The Four Letters Transforming Airport Security: IOAO. It is Ready. Is Your Airport Ready Too?

As the VP of Products at SeeTrue, I get asked often about the next big shift in security screening. My answer is always the same: the best use of a trained security officer is not reviewing thousands of clear bags. It is being sharp and ready for the one who is not.
A revolution is already underway at security checkpoints around the world. The technology is certified, proven, and operational. The question is no longer whether it works; it is whether your airport is ready to use it.

As travel volumes continue to break records, airports face pressure that cannot be solved by hiring alone. There simply are not enough trained security officers to manually inspect every bag at the speed modern terminals demand, and building new infrastructure takes years and many millions in investment. The answer is not more people staring at more screens. The answer is changing who looks at the screen, and when.

That shift has a name: IOAO. Image On Alarm Only. And it is available now.

What Is IOAO and How Does It Change the Operator’s Role?
In traditional screening, a human operator reviews every single X-ray image or CT scan that passes through the checkpoint. Hundreds per hour. Thousands per shift. The overwhelming majority are completely benign, and that is precisely the problem.

When we ask skilled professionals to search for a threat in an endless stream of harmless bags, we are not just occupying their time. We are eroding their edge. Attention degrades. Pattern recognition slows. The cognitive load of processing thousands of clear images makes it harder, not easier, to catch the one that actually matters.

IOAO flips this entirely. Advanced certified algorithms automatically screen every bag. A human operator is brought into action when the system detects a potential threat or anomaly. The operator becomes a resolver – alert, focused, and ready – precisely because they are no longer worn down by constant noise.

Can AI Really Be Trusted to Screen Bags Without a Human Reviewing Every Image?
I want to be direct about something: this only works if the underlying technology earns it.
IOAO is not a concept you can implement with a mediocre detection system. If the algorithm flags every third bag, you have not reduced operator burden; you have added friction and eroded trust in the system. For IOAO to deliver on its promise, you need algorithms that achieve exceptional detection rates with an extremely low false alarm rate. The certification threshold is deliberately demanding, and it should be. The bar exists because the stakes do.

In my experience, this is where the industry is rapidly separating into two groups: vendors who talk about AI-assisted screening, and vendors whose algorithms are certified to operate at the level IOAO actually requires. At SeeTrue, achieving that certification was among the most rigorous processes we have gone through, not because we sought a credential, but because we knew the technology had to be worthy of the responsibility.

How Does IOAO Actually Improve Throughput and Security at the Same Time?
The operational impact is tangible. Screening is faster because the algorithm clears safe bags in real time without waiting for a human to confirm the obvious. Officers are focused on where their judgment actually matters. Fatigue drops. Security improves.

I want to clarify a point that often comes up in these discussions, especially given that the second “O” can be slightly confusing. IOAO does not mean handing everything over to the algorithms. A percentage of bags are still reviewed at random, preserving accountability and keeping operators alerted. We are not taking the human out of the loop; we are putting them at the center of where it counts.

For passengers, the experience changes too. The line does not stall. The process is faster, and a faster process is, in the truest sense, a better passenger experience.

IOAO Is Not the Future Standard. It Is the Current One.
The case for IOAO is not theoretical. It is operational, measurable, and already proving itself at checkpoints around the world. Certified algorithms are running today. Throughput is improving today. Officers are working smarter today.

Every bag the algorithm clears is not an absence of work; it is the result of it. A precise, high-confidence decision made in real time, at scale, without fatigue. The system is not waiting. It is working. Continuously, accurately, and in service of the officers standing beside it. That frees officers for the moment that genuinely requires human judgment. When that moment comes, they will be sharp, focused, and ready.

The technology is here. The certification exists. The results are visible. The only question left is which airports will move first and which will spend another year asking whether they should.
