Abstract
Embodiments of the invention are directed to systems and methods for voice filtering. In some embodiments, an original voice segment from a user may be received. The received original voice segment may be modified using a first predetermined algorithm. The modified voice segment may be sent to an authentication server. At the authentication server, the modified voice segment may be reconstructed into the original voice segment using a second predetermined algorithm. The user may be authenticated for a transaction based at least in part on the reconstructed original voice segment.
