In this paper, we show how a dealer with limited resources is possible to share the secrets to players via an untrusted cloud server without compromising the privacy of the secrets. This scheme permits a batch of two secret messages to be shared to two players in such a way that the secrets are reconstructable if and only if two of them collaborate. An individual share reveals absolutely no information...
The wide spread use of Internet allows advertisers to reach significantly more consumers through online advertisement compared to traditional advertising media. However, currently online advertisement is facing challenges associated with advertisement (ad) frauds such as ad replacement, ad stacking, click fraud, and click hijacking. It is important to teach students this emerging topic, and help students...
The rapid growth in market demands for high-quality, state-of-the-art, and reliable communication services increases the amount of session-control signaling, which is mainly based on the Session Initiation Protocol (SIP). Many research activities dealing with the Quality of Service (QoS) have been focused on media-related service components, whereas signaling-related service components have received...
In the modern world, communication between people is being more important than ever, people are seeking for a more vivid, real-time way of communication. WebRTC (Web Real-Time Communication) is an upcoming technology that enables real-time communications capabilities in audio, video and data transmission via web browsers through Javascript APIs (Application Programming Interfaces). In this paper,...
The need for the reduction of energy consumption and size of microelectronic circuits is increasingly in demand. To support this request, this paper presents a comparison study on two integrated technologies: FDSOI 28nm and CMOS 350nm. The aim of this work was to compare the performance of these two technologies for the design of a rectifier and a Dickson charge pump for rectenna application. The...
Full mesh is the most commonly used networking topology in Web Real-Time Communication (WebRTC) based videoconferencing (VC) applications, however, due to its inherently poor scaling capability it is not appropriate for multi-party VC with many participants. Solutions based on centralized media server infrastructures are used to leverage the scaling problem. Service providers adopting centralized...
The actual task of research and development of methods and means for processing data in intellectual information systems forming content with the use of the classification, mathematical and software means and a generalized system architecture. The necessity for development of methods and means of processing data in intelligent information systems forming content by improving system architecture in...
With an average reading speed of 200–500 words per minute, at least human takes 2 to 3 minutes to read and understand one news in online media. The number of news updates on an online media in a few minutes can be a lot and it's time-consuming if a reader has to read the contents of all the news. Reading a summary that represents the main idea of the news can be a solution to save time. This study...
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,...
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...
Web cookies are ubiquitously used to track and profile the behavior of users. Although there is a solid empirical foundation for understanding the use of cookies in the global world wide web, thus far, limited attention has been devoted for country-specific and company-level analysis of cookies. To patch this limitation in the literature, this paper investigates persistent third-party cookies used...
This paper proposes a simultaneous transmission method of Multi-View Video and Audio (MVV-A) with MPEG-DASH. In the MPEG-DASH protocol, the server stores multi-bitrate encoded videos in advance and transmits an appropriate video depending on network condition. In the simultaneous transmission method, the minimum bitrate videos of unselected viewpoints are transmitted with the video of the selected...
Streaming Media is a multimedia that is presented to an end user which is constantly received by while being delivered by a provider. Amazon Web Service (AWS) is a collection of remote computing services (also called web services) that together make up a Cloud computing platform, offered over the Internet by Amazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3...
Video streaming now amounts to the majority of traffic in the Internet. Media streaming relies on large-scale content distribution networks (CDNs), that incur significant costs to build or use. P2P distribution of video content reduce reliance on CDNs and costs. Unfortunately, P2P distribution is fraught with QoE problems, specially during flash crowds or in scenarios where users have limited bandwidth...
Smartphones have become the de-facto capture devices for everyday photography. Unlike traditional digital cameras, smartphones are versatile devices with auxiliary sensors, processing power, and networking capabilities. In this work, we harness the communication capabilities of smartphones and present a synchronous/co-ordinated multi-camera capture system. Synchronous capture is important for many...
A cloud server spent a lot of time, energy and money to train a Viola-Jones type object detector [1] with high accuracy. Clients can upload their photos to the cloud server to find objects. However, the client does not want the leakage of the content of his/her photos. In the meanwhile, the cloud server is also reluctant to leak any parameters of the trained object detectors. 10 years ago, Avidan...
This paper is devoted to analysis of QoS parameters of WebRTC traffic presented for centralized videoconferencing system used for collaborative work. This system consists of a videoconference application, built according to the WebRTC architecture, and a telemetric system, built as the IoT environment. Tests were carried out for three locations of the conference bridge: in private cloud (the OpenStack...
Energy usage in data centres continues to be a major and growing concern as an increasing number of everyday services depend on these facilities. Research in this area has examined topics including power smoothing using batteries and deep learning to control cooling systems, in addition to optimisation techniques for the software running inside data centres. We present a novel real-time power-cycling...
The Dynamic Adaptive Streaming over HTTP (DASH) is specified to cope with the changing network conditions and provide an adaptive bit-rate HTTP-based streaming solution. While there have been many researches of rate adaptation algorithms on adaptive HTTP streaming, much of the work is focused on Video on Demand (VoD) service — which is not same as live streaming. It is generally preferred to minimize...
Wireless video surveillance is an important option suitable when it is difficult to have cable Internet and electricity infrastructure, which is the case, for example, for construction yards or vehicles. We present iCam, an open-source Internet-enabled video surveillance project, in which we use mainly discarded camera phones. The mobile application is written mainly in Python on most phone platforms,...
