The invention concerns a device which consists in affixing on the smallest possible surface (of the order of a few square centimeters) of an object, a characteristic shape (such as a double-edged rectangle) containing structured data so as to enable reconstruction of the traceability procedure of different operations to which an object or a product is subjected. Said characteristic shape is called traceability frame . Some of said data are designed to be read by humans (conventional writing, pictures and images). Other so-called coded data are designed to be read by optical scanning (two-dimensional codes, ECO, DOT writing and the like). The latter can be sealed and encrypted for secure use. The part consisting of coded writing comprises an identifier particular to each object and one or several tracers, which enable to locate straightaway the essential characteristics and, by means of links, detailed data from successive operators. Each marking (or label) comprises an individual encrypted reference guaranteeing its authenticity. Tables specific to each field of application (traceability tables) enable to reduce the number of coded characters contained in each traceability frame placed on each object. They also contain addresses of general operators of the field, such as certifiers. Said tables designated in the identifier can be loaded in the code scanners and the computerized servers of the operators.
