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. 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. As the data is operated upon and moved to other memory areas, the hardware tags are …
