The Android Operating System is a complete platform for mobile devices principally for Smartphones developed by Google in 2008. It is gaining an increasingly global market space, due to its open-source code. Attacks on mobile phones are not a current practice. The first virtual virus called Cabir, was developed in 2004, and it is concerned only the Symbian operating system. Studies show great evolution of digital attacks to the Android operating system. Honeypots (tools that have many features such as deceive the attacker) can be quite useful in the context of network security. They make the attacker think that he is actually interacting with an operating system, but in fact the attacker is being monitored. Therefore, the present thesis is aimed to develop a Framework (framework) to generate a virtual Honeypot at the level of application for the Android operating system. The methodological procedures for the preparation of this work are the: bibliography research articles, essays and literature specific.. In this work, we show that the attacker can be monitored in mobile devices through a Honeypot generated by the framework developed here in order to be used as a tool in network security based on deception. From our experience in this study, we report some essential recommendations points for improving and expanding this work. / Os dispositivos móveis, como os Smartphones, tornaram-se indispensáveis nos dias atuais, devido ao aumento do poder de processamento, maior espaço de armazenamento de dados, baterias com maior autonomia de tempo, conexão a rede wireless e à rede 3g. O Sistema Operacional Android é uma plataforma completa para dispositivos móveis principalmente para aparelhos celulares inteligentes, desenvolvida pela Google em 2008. Ganhando nesse contexto cada vez mais espaço no mercado mundial, devido ser open-source, ou seja, código fonte aberto. Ataques a telefones celulares não é uma prática atual, o primeiro vírus virtual denominado de Cabir, foi desenvolvido em 2004, e visava exclusivamente o sistema operacional Symbiam. Estudos apresentam grande evolução de ataques digitais ao sistema operacional Android. Os Honeypots (ferramentas que dispõem de diversas funcionalidades e que tem como objetivo principal enganar o invasor) podem ser bastante úteis no âmbito de segurança de rede. Eles fazem com que o atacante pense que está interagindo de fato com um sistema operacional, mas na verdade o atacante está sendo monitorado. Neste sentido, o presente trabalho foi realizado com o objetivo de desenvolver um Framework (arcabouço) para gerar Honeypot virtual a nível de aplicação para o sistema operacional Android. Os procedimentos metodológicos para elaboração deste trabalho foram: pesquisa bibliográfica (artigos, dissertações e literaturas especificas). Conclui-se que é possível monitorar o atacante de dispositivos móveis através do Honeypot gerado pelo Framework desenvolvido, de forma a ser usado como uma ferramenta em segurança de redes baseados em iludir. Diante da experiência vivenciada neste estudo, expomos algumas recomendações, pontos imprescindíveis para melhorias do tema abordado, como: mais visibilidade ao Honeypot e ampliação para outros sistemas operacionais móveis.

