Research projects funded by Horizon Europe are required to specify the Technology Readiness Level (TRL) of their outputs \u2014 from TRL 1 (basic principles observed) through to TRL 9 (system proven in operational environment). Most security research projects aim to reach TRL 6 or 7 by the end of their funding period. But what does TRL 7 actually mean, and why is the journey from TRL 5 to TRL 7 so hard?<\/p>\n\n\n\n

The TRL scale<\/h2>\n\n\n\n

TRL 1\u20133 covers basic and applied research \u2014 algorithms demonstrated in the laboratory on curated datasets. TRL 4\u20135 represents technology validated in a relevant environment \u2014 systems working on real data in controlled conditions. TRL 6 means technology demonstrated in a relevant environment \u2014 prototype tested in conditions approximating operational reality. TRL 7 means a system prototype demonstrated in an operational environment \u2014 working alongside real users at a real border crossing. TRL 8\u20139 represents a system that is complete and operational.<\/p>\n\n\n\n

Why the gap is the hard part<\/h2>\n\n\n\n

Laboratory performance and operational performance are not the same thing. An algorithm that achieves state-of-the-art error rates on a benchmark dataset faces a very different challenge when deployed at a real border. The operational environment introduces variability that benchmarks cannot capture: inconsistent lighting, varying camera angles, travellers who are tired or distracted, documents that are worn or partially obscured, network latency, and the enormous diversity of nationalities and document types at a busy international crossing.<\/p>\n\n\n\n

The role of field tests<\/h2>\n\n\n\n

Field tests are the mechanism by which TRL 7 is achieved. They place a working prototype in a real operational environment and evaluate it against real traffic, with real end users, over a sustained period. The EINSTEIN project is conducting field tests at multiple sites \u2014 including the Promachonas-Kulata land border crossing and a port of entry in Southampton \u2014 providing the performance data needed to make the case for operational deployment.<\/p>\n\n\n\n
