  • METHOD FOR AUTHENTICATING A SECURITY ELEMENT BY SUPERIMPOSING N SHARED COLOUR IMAGES, AND SECURITY ELEMENT IMPLEMENTING SAID METHOD
    Publication number: 20150244727
    Abstract: A method for authenticating a security element by superimposing N shared colour images in order to obtain at least one target colour may include a phase of constructing an authenticator system that includes a step of selecting a target colour; a step of selecting a series of N decomposition colours which, by means of superimposition, together enable the target colour to be obtained; and a step of recording the N shared images each with a decomposition colour from the series. A security element comprising at least one shared image may be obtained according to the method.
