It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0034] like Figure 1 As shown, the present invention provides an anti-counterfeiting identification method and system for consumables, which are described below respectively.
[0035] An anti-counterfeiting identification method for consumables according to an embodiment of the present invention comprises the following steps:
[0036] S101, a first control module of a printing device reads a consumable serial number x, and uses a first coding algorithm f1 to calculate the consumable serial number x into a sequence f1(x), encrypts f1(x), and sends it to a cloud server.
[0037] The consumable serial number x is a character string used to distinguish consumables.
[0038] The method of obtaining the consumable serial number x may be any feasible method.
[0039] In one embodiment, an RFID electronic tag is attached to the consumables, and the consumable serial number x is burned on the RFID electronic tag. The consumable serial number x is obtained by reading the RFID electronic tag. If the RFID electronic tag is a passive tag, the reader in the control module of the printing device sends a wireless radio frequency signal, and the RFID electronic tag outputs the consumable serial number x to the printing device by means of the induced current. If the RFID electronic tag is an active tag, the RFID electronic tag actively outputs the consumable serial number x to the printing device at a specific frequency.
[0040] In another embodiment, a two-dimensional code containing information of the consumable serial number x is printed on the consumable, and the user obtains the consumable serial number x by scanning the two-dimensional code.
[0041] The first encoding algorithm may be any encoding algorithm, and may be pre-stored in the printing device, or may be stored in a cloud server, and the first encoding algorithm may be called from the cloud server for calculation.
[0042] S102, the cloud server decrypts the identification sequence f1(x) from the received information, queries the print quantity authorization table based on f1(x) to determine the authorized quantity in decimal. If the authorized quantity is not zero, the authorized quantity in decimal is converted into an authorized quantity y in n-base, and f1(x) and y are mixed into a new sequence z. The second encoding algorithm f2 is used to calculate the sequence z into a sequence f2(z), and f2(z) is encrypted and sent to the second control module of the printing device. If the authorized quantity is 0, the cloud server notifies the printing device to stop working.
[0043] The print quantity authorization table stores the authorization quantities in decimal that correspond to f1(x) one by one. The unique authorization quantity in decimal can be queried based on f1(x).
[0044] When f1(x) and y are mixed into a new sequence z, the characters in f1(x) and y are mixed and arranged.
[0045] n is a positive integer not equal to 10.
[0046] The second encoding algorithm f2 may be any preset encoding algorithm.
[0047] S103, the second control module of the printing device decrypts the identification sequence u from the received information, uses the third encoding algorithm to separate the sequence y, and converts the sequence y into a decimal sequence y*, records the remaining sequence as g, and uses the first transposition algorithm to convert the sequence g into an m-bit sequence h; the second control module of the printing device reads the printing device serial number, and uses the second transposition algorithm to convert the printing device serial number into an a-bit sequence k; the second control module of the printing device checks whether there is a preset functional relationship between the m-bit sequence h and the a-bit sequence k. If not, the verification fails; if so, execute S104.
[0048] The printing device serial number is a string used to distinguish printing devices.
[0049] Similarly, the method of reading the serial number of the printing device can be any feasible method.
[0050] For genuine consumables, it is assumed that there is a preset functional relationship between the m-bit sequence h and the a-bit sequence k after the same processing. Therefore, the authenticity of the consumables can be verified by verifying whether there is a preset functional relationship between the m-bit sequence h and the a-bit sequence k.
[0051] S104, the printing device records the authorized quantity y* and starts to execute the printing work. Every time a consumable label paper is printed, the authorized quantity y* is reduced by 1. When y*=0, execute S101.
[0052] After the verification is passed, the printing device can perform the printing work, but after one verification is passed, the maximum amount that the printing device can print is the authorized amount y*. After printing y* sheets, it is necessary to re-execute S101 and re-verify.
[0053] Furthermore, the print quantity authorization table is pre-stored in the cloud server, and the print quantity authorization table records the M authorization quantities [P1, P2, P3...PM] corresponding to f1(x), wherein Pm represents the authorization quantity when S102 is executed for the mth time, 1≤m≤M, and the authorization quantity for each execution of S102 is determined according to Pm in S102. When the number of grants is equal to M, then when y*=0 in S104, S101 is no longer executed.
