Abstract: Method and system for reading and validating identity documents that involves acquiring an image of a first and/or a second side of an identity document using a camera of a portable device; recognizing whether MRZ characters exist or are readable in the acquired image; if said MRZ characters are readable or do exist reading them obtaining a pre-identified document, or otherwise, detecting a series of local points of interests and their positions on the image calculating descriptors or vectors; and identifying the type or model of said identity document, starting by correcting perspective distortions caused by a bad relative position of the identity document with respect to the camera for obtaining a corrected and substantially rectangular image of the first and/or second side of the document at a predetermined scale which is used to perform, automatically, said identification of the identity document type or model and to automatically read and identify text and non-text information included in said corrected
