Content-Level Reactive Presence Authorization System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presence authorization mechanisms are limited in allowing reactive authorization of requested content, requiring modification of static rules, indirect authorization processes, and lack direct request capabilities, leading to persistent blocking of unauthorized content and inability for one-time authorization without affecting static rules.
Innovation Solution
Implementing a Content-level Reactive Presence Authorization system that allows Presentities to dynamically authorize requested content without modifying static rules, enabling direct authorization requests and specifying conditions for authorization, using new event packages and XCAP operations to manage Presence Authorization Rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reactive presence authorization is implemented by modifying static Presence Authorization Rules in Presence XDMS, then authorization flexibility is improved, but device complexity and operational burden increase
Solution Approach 1:
The patent segments the authorization rule into two independent parts: a static Presence Authorization Rule stored in Presence XDMS that defines general authorization policies, and a dynamic Reactive Presence Authorization Rule that handles specific content-level authorizations. This segmentation allows the system to maintain flexibility for reactive authorization while keeping the static rules simple and manageable, thereby reducing overall system complexity.
Solution Approach 2:
The patent introduces a Presence Server as an intermediary component that mediates between the static Presence Authorization Rules and the dynamic reactive authorization requests. The Presence Server receives reactive authorization requests, processes them against the static rules, and generates appropriate responses without requiring direct modification of the static Presence XDMS storage. This intermediary approach simplifies the system architecture by centralizing the authorization logic in the Presence Server.
2Reliability
If reactive presence authorization requires indirect authorization processes through Presence Server notifications, then authorization control is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by having the Presence Server proactively send NOTIFY messages to the Presentity containing information about pending subscription requests and protected content before the Presentity needs to make authorization decisions. This allows the Presentity to be pre-informed of the situation and make authorization decisions more quickly, reducing the overall time loss in the authorization process.
Solution Approach 2:
The patent establishes a feedback mechanism where the Presence Server sends NOTIFY messages to the Presentity about the status of subscription requests and protected content, and the Presentity responds with authorization decisions. This feedback loop ensures that the Presentity is kept informed of the current state and can make timely authorization decisions, improving both reliability and reducing time loss.
3Adaptability or versatility
If static Presence Authorization Rules are modified for reactive authorization, then content delivery flexibility is improved, but manufacturing precision (rule management precision) deteriorates
Solution Approach 1:
The patent segments the authorization rule into two independent parts: a static Presence Authorization Rule stored in Presence XDMS that defines general authorization policies, and a dynamic Reactive Presence Authorization Rule that handles specific content-level authorizations. This segmentation allows the system to maintain flexibility for reactive authorization while keeping the static rules simple and manageable, thereby reducing overall system complexity.
Solution Approach 2:
The patent applies local quality by making the reactive authorization rule specific to particular content items and situations, while keeping the general static authorization rules unchanged. The reactive rule is locally applied only when needed for specific content delivery scenarios, allowing flexible content delivery without affecting the precision and manageability of the general static rules.
4Ease of operation
If one-time authorization is implemented without affecting static rules, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent introduces a Presence Server as an intermediary component that mediates between the static Presence Authorization Rules and the dynamic reactive authorization requests. The Presence Server receives reactive authorization requests, processes them against the static rules, and generates appropriate responses without requiring direct modification of the static Presence XDMS storage. This intermediary approach simplifies the system architecture by centralizing the authorization logic in the Presence Server.
Solution Approach 2:
The patent implements dynamics by creating a flexible authorization mechanism where the reactive presence authorization rule can be dynamically created, modified, and deleted without affecting the static Presence Authorization Rules. The reactive rule is temporary and applies only to specific content delivery scenarios, allowing one-time authorization operations while maintaining the stability of the static rules. This dynamic approach increases ease of operation without requiring complex changes to the underlying static rule system.

AI summary
Disclosed is a new system and method for the "Content-level Reactive Presence Authorization", wherein the Presentity would be able to reactively authorize the Watcher requested contents of the Presentity' s Presence Information. According to the system and method for the Content-level Reactive Presence Authorization, it is possible for the Presence Server to convey the identity of the Watchers and the protected contents to the Presentity on the states of the Watcher's requested contents of the Presence Information. According to the systems and methods, it is also possible for Presentity to specify the conditions when the Presence Server triggers such Content-level Reactive Presence Authorization.
