Attribute Based Encryption in Healthcare Application

Data volumes are increasing due to the growth of technologies such as IoT, Cloud Computing, and mobile internet. Data encryption is the solution, which protects data privacy by giving specific access to encrypted data can be better understood using Attribute-based (ABE) encryption. When patients use web-based commercial systems to store their personal health data, the privacy of personal health records (PHRs) can be a major problem. When it comes to establishing policies to control access and protect data confidentiality, common access control systems, such as Work-Based Access Control, have major limitations. In this research work a novel healthcare application has been developed based on the ABE scheme approach. Advanced Encryption Standard (AES) algorithm and Secure Hash Algorithm (SHA) are used for the encryption and decryption processes in the ABE scheme. This allows only designated authorized personnel, such as a patient or their respective doctors, to access personal data recorded in medical records, with a vision to improve the privacy and security of user details.
