Embodiment Construction

[0110] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0111] The application scenario of the present invention is in a cloud system, and the cloud system includes a client, a server and a cloud management point. Usually the cloud system is also referred to as the cloud, or cloud data center. Wherein, a data file is stored in the server, and the data file may be a source data file or a copy file, and a file protection policy for the source data file and the copy file is stored in the cloud management point. When ...

Abstract

The present invention provides a method for managing a data file in cloud, a cloud management point, and a system. The method comprises: a first server calculates a file identifier of a data file to be processed currently, and sends the file identifier to a cloud management point, so that the cloud management point searches for a file protection policy of the data file according to the file identifier; the first server receives the file protection policy returned by the cloud management point; the first server determines, according to the file protection policy, whether the data file allows the first server to execute processing; and if yes, the first server processes the data file to be processed currently. In the present invention, multiple duplicate files generated from a source data file adopt a file protection policy the same as that of the source data file, and therefore, when an unauthorized user in the prior art accesses a duplicate file, the access of the duplicate file is also protected by the file protection policy, thereby preventing data leakage.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a management method, cloud management point and system for data files in the cloud. Background technique [0002] With the development of cloud computing technology, a large number of data files containing personal data (personally identifiable data, PII) are stored in the cloud system (referred to as the cloud). For the purpose of ensuring the availability of the user's data files, the cloud system usually copies the user's data files to generate multiple copy files, and stores the generated multiple copy files in different servers, or in different storage partitions of the same server. [0003] At present, ACL (Access control list, access control list) is mainly used for the protection of data files. ACL is a part of metadata of a data file, and defines different access rights (reading, writing, etc.) of different users in the system to the data file. ...
