Terminal Device Biological Data Whitelist Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices lack adequate security measures to protect biological information, making it vulnerable when shared with applications, despite improving user convenience in accessing such data.
Innovation Solution
A terminal device with a first processing unit to acquire and store biological information, and a second processing unit that determines and outputs this data based on identification information and specifying information, ensuring only authorized applications can access and use the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biological information is made accessible to multiple applications to improve user convenience, then user convenience is improved, but security of biological information deteriorates
Solution Approach 1:
The patent segments the application ecosystem into trusted and untrusted categories by implementing a whitelist mechanism. The terminal device maintains a whitelist of authorized applications that are permitted to access biological information, while implicitly blocking all other applications. This segmentation allows controlled access to improve convenience while maintaining security through explicit authorization requirements.
2Adaptability or versatility
If all applications are permitted to access biological information, then adaptability is improved, but security deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring a whitelist of trusted applications before they attempt to access biological information. The terminal device proactively determines which applications are authorized to access sensitive data and stores this authorization information in advance. When an application requests access, the system checks against the pre-established whitelist, ensuring that only pre-approved applications can access biological information, thus maintaining security while enabling adaptability for authorized apps.
Data Source
AI summary
A terminal device configured to be able to communicate with a measuring device for measuring biological information includes a first processing unit executing the processing of a first application and a second processing unit executing the processing of a second application. The first processing unit stores biological information acquired from the measuring device. The second processing unit determines whether the second application is able to use biological information, based on specifying information for specifying an application able to use biological information and the identification information of the second application. When the second application is able to use biological information, the second processing unit reads out biological information from the biological information storage unit and outputs the read biological information.
