Holograms also grace currencies and passports in many countries. High security holograms are used on excise labels on liquor bottles in many states of India, as well as on bank demand drafts and a variety of government issued bonds and certificates.
Security holograms are very difficult to forge because they are replicated from a master hologram which requires expensive, specialized and technologically advanced equipment.
Since most of the security holograms are embossed holograms it is possible to make the mechanical copies of security holograms. These counterfeited holograms are very difficult to distinguish from genuine holograms. The present technologies used to authenticate a genuine hologram are based on visual technologies and are not much efficient.
Spatial profile analysis of security holograms will be a good and efficient method to authenticate a hologram. This method can be used to differentiate counterfeited holograms by analysis of profiles. Hence hologram counterfeiting and thereby product counterfeiting can be avoided in future using this method.

The majority of products that you can buy have a 13-digit number on them, which is scanned to get all the product details, such as the price. This 13-digit number is referred to as the ‘GTIN-13’ where ‘GTIN’ stands for Global Trade Item Number. Error control is used in barcodes because without it, there would be so many errors and people would end up being charged for the wrong products. Sometimes when a barcode is being scanned, the scanner won’t read the number and therefore the number has to be entered manually, which can lead to human error.
