METHOD AND APPARATUS FOR CONTINUOUS AND IMPLICIT LOCAL AUTHENTICATION OF WIRELESS MOBILE USERS BASED ON DYNAMIC PROFILING OF CONDUCT PATTERNS

摘要

The invention provides methods and apparatus for local, continuous and implicit authentication of wireless communication device users. The implicit authentication method is devised to constantly and transparently monitor the user behaviour and match it against a previously learnt model. The monitoring and matching operations are performed locally in a Trusted Execution Environment inside the device and thus all the sensitive data remains always under the control of the user and isolated from other applications. When the implicit authentication method considers that the device is being used by a non-legitimate user, it asks for an explicit, biometric-based authentication mechanism.
