Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securely connecting a watch to a remote server are vulnerable due to the need for managing and storing numerous authentication elements, often in insecure environments, leading to security risks.
Innovation Solution
A method utilizing a watch equipped with a multispectral biometric skin sensor that captures images of the wearer's skin to generate a digital identification element based on vascular network or skin texture, which is then used for secure authentication with a remote server, eliminating the need for direct user intervention and reducing security vulnerabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication elements are stored on paper or in computer files, then ease of operation is improved, but security is worsened due to unprotected storage environments
Solution Approach 1:
The patent replaces mechanical storage methods (paper files, physical archives) with a biometric authentication system that uses the human body's biological characteristics. The skin sensor captures biometric data directly from the wearer's skin, eliminating the need for physical storage of authentication elements and thereby resolving the contradiction between ease of operation and security.
Solution Approach 2:
The system uses the wearer's own body (skin) as the authentication mechanism. The biometric data is extracted from the wearer's skin without requiring external storage devices or manual intervention. This self-service approach eliminates security vulnerabilities associated with stored authentication elements while maintaining ease of use.
2Adaptability or versatility
If multiple authentication elements are managed and stored, then adaptability is improved, but device complexity is worsened due to increased security risks
Solution Approach 1:
The patent employs a universal biometric authentication system that can access multiple authentication elements through a single skin sensor. The sensor captures biometric data that can be used for various authentication purposes across different services, eliminating the need for separate storage and management of multiple authentication elements while maintaining adaptability.
Solution Approach 2:
The skin sensor acts as an intermediary that extracts biometric information from the wearer's skin. This intermediary mechanism simplifies the system by providing a single access point for multiple authentication elements, reducing the complexity of managing and storing multiple credentials while maintaining versatility.
3Reliability
If biometric data is captured and processed, then security is improved, but measurement precision is worsened due to the need for accurate biometric extraction
Solution Approach 1:
The patent utilizes changes in electrical parameters (resistance, capacitance) of the skin to extract biometric information. By measuring these electrical parameters at different locations on the skin, the system achieves both high security through biometric authentication and sufficient measurement precision to accurately identify unique skin characteristics.
