[0042] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0043] Figure 1 An exemplary system architecture 100 is shown to which an embodiment of a method for identifying a tag or an apparatus for identifying a tag of the present application can be applied.

[0044] like Figure 1 As shown, the system architecture 100 may include electronic tags 101, 102, 103, a reader 104, a server 105, a network 106, and a network 107. The network 106 is used to provide a communication link medium between the electronic tags 101, 102, 103 and the reader 104. The network 107 is used to provide a communication link medium between the reader 104 and the server 105. The network 106 may include various wireless connection types, and the network 107 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0045] When the reader 104 receives the tag identification instruction, it sends a tag acquisition instruction to the electronic tags within its reading and writing range through the network 106. After receiving the tag acquisition instruction, the electronic tags 101, 102, and 103 send their tag sequences to the reader 104 through the network 106. The reader 104 generates a target tag fusion sequence using the tag sequences of the electronic tags 101, 102, and 103, and sends the target tag fusion sequence to the server 105 through the network 107.

[0046] The server 105 retrieves a tag set containing all tag sequences from the local storage, and for each preset number of tag sequences in the tag set, when the server 105 detects that the fusion sequence generated using the preset number of tag sequences is the same as the target tag fusion sequence, the preset number of tag sequences is determined as the target tag sequence.

[0047] It should be noted that the method for identifying a tag provided in the embodiments of the present disclosure is generally executed by the server 105 , and accordingly, the device for identifying a tag is generally disposed in the server 105 .

[0048] It should be understood that Figure 1 The numbers of electronic tags, readers, servers and networks in the embodiment are only for illustration purposes. Any number of electronic tags, readers, servers and networks may be provided as required.

[0049] Continue to refer Figure 2 , shows a process 200 of an embodiment of a method for identifying a tag according to the present disclosure, applied to a server, and comprising the following steps:

[0050] Step 201 : receiving a target tag fusion sequence, wherein the target tag fusion sequence is generated by using a preset number of target tag sequences and sequence operations.

[0051] In this embodiment, the execution subject of the method for identifying a tag (eg Figure 1 The server 105 shown in the figure can receive the target tag fusion sequence by wired or wireless means, wherein the target tag fusion sequence is a fusion sequence generated by a tag reader / tag reader / writer that reads the target tag, based on a preset number of target tag sequences obtained by the tag reader / tag reader / writer based on the preset number of electronic tags read by the tag reader / tag reader / writer after sequence operation. The sequence operation can be a sequence operation operation such as addition / subtraction of numerical sequences or logical operations on the target tag sequence by the tag reader.

[0052] Step 202: Obtain a tag sequence set including each tag sequence in a preset number of target tag sequences.

[0053] In this embodiment, the server may obtain a tag sequence set including all target tag sequences, which may be all tag sequences stored in the server or a subset of all tag sequence sets stored in the server including all target tag sequences.

[0054] Step 203 : for each preset number of tag sequences in the tag sequence set, in response to detecting that a fusion sequence generated by using the preset number of tag sequences and sequence operation is the same as a target tag fusion sequence, determining the preset number of tag sequences as target tag sequences.

[0055] In this embodiment, for each preset number of tag sequences in the tag sequence set, if the server detects that the fusion sequence generated by using the preset number of tag sequences and through sequence operation is the same as the target tag fusion sequence, the preset number of tag sequences in the tag sequence set are determined as the target tag sequence. The preset number may be the number of electronic tags currently recognized by the reader sent by the reader and received by the server, or the preset number may be the number of electronic tags recognized by the reader each time that is pre-constrained by the server and the reader.

[0056] In the method for identifying tags provided in this embodiment, a server receives a target tag fusion sequence generated by a preset number of target tag sequences and sequence operations, and obtains a tag sequence set including each tag sequence in the preset number of target tag sequences. For each preset number of tag sequences in the tag sequence set, when it is detected that a fusion sequence generated by the preset number of tag sequences and sequence operations is the same as the target tag fusion sequence, the preset number of tag sequences are determined to be the target tag sequences. Multiple tag sequences can be acquired and identified as a whole, reducing the communication between the server and the tag sequence acquisition device, saving communication resources and improving the efficiency of identifying tags.

