The healthcare sector has a very broad volume of patient information that needs to be recorded, and the cloud provides the necessary infrastructure at a low cost with better quality. The patient health records are implemented as digital output to Electronic Health Records (EHRs). The EHR can contain sensitive patient data such as data, scanned images, and X-rays. Security of the data in the cloud is an important issue due to different kinds of security threats to the cloud, such as distributed denial-of-service (DDoS) and man-in-the-middle (MITM) attacks. This study emphasizes the importance of data security in the hybrid cloud for the health sector using encryption with the Advanced Encryption Standard (AES). We present Data, Speed Efficiency, and Electronics Health Record (DSE), which defines each of the major components required to implement data security in hybrid cloud computing. EHR security is provided by using an encryption technique such as AES, which is implemented and uploaded to the hybrid cloud system. We approach the DSE taxonomy according to its speed and encryption. This study's main contribution is that it establishes a strong link between data security and healthcare organizations, as well as the open issues and challenges for patient data security in the health field. As a recommended solution, EHRs are encrypted with a secret key before uploading to the cloud server. Thus, the data will be safe as it cannot be changed without the help of the data owner and healthcare organizations.
