A formation of a rule module customized to the user in a rule module clearinghouse, wherein at least one pattern data of a user is associated with at least one execution command of the user. A user identification step, wherein the electronic identicator compares a bid biometric sample taken directly from the person of the user with at least one previously registered biometric sample for producing either a successful or failed identification of the user.Type: GrantFiled: August 4, 2005Date of Patent: October 20, 2009Assignee: YT Acquisition CorporationInventors: Ned Hoffman, Philip Dean Lapsley

Patent number: 7599532Abstract: A finger sensor may include a finger sensing integrated circuit (IC) having a finger sensing area, an IC carrier having a cavity receiving the finger sensing IC therein and having at least one beveled upper edge, and a frame surrounding at least a portion of an upper perimeter of the IC carrier and having at least one inclined surface corresponding to the at least one beveled upper edge of the IC carrier. The finger sensor may also include a biasing member for biasing the IC carrier into alignment within the frame. The biasing member may include at least one resilient body for biasing the IC carrier upward within the frame. In other embodiments, the finger sensor may include an IC carrier having a cavity receiving the finger sensing IC therein and having at least one laterally extending projection.Type: GrantFiled: September 8, 2008Date of Patent: October 6, 2009Assignee: Authentec, Inc.Inventors: Dale R.

Publication number: 20090226054Abstract: An acquisition system for obtaining images of a fingerprint from a finger, or marks of another kind of target. The system may have two or more cameras positioned at different directions towards the target. Each camera may have a light source for illuminating the target from a direction different than that of the respective camera. The cameras may take sequences of images of the target at different focuses as the whole target might not be in focus in one image due to a depth of focus being less than the depth of the target. Portions of the images showing the target in focus may be cut from the images and stitched together to result in an image revealing virtually the whole target in focus. This target may be a fingerprint to be rolled out on or in a two dimensional medium for analysis, identification, storage, and so on.Type: ApplicationFiled: March 5, 2008Publication date: September 10, 2009Applicant: HONEYWELL INTERNATIONAL INC.Inventor: Jan Jelinek

Patent number: 7574023Abstract: A fingerprint image pickup device includes a light source that emits a light for transmission through a fingertip portion having a fingerprint to be photographed, an image pickup unit that picks up the light from the light source and transmitted through the subject to acquire a fingerprint image in which convex and concave parts of the fingerprint are dark and bright, respectively, and an optical system that images the light transmitted through the fingertip portion on the image pickup unit. The optical system is arranged so that a distal side of the fingertip portion is tilted, at a predetermined angle, farther away from the optical system than an opposite side, with reference to a position at which a ventral side of the fingertip portion contacts a face orthogonal to an optical axis of the optical system.Type: GrantFiled: September 30, 2005Date of Patent: August 11, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Emiko Sano, Masahiro Shikai, Akihide Shiratsuki, Toshiro Nakashima, Takahiro Nakamura

Patent number: 7565329Abstract: Tokenless biometric authorization of transaction between a consumer and a merchant uses an identicator and an access device. A consumer registers with the identicator a biometric sample taken from the consumer. The consumer and merchant establish communications via the access device. The merchant proposes a transaction to the consumer via the access device. The access device communicates to the merchant associated with the access device. After the consumer and merchant have agreed on the transaction, the consumer and the identicator use the access device to establish communications. The access device communicates to the identicator the code associated with the access device. The identicator compares biometric sample from the consumer with registered biometric sample. Upon successful identification, the identicator forwards information regarding the consumer to the merchant.Type: GrantFiled: May 30, 2001Date of Patent: July 21, 2009Assignee: YT Acquisition CorporationInventors: Philip D. Lapsley, Philip J. Gioia, Michael Kleeman

Patent number: 7565548Abstract: Quality of biometric prints is enhanced by any one of several different methods. In one embodiment, if a biometric print does not have a high enough quality, the biometric print is discarded. In another embodiment, a matching score is associated with the degree to which the two biometric prints match. In another embodiment, a ranking is associated with a biometric print, and the ranking is determined based upon two or more matching scores associated with the biometric print. In another embodiment, a variety of distinguishing features are derived from a given biometric print and are stored for authenticating a biometric print of a user requesting access to a secure entity. In an embodiment, a transformation is applied to at least a portion of a newly acquired biometric print to improve the match of the newly acquired biometric print to a stored biometric print.Type: GrantFiled: November 17, 2005Date of Patent: July 21, 2009Assignee: Biogy, Inc.Inventors: Michael S.
