Dynamic Subscriber Contact Card with Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems face challenges in maintaining up-to-date contact information for subscribers, as static information is difficult to change and update, leading to outdated records, and subscribers lack control over access to their information.
Innovation Solution
Combining static directory information with dynamic actionable information into a contact card, allowing users to define access control rules and enabling consistent representation across multiple applications, with the ability to update information automatically and control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static directory information is maintained for subscribers, then contact information can be stored and accessed, but the information becomes outdated and difficult to update
Solution Approach 1:
The patent transforms static contact information into dynamic information by introducing presence services that automatically update subscriber status, availability, and contact details in real-time. The system monitors and publishes changes without requiring manual intervention, making the information dynamic while maintaining ease of access.
Solution Approach 2:
The system enables subscribers to automatically update their own contact information through presence services and profile management features. Users can publish their availability, status changes, and contact details themselves without requiring administrator intervention, making the system self-updating and eliminating the need for manual administrative updates.
2Reliability
If administrators control access to subscriber information, then system security is maintained, but subscribers lack control over their own information
Solution Approach 1:
The patent segments information access control into multiple levels: system-wide administrative policies and individual user-specific preferences. Each subscriber can define granular access rules for different types of information (presence status, contact details, personal notes) and different user groups, allowing both centralized security management and individualized control.
Solution Approach 2:
The system applies different access control characteristics to different portions of subscriber information. Users can specify that certain information (e.g., presence status) is publicly accessible while other information (e.g., personal notes) remains private or accessible only to specific groups. This local differentiation of access rights satisfies both security requirements and user control needs.
3Loss of information
If contact information is updated frequently, then information remains current, but system complexity and administration burden increase
Solution Approach 1:
The patent implements feedback mechanisms where the presence service continuously monitors subscriber status and automatically publishes updates when changes occur. The system receives feedback from various sources (user actions, device status changes, network conditions) and automatically responds by updating contact information, maintaining current data without requiring complex manual update processes.
4Adaptability or versatility
If multiple applications access contact information, then information can be used across different services, but consistency and representation vary
Solution Approach 1:
The patent creates a universal contact information structure that can be accessed and utilized by multiple different applications and services. The standardized presence information format serves as a common interface that maintains consistency across diverse applications while allowing each application to utilize the information according to its specific needs, ensuring both versatility and stability.
Data Source
AI summary
Static user information such as address, title, phone number(s), email address(es) and dynamic user information such as location, calendar, current phone number(s), etc. are combined in a dynamically updateable subscriber contact card for publishing to other applications. The subscriber contact card also includes user defined access controls for restricting access to portions of the information by select users. Other applications provide services such as communication services based on up-to-date information through the subscriber contact card.
