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.

Large-scale document authentication and identification system

Computer-implemented methods, systems, and computer program products for document authentication and identification using encoding and decoding are provided. A method includes receiving a digitized document and comparing the digitized document to a set of markers to determine whether the digitized document is an encoded document with one or more characters replaced. In response to determining that the digitized document is encoded, information is extracted from the set of markers using a decoder according to an encoding strategy. The extracted information and the set of markers are compared with data stored in encoding history to authenticate and identify the received digitized document. Markers in the encoded document may be hidden in plain sight, such that the encoding is not readily apparent to a casual observer.

Document authentication and identification

An exemplary embodiment of the present invention is a method and system for isolating dropped packets in a computer network. A request for network analysis that includes a source node and a destination node is received by the invention. A map of the expected path between the two points, including the probes along the route is then generated. A capture filter profile for each probe along the route is created. A request to perform data collection is transmitted, along with the capture filter profile, to each of the probes along the route. Data is received back from the data collection in the form of a data log. Exception data is generated by comparing the data log to the expected path between the two points. Additional embodiments include a system and storage medium for isolating dropped packets in a computer network.
