It enables many of the complex systems we take for granted-such as telecommunications networks and scheduling for fleets of delivery vehicles or airline flights-to work as efficiently and inexpensively as possible. The pair had been trying to discover a way to improve the simplex method, one of the most widely used algorithms in the world. I thought of throwing away my research program.вЂќ And in that instant, the cards collapsed. вЂњAs I was sitting there waiting-fortunately not to get picked-I had this awful experience of realizing everything weвЂ™d been doing was wrong. вЂњIвЂ™ll never forget,вЂќ says Spielman, an associate professor of mathematics. ThatвЂ™s why we use minFraud.While sitting in a courtroom, waiting to find out if he would be chosen for jury duty, Daniel Spielman had a revelation-all the work he and colleague Shanghua Teng had built up over the past three years was a house of cards. вЂњThe quality of the data is really important to us. In the end, whether theyвЂ™re building a fraud detection algorithm or manually reviewing transactions, it all comes down to the data. When a customer claims that a transaction is fraudulent, Simplex fraud investigators can check the details of their customerвЂ™s story against the data returned by minFraud, to confirm their story or ask more questions if the data and the story donвЂ™t seem to line up.ДЄlong with a powerful algorithm, SimplexвЂ™s analysts use minFraud Insights data to protect the integrity of their clientsвЂ™ transactions and reduce costs due to chargebacks. The data from minFraud Insights also helps Simplex to dig into particular claims of fraud, allowing their fraud prevention specialists to avoid erroneous chargebacks and investigate issues thoroughly when they arise.

вЂњWe also make minFraud data available to our fraud analysts for manual review of transactions.вЂќ This adaptability is key to fighting fraud in the rapidly changing crypto industry. Rather than trying to anticipate which data points will be most relevant to fraud, Simplex can feed the breadth of minFraud data into their algorithm, allowing it to identify and adapt to patterns in fraud as they emerge. The variety of data available through minFraud Insights allows Simplex to track patterns across many different data points. More data means that we can do better research.вЂќ

вЂњThe more data I have, the more significant my results can be. They decided to implement minFraud because, in addition to a risk score, the minFraud Insights service gave them access to a breadth of high quality data on inputs ranging from IP geolocation and email risk to financial institution data, all via a flexible easy-to-use API.

If we had to update these rules manually in response to emerging trends, our workflow would be very slow and inefficient.вЂќДЇor the analysts who work on SimplexвЂ™s fraud detection algorithm, data is key to a responsive algorithm. We might use simple IP geolocation and look at the distances involved in the transaction, or rely solely on one risk score. Without an adaptive risk model, we would have to rely on a strict rule-based system. вЂњIn the crypto market, everything changes quickly. Simplex Data Analyst Talor Kars works closely with that algorithm. When they were putting together their platform, they knew from the beginning that they would need an agile, responsive algorithm at the heart of their fraud detection and prevention solutions. With a zero chargeback guarantee in place, thereвЂ™s a lot at stake in fraud detection and prevention. As the market leader, they pioneered the first riskless global fiat onramp using a credit and debit card, which promises a zero chargeback guarantee. Simplex has been changing the status quo of crypto purchases since 2014.
