Galaxy S5 fingerprint scanner hacked
Fake fingerprint used to unlock Samsung's new handset
Samsung's new Galaxy S5 smartphone's fingerprint sensor has been hacked, just four days after launch.
A group of security researchers in Germany was able to create a fake fingerprint and use it to unlock the handset.
The team from Security Research Labs (SRL) was able to create a fake print by taking a photo of fingerprint on the screen of the handset, and then creating a plastic duplicate. The fake print could then be swiped on the sensor to unlock the phone.
Apple's iPhone 5S was hacked using the same technique by the Chaos Computer Club last year.
The hack raised concerns about the security of the handset, particularly as Samsung has allowed third party apps to use fingerprint identification. The first such application, from PayPal, allows money transfers.
SRL also criticised the fact that the Samsung S5 doesn't lock after a set number of failed login attempts, but allows users to keep on swiping.