[0054] That is, when step S102 is executed for the first time, the first authorization quantity P1 is determined according to the print quantity authorization table; when step S102 is executed for the second time, the second authorization quantity P2 is determined according to the print quantity authorization table; when step S102 is executed for the third time, the third authorization quantity P3 is determined according to the print quantity authorization table; and so on. When step S102 is executed for the Mth time, the Mth authorization quantity PM is determined according to the print quantity authorization table. When PM sheets of label paper are printed in S104, S101 is no longer executed, and the cloud server notifies the printing device to stop working.
[0055] Furthermore, P1, P2, P3, ..., PM are all greater than zero, and the sum of P1, P2, P3, ..., PM is not greater than the maximum print quantity of the consumables. That is, the authorization quantity each time should be greater than zero, and the cumulative authorization quantity is not greater than the maximum print quantity of the consumables.
[0056] Furthermore, n, m, and a are all any positive integers greater than 0 and less than 99.
[0057] Furthermore, the consumable serial number x is generated using a preset first random code generation algorithm and burned into the consumable during the production process. The consumable serial number x may include a production date, model, random code, etc. Burning refers to engraving the consumable serial number x into the consumable storage medium.
[0058] Furthermore, the consumable serial number x is burned into the RFID electronic tag of the consumable. The RFID electronic tag supports a contactless communication method, which can avoid major changes to the structure of the consumable and the printing device.
[0059] Furthermore, the printing device serial number is generated using a preset second random code generation algorithm and burned into the printing device during the production process. The printing device serial number may include a production date, model, random code, etc. Burning refers to engraving the printing device serial number into the storage medium of the printing device.
[0060] Furthermore, the serial number of the printing device is burned into the RFID electronic tag of the printing device. The RFID electronic tag supports a contactless communication method, which can avoid major changes to the consumables and the structure of the printing device.
[0061] According to another aspect of the present invention, there is provided an anti-counterfeiting identification system for consumables, including consumables, a printing device and a cloud server, wherein the printing device includes a first control module of the printing device and a second control module of the printing device, and the system is used to implement the steps:
[0062] S101, a first control module of a printing device reads a consumable serial number x, and uses a first encoding algorithm f1 to calculate the consumable serial number x into a sequence f1(x), encrypts f1(x) and sends it to a cloud server;
[0063] S102, the cloud server decrypts the identification sequence f1(x) from the received information, queries the print quantity authorization table according to f1(x) to determine the authorized quantity in decimal, if the authorized quantity is not zero, converts the authorized quantity in decimal into the authorized quantity y in n-ary, mixes f1(x) and y into a new sequence z, calculates the sequence z into a sequence f2(z) using the second encoding algorithm f2, encrypts f2(z) and sends it to the second control module of the printing device, if the authorized quantity is 0, the cloud server notifies the printing device to stop working;
[0064] S103, the second control module of the printing device decrypts the identification sequence u from the received information, separates the sequence y by using the third encoding algorithm, and converts the sequence y into a decimal sequence y*, records the remaining sequence as g, and converts the sequence g into an m-bit sequence h by using the first transposition algorithm; the second control module of the printing device reads the printing device serial number, and converts the printing device serial number into an a-bit sequence k by using the second transposition algorithm; the second control module of the printing device checks whether there is a preset functional relationship between the m-bit sequence h and the a-bit sequence k, if not, the verification fails; if yes, execute S104;
[0065] S104, the printing device records the authorized quantity y* and starts to execute the printing work. Every time a consumable label paper is printed, the authorized quantity y* is reduced by 1. When y*=0, execute S101.
[0066] Furthermore, the print quantity authorization table is pre-stored in the cloud server, and the print quantity authorization table records the M authorization quantities [P1, P2, P3...PM] corresponding to f1(x), wherein Pm represents the authorization quantity when S102 is executed for the mth time, 1≤m≤M, and the authorization quantity for each execution of S102 is determined according to Pm in S102. When the number of grants is equal to M, then when y*=0 in S104, S101 is no longer executed.
[0067] The working principle and technical effects of the system are the same as those of the above-mentioned method and will not be repeated here.
