Watch Biometric Access Control for Confidential Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watch systems lack secure access control mechanisms, allowing unauthorized access to confidential data when the watch is stolen or lost.
Innovation Solution
A biometric access control system using a multispectral biometric skin sensor and processing unit to authenticate users based on skin characteristics, distinguishing between general and confidential data categories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is implemented for watch functions, then user identity verification is improved, but the risk of unauthorized access to confidential data increases when the watch is stolen or lost
Solution Approach 1:
The patent segments data into two categories: general data and confidential data. Different access control mechanisms are applied to each segment. Confidential data requires additional biometric verification beyond basic authentication, while general data remains accessible. This segmentation resolves the contradiction by ensuring that even if the watch is stolen, confidential data remains protected while maintaining normal access for legitimate users.
Solution Approach 2:
The patent implements preliminary biometric verification before allowing access to confidential data. The system performs authentication checks and biometric verification in advance before data access is granted. This preliminary action ensures that only authorized users can access confidential data even if the device is compromised, resolving the security concern while maintaining user convenience.
2Reliability
If multiple biometric verification steps are added for confidential data, then data security is improved, but system complexity increases
Solution Approach 1:
The patent applies different quality levels of security to different data types. Confidential data receives enhanced biometric verification and stricter access controls, while general data uses standard authentication. This local quality approach ensures strong protection where needed without unnecessarily complicating the entire system, resolving the contradiction between security and complexity.
3Measurement precision
If biometric skin sensor is used for authentication, then access control accuracy is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent integrates the biometric skin sensor into the existing watch structure to serve multiple functions: user authentication, data access control, and security verification. By making the sensor multi-functional, the patent justifies the added complexity through enhanced capabilities that benefit all users, not just a specific feature set, thereby improving ease of manufacture relative to the added functionality.

AI summary
The invention relates to a method for controlling access to at least one confidential datum (28), the access to which by a function of a watch (100) requires the wearer of the watch to be identified, the method comprising the following steps: - authenticating (9) the wearer of the watch (100) in order to allow access to the functions of the watch (100); - selecting (10) one of said functions of the watch requiring the use of at least one of said confidential data (28) or general data (31) archived in the memory element; - determining (12) the category to which said at least one datum required by the function belongs; - verifying (15) the identity of the wearer of the watch (100) on the basis of at least one piece of biometric information included in a portion of the wearer's skin if said at least one datum belongs to the category of confidential data (28); and - authorizing (27) the use of said at least one confidential datum by the function if the identity of the wearer of the watch has been verified.
