The development of the Internet has made it possible to transfer data ‘around the globe at the click of a mouse’. Especially fresh business models such as cloud computing, the newest driver to illustrate the speed and breadth of the online environment, allow this data to be processed across national borders on a routine basis. A number of factors cause the Internet to blur the lines between public and private space: Firstly, globalization and the outsourcing of economic actors entrain an ever-growing exchange of personal data. Secondly, the security pressure in the name of the legitimate fight against terrorism opens the access to a significant amount of data for an increasing number of public authorities.And finally,the tools of the digital society accompany everyone at each stage of life by leaving permanent individual and borderless traces in both space and time. Therefore, calls from both the public and private sectors for an international legal framework for privacy and data protection have become louder. Companies such as Google and Facebook have also come under continuous pressure from governments and citizens to reform the use of data. Thus, Google was not alone in calling for the creation of ‘global privacystandards’. Efforts are underway to review established privacy foundation documents. There are similar efforts to look at standards in global approaches to privacy and data protection. The last remarkable steps were the Montreux Declaration, in which the privacycommissioners appealed to the United Nations ‘to prepare a binding legal instrument which clearly sets out in detail the rights to data protection and privacy as enforceable human rights’. This appeal was repeated in 2008 at the 30thinternational conference held in Strasbourg, at the 31stconference 2009 in Madrid and in 2010 at the 32ndconference in Jerusalem. In a globalized world, free data flow has become an everyday need. Thus, the aim of global harmonization should be that it doesn’t make any difference for data users or data subjects whether data processing takes place in one or in several countries. Concern has been expressed that data users might seek to avoid privacy controls by moving their operations to countries which have lower standards in their privacy laws or no such laws at all. To control that risk, some countries have implemented special controls into their domestic law. Again, such controls may interfere with the need for free international data flow. A formula has to be found to make sure that privacy at the international level does not prejudice this principle.

Applying location-focused data protection law within the context of a location-agnostic cloud computing framework is fraught with difficulties. While the Proposed EU Data Protection Regulation has introduced a lot of changes to the current data protection framework, the complexities of data processing in the cloud involve various layers and intermediaries of actors that have not been properly addressed. This leaves some gaps in the regulation when analyzed in cloud scenarios. This paper gives a brief overview of the relevant provisions of the regulation that will have an impact on cloud transactions and addresses the missing links. It is hoped that these loopholes will be reconsidered before the final version of the law is passed in order to avoid unintended consequences.

Cloud computing provides a promising solution to the genomics data deluge problem resulting from the advent of next-generation sequencing (NGS) technology. Based on the concepts of “resources-on-demand” and “pay-as-you-go”, scientists with no or limited infrastructure can have access to scalable and cost-effective computational resources. However, the large size of NGS data causes a significant data transfer latency from the client’s site to the cloud, which presents a bottleneck for using cloud computing services. In this paper, we provide a streaming-based scheme to overcome this problem, where the NGS data is processed while being transferred to the cloud. Our scheme targets the wide class of NGS data analysis tasks, where the NGS sequences can be processed independently from one another. We also provide the elastream package that supports the use of this scheme with individual analysis programs or with workflow systems. Experiments presented in this paper show that our solution mitigates the effect of data transfer latency and saves both time and cost of computation.

Managing large medical image collections is an increasingly demanding important issue in many hospitals and other medical settings. A huge amount of this information is daily generated, which requires robust and agile systems. In this paper we present a distributed multi-agent system capable of managing very large medical image datasets. In this approach, agents extract low-level information from images and store them in a data structure implemented in a relational database. The data structure can also store semantic information related to images and particular regions. A distinctive aspect of our work is that a single image can be divided so that the resultant sub-images can be stored and managed separately by different agents to improve performance in data accessing and processing. The system also offers the possibility of applying some region-based operations and filters on images, facilitating image classification. These operations can be performed directly on data structures in the database.

