Cloud computing refers to the delivery of computing resources that is used in excess of the network. As an alternative of maintaining personal data on the own hard drive or updating important applications for user needs, user can use a service over the network, to a different location, to store user information and/or use its applications. This paper provides flexibility so it is very useful in a new generation of services and products. One of the main security problems in cloud is data mining based privacy attacks that involve analyzing data over a long period to extract valuable information.
