Solution Overview

Problem

Current hearing devices primarily allow only manufacturer-defined functionalities, limiting third-party services and posing challenges in ensuring privacy and security compliance.

Innovation Solution

A method that includes an initialization procedure for third-party applications, requiring service certification through a manufacturer access service, ensuring user acceptance and hierarchical confirmation levels for secure and controlled access to hearing instrument services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If third-party services are allowed to access hearing instrument functions, then service versatility is improved, but security and privacy compliance becomes more difficult to ensure

Engineering Contradiction:
Improveservice versatilityVSAvoidsecurity and privacy compliance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a manufacturer access service as an intermediary between third-party applications and hearing instrument services. This mediator verifies service certifications, manages access permissions, and ensures compliance with security and privacy regulations while allowing third-party services to operate. The intermediary controls the interaction without preventing versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manufacturer control over hearing instrument services is maintained, then security and privacy compliance is improved, but third-party service access becomes more restricted

Engineering Contradiction:
Improvesecurity and privacy complianceVSAvoidthird-party service access
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements preliminary verification of service certifications by the manufacturer access service before granting access to hearing instrument services. Third-party applications must obtain certification in advance, demonstrating compliance with security and privacy requirements. This preliminary control mechanism enables manufacturer oversight while allowing pre-validated third-party services to access functions.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If service certification requirements are implemented for third-party applications, then security compliance is improved, but device complexity increases

Engineering Contradiction:
Improvesecurity complianceVSAvoidinitialization procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the service certification verification process from the hearing instrument itself and places it in a separate manufacturer access service. The initialization procedure retrieves certification information from this external service rather than embedding complex verification logic within the hearing device. This extraction reduces device complexity while maintaining security compliance through centralized certification management.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

There is provided a method of operating a hearing instrument (10, 11) to be worn by a user, comprising: defining a plurality of hearing instrument services and assigning to each hearing instrument service a service access confirmation level selected from a plurality of hierarchically structured service access confirmation levels; providing an access software platform for enabling third party service access to the hearing instrument services; providing at least one application program adapted to provide a third party service to the hearing instrument, each application program adapted to utilize the access software platform and at least one of the hearing instrument services; providing a manufacturer access service for approving or denying access to the hearing instrument for each of the application programs depending on whether or not approval for the respective service access confirmation level(s) has been previously obtained. An initialization procedure of each application program comprises the steps of: obtaining, by the application program, confirmation of the service access confirmation level(s) assigned to the hearing instrument service(s) used by the application program; submitting a service certification request for the hearing instrument service(s) used by the application program to the manufacturer access service, the service certification request including the obtained confirmations of the service access confirmation level(s) assigned to the hearing instrument service(s) used by the application program; checking, by the manufacturer access service, whether the service certification request includes all required confirmations of the service access confirmation level(s) assigned to the hearing instrument service(s) used by the application program, and, if so, transmitting a respective service certification to the application program or the access software platform; wherein the access software platform enables access to the hearing instrument service(s) to be used by the application program if the respective service certification has been received by the application program or the access software platform, respectively.
