In this paper we study the problem of estimating the cardinality of pairwise set operations (union and intersection) over sets possessed by different data owners, while preserving differential privacy. In our problem setting, a data owner could only communicate with an untrusted server, and thus have to perturb its set data for privacy protection before sharing them with the server. This problem setting...
Proposals and some implementations of Internet of Things (IoT) systems for healthcare are described. Implications of current European Union legislation, the new General Data Protection Regulation, for the security and reliability of healthcare IoT systems and for the privacy of users of these systems are presented. Analytics of healthcare IoT data for the requirements of evidence based healthcare...
Smartphone, as a personal device, has been widely used in people's daily life. As a result, it unavoidably contains user's private and sensitive information, such as financial accounts and social contacts. Unfortunately, recent studies have shown that fingerprint of sensors in smartphones can be used for tracking them, which leads to a significant threat to user's privacy. More importantly, speakers...
In this paper we address the issue of connecting abstract task definitions at a mission level with control functionalities for the purpose of performing autonomous robotic missions using multiple heterogenous platforms. The heterogeneity is handled by the use of a common vocabulary which consists of parametrized tasks such as fly-to, take-off, scan-area, or land. Each of the platforms participating...
6LoWPAN networks involving wireless sensors consist of resource starving miniature sensor nodes. Since secured authentication of these resource-constrained sensors is one of the important considerations during communication, use of asymmetric key distribution scheme may not be the perfect choice to achieve secure authentication. Recent research shows that Lucky Thirteen attack has compromised Datagram...
In this paper, we propose using an approach based on the system-level programming language SystemJ extended with service oriented features, called SOSJ, to design dynamic interoperable software systems. The approach abstracts and integrates the worlds of automation and robotics systems by using a simple service interface based on abstract objects within SOSJ. We demonstrate our approach in a real-life...
Current Nyiragongo Volcano observatory systems yield poor monitoring quality due to unpredictable dynamics of volcanic activities and limited sensing capability of existing sensors (seismometers, acoustic microphones, GPS, tilt-meter, optical thermal, and gas flux).The sensor node has limited processing capacity and memory. So if some tasks from the sensor nodes can be uploaded to the server of cloud...
Mobile crowd sensing has the potential to acquire massive data from places and address large-scale societal problems. However, most currently existing crowd sensing systems suffer from insufficient participants. Therefore, incentive design for crowd sensing is essential and urgent. In this paper, different from the auction-based and server-dominant incentives, we design a personalized incentive, PIE,...
Identifying fall risk can prevent injuries in the elderly as well as reduce the related financial burden. A balance assessment, Timed Up and Go (TUG), has been widely applied to estimate fall risk. However, the standardized TUG usually excludes complex factors (e.g. slopes and obstacles) falling short of representing challenges in environments that many older adults navigate. Having information on...
The challenges posed by the Internet of Things (IoT) render existing security measures ineffective against emerging networks and devices. These challenges include heterogeneity, operation in open environments, and scalability. In this paper, we propose SST (Secure Swarm Toolkit), an open-source toolkit for construction and deployment of an authorization service infrastructure for the IoT. The infrastructure...
In this paper, we design an audience-aware signage sensing and interacting system, called Cyber-Physical Ad (CPAd), for individuals using smartphones based on Internet of Things technologies. In the CPAd system, a digital signage can sense surrounding audiences via built-in sensors and the signage content can be adaptive to interact with nearby audiences through real-time multimedia contents. In addition,...
The current growth in Internet services, mobile devices, and machine-to-machine (M2M) technologies is providing the building blocks for the Internet of Things (IoT) as it is being applied across all industry sectors. With ongoing proliferation of IoT applications, a new platform called Fog/edge computing, in addition to Cloud computing, is being developed to address requirements such as bandwidth,...
The progression of cheaper, faster and more reliable Internet technologies leads Internet of Things (IoT) to be applied in various fields of life nowadays. While tremendous data are generated and delivered from IOT devices, it is essential on the server side having scalable and effective data compression techniques to balance storage usage and data precision. This paper presents an adjustable content-sensitive...
For flash flood mitigation, the water level at the upstream river should be measured in a near real time manner to promptly assess the flood risk. In this paper, the water level monitoring telemetry stations have been designed and invented to keep tracking of the river water level. However, there is no electric power supply and no wired communication in the upstream river region. The telemetry station...
Smart devices have many sensors that capture the user data and use it for device control, improving the user experience, or send it through a computer network in order to be processed. The interaction between user and applications, especially in virtual reality, is made via motion and gestures with information offered by sensors such as accelerometer, compass or gyroscope. In order to reduce the complexity...
This paper's purpose is describing and highlighting of how our system is intended to work and how it can help us in everyday life, as well as making the Earth a safer and cleaner place, by not even noticing it's presence. Our system is always monitoring the traffic of every major city, analyzing it and making decisions on how people should drive, in a manner that the roads are safer, the fuel consumption...
This paper is based on the previous research that selects the proper surrogate nodes for fast recovery mechanism in industrial IoT (Internet of Things) Environment which uses a variety of sensors to collect the data and exchange the collected data in real-time for creating added value. We are going to suggest the way that how to decide the number of surrogate node automatically in different deployed...
Open Platform Communication (OPC) also known as Object Linking and Embedding (OLE) for Process Control (OPC) is the platform for communication in automation and manufacturing fields among the group of networked devices. OPC standard supports the group of specifications known as OPC-Data Access (OPC-DA), OPC-Historical Data Access (OPC-HDA) and OPC-Unified Architecture (OPC-UA). In this paper, the...
Recently, several researches concerning with smart and connected communities have been studied. Soon the 4G / 5G technology becomes popular, and cellular base stations will be located densely in the urban space. They may offer intelligent services for autonomous driving, urban environment improvement, disaster mitigation, elderly/disabled people support and so on. Such infrastructure might function...
Internet of Things is capturing attention of consumer and enterprise electronics market with rapid implementations in home automation, smart cities, etc. Several power efficient, low cost sensors have been made available to developers to build these applications. A common theme here is the mode of communication where the computationally intensive work is being done at server side and the sensor-actuator...
