Authorization authentication method and system for cloud file sharing

Abstract

The invention provides a cloud file sharing authorization and authentication method and system. The method comprises the steps that a master user logs in a server by using a user name and a password thereof and uploads a file for sharing; through a user interface at the server end, the master user adds a master user token and a user name and a token of a slave user and sets the slave user access authority for the currently uploaded shared file; the master user notifies the slave user of the user name and the password of the master user and the token of the slave user, and after the slave user logs in the server with the user name and the password of the master user, the server obtains and verifies the token of the slave user; the server finds the user name of the slave user according to the verified slave user token and the slave user access authority for the shared file is obtained from the server. The method and system allow non-administrator users to set uploaded cloud sharing file access authority for different users, so that file leak and faulty modification are prevented; the method is convenient and quick and easy to implement, and the calculation amount is small.

Description

technical field [0001] The invention relates to the fields of mobile Internet and cloud computing, in particular to an authorization authentication method and system for cloud file sharing. Background technique [0002] A cloud file sharing service appears in the Internet and cloud computing, that is, a file is uploaded to the cloud, and then other people or other terminals download, browse, and edit the file. For example, Baidu Cloud, Kingsoft Cloud, etc., all provide cloud file sharing services. However, at present, this kind of service cannot provide precise access control to files, that is, after the main user who uploads the file uploads the file, other shared participating users, that is, the slave user, can have the same access control authority to the file as the main user, which results in The "single" access control authority leads to the lack of fine-grained file access authority, which is prone to security issues such as file leakage and mistaken modification.
