bluCognition’s FraudLen’s product instantly analyzes documents for document tampering


Real time Document Tampering Detection

  • AI-powered document fraud detection capability
  • Uncover fraudulent documents and prevent first-party fraud
  • X-ray vision capability to recover the original document
  • Metadata analysis and file forensics to look for evidence of document tampering
  • Our algorithms are informed by over 10M+ documents across multiple financial institutions, various document types, and commonly used PDF editors

Documents are scored based on the findings of the document assessment and are categorized by high, medium, low, and no fraud risk.

FraudLens will show you the document you uploaded vs the recovered document with highlights to any sections that have been modified
