Reversible Identifier Converter for Secure Process Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems face challenges in uniquely and securely assigning identifiers to processes and data within document management systems, particularly in healthcare settings, where identifier uniqueness and security are critical for managing medical information.
Innovation Solution
An information processing apparatus comprising an identifier generator that produces uniquely specified first identifiers, and a reversible converter that transforms these identifiers into second identifiers, ensuring non-overlapping and secure assignment to processes and data, with the second identifiers being assigned through an assignment unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identifiers are assigned to processes and data in document management systems, then data tracking and management capability is improved, but the risk of identifier overlap and security vulnerabilities increases
Solution Approach 1:
The patent introduces a reversible conversion mechanism as an intermediary between the original identifier and the assigned identifier. This mediator (reversible converter) transforms the original identifier through encryption or hashing to generate a second identifier that cannot be easily reversed, preventing identifier overlap while maintaining data integrity and security
Solution Approach 2:
The patent changes the parameter state of the identifier by applying reversible conversion. The original identifier is transformed into a different format or representation (second identifier) through cryptographic functions, altering its parameters to ensure uniqueness and prevent overlap while allowing recovery when needed
2Measurement precision
If unique identifiers are generated for high-frequency transactions, then transaction tracking accuracy is improved, but the computational overhead and processing time increases
Solution Approach 1:
The patent performs preliminary action by generating and storing the reversible conversion relationship between the first and second identifiers in advance. This allows the system to quickly retrieve and use pre-computed identifier mappings during high-frequency transactions, reducing real-time computational overhead while maintaining tracking accuracy
3Object-affected harmful factors
If identifiers are made secure through reversible conversion, then data security is improved, but the complexity of the identifier management system increases
Solution Approach 1:
The patent extracts the security function into a separate reversible conversion module. This extraction allows the core identifier management system to remain simple while the security concerns are handled by the dedicated conversion mechanism, which can be implemented as a separate library or service that adds security without complicating the overall system architecture

AI summary
An information processing apparatus includes an identifier generator, a reversible converter, and an assignment unit. The identifier generator generates first identifiers which are uniquely specified. The reversible converter reversibly converts the first identifiers to generate second identifiers. The assignment unit assigns the second identifiers to processes to be assigned with identifiers.
