Independent consultancy, research and evaluation of authentication technologies for document and product security
Holograms and Diffractive Optically Variable Image Devices (DOVIDs) are now used on banknotes, tax seals, passports, and security documents; holograms are used by Fortune 500 companies to protect their brands, yet some users claim that their security holograms are copied in Asia in a matter of weeks. Microsoft, for example, use holograms on their software CDs and promote validation via their “How to Tell” web pages, yet they admit that they are only ever a few steps ahead of the counterfeiters. What are brand owners to think and where can they get independent and impartial advice?
With decades of experience of authentication technologies and knowledge of holograms to PhD level, David Pizzanelli offers balanced, independent guidance to government departments, banks and brand owners wanting to authenticate their documents and products.
