I ricercatori di sicurezza della piattaforma di scambio di criptovalute Kraken hanno dimostrato un metodo semplice ed economico per creare un clone di un'impronta digitale a partire da una foto, utilizzando una normale stampante laser, colla da falegname e materiali di uso comune. \u00c8 stato segnalato che il calco ottenuto ha permesso di bypassare la protezione dell'autenticazione biometrica tramite impronta digitale, sbloccando i dispositivi degli investigatori, tra cui un tablet iPad, un laptop MacBook Pro e un portafoglio hardware per criptovalute. <\/p>\n

Le tecniche per ricreare impronte digitali sono note da tempo, ma generalmente richiedevano abilit\u00e0 speciali o attrezzature costose, come una stampante 3D. Il costo di creazione di un clone con il metodo proposto \u00e8 di circa 5 dollari. Nella prima fase, si utilizza uno smartphone normale per fotografare l'impronta lasciata su una qualsiasi superficie liscia, ad esempio, sullo schermo lucido di un laptop o uno smartphone. <\/p>\n

Successivamente, in qualsiasi programma di grafica, si esegue l'operazione di aumento del contrasto del pattern papilare, creando un negativo, ritagliando e convertendo l'immagine in formato bianco e nero. Dopo di che, l'immagine preparata viene stampata su una comune stampante laser, ma invece della carta si utilizza un foglio di acetato — una pellicola trasparente utilizzata per realizzare stencil, adesivi e schede. Durante il processo di stampa, il toner crea sul foglio di acetato delle scanalature testurizzate in rilievo che riproducono il pattern papilare. <\/p>\n

Nell'ultimo stadio, sulla pellicola viene applicato uno strato sottile di colla per legno, che una volta asciugato forma una sostanza elastica che riproduce un pattern papillare tridimensionale. Posizionando la pellicola ottenuta su un dito, \u00e8 stato possibile sbloccare la maggior parte dei sistemi di verifica biometrica delle impronte digitali testati.
