...coisas inexplicáveis e pessoas incomparáveis" como vocês! Obrigado por tudo, Filipe Abstract The Retail Banking Industry has been severely affected by fraud over the past few years. Indeed, despite all the research and systems available, fraudsters have been able to outsmart and deceive the banks and their customers. With this in mind, we intend to introduce a novel and multi-purpose technology known as Stream Computing, as the basis for a Fraud Detection solution. Indeed, we believe that this architecture will stimulate research, and more importantly organizations, to invest in Analytics and Statistical Fraud-Scoring to be used in conjunction with the already in-place preventive techniques. Therefore, in this research we explore different strategies to build a Streambased Fraud Detection solution, using advanced Data Mining Algorithms and Statistical Analysis, and show how they lead to increased accuracy in the detection of fraud by at least 78% in our reference dataset. We also discuss how a combination of these strategies can be embedded in a Stream-based application to detect fraud in real-time. From this perspective, our experiments lead to an average processing time of 111,702ms per transaction, while strategies to further improve the performance are discussed.

...4. 4.1 Big Data Introduction In 2004, Wal-Mart claimed to have the largest data warehouse with 500 terabytes storage (equivalent to 50 printed collections of the US Library of Congress). In 2009, eBay storage amounted to eight petabytes (think of 104 years of HD-TV video). Two years later, the Yahoo warehouse totalled 170 petabytes1 (8.5 times of all hard disk drives created in 1995)2. Since the rise of digitisation, enterprises from various verticals have amassed burgeoning amounts of digital data, capturing trillions of bytes of information about their customers, suppliers and operations. Data volume is also growing exponentially due to the explosion of machine-generated data (data records, web-log files, sensor data) and from growing human engagement within the social networks. The growth of data will never stop. According to the 2011 IDC Digital Universe Study, 130 exabytes of data were created and stored in 2005. The amount grew to 1,227 exabytes in 2010 and is projected to grow at 45.2% to 7,910 exabytes in 2015.3 The growth of data constitutes the “Big Data” phenomenon – a technological phenomenon brought about by the rapid rate of data growth and parallel advancements in technology that have given rise to an ecosystem of software and hardware products that are enabling users to analyse this data to produce new and more granular levels of insight.

...McKinsey Global Institute June 2011 Big data: The next frontier for innovation, competition, and productivity The McKinsey Global Institute The McKinsey Global Institute (MGI), established in 1990, is McKinsey & Company’s business and economics research arm. MGI’s mission is to help leaders in the commercial, public, and social sectors develop a deeper understanding of the evolution of the global economy and to provide a fact base that contributes to decision making on critical management and policy issues. MGI research combines two disciplines: economics and management. Economists often have limited access to the practical problems facing senior managers, while senior managers often lack the time and incentive to look beyond their own industry to the larger issues of the global economy. By integrating these perspectives, MGI is able to gain insights into the microeconomic underpinnings of the long-term macroeconomic trends affecting business strategy and policy making. For nearly two decades, MGI has utilized this “micro-to-macro” approach in research covering more than 20 countries and 30 industry sectors. MGI’s current research agenda focuses on three broad areas: productivity, competitiveness, and growth; the evolution of global financial markets; and the economic impact of technology. Recent research has examined a program of reform to bolster growth and renewal in Europe and the United States through accelerated productivity growth; Africa’s economic potential;...

...CHAPTER 3 CO M P U TE R A N D I NT E R N E T C R IME QUOTE In view of all the deadly computer viruses that have been spreading lately, Weekend Update would like to remind you: when you link up to another computer, you’re linking up to every computer that that computer has ever linked up to. —Dennis Miller, Saturday Night Live, U.S. television show VIGNETTE Treatment of Sasser Worm Author Sends Wrong Message Unleashed in April 2004, the Sasser worm hit IT systems around the world hard and fast. Unlike most computer viruses before it, the Sasser worm didn’t spread through e-mail, but moved undetected across the Internet from computer to computer. It exploited a weakness in Microsoft Windows XP and Windows 2000 operating systems. By the first weekend in May, American Express, the Associated Press, the British Coast Guard, universities, and hospitals reported that the Sasser worm had swamped their systems. Computer troubles led Delta Airlines to cancel 40 flights and delay many others. Microsoft quickly posted a $250,000 reward, and by mid-May, authorities apprehended Sven Jaschen, a German teenager. Jaschen confessed and was convicted after a three-day trial. Jaschen could have received up to five years in prison, but because he was tried as a minor, the court suspended his 21-month sentence, leaving him with only 30 hours of community service.

...in Banking Insight and Foresight Institute for Development and Research in Banking Technology (Established by Reserve Bank of India) Foreword The Indian banking industry, almost in keeping with the deep entrepreneurial approach of the country s business, has come a long way. This report is an effort to capture some exemplary initiatives and developments so far as well as discuss the emerging trends. The insights and understanding of the technology trends and ground-level work being done by the banks has been culled from the nominations received from banks for the IDRBT Banking Technology Excellence Awards 2010. The transformation of Indian banks in the last decade has been phenomenal from local branch banking to global presence and anywhere-anytime banking. Most of the regular banking transactions can today be carried out from mobile phones. Sustained reforms and information technology (IT) have played a pivotal role since the initiation of the second phase of reforms post 1998. The benefits of technology such as scale, speed and low error rate are also reflecting in the performance, productivity and profitability of banks, which have improved tremendously in the past decade. Regulatory initiatives from the Central Bank have also played a large role in the banking sector. Robust technology-enabled organizations have now become the mainstay of the industry. Initiatives such as electronic clearing service (ECS), national electronic funds transfer (NEFT), real-time gross...

...the different stakeholders, and in practice, the target of the manipulation appears generally to be the earnings per share and the debt/equity ratio. The paper also describes the different actors involved and their potential gains and losses. We review the literature on the various techniques of accounts manipulation: earnings management, income smoothing, big bath accounting, creative accounting, and window-dressing. The various definitions of all these, the main motivations behind their application and the research methodologies used are all examined. This study reveals that all the above techniques have common elements, but there are also important differences between them. I. Introduction Finns have been manipulating accounts for a long time, and this practice, well known in the literature, has been given various names: earnings management, income smoothing, big bath accounting, creative accounting, and window dressing. This paper aims to provide a comprehensive review of the literature and propose a conceptual framework for accounts...
