AI Event Registration Fraud and Anomaly Detector

Detect suspicious event registrations with AI: duplicates, bots, disposable emails and unusual spikes that point to fraud.

Registrations to check

One row per registrant. At least five rows are needed: the check works by comparing registrations with each other.

This calculation needs at least 5 registrations: add 5 more registrations.

The columns must be in the same order as the fields above, and they replace the rows already entered. A list in JSON format also works, if you have one.

How it works

Upload your event registration data and the AI automatically identifies suspicious anomalies: duplicate registrations, bot patterns, disposable emails, unusual spikes and fraudulent behaviour. Protect the integrity of your sign-ups with automatic detection of irregularities.

Frequently asked questions

What anomalies does the tool detect?

The tool identifies: multiple registrations from the same IP address, disposable or suspicious-looking email addresses, unnatural spikes of sign-ups within a few minutes, inconsistent personal data, typical automated bot patterns and registrations with repeatedly declined credit cards.

How does it tell legitimate registrations from anomalous ones?

The anomaly detection algorithm learns the "normal" registration pattern (timing, geolocation, user behaviour) and flags significant deviations. Each anomaly gets a risk score to help you decide what action to take.

What should you do when an anomaly is detected?

The tool suggests graduated actions: manual review for medium risk, temporary block for high risk and immediate reporting for clearly fraudulent patterns. Each anomaly comes with the reason and the supporting data.
