Patent ID: 8868423

Claim:
A method of controlling access to one or more resources using a computing system comprising: coupling the computing system to a voice reference database containing voice reference data for both human and machine related entities; processing a request for access from a first unverified entity with the computing system to the one or more resources; in response to said request for access to the computing system from said first unverified entity, presenting an access challenge task with the computing system; wherein said access challenge task requires that said first unverified entity provide an input utterance with at least some entity related audio information to the computing system as part of a challenge response in order to be satisfied; processing said entity related audio information input with the computing system based on a comparison to said voice reference data for both human and machine related entities; performing a determination with the computing system or a second computing system as to whether said first unverified entity is a human or a machine; controlling with the computing system whether said first unverified entity is allowed to access the one or more resources based on said determination.
