From cheating to teaching: a path for conversion of illegal gambling machines

Video poker machines, a former symbol of fraud and gambling in Brazil, are now being converted into computer-based educational tools for Brazilian public primary schools and also for governmental and non-governmental institutions dealing with communities of poverty and social exclusion, in an attempt to reduce poverty risks (decrease money spent on gambling) and promote social inclusion (increase access and motivation to education). Thousands of illegal gambling machines are seized by federal authorities, in Brazil, every year, and usually destroyed at the end of the criminal apprehension process. This paper describes a project developed by the University of Southern Santa Catarina, Brazil, responsible for the conversion process of gambling machines, and the social inclusion opportunities derived from it. All project members worked on a volunteer basis, seeking to promote social inclusion of Brazilian young boys and girls, namely through digital inclusion. So far, the project has been able to convert over 200 gambling machines and install them in over 40 public primary schools, thus directly benefiting more than 12,000 schoolchildren. The initial motivation behind this project was technology based, however the different options arising from the conversion process of the gambling machines have also motivated a rather innovative and unique experience in allowing schoolchildren and young people with special (educational) needs to access to computer-based pedagogical applications. The availability of these converted machines also helps to place Information and Communication Technologies (ICT) in the very daily educational environment of these children and youngsters, thus serving social and cultural inclusion aspects, by establishing a dialogue with the community and their technological expectations, and also directly contributing to their digital literacy.

Combate à fraude em jogos de casino, assistida por computador

No decorrer dos últimos anos tem-se verificado um acréscimo do número de sistemas de videovigilância presentes nos mais diversos ambientes, sendo que estes se encontram cada vez mais sofisticados. Os casinos são um exemplo bastante popular da utilização destes sistemas sofisticados, sendo que vários casinos, hoje em dia, utilizam câmeras para controlo automático das suas operações de jogo. No entanto, atualmente existem vários tipos de jogos em que o controlo automático ainda não se encontra disponível, sendo um destes, o jogo Banca Francesa. A presente dissertação tem como objetivo propor um conjunto de algoritmos idealizados para um sistema de controlo e gestão do jogo de casino Banca Francesa através do auxílio de componentes pertencentes à área da computação visual, tendo em conta os contributos mais relevantes e existentes na área, elaborados por investigadores e entidades relacionadas. No decorrer desta dissertação são apresentados quatro módulos distintos, os quais têm como objetivo auxiliar os casinos a prevenir o acontecimento de fraudes durante o decorrer das suas operações, assim como auxiliar na recolha automática de resultados de jogo. Os quatro módulos apresentados são os seguintes: Dice Sample Generator – Módulo proposto para criação de casos de teste em grande escala; Dice Sample Analyzer – Módulo proposto para a deteção de resultados de jogo; Dice Calibration – Módulo proposto para calibração automática do sistema; Motion Detection – Módulo proposto para a deteção de fraude no jogo. Por fim, para cada um dos módulos, é apresentado um conjunto de testes e análises de modo a verificar se é possível provar o conceito para cada uma das propostas apresentadas.

Status of Non-Technical Losses of Electricity in Brazil

The electricity demand in Brazil has been growing. Some studies estimate that through 2035 the energy consumption (the power consumption) should increase 78%. Two distinct actions are necessary to meet this growth: the construction of new generating plants and to reduce electrical losses in the country. As the construction of power plants have a high price, coupled with the growth of (current) environmental concern, electric utilities are investing in reducing losses, both technical and non-technical. In this context, this paper aims to present an overview of nontechnical losses in Brazil and to raise a discussion on the reasons that contribute to energy fraud.

Study of Proposed Identification of Non-Technical Losses of Electricity in Brazil

The electric utilities have large revenue losses annually due to commercial losses, which are caused mainly by fraud on the part of consumers and faulty meters. Automatic detection of such losses where there is a complex problem, given the large number of consumers and the high cost of each inspection, not to mention the wear of the relationship between company and consumer. Given the above, this paper aims to briefly present some methodologies applied by utilities to identify consumer frauds.

Home Banking

The object of this dissertation is focused on the study of the home banking service and how the allocation of losses due to computer fraud is processed in the scope of this service. When considering the questions raised by the allocation of losses associated with fraudulent operations, it is important to consider, mainly, the behaviour of the user of the home banking service. In our opinion, courts have been too demanding towards the user when judging his action in the use of this service. In this study, we have concluded that, when the user “falls” into a computer fraud scheme, he should not be liable for gross negligent behaviour, even if, due to the fraud, the user revealed all his access codes to a hacker on a page similar to that of his bank. In general, such facts will not be sufficient to qualify the user’s action as grossly negligent. Therefore, the user, under the terms of the Payment Services’ System, must bear the loss up to a maximum of €150, and the bank will face the remainder of the losses. However, if the user, victim of a fraudulent technique, ignored the safety warnings issued by the bank, one must consider, given the specific case, that he contributed to gross negligence in unauthorised payment transactions. Thus, the user must bear all the losses up to the moment when he notifies the bank about the unauthorised transactions. It is the bank’s responsibility to, given the specific case, adduce evidence of the client’s contribution to the identified losses.

O sigilo bancário e a fraude fiscal

Tax evasion and fraud threaten the economic and social objectives of modern tax systems, precluding the state funding for the satisfaction of collective needs and the fair distribution of wealth, being a violation of basic principles and values of our society. In tax law, to give tax administration the necessary powers to supervise and control the information provided by taxpayers and combat tax evasion and fraud, over the last years the grounds for a derogation of bank secrecy without judicial authorization have been extended, which raises some constitutional compatibility issues. Similarly, this tendency of making this legal regime more flexible and increasing automatic exchange of information has been followed by the European Union and the international community. Banking secrecy, as a professional secrecy, is an instrument to protect the right to privacy but also appears as an anti-abuse and repressive mechanism of evasive and fraudulent behaviors. Because of the conflict of interests will always be necessary to make a practical agreement between them, ensuring the legality and the due guarantees of the taxpayers but also an effective way to combat tax evasion and fraud. Bank secrecy cannot be one method to, behind the right to privacy, taxpayers practice illegal activities. But the practice of these irregular conducts also does not justify a total annihilation of the right to banking secrecy, uncovering all documents and bank information’s. Although considering the legislative changes, the administrative derogation of bank secrecy will always be what the tax administration does of it.
