Intelligent Continuous Authentication for DRM
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Streaming service providers face revenue losses due to account misuse such as password sharing and unauthorized access, necessitating additional security measures that can frustrate legitimate customers.
Innovation Solution
Implementing intelligent continuous authentication (ICA) for digital rights management (DRM), where a user device manages ICA instances associated with media files, requesting and verifying unique codes from a central management system to enable or disable media playback based on validity, and using location rules to authenticate playback devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional security mechanisms are implemented to prevent account misuse and password sharing, then revenue losses are reduced, but user experience deteriorates due to customer frustration
Solution Approach 1:
The system performs preliminary authentication by obtaining location information and verifying it against stored location data before allowing content access. This advance verification prevents unauthorized access while providing a seamless experience for authorized users, as the authentication happens automatically in the background without requiring user intervention.
Solution Approach 2:
The authentication system operates autonomously by automatically obtaining device location, comparing it with stored location information, and making access decisions without requiring user input. The system serves itself by managing the entire authentication process, from data collection to access control enforcement, eliminating the need for manual security checks that would frustrate users.
2Reliability
If DRM technologies are implemented to prevent unauthorized access to content, then content protection is improved, but user experience deteriorates due to unnecessary interruptions
Solution Approach 1:
The patent replaces traditional mechanical DRM authentication methods with a location-based authentication system. Instead of requiring manual code entry, device pairing, or complex verification procedures, the system uses geographic location data to automatically determine access rights. This substitution eliminates interruptions while maintaining robust content protection, as location verification happens seamlessly in the background.
3Reliability
If location-based authentication is implemented to verify device proximity, then unauthorized access is prevented, but system complexity increases
Solution Approach 1:
The authentication system leverages the device's existing location capabilities, which are already present in modern smartphones and tablets for other purposes like maps and navigation. By reusing this existing functionality for authentication, the system avoids adding complex hardware or software components. The same location sensor serves multiple functions, reducing overall system complexity while enabling robust access control.

AI summary
The concepts and technologies disclosed herein are directed to intelligent continuous authentication (“ICA”) for digital rights management (“DRM”). A user device can receive a notification that a media content playback device has requested playback of a media file that is protected by an ICA engine (“ICAE”) instance. The user device can request a unique code from the media content playback device. The user device can provide the unique code to an ICAE central management system associated with a media content provider that provides media content encompassed in the media file. The user device can determine, based upon a result provided by the ICAE central management system, whether the unique code is valid or invalid. The user device can instruct the ICAE instance to enable or disable the media file based upon whether the unique code is valid or invalid.
