Ensuring Mobile Device Security and Compliance at the Workplace

End users urgently request using mobile devices at their workplace. They know these devices from their private life and appreciate functionality and usability, and want to benefit from these advantages at work as well. Limitations and restrictions would not be accepted by them. On the contrary, companies are obliged to employ substantial organizational and technical measures to ensure data security and compliance when allowing to use mobile devices at the workplace. So far, only individual arrangements have been presented addressing single issues in ensuring data security and compliance. However, companies need to follow a comprehensive set of measures addressing all relevant aspects of data security and compliance in order to play it safe. Thus, in this paper at first technical architectures for using mobile devices in enterprise IT are reviewed. Thereafter a set of compliance rules is presented and, as major contribution, technical measures are explained that enable a company to integrate mobile devices into enterprise IT while still complying with these rules comprehensively. Depending on the company context, one or more of the technical architectures have to be chosen impacting the specific technical measures for compliance as elaborated in this paper. Altogether this paper, for the first time, correlates technical architectures for using mobile devices at the workplace with technical measures to assure data security and compliance according to a comprehensive set of rules.

Das Mobile Hardware-Praktikum

Im Rahmen der wissenschaftlichen Ausbildung sind Praktika vielerorts ein wichtiger Bestandteil der Lehre. Sie zeichnen sich im Regelfall dadurch aus, dass die Studierenden die gestellten Versuche an speziell ausgestatteten Laborplätzen durchführen, was neben extrem hohen Kosten zu einer Begrenzung der maximalen Teilnehmerzahl führt. In diesem Zusammenhang scheint es auf den ersten Blick nicht möglich, Konzepte einer Virtuellen Universität umzusetzen, da die Studierenden „vor Ort“ sein müssen. In diesem Dokument stellen wir das so genannte Mobile Hardware-Praktikum vor, das den Studierenden die Teilnahme zu jeder Zeit und von jedem beliebigen Ort aus erlaubt und dennoch ein Gefühl der Präsenz im Labor vermittelt. Gleichzeitig kann weit mehr als 100 Studierenden die Teilnahme ermöglicht werden. Erreicht wird dies durch ein speziell für diesen Zweck entwickeltes webbasiertes Learning Management System in Kombination mit Hardware-Komponenten, die einem voll ausgestatteten Labor-Arbeitsplatz entsprechen und den Teilnehmern für die Zeit des Praktikums auf Leihbasis zur Verfügung gestellt werden. Die Experimente werden von den teilnehmenden Gruppen in Eigenregie gelöst und elektronisch abgegeben. Die Bewertung erfolgt ebenfalls elektronisch.(DIPF/Orig.)

Novo roteiro para a Arte Nova em Aveiro e Ílhavo: proposta de uma aplicação mobile

