Claimed Safe, Fingerprint Technology Turns Vulnerable Hacker

Almost all flagship smartphone is equipped with advanced features fingerprint scanner. The vendor claims that the biometric sensor improves the user experience and security of mobile devices. But is it true?

The proof, capacitive scanner older models is hard to recognize fingerprints were wet, and in most cases often do not work on the first attempt.

So, if your hands sweat during the summer or after exercise, your smartphone will most likely not work because it does not recognize your fingerprint.

Kaspersky Lab says that the scars, scratches, and other skin defects also lowers the quality of the scan. In addition, there are still many sensors that can not distinguish between a genuine finger by finger prints, and this is a very big gap in terms of security.

Some of these issues may be resolved when Qualcomm launches ultrasonic sensor, which uses ultrasound to scan a 3D image of a finger.

The sensor will not be fooled by the printout of the finger. In addition, the new ultrasonic sensor will still work even if your fingers are dirty or wet. Yet another threat is still there.

The new technology is always vulnerable because of relatively new. Not enough just to bring the latest innovations, new technology should be implemented in a safe manner because not all vendors are able to do that.

And even if they were able to overcome these problems, they certainly would not do for one version. For additional information, in August 2015, a new way to steal a fingerprint found remotely and on a large scale.

In addition, most smartphones have a sensor that is not encrypted, allowing malware to get a direct image of a fingerprint scanner. Interestingly, Apple’s smartphone is quite safe, since they encrypt the fingerprint data from the scanner.

Some vendors there also are using ARM TrustZone technology to protect the data on their devices. This technology works with fingerprint images that are in the “world” special virtual, which can not be accessed by the main OS.

As a result, important data (such as fingerprints) can not be leaked and used by third party applications. Unfortunately, depending on the model of implementation, this technology can also be flawed.

This year, the researchers show how easy it is to steal a fingerprint from a distance, even without face-to-face contact. Hackers can do so simply by photographing the finger of the victim.

SLR camera with a good zoom lens or even a magazine photo printed in high resolution is sufficient. For information, the same method can also be used to fabricate the iris.
