USER IDENTITY AND TRUST MODELS IN DECENTRALIZED AND DISTRIBUTED SYSTEMS

摘要

A method for sharing information has an assertion associated therewith such that the receiving communication device is able to verify the assertion without the sender revealing underlying data demonstrating the validity of the assertion. The assertion is derived from underlying data input to a pre-provisioned first algorithm. The assertion is encapsulated in a first data object by a PGE that controls an environment in which the first algorithm is executed. A first proof is generated that is configured to verify that the first algorithm used the underlying data to produce the assertion when provided to a PVE along with the first data object. The underlying data is excluded from the first proof and the first data object such that privacy of the underlying data is maintained. The information, the first proof and the first data object are sent to the receiving communication device from the sending communication device.
