NFC Chip Music Sharing Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The music industry faces challenges in allowing temporary sharing of digital music files while maintaining control over reproduction and distribution, as existing encryption systems do not provide a convenient method for sharing or purchasing shared music.
Innovation Solution
A method using near field communication (NFC) technology, where an NFC chip with a unique ID and purchase code pair is used to authenticate and register music files, allowing temporary streaming and purchasing of music files, with the NFC chip being housed in a protective form to facilitate physical exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption systems are used to prevent transfer of music files, then control over reproduction and distribution is improved, but convenience for temporary sharing and purchasing is worsened
Solution Approach 1:
The system segments the music distribution process into distinct functional components: NFC chips for identification, purchase codes for authorization, and server-based authentication. This segmentation allows different aspects of control and convenience to operate independently and harmoniously.
Solution Approach 2:
The patent introduces an intermediary authentication system that mediates between the encrypted music files and the users. The server acts as a trusted intermediary that verifies purchase codes and manages licensing, enabling convenient sharing while maintaining control without requiring direct encryption/decryption operations by end users.
2Ease of operation
If physical media exchange is used for music distribution, then ease of sharing is improved, but control over reproduction and distribution is worsened
Solution Approach 1:
The system creates a virtual copy of the physical media experience through NFC technology. The NFC chip contains a unique identifier that replicates the functionality of physical media identification without requiring actual physical transfer of copyrighted content, thus maintaining control while enabling sharing.
Solution Approach 2:
The patent replaces the mechanical system of physical media exchange with an electromagnetic field-based NFC system. This substitution maintains the simplicity of physical-like exchange (tapping devices together) while eliminating the limitations of physical media control and enabling digital rights management.
3Ease of operation
If digital music files are made easily reproducible, then convenience for users is improved, but control over distribution is worsened
Solution Approach 1:
The system performs preliminary authentication and authorization actions before enabling music file access. Purchase codes are validated and licensing is established in advance through server authentication, ensuring control is maintained before convenience is provided to the user.
Solution Approach 2:
The patent implements a feedback mechanism where the server continuously monitors and authenticates access requests. The system provides real-time feedback on licensing status and authorization, enabling convenient user access while maintaining ongoing control over distribution through centralized authentication.

AI summary
Methods for sharing and transferring music files using near field communication (NFC), which include receiving an NFC ID from an NFC chip using an NFC enabled device, authenticating the received NFC ID with a server system using the NFC enabled device, and upon authentication, permitting the NFC enabled device to temporarily stream or purchase music files.
