In recent years, the block chain technology considered as adaptable compared to other techniques. Many of the industry, understanding the block chain technology is utilizing for financial services and its transactions but it also effective in other sectors like healthcare industry. Existing methods are hazardous; where, data stored in outsider servers might be eavesdropped, stolen, or legitimate
... [Show full abstract] way. Nevertheless, the trustworthiness of storage server architecture relies upon dependability of single service provider. The security manager’s detect the which are client(s) can get to a specific part of the data. However, the existing method is increasingly failed to maintain access control, record transaction authentications with anonymous interruptions. The paper proposes a secure and efficient health record transaction utilizing block chain (SEHRTB) algorithm for addressing health record information transaction between the patient, doctor, service providers, and institutions in a privacy-preserving way. The work provides a healthcare sector with block chain technology. In health care, the work enables the patient to control and share their health record into cloud storage easily in a secured manner without any violation of privacy. It provides an effective way to ensure the patient data privately in intelligent health care systems. The paper indicates the system built in a decentralized computing system to assure trusted third party for conducting computation over patient data without violating the privacy. Based on Experimental result, the SEHRTB algorithm reduces 2.05 latency, 1.08 ET (execution time), and improves 30.5% throughput compared than existing approaches.
