First, the definition of digital anti-counterfeiting
Digital anti-counterfeiting technology is an emerging anti-counterfeiting technology that was launched and developed in 1997 when relying on rapid development of information technology, network technology and computer technology.
Digital anti-counterfeiting is a social network anti-counterfeiting system that can be used in a nationwide and unified management system. The digital anti-counterfeiting network can directly link manufacturers, merchants, consumers and government departments to provide anti-counterfeiting inquiries, data statistics, logistics tracking, information services and other services.
Second, the advantages and disadvantages of digital anti-counterfeiting technology
As an emerging anti-counterfeiting technology, digital technology has advantages that other anti-counterfeiting technologies cannot match, as follows:
● Uniqueness. With digital as an anti-counterfeit marker, any anti-counterfeit number (digital ID) is unique and can only be used once. Counterfeiters cannot be copied for reuse.
● Reliability. Digital anti-counterfeiting condenses a number of high-tech technologies and has a unique anti-counterfeiting mechanism. Even if the counterfeiter can imitate the appearance of the marker, it cannot forge the use of the anti-counterfeit number connotation, and the imitation is very high.
● Simplicity. The Internet access computer, ordinary telephone, and mobile phone are used as the query identification terminal. The consumer authenticates by inputting the anti-counterfeit number, and the whole process is simple and quick, and the interaction is strong.
● Unity. By using digital anti-counterfeiting networks all over the country, it is possible to quickly establish a nationwide anti-counterfeiting anti-counterfeiting network, which is convenient for monitoring and unified management.
● Versatility. In addition to the anti-counterfeiting function, the anti-counterfeit number also has many functions such as performing prize sales.
●The performance price ratio is high. Low cost, wide coverage and easy to accept.
Of course, digital anti-counterfeiting technology is not omnipotent, it also has shortcomings, as shown below:
●The technical content of the anti-counterfeit label itself is low
The digital anti-counterfeit identifier is a carrier for anti-counterfeiting coding, and the anti-counterfeiting code is identified on the product by the identifier. The anti-counterfeiting function of the logo itself is very limited. At present, most digital anti-counterfeit labels on the market are easily forged, and the anti-counterfeit labels are not exquisite, and are not suitable for labeling products with exquisite packaging requirements.
● low query rate
The low query rate is a common problem in digital anti-counterfeiting. The main reasons are three points: First, digital anti-counterfeiting is a new thing, many consumers are not clear how to identify authenticity through inquiry; second, shopping malls, stores do not provide query tools, that is, inconvenient to query; third, the cost of inquiry is too high.
●Uniform identification method
Except for a small number of anti-counterfeiting companies that have directly coded on the production line, most anti-counterfeiting companies use only one type of anti-counterfeiting labeling method, which makes it impossible to apply in a large number of high-speed production lines and low value-added products, such as beverages. Small bag of food, cigarettes, etc.
●The machine cannot be read
At present, digital anti-counterfeiting labels that can satisfy consumers' inquiries on the market are unable to perform machine reading, which greatly hinders the promotion and application of digital anti-counterfeiting technology.
Third, digital anti-counterfeiting technology process
The digital anti-counterfeiting technology process is as follows
After the consumer purchases the product, the anti-counterfeit label is uncovered, and the anti-counterfeiting serial number is input through a series of channels such as telephone, internet access, etc. according to the label prompt, and enters the anti-counterfeiting database to identify the authenticity of the product. After the consumer enters the number, the database performs a search comparison. If the number is correct and the first inquiry is made, the system informs the consumer that the product is a genuine card; if the number is correct but has been queried, the system will inform the consumer that the number has been on a certain day of the year. Have been queried, beware of counterfeiting. We will have a general understanding of this process through the following figure.
Fourth, the application of digital anti-counterfeiting technology
Digital anti-counterfeiting technology has developed rapidly in China in recent years and has been widely used in the anti-counterfeiting of various commodities. Mainly used in the label, mainly paper-based scratch-off, uncovering and holographic uncovering and laser scratch-off identification of several labels.
1. Paper uncovering label
This logo is made of specialized technology and specialized materials. The logo is synthesized by both the top layer (uncovering layer) and the sub-layer (remaining layer). The sub-layer is an extremely thin resin film. According to the surface material and color of the object to be attached, a resin film having a different color can be used. For transparent, white (silver) and yellow (gold) colors, black or color security digital is printed on the resin layer. Printing color security digital can greatly improve the anti-counterfeiting performance of the logo. Mark the underlying printed digital and bond the top layer to the bottom layer. When the skylight on the surface is uncovered, it is digitally exposed for consumers to inquire.
2. Laser uncovering label
This logo is a double information carrier of holographic image plus printing and coding developed on the basis of embossed holography technology combined with multi-coat composite printing technology. The target consists of a top layer, a sublayer and a release layer. The surface layer (uncovering layer) is a laser image and has all the features of the laser anti-counterfeiting mark; the sub-layer (remaining layer) is an extremely thin resin film, and different resin films are used depending on the surface material and color of the object to be attached, It can be divided into three types: transparent, white (silver) and yellow (gold), and printed with anti-counterfeit digital on the resin layer.
3. Laser scratch-off logo
This logo is based on the laser marking, the surface is printed with anti-counterfeit digital, and then covered with special ink. The logo is easy to scrape, safe and reliable.
Scratch the coating input password to make a call or call the Internet or send a mobile phone SMS to check the authenticity of the product; the white letter in the middle of the dripping disappears, and the original is restored after 10 seconds; the under-detection test sees the hidden pattern "authentic"; once the logo is pasted, the logo The rise will be broken into many parts.
4. Print holographic disclosure logo
The printed holographic revealing logo is based on the "rule exposing" technology and is made by holographic, printing, and coding. This type of logo has all the features of the holographic logo, combined with the characteristics of the uncovering type, the rule is broken after the surface layer is uncovered, and the pre-made graphic information is displayed by the pasted object, and the surface of the logo is hollowed out, which is opposite to the graphic and yin of the bottom layer. The size is the same and the quantity is the same; the bottom layer is marked with a number for the consumer to inquire. The logo has multiple anti-counterfeiting functions, which are suitable for sealing, flat and the like.
Digital anti-counterfeiting technology has played an important role in the field of anti-counterfeiting in recent years, and its development momentum has increased, and the deep expansion of digital anti-counterfeiting technology has gradually become the development direction. The information network formed by digital anti-counterfeiting technology not only provides enterprises with anti-counterfeiting services, but also plays an extremely important role in enterprise management. The digital anti-counterfeiting system is an extension service of enterprise management functions, providing a large amount of timely and timely market information for enterprises, saving a large amount of investment for enterprises to build their own dedicated enterprise management network, which will surely bring various aspects such as production management and scientific scheduling. A far-reaching impact.
