Cloud computing provides services in wide range for business firms. Nowadays small and medium businesses firms are depending for their data services and computation on out sourcing of on cloud. The cloud provides a very high efficient services for the business organizations. These business organizations trust cloud service providers for their data security. Providing security is highly risk in cloud, especially in private cloud services. Existing data security methods are not so effective. They are failed in preventing theft attacks. This paper propose a new approach for securing file hosting in private cloud service. OTFP – "One Time File Password" is an Email service that protects unauthorized access of file hosting account and file downloading form the cloud.
