Biometrics are not secrets (it must be assumed that attackers always possess all biometric data), but they can nevertheless be a good form of authentication when combined with situational awareness. If you try to use one of these hot glued fingerprints in front of a security guard, it isn't going to go well for you.
At the moment, humans are still necessary for situational awareness, but probably machines can get there pretty soon. A phone, for example, that monitors its surroundings continuously and has enough intelligence to reliably distinguish normal access by its owner from duress or the presentation of fake biometrics seems like it's within reach of current technology (though it doesn't actually exist).
- capitainenemo 5y agoYou think the typical security guard would notice a print if it was glued on the finger? At workplaces I've worked at in the past they weren't watching the flow of traffic through the gate all that carefully...
- joenathanone 5y agoAdditionally a little social engineering would get right past an attentive guard, just strike up a little small talk to distract their attention.
- acdha 5y agoI think this depends on how well they do liveness tests: it's expensive to have guards checking everyone's hands (but certainly not prohibitively so if you have that level of threat) but it'd be a lot cheaper if your sensors are fairly good at raising an alarm to attract scrutiny.
