ABSTRACT:
A system for obtaining a digital signature incorporates two communication channels, and at least one of third-party data sources, geographic correlation algorithms, speech recognition algorithms, voice biometric comparison algorithms, and mechanisms to convert textual data into speech. A site visitor's identity can be verified using one or all of such features in combination with a visitors address on one of the channels.
