A Test Environment for Wireless Hacking in Domestic IoT Scenarios

Security is gaining importance in the daily life of every citizen. The advent of Internet of Things devices in our lives is changing our conception of being connected through a single device to a multiple connection in which the centre of connection is becoming the devices themselves. This conveys the attack vector for a potential attacker is exponentially increased. This paper presents how the concatenation of several attacks on communication protocols (WiFi, Bluetooth LE, GPS, 433 Mhz and NFC) can lead to undesired situations in a domestic environment. A comprehensive analysis of the protocols with the identification of their weaknesses is provided. Some relevant aspects of the whole attacking procedure have been presented to provide some relevant tips and countermeasures.This work has been partially supported by the Spanish Ministry of Science and Innovation through the SecureEDGE project (PID2019-110565RB-I00), and by the by the Andalusian FEDER 2014-2020 Program through the SAVE project (PY18-3724). // Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature. // Funding for open access charge: Universidad de Málaga / CBU

Perspectives and approaches for the internet of things

Dissertação para obtenção do Grau de Mestre em Engenharia Electrotécnica e de ComputadoresThis thesis was developed based on a scenario in which a CEO of a certain company asked the author to conduct an exploratory work evaluating the potential opportunities and limitations of this emerging area described as the future of the Internet, the Internet of Things (IoT). The objective is thus to provide the reader with a wide view of the vital points for the implementation and exploitation of the IoT, a technology that promises to deliver a new and wider range of applications to the society. In this subject there is a need to gather and organize information produced by several researchers and contributors. Due to the fact of being a new area and researchers work independently of each other, the work is scattered and inconsistencies can be found among different projects and publications. As such, in a first stage some definitions are provided and an attempt to clarify concepts is made. To support and emphasize the exponential growth of IoT, a brief historical overview is provided to the reader. This overview is based on the new trends and expectations that arise every day through news, potential businesses and also in important tools such as Google Trends. Several examples of applications in the context of the IoT, illustrate the benefits, not only in terms of society, but also for business opportunities, safety, and well-being. The main areas of interest to achieve the IoT such as: hardware, software, modeling, methods of connection, security and integration are studied in this work, in order to provide some insight into current strong and weak points. As the Internet of Things become a matter of large interest, various research groups are active in exploring and organizing projects in this area. Some of these projects, namely the ones considered the most important, are also presented in this thesis. Taking into account the facts surrounding this new technology, it becomes quite important to bring them together, clarifying them and trying to open new perspectives for further studies and improvements. Finally, in order to allow a practical evaluation of the technology, a prototype is developed around the connection of an intelligent object – a small mobile robot – to the Internet. A set of conclusions and future work directions are then presented which take into account the findings of the bibliographic analysis as well as the acquired experience with the implementation of the prototype

Creating Value By Object Hyperlinking Along The Consumer Buying Decision Process In The IoT Era

Within the IoT scope, a new application named ‘object hyperlinking’ has evolved. Object hyperlinking is the pervasive presence of different things or objects identified by tags, sensors, and mobile phones that can interact with each other as well as with their neighbors through unique addressing schemes for business purpose. Enabled by Automatic Identification and Data Capture (AIDC) technologies such as QR code and NFC, object hyperlinking services make it possible link any object or location to a more comprehensive and editable information. While tagging technologies have good prospects to offer more opportunities in a company’s interaction with its consumers, how this capability can be best applied and what innovative business services be created with object hyperlinking remain to be discovered. This study surveys and examines 76 projects of object hyperlinking in Taiwan and provides a framework to figure out business value and issues of object hyperlinking along the five stages of a consumer buying decision process. Based on the functionality and purpose of object hyperlinking services, this framework is conducted in dimensions of value creation, value orientation, functionality, key factor and challenges, key activities within organization, and managerial issues concerned. Some innovative business models enabled by object hyperlinking will also be introduced. The research results found that only when the information gathered by identified objects is used, analyzed, and distributed into wide business activities in term of marketing, customer service and firm level strategy planning, the effectiveness and value of object hyperlinking services can be realized at its maximum. The integration across different consumer buying decision process is also important. The more applications of object hyperlinking in different buying decisions, the more benefits will be created for customers. Managers can use the list of dimensions proposed in the framework to develop rich IoT business from enhancing service operations with object hyperlinking

Situational awareness through IoT sensors : A smart healthcare system as a use case

