What is Tongueprinting Technology?

Tongueprinting technology analyzes thousands of tiny bumps called papillae, as well as factors such as shape, size, and temperature to accurately identify yourself by licking your phone. This technology will be the mouthpiece of Pindrop’s latest authentication and anti-fraud solutions.


Spacing and size of the papillae, or thousands of tiny bumps on the surface of the tongue, are analyzed to determine the tongue’s true print.


Our technology measures the shape and size of the tongue to ensure your identity is protected.


Rolling and curling are largely hereditary, but can be learned. We use a multi-factor approach to deter tongue spoofers from imitating your tongue’s print.

Why Tongueprinting?

Proprietary Tongueprinting technology takes only seconds – lick your phone and authentication is achieved.

  • A Protected Unit

    The tongue lives in your mouth, a protected unit, that is safe from external elements avoiding challenges facing other biometrics like frostbite, pink eye and laryngitis.

  • Health Advantages

    Pindrop research shows that licking your phone on average 47 times a day to unlock it, reduces the build up of bacteria and ultimately leads to healthier phone owners.

  • Experience

    Tongueprinting will open the door to a new set of consumer experiences – not only adding an extra layer of security, but increases opportunities to generate additional antibodies leading to a healthier user over time.
