  • Patent number: 10185584
    Abstract: Disclosed is a system comprising a physical memory, a processor and a software component. The software component includes a policy/domain handler for receiving data and a policy associated with the data; a hypervisor; and a file management module. The file management module receives a request from a third-party application to interact with a data file containing the data; sends an authorization and tag request to the policy/domain handler to check if the user and application are permitted to access the data, and if permitted, to generate hardware tags for the data file; and sends a secure data request to the hypervisor to create a secure data compartment for the data file and the hardware tags. Based on the authorization and tag request, and the security policy associated with the data, the policy/domain handler generates the hardware tags for the data file.
