Centralized Storage Service for Protected Content Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in transferring and duplicating protected content across media systems due to the need for licenses, which are not always located in the same directory as the content items, and different protection schemes require different treatments, making it costly and time-consuming to recreate a library of protected content.
Innovation Solution
A storage service is coupled to a network that receives a duplicate copy of the content and license directly from the content server, allowing users to access and share content without needing to understand protection schemes, and enabling secure access through login, password, or biometric controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually transfer protected content across media systems, then content can be accessed on multiple devices, but the process becomes complex and time-consuming due to license management and different protection schemes
Solution Approach 1:
The patent introduces a content server as an intermediary that automatically manages the transfer of protected content and licenses between media systems. Instead of users manually handling license files and protection schemes, the content server mediates the entire process, handling authentication, license generation, and content distribution automatically based on the destination device's capabilities.
Solution Approach 2:
The system enables self-service by allowing users to simply select content for transfer without needing to understand or manually manage the underlying license mechanisms. The content server automatically handles all technical details including license validation, protection scheme adaptation, and secure delivery, making the complex process transparent to the end user.
2Reliability
If users recreate protected content libraries by re-downloading from multiple content providers, then content can be restored, but the process becomes costly and time-consuming
Solution Approach 1:
The patent implements preliminary action by having the content server automatically backup protected content and licenses to a centralized storage location before any loss or corruption occurs. Users can request backup of their content libraries, and the server proactively stores copies with associated licenses, so when restoration is needed, the content is already prepared and can be quickly retrieved without re-downloading from multiple providers.
3Reliability
If licenses are stored separately from content items, then content protection is maintained, but transferring and duplicating content becomes difficult due to directory location requirements
Solution Approach 1:
The patent merges the content items and their associated licenses into a unified transfer package handled by the content server. Instead of requiring users to manually locate and transfer separate license files from specific directories, the server bundles content and licenses together, automatically managing their association and ensuring they arrive together at the destination device.
Solution Approach 2:
The content server acts as an intermediary that decouples the physical storage locations of content and licenses from their logical relationship. The server maintains the association between content items and licenses in its system, allowing it to transfer them together even though they may be stored separately on different servers or storage locations, eliminating the need for users to manually match directories.

AI summary
A method includes receiving content and a license to the content at a storage system, receiving a request from a user system for the storage system to send the content and license to the user system, and sending the content and license from the storage system to the user system. Another method includes requesting content and a license to the content, receiving the content and license at a user system, requesting from the user system that the content and license be sent to a storage system, and requesting from the user system that the storage system send the content item to a second user system. In one embodiment, code could be used to perform a method that includes requesting content and a license to the content from a content provider, storing the content and license at a user system and a storage system, and requesting that the storage system send the content to another user system.
