[0035] The following embodiments are only used to explain the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0036] The principle of the PUF anti-counterfeiting method for bottle commodity packaging:
[0037] PUF, or Physical Unclonable Function, is a hardware function implementation circuit that depends on chip characteristics. It generates unique input signals and output signals by extracting process parameter deviations that are inevitably introduced in the chip manufacturing process. The input signal is the excitation sent by the mobile phone through NFC, and the output signal is the only corresponding PUF sequence for this excitation. The PUF element in the present invention uses a PUF design based on a ring oscillator. The PUF output sequence is used as the unique anti-counterfeiting mark of the corresponding product in this package, and the corresponding product’s anti-counterfeiting information is mapped in the database, so that the PUF sequence is used as the product. The "chip fingerprint" of the PUF element in the anti-counterfeiting label also serves as the "commodity fingerprint" of the product corresponding to the anti-counterfeiting package. The bottle cap, bottle body and PUF element 1 are prior art,
[0038] A PUF-based anti-counterfeiting package for destructible bottles, including a bottle cap, a bottle body, a PUF element 1, a cap antenna 2, a cap neck joint antenna 3, and a neck antenna 4. The PUF element 1 is fixed on the bottle cap or On the bottle body, the lid antenna 2 is fixed on the bottle cap, the neck antenna 4 is fixed on the bottle neck of the bottle body, the upper end of the lid antenna 2 is electrically connected to the PUF element 1, and the lid neck is electrically connected to the upper end of the antenna 3. The lower end of the cover antenna 2 and the upper end of the neck antenna 4 are electrically connected to the lower end of the cover neck connection antenna 3. The cover neck connection antenna 3 makes the cover antenna 2 and the neck antenna 4 conduct, so that PUF can be completed by radio frequency signals The communication between the component and the card reader; the cover neck joint antenna 3 has three installation methods:
[0039] Method a: The antenna 3 of the neck of the cap is fixed on the bottle cap;
[0040] Method b: The antenna 3 is fixed on the bottle neck of the bottle;
[0041] Method c: The cap and neck joint antenna 3 is fixed at the joint between the bottle cap and the bottle neck;
[0042] When the bottle cap is opened for the first time, the connection between the neck of the lid and the antenna 3 and 4 is broken, or the connection between the neck of the lid and the antenna 3 and the antenna 2 is broken.
[0043] Further, the lid antenna 2 is spirally embedded on the inner side wall of the bottle cap, and the neck antenna 4 is spirally embedded on the outer side wall of the bottle neck of the bottle body.
[0044] Further, the PUF element 1, the cover antenna 2, the cover neck connection antenna 3, and the neck antenna 4 are covered by wrapping paper, which can be plastic sealing film; the cover antenna 2 and the neck antenna 4 are metal wires , The antenna 3 connected to the neck of the cover is a soft metal wire.
[0045] Further, the cover antenna 2 and the neck antenna 4 are copper wires, and the neck of the cover is connected to the aluminum wire of the antenna 3.
[0046] Further, the cover antenna 2 and the neck antenna 4 are metal wires marked by metal etching.
[0047] A PUF-based anti-counterfeiting method for destructible bottle anti-counterfeiting packaging, including double verification of activation signal and PUF sequence verification, to ensure the security of product information.
[0048] Further, it includes the following steps:
[0049] Step 1. The mobile terminal is close to the bottle cap of the product, and the specific excitation defined in the software package on the mobile terminal is sent to the cover antenna 2, the cover neck connection antenna 3 and the neck antenna 4 through the smart NFC module, the cover antenna 2. After receiving a specific excitation, the cover neck joint antenna 3 and the neck antenna 4 transmit to the PUF element and activate the PUF element;
[0050] Step 2. After the PUF element is activated, a PUF sequence is generated, and the PUF sequence is sent to the smart NFC module on the mobile terminal through the cover antenna 2, the cover neck connecting antenna 3 and the neck antenna 4, and the smart NFC module on the mobile terminal After receiving it, send it to the software package;
[0051] Step 3. After receiving the PUF sequence, the software package package transmits the PUF sequence to the server platform through the mobile network, and sends out an information request;
[0052] Step 4. After receiving the PUF sequence and the request application, the server platform verifies whether the PUF sequence is correct and whether the PUF sequence appears for the first time;
[0053] Step 5. If it is the correct and completely consistent PUF sequence and the PUF sequence appears for the first time, the server platform calls up the product information corresponding to the PUF sequence in the database, and sends it to the software package via the mobile network. The software package displays the product as Authentic and display product information;
[0054] Step 6. If any of the following situations occurs: incomplete PUF sequence, wrong PUF sequence, PUF sequence is not the first time, and the software package package cannot read the PUF sequence, then the server platform will not have product information feedback to the software package in the bag.
