Abstract
The present disclosure relates generally to data access control solutions. In particular, techniques are provided to implement a secure and distributed file storage scheme and in particular, a managed access system using a blockchain. In some aspects, a process of the disclosed technology includes operations for associating a first key share with a first copy of a file, wherein the first copy of the file is stored by a first party, associating a second key share with a second copy of the file, and recording versioning information corresponding with the file on a distributed ledger accessible by the first party and the second party. In some aspects, the process can further include operations for managing access to the file using the first key share and the second key share. Systems and machine-readable media are also provided.
