Summary
This study presents a front-end authorization mechanism to improve hospital information system (HIS) security. It enhances access control without requiring major system redesign, making security upgrades more feasible.
Area of Science:
- Health Informatics
- Computer Science
- Information Security
Background:
- Hospital Information Systems (HIS) require robust authorization for secure data access.
- Implementing new authorization requirements in existing HIS often necessitates extensive and costly redesign.
- There is a need for security enhancements that minimize structural modifications to legacy systems.
Purpose of the Study:
- To develop and describe a front-end authorization mechanism for enhancing HIS security.
- To provide a solution for improving authorization without major system overhauls.
- To address the challenges of retrofitting enhanced security features into existing hospital information systems.
Main Methods:
- Development of a novel front-end authorization mechanism.
- Integration of the mechanism into an existing HIS.
- Evaluation of the mechanism's effectiveness in enhancing security without extensive system modification.
Main Results:
- The developed front-end mechanism successfully enhanced the security features of the existing HIS.
- The implementation avoided major structural modifications to the HIS.
- The solution demonstrated feasibility for upgrading authorization in legacy systems.
Conclusions:
- Front-end authorization mechanisms offer a viable approach to enhancing HIS security.
- This method allows for improved access control in existing systems with minimal disruption.
- The findings support the adoption of front-end solutions for practical HIS security upgrades.
