In one embodiment, a human interactive proof portalmay use a biometric input to determine whether a user is a standard user or a malicious actor. The human interactive proof portalmay receive an access requestfor an online data servicefrom a user device. The human interactive proof portalmay send a proof challengeto the user devicefor presentation to a user. The human interactive proof portalmay receive from the user devicea proof responsehaving a biometric metadata descriptionbased on a biometric input from the user.

Using the ability to speak as a human interactive proof

A processing system is described which generates stimulus information (SI) having one or more stimulus components (SCs) selected from an inventory of such components. The processing system then presents the SI to a group of human recipients, inviting those recipients to provide linguistic descriptions of the SI. The linguistic information that is received thereby has an implicit link to the SCs. Further, each linguistic component is associated with at least one feature of a target environment, such as a target computer system. Hence, the linguistic information also maps to the features of the target environment. These relationships allow applications to use the linguistic information to interact with the target environment in different ways. In one case, the processing system uses a challenge-response authentication task presentation to convey the stimulus information to the recipients.
