Samsung had closed its gap with apple when finally the South Korean giant had added the touch-based fingerprint sensor to the Galaxy S6 and the Galaxy S6 Edge.

However a report has emerged that claims that the fingerprint sensors that are used in Samsung or Android smartphones are not as secure as TouchID fingerprint sensor used in the iPhones.

This research has been carried out by Yulong Zhang & Tao Wei and was presented at the Black Hat USA 2015 conference in Las Vegas earlier this week.

Here new ways to attack Android devices and steal fingerprints were demonstrated. Interesting thing is that these threats are confirmed mostly to Android phones including Samsung, Huawei and HTC.

Four attacking methods were shown at the conference and out of these four the fingerprint sensor spying attack, is able to steal fingerprints on a large scale.

This attack was confirmed on the Samsung Galaxy S5 and HTC’s One Max. These sensors are easy to hack as they are guarded by ‘system’ privilege instead of ‘root’.

The researchers also did not mention that which Android smartphone maker has better security than then the other but they did mention that the security system on Apple’s iPhones is much secure.

This they explained is because iPhones encrypt the data from the fingerprint sensor. The researchers have advised that users should on a regular basis update their devices and install apps from reliable sources.

They also advised that users should not root their devices. Even Samsung itself has asked its Galaxy S6 and Galaxy S6 Edge users from not rooting their devices as then Samsung Pay won’t work on their devices.
