Abstract

In the era of big data, all countries and governments generally attach importance to the opening of scientific data and actively promote data sharing.The wide opening and sharing of data poses new challenges to the whole process of data security.Based on the latest policies of international scientific data sharing and the actual situation in China, the resource and user access control system of scientific data center was put forward.Through the application of data classification, user classification and system access control strategy on the open system platform, the problem of lack of systematic scheme for resource security sharing in the data center was solved.The research results have been applied to the practical work of the National Earth Observation Scientific Data Center and achieved good results.
