[0047] The printing device serial number is a string used to distinguish the printing device, which can specifically comprise a printing device ID, a printing device production batch and the like.

[0048] The method for obtaining the printing device serial number can be any feasible method.

[0049] In one embodiment, an RFID electronic tag is attached to the printing device, and the printing device serial number is obtained by reading the RFID electronic tag. This is a non-contact wireless communication method. Specifically, the printing device serial number can be stored in the RFID electronic tag, and the RFID electronic tag can be attached to a printing device component. If the RFID electronic tag is a passive tag, a wireless radio frequency signal is emitted by the reader in the first printing device control module, and the RFID electronic tag outputs the printing device serial number to the first printing device control module by means of the induced current. If the RFID electronic tag is an active tag, the RFID electronic tag actively outputs the printing device serial number to the first printing device control module at a certain specific frequency.

[0050] In another embodiment, a storage module is arranged on the printing device to store the printing device serial number, and the printing device serial number is obtained by contacting the output interface of the storage module through a conducting member. This is a contact wired communication method.

[0051] In another embodiment, a two-dimensional code containing the printing device serial number is printed on the printing device, and the user obtains the printing device serial number by scanning the two-dimensional code.

[0052] The printing device serial number is acquired, bit conversion is performed, and the encrypted information is sent to the second consumable control module.

[0053] The first check algorithm can be any implementation.

[0054] In S102, the second consumable control module receives the encrypted information, decrypts and restores the information, converts the decrypted and restored information into an n* bit first check sequence by using a first transposition algorithm, extracts an m* bit consumable check code by querying a preset first matching table, the first matching table stores a mapping relationship between a plurality of n* bit first check sequences and a plurality of m* bit consumable check codes, and sends the extracted m* bit consumable check code to the first consumable control module.

[0055] The second consumable control module decrypts and restores the received n bit encrypted information of the first check sequence, and then converts the n* bit first check sequence. n* is a positive integer different from n.

[0056] The first matching table stores a mapping relationship between a plurality of n* bit first check sequences and a plurality of m* bit consumable check codes in advance, that is, one-to-one correspondence between the two, and based on an n* bit first check sequence, a unique m* bit consumable check code corresponding to the n* bit first check sequence can be found.

[0057] The first transposition algorithm can be any implementation, for example, a base conversion algorithm.

[0058] In S103, the first consumable control module reads a consumable serial number, converts the consumable serial number into an m bit second check sequence by using a second check algorithm, converts the m bit second check sequence into an m* bit second check sequence by using a second transposition algorithm, checks whether the m* bit second check sequence is consistent with the m* bit consumable check code, if not, the verification fails, and if yes, S104 is started.

[0059] The consumable serial number is a string used to distinguish consumables, and can specifically include consumable ID, consumable production batch, and the like.

[0060] Similarly, the way of acquiring the consumable serial number can be any feasible way.

[0061] The second transposition algorithm can be any implementation, for example, a base conversion algorithm.

[0062] The first consumable control module checks whether the m* bit second check sequence is consistent with the m* bit consumable check code, wherein the m* bit second check sequence is calculated by the first consumable control module directly according to the read consumable serial number, and the m* bit consumable check code is obtained by the first printing device control module and the second consumable control module based on the printing device serial number. If not consistent, the verification fails, and if consistent, S104 is started.

[0063] At this point, the interactive verification of the consumable is completed.

[0064] S104, the first consumable control module converts the consumable serial number into an m-bit third check sequence by using a third check algorithm, and encrypts the m-bit third check sequence, and sends the encrypted information to the second printing device control module.

[0065] The first consumable control module obtains the printing device serial number, needs to be converted in bit number, so as to increase the cracking difficulty. After the bit number conversion, it is encrypted and sent to the second printing device control module.

[0066] S105, the second printing device control module receives and decrypts the information, converts the decrypted information into an m** bit third check sequence by using a third transposition algorithm, extracts an n** bit printing device check code by querying a preset second matching table, the second matching table stores a mapping relationship between a plurality of m** bit third check sequences and a plurality of n** bit printing device check codes, and sends the n** bit printing device check code to the first printing device control module.

[0067] The second printing device control module decrypts and restores the received m-bit first check sequence encryption information, and then converts it into an m** bit third check sequence. M** is a positive integer different from m.

[0068] The third transposition algorithm can be any implementation, for example, it can be a base conversion algorithm.

[0069] The first matching table stores a mapping relationship between a plurality of m** bit third check sequences and a plurality of n** bit printing device check codes in advance, that is, one-to-one correspondence between the two, so that one n** bit printing device check code corresponding to one m** bit third check sequence can be found.

[0070] S106, the first printing device control module converts the printing device serial number into an n* bit fourth check sequence by using a fourth check algorithm, converts the n* bit fourth check sequence into an n** bit fourth check sequence by using a fourth transposition algorithm, checks whether the n** bit fourth check sequence is consistent with the n** bit printing device check code, if not consistent, the verification fails, if the verification is consistent, S107 is started.

[0071] The fourth transposition algorithm can be any implementation, for example, a base conversion algorithm.

[0072] The first printing device control module checks whether the n**-bit fourth check sequence calculated directly by the first printing device control module according to the printing device serial number is consistent with the n**-bit printing device check code obtained by the first consumable control module and the printing device second control module based on the printing device serial number. If not, the verification fails, and if yes, S107 is started.

