Abstract
Disclosed is an input device, comprising a touch sensor and a processing system. The touch sensor includes a touch sensing region and a plurality of pixels in the touch sensing region. The processing system is coupled to the touch sensor and comprises circuitry configured to: determine that a touch has occurred on a touch sensor; for each pixel included in the touch, receive touch information from the touch sensor; for each pixel included in the touch, determine a pixel response value for the pixel; and, compute a touch-based metric based on one or more pixel response values, wherein a model is used to perform behavioral authentication based on the touch-based metric.
Claims27
An input device, comprising:
- a touch sensor comprising a touch sensing region and a plurality of pixels in the touch sensing region;
- and
- a processing system coupled to the touch sensor, wherein the processing system comprises circuitry configured to:
- determine that a touch has occurred on a touch sensor;
- for each pixel included in the touch, receive touch information from the touch sensor;
- for each pixel included in the touch, determine a pixel response value for the pixel;
- and
- compute a touch-based metric based on one or more pixel response values, wherein a model is used to perform behavioral authentication based on the touch-based metric.
A touch controller for a touch sensor, the touch sensor having a touch sensing region including a plurality of pixels, wherein the touch controller comprises circuitry configured to:
- determine that a touch has occurred on the touch sensor;
- for each pixel included in the touch, receive touch information from the touch sensor;
- for each pixel included in the touch, determine a pixel response value for the pixel;
- and
- compute a touch-based metric based on one or more pixel response values, wherein a model is used to perform behavioral authentication based on the touch-based metric.
-12. (canceled)
A method for performing behavioral authentication, comprising:
- receiving, by one or more processors, touch information associated with a touch on a touch sensor included in an input device;
- computing, by the one or more processors, one or more touch-based metrics associated with the touch;
- and
- causing, by the one or more processors, a model to be executed to perform behavioral authentication based on the one or more touch-based metrics.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause a computer system to perform behavioral authentication, by performing the steps of:
- receiving touch information associated with a touch on a touch sensor included in an input device;
- computing one or more touch-based metrics associated with the touch;
- and
- causing a model to be executed to perform behavioral authentication based on the one or more touch-based metrics.
