A Monitor System for Software Version Request in Offline Environments

Abstract

While the Internet allows licensees to easily disseminate digital content, it also facilitates misappropriation of such content along with violations of personal privacy. Digital rights management (DRM) measures were developed to address such problems. However, DRM can only be used to verify data correctness from software, but cannot be used to verify software soundness from data. In addition, although trusted platform modules (TPM) can be used to achieve system security, such measures to not provide DRM protection. We thus propose a version request system not only achieves DRM functions, but can also conduct version requests for software from data. In this system’s version checking restrictions, only a secure operation system and application can store the cryptography component’s secret key, which is then used to protect and manage the right object (RO).
