Personal Digital Identity Card with Motion Sensor Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Password-based cloud service authentication in mobile devices is vulnerable to hacking, as hackers can gain access to user accounts by obtaining password files, compromising sensitive user information.
Innovation Solution
A personal digital identity device that communicates with mobile devices and cloud services using radio links, requiring user interaction through hardware-based methods such as button presses, fingerprint sensors, or motion sensors to authenticate, making security hardware available only after user interaction, thereby enhancing security beyond password-only authentication.
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
Solution Approach 1:
The authentication system is segmented into two distinct components: a password input mechanism for ease of operation, and a separate hardware-based interaction device (such as a fingerprint sensor, motion sensor, or button) for security verification. This segmentation allows each component to optimize for its specific function while working together to provide both user-friendly operation and robust security protection against hacking attempts.
2Reliability
If hardware-based interaction device is added, then security is improved, but device complexity is worsened
Solution Approach 1:
A processor is introduced as an intermediary component that manages the interaction between the password input mechanism and the hardware-based interaction device. The processor receives inputs from both components, validates them according to configured authentication policies, and coordinates the authentication process. This intermediary approach allows the system to achieve enhanced security through multiple verification methods while maintaining manageable overall system complexity through centralized control logic.

AI summary
A personal digital ID device provides a digital identifier to a service for a predetermined duration in response to user interaction. The user interaction may include a button press. The personal digital ID device may be in the form of a bracelet, a key fob, or other form factor. The service may be provided by a mobile device, in the cloud, or elsewhere.