[0057] Optionally, for each preset number of label sequences in the label sequence set, in response to detecting that a fusion sequence generated using the preset number of label sequences and sequence operations is the same as a target label fusion sequence, the preset number of label sequences are determined to be target label sequences, including: using all label sequences in the label sequence set and sequence operations to generate a global label fusion sequence; determining useless label sequences in the label sequence set that cannot be used to generate the target label fusion sequence based on the difference between the global label fusion sequence and the target label fusion sequence; in response to determining that the number of remaining label sequences after removing the useless label sequences in the label sequence set is a preset number, determining the remaining label sequences to be target label sequences.

[0058] In this embodiment, the server may perform sequence operations such as addition / subtraction of numerical sequences on all tag sequences in the tag sequence set, and determine the operation result as a global tag fusion sequence. The server may determine the tag sequence in the tag sequence set that produces the difference as a useless tag sequence based on the difference between the global tag fusion sequence and the target tag fusion sequence. For example, if the sequence operation is a sequence addition operation, and the number of bits of the global tag fusion sequence is more than the number of bits of the target tag fusion sequence, then the tag sequence in the tag sequence set that has more sequence bits than the number of bits of the target tag fusion sequence may be determined as a useless tag sequence that produces the sequence bit difference. It should be noted that the sequence operation for generating the global tag fusion sequence by the server is any sequence operation that is the same as the sequence operation for generating the target tag fusion sequence by the reader.

[0059] In this embodiment, when it is determined that the number of remaining label sequences in the label sequence set after removing useless label sequences is a preset number, the remaining label sequences may be determined as target label sequences.

[0060] Specifically, the server can determine the remaining label sequences through multiple rounds of iterations, that is, when the server determines the useless labels in the label sequence set based on the difference between the global label fusion sequence and the target label fusion sequence, the label sequence set without the useless label sequence is determined as the updated label sequence set, and it is judged whether the number of label sequences in the updated label sequence set is the same as the preset number; if different, an updated global label fusion sequence is generated based on all label sequences in the updated label sequence set, and the useless labels in the label sequence set are continuously determined and removed to update the label sequence set based on the difference between the updated global label fusion sequence and the target label fusion sequence, until the number of label sequences in the updated label sequence set is the same as the preset number, the iteration is stopped, and the label sequence in the updated label sequence set is determined as the target label sequence.

[0061] It can be understood that through multiple rounds of iterative processes, the server will filter out useless label sequences in the label sequence set one by one, and generate an updated global label fusion sequence based on the label sequences in the label sequence set after removing the useless labels. At this time, new differences will be generated between the updated global label fusion sequence and the target label fusion sequence, so that the server can filter out other useless label sequences according to the newly generated differences. Therefore, the server can filter out useless label sequences from the label sequence set in the process of successive screening to determine the target label sequence.

[0062] In this embodiment, a global label fusion sequence is generated based on all label sequences in the label sequence set stored in the server, and according to the difference between the global label fusion sequence and the target label fusion sequence, the label sequence in the label sequence set that creates the difference is determined as a useless label sequence, and the remaining label sequence in the label sequence set after removing the useless label sequence is determined as the target label sequence, which can improve the efficiency and convenience of determining the target label sequence.

[0063] Optionally, the method for identifying tags further includes: in response to determining that the number of remaining tag sequences after removing useless tag sequences in the tag sequence set is less than a preset number, determining that false tag sequences exist in the preset number of target tag sequences.

[0064] In this embodiment, when the number of remaining label sequences after removing all detected useless label sequences in the label sequence set is less than the number of target label sequences (ie, the preset number), it is determined that there are false label sequences in the target label sequence.

[0065] This embodiment determines whether there are false label sequences in the target label sequence based on the difference between the number of label sequences in the label sequence set after removing useless label sequences and the number of target label sequences, which can improve the efficiency and convenience of determining whether there are false label sequences in the target label sequence.

[0066] Further references Figure 3 , shows a process 300 of another embodiment of a method for identifying tags according to the present disclosure, the tag sequence is a binary tag sequence, and the method is applied to a server, comprising the following steps:

[0067] Step 301 : receiving a target tag fusion sequence, wherein the target tag fusion sequence is generated by using a preset number of target tag sequences and sequence operations.

