Building Management Systems (BMSs) have evolved in recent years, in ways that require changes to existing network architectures that follow the store-then-analyse approach. The primary cause is the increasing deployment of a diverse range of cost-effective sensors and actuators in smart buildings that generate real-time streaming data. Any in-building system with a large number of sensors needs a framework for real-time data collection and concurrent stream processing from sensors connected using a range of networks.
We present SenseRT, a system for managing and analysing in-building real-time streams of sensor data. SenseRT collects streams of real-time data from sensors connected using a range of network protocols. It supports concurrent modules simultaneously performing stream processing over real-time data, asynchronously and non-blocking, with results made available with minimal latency. We describe a prototype implementation deployed in two University department buildings, demonstrating its effectiveness.
The TV is Smart and Full of Trackers: Towards Understanding the Smart TV Advertising and Tracking Ecosystem
由于智能电视的日益普及,我们提出了一个大规模的测量研究的智能电视收集和分析他们的网络流量从两个不同的有利位置。首先,我们分析了从数十个家庭的住宅网关和几个不同的智能电视平台(包括Apple,Samsung,Roku和Chromecast)收集的智能电视的总网络流量。除了访问视频流和云服务外,我们还发现智能电视经常连接到知名的以及特定于平台的广告和跟踪服务(ATS)。其次,我们通过建立一个受控的测试平台来测试Roku和Amazon Fire TV这两个流行的智能电视平台,系统地测试每个平台上的前1000个应用程序,并以单个应用程序的粒度分析它们的网络流量。我们再次发现,智能电视应用程序连接到广泛的ATS,这两个平台的ATS生态系统的关键参与者彼此不同,也不同于移动平台。第三,我们评估了最先进的基于DNS的阻止列表在过滤广告和跟踪智能电视流量方面的有效性。我们发现,个人身份信息(PII)被泄露到与平台相关的互联网端点和第三方,并且阻止列表通常更好地防止PII暴露给第三方,而不是平台相关的端点。我们的工作展示了智能电视ATS生态系统跨平台的细分及其与移动ATS生态系统的差异,从而激发了专门为每个智能电视平台设计隐私增强工具的需求。
