App used by emergency services under scrutiny

Questions have been raised about a digital addressing system which divides the world up into three-by- three-metre squares to pinpoint someone’s location.What3Words (W3W) gives each square a unique three-word address, and the app is used by 100 UK emergency services.

But a security consultant found thousands of locations with similar words less than 1km (0.6 miles) apart.W3W acknowledged there were similarly labelled squares in close proximity, but said examples were rare.The issue appears to be how the system’s algorithm sorts where to put which three words, and in particular where it places words that are spelt differently but pronounced the same (homophones), similar sounding words, and plurals.
