Adaptive Security Scheme Switching for Image Processing Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in identifying the security scheme of an image processing apparatus without repeatedly transmitting inquiry information, especially when the security scheme is unknown.
Innovation Solution
An information processing system that transmits inquiry information according to a predetermined security scheme and, upon receiving a different security scheme response, adjusts to the same security scheme for successful communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inquiry information is repeatedly transmitted with different security schemes, then the security scheme of the image processing apparatus can be identified, but communication efficiency deteriorates due to multiple transmissions
Solution Approach 1:
The system performs preliminary action by transmitting inquiry information according to a predetermined security scheme before actual communication. When the image processing apparatus responds using a different security scheme, the operating terminal identifies this mismatch and proactively switches to the correct security scheme for subsequent communications, avoiding repeated trial-and-error transmissions.
Solution Approach 2:
The system uses feedback from the response information to identify the actual security scheme of the image processing apparatus. When response information is received according to a different security scheme than the predetermined one, this feedback indicates the correct security scheme to be used, enabling the terminal to adjust and maintain efficient communication.
2Adaptability or versatility
If the operating terminal switches security schemes dynamically, then compatibility with the image processing apparatus improves, but system complexity increases
Solution Approach 1:
The operating terminal implements dynamic security scheme switching based on the security scheme detected from the response information. The terminal transitions from using a fixed predetermined security scheme to a dynamic approach where the security scheme is adjusted according to the actual apparatus configuration, improving compatibility while maintaining manageable complexity through automated detection and adaptation.

AI summary
An information processing system includes a processor configured to: transmit inquiry information from an operating terminal of an information processing apparatus to the information processing apparatus according to a predetermined security scheme; and, upon receiving response information according to another security scheme different from the security scheme from the information processing apparatus, transmit the inquiry information to the information processing apparatus according to the same security scheme as the other security scheme.