[0073] At this point, the interactive verification of the printing device is completed.

[0074] S107, the first printing device controller or the second printing device controller arranges the printing device serial number and the consumable serial number into a first sequence in a predetermined format and method, generates a random code, arranges the first sequence and the random code into a second sequence in a predetermined format and method, encrypts the second sequence, and sends it to the cloud server.

[0075] In order to further improve the cracking difficulty, and in order to facilitate the tracing of cracking behavior, and also to avoid interception and tampering in the data transmission process, the printing device serial number and the consumable serial number need to be processed and encrypted before being sent to the cloud server in the embodiment of the application.

[0076] A random number generation algorithm can be used to generate an a-bit random code. The first sequence is denoted as X, the a-bit random code and the first sequence X are arranged into a second sequence, denoted as Y, and Y is sent to the cloud server after being encrypted.

[0077] S108, the cloud server receives and decrypts the information, respectively obtains the restoration information of the printing device serial number and the consumable serial number, calculates the restoration information of the printing device serial number and the consumable serial number into a k-bit fifth check sequence using a fifth check algorithm, extracts a k-bit fifth check code by querying a preset third matching table, the third matching table stores the correspondence between a plurality of printing device serial numbers, a plurality of consumable serial numbers and a plurality of k-bit fifth check codes, checks whether the k-bit fifth check sequence is consistent with the k-bit fifth check code, if not, the verification fails, if the verification is consistent, the cloud server sends a start code to the printing device, and the printing device starts printing work after receiving and verifying the authenticity of the start code.

[0078] An example of the third matching table is shown in Table 1.

[0079] The printing device serial number is x i, 1≤i≤N, the consumable serial number is denoted as y j , 1≤j≤M, the fifth check sequence of the corresponding k-bit is denoted as z ji . Assuming that the restoration information of the printing device serial number is x2, the restoration information of the consumable serial number is y1, and the corresponding fifth check sequence of the k-bit is z according to the table 12 . The fifth check algorithm is used to calculate the restoration information x2 of the printing device serial number and the restoration information y1 of the consumable serial number into the fifth check sequence of the k-bit, denoted as z' 12 . Whether z 12 and z' 12 are consistent, if not, the verification fails, if the verification is consistent, the cloud server sends a start code to the printing device. After receiving the start code, the printing device verifies the authenticity of the start code, and then starts the printing work.

The printing device includes a first printing device control module and a second printing device control module, and the consumables include a first consumables control module and a second consumables control module. The method includes the following steps: S101, the first printing device control module reads the printing device serial number, uses a first verification algorithm to convert the printing device serial number into an n-bit first verification sequence and encrypts it, and sends the encrypted information to the second consumables control module; S102, the second consumable control module receives the encrypted information and decrypts and restores it, and uses a first transposition algorithm to convert the decrypted and restored information into an n*-bit first verification sequence. It extracts an m*-bit consumable verification code by querying a preset first matching table. The first matching table stores the mapping relationship between multiple n*-bit first verification sequences and multiple m*-bit consumable verification codes. The extracted m*-bit consumable verification code is sent to the first consumable control module. S103, the first consumable control module reads the consumable serial number, uses the second verification algorithm to convert the consumable serial number into an m-bit second verification sequence, and uses the second transposition algorithm to convert the m-bit second verification sequence into an m*-bit second verification sequence. It then checks whether the m*-bit second verification sequence is consistent with the m*-bit consumable verification code. If they are inconsistent, the verification fails. If they are consistent, S104 is initiated. S104, the first consumable control module uses a third verification algorithm to convert the consumable serial number into an m-bit third verification sequence and encrypts it, and then sends the encrypted information to the second printing device control module; S105, the second printing device control module receives the information and decrypts and restores it. It then uses a third transposition algorithm to convert the decrypted and restored information into an m**-bit third check sequence. It extracts an n**-bit printing device checksum by querying a preset second matching table. The second matching table stores the mapping relationship between multiple m**-bit third check sequences and multiple n**-bit printing device checksums. Finally, it sends the extracted n**-bit printing device checksum to the first printing device control module. S106, The first printing device control module uses the fourth verification algorithm to convert the printing device serial number into an n*-bit fourth verification sequence, and uses the fourth transposition algorithm to convert the n*-bit fourth verification sequence into an n**-bit fourth verification sequence. It then checks whether the n**-bit fourth verification sequence is consistent with the n**-bit printing device verification code. If they are inconsistent, the verification fails. If they are consistent, S107 is started. S107, the first printing device control module or the second printing device control module arranges the printing device serial number and the consumable serial number into a first sequence according to a predetermined format and method, generates a random code, arranges the first sequence and the random code into a second sequence according to a predetermined format and method, encrypts the second sequence and sends it to the cloud server; S108, the cloud server receives and decrypts the information, obtains the restored information of the printing device serial number and consumable serial number respectively, and uses the fifth verification algorithm to calculate the restored information of the printing device serial number and consumable serial number into a k-bit fifth verification sequence. The k-bit fifth verification code is extracted by querying a preset third matching table. The third matching table stores the correspondence between multiple printing device serial numbers, multiple consumable serial numbers and multiple k-bit fifth verification codes. The k-bit fifth verification sequence and the k-bit fifth verification code are checked to see if they are consistent. If they are inconsistent, the verification fails. If they are consistent, the cloud server sends a start code to the printing device. The printing device receives and verifies the authenticity of the start code and then starts printing.
