Optical Technologies Shine in ODDS 2025 Programme
8 Aug 2025 | Press Release
The programme for the 2025 Optical & Digital Document Security™ (ODDS) conference, which takes place 15 –17 September in Warsaw and is supported by the International Optical Technologies Association (IOTA), has now been finalised, reaffirming its position as the technical forum for physical, digital, and virtual document security.
With eight themed sessions curated by a globally respected technical committee, the agenda spans cutting-edge research and field-tested applications, underscoring the relevance of optical science around document security.
A notable feature of this year’s conference is the strengthened focus on optical technologies as engines of innovation. These systems—ranging from diffractive structures and nanophotonic devices to colour-shifting materials and deep-subwavelength OVDs—form the backbone of modern document authentication, particularly as the threat landscape shifts with AI and quantum computing.
Day one is dedicated to visual security, a showcase of advanced optical engineering. Highlights include RollingStar® Venus: dynamic and precise colouration by Louisenthal, innovative machine-readable infrared absorbing features (SICPA), 3D light-field imaging by ZSST (CBPM Group), stable colour 3D OVDs by Toppan, IN Groupe’s zero-order diffractive structures, and plasmonic nanostructures. The integration of optical and digital technologies is reflected in presentations on optically variable inks, nanoparticle effects, and new digital security features.
The day concludes with the launch of IOTA’s ‘First Excellence in Optical Technologies Awards’. This new awards programme offers a global platform for outstanding technical achievements in optical engineering. By highlighting innovative concepts and manufacturing breakthroughs, the IOTA Awards emphasise that the optical sector remains a vibrant hub of innovation.
Day two explores digital and hybrid threats, from AI-driven adversarial attacks to quantum vulnerability mitigation. Even here, optical technologies appear in new roles—supporting physical unclonable functions (PUFs) and enhancing the robustness of hybrid digital-physical credentials. Presentations include deep sub-wavelength plasmonic OVDs by Authentix, the use of AI for enhanced artefact verification, barcode authentication, and discussions by the editorial team behind the upcoming 4th edition of Optical Document Security, which itself reflects an expanded technical horizon, including smartphone verification.
Pre-conference seminars provide essential context, addressing structural concerns such as eurozone counterfeiting patterns, the regulatory response to document fraud, the architecture underpinning the EU’s digital identity rollout and ‘What Next for Optically Variable Features’ hosted by IOTA. The IOTA seminar will address current technological advances, shifting security demands, and evolving threats that influence the development of optical technology. Through expert insights and real-life examples, the session will highlight how optical technologies must adapt to remain effective in both physical and digital authentication.
As the identity security sector evolves, ODDS 2025 makes a clear statement: optical technologies are not confined to a pre-digital age—they are the foundation of trust, visibility, and verification in the phygital era.
