Abstract

A system and method for electronic signature validation is provided. Embodiments may include analyzing at least one government identification document, wherein analyzing includes authenticating the at least one government identification document. Embodiments may further include extracting personally identifiable information pertaining, to a user from the at least one government identification document and displaying a digital copy of a document to be signed to the user. Embodiments may also include capturing an electronic signature of the document by the user and receiving personally identifiable information, wherein the personally identifiable information pertains to the user and enables the user to be uniquely identified. Embodiments may further transmitting a document signing transaction session.

Claims (48)

1 . An electronic signature validation method comprising:

receiving, via at least one network, from a remote device, a copy of at least one government identification document associated with a user, wherein the at least one government identification document comprises a reference image of the user;

transmitting, via the at least one network, to the remote device, a copy of a digital document to be displayed to the user;

receiving, via the at least one network, from the remote device, an electronic signature of the digital document by the user, wherein the electronic signature is captured during a document signing session, wherein the document signing session is attended by the user and an observer who observes an act of signing by the user during the document signing session;

generating one or more identity challenge questions to be displayed to the user during the document signing session;

in response to displaying the one or more identity challenge questions to the user during the document signing session, receiving, via the at least one network, from the remote device, input by the user comprising one or more responses to the one or more identity challenge questions;

analyzing the copy of the at least one government identification document, wherein the analyzing includes authenticating the at least one government identification document;

further receiving, via the at least one network, from the remote device, first personally identifiable information, wherein the first personally identifiable information includes at least one real-time image of the user and enables the user to be uniquely identified;

causing to display, side by side, the at least one real-time image of the user and the reference image of the user;

locking, using a digital certificate associated with the observer, the signed digital document to bind the digital document to the observer; and

storing, in at least one storage device, a record of the document signing session, wherein the record comprises the signed digital document, the copy of the at least one government identification document, the one or more responses to the one or more identity challenge questions, and video recordings of both the user and the observer using one or more cameras.

2 . The electronic signature validation method of claim 1 , wherein:

the copy of the at least one government identification document is captured, at least in part, using a document scanner configured to scan the at least one government identification document associated with the user.

3 . The electronic signature validation method of claim 1 , wherein the one or more cameras are associated with the remote device, and wherein:

the at least one real-time image of the user is captured during the document signing session using the one or more cameras associated with the remote device.
