Hearing Device Unencrypted Metadata Broadcast for External Mode Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adapting hearing devices, such as hearing aids, to external devices like multimedia systems are complex and lack security in data transmission, making it difficult to simplify the operation and ensure data sensitivity and authorization.
Innovation Solution
A method where a hearing device broadcasts a universally receivable, unencrypted metadata-containing information item, allowing external devices to automatically adjust their operating mode based on the received data, including audio signal processing parameters, without requiring user intervention, and optionally accessing encrypted data with proper authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hearing device transmits encrypted data for security, then data security is improved, but device complexity and user operation complexity increase due to authentication requirements
Solution Approach 1:
The data transmission is segmented into two distinct phases: first, unencrypted metadata transmission for device discovery and basic adaptation; second, encrypted data transmission only when explicitly requested and authorized. This segmentation allows the system to maintain security while preserving operational simplicity for basic functions.
Solution Approach 2:
Different security levels are applied to different data types: metadata (device type, capabilities) is transmitted unencrypted for ease of operation, while sensitive user data remains encrypted and is only decrypted/transmitted when explicit authorization is given. This local quality approach ensures security where needed without complicating overall operation.
2Adaptability or versatility
If the hearing device transmits all data for complete adaptation, then adaptability is improved, but data security deteriorates due to exposure of sensitive information
Solution Approach 1:
Data is segmented into metadata (safe to transmit unencrypted) and sensitive user data (requires encryption and authorization). The external device can adapt using metadata alone, while full adaptation requiring sensitive data maintains security through controlled encrypted transmission.
Solution Approach 2:
The external device performs partial adaptation based on unencrypted metadata without requiring complete user data. This partial action achieves sufficient adaptation for many scenarios while maintaining security, and full adaptation is available on-demand through authorized encrypted data transmission.
3Reliability
If manual configuration is required for data transmission, then data security is improved through user control, but ease of operation deteriorates due to user intervention requirements
Solution Approach 1:
Authorization preferences are configured in advance by the user through the hearing device interface. Once configured, the system automatically handles authorization decisions during data transmission without requiring real-time user intervention, combining preliminary user control with automatic operation.
Solution Approach 2:
The hearing device autonomously manages the authorization process based on pre-configured user preferences. When an external device requests sensitive data, the hearing device automatically checks authorization status and either grants or denies access without requiring real-time user input, enabling self-service operation with maintained security.
Data Source
AI summary
A method for transmitting information relating to a hearing device, in particular a hearing aid, to an external device. The hearing device is thereby placed in an immediate environment of the external device and the hearing device broadcasts a generally receivable, unencrypted first information item containing metadata about the hearing device and/or access data. The unencrypted first information item is received by the external device. The external device changes its operating mode directly or indirectly as a result of the first information item and continues to be operated with the modified operating mode.
