DATA SECURITY and PRIVACY PROTECTION for CLOUD STORAGE

Abstract: At the forefront of this trend are the Internet of Things, smart cities, digital transformation of businesses, and the global digital economy. Due to the enormous amount of data collected, the strain on data storage is only going to increase, propelling the quick growth of the entire storage business. The ability to store and manage data makes cloud storage systems an essential component of the modern world. Governments, businesses, and individual users are currently actively moving their data to the cloud. An enormous volume of data can yield enormous riches. On the other hand, this raises the possibility of risks such data leakage, illegal access, revelation of sensitive information, and privacy disclosure. There are research on data security and privacy protection security, but systematic surveys on the topic in cloud storage systems are still lacking. In this study, we conduct a thorough literature review on data encryption technologies, privacy and security concerns, and relevant countermeasures for cloud storage systems. In particular, we begin by providing an overview of cloud storage, including its definition, categories, architecture, and uses. Second, we provide a thorough examination of the difficulties and specifications related to Cloud storage's data security and privacy protection systems. Thirdly, a summary of data encryption technologies and security techniques is provided. In conclusion, we address various unresolved research issues related to cloud data security storage.
