How to Bypass or Hack iPhone 5s Touch ID Fingerprint Sensor

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

These hackers showed how “easy” it is for them to access the iPhone 5s using some tools you can find at your home or local hardware store.


It was just about a week since the iPhone 5s was launched and hackers have been trying to proof that the iPhone 5s Touch ID fingerprint scanner is not as secure as what Apple claims. This group of hackers from Germany is called Chaos Computer Club.

To summarize the method they used, basically they took a high resolution photo of the original user’s fingerprint, printing it on a transparent sheet with a thick toner setting, and then filling it in with pink latex milk. You can watch how it’s done below:

Details of the process above is explained on ZDnet’s website:

“The method follows the steps outlined in this how-to with materials that can be found in almost every household: First, the fingerprint of the enroled user is photographed with 2400 dpi resolution. The resulting image is then cleaned up, inverted and laser printed with 1200 dpi onto transparent sheet with a thick toner setting. Finally, pink latex milk or white woodglue is smeared into the pattern created by the toner onto the transparent sheet. After it cures, the thin latex sheet is lifted from the sheet, breathed on to make it a tiny bit moist and then placed onto the sensor to unlock the phone. This process has been used with minor refinements and variations against the vast majority of fingerprint sensors on the market.”

Well, the reality is that no security system is 100% fool proof. Sooner or later there will always be someone out there that will spend time to bypass any security system implemented by Apple or any smartphone vendors because that’s what hackers do.

For the average users, this shouldn’t be a cause for concern because it does take some time and effort to do this, and may not be as easy as it looks.

Does this worry you?
