Information Processing Apparatus for Preventing Private Data Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public institutions face the risk of leakage of multiple types of private information when acquiring and processing data from external sources, which can lead to significant security breaches if such information is transmitted or printed simultaneously.
Innovation Solution
An information processing apparatus with a controller that prevents the simultaneous transmission or printing of multiple types of private information by identifying predetermined combinations and controlling the output, ensuring that only non-combined information is shared or printed, and notifying users of prohibited combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of private information are transmitted or printed simultaneously, then information sharing efficiency is improved, but information security deteriorates
Solution Approach 1:
The system performs preliminary analysis of information combinations before transmission or printing. The controller checks whether selected information types form prohibited combinations (e.g., personal information + financial information) and prevents output before the actual transmission occurs, thereby maintaining security while allowing legitimate information sharing
Solution Approach 2:
The controller acts as an intermediary between the information selection process and the output device. It intercepts the transmission/printing process, analyzes the combination of information types, and makes a go/no-go decision based on predefined security rules, thus mediating between efficiency and security requirements
2Adaptability or versatility
If all selected information is transmitted without restriction, then data accessibility is improved, but privacy protection deteriorates
Solution Approach 1:
The system segments information into different types (personal information, financial information, medical information, etc.) and applies different transmission rules to each type. By categorizing information, the system can selectively permit or prohibit transmission based on the specific combination of types, thus maintaining both accessibility and privacy protection
3Reliability
If combination checking is implemented, then information security is improved, but system complexity increases
Solution Approach 1:
The system establishes a predetermined list of prohibited information combinations in advance. During operation, the controller simply checks whether the selected information types match any entry in this pre-defined list, rather than performing complex real-time analysis. This preliminary preparation significantly reduces the computational complexity during actual information processing
Data Source
AI summary
An information processing apparatus includes a receiving unit and a controller. The receiving unit receives a selection of information which is to be output. The selection is selected from multiple types of information included in data obtained over a network and is based on each type. The controller exerts control in such a manner that, when the selected information includes multiple types of information constituting a predetermined particular combination, the selected pieces of information are not output.
