Paper Abstract

In fraud prevention one of the most critical issues is how to distinguish a genuine document or object from a counterfeit. Most current technologies are based upon addition of a same, hard to counterfeit, addition to the document, like a hologram, a watermark or a graphical technique. Another approach is to add a unique property, which is different to each document. 3DAS is such a technique. 3DAS markers are all unique and can prove the authenticity of a document or object. They can also be used to identify objects and documents. This article explains the principles of 3DAS and informs the reader of the current status.
