Security Application for Streaming Media Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanaged networks, such as 3G and WiFi hotspots, pose challenges in content security and authentication for mobile devices, as they lack robust user/device authentication and are vulnerable to attacks like jail-breaking or rooting, leading to unauthorized access and difficulty in tracking user devices.
Innovation Solution
A security application on user devices manages access to streaming content by interacting with a registration server for authentication, a security server for access data, and a content server for playlist and content requests, using modified Uniform Resource Identifiers and multiple encryption keys to ensure secure playback, even on unmanaged networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is distributed over unmanaged networks to mobile devices, then user access flexibility and location independence are improved, but security and authentication control deteriorate
Solution Approach 1:
A security application acts as an intermediary component on the mobile device that mediates between the unmanaged network environment and the content protection system. This security application implements Conditional Access (CA) and Digital Rights Management (DRM) functionality directly on the device, enabling authentication and security control without relying on the network infrastructure to provide these services.
2Reliability
If device authentication and security features are implemented on mobile devices, then content security is improved, but device complexity and resource requirements worsen
Solution Approach 1:
The security application is designed to provide multiple security functions (authentication, encryption, key management, clone detection) within a single integrated software component. This multi-functional approach consolidates what would otherwise require multiple separate security modules, reducing overall device complexity while maintaining comprehensive content protection capabilities.
3Object-affected harmful factors
If security applications implement CA and DRM features on mobile devices, then unauthorized access prevention is improved, but processing overhead and energy consumption worsen
Solution Approach 1:
Authentication and security credentials are verified and established in advance before content delivery begins. The security application performs preliminary authentication checks, key establishment, and device verification prior to content playback, allowing the actual content streaming to proceed with minimal ongoing security processing overhead.
4Measurement precision
If two-way content protection systems collect device information, then clone detection capability is improved, but user privacy and data collection concerns worsen
Solution Approach 1:
The security application collects and analyzes device-specific information (hardware identifiers, software configurations, security state) locally on the device to create a unique security profile. This localized approach enables clone detection by comparing local device characteristics without requiring extensive centralized data collection or transmission of sensitive user information.
Data Source
AI summary
Systems and methods are disclosed that authenticate devices or users, and enable playback of secured streaming content through a media player. In one embodiment, the invention is a system for receiving secure content over an unmanaged network, including a security application configured operate on a user device with access to a network, where the security application is configured to receive a request for playlist data from the media player, send a playlist request to a content server, receive playlist data from the content server, send playlist data to a media player, receive a security access request from the media player, send a security access request to a security server, receive security access data from the security server; and send security access data to a media player.
