Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication systems (ID, password, credit card) are used, then ease of operation is maintained, but security and reliability deteriorate due to loss, forgery, and unauthorized use
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (physical credit cards, written passwords) with an optical authentication system using light emission and detection. The authentication terminal emits light containing authentication data, which is received by the mobile device's camera, eliminating the need for physical card presentation and improving security against forgery and loss.
Solution Approach 2:
The patent introduces light as an intermediary carrier for authentication data transmission. Instead of direct physical contact or wireless electromagnetic transmission, authentication information is encoded into light signals that bridge the authentication terminal and mobile device, providing a secure intermediate channel resistant to interception and forgery.
2Productivity
If credit card information is transmitted through magnetic strip or online systems, then transaction speed is improved, but vulnerability to forgery and information exposure increases
Solution Approach 1:
The patent replaces magnetic strip reading and online data transmission with optical light-based communication. Authentication data is encoded into light signals emitted by the authentication terminal and captured by the mobile device's camera, eliminating magnetic strip forgery vulnerabilities and reducing online information exposure risks while maintaining fast transaction processing.
Solution Approach 2:
The patent changes the physical parameter of data transmission from electromagnetic fields (magnetic strip, wireless networks) to optical light parameters. By encoding authentication data into light intensity, duration, or pattern variations, the system achieves secure transmission that is difficult to intercept or forge while maintaining rapid transaction speeds.
3Reliability
If light-based authentication is implemented, then security against forgery and loss is improved, but device complexity increases due to additional modules
Solution Approach 1:
The patent leverages the multi-functionality of existing mobile device components, particularly the camera, which serves both standard photography functions and light-based authentication reception. The authentication terminal's light emitter also serves dual purposes for illumination and data transmission, reducing the need for dedicated separate components and minimizing overall system complexity.
Solution Approach 2:
The patent enables the mobile device to perform authentication reception using its own built-in camera and processing capabilities without requiring external specialized hardware. The device uses its existing sensors and computational resources to decode light signals, making the system self-sufficient and avoiding additional complexity from external add-on devices.
4Adaptability or versatility
If traditional authentication methods are used, then compatibility with existing systems is maintained, but susceptibility to malicious transactions and hacking increases
Solution Approach 1:
The patent introduces light signals as an intermediary authentication channel that is incompatible with traditional hacking methods targeting magnetic strips or network protocols. The optical transmission medium creates a new authentication layer that existing malicious software cannot intercept or manipulate, providing inherent protection against known hacking techniques while maintaining compatibility through standardized light communication protocols.

AI summary
It is capable of authentication by transmitting through light emitted from a flash of a smart mobile according to foregoing solution of the problem, security and stability can be improved in comparison with other authentication systems such as an ID, a password and a public authentication which are necessary to a bank task, a personal authentication, an identity authentication and a transaction remittance. And, even if the smart mobile is lost or a stranger acquiring this are misappropriating, cryptography such as patterns cannot be solved thereby it is not available. Further, carrying is easy to use anywhere regardless of the place because the transaction is available using a flash equipped to the smart mobile.
