Abstract: A method of embedding authentication data in an electronic document image is described. Data related to an item of information on an image of at least one page in the electronic document is acquired. The image is decomposed into a hierarchy of images having a top level and one Or more lower levels each having a higher level parent, each lower level image defining a smaller region of the corresponding higher level parent image, the top level image defining a region that covers the item of information. A first secure identifier of at least the top level image is computed and arranged in a first data arrangement. A second secure identifier of the data related to the item of information is computed and arranged in a second data arrangement with the data related to the item of information. The first and second data arrangements are embedded in the electronic document.
