Hearing Device Access Right Certificate System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hearing devices have secure architectures that limit access for software development and testing, making it difficult for developers to test software applications and for manufacturers to control access levels while maintaining security.
Innovation Solution
A hearing device with a processing unit that obtains and verifies access right certificates, granting specific access rights based on identifiers, allowing for secure testing and development while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hearing device uses a secure architecture to prevent unauthorized access, then security is improved, but access for software development and testing deteriorates
Solution Approach 1:
The patent segments access rights into different levels by introducing an access right certificate system with multiple certificate types. Each certificate type grants specific access levels (full access, limited access, no access) to development and testing functions, allowing the secure architecture to maintain security while enabling controlled access for software development and testing purposes.
2Reliability
If a hearing device manufacturer prevents access to unauthorized software, then security is improved, but the ability to test and run unauthorized software for development deteriorates
Solution Approach 1:
The patent introduces an access right certificate as an intermediary mechanism between the secure architecture and software testing needs. The certificate system acts as a mediator that allows authorized testing of unauthorized software by developers while maintaining security against malicious unauthorized access. The processing unit verifies certificates before granting access, enabling controlled testing without compromising overall security.
3Reliability
If a hearing device limits sharing of security material, then security is improved, but the ability to control access levels for different developers deteriorates
Solution Approach 1:
The patent applies local quality by making access rights specific and differentiated for different developers and devices. The access right certificate includes device-specific identifiers and developer-specific access levels, allowing the system to grant different access permissions (full access, limited access, no access) to different developers based on their needs and trust levels, while maintaining security through verified authentication.

AI summary
A hearing device includes: a processing unit configured to compensate for hearing loss of a user of the hearing device; and a memory unit; wherein the processing unit is configured to: obtain an access right certificate, the access right certificate comprising an access right identifier, verify the access right certificate, and if the access right certificate is verified, provide an access right according to the access right identifier.
