Healthcare Services Monitoring in Cloud Using Secure and Robust Healthcare-Based BLOCKCHAIN(SRHB)Approach

摘要

Health Electronic Records (HER) share the data to improve the quality and decrease the cost of Healthcare. It is challenging because of techniques complexities and privacy compatibilities issues. The existing system is more popular to use the cloud-based healthcare system. However, the healthcare system is affected by content privacy and secure data transformation during data gathering and analyzing personal health records in cloud environments. The patient's records shared with patients, healthcare organizations, and insurance agents in a cloud environment. To offer a better solution for the above issues, a secure and Robust Healthcare-based Blockchain (SRHB) the approach proposes with Attribute-based Encryption to transmit the healthcare data securely. The proposed technique collects the data from the patient by using wearable devices in a centralized healthcare system. It observes patient health condition while in sleeping, heartbeat as well as walking distance. The patient obtained data is uploaded and stored in a cloud storage server. The doctor reviews the patient's clinical test, genetic information, and observation report to prescribe the medicine and precaution for a speedy recovery. Meantime, an insurance agent also evaluates the patient's clinical test, genetic information, and observation report to release the insurance amount for medical treatments. Blockchain concept implemented to maintain privacy in individual patient records. Each time it creates a separate block as a chain. Any changes in the block will be added as a new entry. Based on the experimental evaluation, SRHB reduces 2.85 AD (Average Delay) in seconds, 1.69 SET (System Execution Time) in seconds, and improves 28% SR (Success Rate) compared to conventional techniques.
