Solution Overview
Problem
Existing non-contact user authentication methods face challenges in transmitting authentication information from a storage medium to a user terminal device without a traditional interface, such as AUX terminals, and require a separate communication module for wireless connectivity, causing user inconvenience.
Innovation Solution
An authentication apparatus that stores authentication data and converts it into a sound wave signal using a randomly generated identification value, allowing for non-contact transmission via sound waves, eliminating the need for a separate communication module and enhancing security by using unique identification values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication information is transmitted through a wireless communication network interface (Wi-Fi or Bluetooth), then authentication data can be transmitted without a traditional interface, but a separate communication module is required and pairing time is increased causing user inconvenience
Solution Approach 1:
The patent replaces wireless communication modules (electromagnetic-based systems like Wi-Fi and Bluetooth) with an acoustic-based authentication system. The authentication apparatus converts authentication information into sound wave signals that can be captured by the terminal device's microphone, eliminating the need for separate wireless communication modules and reducing device complexity while maintaining contactless operation.
Solution Approach 2:
The patent enables the authentication apparatus to transmit data through a universal medium (sound waves) that can be received by any device with a microphone, rather than requiring device-specific wireless communication protocols. This multi-functional approach allows the same authentication mechanism to work across different terminal devices without requiring them to have specific communication modules.
2Ease of operation
If authentication information is transmitted through a wireless communication network interface, then authentication can be performed without contact, but pairing time is increased causing user inconvenience
Solution Approach 1:
The patent replaces complex wireless pairing procedures with a simple acoustic signal transmission. The authentication apparatus directly converts authentication information into sound wave signals that are immediately captured by the terminal device's microphone, eliminating the time-consuming pairing process associated with Wi-Fi and Bluetooth while maintaining contactless operation.
Solution Approach 2:
The patent performs the authentication information conversion to sound wave signals in advance and transmits it directly without requiring real-time pairing establishment. The authentication data is prepared and transmitted as a ready-to-use acoustic signal that can be immediately captured and processed by the terminal device, reducing the overall authentication time.
3Quantity of substance
If authentication information is stored in a storage medium, then authentication data is available, but transmission to terminal devices without traditional interfaces is not possible
Solution Approach 1:
The patent replaces traditional physical interface transmission (AUX terminals) and wireless communication module transmission with acoustic signal transmission. The authentication apparatus converts stored authentication information into sound wave signals that can be transmitted through air and captured by the terminal device's microphone, enabling compatibility with modern devices that lack traditional interfaces while preserving the stored authentication data.
Solution Approach 2:
The patent introduces sound wave signals as an intermediary medium between the authentication apparatus and the terminal device. This intermediary allows the authentication data to be transmitted from the storage medium through the air to the terminal device's microphone, bridging the gap between devices without traditional interfaces and enhancing transmission compatibility.
