| Abstract(in English) | It has been difficult to keep evidentiary and fair records of important documents and other digital documents without using a third-party organization. In this study, we are trying to construct the document sharing system with high evidence and traceability utilyzing blockchains which are autonomous distributed ledger technologies. This paper describes a distributed access control and file tracking mechanism that links document entities with tokens in the blockchain. |
