Claim:
1. A method for automatically updating an electronic document to prevent execution by an unauthorized signatory, the method comprising: receiving, by an electronic signature service computing system and from a first client device associated with a sender, an electronic document to be electronically signed on behalf of an organization, wherein the electronic signature service is executed by a processing device; retrieving, by the electronic signature service computing system from a data structure used by the electronic signature service computing system and stored on a non-transitory computer-readable medium, organization data specifying an access right for the electronic document by indicating signatories that are authorized to electronically sign the electronic document, wherein the organization data is inaccessible to a first signatory identifiable from metadata of the electronic document; determining, by the electronic signature service computing system, that the first signatory associated with the electronic document is not authorized to electronically sign the document, wherein an absence of signature authority for the first signatory is determined from the retrieved organization data by performing operations comprising: preventing the first signatory from using a second client device for electronically signing the electronic document based on determining that the first signatory is not authorized to electronically sign the document, wherein preventing the first signatory from electronically signing the electronic document comprises transforming the metadata of the electronic document by removing, from the metadata, an identifier of the first signatory and adding, to the metadata, an identifier of a second signatory.
