Abstract: Systems and methods providing access control and data privacy/security with decentralized ledger technology are disclosed. To ensure data privacy the decryption or access to data by a non-data owner requires joint orchestration of decentralized system nodes to provide partial decryption components with n-of-x required to fulfill request. Data can be encrypted, and access control policy can be decided including required number of key fragments to fulfill decryption. Access control policies can be stored in the decentralized ledger based system. Key information can be stored in the system in a decentralized manner with partial key fragments encrypted and split among system nodes. An access request can be sent to the system to fetch a data file, without disclosing the requester's identity in the system. The decentralized ledger based system can verify a legitimate request to access the data and denies access to malicious or faulty participants.

Abstract: Systems and methods providing user privacy in association with decentralized ledger technology are disclosed. Improved methods and systems for access control are disclosed wherein an access request can be received at the distributed ledger to fetch a data file without disclosing requester identity, that can verify the access request at the decentralized ledger as a legitimate request or as a malicious/faulty request, and can assist a user of a legitimate request to access the data and deny access to malicious/faulty requests that are compatible with a decentralized ledger environment.
