Diffusion-Based Authentication of Copy Detection Patterns: A Multimodal Framework with Printer Signature Conditioning

Key Points

• Improved authentication accuracy in copy detection patterns is achieved through diffusion-based techniques, showing new potential.
• Key metrics show significant enhancement in detection capability when integrating printer signature conditioning techniques.
• Observational analysis employs a multimodal framework to enhance traditional detection methods for copy authentication.
• Findings suggest that implementing these techniques could lead to stronger security protocols in document verification.
