Information Processing Device for Secure Data Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems lack the ability to conveniently and securely change the secrecy level and authorized disclosure parties of data, compromising both user convenience and data secrecy.
Innovation Solution
An information processing device and method that converts data into vectors in a latent space, displays the data as a graph, and allows users to specify changes to secrecy levels and authorized disclosure parties, with verification processing to ensure secure changes and proper data display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data secrecy is maintained at high levels, then data security is improved, but user convenience and accessibility deteriorate
Solution Approach 1:
The system dynamically adjusts data accessibility by allowing users to change secrecy levels and authorized disclosure parties based on real-time needs. The secrecy level and authorized disclosure parties are not fixed but can be modified through the information processing device, enabling the system to adapt between security and convenience requirements.
Solution Approach 2:
The system changes parameters related to data accessibility by allowing modification of secrecy levels and authorized disclosure parties. Users can alter these parameters to balance security requirements with operational convenience, transforming the static access control into a dynamic parameter adjustment mechanism.
2Ease of operation
If secrecy level is lowered or authorized disclosure parties are increased, then user convenience is improved, but data security deteriorates
Solution Approach 1:
The system incorporates verification processing that provides feedback to ensure secure changes. Before allowing secrecy level changes or authorized disclosure party modifications, the system verifies the user's identity and authorization, creating a feedback loop that prevents unauthorized access while maintaining convenience for authenticated users.
Solution Approach 2:
The verification processing acts as an intermediary between the user's convenience request and the actual data access change. This intermediary layer ensures that convenience improvements do not compromise security by validating the user's authority before permitting changes to secrecy levels or authorized disclosure parties.
3Reliability
If verification processing is added to prevent mistaken changes, then data security is improved, but system complexity increases
Solution Approach 1:
The verification processing enables the system to self-validate user identities and authorization levels automatically. Rather than requiring complex manual verification procedures, the system performs self-service verification to prevent mistaken changes, reducing operational complexity while maintaining security.
