Sound Wave Payment Authentication via Acoustic Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment systems that rely on offline authentication using barcodes or QR codes require additional hardware, such as scanners, which increases costs and complexity for merchants, hindering service expansion.
Innovation Solution
A method where a buyer terminal acquires identification information from a sound wave output by a seller terminal, verifies its validity, and transmits this information to a payment application server for secure payment processing, eliminating the need for additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If barcode or QR code based offline authentication is used, then payment authentication can be performed, but additional hardware scanners are required which increases cost and complexity
Solution Approach 1:
The patent replaces the mechanical/optical scanning system (barcode scanners, QR code readers) with an acoustic system using sound waves. The seller terminal emits sound waves containing encoded identification information that the buyer terminal captures through its microphone, eliminating the need for additional scanning hardware while maintaining authentication reliability
Solution Approach 2:
The patent introduces sound waves as an intermediary carrier to transmit identification information between the seller terminal and buyer terminal. Instead of direct visual scanning or physical contact, the sound wave acts as a mediator that conveys encoded data through the air, enabling authentication without additional hardware
2Adaptability or versatility
If sound wave based authentication is implemented, then hardware requirements are reduced and service expansion is facilitated, but identification information must be encoded in sound wave which requires new processing methods
Solution Approach 1:
The patent changes the parameter of information encoding from visual patterns (barcode/QR code) to acoustic parameters (sound wave frequency, amplitude, or time-domain characteristics). The identification information is embedded in sound wave parameters that can be captured by standard microphones and processed through signal analysis algorithms
Solution Approach 2:
The patent makes the buyer terminal's microphone serve multiple functions: it acts as both a standard audio input device and a sound wave receiver for authentication. This multi-functionality eliminates the need for dedicated scanning hardware while maintaining the terminal's existing capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances payment convenience and simplifies service integration for merchants by allowing sound wave-based authentication, reducing hardware requirements and improving payment security.
Implementation Method 1
a seller terminal outputs a sound wave, and a buyer terminal acquires identification information based on the sound wave
Data Source
AI summary
A method of operating a service server is disclosed. One embodiment comprises the steps of: receiving, from a payment application server, identification information obtained by a buyer's terminal and dynamic code information created by a request of the buyer's terminal; determining whether or not the obtained identification information is valid; on the basis of the determining result, mapping the obtained identification information to the dynamic code information; and transmitting the mapping information created on the basis of the mapping to the payment application server.
