DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0012] The terms "first", "second", etc. in this specification and claims are used to distinguish similar objects, and are not used to describe a particular order or precedence. It should be understood that the terms used in this way can be interchanged where appropriate so that the embodiments of the present application are implemented in a sequence other than those illustrated or described herein. In addition, "and / or" in this specification and claims means at least one of the connected objects, and the character " / " generally means that the objects associated with each other are in an "or" relationship.

[0013] As mentioned above, although the basic information of different consumable chips is slightly different, they cannot be used interchangeably, resulting in a waste of resources.

[0014] The applicant studied the basic information of a large number of consumable chips and found that the basic information of consumable chips applicable to different printing devices is slightly different. If the basic information of consumable chip A applicable to printing device A is modified to the basic information of consumable chip B applicable to printing device B, although in theory consumable chip A can be applicable to printing device B, it was found during actual testing that the modified consumable chip A cannot pass the certification of the printing device.

[0015] The applicant further discovered that the reason why printing consumables B could not pass the authentication was that before using consumable chip A, printing device B would authenticate consumable chip A, that is, it required the basic information of consumable chip A to match the verification information; since the verification information of consumable chip A was encrypted based on its original basic information, the modified basic information could not match the verification information, which in turn caused consumable chip A to fail the authentication of the printing device.

[0016] The applicant further studied the authentication logic of the printing device and found that the authentication logic of the printing device is usually as follows: the printing device obtains the basic information and verification information of the consumable chip based on the configuration table of the consumable chip. If the verification information is not found, the printing device will default to the absence of such verification information, and the authentication will be successful.

[0017] Based on the above research findings, an embodiment of the present application proposes a consumable chip authentication method, which adopts the following inventive concept: by modifying the basic information of consumable chip B applicable to printing device B as the basic information of consumable chip A, consumable chip A is theoretically applicable to printing device B; on this basis, to ensure that consumable chip A can pass the authentication of printing device B, the configuration information of the verification information in the configuration table of consumable chip A is hidden, so that printing device B cannot determine that the verification information does not exist based on the configuration information of the verification information obtained from the configuration table, and determines that the authentication of consumable chip A is successful, thereby achieving that the basic information of the same consumable chip can be reused for other consumable chips, and ensuring that other consumable chips can pass the authentication on the printing device, thereby improving resource utilization.

[0018] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0019] Please refer to Figure 1 , is a flow chart of a consumable chip authentication method provided by an embodiment of the present application, the method is applied to a first consumable chip. Figure 1 As shown, the method comprises the following steps: S102, receiving an authentication instruction from a first printing device for a first consumable chip.

[0020] The first printing device may be a printing device to which the first consumable chip is not applicable, for example, consumable chip A is applicable to printing device A, and printing device B is the first printing device for consumable chip A. Of course, the first printing device may also be a printing device to which the first consumable chip is applicable.

[0021] As an example, the printing device to which the first consumable chip is applicable is a printing device of the same brand and series as the first printing device but in a different region.

[0022] S104: In response to the authentication instruction, return the target configuration table to the first printing device.

[0023] The target configuration table includes configuration information of target basic information of the first consumable chip, and the target configuration table does not include configuration information of verification information of the first consumable chip. The target basic information is obtained based on the original basic information of the second consumable chip. The second consumable chip is suitable for the first printing device.

[0024] Each consumable chip has corresponding original basic information and verification information. The original basic information of the consumable chip may include but is not limited to the serial number and the attributes of the printing device to which the consumable chip is applicable. Among them, the attributes of the printing device may, for example, include but are not limited to: the region, brand, series, capacity, color, etc. of the printing device. The region of the printing device generally refers to a large region, such as Asia, Europe, North America, Asia Pacific, etc., which is the region announced when the printing device is released. The verification information of the consumable chip is encrypted based on the original basic information of the consumable chip, and is used by the printing device to authenticate the consumable chip.

[0025] In an embodiment of the present application, since the second consumable chip is suitable for the first printing device, in order to make the first consumable chip suitable for the first printing device, the target basic information of the first consumable chip can be obtained based on the original basic information of the second consumable chip. For example, the original basic information of the second consumable chip is used as the target basic information of the first consumable chip to replace the original basic information of the first consumable chip, or the original basic information of the second consumable chip is written into the storage location where the original basic information of the first consumable chip is located, so that the target basic information of the first consumable chip includes the original basic information of the first consumable chip and the original basic information of the second consumable chip.