En el campo de la biomedicina se genera una inmensa cantidad de imágenes diariamente. Para administrarlas es necesaria la creación de sistemas informáticos robustos y ágiles, que necesitan gran cantidad de recursos computacionales. El presente artículo presenta un servicio de cloud computing capaz de manejar grandes colecciones de imágenes biomédicas. Gracias a este servicio organizaciones y usuarios podrían administrar sus imágenes biomédicas sin necesidad de poseer grandes recursos informáticos. El servicio usa un sistema distribuido multi agente donde las imágenes son procesadas y se extraen y almacenan en una estructura de datos las regiones que contiene junto con sus características. Una característica novedosa del sistema es que una misma imagen puede ser dividida, y las sub-imágenes resultantes pueden ser almacenadas por separado por distintos agentes. Esta característica ayuda a mejorar el rendimiento del sistema a la hora de buscar y recuperar las imágenes almacenadas.

Los continuos avances tecnológicos están trayendo consigo nuevas formas de almacenar, tratar y comunicar datos personales. Es necesario repensar el derecho fundamental a la protección de datos, y arbitrar mecanismos para adaptarlo a las nuevas formas de tratamiento. a nivel europeo se está trabajando en una nueva propuesta de regulación que consideramos, en general, muy apropiada para afrontar los nuevos retos en esta materia. para ejemplificar todo esto, en el presente estudio se plantea de forma detallada el caso de la computación en nube, sus principales características y algunas preocupaciones acerca de los riesgos potenciales que su utilización trae consigo. Abstract: Rapid technological developments are bringing new ways to store, process and communicate personal data. We need to rethink the fundamental right to data protection and adapt it to new forms of treatment. there is a new «european» proposal for a regulation on the protection of individuals with regard to the processing of personal data, well suited to meet the new challenges. this study offers one example of this: the cloud computing, its main characteristics and some concerns about the potential risks that its use entails.

Low resources in many African locations do not allow many African scientists and physicians to access the latest advances in technology. This deficiency hinders the daily life of African professionals that often cannot afford, for instance, the cost of internet fees or software licenses. The AFRICA BUILD project, funded by the European Commission and formed by four European and four African institutions, intends to provide advanced computational tools to African institutions in order to solve current technological limitations. In the context of AFRICA BUILD we have carried out, a series of experiments to test the feasibility of using Cloud Computing technologies in two different locations in Africa: Egypt and Burundi. The project aims to create a virtual platform to provide access to a wide range of biomedical informatics and learning resources to professionals and researchers in Africa.

Access to information and continuous education represent critical factors for physicians and researchers over the world. For African professionals, this situation is even more problematic due to the frequently difficult access to technological infrastructures and basic information. Both education and information technologies (e.g., including hardware, software or networking) are expensive and unaffordable for many African professionals. Thus, the use of e-learning and an open approach to information exchange and software use have been already proposed to improve medical informatics issues in Africa. In this context, the AFRICA BUILD project, supported by the European Commission, aims to develop a virtual platform to provide access to a wide range of biomedical informatics and learning resources to professionals and researchers in Africa. A consortium of four African and four European partners work together in this initiative. In this framework, we have developed a prototype of a cloud-computing infrastructure to demonstrate, as a proof of concept, the feasibility of this approach. We have conducted the experiment in two different locations in Africa: Burundi and Egypt. As shown in this paper, technologies such as cloud computing and the use of open source medical software for a large range of case present significant challenges and opportunities for developing countries, such as many in Africa.

