Abstract:
An application program data access isolation method and device. The method comprises: receiving an access request for second application program data from a first application program (101); determining whether the first application program is located in a domain having right to access the second application program data (102); if so, allowing the first application program to execute an access operation (103); otherwise, refusing to execute the access operation (104), wherein each application program belongs to a domain and has a domain attribute identifying the domain to which the application program belongs, application programs belonging to the same domain can access data of each other, and between different domains, there are a pre-set hierarchical relationship and an application program data access rule based on the hierarchical relationship. The method achieves a data isolation mechanism from a plurality of dimensions, can provide a reasonable data access right for an application program, and flexibly achieves data sharing between application programs.
