IE-9 has developed a novel method of storing data utilizing state-of-the-art nanotechnology processes for high security authentication systems. Sample applications include banknotes, ID cards, passports, security documents, etc. The technology consists of a series of uniquely designed nano-structures that are 1,000 times smaller than the thickness of human hair. The optical effects created by these nano-structures result in a unique brightness and color signature. The structures are directly embedded into a wide variety of materials, such as transparent and colored plastic films, metallic foils, polymers and metals to store data of different formats ( simple text, PDF, media, video, audio, etc.) while providing a visual holographic effect simultaneously. It enables an initial level of authentication, and offers extremely secure physical data storage on transparent (or non-transparent) and flexible (or rigid) materials.
