Mobile Data Carrier Authentication via Induction and Radio Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for storing and distributing audiovisual data lack control for creators, as they do not allow for effective management of distribution and compensation for media content usage, leading to reduced financial returns and lack of ownership appreciation by consumers.
Innovation Solution
A method involving a mobile data carrier that uses electromagnetic induction to establish a first transmission channel for authentication, followed by a radio signal-based second channel for data streaming, ensuring physical presence and verified authorization, allowing creators to control distribution and usage tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If audiovisual data is stored on external servers or playback devices for easy accessibility and transferability, then consumer convenience is improved, but creator control over distribution and compensation is lost
Solution Approach 1:
The system segments the data storage and transmission process into distinct phases: authentication phase (via first transmission channel) and data streaming phase (via second transmission channel). This segmentation allows creator control mechanisms to be embedded in the authentication phase while maintaining convenience in the streaming phase.
Solution Approach 2:
The mobile data carrier acts as an intermediary device between the creator's control system and the playback device. It receives authentication data from the playback device, verifies authorization, and then enables or disables data streaming accordingly, thus maintaining creator control while allowing convenient access when authorized.
2Reliability
If a two-channel transmission system is implemented with authentication and data streaming separated, then security and creator control are improved, but device complexity increases
Solution Approach 1:
The system merges the authentication and data streaming functions into a single mobile data carrier device that handles both processes. The first transmission channel (for authentication) and second transmission channel (for data streaming) are integrated in the same device, reducing overall system complexity while maintaining the security benefits of separate channels.
Solution Approach 2:
The authentication process via the first transmission channel is performed as a preliminary action before enabling data streaming through the second channel. This preliminary verification step ensures authorization is confirmed before any data transfer occurs, simplifying the control logic by establishing a clear sequence of operations.
3Reliability
If electromagnetic induction is used for the first transmission channel to enable short-distance authentication, then physical presence verification is improved, but transmission distance is limited
Solution Approach 1:
The transmission system is segmented into two functional parts: the first transmission channel using electromagnetic induction for short-distance authentication (verifying physical presence), and the second transmission channel for data streaming. This segmentation allows each channel to be optimized for its specific purpose without compromise.
Solution Approach 2:
The system uses the mobile data carrier as a portable copy of the creator's authorization credentials. Instead of requiring direct connection to a centralized control system, the authorized playback device can authenticate with any mobile data carrier that holds the appropriate credentials, effectively copying the authorization function to a portable device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables creators to manage and track the distribution and consumption of their media content, ensuring appropriate compensation and ownership recognition, while maintaining the haptic experience of traditional storage forms.
Implementation Method 1
a first transmission channel is established between the data carrier and the playback device by means of an electromagnetic field emitted by the playback device via electromagnetic induction in the mobile data carrier
Implementation Method 2
the second transmission channel is established between the data carrier and the playback device, via which second transmission channel the data stream is transmitted from the data carrier to the playback device by means of a radio signal from a transmitting antenna of the data carrier
