2008, Al-Sarayreh, K. T. and Al-Qutaish, R. E., Enhancing the Security of E-Government Portals using Biometric Voice along with a Traditional Password.

The security is a very important characteristic for any e-government portal. In this paper, we have introduced a methodology to use the voice as a support security characteristic along with the traditional password. In this way, the security could be increased since the user needs to use his voice beside his password. Therefore, no any unauthorized person can enter the e-government portal even if he gets a password.
