An Innovative Method for Authenticating and Accounting for Cloud-based Financial Transactions is to Publicly Disseminate the User's Private Key

Cloud computing (the practice of storing data on remote servers) is a fast and economical way for businesses to develop with little to no additional capital investment. One of the most appealing aspects of cloud data storage solutions is the scalability to accommodate ever-increasing data loads. When data is stored and accessible over the internet, as it is in a cloud environment, its integrity might be compromised and customers can become dissatisfied. Users can buy computing resources, data storage, and a plethora of other software services online and tailor them to their specific needs. In cloud computing, users can tap into an abundance of shared computing resources. Modern cloud computing systems rely on asymmetric and traditional public key cryptography for data security and mutual authentication. Data security and protection are improved by this research without any loss of data quality. The data are separated into three categories, with the owner assigning importance to each. Before being stored in the cloud, data from each layer might be encrypted using a separate key. The data will be protected from intruders and other threats using this way. It will also be easier and cheaper to keep encrypted data in the cloud. This study employs the Advanced Encryption Standard (AES) throughout the model's creation in order to gauge its reliability.
