A majority of traffic in Internet today is media sharing, which is increasing at a rapid pace. Consequently, media industries face challenges due to the associated steep rise in bandwidth, computing, and storage requirements. To face the challenges, in this paper, we sketch a new methodology, named ‘Secure Processing-aware Media Storage’ (SPMS) through expanding cloud file sharing capabilities from only storing media files to also processing them along with encryption. Our proposed approach is to package application requirements and move data after processing them based on the package of requirements. Here, first, we propose to perform resizing of images and transcoding of videos according to several resolutions for covering diversified remote devices. Afterwards, we perform necessary media encryption-decryption. These tasks are performed using several middlewares. To validate efficacy of our proposed methodology, we perform a set of experiments with implementation of the middlewares over a real private cloud enabling file sharing. Experimental results confirm substantial performance improvement using our proposed methodology compared to that obtained using conventional one.
