Ask an AI model if the extracted line item price is within the expected price range for this product/service. If it's not, this could be a fraud indicator. For example: iphone repair for €2000. A service like that would normally cost around €50.
Alongside the document/image, send in additional information with the request to validate against. For example, send a list of allowed phone brands with which the image has to be taken, or send in countries to be validated with geodata from the EXIF.