Pesquisas sobre inovação e o mercado de baixa renda focam eminentemente no desenvolvimento de produtos e gestão de marketing, assumindo uma postura top-down, das empresas para os consumidores. Esta postura sugere textos prescritivos sobre gestão de empresas multinacionais, tanto em mercados desenvolvidos quanto em mercados emergentes. Do ponto de vista individual, tem se dada pouca atenção para compreender a adoção da inovação pelos consumidores de baixa renda. A presente tese busca investigar o conceito de inovação por esta perspectiva, assumindo uma postura bottom-up, focando principalmente nos consumidores. Desta forma, o objetivo da tese consiste em analisar os fatores que influenciam a adoção da inovação de produtos por consumidores de baixa renda. O recorte empírico da tese consiste no mercado de smartphones que é um produto com atributos inovadores e acessíveis aos consumidores de baixa renda. Os pressupostos teóricos que embasam a tese consistem nas restrições encontradas pelos consumidores do mercado da base da pirâmide, que englobam a baixa renda, falta de informação e conhecimento e falta de confiança. Essas restrições individuais causadas por problemas estruturais (transporte, educação, saúde, moradia, saneamento e etc.) afetam negativamente a adoção de inovação por consumidores. Essa relação sustenta o efeito principal do modelo da tese que consiste na hipótese 1. A literatura e conceitos utilizados para subsidiar a pesquisa foram Antecedentes do UTAUT 2, 4 As de Anderson e Billou, 12 Princípios de Prahalad, Inovação Disruptiva, Inovação Reversa e Inovação Inclusiva. A revisão destas teorias resultou em quatro conceitos que consideramos fatores influenciadores da adoção da inovação no mercado de baixa renda, que são as Características e Benefícios, Facilidade de Uso, Simplicidade e Preço Acessível dos produtos. Esses conceitos resultantes da revisão da literatura sustentaram as hipóteses 2, 3, 4 e 5 que analisam o efeito moderador dessas variáveis sobre a adoção da inovação. Para atingir cada um dos dois objetivos específicos da tese, dois estudos foram realizados. O estudo 1, fase exploratória, consistiu em seis grupos de foco realizados na Favela de Paraisópolis em São Paulo e uma pesquisa complementar com 11 entrevistas realizadas em regiões rurais do Sul da Índia. O estudo 1 objetivou identificar os fatores que influenciam a adoção da inovação por consumidores de baixa renda. O estudo 2, fase descritiva, consistiu em uma pesquisa de levantamento realizada em 3 regiões de baixa renda na cidade de São Paulo que objetivou analisar a relação direta entre as restrições dos consumidores de baixa renda e a adoção da inovação (H1) e o efeito moderador de Características e Benefícios (H2), Facilidade de Uso (H3), Simplicidade (H4) e Preço Acessível (H5) desta relação. O estudo 2 também contemplou uma pesquisa complementar de levantamento, realizada com consumidores de alta renda. Os principais resultados do estudo 1 (fase exploratória) revelam que as restrições de renda, informação, conhecimento e confiança afetam a taxa de adoção da inovação. Além disso, mais do que o aquisição e compra dos produtos, a adoção está diretamente relacionada ao uso dos smartphones. Por fim, identificamos que há uma sobreposição de agentes no mercado de smartphones que gera confusão para os consumidores. Diferentes empresas fabricantes, varejistas, operadoras e desenvolvedoras dos sistemas operacionais se posicionam no mercado concomitantemente e acabam confundindo os consumidores acerca da real responsabilidade e atividade de cada um deles. Os principais resultados do estudo 2 (fase descritiva) confirmam as hipóteses 1 (efeito principal), 3, 4 e 5 (efeito moderador de FU, SI e PA), indicando estatisticamente que as restrições da baixa renda afetam negativamente a adoção da inovação e que a facilidade de uso, simplicidade e preço acessível moderam positivamente essa relação. / Research on innovation and the low-income market usually focus on product development and marketing management, taking a top-down approach, from companies to consumers. This approach suggests prescriptive texts on management of multinational companies in both developed markets and emerging markets. From an individual point of view, it has given little attention to understanding the adoption of innovation by low-income consumers. This PhD dissertation aimed to investigate the concept of innovation from this perspective, taking a bottom-up approach, mainly focusing on consumers rather than companies. Therefore, the aim of the dissertation is to analyze the factors influencing the innovation adoption of products for low-income consumers. The empirical object of the dissertation consists in the smartphone market since is a product with innovative features and affordable to low-income consumers. The theoretical assumptions that support the dissertation consists of the constraints faced by consumers in the market of the base of the pyramid, which include low income, lack of information and knowledge and lack of confidence. These individual constraints caused by infrastructural problems affect negatively the adoption of innovation by consumers. This relationship supports the main effect of the dissertation model, the hypothesis 1. The literature and concepts used to support the research were the Antecedents of UTAUT 2, 4A\'s of Anderson and Billou, 12 Principles of Prahalad, Disruptive Innovation, Innovation Reverse, and Inclusive innovation. A review of these theories resulted in four concepts that we consider factors that influence adoption of innovation in low-income market, which are the Features and Benefits (CB), Ease of Use (FU), Simplicity (SI), and Affordability (PA) of products. These concepts resulting from the literature review supported the hypotheses 2, 3, 4 and 5 that analyze the moderating effect of these variables on the adoption of innovation. To achieve each of the two specific objectives of the dissertation, two studies were conducted. Study 1, exploratory phase, consisted of six focus groups conducted in Favela of Paraisópolis in Sao Paulo and a complementary inquiry of 11 in-depth interviews conducted in rural areas of South India. The study 1 aimed to identify the factors that influence adoption of innovation by low-income consumers. Study 2, descriptive phase, consisted of a survey carried out in three low-income areas in São Paulo city that aimed to analyze the direct relationship between the constraints of low-income consumers and the adoption of innovation (H1) and moderating effect of Features and Benefits (H2), Ease of Use (H3) Simplicity (H4) and Affordable Price (H5) of this relationship. Study 2 also included an additional research involving a survey carried out with high-income consumers. The main results of the study 1 (exploratory phase) show that the income constraints, lack of information, knowledge and confidence really affect the rate of adoption of innovation. In addition, more than the acquisition and purchase of products, adoption is directly related to the use of smartphones. Finally, we identified that there is an overlap of agents in the smartphone market that creates confusion for consumers. Different manufacturers, retailers, operators and developers of systems are positioned in the market concurrently and end up confusing consumers about the real responsibility and activity of each of them. The main results of the study 2 (descriptive phase) confirm the hypotheses 1 (main effect), 3, 4 and 5 (moderating effect of FU, SI, and PA), indicating statistically that the restrictions on low-income negatively affect the adoption of innovation and the ease of use, simplicity and affordability positively moderate this relationship.

