GARCIA NUNEZ, Alejandro  e  OLMEDO FLORES, Jorge Luis. High-availability distributed architecture for fraud detection. Rev cuba cienc informat [online]. 2021, vol.15, n.4, suppl.1, pp. 199-224.  Epub 01-Dez-2021. ISSN 2227-1899.

Early, fast and effective fraud detection in the telecommunications sector has become the spearhead for dealing with the most complex and diverse ways in which attacks and fraud can occur. Different techniques, tools and algorithms are used for detection, such as machine learning, which is a branch of Artificial Intelligence that allows computers to learn. In order to take full advantage of the benefits of machine learning, robust hardware and software architectures are set up. These are configured in a distributed manner allowing a set of computers to work as one in a transparent way, increasing performance and processing. The objective of this work is to develop a highly available distributed architecture using the Hortonworks data platform that allows the application of machine learning techniques in fraud detection. Apache components such as Spark, HBase and Hadoop were installed and configured to analyze traffic in large amounts of data. An example of the result of applying the K-means machine learning algorithm using the PySpark library for the creation of clusters is shown. The installation and configuration of the Hortonworks data platform resulted in an architecture that is highly available, flexible, scalable, fault tolerant and allows the use of machine learning for fraud detection.
