Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows an exemplary system architecture 100 to which embodiments of the method for identifying a tag or the apparatus for identifying a tag of the present application may be applied.

As shown in fig. 1, the system architecture 100 may include

electronic tags

101, 102, 103, a reader 104, a server 105, a network 106, and a network 107. Network 106 is used to provide a communication link medium between

electronic tags

101, 102, 103 and reader 104. Network 107 is used to provide a communication link medium between reader 104 and server 105. Network 106 may include various wireless connection types and network 107 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.

When the reader 104 receives the tag identification instruction, the tag acquisition instruction is sent to the electronic tags in the read-write range of the reader through the network 106, and after the

electronic tags

101, 102 and 103 receive the tag acquisition instruction, the tag sequence is sent to the reader 104 through the network 106. The reader 104 generates a target tag fusion sequence by using the tag sequences of the

electronic tags

101, 102, 103, and transmits the target tag fusion sequence to the server 105 through the network 107.

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

It should be noted that the method for identifying a tag provided by the embodiment of the present disclosure is generally performed by the server 105, and accordingly, the apparatus for identifying a tag is generally disposed in the server 105.

It should be understood that the number of tags, readers, servers and networks in fig. 1 is merely illustrative. There may be any number of tags, readers, servers and networks, as desired for implementation.

With continued reference to fig. 2, a flow 200 of one embodiment of a method for identifying tags is shown, applied to a server, comprising the steps of:

step 201, receiving a target tag fusion sequence, wherein the target tag fusion sequence is generated by adopting a preset number of target tag sequences and sequence operation.

In this embodiment, an executing entity (for example, the server 105 shown in fig. 1) of the method for identifying tags may receive a target tag fusion sequence in a wired or wireless manner, where the target tag fusion sequence is a fusion sequence generated by performing sequence operations on a preset number of target tag sequences obtained based on a preset number of electronic tags read by a tag reader/tag reader that reads a target tag. The sequence operation may be a sequence operation such as addition/subtraction or logic operation of a numerical sequence performed on a target tag sequence by the tag reader.

Step 202, a tag sequence set including each of a preset number of target tag sequences is obtained.

In this embodiment, the server may obtain a tag sequence set including all of the target tag sequences. The set of tag sequences may be all of the tag sequences stored by the server, or may be a subset of the set of all of the tag sequences stored by the server that includes all of the target tag sequences.

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

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 through sequence operation is the same as the target tag fusion sequence, the preset number of tag sequences in the tag sequence set is determined as the target tag sequence. The preset number may be the number of the electronic tags currently identified by the reader, which is sent by the reader and received by the server, and the preset number may also be the number of the electronic tags identified by the reader each time, which is pre-constrained by the server and the reader.

In the method for identifying a tag provided by this embodiment, a server receives a target tag fusion sequence generated by a preset number of target tag sequences and sequence operation, acquires a tag sequence set including each of the preset number of target tag sequences, and determines, for each preset number of tag sequences in the tag sequence set, that a fusion sequence generated by the preset number of tag sequences and sequence operation is the same as the target tag fusion sequence, the preset number of tag sequences is a target tag sequence, so that a plurality of tag sequences can be integrally acquired and identified, communication between the server and a tag sequence acquisition device is reduced, communication resources are saved, and tag identification efficiency is improved.

Optionally, 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 that the preset number of tag sequences is the target tag sequence, includes: generating a global label fusion sequence by adopting all label sequences in the label sequence set and sequence operation; determining a useless tag sequence which cannot be used for generating a target tag fusion sequence in the tag sequence set according to the difference between the global tag fusion sequence and the target tag fusion sequence; and determining the residual label sequences as target label sequences in response to determining that the number of the residual label sequences is a preset number after useless label sequences are removed from the label sequence set.

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, according to a difference between the global tag fusion sequence and the target tag fusion sequence, a tag sequence in the tag sequence set that generates the difference as a useless tag sequence. For example, if the sequence operation is an addition operation of sequences and the number of bits of the global tag fusion sequence is greater than the number of bits of the target tag fusion sequence, a tag sequence having a greater number of bits than the number of bits of the target tag fusion sequence in the tag sequence set may be determined as an unnecessary tag sequence that causes a difference in the number of bits of the sequence. The sequence operation for the server to generate the global tag fusion sequence is an arbitrary sequence operation similar to the sequence operation for the reader to generate the target tag fusion sequence.

In this embodiment, when it is determined that the number of remaining tag sequences from which useless tag sequences are removed in the tag sequence set is a preset number, the remaining tag sequences may be determined as target tag sequences.