[0068] Step 302: Obtain a tag sequence set including each tag sequence in a preset number of target tag sequences.

[0069] The description of step 301 and step 302 in this embodiment is consistent with the description of step 201 and step 202, and will not be repeated here.

[0070] Step 303, performing the following processing on the value of each bit sequence in the first preset sequence: in response to detecting that there is a label sequence in the label sequence set whose value on the bit sequence is the first value, determining that the value on the bit sequence in the first preset sequence is the first value; or, in response to detecting that there is no label sequence in the label sequence set whose value on the bit sequence is the first value, determining that the value on the bit sequence in the first preset sequence is the second value.

[0071] In this embodiment, a first preset sequence is first preset, and the first preset sequence can be a sequence in which the values ​​on each bit sequence are all empty, or a sequence in which the values ​​on each bit sequence are all random numbers. The following processing is performed for the numerical position (i.e., the storage unit of the bit sequence on the storage device) or the value of each bit sequence in the first preset sequence: if there is a label sequence in the label sequence set whose value on the bit sequence is the first value, the value on the bit sequence in the first preset sequence is set to the first value; or, if there is no label sequence in the label sequence set whose value on the bit sequence is the first value, the value on the bit sequence in the first preset sequence is set to the second value. It can be understood that the first value and the second value of the binary label sequence can be different letters, symbols, or numbers, etc.

[0072] For example, if the first preset sequence is "000000", and there are tag sequences "101100" and "000111" in the tag sequence set, where "1" is the first value and "0" is the second value, then the first preset sequence obtained after performing the above processing on the first preset sequence is "101111".

[0073] Step 304: determine the processed first preset sequence as the global label fusion sequence.

[0074] In this embodiment, the processed first preset sequence is determined as the global label fusion sequence.

[0075] Step 305 : Determine, according to the difference between the global tag fusion sequence and the target tag fusion sequence, useless tag sequences in the tag sequence set that cannot be used to generate the target tag fusion sequence.

[0076] In this embodiment, the server may determine, according to the difference between the global label fusion sequence and the target label fusion sequence, a label sequence in the label sequence set that produces the difference as a useless label sequence.

[0077] Step 306: In response to determining that the number of remaining tag sequences in the tag sequence set after removing useless tag sequences is a preset number, determining the remaining tag sequences as target tag sequences.

[0078] In this embodiment, when the server determines that the number of remaining label sequences after removing useless label sequences from the label sequence set is a preset number, the remaining label sequences may be determined as target label sequences.

[0079] The label sequence in this embodiment adopts a binary label sequence, and when there is a label sequence whose value of a certain position is a first value in the label sequence set, the value of the position in the global label fusion sequence is determined as the first value; when there is no label sequence whose value of a certain position is the first value in the label sequence set, the value of the position in the global label fusion sequence is determined as the second value, which can improve the efficiency of generating the global label fusion sequence.

[0080] Optionally, based on the difference between the global label fusion sequence and the target label fusion sequence, a useless label sequence in the label sequence set that cannot be used to generate the target label fusion sequence is determined, including: in response to detecting that the first bit sequence in the global label fusion sequence is a first numerical value, and the first bit sequence in the target label fusion sequence is a second numerical value, determining the label sequence whose first bit sequence in the label sequence set is the first numerical value as a useless label sequence; or, in response to detecting that the second bit sequence in the global label fusion sequence is a second numerical value, and the second bit sequence in the target label fusion sequence is the first numerical value, determining that there is a false label sequence in the target label sequence; wherein the first numerical value is used to characterize that the label sequence of the electronic label has response information at the corresponding bit sequence, and the second numerical value is used to characterize that the label sequence of the electronic label has no response information at the corresponding bit sequence.

[0081] In this embodiment, the first value can be used to represent that the label sequence of the electronic tag has response information in the corresponding bit sequence, and the second value can be used to represent that the label sequence of the electronic tag has no response information in the corresponding bit sequence. For example, each bit sequence in the label sequence can be each continuous or discontinuous time slice when the reader of the identification tag reads the electronic tag. In this case, the first value is used to represent that the label sequence of the electronic tag has replied to the reader with a response message within the corresponding time slice, and the second value is used to represent that the label sequence of the electronic tag has not replied to the reader with a response message within the corresponding time slice.

