Despite the Cloud Environment’s (CE) numerous and obvious improvements in healthcare, these issues continue to impede CE’s development. In order to fully understand and utilise such issues, the utmost serious thinking is required. Global, national, and local health information are in demand. Setting up the required security protocols for handling security issues and breaches is essential for getting the most out of healthcare services. The Modular Encryption Standard (MES) is therefore being investigated for this research in order to provide requirement-based health data protection in light of the tiering of security efforts. According to the presentation evaluation, the suggested work outperforms other regularly used calculations against the security of health data in the CE environment in terms of enhanced performance and practical subjective security ensuring approaches.
