Security Enhancement to Exchange Health Information on Cloud

Abstract

The Electronic Health Record deployment at hospitals helps to improve patient safety and quality of care, but it has the prerequisite of interoperability between Health Information Exchange at different hospitals. The Clinical Document Architecture (CDA) document generation and integration Open API service based on cloud computing, through which hospitals are enabled to conveniently generate CDA documents without having to purchase proprietary software. CDA document integration system integrates multiple CDA documents per patient into a single CDA document and physicians and patients can browse the clinical data in chronological order. Along with achieving the interoperability, security is also a major concern. The proposed system provides security to the CDA document by making use of advanced encryption standard algorithm, RSA an asymmetric encryption algorithm and given to the patients for avoiding the interchanging and duplication of medical reports. Every detail in CDA Document is Encrypted and stored in Database. The proof for the efficient working of the proposed approach shall be given by ensuring reasonable quality of service even with multiple users logged on the system at the same time.
