Finger guide device
First Claim
1. A method for enabling the identification or authentication of a person comprising:
- in an enrollment step, scanning several overlapping portions of a finger of the person and electronically assembling the overlapping portions into a completed template representing an area of the person'"'"'s fingerprint that is larger than any single scanned portion,in an identification or authentication step, having a fingerprint scanner located within a finger guide device that has side surfaces that form a recess for receiving a finger, the recess having a short concave radius at front end of the finger guide device where a fingertip just below a finger nail of the finger is proximal to the front end, and having a longer concave radius, relative to short concave radius, at the back end adjacent to the opposite side of a sensor forming a guide that extends up the finger towards the body of the person, slidingly guiding, using the guide of the recess, the finger downwardly along the side surfaces until reaching a stable position of global minimum over the fingerprint scanner to obtain a scan of a portion of the fingerprint, wherein by guiding the finger in the finger guide device, the finger touches the sensor consistently in a same approximate place so that a relevant portion of the fingerprint is read by the sensor for comparison of the scanned portion obtained with the completed template, andif the scanned portion is found within the completed template, identifying or authenticating the person.

Abstract
A finger guide device that positions a finger (or minutiae containing digit) of a human subject on a fingerprint sensor in a manner optimal for the data capture operation of authentication or identification of said subject wherein a relevant portion of the finger is in alignment with a sensor or scanner. The finger guide device may also be used for enrollment of the initial fingerprint data into the system. The device may contain an outer surface ridge which feels somewhat uncomfortable due to application of a high pressure per square inch on small areas of the finger when the finger is incorrectly positioned to encourage correct placement of the finger. The finger guide device may have a curved inside surface to contour to a wide variety of fingertip shapes and sizes, wherein the sides and front have shorter radii of curvature than the rearward portion of the finger guide device.

1. A method for enabling the identification or authentication of a person comprising:
-
in an enrollment step, scanning several overlapping portions of a finger of the person and electronically assembling the overlapping portions into a completed template representing an area of the person'"'"'s fingerprint that is larger than any single scanned portion, in an identification or authentication step, having a fingerprint scanner located within a finger guide device that has side surfaces that form a recess for receiving a finger, the recess having a short concave radius at front end of the finger guide device where a fingertip just below a finger nail of the finger is proximal to the front end, and having a longer concave radius, relative to short concave radius, at the back end adjacent to the opposite side of a sensor forming a guide that extends up the finger towards the body of the person, slidingly guiding, using the guide of the recess, the finger downwardly along the side surfaces until reaching a stable position of global minimum over the fingerprint scanner to obtain a scan of a portion of the fingerprint, wherein by guiding the finger in the finger guide device, the finger touches the sensor consistently in a same approximate place so that a relevant portion of the fingerprint is read by the sensor for comparison of the scanned portion obtained with the completed template, and if the scanned portion is found within the completed template, identifying or authenticating the person. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

2. A method for identification or authentication of a person who in an enrollment step has had several overlapping portions of a finger scanned and electronically assembled into a completed template representing an area of the person'"'"'s fingerprint that is larger than any single scanned portion, comprising
in an identification or authentication step, having a fingerprint scanner located within a finger guide device that has side surfaces that form a recess for receiving a finger, the recess having a short concave radius at front end of the finger guide device where a fingertip just below a finger nail of the finger is proximal to the front end, and having a longer concave radius, relative to short concave radius, at the back end adjacent to the opposite side of a sensor forming a guide that extends up the finger towards the body of the person, slidingly guiding, using the guide of the recess, the finger downwardly along the side surfaces until reaching a stable position of global minimum over the fingerprint scanner to obtain a scan of a portion of the fingerprint, wherein by guiding the finger in the finger guide device, the finger touches the sensor consistently in a same approximate place so that a relevant portion of the fingerprint is read by the sensor for comparison of the scanned portion obtained with the completed template, and if the scanned portion is found within the template, identifying or authenticating the person.

3. A method for enabling the identification or authentication of a person comprising
providing a fingerprint scanner located within a finger guide device that has side surfaces that form a recess for receiving a finger, the recess having a short concave radius at front end of the finger guide device where a fingertip just below a finger nail of the finger is proximal to the front end, and having a longer concave radius, relative to short concave radius, at the back end adjacent to the opposite side of a sensor forming a guide that extends up the finger towards the body of the person, slidingly guiding, using the guide of the recess, a finger downwardly along the side surfaces of the finger guide device until reaching a stable position of global minimum over the fingerprint scanner to enroll the person by scanning several overlapping portions of the finger of the person and electronically assembling the overlapping portions into a completed template representing an area of the person'"'"'s fingerprint that is larger than any single scanned portion, so that later the person can guide his or her scanned finger over a fingerprint scanner to obtain a scan of a portion of the fingerprint by guiding the person'"'"'s finger in the finger guide device in a same approximate place when the person'"'"'s finger is placed in the finger guide device so that a relevant portion of the fingerprint is read by the sensor for comparison of the scanned portion with the completed template.
