Audio-Based Transaction Authorization via Encoded Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic transaction authorization methods are insecure, inefficient, and costly, relying on text-based entry and requiring new devices, which limits their adoption and effectiveness.
Innovation Solution
The use of encoded audio messages to initiate, process, and complete transactions, allowing authorization through existing audio-capable devices like smartphones, tablets, and radios, minimizing the need for text-based entry and enabling secure, efficient transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text-based passwords and PINs are used for authorization, then user access can be verified, but security is compromised as passwords can be easily stolen or deduced
Solution Approach 1:
The patent replaces the mechanical system of text-based password entry with an acoustic signal transmission system. Audio messages are transmitted through communication channels and automatically processed by the receiving device, eliminating the need for manual text entry while enhancing security through encoded audio authentication
2Productivity
If manual text entry is required for authorization, then user verification can be completed, but the process becomes slow and error-prone
Solution Approach 1:
The receiving device automatically decodes the audio message and extracts authorization information without requiring manual text entry by the user. The system performs self-service by automatically processing the audio signal, identifying the authorization code, and completing the transaction verification, thereby eliminating time loss and errors associated with manual entry
Solution Approach 2:
The patent introduces an audio message as an intermediary carrier that transmits authorization information between the transmitting device and receiving device. This intermediary enables automatic information transfer, replacing the need for direct manual text entry and significantly reducing authorization time
3Reliability
If new devices with specialized technology are required for secure transactions, then security can be enhanced, but device complexity and cost increase
Solution Approach 1:
The patent makes the authorization system universal by enabling any audio-capable device to perform secure transaction authorization. The system does not require specialized hardware but utilizes the existing audio transmission and reception capabilities of common devices, thereby achieving enhanced security without increasing device complexity
Solution Approach 2:
The patent replaces the need for specialized secure hardware with a software-based audio processing system. By substituting mechanical/specialized hardware requirements with acoustic signal processing, the system achieves high security while maintaining compatibility with existing common devices

AI summary
Methods and systems for facilitating and authorizing electronic transactions with various devices and systems are disclosed. Embodiments of the present invention utilize audio messages to initiate, process and complete transactions between two or more parties, allowing users to efficiently and effectively enter into and complete financial transactions with businesses and other users. The need to utilize text-based entry as part of the verification process—an inefficient, error-prone and insecure authorization mechanism—is minimized and, in some embodiments, avoided altogether. Unlike recently developed authorization methods, embodiments of the present invention may be implemented using any number of existing devices including, analog or digital televisions, radios, smartphones, tablets computers, and other devices. Embodiments of the present invention may also be utilized to facilitate authorization for various other transactions including to access to an account, website or other locations, to accept or propose trades, to sign a legal or non-legal document, and to verify identity.
