Confidentiality Level Determination for Data Processing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing devices lack an efficient mechanism to determine and manage the confidentiality level of processed data, which is crucial for ensuring data security and compliance with confidentiality requirements.
Innovation Solution
An information processing device that includes a processing-type accepting unit, a data accepting unit, and a data processing unit, which determines the confidentiality level of post-processing data based on predefined tables and executes additional processing accordingly, ensuring secure data handling and output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data processing is performed without confidentiality level determination, then processing speed and productivity are improved, but data security and confidentiality protection deteriorate
Solution Approach 1:
The patent applies preliminary action by determining the confidentiality level of data before processing operations are executed. The confidentiality level determination unit assesses the data's sensitivity in advance, and based on this assessment, the control unit pre-configures appropriate processing restrictions. This ensures that confidentiality protection measures are already in place before any potentially compromising processing occurs, thus maintaining data security without significantly impacting processing efficiency.
2Reliability
If strict confidentiality control measures are implemented for all data, then data security is improved, but processing flexibility and ease of operation deteriorate
Solution Approach 1:
The patent implements local quality by applying different confidentiality control measures to different data based on their specific confidentiality levels. Rather than imposing uniform restrictions on all data, the system assesses each data item's sensitivity and applies tailored processing rules accordingly. High-confidentiality data receives strict controls, while low-confidentiality data enjoys greater processing flexibility. This differentiated approach maintains data security while preserving operational efficiency and flexibility.
3Reliability
If comprehensive confidentiality assessment of processed data is performed, then data security is improved, but processing time and complexity increase
Solution Approach 1:
The patent extracts and isolates the confidentiality level determination function into a dedicated confidentiality level determination unit, separate from the main data processing workflow. This modular approach allows the confidentiality assessment to be performed efficiently as a distinct step, with results cached and reused for subsequent processing decisions. By separating the assessment function from the processing logic, the system minimizes the time impact on overall data processing while maintaining comprehensive confidentiality evaluation.

AI summary
An information processing device includes a processing-type accepting unit that accepts a type of first processing of data, a data accepting unit that accepts post-processing data, the post-processing data being data on which the first processing accepted by the processing-type accepting unit has been executed, and a data processing unit that determines a data confidentiality level indicating a degree of confidentiality of the post-processing data, on a basis of a first confidentiality level associated with the type of the first processing, and executes second processing according to the data confidentiality level with respect to the post-processing data.