[0082] In this embodiment, when the server detects that the first sequence in the global label fusion sequence is the first value, and the first sequence in the target label fusion sequence is the second value, the label sequence whose first sequence is the first value is queried in the label sequence set, and the label sequence whose first sequence in the label sequence set is the first value is determined as a useless label sequence. It can be understood that the first sequence in the target label fusion sequence is the second value, which indicates that there is no label sequence in the target label with a response message at the first sequence; and the first sequence in the global label fusion sequence is the first value, which indicates that there is a label sequence in the label sequence set with a response message at the first sequence, then the label sequence in the label sequence set with a response message at the first sequence is a useless label sequence that needs to be screened out.

[0083] In this embodiment, when the server detects that the second bit sequence in the global label fusion sequence is the second value, and the second bit sequence in the target label fusion sequence is the first value, it is determined that there is a false label sequence in the target label sequence. It can be understood that the global label fusion sequence is a fusion sequence generated based on all label sequences in the label sequence set (that is, the target label sequence belongs to the label sequence set). If the value on the second bit sequence of the global label fusion sequence is the second value, it means that there is no label sequence in the label sequence set with a response message in the bit sequence; if the value on the second bit sequence in the target label fusion sequence is the first value, it means that there is a label sequence in the target label with a response message in the bit sequence. Since the label sequence set is a set of all label sequences stored by the server, the contradiction at this time is due to the existence of a false label in the target label sequence that does not belong to the label sequence set, and the false label is the label sequence with a response message in the second bit sequence.

[0084] It should be noted that the first sequence and the second sequence refer to any sequence in the global fusion label sequence or the target fusion label sequence.

[0085] In this embodiment, the first numerical value in the binary label sequence is used to represent the presence of response information in the corresponding position of the label sequence, and the second numerical value is used to represent the absence of response information in the corresponding position of the label sequence. Then, based on the difference in numerical values ​​at the same position between the global label fusion sequence and the target label fusion sequence, it is determined whether there are useless labels in the label sequence set or false labels in the target label sequence. This can improve the efficiency and convenience of determining useless labels, and improve the efficiency and convenience of determining whether there are false labels in the target labels.

[0086] In the above combination Figure 2 and Figure 3 In some optional implementations of the described embodiments, the method for identifying a tag further includes: searching a database for corresponding target information using the target tag sequence, and presenting the target information.

[0087] In this embodiment, the server can use the target tag sequence it identifies to query the target information corresponding to the target tag sequence in a database stored locally or in the cloud, and present the information on a display device that is communicatively connected to the server, or send the target information to the sending end of the target tag fusion sequence (for example, a reader that collects the target tag sequence) so that the sending end of the target fusion sequence presents the target information.

[0088] In this embodiment, the server uses the identified target tag sequence to query the corresponding target information in the database and presents the target information, so that the user can know the information corresponding to the target tag, which is convenient for the user to obtain the required information.

[0089] Further references Figure 4 , shows a process 400 of an embodiment of a method for generating a fusion tag according to the present disclosure, the method is applied to a reader, and includes the following steps:

[0090] Step 401: In response to receiving a tag identification instruction, a tag acquisition instruction is sent to the electronic tag.

[0091] In this embodiment, when the execution subject of the method for generating a fusion tag (for example Figure 1 After receiving the tag recognition instruction by wired or wireless means, the reader 104 shown in the figure can send a tag acquisition instruction to the electronic tag within its reading range. The tag recognition instruction can be an instruction for identifying the tag sent by the server, or an instruction for starting to identify the tag sent by the user to the reader through the touch display device / voice input device / physical or virtual case of the reader. The electronic tag can be a tag built based on radio frequency identification technology.

[0092] In this embodiment, the reader can divide the process of communicating with the electronic tag into multiple communication frames, and the frame length of each communication frame is fixed, that is, each communication frame contains a fixed number of time slices. After the reader sends a tag acquisition instruction (or a "frame start" instruction) to the electronic tag, each bit value in the electronic tag sequence replies to the reader with a response message within a separate time slice corresponding to the bit sequence.

