Authorized Domain Creation via Device Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authorized domain systems either restrict users to specific devices or require person identification, limiting flexibility and convenience in accessing content across different environments.
Innovation Solution
A method for creating an authorized domain that associates a device with a second person, allowing them to exercise rights granted to the first person, without explicit domain management, using a device that can prove its trustworthiness and compliancy, and binding users to the domain rather than devices and content items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device based authorized domains are used, then content protection is achieved, but user flexibility is limited as users are restricted to a particular set of devices
Solution Approach 1:
The patent introduces an authorized domain as an intermediary layer between the user and the devices. Instead of directly binding users to specific devices, the system creates a domain that can encompass multiple devices. The domain acts as a mediator that allows users to access content across different devices while maintaining protection, thus resolving the contradiction between content protection and user flexibility.
2Ease of operation
If person based authorized domains are used, then user identification is simplified, but additional complexity is introduced through person identification requirements
Solution Approach 1:
The patent extracts the person identification requirement from the core domain creation process. Instead of requiring explicit person identification to create a domain, the system allows domains to be formed based on device associations. Person identification is taken out as an optional rather than mandatory element, simplifying the overall process while still allowing for user-specific control when needed.
3Reliability
If explicit domain management is implemented, then domain control is precise, but user convenience is reduced due to complex management procedures
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically manages domain creation and updates based on device associations. When a user associates devices or moves between devices, the authorized domain is automatically created or updated without requiring explicit user management actions. This maintains precise domain control through automatic device binding while significantly improving user convenience by eliminating complex management procedures.

AI summary
This invention relates to a method (100) for creating, on a device (200), an authorized domain (102) for sharing a (103) of a content item (104) between a first person (105) and a second person (106). The method (100) alleviates the hassle of having end-users managing authorized domains. If the first person is bound (107) to the right (103), and the device is bound (108) to the first person (105), the device (200) grants (110) the second person (106) the right (103) in response to the device (200) associating (109) to the second person (106).
