Abstract
The present invention discloses a method for managing cloud service authority in a cloud storage system, which includes: a set of cloud data and a plurality of data servers. The cloud data includes a plurality of user object files and global access control information. Each data server includes an access control enforcement unit for executing or rejecting I/O requests from the client computers, where the access control enforcement unit includes local access control information. The method includes steps of: changing the content of the global access control information in the cloud data; downloading, by the data servers, the changed global access control information from the cloud data; updating, by the data servers, the local access control information therein according to the downloaded global access control information; and processing, by the data servers, I/O requests from the client computers according to the updated local access control information.
