Abstract

When compared to old paper record systems, privacy concerns are likely the most significant impediment to the adoption of electronic health record (EHR) systems, which are regarded as more efficient, less error-prone, and more available. Patients will not accept the EHR system unless the security of the healthcare information system (HIS) is ensured, and the exposure of sensitive data, which is difficult to achieve without the patients’ consent, is damaging to patient care. This study proposes AESRSA cryptography key for EHR data security, and the proposed cryptography technique is based on two efficient existing cryptography keys Advance Encryption Standard (AES) and Rivest-Shamir-Adleman (RSA) which are private and public cryptography keys respectively. The new system was implemented alongside the existing techniques (AES and RSA) using XAMPP, Apache Web server, MySQL database, PHP programming language, Hypertext markup language (HTML), and Javascript for EHR data. The three cryptography keys were evaluated using computing time, computing memory, processor consumption, and power consumption. The results show that hybridizing cryptography keys (public and private cryptography keys) is possible and improves the security of EHR data. Although the results of both encryption and decryption of the proposed cryptography key were slightly increased than the two existing cryptography keys but guaranteed improved security of EHR on the system prototype that was implemented, which was transmitted securely between the local server and the web server This was discovered to be a safe healthcare record system on the web that addressed user concerns about security and ensured the confidentiality, security, and privacy of patients’ health records.