Specifically, the server may determine the remaining tag sequences through a plurality of iterations, that is, after determining the useless tags in the tag sequence set according to the difference between the global tag fusion sequence and the target tag fusion sequence, the server determines the tag sequence set from which the useless tag sequences are removed as an updated tag sequence set, and determines whether the number of tag sequences in the updated tag sequence set is the same as a preset number; and if the label sequences are different, generating an updated global label fusion sequence based on all the label sequences in the updated label sequence set, continuously determining and removing useless labels in the label sequence set according to the difference between the updated global label fusion sequence and the target label fusion sequence to update the label sequence set, stopping iteration until the number of the label sequences in the updated label sequence set is the same as the preset number, and determining the label sequences in the updated label sequence set as the target label sequences.

It can be understood that through multiple rounds of iteration processes, the server screens useless tag sequences in the tag sequence set successively, and generates an updated global tag fusion sequence based on the tag sequences in the tag sequence set from which the useless tags are removed, at this time, a new difference is generated between the updated global tag fusion sequence and the target tag fusion sequence, so that the server screens other useless tag sequences according to the newly generated difference, and therefore, the server can screen the useless tag sequences from the tag sequence set in the successive screening process to determine the target tag sequences.

In this embodiment, a global tag fusion sequence is generated based on all tag sequences in a tag sequence set stored by a server, a tag sequence for making the difference in the tag sequence set is determined as an unnecessary tag sequence according to the difference between the global tag fusion sequence and a target tag fusion sequence, and a remaining tag sequence from which the unnecessary tag sequence is removed in the tag sequence set is determined as a target tag sequence, so that the efficiency and convenience in determining the target tag sequence can be improved.

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

In this embodiment, when the number of remaining tag sequences is smaller than the number of target tag sequences (i.e., a preset number) after all detected useless tag sequences in the tag sequence set are removed, it is determined that a fake tag sequence exists in the target tag sequences.

According to the embodiment, whether the target label sequence has the false label sequence or not is determined according to the difference between the number of the label sequences in the label sequence set without the useless label sequence and the number of the target label sequences, so that the efficiency and convenience for determining whether the target label sequence has the false label sequence or not can be improved.

With further reference to fig. 3, a flow 300 of another embodiment of a method for identifying tags according to the present disclosure is shown, the tag sequence being a binary tag sequence, the method applied to a server, comprising the steps of:

step 301, receiving a target tag fusion sequence, wherein the target tag fusion sequence is generated by adopting a preset number of target tag sequences and sequence operation.

Step 302, a tag sequence set including each of a preset number of target tag sequences is obtained.

In this embodiment, the descriptions of step 301 and step 302 are the same as the descriptions of step 201 and step 202, and are not repeated here.

Step 303, performing the following processing on the value of each bit sequence in the first preset sequence: in response to detecting that a tag sequence with a first value on the bit sequence exists in the tag sequence set, determining that the value on the bit sequence in a first preset sequence is the first value; or, in response to detecting that there is no tag sequence with the first value in the set of tag sequences, determining that the value in the bit sequence in the first predetermined sequence is the second value.

In this embodiment, a first preset sequence is preset first, where the first preset sequence may be a sequence in which the numerical values in each bit sequence are all null, or may be a sequence in which the numerical values in each bit sequence are all random numbers, and the following processing is performed for the numerical value position (i.e., the storage unit of the bit sequence on the storage device) or the numerical value of each bit sequence in the first preset sequence: if a tag sequence with the value of the bit sequence being a first value exists in the tag sequence set, setting the value of the bit sequence in a first preset sequence as the first value; or, if there is no tag sequence with the value of the first value in the set of tag sequences, the value of the first predetermined sequence in the bit sequence is set as the second value. It is understood that the first numerical value, the second numerical value of the binary tag sequence may be different letters, symbols, numbers, or the like.

For example, if the first predetermined sequence is "000000", and tag sequences "101100" and "000111" exist in the tag sequence set, where "1" is a first numerical value and "0" is a second numerical value, the first predetermined sequence obtained by performing the above processing on the first predetermined sequence is "101111".

And step 304, determining the processed first preset sequence as a global label fusion sequence.

In this embodiment, the processed first preset sequence is determined as a global tag fusion sequence.

And 305, determining a useless tag sequence which cannot be used for generating the target tag fusion sequence in the tag sequence set according to the difference between the global tag fusion sequence and the target tag fusion sequence.

In this embodiment, the server may determine, according to a difference between the global tag fusion sequence and the target tag fusion sequence, a tag sequence in the tag sequence set that generates the difference as a useless tag sequence.

