Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication systems, such as those using magnetic stripe cards, are susceptible to interference and loss, leading to security issues and inconvenience, particularly in self-service applications where personalized services are required.
Innovation Solution
An identification system that captures and compares motion trajectories generated by users, using an image sensor, storage unit, and processing unit to classify motion vector information, eliminating the need for magnetic stripe cards or passwords, and enhancing security through unique user patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic stripe cards are used for user authentication, then user identification can be achieved, but the system becomes susceptible to magnetic field interference and card loss
Solution Approach 1:
The patent replaces the mechanical magnetic stripe card system with an optical image recognition system. Instead of using magnetic fields and physical cards, the system captures images of users performing motion trajectories and processes these images through algorithms to identify users. This substitution eliminates susceptibility to magnetic field interference and card loss while maintaining authentication capability.
2Reliability
If passwords are required for authentication, then user identification can be achieved, but users may forget passwords causing access failure
Solution Approach 1:
The system captures motion trajectory images that naturally reflect each user's unique movement patterns. By analyzing these self-generated motion patterns rather than requiring users to recall passwords, the system provides authentication that is both reliable and convenient, eliminating the problem of forgotten passwords while maintaining security.
3Measurement precision
If motion trajectory images are captured and processed, then accurate user identification can be achieved, but system complexity increases
Solution Approach 1:
The patent segments the authentication process into distinct functional modules: image capture module, motion trajectory extraction module, feature analysis module, and user identification module. Each module performs a specific function, making the overall complex system manageable and maintainable while achieving high identification accuracy through specialized processing at each stage.

AI summary
The present invention discloses an identification system which includes an image sensor, a storage unit and a comparing unit. The image sensor captures a plurality of images of the motion trajectory generated by a user at different timings. The storage unit has stored motion vector information of a group of users including or not including the user generating the motion trajectory. The comparing unit compares the plurality of images with the motion vector information to identify the user. The present invention also provides an identification method.
