Unauthorized persons won't enter your smartphone anymore.
VoiceUnlock makes easy and secure unlocking your device, using true voice biometrics technology based on DTec's BioVox Mobile engine for Android platforms. You don't need an Internet connection, all the processing is done locally in your phone.
What's the difference with other technologies? BioVox is text-independent voice biometrics technology, so you can register saying whatever you want and then unlock your device saying a completely different text. This leads to very important advantages:
- You are not forced to say a pre-defined text.
- You can use it in any language. You can even register in a language and unlock in a different one!
- Total Anti-Spoofing protection: secure against recording attacks, because it can be used together with a random speech recognition captcha (available in future versions of VoiceUnlock).
- If you wish, you can use a voice password only known to you (available in future versions of VoiceUnlock).
