:- The importance of data security has been a significant problem in information technology. Because the data is spread out all over the place in the field of technology, it becomes extremely problematic. Users' primary worries regarding cloud computing are related to data security and privacy security. Despite the fact that numerous approaches to the issue of cloud computing have been studied in academic research and clinical trials, data security and privacy protection are becoming increasingly crucial for the future use of cloud computing technology in business, industry, and government. In the cloud architecture, concerns about data security and privacy security apply to both hardware and software. This research aims to improve data security and privacy security for a reliable cloud environment by examining various security strategies and exceptions from both software and hardware aspects for securing data in the cloud. a comparison of the study that has already been done on the data security and privacy security methods utilised in cloud computing.
