Abstract

An Electronic Health Record (EHR) is a standard collection of health data from the general population and patients that is electronically stored in a digital format. User authentication and data security are the key issues in distributing EHRs. For researchers, handling larger-scale data along with preserving the patient’s privacy has been an issue for a long duration. In data collection, storage, and distribution, the prevailing EHR suffers from data manipulation, delayed communication, and trust-less cooperation. Therefore, by utilizing Hospital id - Patient id Username – Public Private key Caesar Cipher Digit Folding BCrypt (HPU-PPCC-DF-BCrypt) and Correlation Coefficient based Elliptic Curve Cryptography (CCECC), an efficient Cipher Hash based user authentication, Hashed Access Policy verification along with Data Security was proposed. For engendering secure validates for authentication, HPU- PPCC is wielded. For changing the cipher text to hash code, DF-BCrypt is employed. By employing the hash codes generated by the Secure Hash Algorithm (SHA 512), the hash tree access structure is built for performing efficient authorization. The data is encrypted and decrypted by utilizing the CCECC for enhancing data security. The proposed method is compared to the current methodologies. As per experimental evaluation, the proposed method effectively secures EHR data.
