(ORDO NEWS) — The largest supermarket chains have launched a pilot project in the UK using neural networks to recognize the age of buyers who purchase alcohol.
This is part of a program by the local Ministry of the Interior to make it easier to market related products.
Some supermarket chains Asda, Co-op and Morrisons are participating in the experiment. Similar technology is already being used in Aldi’s London store, which is equipped with automated checkout counters.
With the consent of the buyers, the smart camera will try to recognize their age when buying alcohol – the neural network was trained on the basis of anonymous faces.
If the system determines that the buyer is under 25 years old, you will need to show ID to the employee in the hall (while alcohol in the UK is available from 18 years old).
According to Robin Tombs, head of technology company Yoti, “Waiting for age verification at a self-checkout can sometimes be frustrating for shoppers.
Our age verification solution helps retailers like Asda comply with regulators around the world and keep up with user demands for fast and convenient services while maintaining people’s privacy.”
Yoti emphasizes that this is not about face recognition – there are no images of buyers in the database.
A neural network trained on more than 125,000 images of people from 6 to 60 years old, on average, learned to recognize age with an accuracy of 2.2 years, and when assessing people from 16 to 20 years old, with an accuracy of 1.5 years.
This system differs from those already tested before, for example, comparing the face of the buyer with the base of those who were seen in thefts or antisocial behavior.
