Abstract
A method for increasing validity of digital signatures comprising: receiving a request from a browser to have a user apply a digital signature to a document; verifying that the document complies with a predefined ruleset (e.g., prescribing font colors); presenting the user with the document on a user-computer interface in such a way that the document's entire content is completely reviewable by the user only if the document complies with the predefined ruleset; upon receiving instruction from the user to sign the document, generating a digital signature according to Advanced Encryption Standard (AES) public key infrastructure (PKI) that protects the document in its entirety, as presented to the user in the previous step; enabling the user to perform one or more of printing, sharing, and saving the digitally-signed document in a memory store; and sending the digitally-signed document with the newly-generated signature to the browser.
