Abstract: A method of validating an identity document issued by an issuing authority to certify the identity of an identity document holder whose details are displayed by the identity document together with a first image of the identity document holder, wherein the issuing authority captures a second image of the identity document holder substantially at the same time as the identity document holder applied for the identity document, whereby calculating the pair of images a measure of the similarity of the images comprises the step of applying a plurality of face recognition algorithms to each image in the pair and calculating an accumulated score therefrom representing the degree of matching between the faces of the persons displayed in each image.

Abstract: A method of validating an identity document from a plurality of features extracted therefrom, wherein the features comprise a facial image and one or more personal detail elements of the identity document holder; and an identifier of an issuing authority who issued the identity document, wherein the method includes allowing an operator to define a value of a threshold for assessing the similarity of a pair of facial images, and wherein a measure of the similarity between the first facial image and the second facial image is calculated by applying a plurality of face recognition algorithms to the first facial image and the second facial image and calculating an accumulated score therefrom representing the degree of matching between the faces of the persons displayed in each facial image.

Abstract: A method, system and computer program product for validating a facial image-bearing identity document from the face pictured thereon, in which an image of a presented facial image-bearing identity document is compared with images of the faces of persons previously linked with the handling of an illegitimate document. In the event that a match is found, an alert message is transmitted and displayed to an operator and if no match is found a clearance message is transmitted to the operator.