Las últimas previsiones de mercado el cloud computing pronostican un crecimiento anual del 30%, ya que cada vez más personas adoptan la tecnología más avanzada para almacenar información en un espacio virtual. Sin embargo, el cloud computing no es sólo un sistema de almacenamiento de datos, sino que también se puede utilizar para ejecutar software y aplicaciones de forma remota, sin estar atado a un único ordenador. Para una pequeña empresa, la externalización de TI a la nube reduce la necesidad de contratar personas con habilidades especializadas y libera a los directores para que puedan concentrarse en el negocio. En el segundo capítulo analizamos el estado del arte del cloud computing, para lo cual en primer lugar definimos qué es cloud, así como cuáles son sus ventajas e inconvenientes. Presentamos los diferentes modelos de cloud computing, y cuáles son sus principales proveedores actualmente. Para finalizar esbozamos unas pinceladas del siempre complejo marco regulatorio del cloud computing en España. En el Capítulo 3 presentamos la situación de las pequeñas y medianas empresas dentro del ecosistema empresarial español, basándonos en los datos proporcionados por el Instituto Nacional de Estadística del año 2013. A continuación, en el Capítulo 4, analizamos la penetración del Cloud Computing en España, desde el punto de vista que tienen las pequeñas empresas de las tecnologías cloud, así como del uso que estas hacen del mismo. Para este capítulo hemos utilizado el informe realizado por Deloitte para el Ministerio de Industria, Energía y Turismo. En el capítulo 5 veremos un caso real de solución software as a service, desarrollado por mi empresa. Se trata de una aplicación de gestión de activos inmobiliarios, que enfocaremos hacia las pequeñas inmobiliarias. Para ello analizaremos la tipología de Pyme hacia la que queremos dirigir el producto viendo en detalle el sector de las actividades inmobiliarias, así como describiremos qué tipo de aplicación es y su funcionalidad (de modo muy resumido consiste en la gestión del ciclo de venta de todos los inmuebles de una agencia inmobiliaria, desde que el cliente solicita una visita, hasta que se lleva a cabo la firma de las escrituras). Posicionaremos el producto en precio y haremos una comparativa entre otras soluciones tanto cloud como on-premise para comparar su ventaja competitiva en precio. A continuación describiremos cómo pensamos hacer la comunicación del producto, mediante la publicación de la aplicación en el App Exchange de Salesforce, ferias inmobiliarias, etc y describiremos los servicios de valor añadido que ofrecemos. Por último estableceremos las previsiones económicas a tres años de las ventas del producto. Por último en el Capítulo 6 concluiremos el proyecto con una serie de reflexiones sobre los retos y las oportunidades a las que se enfrentan las Pymes actualmente, en lo que se refiere a la implantación de sistemas en la nube, y más concretamente los retos y oportunidades que pueden tener las Pymes el sector inmobiliario con las soluciones cloud.

Currently, student dropout rates are a matter of concern among universities. Many research studies, aimed at discovering the causes, have been carried out. However, few solutions, that could serve all students and related problems, have been proposed so far. One such problem is caused by the lack of the "knowledge chain educational links" that occurs when students move onto higher studies without mastering their basic studies. Most regulated studies imparted at universities are designed so that some basic subjects serve as support for other, more complicated, subjects, thus forming a complicated knowledge network. When a link in this chain fails, student frustration occurs as it prevents him from fully understanding the following educational links. In this proposal we try to mitigate these disasters that stem, for the most part, the student?s frustration beyond his college stay. On one hand, we make a dissertation on the student?s learning process, which we divide into a series of phases that amount to what we call the "learning lifecycle." Also, we analyze at what stage the action by the stakeholders involved in this scenario: teachers and students; is most important. On the other hand, we consider that Information and Communication Technologies ICT, such as Cloud Computing, can help develop new ways, allowing for the teaching of higher education, while easing and facilitating the student?s learning process. But, methods and processes need to be defined as to direct the use of such technologies; in the teaching process in general, and within higher education in particular; in order to achieve optimum results. Our methodology integrates, as another actor, the ICT into the "Learning Lifecycle". We stimulate students to stop being merely spectators of their own education, and encourage them to take an active part in their training process. To do this, we offer a set of useful tools to determine not only academic failure causes, (for self assessment), but also to remedy these failures (with corrective actions); "discovered the causes it is easier to determine solutions?. We believe this study will be useful for both students and teachers. Students learn from their own experience and improve their learning process, while obtaining all of the "knowledge chain educational links? required in their studies. We stand by the motto "Studying to learn instead of studying to pass". Teachers will also be benefited by detecting where and how to strengthen their teaching proposals. All of this will also result in decreasing dropout rates.

It has been shown that cloud computing brings cost benefits and promotes efficiency in the operations of the organizations, no matter what their type or size. However, few public organizations are benefiting from this new paradigm shift in the way the organizations consume and manage computational resources. The objective of this thesis is to analyze both internal and external factors that may influence the adoption of cloud computing by public organizations and propose possible strategies that can assist these organizations in their path to cloud usage. In order to achieve this objective, a SWOT analysis has been conducted, detecting internal factors (strengths and weaknesses) and external factors (opportunities and threats) that can influence the adoption of a governmental cloud. With the application of a TOWS matrix, by combining the internal and external factors, a list of possible strategies have been formulated to be used as a guide to decision-making related to the transition to a cloud environment.
