Abstract
A user's emotion can be determined based on pupil dilation response to a challenge prompt. In response to an authentication request, a registered challenge prompt and an expected pupil dilation response can be retrieved. The challenge prompt can include one or more images or a video designed to cause a pupil dilation response in a user. The challenge prompt is displayed to the user and the user's pupil dilation response is captured. At least one user action of the user is monitored and an emotion is determined based on the at least one user action. The emotion is associated with the pupil dilation response.
Claims18
A method, comprising:
- conveying, for display on a display device, a challenge prompt to a first user, wherein the challenge prompt comprises one or more images that cause a first pupil dilation response;
- capturing the first pupil dilation response of the first user;
- monitoring at least one user action of the first user;
- determining an emotion based on the at least one user action;
- associating the emotion with the first pupil dilation response;
- comparing the first pupil dilation response to an expected pupil dilation response;
- and
- authenticating the first user when the first pupil dilation response matches the expected pupil dilation response within a predetermined threshold.
A system, comprising:
- a processor coupled to a memory that stores instructions that when executed by the processor cause the processor to:
- convey, for display on a display device, a challenge prompt to a first user, wherein the challenge prompt comprises one or more images that cause a first pupil dilation response;
- capture the first pupil dilation response of the first user;
- monitor at least one user action of the first user;
- determine an emotion based on the at least one user action;
- associate the emotion with the first pupil dilation response;
- compare the first pupil dilation response to an expected pupil dilation response;
- and
- authenticate the first user when the first pupil dilation response matches the expected pupil dilation response within a predetermined threshold.
A method, comprising:
- executing, on a processor, instructions that cause the processor to perform operations comprising:
- identifying a challenge prompt for a first user, wherein the challenge prompt comprises one or more images that cause a first pupil dilation response;
- conveying, for display on a display device, the challenge prompt to the first user;
- capturing the first pupil dilation response of the first user;
- monitoring at least one user action of the first user;
- determining an emotion based on the at least one user action;
- associating the emotion with the first pupil dilation response;
- comparing the first pupil dilation response to an expected pupil dilation response;
- and
- authenticating the first user when the first pupil dilation response matches the expected pupil dilation response within a predetermined threshold.
