In cloud computing, cloud store the data with the different-different encryption technology, but if data or store increasers security of cloud also reduces, so we divide a cloud ne different sub cloud that is cloudlet. In this paper, we did a different encryption technology and signature key on cloudlets also and those signature key send to our register email id. In our paper every cloud is divide in cloudlet, for particular cloudlet want to access -user should register on them. In this user can access other cloud data and delete other data with the proper authentication in user side and main cloud server side. User can store any kind of data like pdf, image, text etc. Once user can store data on cloudlet other user can able use those data. © 2017, Institute of Advanced Scientific Research, Inc.