Rapporten handlar om olika metoder för att lokalisera smartphones och skapandet av en Androidapplikation. Applikationen skulle visualisera Campusområdet vid Örebro universitet för att öka medvetenheten och säkerhetskänslan för personer som är där kvällar och nätter. Implementationen av systemet beskrivs tillsammans med de problem som uppstod, samt dess lösningar. / The report is about different methods of localizing smartphones and the creation of an Android application. The application should visualize the Campus for Örebro university to raise awareness and the sense of security for people who are there at night. The implementation of the system is described along with the problems during development, and how they were solved.

iProspect is a global digital marketing agency and work primarily with search marketing. They were the first search engine marketing agency in the world when the company started up 1996 in Boston, Massachusetts, and the first in Sweden to offer services in search marketing after establishing themselves on the Swedish market the following year. iProspect can be found in the södermalm office in south central Stockholm. They are a comprehensive agency within search and offer everything from search engine optimization and sponsored links to advertising on social media. They’re goal is to lead developments in search marketing and to keep ahead of competition. To do this they must constantly challenge themselves. The market is constantly evolving and new services are offered regularly. This report describes the development of a design document for a mobile application for increased knowledge and for sharing knowledge about a new service from iProspect . The service in question, attribution, is already sold today by iProspect in markets abroad and the ambition is to do so also in Sweden as soon as there are resources in the form of "know-how". The draft design document should evolve to include their employees with increased knowledge of how attribution can be applied as a service. During the execution of this work, interviews, usability tests with prototypes and observations were made and conducted. Based on the methodology and the work process, the results have been analyzed and discussed. Hopefully the application will be of use prior the implementation process of the new service.

Smartphones have become more common as business tools within the workplace. With its many features and great flexibility, the smartphone has stormed the business world and become an alternative or complement to the laptop. As these mobile units' popularity has increased, the interest of businesses to invest in this new technology has increased, but has security kept up with the technology developments? This study aims to conduct a study to see if the companies in the IT industry have the same safety awareness for smart phones to laptops. The study shows that companies have greater safety awareness and higher safety requirements for laptops than smartphones. Meanwhile, both end-users and management are well aware of the risks and threats that the smartphone is facing.

Smarttelefoner har blivit vanligare som affärsverktyg inom arbetslivet. Med sina många funktioner och stora flexibilitet har smarttelefonen stormat affärsvärlden och kommit att bli ett alternativ eller komplement till den bärbara datorn. Allt eftersom smarttelefoners popularitet har ökat, har även företagens intresse att investera i denna nya teknik vuxit, men har säkerheten följt med i denna snabba utveckling? Denna studies syfte är att genomföra en undersökning för att se ifall företag inom IT-branschen har samma säkerhetsmedvetande för smarttelefoner som för bärbara datorer.   Studien visar att företag har ett större säkerhetsmedvetande och högre säkerhetskrav för bärbara datorer än smarttelefoner. Samtidigt är både slutanvändarna och företagsledningen väl medvetna om de risker och hot som smarttelefonen ställs inför. / Smartphones have become more common as business tools within the workplace.

