We’re not entirely sure that we understand all of this but Fujitsu have found a way to take biometric data, which is used to securely access systems, and turn it into cryptographic keys.
Basically, it turns the configuration of veins in a user’s hand into a crypto key which is massively more secure when used to access a network or system. They’ve included error compensation algorithms and this implementation could be used to securely access cloud-based systems using biometric data.
At present, biometrics are used mostly on local machines but that has been changing of late. Fujitsu’s development could speed up that process. As for when we’ll see it? A commercial version could be on the market as soon as 2017 – the company are speeding up the decryption time at the moment.
