Tokenized Confidential Document Generation Across Trust Boundaries

The patent introduces a token as an intermediary element that replaces confidential information in documents sent to vendors. The token serves as a mediator between the high-trust network (where confidential information is stored) and the low-trust network (where document generation occurs). The vendor receives documents with tokens instead of actual confidential information, generating documents without exposing sensitive data. The high-trust network then replaces tokens with actual confidential information before final delivery to the user.

The patent segments the document generation process into distinct phases: (1) generating a document template with tokens in the low-trust network, (2) replacing tokens with actual confidential information in the high-trust network, and (3) delivering the final document to the user. This segmentation allows the vendor to participate in document generation without accessing the actual confidential information, resolving the contradiction between enabling vendor document generation and preventing information theft.

The patent uses token copies of confidential information instead of the actual data in documents sent to vendors. These tokens are simplified representations (copies) that maintain the structural and functional needs of the document without containing the sensitive data. This copying approach maintains security while simplifying the vendor's processing requirements, as they only need to handle the token placeholders rather than complex security protocols.

The token acts as an intermediary that bridges the high-trust and low-trust networks. It provides a standardized interface that allows documents to flow between networks with different security levels without requiring complex authentication or encryption protocols at each step. The token simplifies the interaction between networks while maintaining security boundaries.
