[0060] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0061] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0062] Please refer to Figure 1, which is a flowchart of an anti-counterfeiting method for atomizers provided in an embodiment of this application. The anti-counterfeiting method for atomizers is applied to an atomizer generating device, which includes a main body and an atomizer with an electronic tag. The atomizer has a locked state and an unlocked state. In the locked state, the atomizer is prohibited from generating atomizers, and in the unlocked state, it is allowed to generate atomizers.
[0063] When the atomizer is housed in the main unit, the main unit can communicate wirelessly with the electronic tag, which stores a unique identification code and a preset access password generated based on the unique identification code.
[0064] As shown in Figure 1, the anti-counterfeiting method for atomizers includes steps S11-S14, as detailed below:
[0065] Step S11: When the atomizer is inserted into the main body, read the unique identification code.
[0066] The unique identification code is stored in the unencrypted storage area of the electronic tag.
[0067] It is worth noting that the unique identification code includes at least the manufacturer code. The unique identification code written into the electronic tag cannot be changed, and the manufacturer of the atomizer can be identified through the unique identification code.
[0068] For example, the unique identifier is 7 bytes of data. Correspondingly, the preset access password generated based on the unique identifier is 4 bytes of data. It can be understood that the lengths of the unique identifier and the preset access password can be determined according to the actual scheme design.
[0069] Compared to writing a preset access password into each electronic tag, in this embodiment, the preset access password of the electronic tag is generated based on a unique identification code. Therefore, each electronic tag has a preset access password, which makes the preset access password impossible to crack in batches, thus improving security.
[0070] In one embodiment, as shown in FIG2, step S11 is implemented through steps S111-S113, as follows:
[0071] Step S111: Check if the atomizer is inserted into the main body.
[0072] Step S112: If yes, then send a wireless signal to the electronic tag to establish a wireless communication connection with the electronic tag.
[0073] Step S113: Send a read request message to the electronic tag to read the unique identification code.
[0074] A typical device includes a smoking device. When the atomizer is inserted into the device, the device establishes a wireless communication connection with the electronic tag. Since the unique identification code is stored in the unencrypted storage area of the electronic tag, the device can read the unique identification code of the electronic tag.
[0075] Step S12: Generate the current access password based on the unique identification code.
[0076] In one embodiment, the current access password and the preset access password are generated using the same password generation rules.
[0077] Both the current access password and the preset access password are generated based on a unique identification code. For manufacturers, by using the same password generation rules for both the current and preset access passwords, the current and preset access passwords are consistent, thus switching the atomizer from a locked state to an unlocked state, or allowing the user to read the atomizer data from the electronic tag. On the one hand, this ensures that the user's atomizers and devices can be used normally. On the other hand, since other manufacturers are unaware of the password generation rules for the preset access password, the current access password generated based on the unique identification code will be different from the preset password, thus achieving the effect of anti-counterfeiting for the atomizer.
[0078] Optionally, the password generation rules include preset encryption algorithms and preset selection rules.
[0079] The preset encryption algorithm can be a combination of one or more existing encryption algorithms, such as a symmetric encryption algorithm, or it can be a custom calculation formula. It can be understood that the preset encryption algorithm and preset selection rules are pre-set according to the anti-counterfeiting requirements of the atomizer.
[0080] As shown in Figure 3, step S12 is implemented through steps S121-S122, as follows:
[0081] Step S121: Encrypt the unique identification code using a preset encryption algorithm to obtain ciphertext data.
[0082] For example, the encrypted data can be 4-16 bytes.
[0083] Step S122: Generate the current access password according to the preset selection rules and ciphertext data.
[0084] In theory, based on the uniqueness of the unique identifier, the ciphertext data obtained will be different from the current access password depending on the preset encryption algorithm.
[0085] Specifically, as shown in Figure 3, step S122 is implemented through steps S1221-S1222, as follows:
[0086] Step S1221: Determine the target byte according to the preset selection rules.
[0087] Step S1222: Select target bytes from the ciphertext data and combine them to form the current access password.
[0088] If the current access password is 4 bytes of data, and the ciphertext data is also 4 bytes of data, then the ciphertext data will be used as the current access password.
[0089] Assuming the current access password is 4 bytes of data, if the length of the ciphertext data is greater than 4 bytes, the target byte is determined according to a preset selection rule. This target byte is then selected from the ciphertext data and combined to form the current access password. In one example, the preset selection rule selects the first 4 bytes of the ciphertext data; these first 4 bytes are the target bytes, and the data selected from them is the current access password. In another example, the preset selection rule selects the first 4 bytes of the ciphertext data with odd-numbered sequences; these first 4 bytes are the target bytes, and the data selected from them is the current access password. In yet another example, the preset selection rule selects the 4 bytes with sequences "1, 2, 5, 7" from the ciphertext data; these 4 bytes with sequences "1, 2, 5, 7" are the target bytes, and the data selected from them is the current access password.
[0090] Step S13: Send a verification request to the electronic tag. The verification request includes the current access password.
[0091] In one example, the subject includes an RF transmitter that sends a verification request to the electronic tag, the verification request including the current access password.
[0092] Step S14: Receive the verification result information returned by the electronic tag, and based on the verification result information, change the atomizer from the locked state to the unlocked state, or keep it in the locked state. The verification result information is used to indicate whether the current access password and the preset access password are consistent.
