Purpose: Firstly, to investigate if the decline of trust in traditional financial transaction providers, namely banks, has resulted in an increase of trust in Alternate Financial Transaction Providers (AFTP). Secondly, to identify antecedents to building trust in AFTP held by Swedish Millennials. Methodology: Qualitative research consisting of focus groups were used to collect primary data. A total of three focus group were held, excluding a trial session. Participants in the focus groups were Swedes between 22 and 30 years of age (Swedish Millennials). Findings: That trust in banks amongst Swedish Millennials is decreasing. Concurrently, there is a general willingness of Swedish Millennials to trust AFTP given the presence of certain antecedents (human, technological and organisational).

This thesis explores the impact of securities transaction tax (STT) on stock market quality. In order to identify the effects of STT on trading activity and market quality two recent STT introductions in France and Italy are analyzed. The effects are observed on panel data in four periods utilizing several trading activity and market quality measures. Following previous literature difference-in-differences approach is applied using various control groups including German and Spanish equities. The results point to significant decrease in trading activity and increase in bid-ask spreads in France following STT imposition. The impact on volatility is statistically insignificant across different specifications and estimation periods. The results for Italy are inconclusive due to possible contamination by political events, but the evidence indicates decrease in trading activity following STT introduction.

In recent times the usage of smart phones has significantly increased. Businesses are transforming to make more out of smart phones. As a consequence, there is an increasing demand to have more and more mobile applications. Among other areas, mobile applications are also being used to make financial transactions. Applications used for financial transactions need to be more reliable and have end-to-end security. To implement security we heavily depend on cryptography and the heart of cryptography is the keys which are used in cryptographic processes (encryption/decryption). Therefore, it is essential not only to protect, but also to properly manage these keys, so that a robust and secure system can be achieved. This research work provides a complete implementation of symmetric key management for mobile phone applications with a focus on financial data using a key hierarchy approach. We have developed a key management system which allows smart phones to download the cryptographic key hierarchy. This key hierarchy is used to encrypt and decrypt financial data, such as PIN and other transaction information. Using this application (key management system), we can achieve an end-to-end security between client (mobile phones) and payment server (banking server). This research work presents implementation of key management system for Android OS only.

Um dos objetivos mais importantes de qualquer sistema de detecção de fraudes, independente de seu domínio de operação, é detectar o maior número de fraudes com menor número de alarmes falsos, também denominados de falsos positivos. A existência de falsos positivos é um fato inerente a qualquer sistema de detecção fraudes. O primeiro passo para alcançar esse objetivo é identificar os atributos que podem ser usados para diferenciar atividades legítimas das fraudulentas. O próximo passo consiste em identificar um método para cada atributo escolhido para efetuar essa distinção. A escolha adequada dos atributos e dos métodos correspondentes determina em grande parte o desempenho de um detector de fraudes tanto em termos da relação entre o número de fraudes detectadas e o número de falsos positivos, quanto em termos de tempo de processamento. O desafio desta escolha é maior ao se tratar de um detector de fraudes em tempo real, isto é, fazer a detecção antes que a fraude seja concretizada. O objetivo deste trabalho é apresentar a proposta de uma arquitetura de um sistema de detecção de fraudes em tempo real em transações bancárias via Internet, baseando-se em observações do comportamento local e global de usuários. O método estatístico baseado em análise diferencial é usado para obter a evidência local de uma fraude. Neste caso, a evidência de fraude é baseada na diferença entre os perfis de comportamento atual e histórico do usuário. A evidência local de fraude é fortalecida ou enfraquecida pelo comportamento global do usuário. Neste caso, a evidência de fraude é baseada no número de acessos efetuados em contas diferentes feitos pelo dispositivo utilizado pelo usuário, e por um valor probabilístico que varia com o tempo. A teoria matemática de evidências de Dempster-Shafer é utilizada para combinar estas evidências e obter um escore final. Este escore é então comparado com um limiar para disparar um alarme indicando a fraude. A principal inovação e contribuição deste trabalho estão na definição e exploração dos métodos de detecção baseados em atributos globais que são de natureza específica do domínio de transações financeiras. Os resultados da avaliação utilizando uma base de dados com registros de transações correspondentes a perfis reais de uso demonstraram que a integração de um detector baseado em atributos globais fez aumentar a capacidade do sistema de detectar fraudes em 20%. / One of the most important goals of any fraud detection system, whichever is the domain where it characterizes the possibility for fraud, is to detect the largest number of frauds with fewer false alarms, also denominated false positives. The existence of false positives is a fact inherent to any fraud detection system. The first step in achieving this goal is to identify the attributes that can be used to differentiate between legitimate and fraudulent activities. The next step is to identify a method for each attribute chosen to make this distinction. The proper choice of the attributes and corresponding methods largely determines the performance of a fraud detector, not only in terms of the rate between the number of detected frauds and the number of false positives, but in terms of processing time. The challenge of this choice is higher when dealing with fraud detection in real time, that is, making the detection before the fraud is carried out. The aim of this work is to present the proposal of an architecture of a real time fraud detection system for Internet banking transactions, based on local and global observations of users behavior. The statistical method based on differential analysis is used to obtain the local evidence of fraud. In this case, the evidence of fraud is based on the difference between the current and historical behavior of the user. The frauds local evidence is strengthened or weakened by the users global behavior. In this case, the evidence of fraud is based on the number of accesses performed on different accounts made by the device used by the user and by a probability value that varies over time. The Dempster-Shafers mathematical theory of evidence is applied in order to combine these evidences for final suspicion score of fraud. This score is then compared with a threshold to trigger an alarm indicating the fraud. The main innovation and contribution of this work are the definition and exploration of detection methods based on global attributes which are domain specific of financial transactions. The evaluation results using a database with records of transactions corresponding to actual usage profiles showed that the integration of a detector based on global attributes improves the system capacity to detect frauds in 20%.