[0055] Further, the database is a storage database of merchant product information, which is provided by the merchant.
[0056] Further, the product information includes the production year, month and place of the product and the link to the merchant's official website, and the product information also includes the product appearance picture information or the product appearance video information.
[0057] Further, the PUF sequence is generated by PUF technology, the random number generated by PUF technology is a true random number, the PUF sequence is irregular and cannot be mathematically modeled, which ensures the clonality of the PUF sequence; the PUF sequence generated by PUF technology is 128 The random number sequence is composed of decimal numbers.
[0058] In the process of use: Because the PUF sequence uniquely identifies the product, and the input excitation of the PUF element corresponds to the output sequence one-to-one, only the correct excitation corresponding to this product can activate the PUF element to generate the PUF sequence. Only in the database Only the existing and correct sequence can find the relative product information in the database, which can be called by the server to be displayed in the mobile phone application software.
[0059] In step 1, the present invention uses the smart phone NFC module to support a software package that is mobile phone application software, which defines specific incentives for the corresponding PUF components, and this software package can be connected to the merchant’s corresponding WeChat applet or mobile phone application software , Which can change the card reader device from a professional card reader to a user’s mobile phone. As long as the user turns on the mobile phone NFC module, opens the corresponding WeChat applet or the corresponding mobile phone application software, and enters the relevant anti-counterfeiting interface, the user can send incentives to the PUF component through the mobile phone NFC module by placing the mobile phone close to the corresponding anti-counterfeiting area of the bottle cap of the commodity, and receiving The PUF sequence output by the PUF element and transmitted through the antenna, and then by sending the anti-counterfeiting query request and the PUF sequence to the server, the corresponding product information and authenticity judgment called, distributed, and transmitted by the server will be received.
[0060] In step 2, each specific incentive of the aforementioned PUF element corresponds to a unique PUF serial number. Only the correct incentive can activate the PUF element and generate the corresponding serial number. This specific incentive is only generated by the official mobile phone application software or WeChat applet of the corresponding merchant This specific incentive can only activate the corresponding PUF element, the forged specific incentive cannot activate the commodity PUF element, and the forged commodity anti-counterfeiting mark cannot be used to stimulate the generation of the corresponding PUF sequence, which results in the first protection of authenticity verification.
[0061] In step 4, only the correct PUF sequence can match the corresponding product information in the database, which is called by the server platform and sent to the mobile client, and the server platform will determine whether the PUF sequence appears for the first time. If it does not appear for the first time, consumers will be warned through the mobile client, which will result in a second layer of protection for authenticity verification.
[0062] In step 5, the merchant can convert the product information corresponding to the PUF sequence into text information, such as product production year, month and place, and link to the merchant’s official website; image information, such as product series pictures; product video information, such as product or new product promotion Video and other methods are displayed on the user's mobile phone client.
[0063] The commodity information support is provided by the database provided by the merchant, which ensures the non-disclosure of the commodity information.
[0064] Merchants can update the corresponding product database by themselves. Therefore, if the merchant wants to recycle the product packaging or PUF components for reuse, the corresponding serial number in the database can be updated to zero; if the merchant wants to update the product information, it can also Update the corresponding product information in the database.
[0065] Further, when criminals have not mastered the corresponding winding technology, recovery, repair or reproduction of the corresponding PUF anti-counterfeiting marks will incur great costs and difficulties. In addition, even if the repair is completed, the unupdated database will remind consumers that the product security code has appeared.
[0066] The PUF sequence is invisible to users from beginning to end, and the PUF sequence cannot be seen directly in the software package. It is extremely difficult for criminals to embezzle, ensuring the security of the PUF sequence and the product anti-counterfeiting authentication mark.
[0067] The anti-counterfeiting label PUF element of the present invention receives excitation through its surrounding antenna, and sends a radio frequency signal to output a PUF sequence. Once the bottle cap is opened, the cap-neck connection antenna is broken and divided into two parts, the cap antenna and the neck antenna, of which only the cap antenna is connected to the PUF element to receive and transmit radio frequency signals for the PUF element.
