Dynamic signature generation from keystroke dynamics
| DWPI Title: User authentication system used for dynamic signature generation from keystroke dynamics, has processor that authenticates user of computing device based on comparison of observed signature of user with authentication signature for user |
| Abstract: Described herein are various technologies pertaining to extracting cryptographic keys from user behavioral biometrics, specifically keystroke dynamics. Such cryptographic keys can be used for, among other things, user authentication throughout computer sessions. Keystroke dynamics are timing data indicating when keys were pressed and when they were released. |
| Use: User authentication system used for dynamic signature generation from keystroke dynamics. Can be used for authenticating a user of a computing device as the user is typing on a keyboard. |
| Advantage: Provides a user authentication system that authenticates users based on behavioral biometrics such as keystroke dynamics. |
| Novelty: The system (100) includes a processor (116) that executes the instructions stored in a memory (118). The processor is configured to construct an observed signature for a user (110-114) based on a first amount of time taken by the user to complete a keystroke pattern on the keyboard of a computing device (104-108). The processor compares the observed signature for the user with an authentication signature for the user. The authentication signature is previously constructed based on a second amount of time previously taken by the user to complete the keystroke pattern. The processor authenticates the user of the computing device based on the comparison of the observed signature of the user with the authentication signature for the user, such that the computing device continues to permit the user to control the operation of the computing device. |