La thèse propose une esquisse des enjeux juridiques de l'adoption d'une taxe sur les transactions financières par le biais de la coopération renforcée en Europe. Les recherches portent plus précisément sur la technicité fiscale de la conception de cette imposition levée sur les transactions financières et les défis juridiques qui dérivent de son adoption par le biais de la coopération renforcée. La taxe, telle que conçue ne présente pas d'éléments de nature à la rendre contraire au droit international et européen et dans quelle mesure le cadre institutionnel qui l'accueille, celui de la coopération renforcée, est susceptible de remédier à ces possibles obstacles. La taxe sur les transactions financières telle que conçue par Tobin est destinée à s'appliquer par une communauté ample de juridictions fiscales. Son adoption à l'échelle régionale pose des problèmes juridiques qui tiennent à deux chefs. D'une part, l'imposition d'un secteur mobile et internationalisé dans son activité est confrontée à la planification fiscale d'évitement de l'impôt, facteur fragilisant les attendes sur son potentiel fiscal. D'autre part, l'extraterritorialité de l'imposition, qualité inhérente aux contours conceptuels de la taxe produit des effets dont la justification, tant en droit international et européen, primaire que dérivé, n'est pas aisément obtenue. Les difficultés découlant de la technicité fiscale de l'imposition ne s'épuisent pas dans les arguments précités. Elles demeurent intimement liées à l'élaboration d'une politique fiscale européenne de répartition de ressources fiscales entre États membres. / This thesis stems from European Taxation and it aims at providing for a legal appraisal of the contemplated introduction of a EU Financial Transaction Tax (FIT). The thesis, divided in three parts, is dedicated to the 2013 FIT Proposal, tabled in by the Commission and gaining support among some EU Member States, which wish to proceed by Enhanced Cooperation in this area. Part I of the thesis sets up the stage, focuses on interpreting the draft Proposal, and seeks for the "missing links": those unresolved issues, raised by tax academics, for making the tax legally consistent and coherent. Modelling an efficient and fair financial transaction tax is a delicate affair for tax experts. Within this appraisal, inconsistencies and incoherence, in the actual wording of the Proposal, have been overviewed. Part II focuses on the alleged infringement of international law, primary and secondary from FTT's implementation. Beyond the academic interest, by delving into that area of law, the conclusions drawn may be ground for further reflexion in regard of tax payers' protection. In the chapters that follow, we scrutinize the general institutional conditions granting competence to the EU for harmonising indirect taxes and we survey the requirements to be met in the specific legal frame of the Enhanced cooperation. More, we shed some light on the FTT's shape under the 2013 Proposal in regard of the European Treaties and secondary law.

In February 2013, eleven Member States agreed to adopt the Commissions' Proposal for a Council Directive implementing enhanced cooperation in the area of financial transaction tax, COM (2013)71 final. This article reviews three thematic areas frequently discussed by practitioners and academia alike on the impact that the Proposal could have on companies operating within participating Member States. This includes the impact on capital and related costs, business strategy and compliance considerations. I ask the question whether the unintentional repercussions could be mitigated by making adjustments to the current Proposal including the expansion of exemptions and the adoption of an implementation framework that takes inspiration from the Value Added Tax System that is already implemented across Member States.

The diploma thesis deals with the taxation of financial institutions focused on European Union. The thesis provides a short view on the inception of financial crisis in USA and the costs spent by national governments on rescue of systemic important institutions on the market. The history of banking tax concept is briefly summarized on theoretical level and also two real historical examples of taxation in financial sector are provided. The main part of the work is focused on the current proposal of European Commission and the impact of its implementation. The practical part of diploma thesis is based on particular model examples how this proposal would work in practice.

Banking crisis and following sovereign debt crisis are the cause of some changes on the financial market. This thesis is mainly focused on the debt crisis and its impact on financial sector stability. Roots, consequences and probable solutions of the debt crisis are also examined. Among analysed solutions were included proposals for financial transaction tax, stability bonds and regulation under new concept of CRD IV, bail-in and federalization of the eurozone. Analysed are also ratings, fiscal policy and optimality of the euro currency areas and its impact on stability of financial institutions. According to results, some proposals could be contrary to each other if implemented in its present form. Or it can increase moral hazard of financial institutions. Another consequence is establishment of new regulations. On the other hand, positive is that financial institutions have endured the sovereign debt crisis.
