Continuous authentication confidence module
First Claim
1. A user device comprising:
- processor circuitry configured to determine presence data;
a confidence factor comprising at least one of a sensor configured to capture sensor input and a system monitoring module configured to monitor operation of the user device and to collect monitor data related to the monitoring;
memory configured to store a confidence score and an operating system; and
a continuous authentication confidence module (CACM) configured to;
determine the confidence score in response to an initial authentication of a specific user;
update the confidence score based, at least in part, on at least one of an expectation of user presence and selected presence data; and
notify at least one of the operating system and a remote communication partner that the authentication is no longer valid if the updated confidence score is within a tolerance of a session close threshold;
wherein;
the initial authentication configured to open a session, the confidence score configured to indicate a current strength of authentication at a point in time during the session;
when the confidence score is at or above a confidence score power threshold, the CACM is configured to choose a type of said selected presence data based, at least in part, on a power consumption associated with obtaining said chosen type of said selected presence data; and
determine a confidence value based, at least in part, on the chosen type of selected presence data; and
adjust the confidence score based, at least in part, on the confidence value.

Abstract
Generally, this disclosure describes a continuous authentication confidence module. A system may include user device including processor circuitry configured to determine presence data; a confidence factor including at least one of a sensor configured to capture sensor input and a system monitoring module configured to monitor activity of the user device; memory configured to store a confidence score and an operating system; and a continuous authentication confidence module configured to determine the confidence score in response to an initial authentication of a specific user, update the confidence score based, at least in part, an expectation of user presence and/or selected presence data, and notify the operating system that the authentication is no longer valid if the updated confidence score is within a tolerance of a session close threshold; the initial authentication configured to open a session, the confidence score configured to indicate a current strength of authentication during the session.

7. A method comprising:
-
determining a confidence score in response to an initial authentication of a specific user to a user device, the initial authentication configured to open a session, the confidence score configured to indicate a current strength of authentication at a point in time during the session; updating the confidence score based, at least in part, on at least one of an expectation of user presence and selected presence data; and notifying at least one of the user device and a remote communication partner that the authentication is no longer valid if the updated confidence score is within a tolerance of a session close threshold; said updating comprises, when the confidence score is at or above a confidence score power threshold, choosing a type of selected presence data based at least in part on a power consumption associated with obtaining said chosen type of said presence data; determining a confidence value based at least in part on the chosen type of selected presence data; and adjusting the confidence score based at least in part on the confidence value. - View Dependent Claims (8, 9, 10, 11)

12. A system comprising one or more storage mediums having stored thereon, individually or in combination, instructions that when executed by one or more processors result in the following operations comprising:
-
determining a confidence score in response to an initial authentication of a specific user to a user device, the initial authentication configured to open a session, the confidence score configured to indicate a current strength of authentication at a point in time during the session; updating the confidence score based, at least in part, on at least one of an expectation of user presence and selected presence data, said updating comprising, when the confidence score is at or above a confidence score power threshold, choosing a type of selected presence data based at least in part on a power consumption associated with obtaining said chosen type of said presence data; notifying at least one of the user device and a remote communication partner that the authentication is no longer valid if the updated confidence score is within a tolerance of a session close threshold; determining a confidence value based at least in part on the chosen type of selected presence data; and adjusting the confidence score based at least in part on the confidence value. - View Dependent Claims (13, 14, 15, 16)
