Abstract
Cloud computing delivers convenient, on-demand access to shared pools of data, applications and hardware over the internet. Cloud computing provides unlimited infrastructure to store and execute customer data and program. Due to this redundancy the data can be easily modified by unauthorized users which can be stored in the database. This leads to loss of data privacy and security to database. Extensive security and performance analysis shows that the proposed scheme ensures that cyclic redundancy check and time-tested practices and technologies for managing trust relationships in traditional enterprise IT environments can be extended to work effectively in both private and public clouds. Those practices include data encryption, strong authentication and fraud detection, etc. Property theft is prevented due to strong authentication mechanism, which includes stronger fraud detection methods.
