  • Publication number: 20110082791
    Abstract: A request for a secure financial transaction is received from a user, who is authenticated with a biometric device. If the user is authenticated, an authentication token is received from the biometric device and sent to a remote device, which initiates the secure financial transaction. Upon initiation of the secure financial transaction, details related to the secure financial transaction are displayed to the user and the those details are monitored until the secure financial transaction is completed.

  • Publication number: 20110083018
    Abstract: Biometric information is authenticated by a web-enabled application that identifies a biometric sensor installed in a client device. The authentication procedure reads biometric information associated with a user and compares the biometric information with a biometric template associated with that user. If the biometric information matches the biometric template, the authentication procedure retrieves credentials associated with the user and communicates those credentials to a requesting process.

  • Publication number: 20110083016
    Abstract: An apparatus includes a biometric sensor capable of identifying biometric information associated with a user. A storage device coupled to the biometric sensor stores user information. A biometric service is coupled to the biometric sensor and capable of communicating with the biometric sensor. A web browser application having a biometric extension communicates with the biometric sensor via the biometric service. The web browser's biometric extension is capable of communicating with multiple web servers.

  • Publication number: 20110082800
    Abstract: A user request to implement a secure transaction is received and communicated to a web server. Transaction details signed with a secret key are received from the web server and displayed to the user. The user is requested to confirm the secure transaction by providing biometric data. If the user's biometric data is validated, an authentication token is received from a biometric device and the authentication token is communicated to the web server. The web server processes the secure transaction if the authentication token is confirmed as a valid authentication token.

  • Publication number: 20090154779
    Abstract: A method and device for removing common artifacts, such as stiction, from fingerprint scans created by partial fingerprint scanners. The partial fingerprint scanner data is assessed to determine if successive partial fingerprint images are overly similar to each other, which can occur during stiction. If this similarity exceeds a preset threshold, then at least some of the overly similar partial images will be removed (redacted) from the overall image dataset. The complete overall image is generated from the redacted data set. This method is particularly useful for creating “intelligent” low-cost, low power partial fingerprint scanners and scanner driver chips that can pre-process the partial fingerprint data that is generated during the course of a finger swipe, and remove stiction artifacts on a real-time or near-real time basis using relatively simple and low power on-chip processing circuits, and then send the corrected data to more sophisticated processors for subsequent fingerprint analysis.