[0093] Step 402: receiving multiple target label sequences returned based on the label acquisition instruction, and generating a target label fusion sequence using the multiple target label sequences and sequence operations.

[0094] In this embodiment, the reader can receive target tag sequences returned by multiple electronic tags based on tag acquisition instructions, and generate a target tag fusion sequence using the multiple target tag sequences and sequence operations. The reader can perform sequence operations such as numerical sequence addition / subtraction, sequence logic operations, etc. on the multiple target tag sequences, and determine the operation results as the target tag fusion sequence.

[0095] Step 403: Send the target tag fusion sequence to the server.

[0096] In this embodiment, the reader sends the target tag fusion sequence generated based on the acquired multiple target tag sequences to the server.

[0097] In this embodiment, the reader generates a single target tag fusion sequence based on the acquired target tag sequence of the electronic tag, and sends the target tag fusion sequence to the server so that the server can identify the target tag based on the target tag fusion sequence, which can reduce the communication frequency between the reader and the server, avoid waste of communication resources and improve communication efficiency.

[0098] Optionally, the target label sequence includes a binary label sequence, and a target label fusion sequence is generated using multiple target label sequences and sequence operations, including: performing the following processing on the value of each bit sequence in the second preset sequence: in response to detecting that there is a label sequence in which the value of the bit sequence is a first value among multiple target label sequences, determining that the value of the bit sequence in the second preset sequence is the first value; or, in response to detecting that there is a label sequence in which the value of the bit sequence is a second value among multiple target label sequences, determining that the value of the bit sequence in the second preset sequence is the second value; and determining the processed second preset sequence as the target label fusion sequence.

[0099] In this embodiment, firstly, a second preset sequence is preset, and the second preset sequence can be a sequence in which the values ​​on each bit sequence are all empty, or a sequence in which the values ​​on each bit sequence are all random numbers. The numerical position of each bit sequence in the second preset sequence (i.e., the storage unit of the bit sequence on the storage device) or the numerical value is processed as follows: if there is a target label sequence in the target label sequence whose numerical value on the bit sequence is the first numerical value, the numerical value on the bit sequence in the second preset sequence is determined as the first numerical value; or, if there is no label sequence in the target label sequence whose numerical value on the bit sequence is the first numerical value, the numerical value on the bit sequence in the second preset sequence is determined as the second numerical value. It can be understood that the first numerical value and the second numerical value of the binary label sequence can be different letters, symbols, or numbers, etc. Afterwards, the processed second preset sequence is determined as the target label fusion sequence. The binary label sequence used in this embodiment can simplify the steps of generating the target label fusion sequence.

[0100] Optionally, sending a tag acquisition instruction to the electronic tag includes: sending verification information to the electronic tag to instruct a verification reader; receiving a tag code returned by the electronic tag based on the verification information; querying feedback information based on the tag code, and sending the feedback information to the electronic tag; receiving multiple target tag sequences returned based on the tag acquisition instruction, including: receiving multiple target tag sequences returned based on the feedback information.

[0101] In this embodiment, after the reader receives the tag identification instruction, it sends verification information to multiple electronic tags within its reading range / identification range, and the verification information is used to instruct the electronic tag to verify the authenticity of the reader. Afterwards, the reader receives the tag codes returned by multiple electronic tags based on the verification information, queries the feedback information corresponding to the tag code in the local storage or cloud storage, and sends the feedback information to multiple electronic tags. If the feedback information is determined by the electronic tag to be verified, the reader receives multiple target tag sequences returned by the multiple electronic tags. In this embodiment, verifying the authenticity of the reader based on the feedback information can ensure the security of the tag information.

[0102] Further references Figure 5 , shows a process 500 of an embodiment of a method for sending a tag according to the present disclosure, the method is applied to an electronic tag, and includes the following steps:

[0103] Step 501: in response to receiving a tag acquisition instruction, sending a tag sequence to a reader, wherein a plurality of target tag sequences are used to generate a target tag fusion sequence.

