Systems and methods for executing and delivering electronic documents

A computer system for annotating or signing an electronic document, the computer system comprising:

• a processor;
• and
• a non-transitory computer-readable memory device storing machine-readable instructions;
• wherein the processor is configured to, when executing the machine-readable instructions, perform the steps of:
• receiving or retrieving an electronic document available for annotation or execution by one or more parties;
• transmitting the electronic document for display on a first computing device to the first computing device at a first location;
• authenticating an identity of a first user of the first computing device;
• receiving electronic signals representing an user input of the first user from the first computing device, wherein the user input of the first user comprises a typed string;
• generating digital data representative of an indicia based the user input of the first user from the first computing device;
• applying the digital data to the electronic document to form a first annotation or signature from the first user;
• and
• rendering for display, at the first computing device, the first annotation or signature as a composite visual representation comprising at least:
• a first visual element showing the typed string rendered in a font selected by the first user;
• and
• a second visual element showing an unique hash code randomly generated based on a timestamp of the typed sting;
• wherein when a second user input is received from the first user, a different composite visual representation comprising a different hash code generated based on a timestamp of the second user input is rendered for display at the first computing device.
