【Abstract】At present, the provenance of electronic records is stored centrally. The centralized way of information storage has huge risks. Whether the database itself is destroyed or the communication between the central database and the external interruption occurs, the provenance information of the stored electronic records will not play its role. At the same time, uncertainties such as fires and earthquakes will also pose a potential threat to centralized databases. Moreover, the existing security provenance model is not specifically designed for electronic records. In this paper, a security provenance model of electronic records is constructed based on PREMIS and METS. Firstly, this paper analyses the security requirements of the provenance information of electronic records. Then, based on the characteristics of blockchain decentralization, and combined with coding theory, a distributed secure provenance guarantees technology of electronic records is constructed, which ensures the authenticity, integrity, confidentiality and reliability of the provenance information.
