Secure Network Ecosystem with Decentralized Token Authentication

The patent segments access control into multiple layers: ecosystem-level authentication, content-level permissioning, and token-based authorization. Each layer operates independently with specific security functions, replacing the monolithic centralized access control model. This segmentation allows convenience features to operate at higher levels while security enforcement occurs at granular content levels.

The patent introduces tokens as intermediary objects that mediate between users and content. These tokens encapsulate permission information and act as secure intermediaries that eliminate the need for direct centralized authentication checks for every access request. The tokens serve as self-contained authorization credentials that improve both security and operational efficiency.

The patent applies preliminary action by pre-computing and embedding permission information into tokens during content creation or sharing operations. This eliminates the need for complex real-time authorization calculations during access operations. The permission logic is prepared in advance and stored within the token structure, reducing runtime complexity while maintaining granular security control.

The patent changes the parameter representation from complex permission matrices to simplified token structures with defined fields (ecosystem ID, content ID, permission level, expiration). This parameter transformation reduces system complexity by converting multi-dimensional access control relationships into standardized, easily verifiable token objects that can be efficiently processed.

The patent implements universality by designing tokens with a standardized structure that can function across multiple ecosystems and application types. The token format includes universal fields (ecosystem ID, content ID, permission level) that enable the same authentication mechanism to serve file sharing, collaboration, streaming, and other cloud services. This multi-functional design allows a single authentication system to support diverse use cases and ecosystem integrations.

The patent adds the ecosystem dimension to traditional authentication by incorporating ecosystem IDs into the token structure. This dimensional extension allows the system to distinguish between different organizational or operational contexts while maintaining a unified authentication framework. The ecosystem dimension enables multi-tenant architectures and cross-organization collaboration without requiring separate authentication systems for each context.

The patent extracts permission information from centralized databases and embeds it directly into tokens that are distributed to clients. This extraction removes the single point of failure represented by centralized permission storage. Each client receives self-contained tokens with the necessary authorization information, eliminating the security risk associated with storing detailed permission data in a central location that could be compromised.

The patent enables self-service by designing tokens that contain all necessary permission information for clients to verify their own access rights without requiring centralized verification. Clients can independently validate token authenticity and their own authorization status by checking the embedded permission fields, reducing the need for centralized permission management while maintaining security. This self-verification capability distributes the security burden from the server to the client side.
