Light-Based Authentication for Mobile Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device transactions lack robust security, particularly when authenticating at ATMs or POS devices, and when communicating with secure backend servers, as they are vulnerable to breaches due to inadequate security measures.
Innovation Solution
A method for wireless information passing and authentication using light-based communication between devices, where a message is sent from a first device to a second device, verified through line-of-sight light pulses, and then confirmed by a secure server, ensuring secure access and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional text message or typed key authentication is used between mobile devices, then ease of operation is improved, but security is worsened due to vulnerability to breaches and unauthorized access
Solution Approach 1:
The patent replaces traditional mechanical input methods (typing keys on a keyboard or entering PINs at ATMs) with optical communication. Light-based communication transmits authentication data wirelessly between devices, eliminating the need for physical input that is vulnerable to skimming and visual detection. This substitution maintains ease of operation while dramatically improving security.
Solution Approach 2:
The patent introduces light as an intermediary medium for transmitting authentication information between devices. Instead of direct text message transmission or physical key entry, the system uses light pulses to carry authentication data, creating a secure channel that is difficult to intercept. The light-based intermediary provides a trusted transmission path that enhances security while maintaining operational simplicity.
2Adaptability or versatility
If mobile devices communicate with secure backend servers or other secure devices, then functionality is improved, but security is worsened because the mobile device may be compromised and expose the other device to security vulnerabilities
Solution Approach 1:
The patent replaces traditional wireless communication protocols (which can be intercepted or compromised) with light-based optical communication for authentication purposes. This substitution creates a secure channel that is harder to compromise, allowing mobile devices to communicate with backend servers and other secure devices while protecting against security vulnerabilities.
Solution Approach 2:
The patent performs preliminary authentication using light-based communication before establishing regular communication channels. By verifying device identity and authenticity through optical transmission first, the system ensures that only authenticated devices can establish communication, preventing compromised devices from exposing secure systems to vulnerabilities.
3Ease of operation
If ATMs or POS devices require PIN entry for authentication, then ease of operation is improved, but security is worsened due to skimmers and visual detection by nearby observers
Solution Approach 1:
The patent replaces physical PIN entry at ATMs or POS devices with light-based wireless authentication. Instead of requiring users to type their PIN on a keyboard that may have skimmers or be observed by cameras and microphones, the system uses optical communication to transmit authentication data securely, eliminating the vulnerability to skimming and visual detection while maintaining ease of use.
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
Enhances security by ensuring only devices in close proximity can communicate, reducing the risk of unauthorized access and breaches, particularly in public transaction environments.
Implementation Method 1
the message is sent back from the first device after the second device uses light-based communication to communicate the message from the second device to the first device
Data Source
AI summary
A secure server detects a login from a user originating from a first device. A second user-registered device is sent a message. The second device: translates the message into light-based communication that is captured by a camera of the first device, translates the message back into the original message, and sends the translated message to the secure server. The secure server authenticates the message and sends an indication to the first device that the second device is permitted to access the first device. In an embodiment, information passed between the first and second devices continue using light-based communications.
