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

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