That's a sharp improvement from 2005, when the company's previous analytic engine could study only 40 aspects at once. The new analytic engine can study as many as 500 aspects of a transaction at once. While one transaction at a merchant might not look suspicious, a data set that includes hundreds or thousands of transactions makes it easier to spot a problem, such as a tampered PIN pad. Visa said that the larger data set helps it identify fraud more quickly. Visa said that while this information is connected to a specific card number, "it's not personally identifiable in the Visa system." The company is also on alert for other warning signs such as orders in which the billing and shipping address are different. It determined, for example, that in certain merchant categories, for transactions of $200 or more, prepaid cards were included in 85% of cases that turned out to be fraudulent. Visa said it can identify high-risk purchases such as big screen TVs and prepaid cards, that can easily be converted to cash. In the past, the company based its security assumptions on average fraud rates for merchant categories, like grocery stores. Now it said it can analyze the actual market, right down to individual merchant terminals. That allows it to drill down on hundreds of attributes, such as average authorization volumes, average ticket sizes and frequency of purchases that turn out to be fraudulent, the company said. Now the company said it endeavors to analyze all of its data. However, 6 cents out of every $100 in transactions are believed to be fraudulent.Įarlier analytic models studied as little as 2% of transaction data. In 2005, it added advanced authorization techniques, in which a customer may be asked to provide more than a simple password. Fraud has declined by two thirds, during that period of time. Visa's fraud detection efforts moved into the digital world 20 years ago, when the authorization system went online. The company estimates that the model has identified $2 billion in potential annual incremental fraud opportunities, and given it the chance to address those vulnerabilities before that money was lost. The analytic platform harnesses the power of Big Data-a term that refers to larger and more varied set of data, powerful algorithms, and underlying hardware and software that runs calculations faster and more cheaply than traditional databases or analytic engines. To confront the risk, Visa introduced a new analytic engine in August 2011, which she says has changed the way the company combats fraud. The company risks losing trust, and standing, with its customers – something it cannot afford to let happen in an increasingly competitive payments market. No company-and certainly not Visa, the credit and debit card processing giant-can afford to "stand still," Richey says. "They are getting into the systems of stakeholders and other companies that process payments, and they are able to encrypt their own movements on networks, sometimes for months, and exfiltrate the data." "You see the criminal capability evolving on the technology side," she said. The Crane API enables."We are confronting a criminal population that continues to improve its sophistication and its attack vectors, so we can't stand still," says Ellen Richey, chief enterprise risk officer at Paper Crane is a Geospatial Intelligence Platform that unifies geospatial data, generates variables through spatial feature engineering, and improves machine learning models. The API returns products, reviews, offers, search results, autocomplete results and category. It is not officially assoicated with Walmart.
