VIN-Based DRM Provisioning for Vehicle Media Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management (DRM) systems face challenges in efficiently managing and distributing digital content across various devices, particularly in vehicles, where content access is restricted by device-specific DRM packages, leading to complexity in user authentication and content delivery.
Innovation Solution
A system and method that utilize a vehicle identification number (VIN) to create and manage DRM packages, allowing specific content to be streamed from a content provider to a vehicle's head unit via a mobile device, enabling secure and device-independent access control through an access control list.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-specific DRM packages are used to manage digital content access, then content security and access control are improved, but system complexity and user authentication complexity increase
Solution Approach 1:
The patent applies universality by using the vehicle identification number (VIN) as a universal identifier that works across all vehicle models and systems. Instead of creating device-specific DRM packages for each vehicle type, the system uses a single VIN-based approach that provides universal access control. The VIN serves as a universal key that can authenticate content access across different vehicles, eliminating the need for multiple device-specific DRM implementations.
Solution Approach 2:
The patent extracts the device-specific DRM package complexity from the content delivery system. By separating the DRM management function from the content delivery mechanism, the system uses VIN-based authentication as a standalone credential that simplifies the overall system. The DRM package is extracted and replaced with a simpler VIN verification mechanism that maintains security while reducing complexity.
2Reliability
If multiple device-specific DRM packages are created for different vehicles, then content access control is improved, but content distribution complexity increases
Solution Approach 1:
The system uses the VIN as a universal identifier that enables a single content distribution mechanism to work across all vehicles. Instead of creating separate distribution channels for different vehicle types, the VIN-based system provides universal access, allowing content to be distributed once and accessed by any vehicle with the matching VIN, thereby improving distribution efficiency.
Solution Approach 2:
The patent merges all device-specific DRM management functions into a single VIN-based authentication mechanism. By combining multiple separate DRM package management systems into one unified VIN verification system, the complexity of managing multiple packages is eliminated while maintaining access control capabilities.
3Ease of operation
If VIN-based DRM package association is used, then ease of content management and distribution is improved, but authentication security requirements increase
Solution Approach 1:
The system applies self-service by using the VIN, which is already a unique identifier that the vehicle system possesses, as the authentication credential. Instead of requiring external authentication services or complex security protocols, the system leverages the existing VIN data to provide self-contained authentication. The vehicle's own identification number serves as the security credential, eliminating the need for separate authentication infrastructure.

AI summary
Embodiments relate generally to systems and methods for provisioning vehicle based digital rights management (DRM) for content delivered through a brought-in mobile device. Content may be delivered by the content provider to the vehicle via connection with the mobile device, wherein the content may be accessed using a computer system (or head unit) in the vehicle. Access to the content may be controlled or managed using a DRM package associated with a vehicle identification number (VIN) of the vehicle.
