Alternatively, in another example, it can preset when printer is imaging cartridge power supply, triggering printer carries out identity to imaging cartridge
Verification.
In the embodiment of the present invention, printer send certification instruction in carry appointment codes, at this point, send certification instruct to
The process of consumable chip can include but is not limited to following three kinds of situations：
The first, when printer is needed to send certification and be instructed to consumable chip, interim generation one is according to recognizing every time
Then the certification for carrying appointment codes, is instructed hair by the appointment codes that the program compiled format of card consumable chip is compiled
Give consumable chip.
At this time, it may be necessary in advance in printer pre- setting authentication consumable chip program compiled format.
It second, in printer, compiles to obtain appointment codes according to the program compiled format of certification consumable chip in advance,
And this appointment codes is stored in a designated storage location；Later, consumptive material core is given when printer needs transmission certification to instruct
During piece, the appointment codes of this designated storage location storage are just called, the certification for carrying appointment codes instruction is sent to consumption
Material chip.
The third, printer receives the appointment codes that Third Party Authentication equipment is sent, this appointment codes is that third party recognizes
Card equipment is compiled according to the program compiled format of certification consumable chip；Then, the appointment codes that printer will receive
It is stored in a designated storage location；Later, when printer needs transmission certification to instruct to consumable chip, just this is called to refer to
Determine the appointment codes of storage location storage, the certification for carrying appointment codes instruction is sent to consumable chip.
In the embodiment of the present invention, for Third Party Authentication equipment without being particularly limited to and, when sending out in this way
When sending the certification to instruct to consumable chip, how the embodiment of the present invention obtains third party device the realization side of this appointment codes
Formula is without being particularly limited to.For example, it can be compiled in Third Party Authentication equipment according to the program of pre-stored certification consumable chip
Translate form generation appointment codes；It is compiled alternatively, third party device can also receive administrative staff according to the program of certification consumable chip
Translate the appointment codes of form compiling.
It should be noted that the embodiment of the present invention to the program compiled format in consumable chip without being particularly limited to, example
Such as, program compiled format can include but is not limited to：The use of code format, register cannot cover, storehouse must balance.
For example, if the program in consumable chip is the binary code being compiled according to a specified rule,
Printer needs transmission certification to instruct to before consumable chip, and necessarily this section of appointment codes are compiled according to this specified rule
It translates, to obtain meeting the appointment codes of consumable chip Program compiled format.
In the embodiment of the present invention, the certification for carrying appointment codes instruction directly can be sent to consumptive material core by printer
Piece；Alternatively, certification can also be instructed and carry out data processing, then, data will be passed through before printer sends certification instruction
Certification that treated instruction is sent to consumable chip.
Specifically, in the embodiment of the present invention, the mode for carrying out data processing is instructed to can include but is not limited to certification：Add
It is at least one in close processing and compression processing.
In the embodiment of the present invention, the certification for carrying appointment codes instruction is sent to consumable chip by printer, then, when
After consumable chip receives this certification instruction, consumable chip can run this appointment codes, and will obtain operation result
Return to printer.Since appointment codes are compiled according to the compiled format of certification consumable chip, if consumable chip is
Certification consumable chip, then, the operation result that consumable chip returns to printer is necessarily correct；If alternatively, consumable chip
It is not certification consumable chip, then, consumable chip can not just run this section of appointment codes or obtain the operation result of mistake, because
This, the operation result that printer receives is wrong.
Based on this, printer when whether determine consumable chip be certification consumable chip, can be first judged according to operation result
Whether the operation result received is correct, and when operation result is correct, it is certification consumable chip to determine consumable chip；Alternatively, work as
When operation result is incorrect, it is not certification consumable chip to determine consumable chip.In this way, printer can just be returned according to consumable chip
The operation result returned, determines whether consumable chip is certification consumable chip.
It should be noted that printer judges whether operation result correctly can be there are many realization method, and the present invention is implemented
Example is to this without being particularly limited to.In order to be more particularly described this programme, the embodiment of the present invention provides following two realization methods, this
Two kinds of realization methods are only to illustrate this programme, not limiting the application.
For example, can be when printer generates appointment codes, while preset the correct operation result of this section of appointment codes；Such as
This, after the operation result for receiving consumable chip return, the correct operation result that operation result is stored with itself is compared
Compared with, if operation result is consistent with correct operation result, it is correct to determine that operation result, and then, it is certification to determine consumable chip
Consumable chip.Alternatively, if operation result and correct operation result are inconsistent, determine that operation result is incorrect, and then, determine consumption
Material chip is not certification consumable chip.
