A New Supervision Strategy based on Blockchain for Electronic Health Records

According to Medical Statistics conducted in the USA, the number of patients who die every year from Medical errors are estimated to be around 200 to 400 thousand. The most common types of medical mistakes are (Billing errors, incorrect medication/incorrect dosage). Moving towards Electronic Health Records (EHR) instead of the paper-based system can prevent Medical errors. The (EHR) faces challenges regarding the issues of security and privacy. Utilizing blockchain can provide the proper solution to the above-stated challenges. This paper aims to introduce a new supervising strategy regarding accessing, sharing, and storing the (EHR). The proposed strategy enhances the security in a distributed network environment, through applying blockchain technology and hash table. Furthermore, it is applying a newly developed collision-resistant hash function in generating a unique ID for each patient in the EHR System. The Proposed scenario will improve the overall performance of the EHR system making it more efficient and reliable than the traditional system.
