Group Management Server Dynamic Identity List Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, especially in IoT environments, the creation of empty groups without explicit member consent leads to authorization and data protection issues, as recipient lists disclose identities to non-joining individuals, compromising privacy.
Innovation Solution
A system and method for dynamic group data protection are implemented, where a group management server creates a Vertical Application Layer (VAL) group, announces its creation, registers members upon consent, shares member information only with registered members, and manages de-registration requests, ensuring data protection and privacy by controlling access to identity lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the group management server includes the recipient list in the announcement message, then the server can efficiently notify all potential members of the group, but the identities of recipients are disclosed to individuals who may not join the group, compromising privacy
Solution Approach 1:
The patent extracts the recipient list from the announcement message, separating the notification function from the identity disclosure. The announcement contains only group creation information, while the recipient list is maintained separately by the server and used only for targeted notifications to individuals who consent to join.
Solution Approach 2:
The server performs preliminary actions by maintaining the recipient list in advance but not disclosing it in the announcement. Individuals are notified separately and can consent to joining before being added to the group, preventing premature identity disclosure while still enabling efficient group creation.
2Ease of operation
If the system allows empty group creation without explicit member consent, then group formation is simplified and faster, but authorization and data protection issues arise as non-members can see recipient lists
Solution Approach 1:
The server acts as an intermediary between group creators and potential members. It maintains the recipient list securely, processes consent requests, and manages group membership transitions. This intermediary role simplifies the user interface while ensuring proper authorization controls are implemented.
Solution Approach 2:
The system dynamically transitions groups from empty state to populated state based on consent. The recipient list is dynamically updated as individuals consent to join, and membership information is dynamically shared only with authorized members, providing both ease of creation and security.
3Loss of information
If member information is shared with all recipients in the announcement, then transparency and information availability are improved, but data protection and privacy of registered members are compromised
Solution Approach 1:
The patent applies local quality by providing different information to different recipients based on their authorization status. Registered members receive full member information, while non-members receive no such information. The server selectively distributes information based on individual authorization levels.
Solution Approach 2:
The system creates selective copies of member information and distributes them only to authorized individuals. Instead of broadcasting the full recipient list to all announcement recipients, the server generates and sends targeted copies to registered members only, preserving information availability while ensuring data protection.

AI summary
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for providing data protection to members of a Vertical Application Layer (VAL) group is provided. The method includes creating, by a group management server, the VAL group based on a VAL group creation request from a VAL server, announcing, by the group management server, a VAL group creation information to at least one group management client from a plurality of group management clients, registering, by the group management server, at least one group management client as a VAL group member from a plurality of group management clients, and sharing, by the group management server, VAL group member information comprising an identity list with the at least one group management client.
