal direction; the interaction of the two sets of slots produces a vector upon each of the cells so that as the shaft 58 makes one revolution, each of the cells will follow an angling path up and down one of the finger slots.
  • the device work on infrared light to reduce the effect of ambient light on the operation. Accordingly, the strips 66 which are transparent to infrared light and opaque to visible light would normally be placed under each of the slots of the hand plate 10.
  • the drive plate 46 also carries a transparent grid blade 68 which has a series of dark lines 70 thereon.
  • the grid plate 68 passes between the arms 71 and 72 of an optical sensor which can be of substantially the same structure as the device 34 so that as the grid 68 passes over the pick up.72, a series of pulses will be produced to serve as a clock to indicate the position of the drive plate.
  • Optically significant features are determined by a measurement of optical reflectance along the finger. Such features include: the position of maximum reflectance points, minimum reflectance points, and points half-way in reflectance between maximum and minimum points. The position of the maximum, minimum and midpoints of the spacial lst, 2nd, 3rd---Nth derivatives of the reflectance signal can serve as reference points.
  • Figs. 11, 12, 13 and 14 show scans of typical fingers. It will be seen that the maximum value of reflected light does not reach a sharp peak so that the maximum value is not a suitable reference point. However by measuring the minimum reflectance point as well as the maximum and taking a value half-way between these points, one obtains a valid and reproducible reference point.
  • FIG. 15 Another method of securing significant measurements is illustrated in Figs. 14, 15 and l6.
  • Fig. 15 the first derivative (dV) of the curve of Fig. 14 is plot-(dt) ted so that one obtains a plurality of peaks such as those designated 43A, 43B and 43C which can be compared with stored data.
  • Higher derivations provide even more sharply defined points.
  • the first, second or higher derivatives of the response curves one can convert subtle, almost imperceptible changes into sharply defined points.
  • Fig. 8 there is shown a highly simplified diagram of the detection system and it will be seen that the light falling on the sensors 42A, 42B, 42C, 42D, 4 2 E and 42F (representing four fingers and two crotches of a hand) is fed to an analog signal multiplexer 83 whose inputs are connected to each of the photo detector circuits; this signal is fed to an analog to digital converter 84 connected to the output of the analog multiplexer, and then to a microprocessor 85 which controls the multiplexer and receives the output of the analog to digital converter.
  • a grid clock 87 develops a position signal which is fed to the microprocessor 85.
  • a magnetic card reader 14 which is connected to the microprocessor stores and provides the reference hand geometry data. In this manner, one or more characteristics such as the length of the finger are determined and is compared with data included on the card, or supplied from a separate source.
  • the light source and photosensor be mounted as a unit in a cell which scans a portion of the hand.
  • a fixed light source as is shown in Fig. 10.
  • a fixed light source 95 is employed which illuminates the end and a portion of the under surface of a finger and the moving cell 97 contains only the photosensor.
