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).

主权项

1. A distribution system operable in a computing environment for binary-encoded digital assets, comprising:
(a) a hiding means for hiding one or more keys or cryptography implementation in a digital asset; (b) a copying means for asset distribution for receiving a functionally-restricted asset copy for use or further distribution, directly or as a further copy, with or without access to a computer network; and (c) a self-policing means for enforcing asset safety, comprising:
i. an authentication means for an un-authenticated, digital asset for constructing encrypted credentials data using one or more keys or cryptography implementation hidden in the asset by the hiding means, for authentication by an authenticated digital asset or website;ii. a secure selling means for an authenticated digital asset for either carrying out a sale transaction directly, securely, or delegating the sale to a separate secure means, identifying the delegation by an encrypted identifier constructed using one or more keys or cryptography implementation hidden in the asset by the hiding means and decrypting the response from the secure means using the one or more keys or cryptography implementation hidden in the asset to determine the success of the sale; andiii. a copyright and license enforcement means for an asset for carrying out encryption and decryption of computing context and other data using one or more keys or cryptography implementation hidden in the asset by the hiding means, with functionally-unrestricted asset use permitted only after the asset has been sold and licensed to run in a recognizable computing context.
