Industries seek a solution that is better than the current manual entry two-factor (username/password) model. This “anyone can use it” model of security creates vulnerability across devices. Users need simplicity and privacy between work and personal.
Porticus’ suite of VoiceKeyID (“VKID”) Technologies run “on-device” and do not require additional hardware to implement. VKID can run on most major DSP chips or at Operating System level.


When embedded on a DSP, PATENTED Tetrad ties together:

1] the Device’s unique ID 
2] the user’s Location ID 
3] user’s voice biometric 
4] user’s passphrase.

The RESULT: Exponential Level of Security

Embedded DSP Solutions

  • VoiceKeyID – Embedded Biometric Engine
    Available for Qualcomm Snapdragon DSPs and others. Deploy VKID with unique Device IDs for TETRAD level 4-factor Security.  
  • VoiceKeyID/FacialID “Fused” solution
    Two algorithms running on chip deliver multi-modal interface of voice and face biometric as well as their “fused” capability in financial, government and other key transaction based applications. See A Specific Market For This Solution
  • Core Biometric Algorithm Technology
    Porticus’ patented technology is based on two-decades of Interpol funded research. This technology is used by European governments as a means of criminal identification.  Being based on voice forensic science ensures a true physical biometric reading of an individual, not just a statistical analysis.

Optimized for Mobile

The Porticus system was designed and optimized for mobile handsets. Other conventional speaker verification systems have been optimized for speech recorded from high quality microphones in ideal sound environments and require high bandwidth; neither condition being suitable for mobile telephony. The Porticus solution focuses on voiced phonemes (mostly the vowel sounds) since amongst other reasons vowels have higher energy (less susceptible to noise) and lower bandwidth (matching the narrow bandwidth available on mobile) than consonant sounds. Other systems that are made to fit onto the mobile platform suffer severe performance degradation. Additionally the Porticus algorithm has been optimized for the frequency range supported by telephony devices.


technology-lockThe voice biometric is fully secured against theft. This biometric template is not a recording of your voice but the result of a one-way transformation, i.e. an operation that cannot be reversed. The only way the algorithm will produce a positive result is to use another voice sample to compare against the template. A stolen biometric would be of absolutely no use to anyone; hacking attempts are rendered useless.