[0068] The antenna is divided into two parts: the cover part and the neck part. The middle part is connected by metal. The metal connection can be broken with the opening of the bottle cap, and it is difficult to recover after the break, so that the antenna connected to the PUF element is shortened to the bottle cap part, and it is difficult to receive the card reader device. The stimulus to block the communication between the PUF element and the card reader.
[0069] UF technology uses the inevitable process errors in the chip production process. The random numbers generated are true random numbers, irregular and unable to be mathematically modeled, ensuring the uniqueness of the sequence; the random sequence generated by PUF technology is 128-bit decimal The number structure avoids the exhaustion of the serial number and ensures the non-repeatability of the sequence.
[0070] The PUF sequence only exists in the form of electrical signals, and the user is always invisible, and the server platform described is constructed by the system of this method. The NFC module is called by the official application software of the relevant product, and the stimulus that the NFC needs to be emitted will be defined in the application software package that we configure for it. The PUF component is a passive electronic tag. There is no power supply inside it, and it is driven by the electromagnetic wave received (that is, the specific excitation sent by the mobile phone). The PUF technology only improves the inherent physical structure of the chip, and uses the inhomogeneity of the chip manufacturing process to generate the unique identification PUF sequence of the chip.
[0071] Specifically, the PUF sequence is composed of 128 decimal numbers, which are invisible to the user from beginning to end, so there is no need to worry about sequence embezzlement. The user visual interface only has relevant product information on the mobile phone application software or WeChat applet.
[0072] This embodiment provides an anti-counterfeiting method for bottle commodities. The commodities are wines and the packaging bottles are wine bottles, which are composed of a bottle cap and a bottle body. Among them, the top of the bottle cap is embedded with a PUF element, the wall of the bottle cap is wrapped with copper wire, and the bottleneck is also embedded with a spiral copper wire. The cap and the neck are connected by aluminum wires at the junction of the cap and the neck.
[0073] When the user buys this wine, such as Figure 4 , Open the authenticity query interface in the official wine app, follow the prompts to open the NFC connection method that comes with the phone, and then move the phone close to the bottle cap.
[0074] The antenna on the bottle cap receives the electromagnetic wave excitation from the mobile phone's NFC and transmits it to the PUF element. After the passive electronic tag PUF component is activated by this excitation, the corresponding 128-bit PUF sequence is generated, which is sent to the mobile phone as an electrical signal through the antenna. After the mobile phone APP receives it through NFC, it sends the PUF sequence to the server through the 4G mobile network, and the server calls the database to check whether the PUF sequence is correct or not; if it is correct, it further determines whether the sequence is queried for the first time; if it is, call the relevant The product information is sent to the user’s mobile phone. The APP in the mobile phone will display the corresponding product information and prompt that the wine is genuine. See Figure 5.
[0075] Furthermore, if the PUF sequence is not queried for the first time, the anti-counterfeiting mark of this product on the mobile phone has been checked several times in which year, month, day, and hour, and it indicates that the wine may be a counterfeit, and the official purchase channel is also provided. Link to complaints.
[0076] Furthermore, if the PUF sequence is wrong, the mobile phone displays that the anti-counterfeiting is wrong, and the software package indicates that the wine is a counterfeit, and at the same time, the official purchase channel and the connection related to the complaint are provided.
[0077] Furthermore, if the stimulus sent to the PUF sequence is wrong, the PUF element cannot be activated, so the mobile phone cannot get the relevant response. At this time, the mobile phone waits for 10 seconds. When the time is up, the mobile phone displays the waiting timeout and prompts to check the network status. The Internet is correct. This wine is a fake, and it also provides official purchase channels and links to complaints.
[0078] Furthermore, if the wine is a genuine packaging recycled by criminals and is shoddy and circulated in the market, the lid antenna and the neck antenna will break at the junction of the lid and the neck. At this time, the PUF component cannot receive the incentives sent by the mobile phone. The mobile phone will wait for 10 seconds. When the time is up, the mobile phone displays the waiting timeout and prompts to check the network status. If there is no problem with the network, the software package prompts that the wine is a fake, and the official website is provided. The purchase channel is connected with the complaint.
[0079] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principles of the present invention, several improvements and modifications can be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
