A fraud detection solution using AI for a modern KYB business verification process
OCR alone isn't enough. We analyze the full context of the document (format, layout, structure), how it was created (checking quality inconsistency, inserted or manipulated elements, etc.), how it was sent (checking device fingerprinting data or behavioral signals for example), as well as checking for serial fraud (checking for repetitions in background, image characteristics, lighting conditions, lens geometry, etc.).
In order to detect if a document has been tampered with, we use a layered approach (aka interlocking layers of detectors that are incredibly difficult to evade). Our AI analyzes every document over 500 ways to detect any sign of tampering, farming, or reuse.

Do you have any questions?
What documents can be checked for fraud?
Resistant AI is document agnostic. That means it works with any document you use, from anywhere. Here's a non-exhaustive list: Tax forms, bank statements, pay stubs, account statements, IDs, invoices, paystubs, utility bills, tax returns, driver's licenses, social security cards, birth certificates, marriage certificates, college transcripts, university diploma, W-2 forms, 1040 forms, etc.
We even detect AI generated documents that would not be identified by manual human review.
What document formats do you support?
Resistant AI works with all PDF and image formats. Different formats have different risk profiles, and we can help you set up a policy that matches your risk appetite.
In what languages can Resistant AI analyze documents?
Resistant AI analyzes documents in any language. In fact, we don't read the content of the documents to catch fraud—we analyze the whole context of how the document is made instead. Simply put, we look at how the words are written, not what they say.
How does Resistant AI scan documents for fraud?
We analyze every document over 500 ways for signs of tampering or fraud to ensure high precision on our verdicts. That includes internal structures, image inconsistencies, fonts in use, metadata analysis, visual similarities, etc. We then compare all incoming documents to find document reuse, template farms, and high-scale fraud attempts.
How long does it take for Resistant AI to review a document?
It takes less than 20 seconds on average for you to get your verdict when analyzing a document for fraud with Resistant AI.
How can I know if a document is fraudulent?
We don't believe in risk scores: What do you do with a 68% vs an 82% document risk score?
Instead, Resistant AI gives you clear actionable verdicts:
- High Risk: this document is likely fraudulent and should be declined.
- Warning: this document is modified and should be reviewed.
- Normal: there’s nothing wrong with this document and can be accepted.
- Trusted: this document perfectly matches authentic ones.
How can I use Resistant AI?
You can either use Resistant AI manually by dropping documents in our web interface, or use our API integration to automate fraud detection at scale.
How serious is document fraud?
By analyzing millions of documents every month, we've found that 25% of documents show signs of tampering, and up to 2% of documents are based on reused or generated documents indicative of crowd-sourced first party fraud or organized crime rings.
Can I detect fraudulent or forged documents from applicants as part of a KYB process?
Yes. You can check all the documents required as part of the KYB process during your supplier or business customer onboarding flow. Our online fraud detection tool allows you to easily drag and drop your documents to spot forged documents, or automate your KYB process with our API.
How can I scan a large number of documents in order to detect potential document editing or manipulation?
With Resistant AI, you can verify documents submitted by your users on a large scale. We check millions of documents for our customers every month. The only thing you need to do is deploy our API to automate your fraud detection.
How can I validate the authenticity of a pay stub as part of an income verification process?
You can check a pay stub's authenticity by scanning the document with Resistant AI's fraud detection solution. Our system will tell you if the document has been modified or is fraudulent, and should therefore be declined.
