Abstract:
1. A system for performing proxy authentication between subscribers in a transaction, comprising: storage providers for maintaining subscriber identities and personal information, wherein for any specific subscriber the identity and personal information is only stored in one location, wherein the specific storage is managed by the specific subscriber; a central authority for authenticating the subscribers, that uses a combination of credentials for subscribers, along with combinations of devices and locations from which individual subscribers are authenticated; an authenticator to authenticate a first subscriber using a first credential and a second subscriber using a second credential; and a receipt generator to generate a receipt that identifies the first subscriber and the second subscriber without providing the personally identifiable information about the first subscriber and the second subscriber and using metadata and pseudo data for authentication so that the central authority does not know the true identities of the subscribers contained in the storage provider facilities.
