Abstract:
A system for implicit authentication for a mobile device associated with a user, wherein the implicit authentication is behavioural, biometric and task-based and includes at least one authentication task selected so as to leverage the user's muscle memory. The mobile device comprises a touchscreen; a transaction authentication information unit; one or more sensors coupled to the transaction authentication information unit; and an anomaly detector coupled to the transaction authentication information unit. The sensors comprise one or more touchscreen sensors coupled to the touchscreen, an accelerometer, and a gyroscope, and are used to obtain and transmit one or more sets of data to the transaction authentication information unit. The sets of data are associated with one or more performances of the authentication task by the user. The anomaly detector generates an authentication model using the one or more data sets transmitted to the transaction authentication information unit.

Claim (Index 42):
A method of authenticating a user on a mobile device, the method comprising:\n displaying first prompts on a display of the mobile device, the first prompts instructing a user in a first performance of a task, the task comprising a performance of an activity dependent on muscle memory; recording first sensor data obtained from a plurality of sensors incorporated within the mobile device, the sensor data obtained during the first performance; processing the first sensor data to determine first parameters of a predetermined model of the activity and storing the first parameters in a user model associated with the activity and the user, the user model being stored in a database within the mobile device; displaying second prompts on the display, the second prompts instructing the user in a second performance of the task; recording second sensor data obtained during the second performance; comparing the second sensor data to the user model to generate an authentication decision; and processing the second sensor data to determine second parameters of the predetermined model of the activity and storing the second parameters in the user model associated with the activity and the user, the second parameters updating the user model.