Step 306, in response to determining that the number of the remaining tag sequences without the useless tag sequences in the tag sequence set is a preset number, determining that the remaining tag sequences are target tag sequences.

In this embodiment, when the server determines that the number of remaining tag sequences from which useless tag sequences are removed in the tag sequence set is a preset number, the remaining tag sequences may be determined as target tag sequences.

The tag sequence in this embodiment is a binary tag sequence, and when a tag sequence whose numerical value of a certain order is a first numerical value exists in the tag sequence set, the numerical value on the certain order of the global tag fusion sequence is determined as the first numerical value, and when a tag sequence whose numerical value of a certain order is the first numerical value does not exist in the tag sequence set, the numerical value on the certain order of the global tag fusion sequence is determined as a second numerical value, so that efficiency of generating the global tag fusion sequence can be improved.

Optionally, determining a useless tag sequence in the tag sequence set that cannot be used for generating the target tag fusion sequence according to a difference between the global tag fusion sequence and the target tag fusion sequence, including: in response to detecting that the first bit sequence in the global tag fusion sequence is a first numerical value and the first bit sequence in the target tag fusion sequence is a second numerical value, determining the tag sequence with the first bit sequence being the first numerical value in the tag sequence set as a useless tag sequence; or, in response to detecting that the second bit sequence in the global tag fusion sequence is the second numerical value and the second bit sequence in the target tag fusion sequence is the first numerical value, determining that a false tag sequence exists in the target tag sequence; the first numerical value is used for representing that the tag sequence of the electronic tag has response information on the corresponding bit sequence, and the second numerical value is used for representing that the tag sequence of the electronic tag has no response information on the corresponding bit sequence.

In this embodiment, the first value may be used to represent that the tag sequence of the electronic tag has response information in the corresponding bit sequence, and the second value may be used to represent that the tag sequence of the electronic tag has no response information in the corresponding bit sequence. For example, each bit sequence in the tag sequence may be each continuous or discontinuous time slice during which the reader for identifying the tag reads the electronic tag, in this case, the first value is used to characterize that the tag sequence of the electronic tag replies to the reader with a response message in the corresponding time slice, and the second value is used to characterize that the tag sequence of the electronic tag does not reply to the reader with a response message in the corresponding time slice.

In this embodiment, when the server detects that the first bit sequence in the global tag fused sequence is the first numerical value and the first bit sequence in the target tag fused sequence is the second numerical value, the server queries the tag sequence of which the first bit sequence is the first numerical value in the tag sequence set, and determines the tag sequence of which the first bit sequence is the first numerical value in the tag sequence set as the useless tag sequence. It can be understood that the first bit sequence in the target tag fusion sequence is the second numerical value which characterizes the tag sequence in the target tag without the response message existing on the first bit sequence; and the first bit sequence in the global label fusion sequence is a first value, which represents that the label sequence with the response message on the first bit sequence exists in the label sequence set, so that the label sequence with the response message on the first bit sequence in the label sequence set is a useless label sequence which needs to be screened out.

In this embodiment, when the server detects that the second bit sequence in the global tag fused sequence is the second value and the second bit sequence in the target tag fused sequence is the first value, it is determined that a false tag sequence exists in the target tag sequence. It can be understood that the global tag fusion sequence is a fusion sequence generated based on all tag sequences in the tag sequence set (that is, the target tag sequence belongs to the tag sequence set), and if the value on the second bit sequence of the global tag fusion sequence is the second value, it represents that there is no tag sequence of the response message on the bit sequence in the tag sequence set; if the value of the second bit sequence in the target label fusion sequence is the first value, the target label is represented to have a label sequence with a response message on the bit sequence, and the label sequence set is a set of all label sequences stored by the server, so that the contradiction is caused by the fact that a false label which does not belong to the label sequence set exists in the target label sequence, and the false label is the label sequence with the response message on the second bit sequence.

The first bit sequence and the second bit sequence refer to any bit sequence in the global fusion tag sequence or the target fusion tag sequence.

In this embodiment, a first numerical value in a binary tag sequence is used to represent that a tag sequence has response information on a corresponding bit sequence, and a second numerical value represents that a tag sequence has no response information on the corresponding bit sequence, and then based on a difference between values on the same bit sequence between a global tag fusion sequence and a target tag fusion sequence, whether a useless tag in a tag sequence set or a false tag exists in the target tag sequence is determined, so that efficiency and convenience for determining the useless tag can be improved, and efficiency and convenience for determining whether the false tag exists in the target tag can be improved.

