Access Control Management System for Secure Cryptographic Data Distribution

The patent introduces a digital rights management system as an intermediary that handles cryptographic operations automatically. The system includes a key management service that generates, distributes, and manages cryptographic keys without requiring users to understand cryptographic principles. This mediator layer shields users from technical complexity while maintaining strong security through automated key management and encryption/decryption operations.

The patent implements a universal digital rights management system that can secure data objects regardless of their origin or destination. The system provides unified key management and access control for data created inside or outside the system, and for data shared within or externally. The key management service generates cryptographic keys and manages access rights universally across all data objects and users, enabling consistent protection throughout the entire data lifecycle.

The patent implements a self-service key management system where the digital rights management infrastructure automatically handles public key distribution and management. Users do not need to manually obtain or manage public keys; instead, the system automatically provides the necessary cryptographic information through its services. The key management service stores and distributes public keys as needed, eliminating the need for users to perform mainstream-unfriendly key management tasks.
