Sistemas de pago emergentes con móvil

Los sistemas de pago con móvil son una alternativa de pago a los medios de pago electrónicos tradicionales que están siendo cada vez más utilizados en nuestra sociedad. Son varios los factores que han llevado a la utilización de esta forma alternativa de pago. Los terminales móviles se han convertido en una herramienta casi vital para la sociedad, lo cual ha contribuido a una gran aceptación y desarrollo de los terminales móviles que cada vez cuentan con más funcionalidades. Gracias a esto, las comunicaciones móviles también están en constante evolución y ello ha influido notablemente para que se puedan desarrollar nuevos servicios e implementar nuevas funcionalidades en los terminales móviles. Por otro lado, la tendencia de los usuarios a usar cada día más los sistemas de pago electrónicos, intentando en la medida de lo posible prescindir del dinero en efectivo, también es un factor que ha permitido impulsar el desarrollo de este tipo de sistema de pagos emergentes. En el otro lado se encuentra el mundo empresarial, donde por un lado están las empresas de telecomunicaciones que no quieren dejar escapar esta oportunidad de negocio y están invirtiendo dinero para desarrollar nuevas infraestructuras que permitan el pago con móvil, y por otro lado se encuentran las entidades financieras que son necesarias para poder llevar a cabo los pagos a través del móvil, y por tanto tienen que formar parte de la solución llegando a los acuerdos necesarios con los proveedores de servicios. En este trabajo se realiza un análisis de las diferentes plataformas de pago por móvil existentes en la actualidad, prestando especial atención a los aspectos que tienen que ver con la seguridad y la disponibilidad y acceso de la información bancaria del usuario. Asimismo también se analiza la arquitectura de cada plataforma como su funcionamiento, aclarando la interacción y el papel que juegan las diferentes partes implicadas. Para ello hay un capítulo dedicado a la seguridad donde se presentan conceptos y protocolos que son aplicados en las soluciones de pagos electrónicos, y una descripción de los sistemas de pago electrónicos más usados actualmente, los cuales presentan muchas similitudes con los sistemas de pago con móvil. Por último se recogen diferentes experiencias llevadas a cabo en nuestro país de pagos con móvil, destacando la experiencia de los usuarios así como el método empleado. ABSTRACT. Mobile payment systems are payment methods alternative to traditional electronic payment ones that are being increasingly used in our society. Several factors have led to the use of this alternative form of payment. Mobile terminals have become almost a vital tool for society, which has contributed to a wide acceptance and development of mobile terminals that are getting more features all the time. As a result, mobile communications are also evolving and they have had such a great influence that they have developed new services and implemented new features in mobile terminals. What is more, the growing tendency among users to use electronic payment systems, trying to make their payments whithout cash as often as possible, is also a factor that has allowed the boost the development of such emerging payment systems. The other partner of these systems is the business world, where on one hand, the telecommunication companies that do not want to miss this business opportunity are investing funds to develop new infrastructures which enable the mobile payment, and on the other hand, the financial institutions that are necessary to carry out payments via mobile, and therefore need to be part of the solution reaching the necessary agreements with service providers, want their own saying and their own share of the potential profits. This report is an analysis of the different mobile payment platforms existing today, with particular attention to the aspects that have to do with security and the availability and acces of user’s bank information. Likewise, it also analyzes the architecture of each platform and its operation and interaction procedures, clarifying the role of the different parties involved. Previously there is a chapter that presents security concepts and protocols that are applied in electronic payment solutions, and a description of the electronic trade systems most widely used currently, which have many similarities with mobile payment systems. Finally, it shows different experiments carried out in our country of mobile payments, highlighting the experience of users as well as the method used.

