Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a risk of unintended data transmission when multiple sink devices are in proximity, leading to potential unauthorized access to content intended for a specific sink device.
Innovation Solution
An information processing apparatus that outputs authentication key information and decides whether to allow a wireless connection based on input and output authentication key information, ensuring secure pairing and authentication between the source and sink devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to connect to nearby information processing apparatuses, then ease of operation is improved, but reliability deteriorates due to risk of unintended connection
Solution Approach 1:
The patent applies preliminary action by displaying authentication key information on the sink device before the actual data transmission begins. This allows the source device user to verify they are connecting to the intended device, preventing unintended connections while maintaining ease of wireless setup.
Solution Approach 2:
The patent implements feedback by providing visual authentication key information to the user during the connection process. This feedback mechanism allows users to confirm they are connecting to the correct device, thereby improving connection reliability without complicating the wireless connection process.
2Reliability
If authentication process is implemented to prevent unintended connections, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent uses copying by displaying visual authentication key information (such as QR codes or numeric strings) that represents the authentication data. This visual copy allows users to easily transfer or verify authentication information without complex manual entry procedures, maintaining security while reducing operational complexity.
Solution Approach 2:
The patent replaces manual authentication mechanisms with visual display-based authentication. Instead of requiring complex password entry or physical token exchange, the system displays authentication key information visually, allowing for simpler user interaction while maintaining connection security.
3Reliability
If authentication key information is displayed on the sink device, then connection security is improved, but loss of time increases due to additional authentication step
Solution Approach 1:
The patent applies partial action by implementing only the essential authentication display function rather than a complete authentication protocol. By displaying authentication key information visually, the system achieves sufficient security verification without requiring multiple authentication steps, thereby minimizing time loss while maintaining security.
