Systems and methods for secure transaction management and electronic rights protection

This system creates a secure digital space to manage and protect electronic information, ensuring it's only used as intended. It works by setting up a protected computer environment that stores encrypted data and keeps the decryption keys in a secure, specific location, such as a specially marked area on a hard drive. This allows for controlled distribution and monitoring of digital content.

Why it matters: Filed before modern hardware-backed security, like TPMs and secure enclaves, became standard. These advancements make building the claimed secure processing environment and robust key storage significantly more practical and secure than in 2001.
