  • Document verification method and system
    Patent number: 10102439
    Abstract: A method of and system for verifying a document, the method comprising generating verification information for the document, comparing the verification information with authentic verification information, and identifying differences between the document and an authentic document.
    Type: Grant
    Filed: January 6, 2009
    Date of Patent: October 16, 2018
    Assignee: Hewlett-Packard Development Company, L.P.

  • Processing of printed documents
    Patent number: 8238665
    Abstract: A document processing method comprises adding document markers to predetermined locations of an electronically stored document. These are printed with the document. The document is scanned and the scanned document markers are used to process the scanned image. This processing comprises at least pixel threshold setting, and determination of the locations of the scanned image which are to be processed to derive the pixels of a digital version of the document. This enables local deformations in the paper document to be corrected, and enables correct thresholds for the printing and scanning operations to be applied. The electronically stored document can be processed to derive a set of document properties which can be used when constructing the digital version.
