USER AUTHENTICATION METHOD FOR ACCESS TO A MOBILE USER TERMINAL AND CORRESPONDING MOBILE USER TERMINAL
First Claim
1. A user authentication method for access to a mobile user terminal, said mobile terminal including one or more movement sensor supplying information on movements of said mobile terminal, said method comprising:
- authenticating a user on the basis of a movement performed handling said mobile terminal;
acquiring in a measuring phase a test pattern (tx) of values sensed by one or more movement sensor related to a movement performed in a predetermined condition corresponding to an action for operating said mobile terminal;
comparing in a biometric recognition phase said acquired test pattern to a stored pattern of values obtained from said one or more movement sensor by a training phase executed by an accepted user performing said action for operating said mobile terminal;
said comparing including measuring a similarity of said acquired test pattern to said stored pattern; and
obtaining an authentication result by comparing said measured similarity to a threshold.

Abstract
A user authentication method for access to a mobile user terminal including one or more movement sensor supplying information on movements of the mobile terminal, includes authenticating a user on the basis of a movement performed handling the mobile terminal. A test pattern of values is sensed by one or more movement sensor related to a movement performed in a predetermined condition corresponding to an action for operating the mobile terminal. In a biometric recognition phase the acquired test pattern is compared to a stored pattern of values obtained from the one or more movement sensor by a training phase executed by an accepted user performing the action for operating the mobile terminal. The comparison includes measuring a similarity of the acquired test pattern to stored pattern. An authentication result is obtained by comparing the measured similarity to a threshold.
