Abstract
A computer system supports secondary authentication mechanism for authentication of a user, where the computer system may provide a variety of services including financial, scientific, academic, or governmental services. The computer system utilizes a multiphase distributed trust model in which the user is authenticated based on distributed trust of a set of randomly selected trusted contacts from a large set of trusted contacts initially chosen during an enrollment phase. During the authentication phase, a subset of contacts (affirmers) is selected from the contact list. The computer system then provides additional authentication information to each of the affirmers who subsequently share the information with the user. The user then provides this information from the computer system in order to complete the secondary authentication.
