Selective Caching of Personal Settings by Apparatus Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information security concerns arise when personal settings are cached on image forming apparatuses in public locations, as they are vulnerable to cyberattacks, compromising user data privacy.
Innovation Solution
An information processing system that authenticates users and determines which personal settings can be cached based on reliability information, allowing only secure settings to be saved on the apparatus, while discarding sensitive information to maintain security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal settings are cached on the apparatus, then user convenience is improved, but information security is compromised
Solution Approach 1:
The patent applies local quality by differentiating the caching behavior based on the apparatus type. Reliable apparatuses (e.g., personal devices) cache personal settings to improve convenience, while unreliable apparatuses (e.g., public devices) do not cache settings to maintain security. This selective approach allows the system to optimize for convenience where safe and prioritize security where risky.
Solution Approach 2:
The system changes the parameter of cache retention based on reliability assessment. When an apparatus is determined to be reliable, the cache retention parameter is set to true, allowing settings to be saved. When unreliable, the parameter is set to false, preventing caching. This dynamic parameter adjustment resolves the contradiction by adapting the caching behavior to the specific security context.
2Loss of time
If personal settings are downloaded and cached on all apparatuses, then repeated use convenience is improved, but vulnerability to cyberattacks increases
Solution Approach 1:
The system performs preliminary anti-action by assessing apparatus reliability before allowing cache operations. The server evaluates whether the apparatus is reliable (e.g., based on authentication credentials or device identification) and preemptively prevents caching on unreliable devices. This preliminary security check blocks potential cyberattack vectors before personal settings are cached, eliminating the vulnerability while preserving convenience for trusted devices.
Solution Approach 2:
The server acts as an intermediary between the user's personal settings and the apparatus cache. It mediates the caching decision by receiving apparatus reliability information, determining whether caching is safe, and instructing the apparatus accordingly. This intermediary layer filters out security risks while allowing beneficial caching operations, resolving the contradiction between time savings and security exposure.
3Ease of operation
If the apparatus caches personal settings, then user experience is improved, but data leakage risk increases in public locations
Solution Approach 1:
The patent applies local quality by making caching behavior location-dependent through reliability assessment. Apparatuses in controlled environments (e.g., personal offices) are marked as reliable and allowed to cache settings for improved user experience. Apparatuses in public locations are marked as unreliable and prohibited from caching, preventing data leakage risk. This spatially-aware approach resolves the contradiction by adapting caching to the security context of each location.
Solution Approach 2:
The system dynamically changes the cache enablement parameter based on the assessed reliability of the apparatus and its environment. When an apparatus is determined to be in a secure location, the caching parameter is set to enable storage of personal settings. When detected to be in a public or untrusted location, the parameter is set to disable caching. This parameter change strategy allows the system to optimize user experience in safe locations while preventing data leakage in risky locations.

AI summary
An information processing apparatus includes a processor configured to obtain personal settings of an authenticated user, identify, among the obtained personal settings on a basis of reliability information including information regarding a reliable apparatus, savable personal settings, which are to be saved to an apparatus that has requested authentication of the user, generate, on a basis of a result of identification, determination information indicating the savable personal settings, which are to be saved to the apparatus that has requested the authentication of the user, and cause a first apparatus to save the savable personal settings obtained on a basis of the determination information.
