Methods, systems and apparatuses for secure transactions

Abstract

The invention is directed towards methods, systems and apparatuses, see FIG. 1, ( 100 ) for providing secure and private interactions. The invention provides capability for verifying the identity of a party initiating an electronic interaction with another party through data input module ( 140 ) which is verified by the ientity verification module ( 150 ), which further includes a self-destruct mechanism ( 153 ). Embodiments of the invention include secure methods for conducting transactions and for limiting the transfer and distribution of personal data to only those data that are absolutely necessary for the comletion of the transactions. The invention facilitates the transfer of additional personal data contingent upon an agreement that appropriately compensates the provider of the personal data.
