Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based authentication is used for cloud service access, then ease of operation is improved, but security is worsened due to vulnerability to hacking
Solution Approach 1:
A wearable identity device is introduced as an intermediary authentication component between the user and cloud services. This device stores credentials securely and requires physical possession plus user interaction (button press) to authenticate, thereby mediating the authentication process to enhance security while maintaining ease of use.
Solution Approach 2:
The authentication system is segmented into two separate factors: something the user possesses (the wearable identity device) and something the user does (presses the button). This segmentation ensures that both physical possession and active user interaction are required, preventing unauthorized access even if one factor is compromised.
2Reliability
If secure hardware authentication is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The wearable identity device merges multiple security functions into a single compact unit: secure credential storage, cryptographic operations, and user interaction detection (button press). This consolidation provides robust security without requiring multiple separate devices or complex system configurations.

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.