[0104] In this embodiment, when the execution subject of the method for sending a tag (for example Figure 1 After receiving the tag acquisition instruction, the electronic tags 101, 102, and 103 shown in the figure send a target tag sequence to the reader. The target tag sequence can be an unencrypted plain text sequence or an encrypted sequence after a hash algorithm or a logical operation such as sequence XOR. The multiple target tag sequences sent to the reader by the multiple electronic tags that receive the tag acquisition instruction are used to generate a target tag fusion sequence. Specifically, after receiving the "frame start" message sent by the reader, the electronic tag can send a response message to the reader within the time slice divided by the reader in each frame, so that the length of each frame message is the same as the number of time slices in each frame.

[0105] The method for sending tags disclosed in this embodiment can enable the electronic tag that receives the tag acquisition instruction to send its own tag information to the reader, so that the reader generates a target tag fusion sequence based on multiple target tag sequences and sends it to the server, which can reduce the number of communications between the reader and the server to save communication resources.

[0106] Optionally, in response to receiving a tag acquisition instruction, sending a target tag sequence to the reader includes: in response to receiving verification information, sending a tag code to the reader; receiving feedback information returned by the reader based on the tag code; in response to determining that the feedback information meets the verification pass conditions, sending the target tag sequence to the reader.

[0107] In this embodiment, after the electronic tag receives the verification information sent by the reader, it sends its tag code to the reader. The tag code can be the tag sequence of the tag or the code representing the tag identity so that the reader cannot obtain the actual tag sequence of the electronic tag, thereby avoiding the leakage of the electronic tag sequence. Afterwards, the electronic tag receives the feedback information returned by the reader based on the tag code. If the electronic tag determines that the feedback information is legal information or the feedback information meets the verification pass condition, it sends its own target tag sequence to the reader.

[0108] This embodiment sends a tag code to a reader via an electronic tag, and determines whether the reader is an authenticated / verified reader based on whether the feedback information returned by the reader based on the tag code meets the verification pass conditions, and after determining that the reader is an authenticated / verified reader, sends the electronic tag's own target tag sequence to the reader, which can improve the security of communication.

[0109] In some application scenarios, after receiving the verification information sent to the reader, the electronic tag can send the tag code to the reader. After receiving the tag code, the reader queries the preset information (for example, a string of characters "AABBC") stored corresponding to the tag code in the local storage or cloud storage based on the tag code, and the reader sends the preset information corresponding to the tag code found as feedback information to the electronic tag. After receiving the preset information, the electronic tag determines whether the preset information meets the verification pass condition. If it is determined that the verification pass condition is met, the target tag sequence of the electronic tag is sent to the reader. For example, the electronic tag traverses whether there is information identical to the preset information in the storage unit of the electronic tag. If it is determined that it exists, it is determined that the preset information meets the verification pass condition.

[0110] In some application scenarios, after receiving the verification information sent by the reader, the electronic tag can generate a random number r1 and send the random sequence r1 and the tag code FID to the reader. After receiving the random number r1 and the tag code FID, the reader uses the tag code FID to query in the local storage or cloud storage. If the tag code FID is queried, the verification operation continues; if the tag code FID is not queried, the verification is stopped. After the reader queries the tag code FID, the reader first generates a random sequence r2 and calculates the A value and the B value according to formula (1) and formula (2).

[0111]

[0112]

[0113] Afterwards, r1 and the value of A||B are sent as feedback information to the electronic tag corresponding to the tag code FID. After receiving the value of A||B, the electronic tag generates B′ according to formula (3), formula (4), and formula (5).

[0114] D=PUF(P n ) (3)

[0115]

[0116]

[0117] Among them, P nThe signature represents the unique key in the nth round of authentication; P n+1 Represents the value of the unique key of the tag in the nth round of authentication (i.e., P n ) is the value of the key after being processed by the PUF (Physical Unclonable Functions) module. If the electronic tag determines whether B and B' are equal, it determines that the feedback information meets the verification pass condition / or the reader is an authenticated reader, and sends the target tag sequence of the electronic tag to the reader. If they are not equal, it determines that the reader is a false reader, and the electronic tag does not send the target tag sequence of the electronic tag to the reader.
