Abstract: A distributed collection of related and connected systems with additional resources made available on a pay-per-use basis is known as cloud computing. It has more to do with other computing technologies, such as autonomous computing, grid, and utility computing, among others. Because of its virtualization technology, the Cloud differs from other platforms, particularly the Grid. Cloud service providers (CSPs) like Google, Amazon, Salesforce.som, Microsoft, and others store and manage client data in their data centres. Cloud computing is entirely internet-dependent technology. CSP is in charge of keeping an eye on and maintaining the data that is outsourced. Data leaks, insecure interfaces, resource sharing, data availability, and insider attacks are just a few of the security risks and problems that can arise from having little control over the data. Security, availability, performance, lack of standards, higher usage costs, and difficulty integrating with on-premise IT resources are the first problems. Because they don't know where their data will be stored, when it will be available to them, or how it will be processed by others, many customers don't fully rely on the cloud environment. For these reasons, a large number of researchers focus on the cloud's "security." This study proposes a technique of confidentiality called Magic Square Obfuscation (MSO) to enhance data security and add complexity to the obfuscated text.

Keywords: cloud, data security, CSP, confidentiality, obfuscation.
