As a part of Academics, we undertook this project. Fog Computing is web-based software for providing data security in the cloud when the attacker has already broken the primary security. It helps to save our valuable data from getting into the hands of attackers. We did this by giving time constraint, security question and changing the characters in the data. It is an application that enables organizations to save their valuable data and information even when the attacker has entered into the cloud by breaking in the primary security of the cloud.
