When file owner like to store the file into cloud server that time file owner file upload request send to the provider. That time provider sends the file upload key to the file owner. When provider receives the file from the file owner that time provider upload the file into the cloud server. Here provider split the file index and file store the different location in cloud server. This is mainly used for the security of the files. Same time when file owner want to view the upload file from the cloud server that time file owner send the request to provider. That time provider in case of not view to file owner request that is the main problem of the existing system. So here we are learn about how to overcome this problem. That the above functions are same but one different for when upload the file from the provider that time index keys are stored to the trapdoor. Trapdoor means like a virtual machines this trap door mainly used for the when file owner request send to the file key that time automatically fetch the key from this trapdoor this is mainly used for work load reduce for the provider and time reduce for the file owner access the file key. Here that file keys are encrypted format when store into cloud server because unauthorized can’t access the file without permission of provider. The main scope of this paper is to solve the security problems and retrieve the document form the cloud sever. This is used to reduce the time to access document from cloud.
