Content Auditing in the Cloud Environment

Abstract

Cloud computing is a new computing paradigm that enables organizations and users to store data in a highly available space of different shared applications and services, instead of storing and managing their data on the company's local server. There are some challenges that face cloud users when they use cloud storage services like inability of accessing their data physically, so if the user doesn't know the Cloud Service Provider (CSP), malicious activity on untrusted servers can alter or destroy their data and applications. As a conclusion content auditing, must be a requirement, a scheduled check for data is done as a correction purpose and this method is called data integrity. This paper proposed a model that provides content auditing of cloud user data which can be personal data or web pages by periodically checks data integrity by using keyed hashing algorithms and check trustiness of Cloud Service Provider, finally ensure the fast recovery of data.
