Abstract

The invention discloses an information sharing method and device. According to the method, resources added into a to-be-shared packet are divided into a plurality of independent small resource packetsaccording to granularity, and each small resource packet can set the respective permission according to a permission strategy, so that the limited use of the information is ensured, the security of the shared information is enhanced, the use of the resources follows the permission of the resources, and unnecessary management overhead is avoided.

Description

technical field [0001] This application involves but is not limited to big data technology, especially an information sharing method and device. Background technique [0002] In the multi-tenant system of big data computing services, the following methods can be used to share data between tenants: one is to add users to the project (Project) that needs to share data, which will obviously lead to organizational confusion; One is to set two projects that need to share data as mutual trust projects, but this will confuse the concept of tenants; the other is to use packages to share data between different projects, and the contents of a package include All its permissions, as long as it is authorized to users in another project, it means that all the contents of a package will be authorized to all users in the project sharing the package, which will violate the principle of least authorization, thus It leads to data leakage due to excessive authorization; when you only want to ...
