Abstract

Times have revolutionized the cloud domain with its data storing capabilities and hosting services. This incentivizes the concept of remote storage for total user accessibility. However, this data is not secured and is put to risk for data misuse. This often leads to exposure of user data and breaches the integrity of the system. Moreover, since cloud is an open-source platform; simultaneous services to users often leads to data leaks. To avoid such scenarios; it has become crucial to secure data repositories from third party usage to be protected on the cloud. Therefore, the proposed research thesis aims to maintain the security and confidentiality of the system while deploying a healthcare app on various cloud platforms and leverage Cloud Service Providers(CSPs). A hybrid encryption mechanism is created from a novel approach using Advanced Encryption Standards(AES) and Advanced Encryption with Associated Data (AEAD). Additionally, Amazon Web Services(AWS) along with Continuous Integration and Continuous Delivery(CI/CD) Pipeline is also integrated into the project to ensure security and data integrity such as CodeRun, CodeDeploy and CodeBuild. The time metrics of the text conversion is evaluated, furthermore through case studies and Avalanche score is generated to indicate the strength of the algorithm with results reaching up to 93.8%. MySQL is used in the back end to manage the database and monitor user uploads. The healthcare app is finally deployed on cloud using the multi cloud technique using Microsoft Azure and Elastic Beanstalk.