Syftet med denna undersökning är att med hjälp av två vetenskapliga metoder, kvalitativa intervjuer och användardagböcker ta reda på hur användares mobila brukarvanor ser ut och vilka typer av tjänster kan de ligga till grund för baserat på ett Smart city-perspektiv. Arbetet kommer även att analysera och utveckla metodiken för fortsatta studier inom ämnet. Mobilen har under de senaste åren utvecklats till att bli en enhet där dess ursprungliga telefonfunktioner blivit sekundära egenskaper. Dess främsta ändamål är fortfarande för att kommunicera med andra, men i första hand genom andra typer av tjänster. Man kan idag även se hur utvecklingen går från ett bruk av digitala tjänster där varje enhet har specifika syften, till ett bruk där enheter samarbetar och delar ett gemensamt syfte. I och med att vårt bruk, och våra vanor, av dessa enheter förändras, så förändras även naturen hos tjänsterna de tillhandahåller. Man kan se en utveckling mot, och en efterfrågan för, tjänster som genom att utnyttja ny teknologi kan beskrivas bryta gränsen mellan det digitala och den fysiska verkligheten. Vilket ur ett Smart City-perspektiv kan ha stor potential inom flera områden av samhälls- och verksamhetsutveckling. Det går även att se att synen på hur vi konsumerar digitala tjänster förändras. Från att ha haft en väldigt enhetsfokuserad syn, där varje enhet har specifika ändamål, går vi mot ett bruk av tjänster där enheten i sig inte är viktig. Många tjänster finns idag på flera enheter, och enheterna fungerar mer som ett samarbetande ekosystem än enskilda enheter med egna syften. Enheterna delar snarare ett gemensamt syfte, att agera fönster mot internet. / The purpose of this study is to find out how mobile user habits can provide a basis for applications and services based on a Smart City perspective, this by using two scientific methods, interviews and user diaries. The study will also analyze and develop the method for further studies in this subject. The cell phone has in recent years evolved into a unit where the original phone functions and features have become secondary. Even though its main purpose is still to communicate with others, it’s now done primarily through other types of services. Today the development goes from a use of digital services where each unit has a specific purpose, to a practise where they work together and share a common purpose. As a result of the fact that our use and our habits of these devices are changing, the nature of the services provided by these devices are also changing. Due to this, there is an ongoing evolution towards, and a demand for, new services that can take advantage of new technologies to dissolve the border between the digital and the physical reality. Which, from a Smart City perspective, could have great potential in several areas of social and organizational development. One can also se that the way we consume digital services is changing. We have gone from having a device centerd focus, were every unit has a specific purpose to a serviced centerd focus, were the units work as a collaborative ecosystem. These units share a collective pupose, to act as a window towards the internet.

