Template-Based Subscription Server for Role-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing publish-subscribe systems lack effective access control mechanisms, scalability, and efficiency, making them unsuitable for enterprise applications, particularly in ensuring secure and targeted notification of information to authorized users.
Innovation Solution
The implementation of a subscription server that uses subscribable objects with defined attributes and access controls, allowing users to subscribe based on predefined templates and user roles, and employing a communication flow expression to manage notification delivery, ensuring only authorized users receive relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional publish-subscribe systems are used, then notification delivery is simple, but security and access control are insufficient
Solution Approach 1:
The patent segments the subscription system into distinct components: templates define the structure and attributes of subscribable objects, access control mechanisms filter notifications based on user roles and permissions, and the publish-subscribe core handles message delivery. This segmentation allows security features to be added without overwhelming system complexity.
Solution Approach 2:
The patent implements preliminary action by pre-defining templates with required and optional attributes, and pre-configuring access control rules and user roles before actual subscription and notification operations. This preparation work establishes security frameworks in advance, making the system more secure without increasing operational complexity.
2Adaptability or versatility
If fixed taxonomies of topics are used, then system structure is simple, but adaptability to different user roles and enterprise applications is limited
Solution Approach 1:
The patent creates a universal template-based framework that can accommodate multiple user roles, subscription types, and enterprise applications through a single unified structure. Templates define subscribable objects with configurable attributes that can be reused across different contexts, making the system adaptable without requiring separate fixed taxonomies for each application.
Solution Approach 2:
The patent introduces dynamics by allowing templates and their attributes to be configured and modified based on different user roles and application requirements. Rather than fixed static taxonomies, the system dynamically adapts the structure of subscribable objects and their attributes to match the needs of different enterprise applications and user perspectives.
3Productivity
If all users receive all notifications, then information completeness is high, but efficiency and targeted delivery are reduced
Solution Approach 1:
The patent applies local quality by customizing notification delivery for different user roles and individuals through access control mechanisms. Each user receives notifications filtered according to their specific role, permissions, and subscribed templates, ensuring they get precisely the information relevant to their local context rather than a uniform broadcast to all users.
Solution Approach 2:
The patent implements feedback loops where the system monitors which users subscribe to which templates and adjusts notification delivery accordingly. This feedback mechanism ensures that information is delivered efficiently to the right users while maintaining completeness for those who have explicitly indicated interest through their subscriptions.
Data Source
AI summary
Methods and apparatus are disclosed for notifying one or more users of information, where the information has a plurality of attributes. A plurality of subscribable objects are provided to one or more of the users, where each of the subscribable objects comprises one or more of the plurality of attributes as required attributes and zero or more of the attributes as optional attributes. Subscription requests are received from one or more of the users based on at least one of the subscribable objects. The plurality of subscribable objects are based, for example, on a set of predefined templates. The predefined templates identify each of the plurality of attributes as a required attribute or an optional attribute. Each of the attributes is presented to a user using a display format selected based on a cardinality of the corresponding attribute. For example, the display format for a given attribute may comprise one or more of a user entry, a scrollable list and a check box.
