Abstract: Trust systems and methods include receiving a request from a first user, wherein the request is to a second user and relates to the second user sharing verified facts, attributes, and other pertinent information used by the first user in determining a level of trust to be afforded to the second user; providing the request to the second user for consent and for data acquisition related to the request; performing data acquisition responsive to the consent to obtain data; determining a response to the request based on the data; and providing the response to the first user, wherein the response is a minimum subset or derivative of the data required to answer the request so that the data is only shared with the first user on a limited basis.

Abstract: A computer-implemented method for managing a personal data store is described for binding one or more identities of different types associated with a user. The computer-implemented method is implemented in a trust system including one or more processing devices communicatively coupled to a network. The computer-implemented method includes receiving one or more self-asserted first attributes by the user and second attributes asserted by an Attribute Provider; utilizing one or more of the first attributes and the second attributes as inputs to obtain and/or produce one or more cryptographically signed attributes signed by an associated Attribute Provider; storing the first attributes, the second attributes, and the one or more cryptographically signed attributes in a personal data store associated with the user; and utilizing one or more of the first attributes, the second attributes, and the one or more cryptographically signed attributes to respond to a request from a Relying Party.
