It has been shown that there exist significant computational resources in user equipment deployed in enterprises, which are under-utilized most of the time. A new architecture was proposed in order to use these resources as media servers, in order to handle tasks such as video mixing, trans-coding, etc. This represents an economical and efficient alternative to MCU-based or P2P architectures. However,...
Finance institutions have always needed enhanced security to protect their assets. Today that want to enjoy access to the cloud as well as new communication technologies like WebRTC. In parallel, the IETF created a new working group called Privacy Enhanced RTP Conferencing (PERC) that propose solutions to allow usage of media servers in the public cloud without compromising the security. This work...
It is of utmost importance for the future success of WebRTC to ensure that interoperability is operational between web browsers and any WebRTC-compliant client. To be guaranteed as operational and effective, interoperability must be tested extensively by establishing WebRTC data and media connections between different web browsers running on different devices and operating systems. We will present...
This paper describes a system that provides the indoor location of an emergency 9-1-1 caller who uses a smart-phone while inside a large, multi-story building. The system consists of an Array of BlueTooth Low Energy (BLE) beacons and a Database that together provide the indoor location, and a Smartphone Application that obtains the location information and makes an IP-based call, including the indoor...
This paper presents the design and implementation of the Docker Security Playground (DSP), an architecture leveraging a microservices-based approach in order to build complex network infrastructures specifically tailored to the study of network security. DSP has been conceived at the outset as a tool for learning network security with a hands-on approach. A number of security labs have been already...
Recently, blockchains have been gathering a lot of interest. Many applications can benefit from the advantages of blockchains. Nevertheless, applications with more restricted privacy or participation requirements cannot rely on public blockchains. First, the whole blockchain can be downloaded at any time, thus making the data available to the public. Second, anyone can deploy a node, join the blockchain...
This paper discusses how to add privacy features to the Janus WebRTC media server and gateway. In order to do so, we embrace a standard approach, by leveraging work currently ongoing within the IETF PERC working group. PERC stands for Privacy Enhanced RTP Conferencing and is aimed at enabling centralized real-time conferencing in a scenario where the central media forwarding entity is not required...