[0026] Each consumable chip also has a corresponding original configuration table for recording the data stored in the consumable chip and the configuration information of the data. The configuration information of the data may include, for example, but is not limited to, the storage location and length of the data. It can be seen that the original configuration table of the consumable chip can also be considered as an index table, which is equivalent to the directory of the consumable chip. As an example, the original configuration table of the consumable chip includes the index number, storage location and length of each data stored in the consumable chip. In this way, the required data can be quickly and accurately queried from the consumable chip according to the original configuration table.

[0027] Normally, after receiving the authentication instruction sent by the printing device, the consumable chip will return the original configuration table to the printing device. The original configuration table includes the configuration information of the original basic information of the consumable chip and the configuration information of the verification information. Exemplarily, the index number of the configuration information of the verification information in the original configuration table is usually fixed. For example, the original configuration table includes N rows of data, and the index numbers are 0, 1, 2, 3, ..., N, respectively, wherein the data corresponding to the index number N is the configuration information of the verification information. The printing device can determine that the verification information is stored in the consumable chip by reading the data with the index number N. In this case, the printing device can read the original basic information and the verification information from the consumable chip according to the original configuration table, and authenticate the consumable chip based on these two information; if the two information match, such as the verification information is consistent with the original basic information after decryption, etc., then it is determined that the authentication of the consumable chip is successful; if the two information do not match, such as the verification information is inconsistent with the original basic information after decryption, etc., then it is determined that the authentication of the consumable chip has failed.

[0028] However, in the embodiment of the present application, since the target basic information of the first consumable chip is different from the original basic information and cannot match the verification information of the first consumable chip, if the original configuration table is returned to the first printing device, the first consumable chip will fail to pass the authentication of the first printing device. In view of this, in the embodiment of the present application, the first consumable chip returns the target configuration table of the configuration information that does not contain the verification information to the first printing device, which will cause the first printing device to assume that the verification information does not exist because it cannot query the verification information, and then determine that the authentication of the first consumable chip is successful, so that the original basic information of each consumable chip can be reused for the consumable chips corresponding to other printing devices, and ensure that the consumable chip that reuses the original basic information can successfully pass the authentication of the printing device, which is conducive to improving resource utilization.

[0029] In the embodiment of the present application, the target basic information and the target configuration table of the first consumable chip can be obtained through various appropriate methods, which are not limited in the embodiment of the present application.

[0030] In one embodiment, if Figure 2 The above-mentioned step further includes the following steps before S104: S202, obtaining an original configuration table of the first consumable chip.

[0031] The original configuration table includes configuration information of original basic information and configuration information of verification information of the first consumable chip.

[0032] S204: Obtain target basic information of the first consumable chip based on the configuration information of the original basic information in the original configuration table and the original basic information of the second consumable chip.

[0033] As an example, based on the configuration information of the original basic information of the first consumable chip, the storage location of the original basic information of the first consumable chip is determined; and the original basic information of the second consumable chip is written into the storage location as the target basic information.

[0034] In this way, the first consumable chip can be successfully authenticated when it is inserted into the originally applicable printing device or the first printing device.

[0035] For example, suppose the first consumable chip is consumable chip A, which is applicable to printing device A, and the second consumable chip is consumable chip B, and the first printing device applicable to it is printing device B. According to the configuration information of the original basic information of consumable chip A, it is determined that the original basic information of consumable chip A is stored in storage area A of consumable chip A; further, the original basic information of consumable chip B is written into storage area A as the target basic information. In this way, storage area A contains the original basic information of consumable chip A and the original basic information of consumable chip B, so that consumable chip A can be successfully authenticated when it enters printing device A or printing device B, thereby realizing that the original basic information of consumable chip B is universal on printing device A and printing device B.

[0036] As another example, based on the configuration information of the original basic information of the first consumable chip, the storage location of the original basic information of the first consumable chip is determined; the original basic information of the first consumable chip is read from the storage location; the difference information between the original basic information of the first consumable chip and the original basic information of the second consumable chip is determined; the original basic information of the first consumable chip is modified based on the difference information to obtain the target basic information of the first consumable chip.

