Systems and methods for identifying a printer that generated a printed document. The methods comprise: generating an electronic image of the printed document; obtaining a dot pattern contained on the printed document via an analysis of the electronic image; overlaying the dot pattern on Voronoi diagrams; selecting a first Voronoi diagram from the Voronoi diagrams that has a single dot of the dot pattern in each of at least some cells thereof; and identifying a printer associated with the first Voronoi diagram that was selected from the Voronoi diagrams. The printer associated with the first Voronoi diagram comprises the printer that generated a printed document.

A print management service facilitates the secure exchange of print job information between a client who requests a print job and multiple candidates who may wish to bid on the job. The service generates a smart contract that includes some information about the print job but that omits other information, such as the content to be printed. When a print service provider submits a qualifying bid to a processor that executes the smart contract, the smart contract will award the job to that provider, and the print service provider will then receive access to the full content of the print job. The smart contract may require proof of work to trigger payment from the client to the service provider upon completion of the print job.
