Fraud detection - Waiviogit/waivio GitHub Wiki

Technology for detecting fraud attempts in reviews. The tab displays the results of the Fraud detection assistant.
Page for displaying campaigns where “dubious” photos were identified in review.

A tab is added under the Rewards / Campaigns section and is accompanied by a disclaimer stating that this is an experimental service only and should not be relied upon.

If no cases are found, then the message is displayed: "Fraud attempts have not been detected."

The selection of cards is limited to 30 days.

At the moment, the check is carried out as follows:

1. the models of the devices on which the pictures for the review were taken are compared, if they differ, the user is suspected of fraud.
2. if the image has gps coordinates, then it is checked that they are made within a radius of 1 km from the restaurant (provided that the object has a map)
3. the date of creation of the image is checked - it must be no earlier than 14 days before the reservation of the company.