[0037] For example, assume that the first consumable chip is consumable chip A, and the second consumable chip is consumable chip B. According to the configuration information of the original basic information of consumable chip A, determine that the original basic information of consumable chip A is stored in storage area A of consumable chip A; then, read the original basic information of consumable chip A from storage area A, and compare the original basic information with the original basic information of the second consumable chip to obtain the difference information between the two. Assuming that consumable chip A and consumable chip B are different in the area of ​​the applicable printing device, then on the basis of the original basic information of consumable chip A, the area of ​​the printing device applicable to consumable chip A is modified to the area of ​​the printing device applicable to consumable chip B, and the modified original basic information is used as the target basic information of consumable chip A. In this way, it can be ensured that consumable chip A can be successfully authenticated when it enters the printing device applicable to printing device B.

[0038] In this method, the difference in original basic information between the first consumable chip and the second consumable chip is used to modify the original basic information of the first consumable chip, which can not only reduce the amount of calculation and improve calculation efficiency, but also save the storage space of the first consumable chip.

[0039] S206, hiding the configuration information of the verification information in the original configuration table to obtain a target configuration table.

[0040] As an example, the configuration information of the verification information is deleted from the original configuration table to obtain the target configuration table. For example, the original configuration table of consumable chip A includes N rows of data, and the index numbers are 0, 1, 2, 3, ..., N, wherein the data corresponding to the index number N is the configuration information of the verification information. By performing a deletion operation on the Nth row of data, the configuration information of the verification information can be hidden, and a target configuration table containing N-1 rows of data is obtained, and the index numbers are 0, 1, 2, 3, ..., N-1. This method is efficient and convenient.

[0041] As another example, the configuration information of the verification information in the original configuration table is masked to obtain the target configuration table. For example, the original configuration table of consumable chip A includes N rows of data, and the index numbers are 0, 1, 2, 3, ..., N, respectively, where the data corresponding to index number N is the configuration information of the verification information. By replacing the Nth row of data with special characters (such as null, *), the configuration information of the verification information can be hidden to obtain the target configuration table. In this case, the target configuration table still contains N rows of data, but the Nth row of data has been masked, which also makes it impossible for the printing device to obtain the configuration information of the verification information and judge that the verification information does not exist, thereby determining that the authentication of consumable chip A is successful.

[0042] In the above embodiment, the target configuration table is obtained by modifying the original configuration table of the first consumable chip, and the target basic information of the first consumable chip is obtained based on the configuration information of the original basic information in the original configuration table and the original basic information of the second consumable chip, which has small calculation amount, is convenient and efficient.

[0043] In another embodiment, the basic information of the second consumable chip can be used as the target basic information of the first consumable chip and stored in the first consumable chip, and based on the storage location and length of the target basic information, as well as the original configuration information of other data in the first consumable chip except the verification information, a configuration table can be regenerated as the target configuration table.

[0044] The embodiment of the present application shows some implementation methods of obtaining the target basic information and target configuration table of the first consumable chip. Of course, it should be understood that the target basic information and target configuration table of the first consumable chip can also be obtained by other methods.

[0045] In another implementation of the present application, after obtaining the target basic information and target configuration table of the first consumable chip, the method may further include: writing the target basic information and target configuration table of the first consumable chip into the first consumable chip. In this way, the first consumable chip can be successfully authenticated when it is inserted into the first printing device, which greatly improves the versatility of the consumable chip and its original basic information.

[0046] Through the consumable chip authentication method provided in the embodiment of the present application, the original basic information of any consumable chip can be made universal on the consumable chips corresponding to printing devices of other brands, other regions, and other series, and it can be ensured that the consumable chips that reuse the original basic information can pass the authentication of the printing device, which greatly improves the universality of the consumable chips and their original basic information, thereby improving resource utilization.

[0047] As an example, the printing device to which the first consumable chip is applicable is a printing device of the same brand, same series, but in different regions as the first printing device. For example, consumable chip A (the first consumable chip) is applicable to printing device A of the A series released by brand A in region A, and printing device B (the first printing device) is a printing device of the A series released by brand A in region B. By generating the target basic information of consumable chip A based on the original basic information of consumable chip B (the second consumable chip) applicable to printing device B, consumable chip A can be universally used on printing device B of the same brand, same series, but in different regions.

