Content Delivery Bookmarks for Cross-Device Rights Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often lose the ability to finish consuming content due to interruptions, such as leaving a movie theater or an airplane flight before the content completes, resulting in the loss of access rights.
Innovation Solution
A content delivery system that monitors consumption and generates a content access bookmark to allow users to transfer content rights to another device, providing access information and decryption keys for missed content segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content access rights are limited to a single location or device, then security and control are improved, but user convenience and accessibility deteriorate
Solution Approach 1:
The content access rights are segmented into location-specific permissions and device-specific permissions. The system tracks whether the user is at the authorized location (e.g., movie theater) and whether the device is registered, allowing flexible combination of these segments to grant or deny access based on multiple independent criteria.
Solution Approach 2:
The access control system is dynamic rather than static. It continuously monitors location data, device identifiers, and content rights to determine whether to grant access in real-time. The system adapts its decisions based on changing conditions such as user movement between locations or device registration status.
2Ease of operation
If content rights are made portable across devices, then user convenience is improved, but system complexity and security risks worsen
Solution Approach 1:
A content delivery system acts as an intermediary between the user's portable device and the content source. This intermediary manages the complexity of rights verification, location monitoring, and access control decisions, shielding the user from system complexity while enabling portable access.
Solution Approach 2:
The system creates a copy of the content access rights associated with the user's portable device. Instead of transferring actual content, it copies the authorization metadata (including location constraints and device identifiers) to the new device, enabling access without duplicating the content itself.
3Ease of operation
If the system monitors user location and device to enable rights portability, then content accessibility is improved, but data processing requirements and system resources worsen
Solution Approach 1:
The system performs location monitoring and device verification only when necessary - specifically when a user attempts to access content on a different device or location. Rather than continuously processing all possible scenarios, it acts partially on actual access requests, reducing overall processing resource consumption.
Solution Approach 2:
The system performs preliminary actions by pre-establishing device registration and location context before actual content access is needed. This allows faster decision-making during actual access requests, as the monitoring and verification processes have already been partially completed in advance.
Data Source
AI summary
The system and methods described allow a content delivery application to provide temporary access to a content item for display on a content access device based on a user obtaining access to the content item initially on another system. The content delivery application receives content accessed confirmation that user access a content item and then monitors whether that access was interrupted. If the access was interrupted, the content delivery application generates a content access bookmark based on a content timeline and stores a content access authorization comprising the content access bookmark and an identifier from the profile. When the user requests the content item, the content delivery application transmits access information corresponding to segments of the content item, based on the content access bookmark to a user's device.
