Electronic signature framework with keystroke biometric authentication

An electronic signature system comprising:

• a memory;
• a processor that is coupled to, and capable of executing instructions stored in, the memory;
• a registration module that is stored in the memory, the registration module comprising means for creating a keystroke biometric profile for an intended signatory;
• and
• an interactivity module that is stored in the memory, the interactivity module comprising
• means for performing an initial authentication of the intended signatory in response to receiving an initial request from the intended signatory to access an unsigned document,
• means for performing a subsequent authentication of the intended signatory in response to receiving a subsequent request from the intended signatory to apply an electronic signature to the unsigned document, and
• means for applying the electronic signature to the unsigned document, thereby creating an electronically signed document, in response to successful completion of the subsequent authentication.

A non-transitory computer readable medium encoded with instructions that, when executed by one or more processors, causes an electronic signature process to be invoked, the electronic signature process comprising:

• receiving, from a first computing device associated with a document originator in an electronic signature workflow, metadata that identifies a document that is to be distributed to a second computing device associated with an intended signatory in the workflow;
• transmitting, to the second computing device, instructions for accessing the document;
• making a first determination that no keystroke biometric profile is available for the intended signatory;
• in response to making the first determination, prompting the intended signatory to provide a first typing sample;
• generating a keystroke biometric profile for the intended signatory based on how the first typing sample was typed;
• providing the second computing device with access to the document;
• receiving, from the second computing device, a command to apply an electronic signature to the document;
• in response to receiving the command, prompting the intended signatory to provide a second typing sample;
• generating keystroke biometrics characterizing how the second typing sample was typed;
• making a second determination that the second typing sample was typed by the intended signatory based on a comparison of the keystroke biometrics with the keystroke biometric profile;
• and
• in response to making the second determination, applying the electronic signature to the document.
