By Laura Maria Pulido Mancera, Sylvia Patricia Ceballos, Ivan Pulido, and Andrea Pacheco, Universidad Nactional de Colombia, Bogota, Colombia 


This video shows the basics and importance of security holograms for advertising and anti-counterfeit in several products like pharmaceutical drugs, innovative arts and advertising tickets. We include some videos about the research and manufacture of holograms in Colombia. We explain that holograms by themselves are First level security. This means that only the observation of the hologram give us information about the reliability of any product. We participate as the OSA-Student Chapter UNBOS.
