Abstract
Computer-implemented methods, systems, and computer program products for document authentication and identification using a large-scale distributed system are provided. A method includes receiving a digitized document at a trusted system managed by a trusted third-party that is separate from a creator of content in the digitized document. The digitized document is compared to a set of markers to determine whether the digitized document includes one or more of the markers, and in response thereto, information associated with the one or more markers is extracted using a decoder on the trusted system according to encoding strategies. The method further includes generating a comparison registration identifier on the trusted system as a summary of the extracted information and the one or more markers, and comparing the comparison registration identifier with a stored registration identifier in an encoding history via the trusted system to authenticate and identify the received digitized document.
