Optical Mark Authentication for Secure Personal Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Password-based authentication methods are vulnerable to issues such as forgetting, stealing, or unintentional exposure, compromising the security of online transactions and personal data sharing.
Innovation Solution
A dynamic optical mark is displayed on a device screen, recognized via a personal mobile device's camera, and used for a verified mutually authenticated transaction with a time-limited one-time password, leveraging biometric authentication and hardware-encrypted storage for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based authentication is used, then ease of operation is improved, but security is worsened due to vulnerability to forgetting, stealing, or unintentional exposure
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with an optical mark recognition system. Instead of typing passwords, users scan optical marks displayed on the service provider's screen using their mobile device cameras. This substitution eliminates password vulnerability while maintaining ease of operation through simple scanning gestures.
Solution Approach 2:
The patent introduces an intermediary optical mark as a mediator between the user and the service provider. The optical mark is generated by the service provider, displayed on screen, scanned by the user's mobile device, and then verified. This intermediary mechanism transfers authentication credentials without exposing passwords, resolving the security-ease of operation contradiction.
2Reliability
If out-of-band optical mark recognition is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent leverages the universal capabilities already present in modern mobile devices - cameras for capturing optical marks and processors for recognizing patterns. By utilizing existing multi-functional components, the system achieves enhanced security without requiring specialized hardware, thus minimizing the increase in device complexity.
Solution Approach 2:
The system employs self-service mechanisms where the mobile device's camera and processing capabilities automatically handle optical mark capture and recognition. The service provider's system automatically generates and verifies marks without manual intervention. This automation reduces operational complexity despite introducing new security mechanisms.

Data Source
AI summary
Disclosed are methods and apparatuses for creating a verified mutually authenticated transaction between a service provider and an on-line identity for a physical client person. A dynamic optical mark may be displayed on a device screen where the physical client person is using a web service. The dynamic optical mark may be recognized via scanning the dynamic optical mark by a personal mobile device equipped with a camera. The verified mutually authenticated transaction between the service provider and the on-line identity for the physical client person may be used for sharing personal data of the physical client person by using out-of-band optical mark recognition of the dynamic optical mark. The verified mutually authenticated transaction may be initiated with a time-limited one-time password comprising a sequence of numbers encoded in the dynamic optical mark.
