dare il dito e’ un gesto attivo.
essere inquadrato e’ un gesto passivo.

vi ricordate la vicenda di sblocco del telefono da parte della polizia ? non sara’ piu’ un problema.
(ma nemmeno per il tuo compagno/compagna, mentre dormi…)

ma a parte questi risvolti positivi/negativi, in genere, usare la biometria per autenticare, come ho sempre scritto, non è una grande idea.

Scrive Alberto Cammozzo: Ci sono approcci di spoofing (falsificazione dell’identità) molto raffinati che consentono l’impersonamento di chiunque stampando degli occhiali ad-hoc.

Hackers Trick Facial-Recognition Logins With Photos From Facebook (What Else?)

Earlier this month at the Usenix security conference, security and computer vision specialists from the University of North Carolina presented a system that uses digital 3-D facial models based on publicly available photos and displayed with mobile virtual reality technology to defeat facial recognition systems. A VR-style face, rendered in three dimensions, gives the motion and depth cues that a security system is generally checking for. The researchers used a VR system shown on a smartphone’s screen for its accessibility and portability.

Their attack, which successfully spoofed four of the five systems they tried, is a reminder of the downside to authenticating your identity with biometrics. By and large your bodily features remain constant, so if your biometric data is compromised or publicly available, it’s at risk of being recorded and exploited. Faces plastered across the web on social media are especially vulnerable—look no further than the wealth of facial biometric data literally called Facebook.
