Abstract:
1. A computer-implemented method for encoding identification information in a document using a large-scale distributed system, comprising: receiving a digitized document at a trusted system of the large-scale distributed system, the trusted system managed by a trusted third-party separate from a creator of content in the digitized document; creating a set of markers associated with identification information; selecting an encoding strategy to apply the set of markers to the digitized document as identifying tags; applying the set of markers to the digitized document according to the encoding strategy using an encoder on the trusted system to produce a registration identifier uniquely identifying the digitized document, the encoding strategy including masking regions of the digitized document as areas to avoid applying the encoding strategy based on determining that the regions of the digitized document are expected to be modified; and storing the registration identifier in an encoding history via the trusted system.
