Fighting online fraud with AI

AI News acquired Siddhartha Choudhury, the director of the upper products at Booking.com, to get an internal script on how to maintain your reservations – and data – safe from security threats such as online fraud.

When you book online vacation, you put a lot of confidence on the website. You trust your money, personal details and travel plans. For a giant like Booking.com, keeping confidence for millions of people every day is a huge function. So, how do they do that? Increasingly, the answer is Amnesty International.

The confrontation of modern fraud requires the assistant of Amnesty International

It is difficult to wrap the amount of Data Booking.com. This is not only about preventing someone from using stolen credit card; The platform must discover everything from fake hotels reviews and marketing fraud to hunting and acquisition attacks.

“We use artificial intelligence for a wide range of risk use in safety and fraud,” explained Ch Xodry. “Here, we deal with Petabytes from the data that includes events created from applications, infrastructure, messages and email messages …”

To deal with this, they do not depend on one magic tool. “We also benefit from multiple compact ML solutions from sellers and internal solutions together to determine and alleviate fraudulent attacks,” added Ch Xodry.

In short, they combine the best ready -made programs with artificial intelligence specifically designed to create a strong safety cocktail, protect both travelers and real estate owners on the platform.

A million dollar question: Best or cheaper?

Of course, running a safety system on this scale is not easy. One of the largest headaches is simply obtaining all the different tools, interior and exterior, to play well. But Chaudhry pointed to a more strict and more continuous budget action: performance for cost.

Electronic attacks become more intelligent every day, which means that your defenses constantly need improvement. But the best technology costs more money.

“Because of the advanced electronic threats, the attacks are more sophisticated and the database is constantly increasing,” says Chuoderi. “So the decision is: Do we have to make things more efficient, or do we need to make them better?”

How artificial intelligence helps to advance online fraud threats

It is often said the best defense is a good crime. Instead of responding to problems after they occur, Booking.com uses Amnesty International to discover troubles before it begins. A large part of this guarantees the transfer of their systems to the cloud, allowing the most intelligent and faster tools.

Chaudrei explained that human security experts now have a team of digital assistants. “The multiple Amnesty International assistants are parallel to security analysts to improve their efficiency and reduce operational toil,” he explains.

By giving the best human investigators a digital partner that can sort mountains from clues in seconds, experts can focus their skills on the most important threats, while strong monitoring systems make sure that artificial intelligence itself works smoothly and accurately.

Ensure that AI plays fair

When artificial intelligence gives the ability to make important security decisions, you should incredibly be careful that it does not become unfair. Chaudhry was clear that ethics are at the heart of its strategy, which was built on some of the main ideas:

• Equity: The company is actively examining Amnesty International for biases to ensure that it does not mark in some people or groups in an unfair way for possible fraud online.

• Human oversight: This is a big one. For any major decision, “there is enough human participation to determine the wrong positives.” A person, not just a program, often gets the final statement.

• to explain: Artificial intelligence cannot be a mysterious “black box”. The team needs to understand the reason for making a specific decision to ensure accountability.

• privacy: Of course, everything has been built on a solid basis from “protecting strong data, privacy and compliance”, always with the user consent.

What is on the horizon?

CHOUDHURY believes that the following big jump is not related to finding new things to do artificial intelligence, but about making all current artificial intelligence tools work together efficiently.

“I expect more and more solutions to be designed, but I also expect to be organized in a way that makes the departments more efficient,” Chaudri expects.

The goal is to build a system where all security and cooperation spare parts continue intelligently. For Booking.com, the task is clear: “Driving innovation along with reliability and cost efficiency will be the main focus.”

As for our rest, artificial intelligence gives us peace of mind a little more, we will not become victims of online fraud after clicking on a “book” on that vacation.

Siddhartha Chudhury and Booking.com will share more ideas in Ai & Big Data Expo in Amsterdam on September 24-25, 2025. Chaudri will speak as part of a committee entitled ” “Innovation on a large scale: GEN AI, cloud platforms, data -based development” On the second day of the pioneering industry event.
