Electronic Receipt System Using Code-Based Identity Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers are concerned about the potential leakage of personal information related to their purchase history and preferences when using electronic receipts, due to risks such as server attacks and communication route intrusions.
Innovation Solution
An electronic receipt system that includes a code issuance server, a POS terminal, and an electronic receipt management server, which uses a two-dimensional code to securely transmit and manage electronic receipt information without linking it to personal information, thereby preventing information leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic receipt information is transmitted and stored on servers, then consumers can receive electronic receipts without paper, but personal information may leak to third parties due to server attacks or communication intrusions
Solution Approach 1:
The patent extracts and removes personal information from the electronic receipt data structure. The system transmits and stores only purchase information without any personal identifiers, effectively separating useful receipt data from sensitive personal information to eliminate the leakage risk while maintaining electronic receipt functionality
Solution Approach 2:
The patent introduces a code-based intermediary system where a unique code serves as a mediator between the purchase transaction and the consumer's mobile terminal. This code acts as a safe intermediary that links the receipt data to the consumer without requiring direct transmission or storage of personal information, thus preventing information leakage while enabling electronic receipt delivery
2Reliability
If personal information is linked with electronic receipt information, then receipts can be delivered to specific consumers, but the system becomes vulnerable to attacks and information leakage
Solution Approach 1:
The patent extracts personal information from the electronic receipt system entirely. Instead of storing or transmitting personal data linked to receipts, the system uses only purchase information and a separate code-based identification mechanism, removing the vulnerability source while maintaining accurate receipt delivery to the intended consumer
Solution Approach 2:
The patent creates a code-based copy or representation of the consumer's identification rather than using actual personal information. This code serves as a safe surrogate that enables accurate receipt delivery without exposing or storing sensitive personal data, thus maintaining reliability while eliminating information leakage risks

AI summary
An electronic receipt system according to example embodiments includes: a code issuance server configured to issue a code in response to a request from a mobile terminal and to transmit the code to the mobile terminal; a POS terminal configured to read the code displayed on a screen of the mobile terminal, to transmit the code to the code issuance server for inquiry, and when it is confirmed that the code is one that is issued by the code issuance server, to associate the code and electronic receipt information generated when performing transaction processing with each other; and an electronic receipt management server configured to save the code and the electronic receipt information that are associated with each other received from the POS terminal and when the mobile terminal transmits the code, to transmit the electronic receipt information that is associated with the code to the mobile terminal.