[0048] As another example, the printing device to which the first consumable chip is applicable is a printing device of the same brand, same region, and different series as the first printing device. For example, consumable chip A (the first consumable chip) is applicable to printing device A of the A series released by brand A in region A, and printing device B (the first printing device) is a printing device of the B series released by brand A in region A. By generating the target basic information of consumable chip A based on the original basic information of consumable chip B (the second consumable chip) applicable to printing device B, consumable chip A can be used universally on printing device B of the same brand, same region, and different series.

[0049] As another example, the printing device to which the first consumable chip is applicable is a printing device of the same brand, but in different regions and series as the first printing device. For example, consumable chip A (the first consumable chip) is applicable to printing device A of the A series released by brand A in region A, and printing device B (the first printing device) is a printing device of the B series released by brand A in region B. By generating the target basic information of consumable chip A based on the original basic information of consumable chip B (the second consumable chip) applicable to printing device B, consumable chip A can be used universally on printing device B of the same brand, but in different regions and series.

[0050] As another example, the printing device to which the first consumable chip is applicable is a printing device of a different brand, region, or series from the first printing device. For example, consumable chip A (the first consumable chip) is applicable to printing device A of the A series released by brand A in region A, and printing device B (the first printing device) is a printing device of the B series released by brand B in region B. By generating the target basic information of consumable chip A based on the original basic information of consumable chip B (the second consumable chip) applicable to printing device B, consumable chip A can be universally used on printing devices B of different brands, regions, and series.

[0051] One or more embodiments of the present application provide a consumable chip authentication method, which modifies the basic information of the second consumable chip applicable to the first printing device and uses it as the basic information of the first consumable chip, so that the first consumable chip is theoretically applicable to the first printing device; on this basis, to ensure that the first consumable chip can pass the authentication of the first printing device, the configuration information of the verification information in the configuration table of the first consumable chip is hidden, so that the first printing device cannot determine that the verification information does not exist based on the configuration information of the verification information obtained from the configuration table, and determines that the authentication of the first consumable chip is successful, thereby achieving that the original basic information of each consumable chip can be reused for the consumable chips corresponding to other printing devices, and ensuring that the consumable chip that reuses the original basic information can successfully pass the authentication of the printing device, thereby improving resource utilization.

[0052] Please refer to Figure 3 , is a flow chart of a consumable chip authentication method provided by an embodiment of the present application, and the method is applied to a printing device. Figure 3 As shown, the method comprises the following steps: S302: Send an authentication instruction to the first consumable chip.

[0053] Exemplarily, the printing device may send an authentication instruction to the first consumable chip when the first consumable chip is loaded into the machine.

[0054] S304, receiving the configuration table returned by the first consumable chip.

[0055] S306: If the received configuration table is the target configuration table, it is determined that the first consumable chip is authenticated successfully.

[0056] The target configuration table includes configuration information of target basic information of the first consumable chip, and the target configuration table does not include configuration information of verification information of the first consumable chip. The target basic information is obtained based on the original basic information of the second consumable chip of the printing device.

[0057] Since the target configuration table does not include configuration information of the verification information of the first consumable chip, the printing device cannot query the verification information according to the target configuration table, and determines that the verification information does not exist, and then determines that the first consumable chip is authenticated successfully and performs subsequent printing operations.

[0058] As an example, the target configuration table includes index numbers and configuration information corresponding to the index numbers, and the index numbers in the target configuration table include index numbers for representing target basic information of the first consumable chip, and do not include index numbers for representing verification information. In practical applications, the index numbers for representing target basic information and the index numbers for representing verification information are fixed.

[0059] The configuration information corresponding to the index number in the target configuration table includes at least one of the following information: the storage location of the information represented by the index number in the first consumable chip, and the length of the information represented by the index number.

[0060] In this case, the above S306 includes: reading the index number used to represent the verification information from the received configuration table; if the index number used to represent the verification information fails to be read, it is determined that the configuration table does not include configuration information of the verification information, that is, the configuration table is the target configuration table, and then it is determined that the authentication of the first consumable chip is successful.

