Abstract
A system and method of determining an attestation or identity score of a user of a communication device employs metadata stored in a plurality of client devices, such as IoT devices. A request for attestation, comprises a unique identifier associated with the communication device and an input or shared value. The unique identifier is used to identify, in a distributed ledger (blockchain), client devices that are paired with the communication device. Metadata stored in association with each of the client devices is retrieved and compared to the input or shared value, and a sub-identity score is determined based on the extent to which there is a match and the reliability of the client device. The sub-identity scores are combined to obtain an identity score reflecting a confidence level in the user and/or communication device.
