Proposed iPrivacy based Image Encryption in Mobile cloud

Abstract

Basically, people can be capturing images and outsourced to the mobile cloud. Privacy of image is the major challenge to be facing now-a-days. Encryption is one of the greatest solutions to security. While outsourced the image data to the cloud, Cloud Service Provider (CSP) could be possible to share the image to the unauthorized users for their profit. And the past encryption techniques such as AES, DES, RSA are unsuitable to image than text. Due to the lacking of CSP and past encryption techniques, we propose the encryption technique called iPrivacy-Pseudo Random Permutation (PRP) based Encryption, which is applied to the image to ensure security/privacy. The proposed scheme(iPrivacy-SDS) handled by three simple steps such as Split, Distribute and Scramble to attain secure and fast execution. The proposed work may prevent users from accessing of private images. The experimental results show that the time consumption is efficient and around 50% reduction while compared to AES and compared with various image formats such as JPEG, BMP, GIFF and PNG.