Cette thèse étudie la productivité du consommateur dans le cadre de son magasinage sous l’influence de la technologie mobile. Dans un premier temps, une revue de littérature pluridisciplinaire a mis en exergue la polysémie du concept de productivité et les particularités de la définition de la productivité dans le secteur tertiaire. Une analyse comparative des travaux sur la productivité du consommateur a par la suite permis de pointer la diversité des définitions et des méthodes de mesure de ce concept et de justifier la pertinence de revisiter ce concept au niveau d’une expérience de magasinage dans le contexte digitalisé en prenant en compte les caractéristiques des technologies mobiles. À cet effet, une étude qualitative à partir de 31 entretiens semi-directifs a été réalisée. L’analyse des verbatim assistée du logiciel NVivo a débouché sur une conceptualisation élargie de la productivité du consommateur, comprenant l’efficience temporelle, l’efficience monétaire, et l’efficacité. Les résultats des entretiens et de la revue de littérature ont servi à construire un modèle conceptuel de productivité du consommateur sous l’influence du smartphone, explicitant les antécédents des dimensions de la productivité du consommateur et leurs effets sur la satisfaction. Enfin, un échantillon de 300 individus a permis de tester ce modèle par équations structurelles dans le cadre de magasinage vestimentaire. Les données ont été analysées et modélisées par équations structurelles à l’aide du logiciel Smart PLS. Les résultats de l’étude quantitative attestent d’un effet positif significatif des dimensions de la productivité du consommateur sur la satisfaction. Les relations entre l’efficacité et l’efficience temporelle, d’une part, et la satisfaction, d’autre part, sont modérées par la fréquence d’utilisation du smartphone pour le magasinage vestimentaire. Les résultats ont également permis d’identifier les antécédents des dimensions de la productivité du consommateur : la polychronicité, la conscience temporelle, la conscience de prix, l’implication, l’attitude envers les technologies mobiles et le choix des canaux marketing dans le parcours d’achat. Au vu des résultats des deux études, nous discutons la pertinence pour les distributeurs d’adopter la démarche de management de productivité du consommateur appuyée sur les possibilités offertes par la technologie mobile. / This PhD dissertation explores consumer shopping productivity under the influence of mobile technology. First, a multidisciplinary review of productivity literature emphasized the polysemy of productivity concept and some specific features of its definition in service industry. A comparative analysis of consumer productivity literature highlights the diversity of approaches to the analysis of consumer productivity and of its measures, and the relevance to revisit this concept in the digital world, taking into account the specific features of mobile technology.To do so, we realized a qualitative study by 31 semi-structured interviews. The verbatim analysis by means of NVivo software resulted in an extended conceptualization of consumer productivity, including temporal efficiency, monetary efficiency, and efficacy. Based on the literature review and the qualitative study results, we proposed a conceptual model of consumer productivity under the influence of mobile technologies, presenting the antecedents of consumer productivity dimensions and their impact on consumer satisfaction.Finally, a sample of 300 individuals was used to test this model in the context of apparel shopping. The data were analyzed by the structural equations modelling partial least squares with Smart PLS software. The results of the quantitative study confirm the positive impact of consumer productivity on satisfaction. The relations between efficacy and temporal efficiency were moderated by the frequency of the use of smartphone in apparel shopping. The results allowed us to identify the antecedents of consumer productivity: polychronic orientation, time consciousness, price consciousness, implication, attitude towards mobile technologies, and the choice of marketing channels in shopping trips. In the light of the results of the two studies, we argue for the relevance of consumer productivity management approach for retailers exploiting the vast opportunities offered by mobile technologies.

Mit der Verbreitung des Web begann auch die Entwicklung web-basierter Fragebogen, die es Wissenschaftlern ermöglichen, auf effiziente Weise große Datenmengen zu erheben. Da zunehmend Smartphones für Online-Anwendungen genutzt werden, bietet es sich an, Personen für die Teilnahme an webbasierten Studien über mobile Geräte zu erreichen. Doch wie sind diese Studien speziell für Smartphones zu gestalten? [... aus der Einleitung]

„Hast Du Schwierigkeiten, die richtige Ansprache für Millennials zu finden?“ Dann empfiehlt die Onlinemarketingplattform www.onlinemarketing.de sich die perfekte Videowerbung für die Generation Y anzusehen. Im Video sind „hippe, junge Menschen in Zeitlupe“ zu sehen, die fröhlich sind, sich frei fühlen, lachen, bunte Haare haben, gern mit Freunden zusammen sind und Spaß an der Konversation haben, fotografieren, posten, liken und teilen. Natürlich werden im Video die Klischees überzogen und auch aufs Korn genommen. Aber die Kernaussage stimmt mit der Definition der Millennials überein: Sie sind technikaffin, legen Wert auf ihre Selbstverwirklichung und verfolgen eine hohe Leistungsorientierung. Sie studieren und investieren in die Ausbildung. Es ist aber auch die Generation, die mit dem Smartphone groß geworden ist. Sie beziehen nahezu alle Informationen aus dem Internet und halten sich täglich über mehrere Stunden in den sozialen Medien auf. Die Autorin setzt sich in ihrer Dissertation mit dem Thema auseinander, wie diese Generation sich Wissen aneignet. Sie möchte in Experimenten nachweisen, dass die Millennials anders lernen, weil sie aus der Informationsflut selektieren müssen. Sie wollen ihr Wissen möglichst effektiv, auf das Wesentliche reduziert, präsentiert bekommen. Das sind Erfahrungen der Autorin aus der Lehre. Dieses Paper fasst Hypothesen und Gedanken zusammen, die provokant und als mögliches Zukunftsszenario beschrieben werden. Dabei geht es einerseits um die Distribution. Wo müssen Lehrvideos veröffentlicht werden, dass sie von der lernenden Zielgruppe wahrgenommen und angenommen werden. Auf der anderen Seite geht es auch um den Content selbst und wie er dargestellt wird – strukturell und visuell. Die Autorin zieht dafür Parallelen zum Journalismus sowie zum Marketing.
