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.

使用安全可靠的基于医疗保健的BLOCKCHAIN（SRHB）方法在云中进行医疗保健服务监控

健康电子记录（HER）共享数据以提高质量并降低医疗保健成本。由于技术复杂性和隐私兼容性问题，这具有挑战性。现有系统更流行使用基于云的医疗保健系统。但是，医疗保健系统在数据收集和分析云环境中的个人健康记录期间会受到内容隐私和安全数据转换的影响。在云环境中，患者的记录与患者，医疗机构和保险代理商共享。为了为上述问题提供更好的解决方案，该方法提出了一种基于健壮的安全健壮的基于医疗保健的区块链（SRHB），以基于属性的加密来安全地传输医疗保健数据。所提出的技术通过使用集中式医疗保健系统中的可穿戴设备从患者收集数据。它可以观察患者在睡眠中的健康状况，心跳以及步行距离。患者获得的数据被上载并存储在云存储服务器中。医生会检查患者的临床测试，遗传信息和观察报告，以开具药物和预防措施以加快康复。同时，保险代理商还评估患者的临床测试，遗传信息和观察报告，以释放用于医疗的保险金额。实施区块链概念以维护个人病历中的隐私。每次它创建一个单独的块作为链。块中的任何更改都将添加为新条目。根据实验评估，
