Embossed holographic tags for security and anti-counterfeiting applications are being used by
industry since many years. However, such elements are not very effective since the detector is
usually the human eye, and provides therefore around 80% effective counterfeiting protection of
the tag. We present a novel holographic anticounterfeiting technology which provides 99.999%
protection against tag counterfeiting.
Horus Technologies develops such holographic tags, which include several layers of increasingly
secure optical features, from standard visual holographic patterns and OVIDs (Optical Variable
Imaging Devices), to micro-holographic text, down to covert features such as encrypted high
resolution holographic 1d, 2d and 3d bar codes. We also demonstrate the potential of providing
anti-tamper functionality on the same tag, for packaging security (especially for medical
packaging). Finally, we demonstrate that more than 1Mb/square mm of digital data can be stored
and encrypted on these same tags. A specific low cost laser based reader is developed to read the
various security feature of such hybrid universal holographic tags. We also present a way to
change and update the encrypted data in the tag in a similar way to RFID tags.
Finally, we show a cost effective technique to replicate these structures in volume by roll-to-toll
embossing, and even direct by glass molding within the package itself (bottle, vial, etc,..).