A presente investigação tem como objeto de estudo a Arte Nova nas cidades de Aveiro e Ílhavo, traduzindo-se posteriormente na criação de uma aplicação mobile de um roteiro diferenciador referente ao património Arte Nova localizado nas duas cidades. Existe em Aveiro, uma tomada de consciência notória relativa ao património que se enquadra no espírito e nas características do estilo Arte Nova. Isso em muito se deve à originalidade e diversidade de interpretações que a caracterizam localmente. No entanto, apesar dos melhoramentos efetuados na comunicação deste património, especialmente depois da reabilitação do edifício Mário Belmonte Pessoa e da sua transformação em Museu Arte Nova, o roteiro atual não contempla todos os artefactos do estilo existentes na cidade e exclui aqueles que se encontram fora do centro urbano da cidade de Aveiro. Em Ílhavo a realidade é completamente díspar da encontrada na cidade vizinha, Aveiro, não existindo grande decoro pelo tratamento da informação referente ao estilo Arte Nova, apenas algumas referencias breves em guias culturais e um roteiro limitado no site da Câmara Municipal de Ílhavo. Paralelamente a isto, a região de Aveiro tornou-se numa das regiões com o espólio mais significativo do país. Dada à sua importância cultural e local, o roteiro diferenciador que propomos nesta investigação irá intervir de forma a melhorar o que já existe, passando pelo aprofundamento de conhecimentos sobre o tema, catalogação, cruzamento e agrupamento de toda a informação dos artefactos que se encontrem dispersos pelas duas cidades, de forma a tornar mais fácil a procura e o acesso à informação. Numa primeira fase, a investigação irá focar-se nos conteúdos afetos a cada um dos artefactos, sendo estes metodologicamente trabalhados através do método triangular de Francisco Providência, a interpretação autoral (autoria) que se traduz na evolução dos edifícios (tecnologia) e a relevância da sua história (programa) para o património nacional. Posteriormente, os conteúdos anteriormente referidos serão adaptados a uma aplicação mobile que facilitará o acesso à informação previamente selecionada referente a cada artefacto, apresentando uma breve história sobre as manifestações da Arte Nova nas cidades de Aveiro e Ílhavo. Esta aplicação mobile permitirá perceber a evolução dos edifícios desde a sua construção até à atualidade, ao nível de recuperação estrutural ou da falta de reabilitação e recuperação dos mesmos. Contribuirá para conhecer se os edifícios mantiveram (ou não) as suas características originais relativas ao desenho e tecnologia, para tal fará valerse de tecnologias como Realidade Aumentada, assim como os princípios de elaboração e leitura de QR codes, para facilitar o acesso, localização e compreensão dessa mesma informação, permitindo ainda que o seu utilizador embarque numa viagem no tempo e experiencie o roteiro de uma forma diferente. Paralelamente, pretende-se que este roteiro funcione como um roteiro único do património Arte Nova nas duas cidades, com o intuito de se expandir a outras cidades e se tornar num roteiro único do património Arte Nova na região de Aveiro. A diversidade do património Arte Nova nesta região assenta no cunho pessoal e social que os proprietários atribuíram aos seus artefactos, assim como na formação e a capacidade artística fortemente influenciada pela técnica pessoal, temperamento e sensibilidade dos seus autores, fazendo destes artefactos autênticas obras de arte, que merecem o seu estudo. Constatou-se, ao nível dos resultados que o protótipo da aplicação mobile, se adequaram ao que foi anunciado, a nível investigativo, e por isso, interessou a este estudo confirmar a demonstração do que foi enunciado. No entanto, concluiu-se que o respetivo protótipo necessita de ser ‘afinado’ em estudos futuros. Independentemente, das fragilidades encontradas, considera-se que este protótipo de aplicação mobile poderá servir como meio de excelência para a integração de conteúdos que vão mais além do que a visualização dos artefactos. Assim, contribui-se para o adensamento e acesso ao conhecimento sobre a história da Arte Nova em Portugal.

Cyber foraging for green computing, improving performance and prolonging battery life of mobile devices

The increasing dependency of everyday life on mobile devices also increases the number and complexity of computing tasks to be supported by these devices. However, the inherent requirement of mobility restricts them from being resources rich both in terms of energy (battery capacity) and other computing resources such as processing capacity, memory and other resources. This thesis looks into cyber foraging technique of offloading computing tasks. Various experiments on android mobile devices are carried out to evaluate offloading benefits in terms of sustainability advantage, prolonging battery life and augmenting the performance of mobile devices. This thesis considers two scenarios of cyber foraging namely opportunistic offloading and competitive offloading. These results show that the offloading scenarios are important for both green computing and resource augmentation of mobile devices. A significant advantage in battery life gain and performance enhancement is obtained. Moreover, cyber foraging is proved to be efficient in minimizing energy consumption per computing tasks. The work is based on scavenger cyber foraging system. In addition, the work can be used as a basis for studying cyber foraging and other similar approaches such as mobile cloud/edge computing for internet of things devices and improving the user experiences of applications by minimizing latencies through the use of potential nearby surrogates.

Kinematics and Local Motion Planning for Quasi-static Whole-body Mobile Manipulation

This thesis studies mobile robotic manipulators, where one or more robot manipulator arms are integrated with a mobile robotic base. The base could be a wheeled or tracked vehicle, or it might be a multi-limbed locomotor. As robots are increasingly deployed in complex and unstructured environments, the need for mobile manipulation increases. Mobile robotic assistants have the potential to revolutionize human lives in a large variety of settings including home, industrial and outdoor environments.

Mobile Manipulation is the use or study of such mobile robots as they interact with physical objects in their environment. As compared to fixed base manipulators, mobile manipulators can take advantage of the base mechanism’s added degrees of freedom in the task planning and execution process. But their use also poses new problems in the analysis and control of base system stability, and the planning of coordinated base and arm motions. For mobile manipulators to be successfully and efficiently used, a thorough understanding of their kinematics, stability, and capabilities is required. Moreover, because mobile manipulators typically possess a large number of actuators, new and efficient methods to coordinate their large numbers of degrees of freedom are needed to make them practically deployable. This thesis develops new kinematic and stability analyses of mobile manipulation, and new algorithms to efficiently plan their motions.

