Abstrakt

Security documents are valuable documents protected by a mixture of security fea­tures, starting from security paper, inks, printing techniques, and additional security prop­erties. However, this article will discuss the main security features, supported by genuine and forged examples, to demonstrate the most frequent modern use of security features to protect valuable documents, and giving useful hints to detect forgeries and imposters as well.
