Data Residency Proxy for PII Isolation and Tokenization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud-computing and Software as a Service (SaaS) providers face challenges in complying with data residency regulations that require personally identifying information (PII) to be stored within specific jurisdictions, as 'safe harbor' laws are under attack and manual data residency solutions are prone to errors and violations.
Innovation Solution
A data residency protection component is generated and deployed within a protected domain environment, acting as a proxy to isolate PII and prevent its visibility outside, using a centralized system that automates configuration, tokenization, and updates to ensure compliance with data residency regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored locally within jurisdiction to comply with data residency regulations, then data security and compliance are improved, but access to cloud services and productivity are reduced
Solution Approach 1:
A data residency proxy is introduced as an intermediary component deployed within the protected domain environment. The proxy intercepts data access requests, tokenizes PII data locally, and manages data residency compliance automatically. This allows cloud services to access necessary data while ensuring PII remains protected within the jurisdiction, thus resolving the contradiction between compliance and service access.
2Reliability
If manual data residency management is implemented, then data protection is attempted, but errors and compliance violations occur due to human error
Solution Approach 1:
The data residency proxy operates autonomously within the protected domain environment, automatically tokenizing PII data, managing data access requests, and ensuring compliance without requiring manual intervention. The system self-regulates data protection mechanisms, eliminating human error while maintaining high compliance accuracy through automated enforcement of data residency policies.
3Reliability
If PII data is isolated within protected domain environment, then data residency compliance is improved, but service functionality and data accessibility are reduced
Solution Approach 1:
The system transforms PII data into tokenized representations that change the data's form while preserving its functional utility. The proxy manages tokenization parameters and mapping relationships, allowing cloud services to perform operations on tokenized data that mirror operations on original PII data. This maintains service functionality while ensuring compliance, as the tokens can be processed externally but cannot be reverse-engineered to reveal original PII.

AI summary
Computerized embodiments are disclosed for keeping personally identifying information within a protected domain environment when interacting with a computerized service environment. A restriction to be imposed on access to personally identifying information that is stored within a protected domain environment is received. A data residency protection component is generated based on the received restriction, stored in a data residency database that is accessible to the computerized service environment, and transmitted to a remote computerized system included in the protected domain environment. The data residency protection component is configured to, when executed: monitor data communications from the protected domain environment to detect the personally identifying information, generate a protected communication by isolating the personally identifying information, and transmitting the protected communication having the personally identifying information isolated. The record corresponding to the data residency protection component is reference to avoid creating a second data residency protection component that counteracts the restriction.
