ODDS 2024 – Innovate to Thrive

Nestled among seven hills overlooking the Tagus River, Portugal’s vibrant capital city Lisbon played host to the Optical & Digital Document Security™ (ODDS) 2024 conference (8-10 April). As well as providing a welcoming space for the ID, currency and secure document technical community to meet and share ideas, the conference once again proved to be the venue of choice for announcing several new security technologies.

Laying the groundwork

As with previous editions of ODDS, the seminars that preceded the two-day conference invited experts in the field to lead in-depth analyses of topical interest to the document security industry.
In the morning session, Franziska Granc and Arno Fiedler from Nimbus Technologies reviewed the work of the EU in setting out rules and structures for a European Digital Identity Wallet. The provision of the wallet will be mandatory for all member states and its acceptance as a means of identification and authorisation will become obligatory for all large online platforms such as Google, Amazon and Meta.

The afternoon seminar, on the potential impacts of AI and quantum computing (QC) was divided into three parts, hosted in turn by seminar leader Prof Dr Volker Lohweg (inIT-Institute Industrial IT) who gave a thought provoking overview of AI, Dr Anke Ginter (Bundesdruckerei, Germany) who explained the concepts behind QC, and Ian Lancaster (ODDS Programme Director) who pulled the threads together to consider the implications for optical and digital document security.

Access to the presentations is limited to ODDS 2024 attendees, please use the password which was provided by the [email protected]

The ODDS seminars were very worthwhile, and were money well spent. They also laid the groundwork for the remainder of the conference.

AI and QC

Carrying over to the first day of the conference presentations, the risks posed by AI was also the theme explored in Jordan Brough’s (Homeland Security Investigations Forensic Laboratory, US) keynote address ‘AI-Driven Counterfeits: The Possibilities and How to Fight Them’. In his highly entertaining and informative address, Jordan explored how AI could be used to create convincing fakes and described strategies government issuers should be using to fortify their credentials against AI-enabled fraud.
Anke Ginter followed up on her seminar presentation in her paper ‘Think Quantum – a New Perspective on Security’, giving insights into the importance of combining different quantum technologies on analogue and digital security products. Alexander Winnen (Veridos, Germany) picked up on this train of thought in his paper ‘Protecting IDs in the Quantum Computing Era’ where he explained the concrete steps that need to be taken to secure travel documents and their infrastructure.
Zbigniew Sagan (AT&T, France) in his paper ‘Artefactometry by Artificial Intelligence for Marked Objects’ set out how physical objects can be distinguished using characteristics similar to human biometrics. Through a deep learning-based method, the process can be easily adapted to diverse objects and manufacturing processes requiring only a few hundred samples for effective AI training.
It’s a brave person that tries to predict ‘What Will Passports Look Like in 20 years?’, but that is exactly what Renaud Laffont-Leenhart attempted to do in his paper exploring how AI will change the way we design and verify documents, and questioning whether documents will still be designed primarily for human inspection.
The panel discussion on Day 2 of the conference was also on the theme of ID document security in the face of AI and QC. Ian Lancaster did a good job of moderating the discussions which stimulated a lot of open debate amongst the panellists and audience.

Digital security

Whilst AI and QC received a fair amount of coverage, they were not the only topics to be explored at the conference.

Alan Hodgson’s (Alan Hodgson Consulting) paper described a project that is running in the UK which examines the potential for a Digital Product Passport to inadvertently disclose personal ID information. The premise explored was that seemingly ‘product only’ data can reveal personal data about users.  

In his paper ‘Stealth Spectral Landmarks for Complex Objects’ Authentication’, Marc Pic (AT&T, France) described a new approach in object identification using a frequency-prepared signal. This allows integration of spectral landmarks into an object’s substructure, which have proved useful for text acquisition on curved surfaces and 3D digitisation.

The topic of ‘Secure and Trusted Identification Interactions in the Digital Sphere’ was tackled by Jérémy Chmiela (IDEMIA, France), drawing on key learnings from digital ID programmes deployed in the US, Colombia and Morocco. Hendrik Graupner (Bundesdruckerei) presented a novel biometric trait which measures visual self-recognition as an in-brain identity validation mechanism.

Jorge Carvalho (Austrian State Printing House, OeSD) gave some insights into the benefits and challenges of implementing ID wallet applications in his paper ‘Enabling Citizen Protection with Seamless and Secure Digital Identity Wallets’.

Optical security

The editor of Reconnaissance publication ID & Secure Document News, Francis Tuffy, used historical and current news sources to review the development of optically variable devices (OVDs) and consider their future as a means of protecting documents. His paper paid particular attention to the diminishing market for physical visas and the growing opportunities from smartphone authentication.

Sajan Ambadiyil (Centre for Development of Imaging Technology, India) conveyed the story of the implementation of hologram-embedded security tax labels over the previous 20 years and their current transition to taggant-based holographic track and trace labels. Jérémy Malinge (Crime Science Technology, France), in his paper ‘An OVD Secured by Design’, gave details of a security feature viewable with the naked eye, classical UV light and a simple LED light of a smartphone, to gather all the verification modes traditionally used in the field of document security.

