US 11,308,187 B2 · User authentication

Abstract

Examples associated with user authentication are described. One example system includes a set of authentication modules. A data store stores data describing disruption ratings of members of the set of authentication modules. A user confidence module maintains a confidence rating that a current user of a device is an authenticated user of the device. The confidence module controls execution of the authentication modules based on the confidence rating and on the disruption ratings of the authentication modules. The user confidence module controls execution of relatively less disruptive authentication modules when the user confidence module is confident that the current user of the device is the authenticated user of the device. The user confidence module maintains the confidence rating based on feedback received from authentication modules.

Dependent claims

A system comprising:

a plurality of authentication modules;
a data store to store disruption ratings and resource consumption ratings of respective authentication modules of the plurality of authentication modules, wherein the resource consumption ratings comprise a first resource consumption rating indicating a first resource consumption of a resource of a device by a first authentication module of the plurality of authentication modules, and a second resource consumption rating indicating a different second resource consumption of the resource of the device by a different second authentication module of the plurality of authentication modules;
a processor;
and
a non-transitory storage medium storing instructions executable on the processor to:
maintain a confidence rating that a current user of the device is an authenticated user of the device, and
in response to the confidence rating, select an authentication module from among the plurality of authentication modules based on the disruption ratings and the resource consumption ratings of the respective authentication modules.

4 more elements

A method comprising:

setting, by a device, a confidence rating related to whether a current user of the device is an authenticated user;
accessing, by the device, resource consumption ratings of respective authentication techniques of a plurality of authentication techniques, wherein the resource consumption ratings comprise a first resource consumption rating indicating a first resource consumption of a resource of the device by a first authentication technique of the plurality of authentication techniques, and a second resource consumption rating indicating a different second resource consumption of the resource of the device by a different second authentication technique of the plurality of authentication techniques;
selecting, by the device, from the plurality of authentication techniques, a selected authentication technique for determining whether the current user of the device is the authenticated user of the device, where the selecting is based on comparing the resource consumption ratings of the respective authentication techniques;
executing, by the device, the selected authentication technique;
and
updating, by the device, the confidence rating based on a result received from the selected authentication technique that indicates a likelihood that the current user is the authenticated user.

3 more elements

A non-transitory computer-readable medium storing processor executable instructions that when executed cause a system to:

set a confidence rating related to whether a current user of a device is an authenticated user;
access disruption ratings and resource consumption ratings of respective authentication techniques of a plurality of authentication techniques, wherein the resource consumption ratings comprise a first resource consumption rating indicating a first resource consumption of a resource of the device by a first authentication technique of the plurality of authentication techniques, and a second resource consumption rating indicating a different second resource consumption of the resource of the device by a different second authentication technique of the plurality of authentication techniques;
in response to the confidence rating, select an authentication technique from the plurality of authentication techniques, wherein the selecting comprises:
in response to the confidence rating being at a first level, selecting the first authentication technique based on a first disruption rating and the first resource consumption rating of the first authentication technique, wherein the first disruption rating indicates that the first authentication technique is less disruptive than the second authentication technique, and the first resource consumption rating indicates that the first authentication technique consumes less of the resource than the second authentication technique, and
in response to the confidence rating being at a second level lower than the first level, selecting the second authentication technique based on a second disruption rating and the second resource consumption rating of the second authentication technique;
and
update the confidence rating based on a result received from the first selected authentication technique.
