1. In a computerized network system, a method for generation and authentication of a signed document over the network comprising the steps of: (a) providing to a service through an interactive interface provided by software executing from a digital storage medium associated with an Internet-connected server on the network providing the service, personal user data specific to a new system registrant, including textual or graphical digital data or images; (b) storing the user data provided in step (a) in a digital storage medium or memory associated with the server; (c) generating and providing to the new registrant unique enrollment session identifier and additional data required for continuing registration, said identifier and additional data displayable on a terminal data device connected to the system network and accessible by the registrant; (d) providing to the server via a telecommunications device initial voice samples of new registrant, said samples recorded, analyzed and stored along with personal data provided in step (a) in memory or other digital storage associated with the server; (e) assigning to the registered user a unique authentication certificate and storing said certificate in memory or other digital storage associated with the server; (f) uploading through a user data terminal device a new document to be certified and authenticated; (g) providing to the server via a telecommunications device current voice samples of new registrant, said samples recorded, analyzed and stored along with personal data provided in step (a) in memory or other digital storage associated with the server; (h) comparing in a voice comparison unit associated with the server current voice samples provided in step (g) with initial voice samples provided in step (d), and if matched, providing a corresponding output signal to a certification unit associated with the server, said signal generating a current authentication certificate; and (i) attaching the authentication certificate of step (h) to the document of step (f) wherein the document becomes a signed and authenticated document downloadable to the user's data terminal device, and verifiable by another querying user; wherein in practice of the method separate system channels are utilized for generation and authentication of the signed document, and document data is transmitted via a channel other than that for transmitting voice data, and generation and authentication of the signed document is accomplished by a single end user registered to the system wherein the single user is the signer of the document.
