Smithamol et al. Despite its significant impact in healthcare domain, adopting this paradigm to save medical data on remote servers poses serious challenges, especially security risks. The survey reveals that cloud adoption continues to grow and 81% of respondents have a multi-cloud strategy. The authors declare that they have no conflicts of interest. The new regulation gives consumers the right to be forgotten, data must be permanently erased if requested. GDPR is the European Union (EU) primary tool that regulates the protection of EU citizens individual data. The main features of cloud computing is that the user does not have any setup of expensive computing infrastructure and the cost of its services is less. On contrary, the article does not discuss any aspects of the optimal number of shares for the incurred trade-off between efficiency and security. Migration of an organization data to the cloud is a, strategic and complex decision. In this paper, we study the use of cloud computing in the healthcare industry and different cloud security and privacy challenges. As far as we know, there are only a few works in literature that deal with availability and data recovery in cloud computing. Ownership and Privacy of Healthcare Information. Overall, accredited registrars are reporting an increased demand on ISO/IEC 27001 certification from service providers [92]. is is an open access article distributed under the Creative Commons Attribution License, cloud computing is a model for enabling ubiquitous, con-, Private cloud: it is located on premises, over the, Community cloud: it is a group of entities with a, Improved patient care because of the continuous. What are the security challenges hindering the wide-scale adoption of cloud computing by healthcare providers? HITECH Act regulations were motivated by the lack of, financial resources, shortage in technical expertise, and the, lack of a secure infrastructure for exchanging healthcare, information [87]. Privacy could be claimed as, a moral right for individuals and groups when using in-, formation systems, whereas computer security is not a moral, right in itself. [74] B. Dhivya, S. P. S. Ibrahim, and R. Kirubakaran, cryptographic access control for cloud based electronic, Research in Computer Science, Engineering and Information, [76] S. Supriya and S. Padaki, “Data security and, lenges in adopting solutions for IOT,” in, 2016 IEEE International Conference on Internet of ings, (iings) and IEEE green Computing and communications, (GreenCom) and IEEE cyber, Physical and Social Computing, IEEE 3rd International Conference on Cloud Computing, ohr, A.-R. Sadeghi, and M. Winandy, “Securing the. It became an important process, because unauthorized eyes could have access to the data on, the way, causing data integrity issue (data could be modified, (TLS) has been utilized to secure communication between, web applications. However, the security challenges imposed by these technologies are inventible and alarming compared to traditional eHealth cloud technologies. from consumers, customers also have the right to opt out, and businesses should keep a log of all consumer consents, [100]. Most of those solutions address part of the problem, and they failed to balance all contradicting security requirements. communication is an example of a secure implementation. As a result, security, privacy, efficiency, and scalability concerns are hindering the wide adoption of the cloud technology. Providers can dynamically allocate resources according to the fluctuations in demand, and the client is completely unaware of the physical locations of these services. Security and privacy issues are among the most talked about topics in information technology and communications fields. Privacy by design means that service providers should. e Act considers the confi-, dentiality of health data to be an obligation, not an option, cloud computing applications have multiple security re-, quirements to be fulfilled. Amazon EC2 is a good example [12]. The proposed approach minimizes the computational overhead and the overall encryption time. Before moving data into the, cloud, the security challenges should be mitigated. In the proposed framework, public key in-, frastructure (PKI) is used to maintain authentication be-, tween participating healthcare providers and the EHR, sharing cloud. ird, encoding and encrypting data; however, there is a chance to, reveal the encryption key using advanced computer tech-, nology. identi ed cloud computing security challenges (43) and solutions (89), can be referred by practitioners to understand which areas of security need to be concentrated while adapting/migrating to a cloud comput- Nov 1 pp. Some personal data like personal healthcare records and financial records contain sensitive information which can be analyzed and mined for public researches although these records offer important human assets. Just like every other ITapplication, the cloud has various ... security risks for eHealth systems using cloud computing. Versicherungsmedizin / herausgegeben von Verband der Lebensversicherungs-Unternehmen e.V. Computer security is a growing field in computer science that focuses on protecting computer systems and electronic data against unauthorized access, hardware theft, data manipulation, and against common threats and exposures such as backdoors, denial-of-service (DoS) attacks, and phishing.
