Artificial intelligence is revolutionizing identity verification much like it is reshaping countless other industries. Both public and private sectors are increasingly embracing AI to enhance the accuracy and speed of verifying identities. But alongside its benefits, AI has also become a powerful enabler of fraud, with criminals weaponizing it to forge identities and produce convincing deepfakes.
This article explores the dual nature of AI in identity verification—highlighting how it strengthens defenses through biometric recognition, liveness detection, and fraud prevention, while also exposing how it can be exploited to deceive systems.
The Upside: Enhancing Identity Verification with AI
Over the last decade, AI has significantly elevated the precision, security, and efficiency of identity verification methods. While it’s best not to rely on tools like ChatGPT for document validation, AI offers tangible advantages when applied through the right channels.
Smarter Biometric Matching
AI has brought major improvements to biometric technologies such as facial, fingerprint, and voice recognition. These systems now rely on AI to accurately map and compare facial structures with those in official ID documents or stored profiles.
In the United States, the Department of Homeland Security reports high success rates using AI-powered facial recognition—achieving up to 97% accuracy across 14 different applications. Meanwhile, Europe has adopted a cautious but proactive approach. The EU AI Act, which took effect on August 1, 2024, introduces a phased rollout with full enforcement by August 2027. Under this legislation, systems tied to identity verification—like automated CV screening and border control—are labeled “high-risk.”
To comply, organizations must:
Conduct risk assessments and maintain detailed system logs.
Use unbiased, high-quality training data for AI models.
Guarantee human oversight in identity verification workflows.
Liveness Detection for Real-Time Validation
One of the simplest tricks fraudsters attempt is using a static photo or video to spoof a live verification. AI thwarts this through liveness detection—a method that evaluates physical signals like blinking, subtle movements, depth perception, and facial texture to confirm the presence of a real person.
Such indicators are hard to fake convincingly, and many digital ID verification solutions now incorporate liveness checks during onboarding. Users may be asked to turn their heads or perform gestures to prove they’re physically present.
AI-Powered Document Verification
Instead of relying on manual reviews, which are time-consuming and prone to error, AI can instantly analyze a wide range of ID documents—passports, driver’s licenses, and national IDs among them.
Neural networks and computer vision tools scan for embedded security features (like holograms or optically variable inks) and extract text using OCR. This information is then cross-checked against databases of genuine document templates to spot signs of forgery or tampering.
The Downside: AI-Driven Threats to Identity Verification
Despite its defensive capabilities, AI has also introduced sophisticated tools for identity fraud. Criminals use it to forge synthetic identities, bypass biometric checks, and generate deepfakes that can fool both humans and machines.
Deepfake Fraud: The Imitation Game
Deepfakes are one of the most alarming threats in this space—realistic audio, video, or image fabrications that mimic real individuals. Some are so advanced they can even pass live verification.
A high-profile case from early 2024 saw fraudsters impersonate a company’s CFO using a video deepfake. During a video call, the attackers—posing as the CFO—convinced a finance employee to transfer $25 million to fraudulent accounts. It was only discovered after the money was gone.
Reports throughout 2024 have confirmed that biometric systems relying on facial or voice recognition have been successfully deceived using these techniques.
Synthetic Identity Fraud: Fiction Built from Fact
Another dangerous form of fraud is the creation of synthetic identities—combinations of real and fabricated personal information used to create entirely fictitious people.
With the help of AI, fraudsters can now generate unique profile photos and fake documents that won’t raise suspicion in reverse image searches. Our recent research found that nearly half of businesses in the US (49%) and the UAE (51%) have encountered synthetic identities during customer onboarding.
To illustrate the ease of this process: in a 2024 investigation, a journalist used a shady AI service to generate a realistic fake driver’s license using a made-up identity and his own photo—for just $15. The forged document passed a crypto exchange’s KYC checks.
False Positives: When AI Gets It Wrong
False positives aren’t acts of fraud, but they’re still damaging. AI systems occasionally misidentify legitimate users as threats, often due to lighting inconsistencies, aging photos, or model limitations.
There are real-world consequences to these errors. In the UK, an UberEats driver was dismissed when an AI verification system repeatedly failed to match his selfie with stored images. He sued for discrimination and won compensation, citing algorithmic bias.
Bias can emerge when models are trained on unrepresentative data, resulting in higher error rates for certain demographics. That’s why human review is still necessary to ensure fairness.
Who's Winning the Battle?
Right now, the tools to detect most deepfakes are still ahead—whether through trained analysts or advanced AI solutions. However, deepfake tech is evolving fast, and some fakes are already sophisticated enough to fool both people and machines.
The best defense is constant training and updating of AI systems using new fraud examples. Teams need to remain vigilant during ID verification and feed their models with real-world data from suspicious or failed attempts.
That said, many AI-generated fakes still fall short in dynamic scenarios. Deepfakes often fail to reproduce natural shadows or backgrounds accurately. Fraudulent IDs typically lack holograms and other dynamic security elements that change with motion or light. And because most deepfake training data is based on static photos, it struggles with real-time 3D video sessions where head movement is required.
Modern verification systems can leverage these shortcomings. For instance, requiring users to tilt or rotate their ID document during a liveness check makes it very hard for fake documents to pass. Physical security features are nearly impossible to replicate convincingly in such conditions.
Another strong defense is controlling the video capture source. Native mobile apps, for instance, prevent external video tampering—adding another layer of security. Plus, layering in other forms of verification (like address checks or database matches) strengthens the process further.
While fraudsters are constantly evolving their methods, today’s AI-assisted verification still has the upper hand—so long as businesses remain proactive.
Building a More Secure Identity Verification Process
Adopting advanced tools is essential for companies that want to secure and streamline identity checks. Robust solutions like Regula Document Reader SDK and Regula Face SDK can significantly reduce the risks posed by AI-generated fraud.
Regula Document Reader SDK examines document images for authenticity, confirms physical presence, and extracts necessary data. It compares documents against a vast database to catch forgeries.
Regula Face SDK performs real-time face recognition and detects presentation attacks with high-accuracy liveness detection and facial attribute checks.
These solutions offer both precision and compliance, helping businesses fight AI-powered threats while delivering a smooth user experience.
