Anonymized Transaction Receipt System for Secure Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transaction validation systems face challenges in providing secure, efficient, and user-friendly methods for remote validation, recordation, and tracking of transactions, particularly in electronic formats, which often require sensitive information and lack seamless data combination across purchases.
Innovation Solution
A system and method that utilize a processor and memory to receive and process transaction requests, query databases without sensitive information, actively scrub sensitive data, and generate receipt records, enabling secure and efficient transaction validation and tracking without exposing personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic receipts are issued to provide convenient storage and transaction validation, then storage convenience is improved, but security risks increase due to exchange of personal information
Solution Approach 1:
The patent extracts and removes sensitive personal information from the electronic receipt data structure. The system processes transaction data to exclude personally identifiable information (PII) such as names, addresses, and account numbers, retaining only essential transaction details for validation and storage purposes.
Solution Approach 2:
The patent introduces an intermediary processing layer between transaction capture and receipt generation. This intermediary system acts as a buffer that validates transactions, removes sensitive data, and generates anonymized receipt records, thereby mediating between the need for transaction validation and the requirement for information security.
2Measurement precision
If separate receipt documents are issued for each transaction, then transaction detail accuracy is improved, but data combination and analysis become impractical
Solution Approach 1:
The patent merges multiple separate transaction records into a unified electronic receipt system. The system consolidates transaction data from multiple sources and time periods into a single searchable database structure, enabling both detailed transaction tracking and aggregate data analysis without requiring separate physical documents.
Solution Approach 2:
The patent creates a universal electronic receipt platform that serves multiple functions: individual transaction validation, consolidated spending analysis, budget tracking, and tax documentation. The system is designed to handle diverse transaction types and provide multiple levels of data aggregation within a single system architecture.
3Measurement precision
If sensitive information is collected for transaction validation, then validation accuracy is improved, but user privacy and security concerns increase
Solution Approach 1:
The patent systematically extracts and removes sensitive personal information from transaction data before storage and processing. The system identifies and excludes personally identifiable information while retaining sufficient data for transaction validation, thereby maintaining validation accuracy without compromising user privacy.
Solution Approach 2:
The patent transforms sensitive personal information parameters into anonymized or aggregated parameters. Instead of storing identifiable data, the system uses hashed identifiers, aggregated spending categories, and statistical summaries that maintain validation capability while eliminating privacy risks associated with sensitive information storage.

AI summary
A system including: a processor; and a memory having stored thereon instructions that, when executed by the processor, controls the processor to: receive a receipt request for a transaction from a remote device, the receipt request comprising a merchant identifier, a transaction amount, and a transaction date and time; query the receipt database for a receipt record corresponding to the transaction based on the merchant identifier, the transaction amount, and the transaction date and time, the query being conducted without the benefit of sensitive information; in response to identifying a receipt record corresponding to the transaction, retrieve the receipt record corresponding to the transaction from the receipt database; and output for transmission the receipt record to the remote device.
