Systems and methods facilitating communication with remote computers
First Claim
1. A method comprising:
- receiving, using an electronic processor, a first image, wherein the first image represents a physical document;
extracting, using the electronic processor, from the first image a watermark steganographically embedded in the physical document, wherein the watermark comprises a document identifier;
obtaining, using the electronic processor, a first information derived from the first image, wherein the first information comprises a reduced-bit representation of the first image;
determining, using the electronic processor, a user account associated with the document identifier;
determining, using the electronic processor, whether the first information has been previously received; and
taking an action, using the electronic the processor, based upon the determination of whether the first information has been previously received and the user account.
