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.

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.

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.

Abstract: Apparatus and methods are described for detecting sharing of electronic or online accounts based on grouping of data samples that include keyboard input timing factors and optionally secondary factors. The data samples can be received from various computers having various keyboards of a certain type and may be input by more than one user. The data samples are grouped based on distances and ratios of mathematical combinations of distances between input timing of key events such as dwell and flight time, as well as optionally based on at least one secondary factor related to the keyboard input timing factors. Example secondary factors include a time of day of the input; and/or a machine identification, location, and IP address of the computer used to input the sample.

Abstract: Apparatus and methods are described for pressing and releasing keys and measuring timing data of the key presses and releases of a keyboard input device to determine characteristics of different types of keyboards. A key of the keyboard may be pressed and released by a machine at measured speed; and resulting keystroke timing data may be collected from to identify timing delays and differences in delays between when the key is pressed and when the resulting timing data is collected by a computer. The timing delays and differences in delays may be used generate more accurate biometric templates and authentication inputs when a type of keyboard is used.
Abstract: A user authentication system collects measurements of physical and/or behavioral characteristics of a user. The measurements are processed by two or more processing engines to produce initial confidence measures, and a unified confidence measure is prepared from weighted inputs including the initial confidence measures.
