Pseudonymous Credential Verification With Custodial Data Escrow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital identity systems face challenges in verifying user identities and authenticating credentials while minimizing personal data aggregation, complying with varying data protection laws, and ensuring compliance with data retention and due process requirements across national borders.
Innovation Solution
A system that utilizes pseudonymous transaction records stored in a shared ledger and custodial escrow accounts to verify user identities and credentials, with due process rules determining access to identifying information, enabling compliance with diverse legal frameworks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal data is aggregated and stored in centralized databases for identity verification, then authentication reliability is improved, but data security risks and privacy violations increase
Solution Approach 1:
The patent extracts personal data from centralized databases and places it in decentralized custodial escrow accounts on the blockchain. Only pseudonymous transaction records are stored on-chain, while actual identifying information remains in secure offline storage, eliminating the need for centralized data aggregation and reducing security risks.
Solution Approach 2:
The patent introduces a custodial escrow system as an intermediary between users and service providers. This escrow holds personal data in trust and releases it only when due process requirements are met, acting as a mediator that protects both user privacy and legitimate access needs without requiring centralized data storage.
2Ease of operation
If centralized data storage is used for identity verification, then access to personal data is simplified, but compliance with varying data protection laws becomes difficult
Solution Approach 1:
The patent implements a dynamic access control system where the custodial escrow automatically adjusts data access based on the applicable law for each transaction. The system determines which jurisdiction's data protection rules apply and configures escrow access accordingly, enabling compliance with varying laws without manual intervention.
Solution Approach 2:
The patent changes the parameter of data accessibility from static centralized storage to dynamic conditional access. Personal data is stored securely but becomes accessible only when specific conditions (due process rules, jurisdictional requirements) are met, allowing the system to adapt to different legal frameworks.
3Object-affected harmful factors
If pseudonymous transaction records are stored on a shared ledger, then data privacy is improved, but access to identifying information for due process requirements becomes more complex
Solution Approach 1:
The custodial escrow acts as an intermediary that simplifies the complex process of accessing pseudonymous data. It handles the technical complexity of correlating blockchain records with identifying information and manages the due process evaluation, presenting a simplified interface for legitimate access requests.
Solution Approach 2:
The patent creates a copy of the identification process through the custodial escrow system. Instead of requiring direct access to centralized databases, the escrow maintains a copy of identifying information that can be accessed under the same due process rules, simplifying the access mechanism while maintaining privacy.
4Speed
If centralized identity verification systems are used, then processing speed is improved, but loss of personal data control and user autonomy increases
Solution Approach 1:
The patent enables users to control their own personal data through the custodial escrow system. Users retain ownership of their data and can authorize access when needed, eliminating the need to surrender data control to centralized authorities while maintaining efficient verification processing.

AI summary
The invention advantageously provides a system for the verification a user's identity and qualifications and authentication of credentials associated with a user's digital identity on a trust network (where service providers involved in a transaction may be independent parties operating with limited trust), in which a pseudonymized transaction record may be created for that digital identity and stored in a shared ledger; identifying information for a user may be retained in a custodial escrow account for that user; and transactions may be re-correlated with identifying information for authorized third parties under established "due process" rules that are appropriate for the applicable jurisdiction(s).
