Description

[Technical field]

[0001] The invention belongs to the field of printing, and in particular relates to an anti-counterfeiting verification method and system for consumables. [Background technology]

[0002] The printing equipment and consumables market is a mixed bag. Counterfeiting not only affects the user experience and infringes on consumer rights, but also occupies the market space of genuine manufacturers and destroys the healthy competition order of the industry. Therefore, it is imperative to implement encrypted anti-counterfeiting identification technology in the printing field.

[0003] At present, the anti-counterfeiting verification of consumables is generally performed by obtaining identification information by a printing device reading a consumable chip pre-attached to a consumable reel, and then comparing and verifying the information with the key answer to determine the authenticity. This method overly relies on the confidentiality of the consumable identification information and the verification answer. If the above information is known in advance and written into the verification device, the consumables will be easily cracked or copied in large quantities. Based on this, in order to address the defects of the prior art, the present invention provides a method for performing anti-counterfeiting verification on consumables by calculating the rotation speed of a motor and detecting whether a preset mark exists in a preset area of ​​the consumable at a preset time. This method can increase the difficulty of technical cracking and enhance the effect of anti-counterfeiting identification. [Summary of the invention]

[0004] In view of this, the purpose of the embodiments of the present invention is to overcome the defects of the prior art that it is easy to be cracked or copied in large quantities, and to provide a method for anti-counterfeiting verification of consumables, thereby increasing the difficulty of technical cracking and enhancing the effect of anti-counterfeiting identification.

[0005] An embodiment of the present invention provides an anti-counterfeiting verification method for consumables, comprising the following steps:

[0006] S1: Get the consumable serial number X and the printing device serial number Y;

[0007] S2: Call the preset first algorithm to calculate the motor rotation angular velocity θ=k(X, Y), and call the preset second algorithm h(X, Y) to calculate the preset identifier N:

[0008] S3: The printing device drives the motor to work for t time to detect whether the actual mark N' in the preset area of ​​the consumable is equal to the preset mark N: if they are equal, the consumable anti-counterfeiting verification passes; otherwise, the consumable anti-counterfeiting verification fails.

[0009] Furthermore, the preset time t is pre-stored in a memory of the printing device.

[0010] Furthermore, after executing step S1 and before executing step S2, a preset third algorithm is called to decompose the consumable serial number X into a first consumable verification sequence x1 and a second consumable verification sequence x2, and one of the consumable verification sequences is randomly selected for data combination with the printing device serial number, and it is verified that there is a preset mapping relationship between the data combination and the unselected consumable verification sequence.

[0011] Furthermore, the printing device or the cloud server verifies that there is a preset mapping relationship between the data combination and the unselected consumables verification sequence.

[0012] Furthermore, when the cloud server verifies that there is a preset mapping relationship between the data combination and an unselected consumable verification sequence, the printing device uses the printing device serial number as a key to encrypt the data combination, and sends the printing device serial number and the encrypted data combination to the cloud server respectively.

[0013] An embodiment of the present invention also provides a consumable anti-counterfeiting verification system, including an RFID reader / writer, a processor and a memory, wherein the RFID reader / writer is used to identify the consumable serial number, the processor is used to receive, process and transmit data information, and the memory stores a computer program, and when the computer program is executed by the processor, the consumable anti-counterfeiting verification method described in the above claims is implemented.

Obviously, the described embodiment is only a part of the embodiment of the present invention, not all embodiments.

The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0023] Embodiment 1:

[0024] See also Figure 1 As shown, the first embodiment of the present invention provides an anti-counterfeiting verification method for a printing device and consumables, specifically, comprising at least the following steps:

[0025] S1: Get the consumable serial number X and the printing device serial number Y.

[0026] In this embodiment, the consumable serial number and the printing device serial number are characters used for anti-counterfeiting verification, and can be randomly generated characters with a predetermined format or characters with preset fixed content. The method for obtaining the printing device serial number can be any feasible method.

[0027] In a specific embodiment, the consumable serial number can be obtained through a printing device, or through a smart phone, PC, tablet computer or other intelligent information terminal with interactive and information processing capabilities, which is not limited by the present invention. The consumable serial number is obtained through an intelligent information terminal, which is connected to the printing device by wired or wireless means to achieve communication with the printing device, thereby guiding the execution of the printing process.

[0028] The serial number of the printing device can be directly set at the factory, directly read from the device and its manual, or obtained through an intelligent information terminal.