In some optional implementations of the embodiments described above in connection with fig. 2 and 3, the method for identifying a tag further comprises: and searching corresponding target information in the database by using the target label sequence, and presenting the target information.

In this embodiment, the server may query, in a database stored locally or in a cloud, target information corresponding to the target tag sequence by using the target tag sequence identified by the server, and present the information on a display device in communication connection with the server, or send the target information to a 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.

In this embodiment, the server queries corresponding target information in the database by using the identified target tag sequence and presents the target information, so that the user can know the information corresponding to the target tag, and the user can conveniently obtain required information.

With further reference to fig. 4, a flow 400 of one embodiment of a method for generating a fused tag according to the present disclosure is shown, applied to a reader, comprising the steps of:

step 401, in response to receiving the tag identification instruction, sending a tag obtaining instruction to the electronic tag.

In this embodiment, after an execution subject (e.g., the reader 104 shown in fig. 1) of the method for generating the fusion tag receives the tag identification instruction in a wired or wireless manner, a tag acquisition instruction may be sent to the electronic tags within the reading range of the execution subject. The tag identification command may be a command for identifying a tag transmitted from the server, or a command for starting to identify a tag transmitted from the user to the reader through a touch display device, a voice input device, or a physical or virtual case of the reader. The electronic tag may be a tag built based on radio frequency identification technology.

In this embodiment, the reader may divide the process of communicating with the electronic tag into a plurality of communication frames, and the frame length of each communication frame is fixed, that is, each communication frame includes 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 a response message to the reader within a separate time slice corresponding to the bit sequence.

Step 402, receiving a plurality of target tag sequences returned based on the tag obtaining instruction, and generating a target tag fusion sequence by adopting the plurality of target tag sequences and sequence operation.

In this embodiment, the reader may receive a target tag sequence returned by a plurality of electronic tags based on the tag obtaining instruction, and generate a target tag fusion sequence by using the plurality of target tag sequences and sequence operation. The reader can perform sequence operations such as addition/subtraction of numerical value sequences, sequence logic operation and the like on a plurality of target label sequences, and determine the operation result as a target label fusion sequence.

And step 403, sending the target label fusion sequence to a server.

In this embodiment, the reader sends a target tag fusion sequence generated based on the acquired plurality of target tag sequences to the server.

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

Optionally, the target tag sequence includes a binary tag sequence, and generating a target tag fusion sequence by using a plurality of target tag sequences and sequence operations, including: the following processing is performed for the value of each bit sequence in the second preset sequence: in response to detecting that a tag sequence with a value on the bit sequence being a first value exists in a plurality of target tag sequences, determining that the value on the bit sequence in a second preset sequence is the first value; or, in response to detecting that a tag sequence with a second value in the bit sequence exists in the plurality of target tag sequences, determining that the value in the bit sequence in the second preset sequence is the second value; and determining the second preset sequence after the processing as a target label fusion sequence.

In this embodiment, a second preset sequence is preset first, where the second preset sequence may be a sequence in which the numerical values in each bit sequence are all null, or may be a sequence in which the numerical values in each bit sequence are all random numbers, and the following processing is performed for the numerical value position (i.e., the storage unit of the bit sequence on the storage device) or the numerical value of each bit sequence in the second preset sequence: if the target label sequence with the numerical value of the bit sequence as the first numerical value exists in the target label sequence, the numerical value of the bit sequence in the second preset sequence is determined as the first numerical value; or, if there is no tag sequence with the value of the bit sequence being the first value in the target tag sequence, the value of the bit sequence in the second predetermined sequence is determined as the second value. It is understood that the first value, the second value, etc. of the binary tag sequence may be different letters, symbols, or numbers. And then, determining the second preset sequence after the processing as a target label fusion sequence. The step of generating the target tag fusion sequence can be simplified by adopting the binary tag sequence.

Optionally, sending a tag obtaining instruction to the electronic tag includes: sending verification information indicating a verification reader to the electronic tag; receiving a label code returned by the electronic label based on the verification information; inquiring feedback information based on the tag codes, and sending the feedback information to the electronic tag; receiving a plurality of target tag sequences returned based on a tag fetch instruction, including: and receiving a plurality of target label sequences returned based on the feedback information.

