  • Incorporating false reject data into a template for user authentication
    Patent number: 8533486
    Abstract: Access to a resource may be denied in response to a score value being below a threshold value. The score value may be based on timing information of key-press and key-release events. After denying access to the resource, the timing information of key-press and key-release events may be incorporated into the keystroke dynamics template.

  • False reject mitigation using non-biometric authentication
    Patent number: 8533815
    Abstract: Providing secondary non-biometric authentication to identify a user following a failure of a biometric authentication based on a biometric template. In one embodiment, a knowledge-based authentication scheme may be provided. In another embodiment, a one-time password authentication scheme may be provided. An identity of the user may be confirmed using the non-biometric based authentication scheme.

  • Keystroke dynamics authentication techniques
    Patent number: 8332932
    Abstract: A keystroke dynamics authentication system collects measurements as a user types a phrase on a keyboard. A first set of derived data values are computed based on the collected measurements, and then a second set of derived data values are computed based on the first set of derived values. The first and second sets of derived values are used to construct a template for identifying the user based on his typing.

  • Method and Apparatus for Visualizing and Analyzing Unit Pricing for Digital Product Purchases to Determine Revenue Optimization Opportunities for Service Provider
    Publication number: 20120259794
    Abstract: Customers who purchase a digital service under a subscription-like payment model are grouped according the value each receives, which is computed from stored transaction data as the amount the customer pays divided by the benefit the customer receives. Customers who pay more or less than a mid-range “normal” price may be given price adjustments to bring the value they receive closer to the normal price.