[0061] In another embodiment, after the above S304, it also includes: if the received configuration table is a target configuration table, reading the configuration information of the target basic information of the first consumable chip from the target configuration table; based on the configuration information of the target basic information, reading the target basic information from the first consumable chip, the target basic information is used to perform a printing operation after determining that the first consumable chip has been authenticated successfully.

[0062] In another embodiment, Figure 4 As shown, after the above S306, it also includes: S308: If the received configuration table is an original configuration table, read the configuration information of the original basic information and the configuration information of the verification information of the first consumable chip from the original configuration table.

[0063] If the index number used to represent the verification information in the received configuration table is read successfully, it is determined that the configuration information in the configuration table includes the verification information, that is, the configuration table is the original configuration table, and then the configuration information of the verification information is read from the original configuration table based on the index number, and the configuration information of the original basic information is read from the original configuration table based on the index number used to represent the original basic information of the first consumable chip.

[0064] S310 , based on the configuration information of the original basic information of the first consumable chip, read the original basic information of the first consumable chip from the first consumable chip.

[0065] As an example, the configuration information of the original basic information includes the storage location and length of the original basic information in the first consumable chip, and based on these two pieces of information, the original basic information can be read from the first consumable chip.

[0066] S312, reading verification information from the first consumable chip based on configuration information of the verification information.

[0067] As an example, the configuration information of the verification information includes the storage location and length of the verification information in the first consumable chip, and based on these two pieces of information, the verification information can be read from the first consumable chip.

[0068] S314, matching the verification information with the original basic information of the first consumable chip.

[0069] As an example, the original basic information may be encrypted, and the ciphertext of the original basic information may be compared with the verification information. If the two are consistent, it is determined that the verification information matches the original basic information.

[0070] S316: Based on the matching result, determine whether the first consumable chip is authenticated successfully.

[0071] If the matching result indicates a successful match, it is determined that the first consumable chip is authenticated successfully; if the matching result indicates a failed match, it is determined that the first consumable chip is authenticated failed.

[0072] To facilitate understanding of the consumable chip authentication method provided in the embodiment of the present application, the consumable chip authentication method provided in the embodiment of the present application is described below using a specific scenario as an example.

[0073] Consumable chip A is applicable to printing device A, and consumable chip B is applicable to printing device B, wherein printing device A and printing device B may be printing devices of the same brand, same series, and different regions, or printing devices of the same brand, same region, and different series, or printing devices of the same brand, different regions, and different series, or printing devices of different brands, different regions, and different series.

[0074] In one embodiment, after the consumable chip A enters the printing device, the printing device A sends an authentication instruction to the consumable chip A. In response to the authentication instruction, the consumable chip A returns the original configuration table to the printing device A. The printing device A reads the original basic information from the consumable chip A according to the configuration information of the original basic information in the original configuration table, and reads the verification information from the consumable chip according to the configuration information of the verification information in the original configuration table. Then, the printing device A authenticates the consumable chip A based on the original basic information and the verification information; if the original basic information and the verification information match, it is determined that the consumable chip A is successfully authenticated, and then the subsequent printing operation is performed; if the original basic information and the verification information do not match, it is determined that the consumable chip A fails to be authenticated, and then an error prompt message is output.

[0075] In one embodiment, in order to reuse the original basic information of consumable chip B for consumable chip A and ensure that consumable chip A can pass authentication on printing device B, first, consumable chip A obtains its own original configuration table A, reads original basic information A according to the configuration information of original basic information A in original configuration table A, and then generates target basic information according to original basic information A and original basic information of consumable chip B. In addition, consumable chip A also hides the configuration information of verification information in original configuration table A to obtain the target configuration table.

[0076] After consumable chip A is inserted into printing device B, printing device B sends an authentication instruction to consumable chip A. In response to the authentication instruction, consumable chip A returns the target configuration table to printing device B. Since the configuration information of the verification information in the target configuration table is hidden, printing device B cannot obtain the configuration information, determines that the verification information does not exist, and then determines that the authentication of consumable chip A is successful, and performs subsequent printing operations. In this way, the original basic information of consumable chip B can be reused for consumable chip A, and it is ensured that consumable chip A can pass the authentication on printing device B.

[0077] The above is a description of a specific embodiment of the specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the embodiments and still achieve the desired results.
