Currency security and forensics: a survey

By its definition, the word currency refers to an agreed medium for exchange, a nation’s currency is the formal medium enforced by the elected governing entity. Throughout history, issuers have faced one common threat: counterfeiting. Despite technological advancements, overcoming counterfeit production remains a distant future. Scientific determination of authenticity requires a deep understanding of the raw materials and manufacturing processes involved. This survey serves as a synthesis of the current literature to understand the technology and the mechanics involved in currency manufacture and security, whilst identifying gaps in the current literature. Ultimately, a robust currency is desire

Cryptocurrencies and future financial crime.

Background: Cryptocurrency fraud has become a growing global concern, with various governments reporting an increase in the frequency of and losses from cryptocurrency scams. Despite increasing fraudulent activity involving cryptocurrencies, research on the potential of cryptocurrencies for fraud has not been examined in a systematic study. This review examines the current state of knowledge about what kinds of cryptocurrency fraud currently exist, or are expected to exist in the future, and provides comprehensive definitions of the frauds identified. Methods: The study involved a scoping review of academic research and grey literature on cryptocurrency fraud and a 1.5-day expert consensus exercise. The review followed the PRISMA-ScR protocol, with eligibility criteria based on language, publication type, relevance to cryptocurrency fraud, and evidence provided. Researchers screened 391 academic records, 106 of which went on to the eligibility phase, and 63 of which were ultimately analysed. We screened 394 grey literature sources, 128 of which passed on to the eligibility phase, and 53 of which were included in our review. The expert consensus exercise was attended by high-profile participants from the private sector, government, and academia. It involved problem planning and analysis activities and discussion about the future of cryptocurrency crime. Results: The academic literature identified 29 different types of cryptocurrency fraud; the grey literature discussed 32 types, 14 of which were not identified in the academic literature (i.e., 47 unique types in total). Ponzi schemes and (synonymous) high yield investment programmes were most discussed across all literature. Participants in the expert consensus exercise ranked pump-and-dump schemes and ransomware as the most profitable and feasible threats, though pump-and-dumps were, notably, perceived as the least harmful type of fraud. Conclusions: The findings of this scoping review suggest cryptocurrency fraud research is rapidly developing in volume and breadth, though we remain at an early stage of thinking about future problems and scenarios involving cryptocurrencies. The findings of this work emphasise the need for better collaboration across sectors and consensus on definitions surrounding cryptocurrency fraud to address the problems identified

LEGAL REMARKS ON THE OVERARCHING COMPLEXITIES OF CRYPTO ANTI-MONEY LAUNDERING REGULATION

ABSTRACT Objective:The paper analyzes money laundering through crypto-assets and offers a legal perspective on how this new technology can be used to commit these felonies. The study intends to shed light on the matter, helping to visualize how future anti money laundering – AML regulation should focus on tackling crypto criminal activity effectively. Methodology: The research adopts an inductive approach, bibliographic and documental research technique, with an exploratory and propositional methodological objective. Results: The paper proposes the following framework of anti-money laundering principles for crypto-focused action: transnational approach for AML action; going beyond basic gatekeeper compliance approach, considering the lack of structural chokepoints in a blockchain protocol; private-sector cooperation and clear AML standards; usage of tracking and reverse-engineering anonymization techniques for the tracing of crypto transaction history; and adoption of a global blacklist for cryptoasset prefixes, preventing money laundering integration. Contributions: The study addresses a topic that is still unfamiliar in the academic world due to its innovation and complexity, as well as elaborates a set of principles to combat money laundering with crypto-assets that could be of great value to companies and financial institutions. KEYWORDS: Crypto-assets; crypto-currencies; bitcoin; blockchain; money laundering. RESUMO Objetivos: O artigo analisa a lavagem de dinheiro através de ativos criptográficos e oferece uma perspectiva jurídica sobre como essa nova tecnologia pode ser usada para cometer tais crimes. O estudo busca esclarecer o assunto, ajudando a visualizar como a futura regulação contra a lavagem de dinheiro cometida através destes ativos deve ser estruturada para assegurar efetividade. Metodologia: A pesquisa adota uma abordagem indutiva, a técnica de pesquisa é bibliográfica e documental, seu objetivo metodológico é exploratório e propositivo. Resultados: O artigo propõe o seguinte conjunto de princípios para o combate à lavagem de dinheiro com criptoativos: a abordagem transacional para combate à lavagem de dinheiro; ir além de uma abordagem focada em intermediários, considerando a falta de pontos de estrangulamento em um protocolo block chain; a cooperação com o setor privado e padrões claros de compliance para prevenção à lavagem de dinheiro; uso de técnicas de rastreamento e de engenharia reversa para processos de ocultação de histórico de transações; e a adoção de listas sujas globais para evitar a fase de integração do processo de lavagem de dinheiro com criptoativos.Contribuições: O estudo aborda um tema ainda muito pouco divulgado no meio acadêmico devido à sua inovação e complexidade, bem como elabora uma proposta de conjunto de princípios para o combate à lavagem de dinheiro com criptoativos que poderá ser de grande valia para empresas e instituições financeiras. PALAVRAS-CHAVE: Criptoativos; criptomoedas; bitcoin; blockchain; lavagem de dinheiro

ADABOOST RANDOM FOREST OPTIMAL SELECTION ALGORITHM STUDY ON THE FINANCIAL STATEMENT BASED EMOTIONAL LEVEL ANALYSIS USING DATA MINING APPROACH

This article suggests that AdaBoost create a viable growth survival expectation model that computes a combination and spontaneity approx. The AdaBoost of Irregular Wilderness improves accuracy and reliability and encourages unsupported students to choose high-weighted cases in the rotation process to minimize problem-fitting. In this half, the reproduction strategy's efficiency (for example, accuracy, affectability, and clarity) is evaluated using the required performance ratings. They propose the novel point of view of AdaBoost and the Spontaneous Woodland view showing the reason for comparing the two calculations. Although the two classifications' comparison prophecy is complete, the irregular difficulty cannot be considered a direct approach. Average self-disorderly suburban areas, and help us "soften the edges" will allow us to reveal the classification introduced in the calculations; they should see the light of similar AdaBoost. In light of the success of this system is not AdaBoost and arbitrary brutality think. Different instructions to help with these explanations. Simultaneously, the way an suggest that to improve standard calculations of thought, it should be adjusted or discontinued early, and students in low-processing classes should only, for example, question the choice of stumps. The pressurization, infer that use unusually shaped woodland: Financial speculation who will not be replaced by a large appointment of trees or will stop the existence of financial data in advance down to the great steps of implementing electronic structures today. Investigate the reasons for doing this. During the hearing, the board of directors asked if the rehearsal bookkeeper felt any negative emotions while restricting personal income from the board. Ranging from the board of directors demanded a functional exercise, bookkeeper angry and helpless, had to sigh, found due to false statements in financial reports. Analyze the implications of these findings
