Digital Rights Enforcement Across Multiple Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital rights management systems restrict digital content usage to a single device, limiting users who own multiple devices and wanting to access the same content across them.
Innovation Solution
A method and system for digital rights enforcement that determines access rights across multiple devices, revoking access from one device if the user attempts to download content on another device, using factors like usage history to select which device to revoke, and encrypting content before download.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital rights management restricts content to a single device, then digital rights protection is improved, but user accessibility across multiple devices deteriorates
Solution Approach 1:
The patent implements dynamic access right management where the system automatically adjusts authorized device lists based on usage patterns. Access rights are not static but change over time based on factors like frequency of use, recency of access, and device importance, allowing the system to adapt between protecting rights and enabling multi-device access
Solution Approach 2:
The system changes parameters by evaluating multiple factors (usage frequency, recency, device importance) to determine which devices to revoke from. By adjusting these evaluation parameters dynamically, the system balances digital rights protection with user convenience across multiple devices
2Reliability
If the system automatically revokes access from previous devices, then digital rights compliance is improved, but user convenience deteriorates
Solution Approach 1:
The system performs self-service by automatically evaluating usage patterns and making revocation decisions without requiring user intervention. The system monitors its own authorized device lists and autonomously determines which devices to revoke, reducing manual management overhead while maintaining compliance
Solution Approach 2:
The system uses feedback from usage patterns to automatically adjust access rights. By continuously monitoring how devices are used and feeding this information back into the authorization system, the system makes intelligent revocation decisions that comply with digital rights while minimizing disruption to user workflows
3Stability of the object's composition
If the system waits for concurrent downloads to complete before proceeding, then system stability is improved, but download speed deteriorates
Solution Approach 1:
The system implements periodic action by checking download status at intervals and proceeding with revocation when conditions are met. Rather than waiting continuously or blocking indefinitely, the system periodically assesses whether concurrent downloads have completed, providing a balance between stability and productivity

AI summary
There is provided a method and system for digital rights enforcement. The method includes: determining digital content requested by a user via a selected user device; determining digital rights associated with the digital content; reviewing the digital rights to determine access rights relating to authorized devices for the user; determining whether the user has exhausted the access rights; and if the access rights are exhausted: determining at least one use factor for each of the user's previously authorized user devices; determining a previously authorized user device on which to revoke access to the digital content based on the at least one use factor; and revoking access rights to the previously authorized user associated device; otherwise downloading the digital content on the selected user device. The system includes a content review module and a revoker module.
