Privacy Server Tokenizing PII for Cross-Jurisdictional Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting personally identifiable information (PII) across jurisdictions are costly and complex, limiting access to applications and services due to legal restrictions on data transmission, as they often require separate hosting or special handling for different jurisdictions.
Innovation Solution
A privacy server that intercepts communications, replaces PII with a token or identifier, and maintains the original information locally, allowing transparent protection and access to applications hosted outside the user's jurisdiction without altering existing systems or infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a provider hosts application or service within a specific jurisdiction or provides special handling for PII, then compliance with jurisdictional laws is improved, but cost and complexity increase
Solution Approach 1:
The patent introduces a privacy server as an intermediary component that sits between the application server and the user. This privacy server handles all PII-related operations including token generation, token mapping, and token resolution, allowing the application server to remain jurisdiction-agnostic while compliance requirements are met through the intermediary's location and operations.
Solution Approach 2:
The system segments PII handling into distinct functional components: token generation, token storage, and token resolution. The privacy server separates the storage of actual PII from the application logic, maintaining PII in a local database while using tokens in communications. This segmentation allows compliance to be enforced at the privacy server level without complicating the application server infrastructure.
2Reliability
If a user limits themselves to applications and services hosted within their jurisdiction or with special PII handling, then PII protection is improved, but access to available resources is reduced
Solution Approach 1:
The privacy server acts as a mediator that enables users to access applications hosted in any jurisdiction while maintaining PII protection. The application server communicates with the privacy server using tokens, and the privacy server ensures that actual PII never leaves the user's jurisdiction, thus providing both universal access and localized protection.
Solution Approach 2:
The system creates a token copy that represents the PII without exposing the actual PII data. The token serves as a surrogate that can be transmitted freely to application servers anywhere in the world, while the original PII remains securely stored in the privacy server within the user's jurisdiction. This copying mechanism enables universal access without compromising data sovereignty.
3Adaptability or versatility
If PII is transmitted outside the jurisdiction, then access to external applications is improved, but compliance with jurisdictional laws deteriorates
Solution Approach 1:
Instead of transmitting actual PII outside the jurisdiction, the system transmits a token copy that can be used externally. The token contains no sensitive information but uniquely identifies the user, enabling access to external applications while the actual PII remains within the jurisdictional boundary, thus maintaining compliance.
Solution Approach 2:
The privacy server serves as a jurisdictional intermediary that controls all PII-related communications. It intercepts PII before it leaves the jurisdiction, replaces it with tokens, and manages all external communications using only non-sensitive token data. This intermediary approach enables external access while enforcing jurisdictional boundaries on actual PII.

AI summary
A privacy server protects private information by substituting a token or an identifier for the private information. The privacy server recognizes that a communication includes private information and intercepts the communication. The privacy server replaces the private information with a random or pseudo-random token or identifier. The privacy server maintains the private information in a local database and associates the private information for a particular person with the token or identifier for that person.
