Data Recovery and Security in Cloud

Cloud computing has been evolving with an increasing popularity, which leads to the rapid adaption of cloud services for various reasons among the individuals and organizations. The main reason for this shift is because of the numerous benefits provided by cloud services such as low costs, computational power, and storage services over the Internet. Data recovery is one of the important concepts while dealing with storage devices which are basically the backbone of the cloud infrastructure. Someone with access to these servers or devices can use data recovery techniques to reconstruct the confidential data of customers once the customers have deleted their confidential or private data from the cloud. Reconstruction of such data leads to a security problem and privacy concerns for users. Even after some gains access to their data users are not aware that someone else has access to their data even though it has already deleted in their point of view from the cloud. In this paper, we look into the security problem which can arise based on the usage of data recovery tools on cloud infrastructure, once the users have deleted their data. To address this problem, we have proposed a simple method using Rename.
