Abstract
Systems and methods are provided for authenticating a user. In one implementation, a computer-implemented method is provided. According to the method, transaction history information for each one of a set of users is maintained in a storage device. The method provides identifiers associated with items for display and receives, from one of the users, a selection of one or more of the identifiers. The method further authenticates the user as a function of the selection and a transaction history of the user.
