Anti-counterfeiting protects both consumer and brands.
Consumer actually needs two points:
1. We can verify it immediately!
2. The authentication method should not be replicable.
The fake goods are only sell to general people, like you and me. But the general anti-counterfeiting solution needs us to send it back to dealer for examination, or our eyes. The truth is, we might purchase a fake goods, but those manufacturer can’t.
1. Print: Easy to copy by only a Photostat.
2. Identify by internet:May be cheated by fake address.
Special ink,can not be clearly identified.Easy to imitate.
It’s hard to identify when the pictures looked similar, it’s easy to fake by printing.
Labels are similar, can not be clearly identified.The technique is common, easy to fake.
1.Many manufacturers of laser tag, so the bad guys are very easy to produce similar tags.
2.Customers can not identify clearly.
3.Many goods use laser labels to prevent fake, but there still have lots of fakes come out. Real and fake both have laser label on them, and they look similar, coustomers can not be defined. Although producers make new label, fake producers can also imitate, the problem still can not be solved.
Can be identified only one time.Fake phone number and website address are easy to defraud.
Digital label is a sticker with silver powder on it to cover the identify number. This kind of label is easy make. Faker can put fake information on it.
Only one identify number identified not only one time. It’s possible to be fake with blank RFID.
RFID now usually use in close system, only person who has reader with password can use. This kind of RFID can not publicly let all customers to use, because when everyone has the password, RFID will loose the effect to anti-counterfeit.
The other kind of RFID prevent fake with “only-one-number” and “hard to make”. But although normal people can not make the RFID, fake companies have the reason to get the technique and make. It is not that hard to fake the RFID now.
Ordinary RFID which use in anti-counterfeit label has two ways to prevent fake:
1. Uses encryption to transport identify number
This way has to use unique label and reader, only the corresponding reader can read the label. Because of this limit, it can only be used in small and closed unit, such as inner transport of single company. Customers can not identify by this way. If it wants to let all the customer can use, the encryption will be easily cracked. For example, many expensive cars uses “RFID remote-controlled key” to open door without touch. America John Hopkins University found out that, with only one notebook can crack the encryption signal and open. So that, this way can not use to identify real by customers when sopping.
2. Every RFID label has UID on it as the identify code
Every RFID label has UID(Unique Identifier) number, like every person has an ID number, and is all different.
This kind of label only depends on how hard to manufacture, doesn’t really has the efficacy to prevent fakes. This label can work when evildoers can not make the RFID label, but not now. During these years, the technique already spread to developing countries; include China, India, Russia, and so on. Because the factories are getting more and more, the technique of this RFID is no longer so difficult.
So that, when Ordinary RFID label which use in anti-counterfet is widespread, fake groups can buy “blank RFID label” (which fake groups can write real UID number on it) from factories. This blank RFID label is probable will come out and make the label lose it efficacy.
Problems of ordinary RFID
RFID now usually use in close system, only person who has reader with password can use. This kind of RFID can not publicly let all customers to use, because when everyone has the password, RFID will loose the effect to anti-counterfeit.The other kind of RFID prevent fake with “only-one-number” and “hard to make”. But although normal people can not make the RFID, fake companies have the reason to get the technique and make. It is not that hard to fake the RFID now.
How easy to fake an ordinary RFID now:
1.Almost all of semiconductor factories can make.
2.Almost all of wafer-foundry factories can make.
3.Wafer-foundry factories of whole world will increase to over thousand.
4.Wafer-foundry factories spread out whole world include America, Europe, China, Brazil, and so on.
If ordinary RFID use to prevent fake, it’s impossible for fake companies not to fake it. They can buy blank labels from factories and fill UID into blank RFID by themselves. Ordinary RFID can no lounger prevent fake.
