Abstract

The present invention relates to an improved method of providing identification of a user or authentication of a user's identity. More particularly, the present invention relates to an improved method of providing identification of a user or authentication of a user's identity using conditional behavioural biometrics. The present invention seeks to provide an enhanced method of authenticating and/or identifying a user identity using conditional behavioural biometrics. According to a first aspect of the present invention, there is provided a method of generating a user profile for use in identifying and/or authenticating a user on a device, the device equipped with one or more sensors, the method comprising: generating a set of data points from sensory data collected by the one or more sensors; clustering the set of data points to produce a set of data clusters; developing a first classifier for the data clusters, the first classifier being operable to assign a further data point derived from a further user interaction with the computing device to one of the data clusters; and developing one or more further classifiers for at least one of the data clusters, the further classifier operable to identify and/or authenticate a user identity based on the further data point.

Dependent claims

A method comprising:

(a) monitoring touch-screen gestures of a user, that interacts with an online service via a touch-screen of a computing device;
and monitoring acceleration and tilt of said computing device, during said touch-screen gestures;
(b) extracting data-points from information monitored in step (a);
(c) generating a user-specific profile that indicates a characterizing acceleration and a characterizing tilt of the computing device during said touch-screen gestures;
(d) subsequently, monitoring touch-screen gestures during access to said online service, and monitoring accompanying acceleration and tilt;
(e) extracting data-points from information monitored in step (d);
(f) analyzing the data-points extracted in step (e), and checking whether said data-points match said user-specific profile generated in step (c);
(g) if the checking of step (f) has a negative result, then:
generating a notification that a user that interacted in step (d) to access said online service, is different from the user that interacted in step (a) to access said online service;
wherein the generating of step (g) is further based on:
determining that a first characteristic of landscape/portrait device orientation during touch-screen gestures monitored on the computing device in step (a), is different from a second characteristic of landscape/portrait device orientation during touch-screen gestures monitored on the computing device in step (d).
