Telephonic authentication

Using Speaker Verification, it is possible to unambiguously identify the user who is using the fixed or cellular telephone.
Using this technology within voice applications allows for the creation of robust authentication systems, such as:

• managing online transactions;
• granting access to closed application areas;
• remotely certifying the identity of the caller.

Authentication via web

Through the convergence between voice and web, DotVocal is today capable of offering biometric authentication not only through telephone, but also by internet.
The user can easily authenticate him or herself on a web site by using his or her own voice and a normal microphone attached to a computer.
This application of biometric technology on the web opens new scenarios, permitting access to protected areas of the web through biometric technologies which are simple to install and to use, and which unambiguously guarantee the identity of the user..

Speaker Verification

The voice imprint of a person is unique and is differentiated from all others based on the physiology of the vocal apparatus and the typical behavioural aspects of the sound production system.

Speaker Verification uses the voice imprint as a biometric measurement for verifying identity. The technology is extremely versatile, simple to use and non-intrusive, and therefore easily accepted by the users. Compared with other biometric technologies, it is very accurate and does not require the use of special equipment.

How it works

The voice authentication process requires two distinct phases:

• recording: initial phase of the process. This is carried out once by having the user pronounce several words. The recording is designed to capture and memorise the voice imprint of the user;
• verification the verification operation is repeated every time the service is requested and has the aim of accepting or refuting the declaration of identity. The verification consists of confronting the characteristics of the users voice during authentication with the model created previously for this identity.
