Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing devices face security challenges due to open standard-based wireless communication interfaces, which can lead to unauthorized data access and attacks, compromising device functionality and battery life.
Innovation Solution
A hearing device with a processing unit, memory unit, and interface that operates based on stored security settings, allowing for the receipt, verification, and update of new security settings, including a new hearing device key identifier, to ensure secure communication and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open standard-based wireless communication interface is used, then ease of operation and adaptability are improved, but security and reliability deteriorate due to unauthorized access and attacks
Solution Approach 1:
The patent implements preliminary security actions by establishing security settings and cryptographic key pairs before wireless communication begins. The hearing device is pre-configured with security parameters, and security settings are established prior to any data transmission, preventing unauthorized access from the outset
Solution Approach 2:
The patent introduces cryptographic keys and security settings as intermediaries between the hearing device and external devices. These security mechanisms mediate all wireless communications, verifying authenticity and encrypting data to prevent unauthorized access while maintaining open standard compatibility
2Adaptability or versatility
If security settings are updated remotely, then adaptability and maintenance capability are improved, but security and reliability may deteriorate if unauthorized updates occur
Solution Approach 1:
The patent implements feedback mechanisms where the hearing device verifies incoming security setting updates against established security criteria. The device provides feedback by accepting or rejecting updates based on cryptographic verification, ensuring that only authenticated and authorized updates are applied
Solution Approach 2:
The patent requires preliminary verification of update authenticity before applying security settings changes. Cryptographic signatures and authentication protocols are executed in advance of the actual update application, preventing unauthorized modifications
3Adaptability or versatility
If memory is writable by external devices, then ease of operation and adaptability are improved, but security deteriorates due to potential malicious writes
Solution Approach 1:
The patent introduces cryptographic authentication and security settings as intermediaries between external devices and the hearing device memory. All write operations must pass through this security layer, which verifies the authenticity and authorization of the writing device before allowing memory modification
