TVS: a trusted verification scheme for office documents based on blockchain

Abstract

To realize the encryption of document information, authority authentication, and traceability of historical records, we propose a trusted verification scheme (TVS) for office documents to ensure security. Specifically, the scheme is realized by timestamps, smart contracts (or chaincode), and other blockchain technologies. It is based on the features of blockchain, such as security, credibility, immutability, and traceability of network behavior. And the TVS stores users and documents information through blockchain; it can monitor the state changes of office documents in real time by setting the trigger conditions of smart contracts. The experiment indicates that we have realized the real-time monitoring of data and the traceability of historical records. Moreover, we have achieved the purpose of document encryption and authority authentication, ensuring the authenticity and objectivity of data, avoiding the illegal tampering of malicious users to realize the trusted verification for documents.

“…The most common problem is the public on-chain storage of all data, which, in addition to having many privacy concerns, is also an extremely expensive approach [56]. In a permissioned manner, a centralized distributed system is implemented with blockchain characteristics [57,58]. The solutions mentioned in the papers [38,59,60] are less secure compared to a decentralized approach due to this centralized characteristic.…”