I first develop detailed and novel descriptions of the kinematics governing the operation of multi- limbed legged robots working in the presence of gravity, and whose limbs may also be simultaneously used for manipulation. The fundamental stance constraint that arises from simple assumptions about friction and the ground contact and feasible motions is derived. Thereafter, a local relationship between joint motions and motions of the robot abdomen and reaching limbs is developed. Baseeon these relationships, one can define and analyze local kinematic qualities including limberness, wrench resistance and local dexterity. While previous researchers have noted the similarity between multi- fingered grasping and quasi-static manipulation, this thesis makes explicit connections between these two problems.

The kinematic expressions form the basis for a local motion planning problem that that determines the joint motions to achieve several simultaneous objectives while maintaining stance stability in the presence of gravity. This problem is translated into a convex quadratic program entitled the balanced priority solution, whose existence and uniqueness properties are developed. This problem is related in spirit to the classical redundancy resoxlution and task-priority approaches. With some simple modifications, this local planning and optimization problem can be extended to handle a large variety of goals and constraints that arise in mobile-manipulation. This local planning problem applies readily to other mobile bases including wheeled and articulated bases. This thesis describes the use of the local planning techniques to generate global plans, as well as for use within a feedback loop. The work in this thesis is motivated in part by many practical tasks involving the Surrogate and RoboSimian robots at NASA/JPL, and a large number of examples involving the two robots, both real and simulated, are provided.

Finally, this thesis provides an analysis of simultaneous force and motion control for multi- limbed legged robots. Starting with a classical linear stiffness relationship, an analysis of this problem for multiple point contacts is described. The local velocity planning problem is extended to include generation of forces, as well as to maintain stability using force-feedback. This thesis also provides a concise, novel definition of static stability, and proves some conditions under which it is satisfied.

MobiMed: Framework for Rapid Application Development of Medical Mobile Apps

In the medical field images obtained from high definition cameras and other medical imaging systems are an integral part of medical diagnosis. The analysis of these images are usually performed by the physicians who sometimes need to spend long hours reviewing the images before they are able to come up with a diagnosis and then decide on the course of action. In this dissertation we present a framework for a computer-aided analysis of medical imagery via the use of an expert system. While this problem has been discussed before, we will consider a system based on mobile devices. Since the release of the iPhone on April 2003, the popularity of mobile devices has increased rapidly and our lives have become more reliant on them. This popularity and the ease of development of mobile applications has now made it possible to perform on these devices many of the image analyses that previously required a personal computer. All of this has opened the door to a whole new set of possibilities and freed the physicians from their reliance on their desktop machines. The approach proposed in this dissertation aims to capitalize on these new found opportunities by providing a framework for analysis of medical images that physicians can utilize from their mobile devices thus remove their reliance on desktop computers. We also provide an expert system to aid in the analysis and advice on the selection of medical procedure. Finally, we also allow for other mobile applications to be developed by providing a generic mobile application development framework that allows for access of other applications into the mobile domain. In this dissertation we outline our work leading towards development of the proposed methodology and the remaining work needed to find a solution to the problem. In order to make this difficult problem tractable, we divide the problem into three parts: the development user interface modeling language and tooling, the creation of a game development modeling language and tooling, and the development of a generic mobile application framework. In order to make this problem more manageable, we will narrow down the initial scope to the hair transplant, and glaucoma domains.

Trajectory Privacy Preservation in Mobile Wireless Sensor Networks

In recent years, there has been an enormous growth of location-aware devices, such as GPS embedded cell phones, mobile sensors and radio-frequency identification tags. The age of combining sensing, processing and communication in one device, gives rise to a vast number of applications leading to endless possibilities and a realization of mobile Wireless Sensor Network (mWSN) applications. As computing, sensing and communication become more ubiquitous, trajectory privacy becomes a critical piece of information and an important factor for commercial success. While on the move, sensor nodes continuously transmit data streams of sensed values and spatiotemporal information, known as ``trajectory information". If adversaries can intercept this information, they can monitor the trajectory path and capture the location of the source node. This research stems from the recognition that the wide applicability of mWSNs will remain elusive unless a trajectory privacy preservation mechanism is developed. The outcome seeks to lay a firm foundation in the field of trajectory privacy preservation in mWSNs against external and internal trajectory privacy attacks. First, to prevent external attacks, we particularly investigated a context-based trajectory privacy-aware routing protocol to prevent the eavesdropping attack. Traditional shortest-path oriented routing algorithms give adversaries the possibility to locate the target node in a certain area. We designed the novel privacy-aware routing phase and utilized the trajectory dissimilarity between mobile nodes to mislead adversaries about the location where the message started its journey. Second, to detect internal attacks, we developed a software-based attestation solution to detect compromised nodes. We created the dynamic attestation node chain among neighboring nodes to examine the memory checksum of suspicious nodes. The computation time for memory traversal had been improved compared to the previous work. Finally, we revisited the trust issue in trajectory privacy preservation mechanism designs. We used Bayesian game theory to model and analyze cooperative, selfish and malicious nodes' behaviors in trajectory privacy preservation activities.

