Electronic Musical Instrument Subscription Sound Data Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical instruments are limited to using permanent-type sound data, restricting the use of subscription-type sound data, which are in increasing demand.
Innovation Solution
An electronic device connected to a server that stores management information for subscription-type data usage, allowing confirmation and permission for using subscription-type data based on user-specific allowability, with a communication system involving a communication device, a mobile terminal, and a server to facilitate seamless data access and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subscription-type sound data is stored in the electronic musical instrument, then the variety of usable sound data is improved, but the risk of unauthorized use and resource leakage increases
Solution Approach 1:
A server is introduced as an intermediary between the electronic musical instrument and the sound data storage. The server manages subscription-type sound data and authentication, allowing the instrument to access authorized data without storing it locally. This mediator enables versatile data access while preventing unauthorized use through centralized control.
Solution Approach 2:
The subscription-type sound data is extracted from the electronic musical instrument and stored externally on the server. The instrument only stores necessary authentication information and usage rights, separating the valuable data from the device. This extraction prevents resource leakage while maintaining access capability through authentication mechanisms.
2Reliability
If management information is confirmed with the server for each user, then the security and authorization control are improved, but the system complexity increases
Solution Approach 1:
User authentication and authorization information are prepared and confirmed in advance with the server before sound data usage. The system performs preliminary verification of management information, ensuring that only authorized users can access subscription-type data. This preliminary action simplifies subsequent data access operations while maintaining strong security.
3Adaptability or versatility
If permanent-type sound data is used only, then the device simplicity is maintained, but the functionality and user demand are limited
Solution Approach 1:
The electronic musical instrument is designed to support multiple types of sound data usage, including both permanent-type and subscription-type data. The system provides universal functionality to handle different data licensing models through a unified architecture that manages authentication, authorization, and data access for various data types without requiring separate complex systems.
Data Source
AI summary
An electronic device and a data usage method are provided. An electronic musical instrument confirms whether respective sound data stored in a timbre memory or a wave memory can be used or cannot be used based on management information acquired from a server. A sound data determined to be usable in the management information is validated so that it can be used for loading or writing. On the other hand, a sound data determined to be unusable in the management information is invalidated so that it cannot be used.
