ODDS 2025 Conference

Registration is now open for the Optical & Digital Document Security™ (ODDS) conference, which will be held in Warsaw from 15-17 September 2025.

The ODDS technical committee has completed evaluating the submitted abstracts, confirming a strong line up of presentations. The programme again demonstrates why ODDS is the premier technical conference for security in physical, digital, and virtual documents.

In the optical segment of the programme, attendees will discover new research covering a full spectrum of optical security technologies, including deep sub-wavelength and plasmonic OVDs, holographic greyscales, zero-order structures, 3D light-field technology, and optically variable inks.

There will also be an update on progress made with publishing the new edition of ‘Optical Document Security’. This updated edition will provide essential scientific insights into optical deterrence, including a new section focusing on how smartphones are reshaping the analysis and verification of optical features.

The digital security track will highlight advances in artificial intelligence and machine learning, post-quantum cryptography, and copy protection patterns. Presentations will also delve into the growing ‘phygital’ space, where physical and digital security converge through QR codes, holographic markers, and hybrid systems.
