Customer Identifier Resolution Using Hashed PII Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating universal customer identifiers (UUIDs) are insecure due to direct use of personal identifiable information (PII) and inefficient due to complex data processing, making them vulnerable to security breaches and costly.
Innovation Solution
A UUID management application generates user signatures using deterministic functions on PII attributes, calculates confidence scores based on reference weights, and integrates with a customer database to manage UUIDs securely and efficiently, allowing real-time identity resolution across systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If direct use of PII is made for UUID generation, then the process is simple, but security is compromised and vulnerability to breaches increases
Solution Approach 1:
The patent introduces a hashing function as an intermediary between PII and UUID. The hashing function processes PII attributes and transforms them into a secure UUID, preventing direct exposure of PII while maintaining the ability to identify users. This intermediary layer resolves the contradiction by enabling simple identification without compromising security.
Solution Approach 2:
The patent creates a hashed copy of PII attributes rather than using the original PII directly. The hash function generates a derived representation (copy) of the PII that can be used for identification purposes without revealing the actual PII. This copying approach allows the system to maintain security while preserving identification capability.
2Measurement precision
If complex data processing is used for UUID generation, then accuracy may improve, but processing time and cost increase
Solution Approach 1:
The patent pre-processes and stores hashed PII attributes in a database structure that is optimized for quick retrieval. By preparing the data in advance and using efficient data structures, the system achieves fast UUID generation without requiring complex real-time processing. This preliminary action reduces processing time while maintaining accuracy.
Solution Approach 2:
The patent replaces complex mechanical data processing operations with a more efficient hashing mechanism. Instead of performing complex comparisons and processing, the system uses hash functions that can quickly generate and match UUIDs, substituting complex operations with simpler, faster cryptographic operations that maintain accuracy.
3Adaptability or versatility
If third-party services are used for UUID management, then functionality is provided, but cost and dependency on external services increase
Solution Approach 1:
The patent implements a self-service UUID management system where the organization's own computing resources and processing capabilities are used to generate and manage UUIDs. Instead of relying on external third-party services, the system uses internally deployed hashing functions and databases, eliminating dependency on external services and reducing associated costs while maintaining full functionality.
Data Source
AI summary
A method of providing efficient universal user identifier (UUID) generation and resolution. The method includes receiving records associated with a user across different data sources, wherein each of the records comprises one or more personal identifiable information (PII) attributes; generating first signatures, each based on one or more PII attributes in a respective one of the records; searching for the first signatures in a database comprising UUIDs in association with customer signatures; determining, based on the searching, that one or more first signatures of the first signatures respectively match to one or more customer signatures of the customer signatures associated with a first UUID of the UUIDs; calculating a confidence score for the one or more matched customer signatures; determining that the user is a customer based on the confidence score satisfying a threshold; and configuring a telecommunications service configuration for the user based on the user being the customer.
