Abstract
A person's drawing capability is used as an authentication credential. During a training phase, a user is asked to hand draw various reference shapes such as a rectangle, flower, etc. These user drawings for a given shape are input to a training discriminator (with an 'authentic' label) along with drawings automatically generated from a latent sample (with a “not authentic” label), and the training discriminator computes positive discrimination vectors for this shape that are unique to this user. Thereafter, when the user wants access to a resource (such as an online account, a mobile computing device, or an electronic document), the user is presented with a drawing challenge for one of the reference shapes, and they draw a corresponding challenge image. An image vector for the challenge image is generated, and if the image vector falls within the positive discrimination vectors, access to the resource is granted.
