Smartwatch Biometric Authentication for Confidential Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartwatches lack secure access control mechanisms, allowing unauthorized access to personal and confidential data even if the device is stolen, as authentication does not effectively differentiate between general and confidential data categories.
Innovation Solution
A method and system that utilize a multispectral biometric skin sensor, graphical representation, and processing unit to authenticate the wearer by verifying identity through biometric information, such as vascular networks or skin texture, and authorize access to confidential data based on category determination and verification steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods are used to grant access to watch functions, then ease of operation is improved, but security and reliability deteriorate as unauthorized users can access confidential data
Solution Approach 1:
The patent segments data into two distinct categories: general data accessible after basic authentication, and confidential data requiring additional biometric verification. This segmentation allows the system to provide different levels of access control based on data sensitivity, resolving the contradiction between ease of operation for general functions and security for confidential data.
Solution Approach 2:
The patent applies different authentication quality requirements to different data access scenarios. General data access requires standard authentication, while confidential data access requires enhanced biometric authentication (vascular pattern or skin texture verification). This local quality approach ensures that security measures are applied precisely where needed without unnecessarily complicating general operations.
2Ease of operation
If basic authentication is used for all data access, then ease of operation is improved, but measurement precision of user identity verification deteriorates
Solution Approach 1:
The patent implements a dynamic authentication system that adapts the verification method based on the data category being accessed. The system transitions from static basic authentication to dynamic biometric authentication (vascular network or skin texture analysis) when confidential data access is attempted, thereby maintaining operational simplicity for general tasks while achieving high precision identity verification when needed.
3Reliability
If enhanced biometric verification is implemented for confidential data access, then reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent embeds the biometric verification subsystem within the existing authentication framework. The vascular pattern or skin texture sensor is integrated into the watch structure, and the biometric verification process is nested as an additional layer within the standard authentication flow. This nesting approach enhances security for confidential data while minimizing the perceived complexity for users, as the enhanced verification is transparently integrated into the existing system architecture.

Function Achieved in This Case
Provides secure, reliable, and robust access control to confidential data on smartwatches by ensuring only the verified owner can access sensitive information, preventing unauthorized use even if the device is stolen.
Implementation Method 1
a multispectral biometric skin sensor (7) capable of acquiring images of a portion of skin of the wearer and of identifying at least one biometric information element comprised in said images
Implementation Method 2
verifying the identity of the wearer of the watch on the basis of an interaction between the wearer of this watch and a graphical representation included in said watch
Data Source
AI summary
A method controls access to at least one confidential datum archived in a memory element of a watch. The memory element includes general data and confidential data, the access to which by a function of the watch requires the wearer of the watch to be identified. The method includes authenticating the wearer to grant access to the functions of the watch, selecting one of the functions of the watch requiring the use of at least one of the confidential data or general data archived in the memory element, determining the category to which the at least one datum required by the function belongs, verifying the identity of the wearer based on an interaction between the wearer and a graphical representation included in the watch, and authorizing use of the at least one confidential datum by the function when the identity of the wearer has been verified.
