Secured and Encrypted Healthcare Records with Granular Access Control in Distributed Systems

Abstract

Modern medical applications address complexities of earlier research, focusing on enhancing security and efficiency. The digitization of healthcare is being enhanced through information technology and computing, enabling the development of various new technolo- gies and medical devices. While existing systems have seen many more advances to save patients time and money, provide accurate care, and keep sensitive patient records secure, the biggest significant issue is confidentiality. To address the current security concerns in order to develop and construct the prototype model for security research work. For sensi- tive patient health records on database web servers. Existing efforts only data encryption can protect patient records from insider threats. The security of the physical layer of the SeSPHR Application is used in the proposed research work using keylogging techniques, the second to prevent insider attacks (external or internal attack like collusion attack, SQL injection at- tack, etc.) and store sensitive information or data of users or patients across multiple data servers using multi-instance database security (Chunks), and the third, and most importantly, implement a multiauthority search policy for encrypted data using the Access Control List (ACL) using Cipher’s Attribute-based Encryption (CP-ABE In the present research work is being added to securely clearly state the format of patient data records in multiple chunks (small pieces) and to use cryptosystems because of confidentiality of a patient’s medical information’s. Specifically, proposed research task benefits to use the SHA hashing tech- nique each user to allow access to specific data records. This research work investigates the proposed Role Base Access Control (RBAC) and the proposed Advanced Encryption Algorithm (AES)-512 bit encryption techniques for secure data storage and sharing for end- user strategies for securing access to the data. This work uniquely integrates multi-authority searchable encryption with AES-512 with AES-512 to ensure secure and efficient healthcare data management. This work also included the implementation of a backup server strategy, which functions as an all distributed data servers use an ad hoc network data recovery for proxy storage server.

Medical information is stored in hospital databases. Diagnosis and patient informa-

Tion have been secured in medical databases. Some data in medical databases is sensitive information and access to that data should be restricted to authorized individuals. Addition- ally, data integrity must be safeguarded to prevent unauthorised individuals from attempting
