Document Liveness

Overview​

Document Liveness is Verifik's advanced fraud detection system that ensures the authenticity of identity documents by detecting various types of document manipulation and presentation attacks. It uses cutting-edge AI technology to identify fake, manipulated, or fraudulent documents in real-time, providing comprehensive protection against document fraud.

How Document Liveness Works​

Document Liveness analyzes uploaded document images through multiple specialized detection pipelines, each designed to identify specific types of fraud attempts. The system processes documents through AI-powered algorithms that examine various aspects of document authenticity, from screen replay attacks to sophisticated digital manipulations.

What Document Liveness Detects​

Document Liveness provides comprehensive fraud detection across four critical areas of document security:

Screen Replay Detection​

  • Identifies documents displayed on screens or monitors
  • Detects attempts to present digital copies instead of physical documents
  • Recognizes screen glare, pixelation, and digital display artifacts
  • Prevents fraud from photos of documents on devices

Printed Copy Detection​

  • Identifies photocopied or printed versions of documents
  • Detects paper texture differences and print quality issues
  • Recognizes scanning artifacts and reproduction patterns
  • Prevents fraud from high-quality document reproductions

Portrait Substitution Detection​

  • Identifies when photos on documents have been replaced
  • Detects inconsistencies in photo placement and quality
  • Recognizes tampering and manipulation attempts
  • Prevents fraud from document photo replacement

Digital Manipulation Detection​

  • Identifies digitally altered or edited documents
  • Detects inconsistencies in document structure and formatting
  • Recognizes artificial elements and manipulation artifacts
  • Prevents fraud from sophisticated digital document fraud