Alternatively, in another example, after printer is sent to consumable chip certification instruction, this section of printer self-operating specifies generation
Code, obtains a correct operation result；In this way, after the operation result for receiving consumable chip return, by operation result and certainly
The correct operation result that body is run is compared, if operation result is consistent with correct operation result, determines that operation result
To be correct, and then, it is certification consumable chip to determine consumable chip.Alternatively, if operation result and correct operation result are inconsistent, just
Determine that operation result is incorrect, and then, it is not certification consumable chip to determine consumable chip.
During a concrete implementation, if consumable chip, which returns to, includes verification letter in the operation result of printer
Breath, then printer just can further judge whether operation result is correct after detecting that check information is correct；If alternatively, printing
It is incorrect that machine examination measures check information, it is believed that the information received is not operation result, alternatively, operation result is incorrect.
The technical solution of the embodiment of the present invention has the advantages that：
In the embodiment of the present invention, printer, which is sent in the certification instruction of consumable chip, includes appointment codes, this refers to
Determining code is compiled according to the program compiled format of certification consumable chip, that is to say, that only certification consumable chip
It can correctly identify and run this appointment codes, and obtain correct operation result；And illegal compatibility consumable chip is nothing
Method identifies or can not run this appointment codes, even if this code can be run, also differs and is surely correctly run
As a result.Based on this, in the embodiment of the present invention, consumable chip runs appointment codes and obtains after certification instruction is received and identified out
To operation result, if operation result is correct, it is possible to which it is certification consumable chip to determine consumable chip；If it alternatively, obtains
Operation result is wrong, that is assured that consumable chip is not certification consumable chip, so as to which printer can be according to consumptive material
The operation result of chip realizes the certification to consumable chip, and eliminates illegal compatibility consumable chip.Therefore, the present invention is implemented
The technical solution that example provides can solve in the prior art that there are security holes for authentication method of the printer to consumable chip
Problem.
Embodiment two
The embodiment of the present invention provides a kind of chip authentication method, and this method is implemented on consumable chip.
Specifically, it please refers to Fig.2, the flow of the embodiment two of chip authentication method provided by the embodiment of the present invention
Schematic diagram, as shown in Fig. 2, this method includes the following steps：
S201 receives the instruction that printer is sent.
S202 identifies whether the instruction received is certification instruction.
Specifically, certification instruction includes appointment codes, appointment codes are the program compiled formats according to certification consumable chip
It is compiled.
During a concrete implementation, it can also include but not limited in certification instruction：Order, length, data and
At least one of verification.
S203, if identifying, the instruction received is instructed for certification, is run appointment codes, is obtained operation result.
Operation result is returned to printer by S204, in order to which printer is according to operation result, whether determines consumable chip
For certification consumable chip.
Specifically, due between printer and consumable chip there is also the possibility for thering are other data to interact, consumption
Material chip after the instruction for receiving printer transmission needs that these instructions are identified, to determine the finger newly received
Whether enable is certification instruction.The embodiment of the present invention identifies the specific implementation of instruction without especially limiting consumable chip
It is fixed.
For example, consumable chip may determine that in the instruction received whether include specify information, received if recognizing
Instruction in include specify information, it is certification instruction to determine that the instruction that receives；It is on the contrary, it is determined that the instruction received is not
It is certification instruction.
During a concrete implementation, specify information can be appointment codes.
Alternatively, in another example, consumable chip may determine that in the instruction received whether carry designated identification, if recognizing
Designated identification is carried in the instruction received, determines that the instruction received is instructed for certification；It is on the contrary, it is determined that receive
Instruction is not certification instruction.
During another concrete implementation, designated identification can be the command information specified.At this point, consumable chip is first
First the command information in the instruction that receives is identified, if this command information is specified command information, it is possible to determine
The instruction received is instructed for certification.
It is understood that both the above citing be only to illustrate consumable chip how to identify the instruction received whether be
Certification instructs, and in practical applications, which can also have other realization methods, the embodiment of the present invention to this without
It is particularly limited to.
It should be noted that the finger in the certification instruction that the program compiled format in consumable chip is received with consumable chip
When determining that program compiled format is consistent used in code, consumable chip can correctly run this section of appointment codes.
That is, the specified generation in the certification instruction that the program compiled format in certification consumable chip is received with consumable chip
Program compiled format used in code is consistent；But the program compiled format in the consumable chip of non-authentication connects with consumable chip
Program compiled format used in appointment codes in the certification instruction received is not necessarily the same.
Also, the embodiment of the present invention to the program compiled format in consumable chip without being particularly limited to, for example, program compile
Form is translated to can include but is not limited to：The use of code format, register cannot cover, storehouse must balance.
In the embodiment of the present invention, it is contemplated that the instruction that consumable chip receives may pass through data processing, therefore, at one
During concrete implementation, whether consumable chip can also further identify the instruction received by data processing, if identification
Go out the instruction received by data processing, data processing method is just further identified, then, according to the number specified received
According to processing mode, inverse processing is carried out to the instruction.If alternatively, identify that the instruction received without data processing, is not required to
Inverse processing is carried out to the instruction received.