With so many types of optical features currently available for document protection, Yit-Sun Leung Ki’s (Security Identity Alliance) paper ‘Modern Optical Features for ID Documents – a Review’ was a timely reminder that there are actually only a very small number of light-matter phenomena and that from these you can make a succinct but complete review of Level 1 features for ID documentation.

‘Colour-Tuneable Photonic Crystals’ was the subject of Keeyeon Kim’s (NanoBrick, South Korea) presentation demonstrating the application of advanced nano-security technologies capable of dynamically altering reflective colours by adjusting the photonic crystal structure in response to an external magnetic or electric field.

Steve Sun (Wuhan Huagong Image Technology, China) took a 180-degree view of OVD design in his paper ‘Special Information Encryption for Optical Lithography Technology’. Steve and his team have established a model based on the intended optical effect from which an optical microstructure is simulated and engraved onto photosensitive material.  

To round off the optical security part of the conference, Daniel Parrat and Erik Egemalm (Rolling Optics, Sweden) explored micro-optics in the 4th dimension, Dr Dong Yang (ZSST – CBPM, China) presented security features based on light-field shaping using freeform microstructures and Leehwan Hwang (Kwangwoon University, South Korea) explored a computer-generated holography solution to print document protection.

The place to innovate

ODDS has gained a reputation as THE technical conference for physical, digital and virtual document security, and is proud of its status as the birthplace of nascent techniques that go on to reach commercial maturity.

As if to endorse this, Sebastian Mader (OVD Kinegram, Switzerland) started his paper ‘Utilising Two-Colour Colourshifts for Highest Security’ by cataloguing the various colourshift innovations that had been launched at ODDS, before leading into an exploration of his own work on foil-based features possessing a two-colour colourshift effect.

Scott Haubrich and Aldric Molina (SICPA, Switzerland), in their paper ‘Development of Innovative Machine-Readable Luminescent Features’, presented the next chapter in SICPA’s luminescent technologies. He laid out a set of innovative machine-readable security features using new emerging materials such as quantum dots, metal-clusters, and halide perovskites that exhibit highly tuneable spectral properties.

With a title like ‘Brilliantly Innovative: a New Security Feature Using Micro-Optical Freeform Elements’, you had better have something impressive to present. And Dr Martin Egginger (Hueck Folien, Austria) didn’t disappoint. His paper described a new security feature based on freeform micromirrors that enable high visibility in any lighting and from any angle which, when combined with thin film coatings, provide colourful moving effects.

To shake things up a bit, Michael Natan (Diametryx, US) presented a series of novel, ink-based security features comprising micron-scale particles that change colour in response to shaking, tilting, or magnetic fields. The features can create all known colours and enable rapid simple unambiguous readout by the general public.

Toppan (Japan) colleagues Keitaro Sugihara and Yoshiyuki Mizuguchi presented a new optical design that generates achromatic effects at specific angles through a combination of periodic and non-periodic structures.

Protecting ID and secure documents

This round-up of other papers from the conference, demonstrates the breadth of technologies for  ID and document protection that got an airing at ODDS 2024.

Cryptographic security as used in mobile IDs was the subject of Frank Schmalz’s (Veridos) paper ‘Security Challenges of Mobile IDs’, in which he looked at how some smartphone apps with ‘Mobile-ID’ functionality attempt to address this with ‘special effects’. Tom Mitchell (Luminescence Sun Chemical Security, UK) took us behind the scenes to look at multilayered functional barcodes for security documents, and Roger Bollström (MOZAIQ, Switzerland) discussed how protection can be achieved through personalised ‘watermark-like’ features.

On behalf of the team, I would like to show our appreciation about how the successful event was organised and we really enjoyed every presentation.

Changing of the guard

In his closing remarks, Ian Lancaster went to great lengths to thank the sponsors, tabletop exhibitors, conference organisers and, of course, participants. He also acknowledged the work of the members of the conference committee in ensuring the high quality of the papers and the authors for making them so.

This was the last ODDS conference that Ian Lancaster will lead. He has been involved with this conference series from the first van Renesse event in 1996, leading the evolution of the conference through several iterations to its current format.

Ian, who has been granted the title of Chairman Emeritus, closed the conference by introducing Francis Tuffy as the new Programme Director and wishing him all the best for the next ODDS, to be held in Warsaw, Poland in autumn 2025.

ODDS was very good because the conference showed clearly that digital technologies are the game changers in the community. Therefore, DDS is necessary and it will grow.

inIT-Institute Industrial IT

It is a great event, absolutely necessary, came at the right time. A good mixture of technical and general topics.


This conference filled the gap between physical and digital security. The agenda was more than excellent.

ANY Security Printing

An interesting and thought provoking conference, bringing together many technologies and perspective, united by the common theme of digital security. I think the conference fills a gap, perhaps many gaps, and I look forward to the next.

