This month, Chatgpt revealed a new image generator as part of its 4o model which is much better in generating text within the images.
People are already using it to generate fake restaurant bills, potentially adding another tool to the already elongated deepfake tool used by fraudsters.
Poster of fruitful social media and QV Deedy Das posted on X a photo of a fake bill for a (real) San Francisco steakhouse that he says was created with 4o.
Others were able to repeat similar results, including one with food stains or drinks to make it look even more authentic:
The most true example found Techcrunch found was actually from France, where a Linkedin user posted a bill produced by him for a local restaurant chain:
Techcrunch tested 4o and was also able to generate a fake bill for an Applebee in San Francisco:
But our attempt had some dead gifts that it was forged. For one, the total uses a comma instead of a period. For another, math is not increased. LLM still struggles to make basic mathematics, so this is not particularly startling.
But it would not be difficult for a rogue to quickly adjust some of the numbers with or software to edit photos or, perhaps, more accurate instructions.
It is clear that making it really easy generating fake bills presents great opportunities for fraud. It would not be difficult to imagine that this kind of technology used by bad actors to “refund” for completely false expenses.
Openai spokesman Taya Christianon told Techcrunch that all of her images include metadata showing that they were made by chatgpt. Christianon added that Openai “takes action” when users violate his use policies and that he is “always learning” from the use and reaction of the real world.
Techcrunch then asked why chatgpt allows people to generate fake bills in the first place, and whether this is in line with Openai’s use policies (which stop fraud.)
Christianon replied that “Openai’s goal is to give users as much creative freedom as possible” and that fake bills of it can be used in non-deceived situations such as “teaching people about financial literacy” along with the creation of original art and products advertising.
