防伪技术的应用原来仅局限于货币、各种有价证券及可能危及全社会公共安全的特种行业。近年来,由于假冒活动日益严重,出于防范的需要,采用防伪技术越来越受到各国名牌产品企业的重视,激光全息、荧光油墨、温变油墨等许多常规的防伪技术已得到广泛应用。与此同时,各国竟相开发技术含量高、信息量大、保密性强、不可逆变、不可复制的新的防伪技术和防伪产品,并应用到各种类型的商品上。
The application of anti-counterfeiting technology turned out to be limited to currency, all kinds of securities and special industries that may endanger public safety in the whole society. In recent years, due to the increasingly serious counterfeiting activities, out of the need of prevention, the use of anti-counterfeiting technology has attracted more and more attention from famous brand enterprises in many countries. Many conventional anti-counterfeiting technologies such as laser holography, fluorescent ink and temperature-changing ink have been widely used. At the same time, all countries have instead developed new anti-counterfeiting technology and anti-counterfeiting products with high technological content, large amounts of information, strong confidentiality, irreversible changes and non-duplicability, and applied them to various types of goods.
