Information Control Program for Secure Data Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for browsing and editing information on servers are complex and often require modifying application programs or installing new security programs, making it difficult to use existing applications securely without additional modifications.
Innovation Solution
An information control program that adds modifications to data transmission between operating systems and applications, including encryption, storage destination restriction, and decryption functions, allowing secure data handling without modifying existing applications or installing new security programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security countermeasures are implemented by changing control of application programs or operating systems, then security improvement is achieved, but application program compatibility deteriorates and installation complexity increases
Solution Approach 1:
The patent introduces an information control program as an intermediary layer between the operating system and application programs. This mediator intercepts and controls information transmission without requiring modifications to existing applications or OS control structures, thereby achieving security improvement while maintaining application compatibility and reducing installation complexity
Solution Approach 2:
The information control program operates autonomously by automatically adding predetermined modifications to transmitted/received information between the OS and applications. It self-manages security functions such as encryption, storage destination restriction, and decryption without requiring external intervention or complex system reconfiguration
2Reliability
If new security countermeasure programs are installed to improve security, then security countermeasure is enhanced, but ease of operation deteriorates due to additional installation and configuration requirements
Solution Approach 1:
The patent merges multiple security functions (encryption control, storage destination restriction, decryption) into a single information control program that operates transparently. This consolidation eliminates the need to install and configure multiple separate security tools, thereby enhancing security while simplifying operation and installation
3Ease of operation
If existing application programs are used without modification, then ease of operation is maintained, but security countermeasure capability deteriorates
Solution Approach 1:
The information control program serves as a mediator that enables security functionality to coexist with existing application programs without modifying them. It intercepts information flow at the OS-application interface, adding security controls while allowing applications to operate unchanged, thus maintaining compatibility while enhancing security

AI summary
Disclosed are programs, systems, and methods which are capable of using an application program previously used without modification and improving a security counter-measure when a data file is browsed and edited in a user terminal without installing a new security counter-measure program. An information control program has a function of adding a predetermined modification to transmitted/received information, which is transmitted and received between an OS and an application which is capable of generating a data file and saving the data file to an arbitrary information storage area. A save restriction function of restricting saving of the file not encrypted using a predetermined encryption key, a storage destination restriction function of restricting an area other than a predetermined area from being designated as the file storage destination, and a decrypting function of decrypting the file stored in the predetermined area using the predetermined encryption key are provided.
