| Abstract: | Purpose/Significance] Data is not only the output of scientific research activities,but also the basis on which scientific research activities are carried out.Therefore,ensuring the quality of data and preventing data from being tampered with have become an important factor affecting research results.In order to avoid data fraud,data misreporting,and falsification of results to meet key scientific research goals and other data frauds,it is necessary to maintain the provenance of data.Methods/Process] The security threats of the provenance system were divided into internal factors and external factors.Based on smart contracts and open provenance models(OPM),the provenance access mechanism was implemented by voting.Changeability,proposed a reliable provenance collection,verification and management program.Results/Conclusions] In the process of creating,distributing,circulating,and reuse of scientific data,the system can effectively and safely capture and verify traceability records,prevent malicious changes of provenance,and thus provide ways for ensuring the objective and true scientific research data. |
