The present invention relates to processes for marking a body with a view to its identification. The process according to the invention is characterised essentially in that it consists in producing, on a carrier, a first hologram of a first object readable under white light, in producing, on the same carrier, a second, so-called "Fourier", hologram of a second object, the said second object consisting of a plurality of point light sources, these sources being distributed randomly, and in tying the said carrier to the body. The subject of the present invention is also a device allowing the identification of the bodies when they have been marked by the process.
