Solution Overview
Problem
Existing network service provision systems lack secure and controlled methods for transferring and using services across different access points, particularly when devices like scanners are shared, leading to potential unauthorized access to previous users' accounts.
Innovation Solution
An information processing device and system that employs a connection setting retaining unit, access permission retaining unit, and determining unit to ensure that service usage is restricted to access points set using a service usage setting tool, validating activation bits to differentiate between valid and invalid connection settings, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device allows connection to multiple access points without verification, then ease of operation is improved, but security and reliability deteriorate due to potential unauthorized access to previous users' accounts
Solution Approach 1:
The patent applies preliminary action by verifying whether a connection setting was created using the service usage setting tool before allowing service usage. The determining unit checks this in advance, and only if the verification passes does the service using unit proceed to use the service. This prevents unauthorized access before it can occur, resolving the contradiction between ease of operation and security.
2Reliability
If a device restricts service usage to only verified access points, then security is improved, but adaptability deteriorates due to limited access points
Solution Approach 1:
The patent introduces an intermediary mechanism - the determination of whether connection settings were created using the service usage setting tool - that mediates between security requirements and adaptability needs. This intermediary verification layer allows the system to securely expand access to multiple verified access points without compromising security, resolving the contradiction between security and adaptability.
3Reliability
If a device implements verification of connection setting origin, then security is improved, but device complexity increases due to additional determination steps
Solution Approach 1:
The patent applies universality by designing the determining unit and service using unit as integrated components within the information processing device. These units perform multiple functions: verifying connection setting origin, determining service eligibility, and controlling service usage - all within a unified system architecture. This reduces overall system complexity while maintaining security, resolving the contradiction between security and device complexity.

AI summary
An information processing device including: a connection setting retaining unit which retains a connection setting of a connection to an access point that relays communication to a network for each access point; an access permission retaining unit which retains a token for using a service provided by a server on the network; a determining unit which determines whether or not the connection setting is a connection setting having been set using a tool that enables the connection setting and a usage setting of the service to be set in a series of procedures; and a service using unit which uses the service using the token in a communication relayed by an access point related to a connection setting determined to be a connection setting having been set using the tool.
