摘要：
Procedure for verifying the integrity of documents which comprises a characterization of the original document to obtain a hash (508) and a stage of integrity verification, this stage comprising in turn, representing (601) the digital document to be verified in a matrix format adapting (602) said document to a determined resolution in the characterization and correcting (603) the inclination, obtaining a corrected image (604) obtaining (605), the displacement produced between the contents in the original document and the document to be verified obtaining (610) optimal displacement coordinates for each one of the regions of the corrected image obtaining (611 ) one metric from the quantified coefficients of the corrected image and the corresponding ones in the original document deciding (612) on the integrity of each region of the digitalized document using the previous metrics and finally deciding (613) on the integrity of the document based on the results of the previous step.
