Layered secure data management system

Abstract

The invention relates to a layered secure data management system. The system comprises a cross-department server, an important information server, a redundancy server, a shared server and a managementserver. The shared server is used for storing shared information visible to system users, wherein the shared information can be accessed through utilization of common authority of the system. The important information server is used for storing important information visible to few system users, wherein the important information can be accessed through utilization of advanced authority. The cross-department server is used for storing cross-department information and storing information of various departments regionally, wherein the department information is visible to all users belonging to the departments and the users with access authority in the other departments. The redundancy server is used for keeping redundancy data of the cross-department server and the important information server. According to the system, the layered management can be carried out on cross-department shared information, the redundancy management can be carried out on the important data and authority data, thesecurity of the data is ensured, and the redundancy mirroring efficiency is improved.

Description

【Technical field】 [0001] The invention belongs to the field of data processing and sharing, in particular to a layered security data management system. 【Background technique】 [0002] At present, with the rapid development of the national economy, urban development has shown the characteristics of network, digitization, informationization and intelligence. Especially in recent years, information resources have increasingly become an important part of the urban resource system and urban production factors, and their leading and supporting roles in economic and social development have further emerged. In this context, some countries, regions and cities took the lead in proposing the development strategy of building smart cities. Smart city is to endow the city with various resource elements through advanced information technology, generate a large number of information resources, promote the construction and integration of urban information resource system, and realize the ef...

Problems solved by technology

[0003] The existing urban information resource system does not support hierarchical management of shared data, nor does it pay attention to the need for secure data management of data at different levels. A new system is urgently needed that can share data across departments Hierarchical management, redundant management of important data and authority data, thus ensuring data security in the case of multiple users, in addition, dynamic area division of redundant data storage areas according to the amount of data at each level, Improved efficiency of redundant mirroring