In this embodiment, after receiving the tag identification instruction, the reader sends verification information to the plurality of electronic tags in the reading range/identification range of the reader, where the verification information is used to instruct the electronic tags to verify the authenticity of the reader. And then, the reader receives the tag codes returned by the plurality of electronic tags based on the verification information, inquires feedback information corresponding to the tag codes in local storage or cloud storage, and sends the feedback information to the plurality of electronic tags. And if the feedback information is determined to pass the verification by the electronic tags, the reader receives a plurality of target tag sequences returned by the electronic tags. In this embodiment, the authenticity of the reader is verified based on the feedback information, so that the security of the tag information can be ensured.

With further reference to fig. 5, a flow 500 of one embodiment of a method for transmitting a tag according to the present disclosure is shown, the method applied to an electronic tag, comprising the steps of:

step 501, in response to receiving a tag obtaining instruction, sending a tag sequence to a reader, where a plurality of target tag sequences are used to generate a target tag fusion sequence.

In this embodiment, when an execution subject (for example, the

electronic tags

101, 102, and 103 shown in fig. 1) of the method for sending a tag receives a tag obtaining instruction, a target tag sequence is sent to a reader, where the target tag sequence may be an unencrypted plain code sequence or an encrypted sequence that is subjected to a hash algorithm or a logical operation such as an xor. And the target tag sequences sent to the reader by the electronic tags receiving the tag acquisition instruction are used for generating a target tag fusion sequence. Specifically, after receiving a "frame start" message sent by the reader, the electronic tag may send a response message to the reader within a 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.

The method for sending the tags can enable the electronic tags receiving the tag acquisition instructions to send tag information of the electronic tags to the reader, enable the reader to generate the target tag fusion sequence based on the target tag sequences and send the target tag fusion sequence to the server, and can reduce the communication times between the reader and the server so as to save communication resources.

Optionally, sending the target tag sequence to the reader in response to receiving the tag obtaining instruction, includes: in response to receiving the verification information, sending a tag code to the reader; receiving feedback information returned by the reader based on the tag codes; and responding to the fact that the feedback information is determined to be in accordance with the verification passing condition, and sending the target label sequence to the reader.

In this embodiment, after receiving the verification information sent by the reader, the electronic tag sends its tag code to the reader, where the tag code may be a tag sequence of the tag or a code representing the identity of the tag, so that the reader cannot obtain an actual tag sequence of the electronic tag, thereby avoiding leakage of the electronic tag sequence. And then, the electronic tag receives feedback information returned by the reader based on the tag code. And if the electronic tag determines that the feedback information is legal information or the feedback information meets the verification passing condition, sending a target tag sequence of the electronic tag to the reader.

In the embodiment, the tag code is sent to the reader through the electronic tag, whether the reader is an authenticated/authenticated reader is determined based on whether the feedback information returned by the reader based on the tag code meets the authentication passing condition, and the target tag sequence of the electronic tag is sent to the reader after the reader is determined to be the authenticated/authenticated reader, so that the communication safety can be improved.

In some application scenarios, the electronic tag may send the tag code to the reader after receiving the verification information sent to the reader. After receiving the tag code, the reader queries preset information (for example, a string of characters "AABBC") stored corresponding to the tag code in a local storage or cloud storage based on the tag code, and sends the queried preset information corresponding to the tag code as feedback information to the electronic tag. And the electronic tag judges whether the preset information accords with the verification passing condition after receiving the preset information, and if the preset information accords with the verification passing condition, the electronic tag sends a target tag sequence of the electronic tag to the reader. For example, the electronic tag traverses whether the storage unit of the electronic tag has the same information as the preset information, and if the preset information is determined to exist, the preset information is determined to meet the verification passing condition.

In some application scenarios, the electronic tag may generate the random number r after receiving the verification information sent by the reader₁And a random sequence r₁And the tag code FID is sent to the reader. The reader receives the random number r₁After the tag code FID is compared with the tag code FID, the tag code FID is used for inquiring in local storage or cloud storage, and if the tag code FID is inquired, the verification operation is continued; if the tag code FID is not queried, then verification is stopped. After the reader inquires the tag code FID, the reader firstly generates a random sequence r₂And calculating according to the formula (1) and the formula (2) to obtain the value A and the value B.

Then, r is₁And the value of A | | B is used as feedback information and is sent 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).

D＝PUF(P_n) (3)

Wherein, P_nThe label represents a key unique to the signature in the nth round of authentication; p_n+1A value representing a key unique to the tag in the nth round of authentication (i.e., P)_n) The value of the key after being processed by a PUF (Physical Unclonable Functions) module. If the electronic tag determines that B and B' areAnd if not, determining that the feedback information meets the verification passing condition or the reader is an authenticated reader, and sending the target tag sequence of the electronic tag to the reader. And if not, determining 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.
