Abstract
The invention notably relates to generating a measure of authenticity of an object (20) comprising a surface (30) comprising or covered by a non-uniform preexisting layer (40). A marking (50) has been printed on the surface (30) so that a property of the preexisting layer (40) is detectable through at least part of the marking (50). The marking (50) comprises a machine-readable representation of a code. The method comprises imaging (s100) the marking (50); reading (s200) the code represented by the imaged marking; generating (s300) a signature based on the property of the preexisting layer (40) as detected by the imaging device (10) through at least part of the imaged machine-readable representation of the code; and generating of a measure of authenticity of the object (20) based on the read code and generated signature. The invention also relates to apparatuses, systems and computer programs for that purpose.
