Abstract
A data carrier, in particular a plastic card, has an authenticity feature (4) introduced thereon, which can be customized during radiation with a high-energy beam. The customizable authenticity features (4) consist of at least one magnetizable component, wherein the customizable authenticity features (4) are magnetically formed. The intensity and/or wavelength of the radiation is selected such that the customizable magnetic authenticity features (4) undergo a localized structural change during irradiation, wherein the magnetizable components of the customizable magnetic authenticity feature (4) are at least partially destroyed. Following the irradiation, the customized magnetic authenticity features (4) form an area of lesser or no magnetic field in the entire image.

- 18. A data carrier comprising at least one authenticity feature provided in said data carrier, which on irradiation with a high-energy beam is personalizable by means of changes in physical and/or chemical properties, wherein the at least one personalizable authenticity feature is composed of at least one magnetizable component, wherein the at least one personalizable authenticity feature is magnetically configured, wherein at least one from intensity or wavelength of the energy-rich beam is selected such that the at least one personalizable magnetic authenticity feature undergoes a local structural change on irradiation, and wherein the magnetizable component of the at least one personalizable magnetic authenticity feature is at least partially destroyed by the local structural change, so that the at least one personalized magnetic authenticity feature forms an area of lesser or no magnetic field in the overall image after irradiation.
