Potentate: A Cryptography-Obfuscating, Self-Policing, Pervasive Distribution System For Digital Content

摘要

A system and method for self-policed, authenticated, offline/online, viral marketing and distribution of content such as software, text, and multimedia with effective copyright and license enforcement and secure selling. The system is based on key and cryptography hiding techniques, using source-to-source transformation for efficient, holistic steganography that systematically inflates and hides critical code by: computation interleaving; flattening procedure calls and obfuscating stack by de-stacking arguments; obfuscating memory management; and encoding scalars as pointers to managed structures that may be distributed and migrated all over the heap using garbage collection. Multimedia/text content may be partitioned and sold with expiry dates for protection and updates for long life. Authenticity of software installed on a machine may be monitored and ensured, supporting even authentic software deployment in an unknown environment. The system can be implemented with commonplace networking or browser software, commonplace hardware and content provision over a secure website (https standard).
