  • Introduction: The use of advanced health care programs "remote information system" and "telematics" requires an integrated approach to apply the social, financial, cultural and political effects and remove the barriers of information technology and communication technology. Security and privacy are two important and critical features used to build a high security authentication protocol. Blockchain is a technology that has good features such as decentralization, independence, integrity, immutability, verification, error tolerance, anonymity, auditability, and transparency, which ensures high security for people. Putting blockchain into healthcare is proposed to eliminate the barriers and problems of data exchange inherent in electronic health record (EHR) systems that are disparate. Damage to privacy in medicine and health care causes a lot of economic and credit losses to hospitals and other health institutions, and may also cause various damages to patients and endanger their lives. Therefore, privacy is very important in medicine. The purpose of this review is to Design of Secure Authentication Protocol for Telecare Medical Information System Using Blockchain.
  • Methods: In the following article, we collected the required data by using key words using reliable databases such as Google Scholar, ProQuest, Scopus and PubMed. Our statistical population consists of all the studies that have been conducted until 2022. After reviewing the findings, we reviewed 14 articles.
  • Results: 1. In Telecare Medicine Information System (TMIS), the anonymity of patient is very critical and the violation of patients privacy can cause serious security issues 2. According to the results, electronic files and private health records are the most useful in using blockchain technology. Access control, interoperability, provenance and data integrity are all issues that are meant to be improved by blockchain technology in this field. 3.Providing secure authentication of people, the existence of a two-way, distributable and scalable process without a failure point, is possible by using the combination of public key construction and blockchain, which creates a secure environment for the electronic health network.
  • Conclusion: Thus, various cryptographic techniques based on distinct factors helped to protect the privacy of data and anonymity of patient .This system can improve the protection and privacy of patient records and prevent tampering . Blockchain is a potent and viable technology for patient access and exchange of health information. However, this technology remains at the prototype level and has limited functionality. Also, low throughput and high latency along with lack of technical stability of blockchain is one of the disadvantages of this technology. Blockchain is an ideal choice for improving existing computing systems in various ways. As one of the network-enabled technologies, cloud computing has been broadly adopted in the industry through numerous cloud service models. Fusing blockchain technology with existing cloud systems has a great potential in both functionality/performance enhancement and security/privacy improvement.
