Because of AI’s nonstop enchancment, it’s changing into troublesome for people to identify deepfakes in a dependable method. This poses a significant issue for any type of authentication that depends on photos of the trusted particular person. Nonetheless, some approaches to countering the deepfake risk present promise.
A deepfake, which is a portmanteau of “deep studying” and “pretend,” could be any {photograph}, video, or audio that’s been edited in a misleading method. The primary deepfake could be traced again to 1997, when a mission referred to as Video Rewrite demonstrated that it was potential to reanimate video of somebody’s face to insert phrases that they didn’t say.
Early deepfakes required appreciable technological sophistication on the a part of the person, however that’s not true in 2025. Because of generative AI applied sciences and strategies, like diffusion fashions that create photos and generative adversarial networks (GANs) that make them look extra plausible, it’s now potential for anybody to create a deepfake utilizing open supply instruments.
The prepared availability of subtle deepfakes instruments poses severe repercussions for privateness and safety. Society suffers when deepfake tech is used to create issues like pretend information, hoaxes, youngster sexual abuse materials, and revenge porn. A number of payments have been proposed within the U.S. Congress and several other state legislatures that might criminalize using expertise on this method.
The influence on the monetary world can also be fairly important, largely due to how a lot we depend on authentication for crucial providers, like opening a checking account or withdrawing cash. Whereas utilizing biometric authentication mechanisms, reminiscent of facial recognition, can present better assurance than passwords or multi-factor authentication (MFA) approaches, the fact is that any authentication mechanism that depends on photos or video partly to show the identification of a person is weak to being spoofed with a deepfake.

Fraudsters, ever the opportunists, have readily picked up deepfake instruments. A latest research by Signicat discovered that deepfakes have been utilized in 6.5% of fraud makes an attempt in 2024, up from lower than 1% makes an attempt in 2021, representing greater than a 2,100% enhance in nominal phrases. Over the identical interval, fraud usually was up 80%, whereas identification fraud was up 74%, it discovered.
“AI is about to allow extra subtle fraud, at a better scale than ever seen earlier than,” Seek the advice of Hyperion CEO Steve Pannifer and International Ambassador David Birch wrote within the Signicat report, titled “The Battle Towards AI-driven Identification Fraud.” “Fraud is prone to be extra profitable, however even when success charges keep regular, the sheer quantity of makes an attempt implies that fraud ranges are set to blow up.”
The risk posed by deepfakes just isn’t theoretical, and fraudsters presently are going after giant monetary establishments. Quite a few scams have been cataloged within the Monetary Providers Info Sharing and Evaluation Heart’s 185-page report.
As an example, a pretend video of an explosion on the Pentagon in Might 2023 brought about the Dow Jones to fall 85 factors in 4 minute. There may be additionally the fascinating case of the North Korean who created pretend identification paperwork and fooled KnowBe4–the safety consciousness agency co-founded by the hacker Kevin Mitnick (who died in 2023)–into hiring her or him in July 2024. “If it will probably occur to us, it will probably occur to nearly anybody,” KnowBe4 wrote in its weblog publish. “Don’t let it occur to you.”
Nonetheless, probably the most well-known deepfake incident arguably occurred in February 2024, when a finance clerk at a giant Hong Kong firm was tricked when fraudsters staged a pretend video name to debate the switch of funds. The deepfake video was so plausible that the clerk wired them $25 million.
iProov developed patented flashmark expertise to detect deepfakes (Picture supply: iProov)
There are a whole bunch of deepfake assaults day by day, says Andrew Newell, the chief scientific officer at iProov. “The risk actors on the market, the speed at which they undertake the assorted instruments, is extraordinarily speedy certainly,” Newell stated.
The massive shift that iProov has seen over the previous two years is the sophistication of the deepfake assaults. Beforehand, using deepfakes “required fairly a excessive stage of experience to launch, which meant that some individuals may do them however they have been pretty uncommon,” Newell advised BigDATAwire. “There’s a complete new class of instruments which make the job extremely straightforward. You could be up and operating in an hour.”
iProov develops biometric authentication software program that’s designed to counter the rising effectiveness of deepfakes in distant on-line environments. For probably the most high-risk customers and environments, iProov makes use of a proprietary flashmark expertise throughout sign-in. By flashing totally different coloured lights from the person’s system onto his or her face, iProov can decide the “liveness” of the person, thereby detecting whether or not the face is actual or a deepfake or a face-swap.
It’s all about placing roadblocks in entrance of would-be deepfake fraudsters, Newell says.
“What you’re attempting to do is to be sure to have a sign that’s as complicated as you probably can, while making the duty of the tip person so simple as you probably can,” he says. “The best way that mild bounces off a face it’s extremely complicated. And since the sequence of colours really adjustments each time, it means in case you attempt to pretend it, that you need to pretend it nearly in precise actual time.”
The authentication firm AuthID makes use of quite a lot of strategies to detect the liveness of people in the course of the authentication course of to defeat deepfake presentation assaults.

“We begin with passive liveness detection, to find out that the id in addition to the individual in entrance of the digital camera are actually current, in actual time. We detect printouts, display replays, and movies,” the corporate writes in its white paper, “Deepfakes Counter-Measures 2025.” “Most significantly, our market-leading expertise examines each the seen and invisible artifacts current in deepfakes.”
Defeating injection assaults–the place the digital camera is bypassed and faux photos are inserted straight into computer systems–is more durable. AuthID makes use of a number of strategies, together with figuring out the integrity of the system, analyzing photos for indicators of fabrication, and on the lookout for anomalous exercise, reminiscent of validating photos that arrive on the server.
“If [the image] reveals up with out the fitting credentials, so to talk, it’s not legitimate,” the corporate writes within the white paper. “This implies coordination of a form between the entrance finish and the again. The server aspect must know what the entrance finish is sending, with a kind of signature. On this manner, the ultimate payload comes with a star of approval, indicating its legit provenance.”
The AI expertise that permits deepfake assaults is liable to enhance sooner or later. That’s placing strain on firms to take steps to fortify their authentication course of now or danger letting the incorrect individuals into their operation.