Modelado de un servicio de M-Salud basado en dinámica de sistemas

En términos generales, m-salud puede definirse como el conjunto de sistemas de información, sensores médicos y tecnologías de comunicaciones móviles para el cuidado de la salud. La creciente disponibilidad, miniaturización, comportamiento, velocidades de transmisión de datos cada vez mayores y la esperada convergencia de tecnologías de red y comunicaciones inalámbricas en torno a los sistemas de salud móviles están acelerando el despliegue de estos sistemas y la provisión de servicios de m-salud, como por ejemplo, la teleasistencia móvil. El concepto emergente de m-salud conlleva retos importantes (estudios técnicos, análisis, modelado de la provisión de servicios, etc.) que hay que afrontar para impulsar la evolución de los sistemas y servicios de e-salud ofrecidos desde tecnologías de telecomunicación que utilizan acceso por cable y redes fijas, hacia configuraciones móviles e inalámbricas de última generación. En este trabajo se analizará primeramente el significado e implicaciones de m-salud y la situación en la que se encuentra; los retos a los que hay que enfrentarse para su implantación y provisión así como su tendencia. De los múltiples y diferentes servicios que se pueden proveer se ha identificado el servicio de Localización de Personas LoPe, lanzado por Cruz Roja en febrero de 2007, para teleasistencia móvil y que permite conocer en todo momento la ubicación de la persona que porta su dispositivo asociado. Orientado a personas con discapacidad, en situación de riesgo o dependencia por deterioro cognitivo, tiene como objetivo ayudarlas a recuperar su autonomía personal. La provisión de este servicio se modelará mediante dinámica de sistemas, ya que esta teoría se considera idónea para modelar sistemas complejos que evolucionan con el tiempo. El resultado final es un modelo que implementado a través de la herramienta Studio 8® de la compañía noruega Powersim Software AS nos ha permitido analizar y evaluar su comportamiento a lo largo del tiempo, además de permitirnos extraer conclusiones sobre el mismo y plantear futuras mejoras sobre el servicio. ABSTRACT. In general terms, m-health can be defined as “mobile computing, medical sensor, and communications technologies for health care.” The increased availability, miniaturization, performance, enhanced data rates, and the expected convergence of future wireless communication and network technologies around mobile health systems are accelerating the deployment of m-health systems and services, for instance, mobile telecare. The emerging concept of m-health involves significant challenges (technical studies, analysis, modeling of service provision, etc.) that must be tackled to drive the development of e-health services and systems offered by telecommunication technologies that use wired and fixed networks towards wireless and mobile new generation networks. Firstly, in this master’s thesis, the meaning and implications of m-health and its current situation are analyzed. This analysis also includes the challenges that must be tackled for the implementation and provision of m-health technologies and services and the m-health trends. Among the many different m-health services already delivered, the Localización de Personas LoPe service has been identified to work with it. This service, launched by Spanish Red Cross in February 2007, enables to locate people who carry the associated device. It’s aimed at people with disabilities, at risk or dependency due to cognitive impairment and helps them to recover their personal autonomy. The provision of this service will be modeled with system dynamics considering that this theory suits very well the modeling of complex systems which evolve over time. The final result is a system dynamics model of the service implemented with Studio 8® tool developed by Powersim Software AS, a Norwegian company. This model has allowed us to analyze and evaluate its behaviour over time, as well as to draw conclusions and to consider some future improvements in the service.

Wirecloud Mobile: soporte para el enriquecimiento y la visualización de mashups de aplicación en dispositivos móviles

