Anonymous Communication Control via Dynamic Anonymity Level Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anonymous communication systems fail to balance user anonymity with service provider requirements, leading to either inadequate user identification for necessary services or excessive information disclosure.
Innovation Solution
An anonymous communication system that includes a communication control apparatus, user terminal, service apparatus, and anonymous communication apparatus, which manage anonymous properties through user-granted information, service anonymous property information, and anonymous communication ability information to ensure both user anonymity and service provider requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If anonymous communication is applied to prevent user attribute abuse, then user privacy is improved, but service provider's ability to identify user for service provision deteriorates
Solution Approach 1:
The patent applies local quality by differentiating anonymous property levels based on service requirements. Different services have different anonymous property requirements (e.g., level 1 for basic anonymity, level 2 for strong anonymity), and the system selectively applies the appropriate level of anonymity to each service based on the service's identification needs, rather than applying uniform anonymity across all services.
Solution Approach 2:
The patent changes the parameter of anonymous property level dynamically. The communication control apparatus determines the appropriate anonymous property level by comparing service anonymous property information with user-granted information, and adjusts the anonymity level accordingly. This allows the system to maintain user privacy while providing sufficient identification capability when needed by changing the anonymity parameter based on service requirements.
2Object-affected harmful factors
If strong anonymous property is applied to maximize user privacy, then user anonymity is improved, but service provider's service provision capability deteriorates
Solution Approach 1:
The patent implements dynamics by making the anonymous property level adjustable and adaptive rather than fixed. The system dynamically determines the appropriate anonymity level based on real-time comparison of service anonymous property information and user-granted information. This allows the anonymous property to adapt to different service requirements, providing strong anonymity when needed but allowing service identification when necessary.
Solution Approach 2:
The patent applies preliminary action by having the communication control apparatus determine and set the appropriate anonymous property level before communication occurs. The apparatus compares service requirements with user permissions in advance and establishes the suitable anonymity level beforehand, ensuring that both user privacy and service capability are maintained from the start of communication.
3Adaptability or versatility
If weak anonymous property is applied to maintain service identification, then service provider capability is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent implements feedback by having the communication control apparatus continuously compare service anonymous property information with user-granted information to determine the appropriate anonymity level. This feedback mechanism ensures that the system maintains sufficient service identification capability while protecting user privacy by adjusting the anonymous property level based on actual service requirements and user permissions.
4Device complexity
If uniform anonymous property is applied to all communications, then implementation simplicity is improved, but service-specific requirements are not met
Solution Approach 1:
The patent applies segmentation by dividing the anonymous property into different levels (e.g., level 1, level 2) that can be selectively applied to different services. Instead of applying a single uniform anonymous property to all communications, the system segments the anonymity into multiple levels and selects the appropriate level for each service based on its identification requirements, thereby meeting service-specific requirements while maintaining manageable system complexity.

AI summary
In an anonymous communication system, an anonymous property which a service provider requires and an anonymous property which a user permits are assured. A communication control apparatus 100 controls access from a user terminal 200 to a service apparatus 300 via an anonymous communication apparatus 410 based on service anonymous property information indicating an anonymous property for a user required by a service provider in a service provided with the service apparatus 300, anonymous communication ability information indicating an anonymous property of anonymous communication which the anonymous communication apparatus 410 is able to carry out, and user-granted information indicating an anonymous property, for the user permitted by the user in communication between the user terminal 200 and the service apparatus 300.