Fighting child marriage in developing countries: design and development of a mobile application

Child marriage is still a great issue in developing countries and even if the interventions to prevent it are having results, they are not enough to eliminate the problem. Among the strategies that seem to work most to fight child marriage, there is the empowerment of girls with information combined with education of parents and community. As smartphones are more accessible year after year in developing countries, this thesis wants to investigate if a mobile app could be effective in fighting child marriage and which characteristics such an app should have. The research was organized in four phases and used design and creation and case study methodologies. Firstly, the literature was analyzed and an initial design was proposed. Secondly, expert interviews were performed to gain feedback on the proposed design, and afterwards prototype was built. Thirdly, a case study in the Democratic Republic of Congo (DRC) was performed to test the prototype, gaining insights and improvements through group interviews with 26 girls aged 15-19. Finally, a first version of the app was developed and a second phase of the case study was run in the DRC to understand if the girls were able to use the app. This phase included 14 girls of which 6 had participated in the prototype testing and used questionnaires as a data generation method. The app was built following the Principles for Digital Development. Even if this app is built based on the case study in DRC is modular and easily adaptable to other contexts as it is not content-specific. It was shown that is worth continuing to study this topic and it was defined a conceptual framework for designing learning apps for developing countries, in particular, to fight child, early, and forced marriage.

Integrating mobile devices into a scalable Grid Computing architecture designed to perform distributed computations

The idea of Grid Computing originated in the nineties and found its concrete applications in contexts like the SETI@home project where a lot of computers (offered by volunteers) cooperated, performing distributed computations, inside the Grid environment analyzing radio signals trying to find extraterrestrial life. The Grid was composed of traditional personal computers but, with the emergence of the first mobile devices like Personal Digital Assistants (PDAs), researchers started theorizing the inclusion of mobile devices into Grid Computing; although impressive theoretical work was done, the idea was discarded due to the limitations (mainly technological) of mobile devices available at the time. Decades have passed, and now mobile devices are extremely more performant and numerous than before, leaving a great amount of resources available on mobile devices, such as smartphones and tablets, untapped. Here we propose a solution for performing distributed computations over a Grid Computing environment that utilizes both desktop and mobile devices, exploiting the resources from day-to-day mobile users that alternatively would end up unused. The work starts with an introduction on what Grid Computing is, the evolution of mobile devices, the idea of integrating such devices into the Grid and how to convince device owners to participate in the Grid. Then, the tone becomes more technical, starting with an explanation on how Grid Computing actually works, followed by the technical challenges of integrating mobile devices into the Grid. Next, the model, which constitutes the solution offered by this study, is explained, followed by a chapter regarding the realization of a prototype that proves the feasibility of distributed computations over a Grid composed by both mobile and desktop devices. To conclude future developments and ideas to improve this project are presented.

Hábitos relacionados ao descarte pós-consumo de aparelhos e baterias de telefones celulares em uma comunidade acadêmica

Cada vez mais a sociedade contemporânea incorpora em seu cotidiano equipamentos elétricos e eletrônicos, muitos deles contendo substâncias perigosas, que representam ameaças ao meio ambiente e riscos à saúde humana. Este artigo apresenta os resultados de uma pesquisa exploratória com o objetivo de relacionar comportamento de descarte pós-consumo de aparelhos e baterias de celulares, em um grupo de consumidores de telefonia móvel, que tem proximidade em seu cotidiano de trabalho e de estudo com informações sobre saúde pública e ambiental. Os resultados da pesquisa indicam que informação pode aproximar as pessoas do problema, porém não levam por si só à produção de alterações significativas sobre o que e como fazer com o descarte pós-consumo. Os participantes do estudo possibilitaram identificar, que além da informação e acesso a coletores específicos, outros aspectos e critérios pessoais ou coletivos interferem no procedimento de descarte: percepção sobre risco, valor econômico disponibilizado na compra do aparelho e vínculos afetivos, entre outros. Esses fatores podem produzir diferentes respostas dos usuários sobre como lidar com as inovações tecnológicas de uso pessoal.