El mundo actual es una fuente ilimitada de información. El manejo y análisis de estas enormes cantidades de información es casi imposible, pero también es difícil poder capturar y relacionar diferentes tipos de datos entre sí y, a partir de este análisis, sacar conclusiones que puedan conllevar a la realización, o no, de un conjunto de acciones. Esto hace necesario la implementación de sistemas que faciliten el acceso, visualización y manejo de estos datos; con el objetivo de poder relacionarlos, analizarlos, y permitir al usuario que, de la manera más sencilla posible, pueda sacar conclusiones de estos. De esta necesidad de manejar, visualizar y relacionar datos nació la plataforma Wirecloud. Wirecloud ha sido desarrollado en el laboratorio Computer Networks & Web Technologies Lab (CoNWeT Lab) del grupo CETTICO, ubicado en la Escuela Técnica Superior de Ingenieros Informáticos de la Universidad Politécnica de Madrid. Wirecloud es una plataforma de código abierto que permite, utilizando las últimas tecnologías web, recoger la información que se quiere analizar de diferentes fuentes en tiempo real e, interconectando entre sí una serie de componentes y operadores, realizar una mezcla y procesado de esta información para después usarla y mostrarla de la manera más usable posible al usuario. Un ejemplo de uso real de la plataforma podría ser: utilizar la lista de repartidores de una empresa de envío urgente para conocer cuáles son sus posiciones en tiempo real sobre un mapa utilizando el posicionamiento GPS de sus dispositivos móviles, y poder asignarles el destino y la ruta más óptima; todo esto desde la misma pantalla. El proyecto Wirecloud Mobile corresponde a la versión móvil de la plataforma Wirecloud, cuyo objetivos principales pretenden compatibilizar Wirecloud con el mayor número de sistemas operativos móviles que actualmente hay en el mercado, permitiendo su uso en cualquier parte del mundo; y poder enriquecer los componentes mencionados en el párrafo anterior con las características y propiedades nativas de los dispositivos móviles actuales, como por ejemplo el posicionamiento GPS, el acelerómetro, la cámara, el micrófono, los altavoces o tecnologías de comunicación como el Bluetooth o el NFC.---ABSTRACT---The current world is a limitless source of information. Use and analysis of this huge amount of information is nearly impossible; but it is also difficult being able to capture and relate different kinds of data to each other and, from this analysis, draw conclusions that can lead to the fulfilment or not of a set of relevant actions. This requires the implementation of systems to facilitate the access, visualization and management of this data easier; with the purpose of being capable of relate, analyse, and allow the user to draw conclusions from them. And out of this need to manage, visualize and relate data, the Wirecloud platform was born. Wirecloud has been developed at the Computer Networks & Web Technologies Lab (CoNWeT Lab) of CETTICO group, located at Escuela Técnica Superior de Ingenieros Informáticos of Universidad Politécnica de Madrid. Wirecloud is an open-source platform that allows, using the latest web technologies, to collect the information from different sources in real time and interlinking a set of widgets and operators, make a mixture and processing of this information, so then use it and show it in the most usable way. An example of the actual use of the platform could be: using the list of deliverymen from an express delivery company in order to know, using GPS positioning from their mobile devices, which are their current locations in a map; and be able to assign them the destination and optimum route; all of this from the same display/screen. Wirecloud Mobile Project is the mobile version of the Wirecloud platform, whose main objectives aim to make Wirecloud compatible with the largest amount of mobile operative systems that are currently available, allowing its use everywhere; and enriching and improving the previously mentioned components with the native specifications and properties of the present mobile devices, such as GPS positioning, accelerometer, camera, microphone, built-in speakers, or communication technologies such as Bluetooth or NFC (Near Field Communications).

Estudio de modelos de propagación en bandas milimétricas para su futura utilización en redes de comunicaciones móviles 5G

