In smart factories and smart homes, devices such as smart sensors are connected to the Internet. Independent of the context in which such a smart sensor is deployed, the possibility to change its configuration parameters in a secure way is essential. Existing solutions do provide only minimal security or do not allow to transfer arbitrary configuration data. In this paper, we present an NFC- and QR-code...
We propose a user-centric private key management framework that supports future personal sensing applications. This framework allows for a simple distributed private key system with embedded secure key storage and recovery in multiple parties. The user maintains control over implementation choices and the ability to consent to data being utilised or transmitted by the system. Our proposed framework...
The Home Subscriber Server (HSS) within the packet core of the Long Term Evolution (LTE) is a key node leveraged for essential operations, such as mutual authentication and access control. This centralized node is essential for the overall network operation as it is the cornerstone of the cryptographic functions executed in a mobile network. It stores several parameters for each subscriber, including...
The work presents a Multi-Agent System (MAS) solution for generating personalized recommendations on mobile devices with the use of contextual data acquired from the Internet of Thing (IoT). For mass data processing and personalized model preparation a server-side MAS architecture for Big Data processing is used. In order to deliver context-aware recommendations for very sparse input data, based on...
This paper discusses the notion of self-organising and context-aware data flows, i.e. spatially-situated services made of flows of data propagating across mobile nodes, sensitive to their context and responding to it following self-organising principles. This paves the way for a new category of spatially-situated pervasive services based on data propagation among mobile devices.
Emerging context frameworks enable Websites to interact with the Internet of Things directly from the browser; however, Websites must be specifically designed to utilize such context framework support. As such, the majority of “legacy” Websites remains context-unaware. This paper presents Ambient Amp, an open framework for dynamically augmenting legacy Websites with context-awareness, without requiring...
With the development of sensing, wireless communication, and Internet technologies, we are now living in a world that is filled with various smart things ¨C the Internet of Things. This paper introduces and prospects an emerging research area ¨C Embedded Intelligence (EI), which aims at revealing the individual behaviors, spatial contexts, as well as social patterns and urban dynamics by mining the...
In dynamic environments, interactivities with smart objects can be complex for accomplishing particular activities or procedures. Ideally, interaction paradigms for smart objects should naturally adhere to the ethos of ubiquitous computing; however, it hasn't been fully achieved yet due to the lack of general and intuitive mechanisms in dealing with heterogeneous objects. The major challenges of assuring...
Mobile phones are increasingly able to read auto-id labels, such as barcodes or RFID tags. As virtually all consumer products sold today are equipped with such a label, this opens the possibility for a wide range of novel digital services building on physical products. In this paper, we discuss the problems that arise when such novel applications are deployed, and present a unified system architecture...
In this paper a model for the development of context-awareness applications using Near Field Communication is presented. The model is based in the association of services and resources to augmented objects through Tags. The different types of services assigned to the objects are modeled in a hierarchy defining the execution order and personalizing the user interaction through the use of resources...
