USER IDENTITY AND TRUST MODELS IN DECENTRALIZED AND DISTRIBUTED SYSTEMS

摘要

A method is presented for sharing information between a sending device and a receiving device. The information being shared has an assertion associated therewith such that the receiving device can verify the assertion without revealing underlying data that demonstrates the assertion's validity. In accordance with the method, the assertion is derived from underlying data that is input to a pre-provisioned first algorithm. The assertion is encapsulated in a first data object by a proof generating engine. A first proof is generated that is usable to verify that the first algorithm used the underlying data to produce the assertion when provided to a proof verifying engine along with the first data object. The underlying data is excluded from the first proof and the first data object to maintain privacy of the underlying data. The information, first proof and first data object are sent to the receiving device from the sending device.
