  • a policy/domain handler configured to receive data and a policy associated with the data;

    a hypervisor; and

    a file management module configured toreceive a request from a third-party application to interact with a data file containing the data;

    send an authorization and tag request to the policy/domain handler to generate hardware tags for the data file; and

    send a secure data request to the hypervisor to create a secure data compartment for the data file and the hardware tags;

    wherein, based on the tag request, the policy/domain handler generates the hardware tags for the data file, if the authorization check succeeds, andwherein, based on the secure data request, the hypervisor creates in the physical memory a secure data compartment containing the data file and the hardware tags, the hypervisor associating the hardware tags with the data in the secure data compartment.
