Abstract

Method and system for authenticating a session on a communication device. One method includes determining a use context of the communication device and an authentication status of the communication device. The method further includes determining a predetermined period of time based on at least one of the use context and the authentication status. The method further includes generating biometric templates based on at least one of the use context and the authentication status. The method further includes selecting a matching threshold for the biometric templates based on at least one of the use context and the authentication status. The method further includes comparing a match score of each of the biometric templates to the matching threshold to determine a passing amount of biometric templates with match scores that meet or exceed the matching threshold. The method further includes authenticating the session on the communication device.

Dependent claims

A method of authenticating a session on a communication device, the method comprising:

determining, via an electronic processor, a use context of the communication device;
determining, via the electronic processor, an authentication status of the communication device based on whether the session on the communication device is authenticated;
determining, via the electronic processor, a predetermined period of time based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
generating biometric templates, via a biometric sensor, based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
selecting, via the electronic processor, a matching threshold based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
comparing, via the electronic processor, a match score of each of the biometric templates to the matching threshold to determine a passing amount of biometric templates with match scores that meet or exceed the matching threshold;
and
authenticating the session on the communication device, via the electronic processor.

a biometric sensor configured to generate biometric templates;
and
an electronic processor configured to
determine the use context of the communication device based on signals received from the context sensor;
determine an authentication status of the communication device based on whether a session on the communication device is authenticated;
determine a predetermined period of time based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
instruct the biometric sensor to generate biometric templates based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
select a matching threshold for the biometric templates based on at least one of the group consisting of the use context of the communication device and the authentication status of the communication device;
compare a match score of each of the biometric templates to the matching threshold to determine a passing amount of biometric templates with match scores that meet or exceed the matching threshold;
and
authenticate the session on the communication device.
