Security and Privacy Designs Based Data Encryption in Cloud Storage and Challenges: A Review

Cloud computing technology use in many companies as well as individuals and Cloud Service Provider (CSP) stores their user data in the third party storage. This creates a high threat to user data security and there is a huge demand for securing the user data. In order to protect user data from the intruder, many data encryption techniques have been proposed. In this paper, an analysis has been provided in the research of data security in the cloud storage with various output parameters. Bloom filter technique [39] is a technique utilized in the data encryption and key generation discussed in this paper. In the research of Wei Wu, et al. [34], the encryption has been carried out with the computational time of 0.037s when the dimension of database is present as 500 by using K-nearest neighbor classification.
