Austria - 25 Euro AgNiob, Big Data, 2020

In its niobium core, the obverse of Big Data features a human eye that represents surveillance on the one hand and the biometric method of iris recognition on the other, while the silver outer ring is designed like a camera lens. Iris recognition means that we can all be recognised unequivocally. The reverse of the coin shows people under surveillance, which is recognisable from the 20:20 running time on the left edge of the outer silver ring. In the foreground of the niobium core, one of a number of human silhouettes is peppered with squares that symbolise the personal data collected about that person.