[0093] The electronic tag receives the verification request information, compares the current access password with the preset access password, generates verification result information, and returns the verification result information to the subject. The subject receives the verification result information returned by the electronic tag, determines whether the verification is successful, and if so, switches the atomizer from locked to unlocked; otherwise, it keeps the atomizer locked. In one example, after switching the atomizer from locked to unlocked, an aerosol generating matrix is heated in response to the inhalation action to produce an aerosol.
[0094] The atomizer anti-counterfeiting method provided in this application generates a current access password based on a unique identification code, accesses an electronic tag using the current access password, and the electronic tag verifies whether the current access password is consistent with the preset access password generated based on the unique identification code. Based on the verification result information returned by the electronic tag, the atomizer is changed from a locked state to an unlocked state, or remains in a locked state, thereby achieving anti-counterfeiting of the atomizer.
[0095] Based on the above embodiments, the electronic tag also stores atomizer data. Both the preset access password and the atomizer data are stored in the encrypted storage area of the electronic tag. Referring to Figure 5, after receiving the verification result information returned by the electronic tag, the method further includes steps S151-S153, as follows:
[0096] Step S151: Determine whether the verification result information is a successful verification message. The verification result information includes successful verification information and failed verification information. Successful verification information is used to indicate that the current access password is consistent with the preset access password.
[0097] Step S152: If yes, read the atomizer data.
[0098] As shown in Figure 6, after step S151, the method further includes step S17, performing a write operation on the atomizer data.
[0099] After reading atomizer data or performing a write operation on atomizer data, the method further includes: stopping the transmission of wireless signals to the electronic tag, thereby shutting down the wireless communication connection between the subject and the electronic tag.
[0100] It is worth noting that after the electronic tag is powered on, the main body is allowed to read / write atomizer data.
[0101] The electronic tag itself has no power source. While the host device sends wireless signals to the electronic tag to establish a wireless communication connection, it simultaneously provides power to the tag via wireless signals. After the host device reads / writes atomizer data, it stops sending wireless signals to the electronic tag, thus severing the wireless communication connection. At this point, the electronic tag has no power supply. Therefore, the next time the host device provides power to the electronic tag via wireless signals, reading or writing atomizer data requires repeating the verification process using both the current access password and the preset access password.
[0102] As shown in Figure 6, after step S152, the method further includes step S16, which decrypts the atomizer data.
[0103] The atomizer data is encrypted and stored in the encrypted storage area of the electronic tag. It can only be read after the current access password is verified, and decryption is required after reading. This improves the security of the atomizer data and further enhances the anti-counterfeiting effect of the atomizer.
[0104] Step S153: Based on the atomizer data, change the atomizer from the locked state to the unlocked state, or keep it in the locked state.
[0105] For example, atomizer data includes information such as production date, manufacturer, brand, and flavor.
[0106] The process of switching the atomizer from a locked state to an unlocked state, or keeping it locked, based on atomizer data includes: determining whether the atomizer data is consistent with the preset data stored in the main unit; if yes, switching the atomizer from a locked state to an unlocked state; if no, keeping the atomizer locked.
[0107] In summary, another atomizer anti-counterfeiting method provided in this application includes: when the atomizer is inserted into the main body, reading the unique identification code; generating a current access password based on the unique identification code; sending verification request information to the electronic tag, the verification request information including the current access password; receiving verification result information returned by the electronic tag, determining whether the verification result information is a successful verification message, the verification result information including successful verification message and failed verification message, the successful verification message indicating that the current access password and the preset access password are consistent; if so, reading atomizer data; and changing the atomizer from a locked state to an unlocked state, or keeping it in a locked state, based on the atomizer data.
[0108] Therefore, this embodiment of the application reads the atomizer data by verifying that the current access password matches the preset access password, and then judges the legitimacy of the atomizer by the atomizer data, thereby further improving the anti-counterfeiting effect of the atomizer.
[0109] Please refer to Figure 7. The method further includes:
[0110] Step S181: Obtain the atomizer's suction parameters corresponding to the unique identification code.
[0111] Step S182: Determine whether the suction parameters meet the blacklist criteria.
[0112] Step S183: If yes, add the unique identifier to the blacklist.
[0113] For example, the vaping parameters include cumulative vaping time. The blacklist criterion is that the cumulative vaping time is greater than or equal to the atomizer's maximum vaping time. The main unit stores its unique identification code and records the cumulative vaping time of the atomizer corresponding to the unique identification code. It then determines whether the cumulative vaping time is greater than or equal to the atomizer's maximum vaping time. If so, the unique identification code is added to the blacklist. Therefore, the unique identification code has usage restrictions; meeting certain conditions will result in being blacklisted, preventing the unique identification code from being copied in bulk, thus improving the atomizer's anti-counterfeiting effect.
[0114] In some embodiments, the suction parameters may also include the number of suction ports, suction frequency, and the interval between suctions.
[0115] Please refer to Figure 8. After reading the unique identifier, the method further includes:
[0116] Step S191: Check if the unique identifier is in the blacklist.
[0117] Step S192: If yes, then keep the atomizer locked.
[0118] If not, proceed to the step of generating the current access password based on the unique identifier.
[0119] After reading the unique identification code, if the code is in the blacklist, the atomizer is immediately locked. If the code is not in the blacklist, the verification process of the current access password and the preset access password continues, thereby controlling the atomizer's operating state. It is evident that atomizers corresponding to unique identification codes in the blacklist are prohibited from generating aerosols, thus improving the atomizer's anti-counterfeiting effect.
[0120] Please refer to Figure 9, which shows an aerosol generating device provided in an embodiment of this application, which includes an atomizer 10 and a main body 20.
