Yes. They explained all the innovative magic of Apple's fingerprint sensor was better image resolution. So all they had to do was improving that on their end too. I imagine the body changes everywhere over time, so this resolution game has a hard limit. A fingerprint is the worst choice of biometric data, as people leave them everywhere...
- abritinthebay 9y agoPeople don't leave perfect moldae prints everywhere. AFAIK CCC never had a proof of concept of a real world usage of this. They needed access the original finger. That isn't to say it's not possible but it is a pretty major asterisk.
- mae9tvw5 9y agoThey have done it with a fingerprint left on the device screen later on, if i remember correctly.
- abritinthebay 9y agoIf I remember rightly that was a print applied to scanner glass, much less successful, and required absolutely perfect print transfer. Which, imo, isn't much different conditions tbh (i.e. not representative of the real world)
- 7542468964 9y agoRead the original ccc article or watch the video! They got the print off the phone itself. Only restriction is a high resolution scanner OR camera to capture it.
- kuschku 9y agoThey did it also with a simple press photo of a politician. There's no need to get a perfect copy.
- nobodyorother 9y agoDidn't some group pull a politician's finger print off his dinner glass and then include it as an insert with all the issues of some magazine? Can't find the reference right now, but somebody's gotta remember this, it was when the UK was considering using biometric data as IDs.
- lorenzhs 9y agoThat was CCC in 2008. To underscore the inherent problems of biometric authentication, they pulled Wolfgang Schäuble's fingerprints of a dinner glass and published it in their magazine. That issue also included a ready-to-use replica. Schäuble was Germany's interior minister at the time and a strong proponent of biometric data in passports and increased surveillance. https://www.ccc.de/updates/2008/schaubles-finger https://www.ccc.de/updates/2008/schaubles-finger (in German)
