Towards a Blockchain based digital identity verification, record attestation and record sharing system [article]

Mehmet Aydar and Serkan Ayvaz and Salih Cemil Cetin
2020 arXiv   pre-print
As a result, we propose a Blockchain based framework for digital identity verification, record attestation and record sharing, and we explain the framework in details with certain use cases.  ...  Our proposed framework promotes individuals to fully control their identity data and govern the level of the identity data sharing.  ...  In Hyperledger Fabric, identities are essential since apart from asset ownership, management of resource and access permissions is also determined based on actor identities.  ...