La generalización del uso de dispositivos móviles, con su consiguiente aumento del tráfico de datos, está generando una demanda cada vez mayor de bandas de frecuencia para el despliegue de sistemas de comunicación inalámbrica, así como una creciente congestión en las bandas bajas del espectro (hasta 3 GHz). Entre las posibles soluciones a este problema, se ha propuesto que la próxima generación de sistemas celulares, 5G, hagan uso de la banda milimétrica, entre 30 GHz y 300 GHz, donde hay anchos de banda contiguos disponibles con tamaños muy difíciles de encontrar en las frecuencias en uso en la generación actual. Este Proyecto de Fin de Grado tiene como finalidad estudiar la viabilidad del despliegue de sistemas celulares en dicha banda, basándose en los estudios tanto empíricos como teóricos ya publicados, así como en las recomendaciones de la UIT donde se estudian las características de propagación en estas bandas. En un siguiente apartado, se han analizado los documentos disponibles de los distintos proyectos y grupos, como pueden ser METIS-2020, impulsado por la Comisión Europea o IMT-2020 promovido por la UIT, dedicados a definir los futuros estándares de comunicación y sus características, así como la evolución de los actuales. Aparte del trabajo de documentación, se han realizado una serie de simulaciones. En primer lugar, se ha utilizado MATLAB para estudiar el comportamiento y la atenuación de la onda electromagnética a las frecuencias de interés en diferentes ubicaciones y climas, tanto en ubicaciones habituales como extremas, estudiándose los efectos de los gases atmosféricos y los hidrometeoros. También se ha utilizado software de planificación radioeléctrica profesional para hacer estudios de cobertura en entornos tanto urbanos, entre ellos Madrid o Barcelona, suburbanos, como Tres Cantos (Madrid) y O Barco de Valdeorras (Orense), y rurales como Valdefuentes (Cáceres) y Quiruelas de Vidriales (Zamora). Por último se han recogido todos los resultados, tanto los provenientes de los estudios como los obtenidos de nuestras propias simulaciones, y se ha realizado un breve comentario, comparando estos y analizando su impacto para posibles despliegues futuros de redes 5G. ABSTRACT. The generalization of mobile device use, with its associated data traffic growth, is generating a growing demand of spectrum for its use in the deployment of wireless telecommunication systems, and a growing congestion in the lower end of the spectrum (until 3 GHz). Among the possible solutions for this problem, it has been proposed that the next generation of cellular systems, 5G, makes use of the millimeter band, between 30 GHz and 300 GHz, where there are contiguous bandwidths with sizes hardly available in the bands used in the present. This Project aims to study the feasibility of cellular system deployments in said band, based on published empirical and theoretical studies and papers, and the ITU recommendations, where the propagation characteristics in those bands are studied. In the next section, available documentation coming from the different study groups and projects like METIS 2020 promoted by the European Commission, or IMT-2020, promoted by the ITU has been studied. In the documentation, future telecommunication standards and its characteristics and the evolution of the current ones are defined. Besides the documentation work, a series of simulations have been carried out. First, MATLAB has been used to study the behavior and attenuation of the electromagnetic wave at the frequencies of interest in different locations and climates, studying the effects of atmospheric gasses and hydrometeors in conventional and extreme locations. Industry standard radioelectric planning software has been used to study the coverage in different environments, such as urban locations like Madrid and Barcelona, both in Spain, suburban locations like Tres Cantos (Madrid, Spain) and O Barco de Valdeorras (Orense, Spain) and rural locations such as Valdefuentes (Cáreces, Spain) and Quiruelas de Vidriales (Zamora, Spain). Finally, all the results, both from the documentation and our own simulations, have been collected, and a brief commentary has been made, comparing those results and their possible impact in the future deployment of 5G networks.

Towards a real-time 3D object recognition pipeline on mobile GPGPU computing platforms using low-cost RGB-D sensors

In this project, we propose the implementation of a 3D object recognition system which will be optimized to operate under demanding time constraints. The system must be robust so that objects can be recognized properly in poor light conditions and cluttered scenes with significant levels of occlusion. An important requirement must be met: the system must exhibit a reasonable performance running on a low power consumption mobile GPU computing platform (NVIDIA Jetson TK1) so that it can be integrated in mobile robotics systems, ambient intelligence or ambient assisted living applications. The acquisition system is based on the use of color and depth (RGB-D) data streams provided by low-cost 3D sensors like Microsoft Kinect or PrimeSense Carmine. The range of algorithms and applications to be implemented and integrated will be quite broad, ranging from the acquisition, outlier removal or filtering of the input data and the segmentation or characterization of regions of interest in the scene to the very object recognition and pose estimation. Furthermore, in order to validate the proposed system, we will create a 3D object dataset. It will be composed by a set of 3D models, reconstructed from common household objects, as well as a handful of test scenes in which those objects appear. The scenes will be characterized by different levels of occlusion, diverse distances from the elements to the sensor and variations on the pose of the target objects. The creation of this dataset implies the additional development of 3D data acquisition and 3D object reconstruction applications. The resulting system has many possible applications, ranging from mobile robot navigation and semantic scene labeling to human-computer interaction (HCI) systems based on visual information.

Mobile Web applications

This document presents the work that was elaborated at the company Present Technologies as part of the academic discipline Internship/Industrial Project for the Master’s degree in Informatics and Systems, Software Development branch, at Instituto Superior de Engenharia de Coimbra. The area of the mobile web applications has grown exponentially over the last few years turning it into a very dynamic field where new development platforms and frameworks are constantly emerging. Thus, the internship consisted in the study of two new mobile operating systems, Tizen and Firefox OS, as well as two frameworks for packaging of mobile web applications – Adobe PhoneGap and Appcelerator Titanium. These platforms are in the direct interest of Present Technology since it pretends to use them in its future projects in general and in the Phune Gaming project in particular. Since Television is one of the Present Technologies’ business areas, during the course of the internship it was decided to perform additionally a study of two Smart TV platforms, namely Samsung Smart TV and Opera TV, which was considered as a valuable knowledge for the company. For each of the platforms was performed a study about its architecture, supported standards and the development tools that are provided, nevertheless the focus was on the applications and for this reason a practical case study was conducted. The case studies consisted in the creation of a prototype or packaging of an application, for the case of the packaging tools, in order to prove the feasibility of the applications for the Present Technologies’ needs. The outcome of the work performed during the internship is that it raised the awareness of Present Technology of the studied platforms, providing it with prototypes and written documentation for the platforms’ successful usage in future projects.

