Multi-Privacy Level Encryption Technique For Secure Cloud-Based Data Repositories

Cloud security encompasses the deployment of advanced technologies, methodologies, and programming to safeguard cloud-based applications, ensuring their protection against potential threats and vulnerabilities. Cloud computing is an environment for providing services namely platform, software, hardware and infrastructure on user demand posing a serious challenge for enabling high secure digital data cloud repository. To keep sensitive information safe in cloud computing, we must use strong techniques to protect it from external attackers. In today’s world, creating a security system that will last a lifetime is extremely difficult, as attackers gain more ways to access data as time progresses. Hence, we create a web based application that uses several encryption levels, including the DNA algorithm, Vigenere Cipher, and Advanced Encryption Standard (AES) algorithm to achieve greater confidentiality before loading a digital data onto cloud storage.
