In this paper, The evolution of cloud computing is used to increase in image size and making the outsourcing of image storage. Data confidentiality is the main source of cloud computing. The main concern in data confidentiality is used to state-of the-art encryption scheme. The state-of the-art schemes do not allow cloud datacenters to operate encrypted images. Paillier changes the multi Crypt to Cryptosystem-based image scaling and cropping schemes. Paillier cryptosystem-based scheme is used for multi-user settings and it allows cloud datacenters and is used to image scaling and cropping in the encrypted domain. According to multi Crypt, multiple users can process the images without sharing anyone to use. Multi Crypt analysis shows an IND-CPA secure and results an acceptable overhead .When scaling a 512*512 image in multi crypt, user to download image approximately 5:3 times more than the un-encrypted scaling data. It works approximately 2:3 seconds more for obtaining the scaled image in plaintext.