EPiCS:engineering proprioception in computing systems

Modern compute systems continue to evolve towards increasingly complex, heterogeneous and distributed architectures. At the same time, functionality and performance are no longer the only aspects when developing applications for such systems, and additional concerns such as flexibility, power efficiency, resource usage, reliability and cost are becoming increasingly important. This does not only raise the question of how to efficiently develop applications for such systems, but also how to cope with dynamic changes in the application behaviour or the system environment. The EPiCS Project aims to address these aspects through exploring self-awareness and self-expression. Self-awareness allows systems and applications to gather and maintain information about their current state and environment, and reason about their behaviour. Self-expression enables systems to adapt their behaviour autonomously to changing conditions. Innovations in EPiCS are based on systematic integration of research in concepts and foundations, customisable hardware/software platforms and operating systems, and self-aware networking and middleware infrastructure. The developed technologies are validated in three application domains: computational finance, distributed smart cameras and interactive mobile media systems. © 2012 IEEE.

Personalized Question-Answering Mobile System

Mobile messaging is an integral and vital part of the mobile industry and contributes significantly to worldwide total mobile service revenues. In today’s competitive world, differentiation is a significant factor in the success of the business communication. SMS (Short Message Service) provides a powerful vehicle for service differentiation. What is missing, however, is the availability of personalized SMS messages. In particular, the exploitation of user profile information allows a selection and content delivery that meets preferences and interests for the individual. Personalization of mobile messages is important in today’s service-oriented society, and has proven to be crucial for the acceptance of services provided by the mobile telecommunication networks. In this paper we focus on user profile description and the mechanism for delivering the relevant information to the mobile user in accordance with his/her profile.

A Log Tool for Software Systems Analyses

The article presents a new type of logs merging tool for multiple blade telecommunication systems based on the development of a new approach. The introduction of the new logs merging tool (the Log Merger) can help engineers to build a processes behavior timeline with a flexible system of information structuring used to assess the changes in the analyzed system. This logs merging system based on the experts experience and their analytical skills generates a knowledge base which could be advantageous in further decision-making expert system development. This paper proposes and discusses the design and implementation of the Log Merger, its architecture, multi-board analysis of capability and application areas. The paper also presents possible ways of further tool improvement e.g. - to extend its functionality and cover additional system platforms. The possibility to add an analysis module for further expert system development is also considered.

Hybrid system simulation of computer control applications over communication networks

Discrete event-driven simulations of digital communication networks have been used widely. However, it is difficult to use a network simulator to simulate a hybrid system in which some objects are not discrete event-driven but are continuous time-driven. A networked control system (NCS) is such an application, in which physical process dynamics are continuous by nature. We have designed and implemented a hybrid simulation environment which effectively integrates models of continuous-time plant processes and discrete-event communication networks by extending the open source network simulator NS-2. To do this a synchronisation mechanism was developed to connect a continuous plant simulation with a discrete network simulation. Furthermore, for evaluating co-design approaches in an NCS environment, a piggybacking method was adopted to allow the control period to be adjusted during simulations. The effectiveness of the technique is demonstrated through case studies which simulate a networked control scenario in which the communication and control system properties are defined explicitly.

An investigation of consumer acceptance of M-banking

This paper aims to identify and test the key motivators and inhibitors for consumer acceptance of mobile phone banking (M-banking), particularly those that affect the consumer’s attitude towards, and intention to use, this self-service banking technology. A web-based survey was undertaken where respondents completed a questionnaire about their perceptions of M-banking’s ease of use, usefulness, cost, risk, compatibility with their lifestyle, and their need for interaction with personnel. Correlation and hierarchical multiple regression analysis, with Sobel tests, were used to determine whether these factors influenced consumers’ attitude and intention to use M-banking.