For example, if encryption is passed through in the instruction received, after the encryption mode is recognized, to the finger received
Order is decrypted.
Alternatively, in another example, if the instruction received is handled through overcompression, after the compression processing mode is recognized, docking
The instruction received unzips it processing.
It should be noted that consumable chip can upon receipt of the instructions just immediately be made whether the instruction received
The step of whether instruction received is certification instruction identified in identification and then execution S202 by data processing；Or
Person, consumable chip can also be identified in S202 is performed after the step of whether instruction received is certification instruction, if warp
Cross the operating procedure in the identification of data processing and then execution S203.
Specifically, after consumable chip determines the instruction received for certification instruction, it is necessary to run this certification instruction
The appointment codes of middle carrying, the process may comprise steps of：
Specified address is written into appointment codes；
Obtain the pending data indicated by appointment codes；
Operation is stored in the program of specified address, handles pending data, obtains operation result.
Specifically, specified address can be preset according to actual needs, the embodiment of the present invention is to this without especially limiting
It is fixed.During a concrete implementation, appointment codes can be written to the data buffer area in consumable chip.
The instruction information for pending data is carried in the embodiment of the present invention, in appointment codes.Therefore, refer in operation
During determining code, need to obtain the pending data indicated by this appointment codes.
Specifically, it can include but is not limited to following two situations at this time：
The first, pending information is stored in the designated storage location of consumable chip.At this point, it is only needed in appointment codes
The designated storage location of pending information is indicated to consumable chip.In this way, consumable chip is running this section of appointment codes
When, the corresponding program of appointment codes of write-in can be utilized, these pending datas is handled, obtains operation result.
Second, pending information is carried in certification instruction.At this point, letter to be handled is not stored in consumable chip
Breath.In this way, consumable chip when running this section of appointment codes, extracts the pending data in certification instruction, and then, using writing
The corresponding program of appointment codes entered handles pending data, obtains operation result.
For more specific description this programme, the embodiment of the present invention provides consumable chip under a kind of specific application scenarios
Perform the realization process of the chip authentication method.
Specifically, if the instruction that printer is sent to consumable chip includes the following contents：
So, consumable chip is first identified the check information in instruction, judges to verify after this instruction is received
Whether information is correct.
If it is correct to detect check information, just according to the command information included in the instruction, the finger received is judged
Whether enable is certification instruction.Alternatively, such as detecting that check information is incorrect, then subsequent step is no longer performed, terminate flow.
If according to the command information in the instruction received, determine that the instruction is instructed for certification, then further judge that this is recognized
Whether card instruction passes through data processing.If according to the command information in the instruction received, it is not certification instruction to determine the instruction,
Then no longer perform the follow-up process of this programme.
If judging, certification instruction have passed through data processing, identifies data processing method, and perform inverse processing, obtains
Certification instruction after inverse processing；If alternatively, certification instruction is skipped the step, is directly performed without data processing
Next step.
The appointment codes (code A) carried during certification is instructed are stored to the finger in the data buffer area of consumable chip
Address is determined, for example, in the address that the 0x200800 being stored in data buffer area starts.
Then, consumable chip gets data B and data C as pending data, and data B is stored data buffer area respectively
In the addresses that start of 0x2001C0 in, data C is stored in the address that the 0x2001D0 in data buffer area starts.
Later, consumable chip execution is stored in this section of code A of 0x200800.Assuming that code A instructions are meant that and incite somebody to action
Data B and data C carries out data processing using algorithm D, obtains data G.So, journey of the consumable chip according to indicated by code A
Sequence carries out above-mentioned processing, and obtained operation result is exactly data G.
In this way, if consumable chip is not certification consumable chip, consumable chip just has no ability to perform code A, also would not
The programmed algorithm indicated by code A is got, it is data G that also can not just obtain correct operation result, then, consumable chip returns
It is also impossible to be correct back to the operation result of printer.
In the embodiment of the present invention, consumable chip, can be directly obtained operation when returning to operation result to printer
As a result printer is returned to, alternatively, after designated treatment can also be carried out to operation result, then the operation after designated treatment
As a result printer is returned to, the embodiment of the present invention is to this without being particularly limited to.
Still it is illustrated by taking above-mentioned realization method as an example.
During a concrete implementation, the data that consumable chip returns to printer can include：
90 6C DF 7B 7B, 25 04D9 0A E8 0B, 29 87 2F of 57FC // data G
D4 95 // verification
Alternatively, during another concrete implementation, the data that consumable chip returns to printer can include：
90 6C DF 7B 7B // data K
D4 95 // verification
Wherein, data K is through overcompression treated data G.
It should be noted that chip authentication method provided in an embodiment of the present invention is implemented in consumable chip, consumable chip
It can be located in consumption material box.During concrete implementation, consumption material box can be print cartridge.
