Security of Electronic Health Record using Attribute based Encryption on Cloud

Because of the likelihood of data breaches and the potential hazards of patient information, healthcare institutions face significant challenges in implementing cloud-based Electronic Health Record (EHR) systems. Current authorization models are based on a patientdriven approach to EHR system management, in which the patient’s agreement to allowing data access is prioritised. However, the patient has a considerable burden in ensuring the security of their healthcare record. Given the problems that healthcare providers confront, many employees are apprehensive to use cloud-based EHR systems. Data breaches and patient data compromise can result in serious legal and financial ramifications for healthcare organisations. To overcome these issues, healthcare organisations must implement more robust permission models that prioritise patient data protection and privacy. This necessitates a transition from the present patient-driven strategy to a more proactive one that prioritises data security and privacy across the EHR management process. By introducing more advanced permission models and robust security mechanisms, medical organisations can minimise the dangers associated with cloud-based EHR systems while also ensuring patient data privacy and security. Not only will this improve patient outcomes, but it will also shield healthcare organisations from legal and financial responsibilities.
