What makes a good security feature?
■ 3-step security level
■ Prerequisite 1: Target group must be able to identify the security feature
– Naked eye or testing device?
■ Prerequisite 2: Adequate technological hurdle against falsification
■ Prerequisite 3: Easy integration into manufacturing or marking

Nanotechnology
Color perceptionthrough refractionand interference
Iridescent Surfaces
■ No color pigments
■ Very fine structure of a
butterfly wing leads to specific
interference and color-
changing effect
■ Special sputtering technology
(PVD) of nano-scale layers on
films and other smooth
surfaces generate special
optical characteristics

Color perception through refraction and interference II
Iridescent Surfaces
■ Color-shift or other effects
that can identifiied by use of
optical readers
■ Varying color perception
depending on angle of vision
■ Parallel developments by
different organisations
currently in progress
■ Decorative security element
that is easy to memorize

Pigments applied by use of printing technology
Luminescent Nano Particles
■ Pigment is added to ink or
varnish
■ Not discernible in normal
lighting conditions
■ Particles are extremely heat-
and UV-stable, inert and can
be converted with all
conventional printing
techniques

Fluorescent Markers
■ Past: Tested only for existence of markers
■ Now: Definite identification of an optical signature (“an individual fingerprint“) using an IR spectroscope

Holographic InterferencePatterns
■ Decorative security feature
■ High counterfeiting protection
for experts
■ Easy combination with other
features, such as:
– UV or infrared ink
– Microtext with 30µm font
height
– Thermoreactive ink

Injection Molding –Holography
Nano-Structured Injection-Molded Surface
■ No additional process step
■ Advantageous for very small
parts
■ Diffractive, imaging effects
■ Holographic shim is
embedded in the mould

Moving forward to Success
■ “Small“ is not an end in itself; the objective is to deliver …
– …technologies that can be integrated into existing manufacturing processes in an efficient and
controlled manner.
■ Field applications always combine:
– Counterfeiting protection
– Tampering protection
– Traceability
■ Security features on a product must…
– …allow any layperson to easily and plausibly authenticate a product in order to strengthen confidence
in the brand
– …deter counterfeiters by combining overt and covert features
– …allow definite authentication by specialists to obtain findings that hold up in court.
