Abstract
An authentication framework is provided which enables dynamic user authentication that combines multiple authentication objects using a shared context and that permits customizable interaction design to suit varying user preferences and transaction/application requirements. Such a framework provides a high degree of flexibility, accuracy, convenience and robustness. In one illustrative aspect of the invention, an automated technique for user authentication comprises the following steps/operations. First, user input is obtained. At least a portion of the user input is associated with two or more verification objects. Then, the user is verified based on the two or more verification objects in accordance with at least one verification policy operating on a context shared across the two or more verification objects. The user authentication technique of the invention may preferably be implemented in a flexible, distributed architecture comprising at least one client device coupled to at least one verification server. The client device and the verification server may operate together to perform the user authentication techniques of the invention.
