Touch ID

Samsung Galaxy S5 fingerprint swiper can also be faked out, but here's the difference with Touch ID...

As expected, the fingerprint swiper in the new Samsung Galaxy S5 is just as susceptible to spoofing by a fake fingerprint, just like Apple's Touch ID on the iPhone 5s, and pretty much every similar fingerprint sensor on the market. But it also looks like there are few things Apple did right that Samsung might want to look into incorporating in the future.

iOS 7 Activation Lock bypass discovered, protect yourself with Touch ID or Passcode

A bug has been found in iOS 7 that allows a an attacker with physical control over a lost or stolen iPhone to get around Activation Lock and gain access to the device. Unfortunately, the method for circumventing Activation Lock has been made public. However, the bypass process requires the attacker have access to an unlocked device, and be able to access the device after a reboot, so it can be thwarted by simply having a Passcode enabled (either by itself or as part of Touch ID).

Why Samsung's fingerprint sensor needs to face the same scrutiny as Apple's Touch ID

Last week the new Samsung Galaxy S5 was introduced and along with it, Samsung's take on the fingerprint identity sensor. Apple, of course, introduced Touch ID fingerprint identity scanner alongside the iPhone 5s back in September of 2013. From launch Touch ID received considerable scrutiny over its implementation and its implications from the media, from security groups, and from the government. So, roughly 3 nano-seconds after the Galaxy S5 was swiped on stage, Apple enthusiasts began wondering out loud about just when exactly that same scrutiny would hit Samsung. Some felt it won't and that that's unfair. Others felt it won't and that that's perfectly reasonable.