Luminescence SunChemical Security

A very good start with some technical and policies perspective are discussed in the conference. An eye opener and a must for any security printing industry players to welcome the future of the industry.

M.J.M. International

Very well organised/managed conference. The level of expertise in the group of presenters and audience is of high standard. I greatly benefited from my attendance. Very friendly and supportive staff.

09:00 – 12:30 Seminar – European Wonder Wallet: Essential Information for ID and Document Providers

Seminar Leader, Franziska Granc – Senior Project Manager at Nimbus Technologieberatung GmbH and Arno Fiedler – Managing Director of Nimbus – and member of the European Technical Committee (TC) for Electronic Signatures and Infrastructures (ESI)

While technological means are developing rapidly and new technologies can already create solutions for all sorts of document and credentials issuing, storing and presenting, regulation need to catch up to it. A steady regulatory framework is needed to secure data protection and privacy and to avoid fraud and manipulation. Accordingly, the EU is working towards a framework which is the first of its kind, setting out rules and structures for a European Digital Identity Wallet. The provision of the wallet will be mandatory for all member states and its acceptance as a means of identification, authentication, and authorisation obligatory for all Large Online Platforms (Google, Amazon, Meta). Backed-up by other European regulations such as the Digital Services Act and the Digital Market Acts, as well as upcoming stricter rules for organisations in the critical infrastructure defined by the Network and Information Security Directive (NIS II), Europe is facing big changes that will fundamentally transform the digital sphere.

As the EU thus leads the way towards a solution for secure digital identities and identity-related documents, this seminar will explain the main goals, potential and challenges of the revised eIDAS regulation and how this relates to the Digital Wallet. We will give an overview of these inter-related  regulations that support eIDAS and strengthen Europe’s digital sovereignty but which might also raise conflicts between EU and national law.

Join us to learn more about these far-reaching developments that, if implemented correctly, could be a worldwide pioneering solution for secure digital identities and identity-related documents. If you are involved in issuing, storing, and verifying identity information you need to understand these EU moves and how they will affect your organisation.

13:30 – 17:00 Seminar – AI and Quantum: Where Now for Document Security?

Seminar Leader, Prof. Dr. Volker Lohweg – inIT-Institute Industrial IT, Dr Anke Ginter – Bundesdruckerei GmbH & Ian Lancaster – ODDS Programme Director

This seminar explains the current developments in two areas of computing which could have a significant impact on identity and transaction security: artificial intelligence and quantum computing.

The seminar is in three parts: Dr Volker Lohweg will give an overview of AI; Dr Anke Ginter will then explain quantum computing, and Ian Lancaster will pull this together and consider the implications for optical and digital document security.

An Introduction to Artificial Intelligence

Artificial intelligence is much talked about and read about, but what is actually behind it? What types of AI are there and what applications are possible?

Apart from ethical and cultural considerations, there are numerous challenges and hurdles in the use of AI. It is necessary to integrate AI methods into existing systems and structures and, in some cases, to reorganise responsibilities and processes.

In this short survey of AI, Volker will explain the differences between human intelligence and artificial intelligence, then take a look at the history and consider what AI can do today. He will also explain how such systems are trained and what impact this has on us in the application. He will conclude with a discussion of examples from image processing and the design of documents, pointing out the possibilities for use, but also explain the current dangers, such as deep fakes, before glancing at the future prospects for AI

Quantum computing and its impact on Security

Increasing performance and algorithmic realizations of Quantum computing devices bring the quantum threat closer to current ID systems and documents. Even if experts disagree when and how this will be manifested, the effects of such threat are far-reaching. Moreover, the development of quantum computing demonstrated how fast disruptive technologies can come up and question security considerations. This is the reason why reactions and adaptions should be done as soon as possible. Post-quantum security and crypto agility can be viewed as the first step on the way to a secure quantum era.

In this seminar, we will give an overview of the current state of quantum computing devices to get a deeper understanding of the technology. Furthermore, we illustrate how quantum computing, quantum communication and security stick together and should be regarded as a unit to see the whole picture and react appropriately.

The Implications…

So what does this mean for our field of document security? What are the implications for our digital or virtual identities and our online transactions, whether checking our bank account or buying from Amazon? How does this impact the physical documents we carry: our IDs and banknotes? Do they need to change, adapt, interact more with the online world?

Ian Lancaster will lead this part of the seminar, pulling together what we have learned and facilitating a discussion of what it means for this field.

Seminar Leaders:

Prof. Dr. Volker Lohweg is the head of the research group “Discrete Systems” and Director of the inIT-Institute Industrial IT. The research group’s working area is dedicated to Cognitive Systems in automation especially Information Fusion and Optical Document Security, including banknote inspection and authentication. He is active in SPIE and IEEE as a reviewer in the field of image processing and data analysis. His interests are sensory conflict modeling and Multi-Scale signal analysis in the context of optical and digital document security.

Anke Ginter is a Senior Innovations Developer at Bundesdruckerei GmbH in Germany. She works on quantum computing and quantum communication systems with special focus on usability and security.
