Security Level Determination for Video and Audio Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When providing video or audio services over networks, there is a concern about unintended disclosure of confidential information due to unknown security conditions at the user's location, as existing technologies do not effectively determine the security level of the usage location before transmitting sensitive content.
Innovation Solution
An information processing apparatus that determines the security level of a user's surroundings by analyzing image and audio data to decide whether to perform video or audio transmission, using a processor with a security determination unit that includes image and audio determination units to assess the enclosure and noise levels, and a measure providing unit to adjust settings or restrict transmission if the security level is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video or audio transmission is performed without determining the security level of the usage location, then service accessibility and user convenience are improved, but the risk of unintended disclosure of confidential information increases
Solution Approach 1:
The system performs preliminary determination of the usage location and security level assessment before allowing video or audio transmission to occur. The processor determines the usage location based on location information, calculates the degree of risk, and only permits transmission when security conditions are satisfied, preventing information leaks before they can happen.
Solution Approach 2:
The system continuously monitors the usage location and security conditions, providing feedback to the transmission control mechanism. When the determined location and security level meet the transmission conditions, the system permits video or audio transmission; otherwise, it restricts transmission, creating a closed-loop security control system.
2Reliability
If the system determines the usage location and security level before transmission, then information security is improved, but the complexity of the system increases
Solution Approach 1:
The information processing apparatus integrates multiple functions into a single system: location determination, security level calculation, transmission condition evaluation, and transmission control. This multi-functional approach consolidates what could be separate complex systems into one unified apparatus, managing complexity while maintaining security.
Solution Approach 2:
The system uses parameter-based security control by calculating a degree of risk based on location information and comparing it against transmission conditions. This parameter-driven approach simplifies the security determination process by transforming complex security assessments into comparable numerical or logical parameters.
3Object-affected harmful factors
If the system restricts transmission based on security assessment, then the risk of information leak is reduced, but service availability may be compromised
Solution Approach 1:
The transmission control mechanism dynamically adjusts service availability based on real-time security assessment. When the usage location and security level satisfy transmission conditions, the system permits transmission and maintains high service availability. When conditions are not met, transmission is restricted to prevent information leaks, creating a dynamic balance between security and availability.

AI summary
An information processing apparatus includes a processor configured to obtain user's surroundings at a usage location where the user uses a service accompanied by communication with another location, determine, based on the obtained surroundings, a security level at the usage location for transmission of a video from the other location to the usage location or a security level at the usage location for transmission of an audio from the other location to the usage location, and determine, based on a determined level, whether to perform video or audio transmission between the usage location and the other location.
