1. A method, comprising:
- receiving random subject matter sent from an authentication server to a client device for authentication of a user;
prompting the user to draw the random subject matter at the client device as a first attempt to authenticate the user;
receiving data describing a sketch of the random subject matter drawn by the user;
sending the data to the authentication server for comparison to a freehand model describing sketching skills of the user;
receiving a denial of the authentication indicating the data describing the sketch of the random subject matter failed to match the freehand model;
sending another random subject matter with the denial of the authentication; and
prompting the user to draw the another random subject matter as a second attempt to authenticate the user.

Abstract
Methods, systems, and products authenticate users for access to devices, applications, and services. Skills of a user are learned over time, such that an electronic model of random subject matter may be generated. The user is prompted to interpret the random subject matter, such as with a drawing, physical arrangement, or performance. The user'"'"'s interpretation is then compared to the electronic model of the random subject matter. If the user is truly who they purport to be, their interpretation will match the electronic model, thus authenticating the user. If interpretation fails to match the electronic model, authentication may be denied.

7. A system, comprising:
-
a processor; and memory storing instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising; retrieving sketching skills associated with a user; receiving randomly selected subject matter for authentication of the user; generating a freehand model of the randomly selected subject matter using the sketching skills associated with the user; prompting the user to sketch the randomly selected subject matter; receiving data describing the sketch of the randomly selected subject matter drawn by the user; comparing the data to the freehand model of the randomly selected subject matter generated using the sketching skills associated with the user; and authenticating the user in response to a match between the data and the freehand model of the randomly selected subject matter. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:
-
retrieving sketching skills associated with a user; receiving randomly selected subject matter for authentication of the user; generating a freehand model of the randomly selected subject matter using the sketching skills associated with the user; prompting the user to sketch the randomly selected subject matter; receiving data describing the sketch of the randomly selected subject matter drawn by the user; comparing the data to the freehand model of the randomly selected subject matter generated using the sketching skills associated with the user; and authenticating the user in response to the data matching the freehand model of the randomly selected subject matter. - View Dependent Claims (15, 16, 17, 18)
