I ricercatori di sicurezza della piattaforma di scambio di criptovalute Kraken hanno dimostrato un modo semplice ed economico per creare un clone di un'impronta digitale da una foto utilizzando una normale stampante laser, colla da falegname e materiali di uso quotidiano. \u00c8 stato notato che il calco ottenuto ha consentito di bypassare la protezione dell'autenticazione biometrica tramite impronta digitale e di sbloccare il tablet iPad, il laptop MacBook Pro e il wallet hardware di criptovalute posseduti dai ricercatori. <\/p>\n

Le tecniche per ricreare impronte digitali sono note da tempo, ma generalmente richiedevano competenze speciali o la presenza di attrezzature costose, come una stampante 3D. Il costo per creare un clone con il metodo proposto si aggira intorno ai 5 dollari. Nella prima fase, un normale smartphone fotografa l'impronta lasciata su una qualsiasi superficie liscia, ad esempio su uno schermo lucido o sulla custodia di un laptop o smartphone. <\/p>\n

Successivamente, in qualsiasi editor grafico, si esegue l'operazione di aumento del contrasto del pattern papillare, creazione di un negativo, ritaglio e conversione dell'immagine in formato in bianco e nero. Dopo di che, l'immagine preparata viene stampata su una stampante laser standard, ma invece della carta si utilizza una pellicola di acetato \u2014 un foglio trasparente utilizzato per la creazione di stencil, etichette e schede. Durante il processo di stampa, il toner forma sulla pellicola di acetato delle scanalature texture sporgenti che ripetono il pattern papillare. <\/p>\n

Nell'ultima fase, sulla pellicola viene applicato uno strato sottile di colla da falegname, che dopo asciugatura forma una sostanza elastica che riproduce il volume del motivo papilare. Posizionando la pellicola ottenuta su un dito \u00e8 stato possibile sbloccare la maggior parte dei sistemi di verifica biometrica tramite impronta digitale testati.
