Secure Proxy Service Using p-Fibonacci Transformation of Cosine Coefficients on Cloud File Sharing Environment

In this paper, we sketch the idea of double image encryption service to provide the privacy and authentication on big-data image libraries on cloud computing environment. The encoding of the image is done using the P-Fibonacci transform of Discrete Cosine Coefficients "PFCC" algorithm. First, using Discrete Cosine Transfer (DCT), we transfer an image from the spatial domain to the frequency domain. Second, we utilize the Fibonacci P-code for image bit-plane decomposition and the 2D P-Fibonacci transform for image encryption. Furthermore detailed simulations have been carried out to test the encryption service on cloud file sharing environment such as OpenStack Object Storage and flicker.
