Abstract: Techniques for mitigating the transitive data problem using a secure asset manager are provided. These techniques include generating a secure asset manager compliant application by tagging source code for the application with a data tag to indicate that a data element associated with the source code is a sensitive data element, accessing a policy file comprising transitive rules associated with the sensitive data element, and generating one or more object files for the application from the source code. These techniques also include storing a sensitive data element in a secure memory region managed by a secure asset manager, and managing the sensitive data element according to a policy associated with the sensitive data element by an application from which the sensitive data element originates, the policy defining transitive rules associated with the sensitive data element.

Abstract: A methodology and apparatus for layered licensing is described. A licensable item is detected on a device. A legacy license associated with the licensable item is accessed, wherein the legacy license corresponds to a legacy licensing policy. A layered license associated with the licensable item is accessed, wherein the layered license corresponds to a layered licensing policy. The legacy licensing policy and the layered licensing policy are integrated into an integrated license, and the integrated license is enforced.