Emerging technologies of the Internet of Things are getting increasingly significant and to some extent essential as well to the society we are living in. These technologies have shown ability over the time to be implemented in a number of different fields, for instance, Smart Home, Smart Building, Smart City, Smart Retail, Smart Supply Chain, Smart Farming, Smart Grid, Industrial Internet and many more. Incorporation of Internet of Things technologies in the healthcare sector has potential to benefit not only medical related enterprises but at the same time it can improve the overall health and well-being of individuals as well. The deployment of IoT integrated systems has to deal with fairly heterogeneous environments that consist of a large number of sensors and actuators which all can be quite different from one another in many aspects. For example, they can use different operating systems and can have different hardware architecture. Such sensors are sometimes used for situational awareness of the surrounding and for making the individuals interact better with their environment. Such variety of applications and tasks poses a problem for system designers and developers on the choice of the most suitable technology to be employed to accomplish a specific task. This thesis explores the potential of Internet of Things technologies in the medical sector. We used analytical hierarchical process to have a kind of situational awareness through IoT technologies. As an use case, a healthcare system was considered for elderly people with neurological problems who need special care – people suffering with dementia for example. At the same time we have taken into account for the proposed system that it would enable regular people track and monitor their usual activities with a focus on improving the quality of life and enhancing their overall wellbeing. It is of prime importance for the system designers and developers that they have an idea about the potential IoT technologies and applications that can help this cause. We have considered eleven different IoT technologies to select from for the proposed paradigm. The decision of selecting the most appropriate technology obviously depends upon different criteria. Every IoT technology has its pros and cons. According to the needs of the proposed healthcare system, we have constructed a multi-criteria hierarchical model to assess the potential of those eleven IoT technologies for the healthcare system and chosen the best one based on set criteria and sub criteria. A 4-tier Analytical Hierarchical model is used to compare those technologies in terms of their quality of service or effectiveness, their acceptability and from the cost perspective. These criteria are then further divided into sub-criteria and the technologies are compared with respect to these ten sub-criteria to have a more thorough and comprehensive analysis. For these comparisons, quantitative data were collected from the internet including IEEE articles, and some of the comparisons are purely subjective. The results indicate that wide-area low-power solutions show more potential for the proposed healthcare system than other IoT technologies which we used for comparison, and SigFox tops the table. Also WiFi solutions have shown significant potential. But again, every technology has its shortcomings as well. Further studies are needed to see if we can somehow make a hybrid healthcare system that utilizes multiple IoT technologies and incorporate the plus points of all of them into the system; such future system can prove to be revolutionary in the medical care

IoT and blockchain paradigms for EV charging system

In this research work, we apply the Internet of Things (IoT) paradigm with a decentralized blockchain approach to handle the electric vehicle (EV) charging process in shared spaces, such as condominiums. A mobile app handles the user authentication mechanism to initiate the EV charging process, where a set of sensors are used for measuring energy consumption, and based on a microcontroller, establish data communication with the mobile app. A blockchain handles financial transitions, and this approach can be replicated to other EV charging scenarios, such as public charging systems in a city, where the mobile device provides an authentication mechanism. A user interface was developed to visualize transactions, gather users’ preferences, and handle power charging limitations due to the usage of a shared infrastructure. The developed approach was tested in a shared space with three EVs using a charging infrastructure for a period of 3.5 months.info:eu-repo/semantics/publishedVersio

mHealth: monitoring platform for diabetes patients

Diabetes is a metabolic disease that can be explained by the high level of glucose in the blood. Constant monitoring of patients with this type of disease is crucial to the success of their treatment due to the high number of factors that condition it, such as nutrition, exercise and insulin production. This research consists of a software development project based on mHealth practice, which aims to cover all the needs of patients and health professionals, introducing improvements in the prevention, diagnosis and control of endocrine pathology, as well as improvements in hospital management. The web platform should be able to send a warning to the healthcare professional in cases where a patient's recorded level exceeds normal values and contain all the patient's records. The aim is to provide support to treatment, monitoring and data collection based on IoT principles, where medical devices allow communication between machines and interaction between them, sharing and managing data. The healthcare professional will have the necessary information to assess the health status of his patient and, if necessary, make some changes to improve the patient's daily routines.This work has been supported by FCT – Fundação para a Ciência e Tecnologia within the R&D Units Project Scope: UIDB/00319/2020
