Los nuevos productos y servicios de “Internet de las Cosas” nos harán más eficientes, con una mayor capacidad de actuación y una mejor comprensión de nuestro entorno. Se desarrollarán nuevas ayudas técnicas que permitirán prolongar nuestra vida activa, y muchas ventajas que hoy día nos costaría imaginar. Sin embargo coexistiremos con una gran cantidad de dispositivos que recopilarán información sobre nuestra actividad, costumbres, preferencias, etc., que podrían amenazar nuestra privacidad. La desconfianza que estos riesgos podrían generar en las personas, actuaría como una barrera que podría dificultar el pleno desarrollo de esta nueva gama de productos y servicios. Internet de las Cosas, alcanza su significado más representativo con las Ciudades Inteligentes (Smart Cities) que proporcionan las herramientas necesarias para mejorar la gestión de las ciudades modernas de una manera mucho más eficiente. Estas herramientas necesitan recolectar información de los ciudadanos abriendo la posibilidad de someterlos a un seguimiento. Así, las políticas de seguridad y privacidad deben desarrollarse para satisfacer y gestionar la heterogeneidad legislativa en torno a los servicios prestados y cumplir con las leyes del país en el que se proporcionan estos servicios. El objetivo de esta tesis es aportar una posible solución para la garantizar la seguridad y privacidad de los datos personales en Internet de las Cosas, mediante técnicas que resulten de la colaboración entre las áreas empresarial, legislativa y tecnológica para dar confianza a todos los actores involucrados y resolver la posible colisión de intereses entre ellos, y también debe ser capaz de poder gestionar la heterogeneidad legislativa. Considerando que gran parte de estos servicios se canalizan a través de redes de sensores inalámbricos, y que estas redes tienen importantes limitaciones de recursos, se propone un sistema de gestión que además sea capaz de dar una cobertura de seguridad y privacidad justo a medida de las necesidades. ABSTRACT New products and services offered by the “Internet of Things” will make people more efficient and more able to understand the environment and take better decisions. New assistive technologies will allow people to extend their working years and many other advantages that currently are hard to foreseen. Nonetheless, we will coexist with a large number of devices collecting information about activities, habits, preferences, etc. This situation could threaten personal privacy. Distrust could be a barrier to the full development of these new products and services. Internet of Things reaches its most representative meaning by the Smart Cities providing the necessary solutions to improve the management of modern cities by means of more efficient tools. These tools require gathering citizens’ information about their activity, preferences, habits, etc. opening up the possibility of tracking them. Thus, privacy and security policies must be developed in order to satisfy and manage the legislative heterogeneity surrounding the services provided and comply with the laws of the country where they are provided. The objective of this thesis is to provide a feasible solution to ensure the security and privacy of personal data on the Internet of Things through resulting techniques from the collaboration between business, legislative and technological areas so as to give confidence to all stakeholders and resolve the possible conflict of interest between them, as well as to manage the legislative heterogeneity. Whereas most of these services are based on wireless sensor networks, and these networks have significant resource constraints, the proposed management system is also able to cover the security and privacy requirements considering those constrains.

There is a growing concern about the poor quality of the writing of children and teenagers because of the continuous and constant exposure to the new technologies. Increasingly parents complain that their children spend too much time with their phones, tablets, computers, video games, etc. There is also an increase in the number of teachers who complain about their students’ writing skills. Some of the most prominent criticisms are loss of vocabulary, simplified syntax and the poor spelling of the compositions. To verify if these criticisms are motivated or not by the use of information and communication technologies (ICT) is what moved us to initiate this doctoral dissertation entitled “The influence of ICT on ratings of syntactic maturity: a comparative study between pre- and post-internet generations”. We aim to know if a daily and constant exposure to the ICT can affect the syntactic maturity rates of children and teenagers. We also want to find out if there are differences between the levels of syntactic maturity of today’s students and those of the 1990s, when there were no ICT and internet. In order to do this, we have carried out a quantitative analysis taking as a reference previous studies by generativist researchers in the Anglo-Saxon and Hispanic world and we have used the same units of measure (T-unit and clause). We collected a corpus of 382 essays, half argumentative and half descriptive, from 191 individuals. We have analyzed them according to ten dependent variables or syntactic maturity rates and other independent variables (Hours in internet, Course, Sex, Location, Type of school) by applying techniques of descriptive and inferential statistics...

Business Intelligence (BI) applications have been gradually ported to the Web in search of a global platform for the consumption and publication of data and services. On the Internet, apart from techniques for data/knowledge management, BI Web applications need interfaces with a high level of interoperability (similar to the traditional desktop interfaces) for the visualisation of data/knowledge. In some cases, this has been provided by Rich Internet Applications (RIA). The development of these BI RIAs is a process traditionally performed manually and, given the complexity of the final application, it is a process which might be prone to errors. The application of model-driven engineering techniques can reduce the cost of development and maintenance (in terms of time and resources) of these applications, as they demonstrated by other types of Web applications. In the light of these issues, the paper introduces the Sm4RIA-B methodology, i.e., a model-driven methodology for the development of RIA as BI Web applications. In order to overcome the limitations of RIA regarding knowledge management from the Web, this paper also presents a new RIA platform for BI, called RI@BI, which extends the functionalities of traditional RIAs by means of Semantic Web technologies and B2B techniques. Finally, we evaluate the whole approach on a case study—the development of a social network site for an enterprise project manager.

La gran cantidad de información disponible en Internet está dificultando cada vez más que los usuarios puedan digerir toda esa información, siendo actualmente casi impensable sin la ayuda de herramientas basadas en las Tecnologías del Lenguaje Humano (TLH), como pueden ser los recuperadores de información o resumidores automáticos. El interés de este proyecto emergente (y por tanto, su objetivo principal) viene motivado precisamente por la necesidad de definir y crear un marco tecnológico basado en TLH, capaz de procesar y anotar semánticamente la información, así como permitir la generación de información de forma automática, flexibilizando el tipo de información a presentar y adaptándola a las necesidades de los usuarios. En este artículo se proporciona una visión general de este proyecto, centrándonos en la arquitectura propuesta y el estado actual del mismo.

The sustainability strategy in urban spaces arises from reflecting on how to achieve a more habitable city and is materialized in a series of sustainable transformations aimed at humanizing different environments so that they can be used and enjoyed by everyone without exception and regardless of their ability. Modern communication technologies allow new opportunities to analyze efficiency in the use of urban spaces from several points of view: adequacy of facilities, usability, and social integration capabilities. The research presented in this paper proposes a method to perform an analysis of movement accessibility in sustainable cities based on radio frequency technologies and the ubiquitous computing possibilities of the new Internet of Things paradigm. The proposal can be deployed in both indoor and outdoor environments to check specific locations of a city. Finally, a case study in a controlled context has been simulated to validate the proposal as a pre-deployment step in urban environments.
