Performing authentication
Preference data is received. The received preference data is compared to stored preference data associated with a user with which the received preference data is associated. A determination is made whether to authorize an action based at least on the comparison. The preference data is received as a selection.
1. An authentication system, comprising:
an interface configured to receive, in response to a request presented to a first user, preference data; and
a processor configured to:
compare the received preference data to stored preference data associated with an enrolled user, wherein the stored preference data was captured in conjunction with a previous request for preference data presented to the enrolled user, wherein the stored preference data includes an indication of a type of preference with respect to an item associated with the previous request, wherein the indicated type of preference corresponds to one of a positive preference, a negative preference, and a neutral preference for the item; and
determine that an action should be authorized based at least in part by computing a score based at least in part on the comparison and determining whether the score exceeds a threshold.
2. The system of claim 1 wherein the action includes a password reset request.
3. The system of claim 1 wherein the action includes receiving access to a service.
4. The system of claim 1 wherein the interface includes a graphical user interface.
5. The system of claim 1 wherein the interface is configured to receive at least some of the received preference data acoustically.
6. The system of claim 1 wherein the received data and stored data are of different types.
7. The system of claim 1 wherein the threshold is determined based at least in part on an entropy score.
8. The system of claim 1 further comprising an enrollment interface configured to capture at least a portion of the stored preference data.
9. The system of claim 8 wherein the enrollment interface is configured to display a plurality of categories.
10. The system of claim 8 wherein the enrollment interface is configured to receive a selection of a category and in response display an item associated with the category.
11. The system of claim 10 wherein at least one preference captured by the enrollment interface is a preference for the item.
12. The system of claim 8 wherein the enrollment interface is further configured to provide an audio sample.
13. The system of claim 1 wherein the received preference data includes a preference for at least one of a food, an activity, a television show, and a style of music.
14. The system of claim 1 wherein the received preference data includes a negative preference.
15. The system of claim 1 wherein the received preference data includes a neutral preference.
16. A method, comprising:
receiving, in response to a request presented to a first user, preference data;
comparing the received preference data to stored preference data associated with an enrolled user, wherein the stored preference data was captured in conjunction with a previous request for preference data presented to the enrolled user, wherein the stored preference data includes an indication of a type of preference with respect to an item associated with the previous request, wherein the indicated type of preference corresponds to one of a positive preference, a negative preference, and a neutral preference for the item; and
determining, by a microprocessor, that an action should be authorized based at least in part by computing a score based at least in part on the comparison and determining whether the score exceeds a threshold;
wherein the preference data is received as a selection.
17. The method of claim 16 wherein the action includes a password reset request.
18. The method of claim 16 further comprising capturing preference data during an enrollment.
19. A computer program product embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
receiving, in response to a request presented to a first user, preference data;
comparing the received preference data to stored preference data associated with an enrolled user, wherein the stored preference data was captured in conjunction with a previous request for preference data presented to the enrolled user, wherein the stored preference data includes an indication of a type of preference with respect to an item associated with the previous request, wherein the indicated type of preference corresponds to one of a positive preference, a negative preference, and a neutral preference for the item; and
determining that an action should be authorized based at least in part by computing a score based at least in part on the comparison and determining whether the score exceeds a threshold;
wherein the preference data is received as a selection.
20. The system of claim 1 wherein the interface is further configured to present the user with a set of candidate items and wherein the user is asked to perform at least one of the following actions with respect to at least some of the candidate items: make a selection; make a classification; or make a combination thereof.
