Cloud data uploading and access control method

Abstract

The invention provides a cloud data uploading and access control method. A server receives and stores cloud data with security levels; after the server receives a cloud data access request, key authentication is carried out on an access user; if key authentication is successful, the server allows the access user to carry out read and write operation on the cloud data, and otherwise, code authentication is carried out on the access user; the server obtains the security level corresponding to the cloud data when code authentication is successful, the server allows the access user to carry out read and write operation on the cloud data if the security level is normal, the server allows the access user to carry out read-only operation on the cloud data if the security level is important, and the server refuses the access request if the security level is confidential. Due to the fact that the cloud data have the corresponding security level, the access user can only be in an authority range and operate the cloud data of different security levels, and accordingly security and privacy of cloud data access are enhanced.

Description

technical field [0001] The invention relates to the field of cloud storage security, in particular to a cloud data upload and access control method. Background technique [0002] Cloud storage is a new concept extended and derived from the concept of cloud computing. In terms of function realization, it is a technology that realizes remote file access and file sharing. Cloud storage usually means putting primary or backup data in external storage pools rather than in local data centers or dedicated remote sites. Using cloud storage services, organizations can save investment costs, simplify complex setup and management tasks, and put data in the cloud to facilitate access to data from more places. Cloud storage has become a trend in the future storage development, but with the development of cloud storage technology, the combination of various search, application technology and cloud storage needs to fully consider the hidden dangers of private file protection, and from th...

Problems solved by technology

[0003] With the rapid development and popularization of cloud storage technology, more and more mobile platform users like to quickly upload photos and videos taken with their mobile phones or tablets or personal logs to the network disk through cloud storage at any time, which can be very fast The photos and logs can be retrieved even in real time through the WEB or PC client, but every photo or other file uploaded by the user is stored in clear text on the cloud storage server, and there is no lack of confidential files or user privacy in these files. , once the personal cloud storage space is cracked, it will lead to the disclosure of sensitive information; in addition, implementing key encryption for all files on the server will increase the cost
