- 3. Introduction Digital Health The most far-reaching trend in the Healthcare Industry is Digital Health these days. It’s a broad array of the technologies like mHealth (Mobile Health), HealthIT (Health Information Technology), wearable devices and mobile health applications, and telehealth and telemedicine services. Digital Health in Cloud Computing Transforming or using the technology to enter your health concerns and symptoms into a web or mobile application with the insurance details and accessing that information from anywhere around the globe securely and safely is digital health in cloud computing.
- 4. Cont. Introduction The future healthcare industry will be information- centric that allows us to manage complexities. With clouds, electronic health records (EHRs) are maintained. These records need to be protected. Unauthorized access, data theft, data manipulation, phishing, and denial-of-service (DoS) attacks are the emerging threats of digital health with respect to cloud computing (Maria, 2019). The confidential data can be protected by securing the system with authentication and authorization tools, transmitting the data in encryption form, and using the trusted cloud service providers.
- 5. Background and Literature Review The healthcare industry is converging with digital technologies to increase the efficiency in their practices and make medicine personalized to deliver quality healthcare. The reason behind the growing demand for diverse medical care and additional resources is the dramatic increase in average life expectancy. The healthcare moved to cloud computing as they started generating a significantly high amount of data on a regular basis. The data generated by healthcare is important and needs to be preserved for decision making and to provide good quality services to the patients. The implementation of cloud computing is cost-effective, minimizes the operation cost, and facilitates real-time data collection, data storage, and transmission of data forcing the healthcare to shift the operations over the cloud and implementing cloud computing services in their organizations. The high volume of data is exchanged by the healthcare organization in a secure and efficient manner with clouds (Aziz, 2016).
- 6. Background and Literature Review Cloud computing in healthcare is a new concept and the use of innovation and technology in this field could give rise to emerging threats and challenges. Traditionally the data was stored on a physical system giving access only to the organization in a location. To enhance the services there was a need to shift the data to a more flexible system. Healthcare organizations decided to opt for digital health and cloud computing and its implementation provides flexibility in managing, accessing, and transferring data on clouds. The information of healthcare contains critical data of patients including name, address, and medical history which need to be secured. Cloud computing manages the privacy and security of the data with authentication and authorization tools.
- 7. Presentation of the Main Contribution of the Paper The research is focused on the cloud computing and the emerging threats due to the implementation of cloud in healthcare organizations. The organizations has implemented clouds for the data processing. The infrastructure as a service (IaaS), Platform as a service (PaaS), and software as a service (SaaS) are the three service models provided by cloud computing. The use of cloud computing not only speeds up operations with easy management but also requires less maintenance and is cost-efficient. It brings attractive benefits like remote storage, flexible on-demand access, universal data access, storage management, and avoiding extra capital expenses. It does not need any special hardware or software for its implementation and maintenance (Arunkumar, 2017).

- 9. Presentation of the Main Contribution of the Paper The cloud architecture ensures a safe environment for creating, storing, processing, communicating, and managing the patient’s data. It is the responsibility of healthcare to educate consumers about their role in security. The security and privacy in healthcare are maintained by high-security measures, government regulations, and rules, and comply with legislation to ensure the patient’s data protection. The digital health service providers come with built-in security measures in EHR. The digital health includes tools to manage and monitor access in the system by creating logs.
- 10. The below are few examples of the laws and enactments implemented in the different countries:
- 11. Research Methodology Hypothesis: 1. Digital health care provides better facilities and also avoid complexities. 2. Cloud computing used to manage data like Electronic health records are the most beneficial. Methods of data collection: 1. Primary sources: Questionnaires, Interview 2. Secondary Sources: Internet Books/Brochure Peer reviewed Articles Websites Applications
- 12. Research Methodology This research is aimed at studying the digital health which is the convergence of digital technology in healthcare and also their advancements that are implemented in digital health to provide better facilities. Expected Outcome from this research could be very beneficial as the future healthcare industry will become diligent that will surely overcome all the complexities. The Records will be saved on clouds and a better Electronic Health record would serve a patient in an emergency. This research will lead to a positive outcome.
- 13. Results and Findings It was found that the implementation of the cloud computing in the healthcare reduced the time and operation cost of the organization. Flexibility in providing services was achieved as it allowed universal access. It provides access to the patients securely via unique identification number. The EHR combined with cloud computing manage the complete information of the patient’s resolving “Big data” problems. The patient’s complete medical records are obtained and stored in a uniform manner that reduces the wait time by making the reports available remotely
- 14. Results and Findings The doctors, physicians, researchers, and statisticians, all can access the patients report simultaneously even if they are miles apart to provide a better, secure, and faster service. The data is stored on the networks in encrypted form. The EHR uses different algorithm like AES, and homomorphic encryption algorithm to encrypt the data stored in EHR. Based on several permutation and linear transformations, the data is executed on blocks transferring the plain text into encrypted text. The AES is the standard for the government standards and high security system (Arunkumar, 2017). These algorithms can also be used to encrypt the medical images.

- 16. Limitations Network connection dependency Security and privacy of the cloud computing Vulnerability Limited control and flexibility to cloud Customer lock-in Handle big data flood with intensive security and with highly skilled hands in digital health. s The awareness regarding digital healthcare is low when compared to other technologies. Technological problems can cease the on-going process which may result in huge problems in times of emergency cases. Minor concerns like power cuts, power outages, loss of internet connectivity resulting in disconnection with the cloud can also occur in such cases.
- 17. Conclusion With cloud computing and digital health, numerous opportunities are offered to drive health research, digitalization of healthcare industry and so on. Privacy and security of the sensitive data of the patient is an utmost priority and a highly secure connection costs a lot of expense to any healthcare organization. various methods are used to prevent patient's privacy in healthcare including Attribute- based encryption Access Control (AES), and Homomorphic encryption. It provides effective solutions to the problem in digital health care and data security.
- 18. Conclusion The digitalization of the healthcare industry promises to deliver many benefits, on the contrary, it also raises some barriers and challenges. It enables the organization to control the resources and provide the services accordingly as full administration, or role-based access control. Different cloud models like private, public, or hybrid clouds can be implemented based on the requirement. The digital health resolves the storage issue, security, privacy, flexibility, reliability, and availability of data between the patients and the healthcare organization.
