Communication Terminal Security Assessment via Positional Risk Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems lack the ability to assess and ensure secure environments for video-conferences, particularly in public places, as they do not consider the positional information of communication terminals, leading to potential security risks.
Innovation Solution
A communication system comprising a call management server and a positional information server that updates and shares positional information and information leakage risk data among communication terminals, allowing terminals to display this information differently based on risk levels, enabling users to assess security before initiating a video-conference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication systems are used without positional information assessment, then communication can be initiated freely and easily, but security risks increase due to inability to assess communication environment
Solution Approach 1:
The patent introduces a positional information server as an intermediary component that collects, manages, and provides positional information about communication terminals. This server acts as a mediator between the communication system and security assessment requirements, enabling security evaluation without fundamentally redesigning the entire communication system. The server receives positional information from multiple sources (GPS, base station, access point) and processes it into usable security assessment data.
Solution Approach 2:
The system performs preliminary security assessment by obtaining and evaluating positional information before communication is initiated. The communication terminal requests positional information from the positional information server prior to starting video conferencing, allowing users to assess security risks in advance and make informed decisions about whether to proceed with communication.
2Reliability
If positional information and risk assessment are integrated into the communication system, then security assessment capability is improved, but system complexity and information processing requirements increase
Solution Approach 1:
The patent extracts the positional information management function into a separate positional information server, isolating the complex information processing requirements from the core communication system. This extraction allows the communication terminal to focus on its primary function while delegating positional information acquisition and processing to a specialized server, thereby reducing the information processing load on individual terminals.
Solution Approach 2:
The system implements feedback mechanisms where the communication terminal continuously monitors positional information and security risk levels, and adjusts its communication behavior accordingly. The terminal can receive updates on positional information and use this feedback to make real-time decisions about communication security, such as warning users or preventing communication initiation in high-risk locations.
3Loss of information
If the system displays detailed positional information and risk levels, then user awareness of communication environment is improved, but ease of operation decreases due to additional information management requirements
Solution Approach 1:
The patent applies local quality by providing differentiated information display based on specific communication scenarios and user needs. The system can display detailed positional information, risk levels, and environmental context in situations where security assessment is critical, while offering simplified interfaces for routine communications. The information display adapts to the local context of each communication request, providing appropriate levels of detail without overwhelming users in all situations.
Data Source
AI summary
A communication system includes a call management server; communication terminals; and a positional information server. The positional information server stores therein positional information and information leakage risk information of each communication terminal, updates the positional information and the information leakage risk information in accordance with a position of the communication terminal, and transmits the updated information together with corresponding communication terminal information to the call management server. The call management server updates the positional information and the information leakage risk information of a communication terminal when receiving the information from the positional information server, and transmits a list containing at least a terminal name, latest positional information, and latest information leakage risk information of each communication terminal capable of joining the communication to a communication terminal. The communication terminal displays the list in a different manner of the positional information in accordance with the information leakage risk information.
