Dissertação (Mestrado em Ciência da Computação) - Universidade Federal de Goiás, Goiânia, 2019.http://repositorio.bc.ufg.br/tede/handle/tede/9323In the Internet of Things (IoT) paradigm, real-world objects equipped with identification, detection, network, and processing capabilities communicate and consume services over the Internet to perform some task on behalf of users. Due to the growing popularization of devices with sensing capabilities and the consequent increase in data production from these devices, the literature states that the design of an ontology-based model is an essential starting point for addressing privacy risks in IoT, since the connected devices are increasingly able to monitor human activities. In addition, due to the complexity and dynamicity of IoT environments, we emphasize the need for privacy ontologies that combine expressive and extensible vocabulary but do not overload the processing of privacy data. Facing this problem, this work presents the development of an ontology-based solution for privacy in IoT, composed by: i) IoT-Priv, a privacy ontology for IoT, built as a light layer on IoT concepts imported from an emerging ontology, called IoTLite; and ii) IoT-PrivServ, a privacy management service, which provides functionalities for consumers and / or producers who use the IoT-Priv ontology in modeling their data, abstracting from them the complexity of perform such tasks. As contributions, the results of the evaluation of IoT-Priv and IoT-PrivServ indicate that we maintained the lightness characteristic present in IoT-Lite, which was one of our initial goals. In addition, we have demonstrated that IoT-Priv is expressive and extensible, since its concepts allow complex scenarios to be modeled, and if necessary, the extension points included in the ontology allow it to be imported and extended to meet more specific needs.application/pdfAcesso AbertoInternet das CoisasPrivacidadeOntologiaServiço de gerenciamentoWeb semânticaInternet of ThingsOntologyManagement serviceSemantic WebPrivacyCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAODissertação
