Description

NFC anti-counterfeiting label activation system

Technical Field

The invention relates to the technical field of data processing, in particular to an activation system of an NFC anti-counterfeiting label.

Background

The production activity of the near field communication (Near Field Communication, NFC) anti-counterfeiting label comprises a production data activation link, and the production data activation link is responsible for activating a batch of NFC anti-counterfeiting labels one by one. In activating the tags one by one, the correctness of all known production data (such as tag identification data, tag application data, tag key data, etc.) on the tags is verified, and then corresponding activation data (such as tag password and tag activation flag, etc.) is written to the tags. When the current label manufacturer activates the labels one by one in the production data activation link, a single card reader activation mode is adopted for processing conventionally. The single-card reader activation mode is that an NFC card reader is preset on a production transmission belt, a batch of single labels of NFC anti-counterfeiting labels are transmitted to the NFC card reader one by the transmission belt according to preset transmission speed and pause time, known production data verification and activation data writing operation are carried out on the current label by the NFC card reader in a single pause period, and the next label is transmitted to the NFC card reader to be stopped when the pause period is finished until the last label of the batch of NFC anti-counterfeiting labels is activated. It has been found through practice that this single reader activation approach does not result in a high number of tag activations that can be accomplished per unit time because only one NFC reader is operated in a single step.

The first card reader 11 is further used for performing tag identification data verification processing on the NFC tag 2 stopped under the card reader in linkage with the first server 16.

In a specific implementation manner of the embodiment of the present invention, the first card reader 11 is specifically configured to detect, during each single step pause process of the first belt 10, whether the NFC tag 2 is in a pause under the card reader to generate a corresponding first detection result when tag identification data verification is processed; if the first detection result is that the first detection result exists, adding 1 to the first sequence number; the method comprises the steps that a first tag identification reading instruction is sent to an NFC tag 2 which is stopped downwards by a card reader, and first identification data sent back by the NFC tag 2 is received; and transmits the first card reader data carrying the first serial number and the first identification data to the first server 16.

In a specific implementation manner of the embodiment of the present invention, the first card reader 11 is specifically configured to, when detecting whether there is a pause in the NFC tag 2 under the card reader, poll whether there is a new NFC tag 2 entering into the space below, and when finding that there is a new entering NFC tag 2, finish polling, establish connection with the current NFC tag 2, and set a corresponding first detection result as present. Here, the processing flow of polling the NFC reader and the NFC tag is a public standard flow, and specific reference may be made to standards such as ISO14443, ISO15693, ISO18092 or ISO21481, which are not further described herein. It should be noted that, the embodiment of the present invention further supports another sensor-based NFC tag detection mode, in which the first card reader 11 of the embodiment of the present invention further includes a first photosensitive sensor; the first photosensitive sensor is used for detecting whether an object is stopped below the first card reader 11, and sending a corresponding first signal to the first card reader 11 once the object is stopped; the first card reader 11 is configured to set the corresponding first detection result to be present when receiving the first signal sent by the first photosensitive sensor.

Here, it can be known from the foregoing that when the first card reader 11 and the first server 16 are linked to perform the tag identification data verification process on one NFC tag 2, the first tag sequence number field of the first tag record corresponding to the one NFC tag 2 in the first tag database is set to be the corresponding first sequence number, and the first sequence number and the second sequence number corresponding to the same NFC tag 2 are equal from the foregoing, so when the first server 16 receives the second card reader data sent by the second card reader 12, the corresponding current matching record, which is the corresponding first tag record corresponding to the one NFC tag 2, can be located by querying the first tag database based on the second sequence number and the first application data; if the current matching record is not empty, it indicates that the first tag record corresponding to the NFC tag 2 is successfully located and the application data is successfully compared, which means that the tag application data verification process is successful, so the first server 16 updates the second status bit of the first tag status field of the current matching record to the first status bit flag.

The third card reader 13 is further used for performing tag key data verification processing on the NFC tag 2 stopped below the card reader in linkage with the first server 16 and the first encryptor 17.

In another specific implementation manner of the embodiment of the present invention, the third card reader 13 is specifically configured to detect, during verification processing of tag key data, whether the NFC tag 2 is stopped under the card reader in each single step stopping process of the first belt 10, so as to generate a corresponding third detection result; if the third detection result is that the third detection result exists, adding 1 to the third sequence number; the method comprises the steps that a first tag key reading instruction is sent to an NFC tag 2 which is stopped downwards by a card reader, and first key data sent back by the NFC tag 2 are received; and calling a local random number module to generate a random number as a corresponding first random number; performing data encryption processing on the first random number by using first key data based on a preset encryption algorithm to generate corresponding first encrypted data; and transmits third card reader data carrying the third serial number, the first random number and the first encrypted data to the first server 16.

Here, the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the third card reader 13 is similar to the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the first card reader 11, and two detection manners are also supported: the detection mode of the NFC card reader for polling the NFC tag and the detection mode based on the photosensitive sensor are not repeatedly described herein; it should be noted that, when the third detection result is that there is a third detection result, it is indicated that the third card reader 13 has established a connection with the NFC tag 2 that is stopped under the card reader.

When receiving the first tag key reading instruction sent by the third card reader 13, the NFC tag 2 in the embodiment of the present invention extracts the locally stored tag key data as corresponding first key data and sends the first key data back to the third card reader 13. It should be noted that, in the embodiment of the present invention, the NFC tag 2 only responds to the first tag key reading instruction to return the locally stored tag key data to the card reader when the locally stored tag activation flag data (the data includes an activated state and an inactivated state, and is default to the inactivated state) is not in the activated state, and does not respond to the instruction if the locally stored tag activation flag data of the NFC tag 2 is in the activated state. Currently, since the activation of the NFC tag 2 has not been completed, the locally stored tag activation flag data is still in a default inactive state, so that the locally stored tag key data may be extracted as corresponding first key data back to the third reader 13. After obtaining the first key data, the third card reader 13 performs a random number generation process based on a random number module implemented by self-contained hardware or software to obtain a random number, i.e. a first random number; performing data encryption processing on the first random number by using first key data based on a preset encryption algorithm to generate corresponding first encrypted data, wherein the preset encryption algorithm defaults to a national encryption SM1 encryption algorithm; and then, the third card reader data carrying the third serial number, the first random number and the first encrypted data is sent to the first server 16, so that the first server 16 can verify the key data of the NFC tag 2 at the server side.

In another specific implementation manner of the embodiment of the present invention, the first server 16 is specifically configured to receive the third card reader data sent by the third card reader 13 during verification processing of the tag key data; extracting a third serial number, a first random number and first encrypted data from the third card reader data; inquiring a first tag database, and taking a first tag record matched with a first tag sequence number field and a third sequence number in the first tag database as a corresponding current matching record; when the current matching record is not empty, extracting a first tag identification data field of the current matching record as corresponding current identification data; the first data verification instruction carrying the current identification data, the first random number and the first encrypted data is sent to the first encryptor 17, and the first data verification state returned by the first encryptor 17 is received; and when the first data verification state is a successful state, updating a third state bit of the first tag state field of the current matching record to a first state bit mark.

In another specific implementation manner of the embodiment of the present invention, the first encryptor 17 is specifically configured to receive a first data verification instruction sent by the first server 16 during verification processing of tag key data; extracting current identification data, a first random number and first encrypted data from the first data verification instruction; inquiring a second tag database, and recording a second tag record matched with the current identification data in a second tag identification data field in the second tag database as a corresponding current record; when the current record is not empty, extracting a first tag key data field of the current record to serve as a corresponding current key; and based on a decryption algorithm matched with an encryption algorithm preset by the third card reader 13, performing data decryption processing on the first encrypted data by using the current key to generate corresponding first plaintext data; setting a corresponding first data verification state as a successful state when the first plaintext data is matched with the first random number; and returns the first data verification status to the first server 16.

Here, it can be known from the foregoing that when the first card reader 11 and the first server 16 are linked to perform the tag identification data verification process on one NFC tag 2, the first tag sequence number field of the first tag record corresponding to the one NFC tag 2 in the first tag database is set to the corresponding first sequence number, and the first sequence number and the third sequence number corresponding to the same NFC tag 2 are equal from the foregoing, so when the first server 16 receives the third card reader data sent by the third card reader 13, the corresponding current matching record, which is the corresponding first tag record corresponding to the one NFC tag 2, can be located by querying the first tag database based on the third sequence number; if the current matching record is not empty, the first label record corresponding to the NFC label 2 is successfully positioned; subsequently, the first server 16 obtains tag identification data of the NFC tag 2, i.e., current identification data, by reading the recorded first tag identification data field, and sends a first data verification instruction carrying the current identification data, the first random number, and the first encrypted data to the first encryptor 17 for performing user key validity verification. After receiving the first data verification instruction, the first encryptor 17 queries the second tag database based on the current identification data in the instruction to locate a second tag record corresponding to the NFC tag 2, namely a current record; the first tag key data field recorded at present is used as tag key data of the NFC tag 2, namely a current key; based on a decryption algorithm which is a national encryption SM1 decryption algorithm and is matched with an encryption algorithm which is a national encryption SM1 encryption algorithm preset by the third card reader 13, performing data decryption processing on the first encrypted data by using a current key to obtain corresponding first plaintext data; if the first plaintext data matches the first random number, it is indicated that the first key data obtained at the third card reader 13 side is identical to the current key stored at the first encryptor 17 side, and at this time, the first encryptor 17 returns a first data verification status set to a successful status to the first server 16. When the first server 16 receives the first data verification state set to the successful state, it confirms that the tag key data verification process of the NFC tag 2 is successful, so that the third status bit of the first tag status field of the current matching record is updated to the first status bit flag.

The fourth card reader 14 is further used for performing tag password data writing processing on the NFC tag 2 stopped below the card reader in linkage with the first server 16.

In another specific implementation manner of the embodiment of the present invention, the fourth card reader 14 is specifically configured to detect, during each single step pause process of the first belt 10, whether the NFC tag 2 is in a pause under the card reader during the tag password data writing process, so as to generate a corresponding fourth detection result; if the fourth detection result is that the fourth detection result exists, adding 1 to the fourth sequence number; transmitting the fourth card reader data carrying the fourth serial number to the first server 16, and receiving the first password data returned by the first server 16; the method comprises the steps that a first tag password writing instruction carrying first password data is sent to an NFC tag 2 which is stopped downwards by a card reader, and a first instruction state returned by the NFC tag 2 is received; when the first instruction state is a successful state, a first label password reading instruction is sent to the NFC label 2, and second password data returned by the NFC label 2 is received; and transmits fourth second card reader data carrying a fourth serial number and second password data to the first server 16.

Here, the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the fourth card reader 14 is similar to the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the first card reader 11, and two detection manners are also supported: the detection mode of the NFC card reader for polling the NFC tag and the detection mode based on the photosensitive sensor are not repeatedly described herein; it should be noted that, when the fourth detection result is presence, it indicates that the fourth card reader 14 has established a connection with the NFC tag 2 that is stopped under the card reader.

The fourth card reader 14 of the embodiment of the present invention sends the fourth card reader data carrying the fourth serial number to the first server 16 so as to obtain the tag password data of the NFC tag 2, i.e. the first password data, from the server; after receiving the first password data returned from the first server 16, the fourth card reader 14 writes the first password data to the NFC tag 2 through the first tag password writing instruction. When receiving a first tag password writing instruction sent by the fourth card reader 14, the NFC tag 2 in the embodiment of the present invention extracts first password data from the instruction and stores the first password data into a locally preset password data storage data block, and returns a first instruction state set as a successful state to the fourth card reader 14 when the data storage of the password data storage data block is successful. When receiving the first command status returned from the NFC tag 2 and set to the successful status, the fourth card reader 14 reads the stored tag password data, i.e. the second password data, from the NFC tag 2 by the first tag password reading command. When receiving a first tag password reading instruction sent by the fourth card reader 14, the NFC tag 2 in the embodiment of the present invention performs data reading processing on a locally preset password data storage data block and returns the read data as corresponding second password data to the fourth card reader 14. After receiving the second password data returned from NFC tag 2, fourth reader 14 sends the second password data to first server 16 together with the fourth serial number for background tag password verification.

In another specific implementation manner of the embodiment of the present invention, the first server 16 is specifically configured to identify, during the writing process of the tag password data, the current card reader data sent by the fourth card reader 14;

when the current card reader data is fourth card reader data, a fourth serial number is extracted from the fourth card reader data; inquiring a first tag database, and taking a first tag record matched with a first tag sequence number field and a fourth sequence number in the first tag database as a corresponding current matching record; if the current matching record is not empty, extracting a first tag password data field of the current matching record as corresponding first password data, and sending the first password data back to the fourth card reader 14;

when the current card reader data is fourth second card reader data, fourth serial number and second password data are extracted from the fourth second card reader data; inquiring a first tag database, and taking a first tag record in the first tag database, in which a first tag serial number field is matched with a fourth serial number and a first tag password data field is matched with second password data, as a corresponding current matching record; and when the current matching record is not empty, updating the fourth state bit of the first tag state field of the current matching record to be a first state bit mark.

Here, it can be known from the foregoing that when the first card reader 11 performs the tag identification data verification processing on one NFC tag 2 in linkage with the first server 16, the first tag sequence number field of the first tag record corresponding to the one NFC tag 2 in the first tag database is set to the corresponding first sequence number, and the first sequence number and the fourth sequence number corresponding to the same NFC tag 2 are equal from the foregoing, so when the first server 16 receives the fourth card reader data sent by the fourth card reader 14, the corresponding current matching record, which is the corresponding first tag record corresponding to the one NFC tag 2, can be located by querying the first tag database based on the fourth sequence number; if the current matching record is not empty, it indicates that the positioning of the first tag record corresponding to the NFC tag 2 is successful, and then the first server 16 extracts the first tag password data field of the current matching record as corresponding first password data to send back to the fourth card reader 14;

in addition, when receiving the fourth second card reader data sent by the fourth card reader 14, the first server 16 queries the first tag database through the fourth serial number and the second password data to obtain a corresponding current matching record, and if the current matching record is not empty, it indicates that there is a first tag record corresponding to the NFC tag 2 in the first tag database, and the tag password data in the record is consistent with the uploaded second password data, at this time, the first server 16 confirms that the writing process of the tag password data is successful, so that the fourth status bit of the first tag record corresponding to the NFC tag 2, that is, the first tag status field of the current matching record, is updated to the first status bit flag.

The fifth card reader 15 is further used for performing tag activation flag data writing processing on the NFC tag 2 stopped below the card reader in linkage with the first server 16.

In another specific implementation manner of the embodiment of the present invention, the fifth card reader 15 is specifically configured to detect, during each single step pause process of the first belt 10, whether the NFC tag 2 is in a pause under the card reader during the tag activation flag data writing process, to generate a corresponding fifth detection result; if the fifth detection result is that the fifth detection result exists, adding 1 to the fifth sequence number; transmitting fifth card reader data carrying a fifth serial number to the first server 16, and receiving a first authorization state returned by the first server 16; when the first authorization state is an authorization passing state, a first tag activation instruction is sent to the NFC tag 2 which is stopped down by the card reader, and a second instruction state returned by the NFC tag 2 is received; when the second instruction state is a successful state, a first activation state reading instruction is sent to the NFC tag 2, and first activation flag data sent back by the NFC tag 2 is received; and transmits fifth card reader data carrying a fifth serial number to the first server 16 when the first activation flag data matches a preset activation flag.

Here, the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the fifth card reader 15 is similar to the processing manner of detecting whether the NFC tag 2 has a pause under the card reader by the first card reader 11, and two detection manners are also supported: the detection mode of the NFC card reader for polling the NFC tag and the detection mode based on the photosensitive sensor are not repeatedly described herein; it should be noted that, when the fifth detection result is that there is a fifth detection result, it is indicated that the fifth card reader 15 has established a connection with the NFC tag 2 that is stopped under the card reader.

The fifth card reader 15 of the embodiment of the present invention sends fifth card reader data carrying a fifth serial number to the first server 16 so as to obtain activation authorization data, i.e. a first authorization state, of the NFC tag 2 from the server; after receiving the first authorization status returned from the first server 16, the fifth card reader 15 locally activates the NFC tag 2 through the first tag activation instruction if the first authorization status is an authorization passing status. When receiving the first tag activation instruction sent by the fifth card reader 15, the NFC tag 2 in the embodiment of the present invention changes the locally stored tag activation flag data from the default inactive state to the activated state, and returns a second instruction state set as a successful state to the fifth card reader 15 when the tag activation flag data is successfully modified. When receiving the second command status returned by the NFC tag 2 and set to the successful status, the fifth card reader 15 reads the stored tag activation flag data, i.e. the first activation flag data, from the NFC tag 2 according to the first activation status reading command. When receiving a first activation state reading instruction sent by the fifth card reader 15, the NFC tag 2 in the embodiment of the present invention sets activation flag data according to locally stored tag activation flag data, if the tag activation flag data is in an inactive state, sets the first activation flag data as a preset inactive flag, if the tag activation flag data is in an activated state, sets the first activation flag data as a preset activation flag, and sends the obtained first activation flag data back to the fifth card reader 15. After receiving the first activation flag data returned from the NFC tag 2, the fifth card reader 15 matches the first activation flag data with a preset activation flag, and if the matching of the first activation flag data with the preset activation flag indicates that the local activation process of the NFC tag 2 is successful, the fifth card reader data carrying the fifth serial number needs to be sent to the first server 16 to inform that the NFC tag at the front end of the background has completed the tag activation.

In another specific implementation manner of the embodiment of the present invention, the first server 16 is specifically configured to identify, during the writing process of the tag activation flag data, current card reader data sent by the fifth card reader 15;
