Data usage control is of utmost importance for federated data analytics across multiple business domains. However, the existing data usage control approaches are limited due to their complexity and inefficiency. This paper proposes an intentoriented data usage control system for federated data analytics, called IntentKeeper. The system allows users to specify intents for data usage policies and services easily. Thus, it reduces the data sharing complexity for data providers and consumers. Moreover, IntentKeeper enforces preventive and proactive data usage control for better security and efficiency through joint decisions based on policy enforcement and service orchestration. The use case validations for the automotive industry scenario show that IntentKeeper significantly reduces the complexity of policy specification (up to 75% for moderately complex scenarios) compared to the state-of-the-art flow-based approach. Lastly, the experimental results show that the IntentKeeper system provides sufficiently short response times (less than 40ms) with minimal overhead (less than 10ms).

Machine learning (ML) applications in Internet of Things (IoT) scenarios face the issue that supervision signals,such as labeled data, are scarce and expensive to obtain. For example, it often requires a human to manually labelevents in a data stream by observing the same events in the real world. In addition, the performance of trainedmodels usually depends on a specific context: (1) location, (2) time and (3) data quality. This context is not staticin reality, making it hard to achieve robust and transferable machine learning for IoT systems in practice. In thispaper, we address these challenges with an envisioned method that we name Knowledge Infusion. First, we presenttwo past case studies in which we combined external knowledge with traditional data-driven machine learning inIoT scenarios to ease the supervision effort: (1) a weak-supervision approach for the IoT domain to auto-generatelabels based on external knowledge (e.g., domain knowledge) encoded in simple labeling functions. Our evaluationfor transport mode classification achieves a micro-F1 score of80.2%, with only seven labeling functions, on parwith a fully supervised model that relies on hand-labeled data. (2) We introduce guiding functions to ReinforcementLearning (RL) to guide the agents’ decisions and experience. In initial experiments, ourguided reinforcementlearningachieves more than three times higher reward in the beginning of its training than an agent with no externalknowledge. We use the lessons learned from these experiences to develop our vision ofknowledge infusion. Inknowledge infusion, we aim to automate the inclusion of knowledge from existing knowledge bases and domainexperts to combine it with traditional data-driven machine learning techniques during setup/training phase, butalso during the execution phase.

This paper proposes Group-In, a wireless scanning system to detect static or mobile people groups in indoor or outdoor environments. Group-In collects only wireless traces from the Bluetooth-enabled mobile devices for group inference. The key problem addressed in this work is to detect not only static groups but also moving groups with a multi-phased approach based only noisy wireless Received Signal Strength Indicator (RSSIs) observed by multiple wireless scanners without localization support. We propose new centralized and decentralized schemes to process the sparse and noisy wireless data, and leverage graph-based clustering techniques for group detection from short-term and long-term aspects. Group-In provides two outcomes: 1) group detection in short time intervals such as two minutes and 2) long-term linkages such as a month. To verify the performance, we conduct two experimental studies. On consists of 27 controlled scenarios in the lab environments. The other is a real-world scenario where we place Bluetooth scanners in an office environment, and employees carry beacons for more than one month. Both the controlled and real-world experiments result in high accuracy group detection in short time intervals and sampling liberties in terms of the Jaccard index and pairwise similarity coefficient.

Infrastructures enabling experimental assessment of Internet of Things (IoT) solutions arescarce. Moreover, such infrastructures are typically bound to a specific application domain, thus, notfacilitating the testing of solutions with a horizontal approach. This paper presents a platform that supportsExperimentation as s Service (EaaS) over a federation of IoT testbeds. This platform brings two majoradvances. First, it leverages semantic web technologies to enable interoperability so that testbed agnosticaccess to the underlying facilities is allowed. Second, a set of tools ease both the experimentation workflowand the federation of other IoT deployments, independently of their domain of interest. Apart from theplatform specification, this paper presents how this design has been actually instantiated into a cloud-basedEaaS platform that has been used for supporting a wide variety of novel experiments targeting differentresearch and innovation challenges. In this respect, this paper summarizes some of the experiences fromthese experiments and the key performance metrics that this instance of the platform has exhibited duringthe experimentation.
