Centralized Privacy Server for Mobile Terminal Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling access to user information in mobile terminals are inconsistent due to separate access control systems in both the network and the terminal, leading to duplicate entries, lack of uniformity in service quality, and potential liability issues for operators.
Innovation Solution
A centralized system where a network-based privacy server stores access conditions, and a terminal-based security module receives and manages these conditions, ensuring uniform access control and reducing network overload by caching access permissions for subsequent requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate access control systems are implemented in both the network and the terminal, then access control functionality is provided, but duplicate entries of access conditions occur and service uniformity deteriorates
Solution Approach 1:
The invention extracts the access conditions from the terminal's local database and centralizes them in the network's privacy server. The terminal retains only a security module that references the centralized conditions, eliminating duplicate storage while maintaining access control functionality.
Solution Approach 2:
The invention merges the access control functionality into a single centralized system in the network, combining the privacy server and access conditions into one authoritative source. This consolidation eliminates the need for separate local copies in terminals, ensuring service uniformity across different manufacturers.
2Reliability
If separate access control systems are implemented in both the network and the terminal, then access control is provided, but service quality uniformity deteriorates
Solution Approach 1:
The invention creates a universal access control system in the network that serves all terminals regardless of manufacturer. The centralized privacy server provides multi-functional access control for different information types (location, contacts, availability) across diverse terminal implementations, ensuring consistent service quality.
3Reliability
If access conditions are stored in both network and terminal, then access control is maintained, but network load increases due to lack of caching
Solution Approach 1:
The invention performs preliminary action by having the terminal's security module cache or reference the access conditions from the network before actual access requests occur. This preliminary retrieval reduces subsequent network traffic for access control operations, lowering overall network load while maintaining reliable access control.

AI summary
A system for controlled access to information contained in a terminal (10) of a user of a telecommunications network (R). The system includes, in the terminal (10), an information server (11) adapted to supply said information; and in the network (R), a privacy server (20) in which conditions for access to said information defined by the user in said privacy server (20) are stored. The system further comprises a security module (12) in the terminal (10) adapted to receive said access conditions from the privacy server (20) at the time of a request to access said information.
