Example 1
Referring to fig. 1, a flow chart of an implementation of the method for verifying the authenticity of the ribbon cartridge on the thermal transfer printing device according to the present invention is shown, and specific steps of the method will be described in detail below.
And step S11, reading the sequence information in the RFID electronic tag, calculating by using a first encryption algorithm by using the sequence information as a key to obtain a first verification password, and outputting the first verification password.
In specific implementation, the RFID electronic tag is also called an electronic tag, a radio frequency tag, a transponder, and a data carrier, and the RFID electronic tag can be coupled with a reader/writer through a coupling element to realize spatial (contactless) coupling of radio frequency signals; and in the coupling channel, energy transfer and data exchange are realized according to a time sequence relation. Namely, the data in the RFID electronic tag can be read (or written) by the reader/writer. Generally, there are two independent memory banks (banks) of UID (tag serial number) and User (User) in the RFID tag. Wherein the UID field is used to store tag identification numbers, each UID number should be unique. The User area is used for storing User-defined data, and the data in the User area can be encrypted or not encrypted according to the needs of the User.
In a specific implementation, reading the sequence information in the RFID tag refers to reading the sequence information preset in the User area, and specifically, the sequence information may be a User-defined character string (i.e., a User-defined character sequence). The purpose is to use the sequence information as a key to perform an encryption calculation to generate a password. But of course also an electronic product code in an RFID electronic tag, such as a tag serial number. Because the label serial number has uniqueness, the label serial number is used as sequence information to generate a password, so that the label encryption mode can be prevented from being changed, and the encryption reliability is improved.
Of course, in specific implementation, the sequence information may also be a combination or concatenation of several information in the tag identification number on the RFID electronic tag, the electronic product code on the RFID electronic tag, and the user-defined character sequence preset on the RFID electronic tag.
Step S12, receiving the first verification password and checking it with a first password preset in the RFID tag:
step S121, if the two are consistent, anti-counterfeiting verification is completed;
step S122, if not, entering into a verification failure processing mechanism.
In a specific implementation, the first password preset in the RFID tag is obtained by calculating sequence information according to a first encryption algorithm.
In a specific implementation, entering into the verification failure processing mechanism may specifically be displaying a reminding word such as "verification failure" or "please use the genuine product" on the device; in addition, an alarm signal can be sent out to remind the verification of failure.
Example 2
Referring to fig. 2, a schematic diagram of another embodiment of the method for verifying the authenticity of a thermal transfer printing ribbon cartridge on a thermal transfer printing apparatus according to the present invention is shown, and as shown in the drawing, unlike the foregoing embodiment 1, in the foregoing step S12, when receiving the first verification password and checking the first verification password with a first password preset in the RFID electronic tag, the method further includes the following steps:
in step S13, the verification result is determined to be consistent, and the anti-counterfeit verification is not directly completed.
Step S131, if the two are not consistent, the authentication failure processing mechanism is entered.
Step S132, if the two passwords are consistent, reading encrypted information and a second password preset in the RFID electronic tag, calculating by using a second encryption algorithm and taking the encrypted information as a secret key to obtain a second verification password, and checking the second verification password with the second password;
in step S14, it is determined whether or not the results match.
Step S141, if the two are consistent, the anti-counterfeiting verification is completed;
step S142 (not shown), if not, go to step S131;
and the first password is an access password for reading the encrypted information or/and the second password.
In a specific implementation, the encrypted information is one or a combination of several of a tag identification number on the RFID electronic tag, an electronic product code on the RFID electronic tag, the second password, and a user-defined character sequence (which may be the same as or different from the user-defined character sequence) preset on the RFID electronic tag.
In a specific implementation, the first encryption algorithm for encrypting the sequence information may be an encryption algorithm known in the prior art or a self-designed algorithm, and what algorithm is adopted is not critical to the implementation of the present invention, and can be selected according to the needs of the implementer.
Moreover, the first encryption algorithm and the second encryption algorithm generally adopt different encryption algorithms to improve the difficulty of being cracked, and certainly, the first encryption algorithm and the second encryption algorithm can also be two same encryption algorithms.
Example 3

In specific implementation, the controller 300 may be implemented by using chips such as a CPU or an MCU, the controller 300 is connected to the reader/writer 200, the RFID tag 100 is disposed on the carbon ribbon cartridge, and the RFID tag 100 and the reader/writer 200 are connected by wireless coupling, so that the situation of implementing anti-counterfeit verification by using a wired connection mode in the prior art is avoided, and the existing manufacturer does not need to re-open the mold to improve the carbon ribbon cartridge, but only needs to add a tag on the existing structure to implement the present invention.
In a specific implementation, reading the sequence information in the RFID electronic tag 100 means that the controller 300 reads the sequence information preset in the UID area through the reader/writer 200, and specifically, the sequence information may be a character string written by a user (i.e., a user-defined character sequence). The purpose is to use the sequence information as a key to perform an encryption calculation to generate a password. But of course also an electronic product code in the RFID tag 100.
Preferably, the sequence information is a tag identification number on the RFID electronic tag 100, which is used as a secret key to generate a password to provide security against counterfeiting since the sequence information is unique.
Of course, in specific implementation, the sequence information may also be a combination or concatenation of several information in the tag identification number on the RFID electronic tag 100, the electronic product code on the RFID electronic tag 100, and the user-defined character sequence preset on the RFID electronic tag 100.
Further, in the RFID tag 100, when the first verification password is received and checked with the first password preset in the RFID tag 100, if the check result is consistent, the anti-counterfeit verification is not directly completed, but the controller 300 performs the secondary verification. Specifically, if the check result is consistent, the controller 300 is further adapted to read the encrypted information and the second password preset in the RFID tag 100, calculate the encrypted information as a secret key by using a second encryption algorithm to obtain a second verification password, and check the second verification password with the second password, and if the check result is consistent, complete the anti-counterfeit verification; if not, entering a verification failure processing mechanism; and the first password is an access password for reading the encrypted information or/and the second password.
In a specific implementation, entering into the verification failure processing mechanism may specifically be displaying a reminding word such as "verification failure" or "please use the genuine product" on the device; in addition, an alarm signal can be sent out to remind the verification of failure.
In a specific implementation, the encrypted information is one or a combination of several of a tag identification number on the RFID electronic tag 100, an electronic product code on the RFID electronic tag 100, the second password, and a user-defined character sequence preset on the RFID electronic tag 100.
In a specific implementation, the first encryption algorithm for encrypting the sequence information may be an encryption algorithm known in the prior art or a self-designed algorithm, and what algorithm is adopted is not critical to the implementation of the present invention, and can be selected according to the needs of the implementer.
In addition, the first encryption algorithm and the second encryption algorithm generally adopt different encryption algorithms to improve the difficulty of being cracked, and certainly, the first encryption algorithm and the second encryption algorithm can also be two same encryption algorithms.
In conclusion, the carbon tape box anti-counterfeiting function can be added by a printer manufacturer only by slightly modifying the original printer core without the anti-counterfeiting function during production, so that the time and the cost for developing a new printer core by a manufacturer are reduced, and the time for selling a new product is increased; in addition, the invention adopts a unique encryption mode to carry out encryption verification on the carbon tape box, thereby ensuring that the carbon tape box is counterfeited or broken, and firstly detecting the authenticity of the carbon tape box before the printing process is implemented, thereby ensuring the legal benefit of a producer; and further ensures that the printing equipment is not damaged by using a forged carbon tape box in the using process of a customer, and simultaneously ensures that the printing quality is not influenced by using inferior consumables. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
