Method and system for providing a way to verify the integrity of a document
First Claim
1. Method for providing a way for a user to verify integrity of a document, wherein the method comprises the following steps, in order:
- a) creating a digital signature of the document, associating the digital signature with the document and storing both the document and the digital signature in a central server;
b) publishing the document with a visibly embedded piece of information, the visibly embedded piece of information configured so that the digital signature is deducible from the visibly embedded piece of information;
c) receiving, from a device of the user, a visual depiction of the published document at the central server;
d) deducing, in the central server, a value from the visibly embedded piece of information visible in the received visual depiction, and finding the corresponding document stored in the central server based upon the visibly embedded piece of information; and
e) upon finding the document in the central server, communicating to the device of the user information configured for the user to verify the integrity of the document, the communicated information being the found document itself and/or information pertinent to the found document.

16. A system arranged to provide data to a user for the user to verify integrity of a document, the system comprising a computing device configured to:
-
a) create a digital signature of the document, associate the digital signature with the document and store both the document and the digital signature in the computing device; b) publish the document with a visibly embedded piece of information, the visibly embedded piece of information configured so that the digital signature is deducible from the visibly embedded piece of information; c) receive, from a device of the user, a visual depiction of the published document at the computing device; d) deduce, in the computing device, a value from the visibly embedded piece of information visible in the received visual depiction, and finding the corresponding document stored in the computing device based upon the visibly embedded piece of information; and e) upon finding the document in the computing device, communicate to the device of the user information configured for the user to verify the integrity of the document, the communicated information being the found document itself and/or information pertinent to the found document.
