Abstract
A system that that dynamically authenticates one or more users is described. During operation, the computer system determines a trust level for a user, where the trust level is a function of elapsed time since the user previously provided authentication information. Next, the computer system calculates a transaction risk level based on a type of user transaction performed by the user. Then, the computer system requests additional authentication information from the user based on the trust level and the transaction risk level.
