Efficient and Secure Transmission of Digital Data in the 5G Era

With the arrival of new smartphones and new social networks and with the speed of the new 5G communication the network traffic of multimedia documents has significantly increased, and it becomes necessary to preserve privacy when using digital images or videos, for example in the current social networks or, even more, in those based on Virtual and Augmented reality that soon will take the place of the current ones. In this paper we explore a unified approach to compression and privacy by considering both one-dimensional and two-dimensional data by implementing a secure protocol for interactive data compression and by presenting a new algorithm for scrambling the Region of Interest (ROI) of an image.
