Modern Forgery
The arms race of authentication.
Forgers no longer just trace over a light box. The techniques have evolved.
Current Threats
- CNC Plotters: Computer-controlled pens that map the fluid dynamics of a human signature. Harder to spot than traditional autopens.
- Photo Emulsion Lifts: Lifting a genuine signature from an unimportant document and chemically transferring it to a high-value photo.
- Vintage Paper Sourcing: Using blank end-pages from 1800s books to defeat carbon dating on forged historical letters.
We rely on microscopic examination and provenance chains to defeat these methods.
