Abstract: Personal content creation has become a significant part of the media industry, and sales are not necessarily the main objective of such creators. Individual creators have a greater need for privacy protection; therefore, the novel active content (AC) approach is proposed to address this need. The Intention Markup Language (InML) markup language is also introduced to express the content owner’s intentions systematically and precisely, and then to implement these as an executable code. To overcome the incompatibility and inconvenience of the existing digital rights management (DRM) systems, the novel AC format is proposed. This is based on the Portable Executable (PE) format and consists of a PE header and sections, followed by an AC header, the content, and the intention code. The proposed content virtualization technique protects the content against a variety of attacks by treating content in main memory as if it were stored on the user’s storage. Since external players, beyond the AC control boundary, may potentially expose the content, these are controlled by hooking code included in the intention engine while the AC is in use. Finally, example use cases are presented to show how intentions can be expressed in InML documents and the creation and use of an AC file on Windows is demonstrated.
