A method for identification marking objects so that they may later be recognised should they be stolen, damaged, destroyed or modified. The method comprises using a number of recognition elements, i.e. a visible code such as a so-called INSEE code provided on the object to identify its owner, and an electronic code different from the above-mentioned code and characterised in that it is randomly and permanently determined at the industrial production stage, whereafter it may no longer be tampered with.
