Optical Authentication via Random Visual Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device authentication methods, such as biometric and NFC-based systems, require additional hardware, increasing complexity and cost, and are vulnerable to interception and unauthorized access.
Innovation Solution
Implementing a random visual presentation displayed on the mobile device, which is optically captured to generate an authentication value, eliminating the need for specialized hardware and enhancing security by using a true or pseudo-random process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric or NFC hardware is added to mobile devices for authentication, then security is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces physical hardware-based authentication systems (biometric sensors, NFC chips) with an optical display-based authentication system. The mobile device displays visual authentication elements (barcodes, QR codes, visual patterns) that can be captured optically by another device, eliminating the need for specialized authentication hardware while maintaining security through cryptographic protocols and secure element integration
Solution Approach 2:
The patent creates visual copies of authentication data in the form of displayable graphical representations (barcodes, QR codes, patterns). These visual representations can be optically captured and transmitted to another device for verification, replacing the need for direct hardware-to-hardware communication while enabling secure authentication through optical copying of authentication elements
2Reliability
If traditional authentication methods are used, then security is provided, but vulnerability to interception increases
Solution Approach 1:
The patent implements dynamic authentication elements that change over time, including time-limited codes, animated visual patterns, and session-specific authentication data. These dynamic elements expire after use or after a predetermined time period, preventing replay attacks and interception-based authentication bypass attempts
Solution Approach 2:
The patent incorporates preliminary security measures including secure element isolation, cryptographic protection of authentication data, and controlled optical transmission parameters. The system pre-establishes secure communication channels and uses cryptographic protocols to prevent interception and unauthorized copying of authentication elements before they can be captured
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 method provides secure authentication without additional hardware, reducing the risk of interception and unauthorized access, as the random visual presentation is difficult to spoof and transmit securely via optical capture.
Implementation Method 1
a display device of the mobile device to optically present a random visual presentation
Data Source
AI summary
An operation at a mobile device is authenticated by using a random visual presentation displayed at the device for the authentication. The mobile device generates and displays the random visual presentation which is optically captured (e.g., by a camera) at a capturing device. The capturing device uses the captured random visual presentation to generate an authentication value (e.g., a hash) based on a defined security protocol. The authentication value is compared to an expected value and if the values match the mobile device executes the operation.