[0029] S2: calling a preset first algorithm to calculate the motor rotation angular velocity θ=k(X, Y), and calling a preset second algorithm h(X, Y) to calculate a preset identifier N;

[0030] S3: The printing device drives the motor to work for t time to detect whether the actual mark N' in the preset area of ​​the consumable is equal to the preset mark N: if they are equal, the consumable anti-counterfeiting verification passes; otherwise, the consumable anti-counterfeiting verification fails.

[0031] In this embodiment, the motor rotation angular velocity and the number of pre-set marks on the consumables are calculated with the consumables serial number and the printing device serial number as variable information. The mark can be a dot or a fluorescent mark, can be one or several, can be set in the center of a preset area, or can occupy the entire space of the preset area. The embodiment of the present invention does not specifically limit the position, size, number, form, etc. of the preset mark.

[0032] The printing device drives the motor to work for t time to detect whether there is a preset mark in the preset area of ​​the consumable. If it is consistent with the preset mark, the consumable anti-counterfeiting verification passes; if it is different from the preset mark, the consumable anti-counterfeiting verification fails.

[0033] Preferably, the preset time t is pre-stored in a memory of the printing device.

[0034] The preset time t is determined by the preset identification position and the motor rotation angular velocity, and the motor rotation angular velocity is determined by the consumable serial number and the printing device serial number. The preset time t is different for different consumables and printing devices, so it is predetermined and stored in the printing device memory during factory settings.

[0035] In order to further increase the difficulty of cracking, an implementation scheme is also provided in the embodiment of the present invention: after executing step S1 and before executing step S2, a preset third algorithm is called to decompose the consumable serial number X into a first consumable verification sequence x1 and a second consumable verification sequence x2, and a consumable verification sequence is randomly selected to perform data combination with the printing device serial number, and it is verified that there is a preset mapping relationship between the data combination and the unselected consumable verification sequence.

[0036] In this embodiment, the preset third algorithm is an algorithm for randomly decomposing the consumable serial number and the printing device serial number, such as an odd-even combination, etc., which is not limited in the present invention.

[0037] In a specific embodiment, the consumable serial number is set to a 6-bit string containing 123456, the first algorithm is preset to be an odd-even combination method, the first consumable verification sequence and the second consumable verification sequence are 3-bit strings, the odd bits of the consumable serial number are stored in the first consumable verification sequence in this way, and x1 is 135, and the even bits of the consumable serial number are stored in the second consumable verification sequence in this way, and x2 is 246. Different from the prior art, the first verification sequence and the second verification sequence in the embodiment of the present invention are not all stored in the storage unit in advance, nor are they obtained by a simple addition and subtraction algorithm, but are decomposed by a preset algorithm and then written.

[0038] After the consumables serial number is algorithmically decomposed, any consumables verification sequence and printing device sequence are randomly selected for data combination. In this embodiment, the first consumables verification sequence x1 and the printing device serial number Y can be selected as a data combination, or the second consumables verification sequence x2 and the printing device serial number Y can be selected as a data combination, which is not limited in the present invention.

[0039] Furthermore, it is verified whether there is a preset mapping relationship between the data combination and the unselected consumables verification sequence. In a specific embodiment, the first consumables verification sequence x1 and the printing device serial number Y are set as a data combination, and the preset verification algorithm f is called to verify whether the unselected second consumables verification sequence x2 has a preset mapping relationship with f(x1, Y). If so, proceed to the next step, otherwise the printing device and consumables anti-counterfeiting verification fails.

[0040] Preferably, verification that the data combination has a preset mapping relationship with the unselected consumables verification sequence can be performed on the printing device or on the cloud server. If the cloud server verifies that the data combination has a preset mapping relationship with the unselected consumables verification sequence, the printing device is connected to the printing application on the intelligent information terminal through a short-range communication method, and the intelligent information terminal is connected to the cloud server through a long-range communication method, thereby realizing communication between the printing device and the cloud server.

[0041] Preferably, when the cloud server verifies that there is a preset mapping relationship between the data combination and the unselected consumable verification sequence, the printing device uses the printing device serial number as a key to encrypt the data combination, and sends the printing device serial number and the encrypted data combination to the cloud server respectively.

[0042] In a specific embodiment, if the cloud server verifies that there is a preset mapping relationship between the data combination and the unselected consumables verification sequence, the printing device sends the encrypted data combination f(x1, Y) and the key printing device serial number Y to the cloud server. The cloud server decrypts the ciphertext, identifies the data combination from the decrypted information, and uses the preset verification algorithm f to verify whether x2 has a preset mapping relationship with f(x1, Y). If so, the verification is successful, otherwise the anti-counterfeiting verification of the printing device and the consumables fails.
