Our Client, one of the Top 3 biggest Bank in Indonesia, launched their Mobile Banking many years back. During that time they needed a Fraud Analytic platform to assist them with their day to day analysis on any fraudulent transaction on their platform. We used Splunk back then and it was successful.
Recently they need to expand their capability in Fraud Analytic and they need a Rule Engine that is easy to use, expandable, flexible, fast, and reliable correlation of information from multiple and varied sources to be integrated with their Front End for remote Analyst. So, in 2023 we embarked on refreshing the whole platform with new capabilities. Our solution is using Splunk Core with custom data model and API extension to interact with the Front End Server. Together with the client, we develop custom simple logic language for rule admin that is low code, requires no prior SPL knowledge for the admin to operate.
The Rule Engine was first introduced to handle fraud on a single channel and quickly becoming the base Engine of choice for multiple channel used to analyze fraud giving the capability of Advanced Detection and Complex Analysis. As new channels starts being integrated, our client requested more analytic capabilities requiring higher mathematical algorithm to solve.
Working together with client, our analysis expert recommend calculation, algorithm, and technique that would be suitable as well as consulting our client of the cautionary tale that should be considered when running the analysis into production and its integration with the daily operation.
The original Solution was implemented successfully towards the end of 2023 and now we are embarking on building additional functions and capabilities surrounding the original solution.
