The positioning method based on the bluetooth beacon device provided by the specification can be applied to various scenes, for example, the positioning method based on the bluetooth beacon device provided by the specification can be applied to a takeaway delivery scene. In the prior art, a method for determining whether a distributor reaches a merchant is to determine a distance between a position reported by a terminal of the distributor and a position of the merchant, and when the distance is smaller than a preset distance threshold, it is determined that the distributor reaches the merchant.

As another example, the positioning method based on bluetooth beacon devices provided in this specification can be applied to shopping mall promotion scenarios. The shopping mall can be provided with the Bluetooth beacon device, the user can obtain the device identification, the running time, the decryption key and other information of the Bluetooth beacon device of the shopping mall from the server, when the user arrives at the shopping mall, the ciphertext information broadcasted by the Bluetooth beacon device of the shopping mall is received, the ciphertext information is decrypted by using the decryption key, the information such as the device identification, the running time and the like of the Bluetooth beacon device of the shopping mall contained in the ciphertext information is obtained, comparing the obtained device identification and running time with the decrypted device identification and running time, judging whether the user arrives at the market according to the comparison result, if so, receiving the promotion activity information of the market, otherwise, indicating that the Bluetooth beacon equipment of the market is possibly forged or maliciously used by competitors, an early warning message may be sent to the server so that the server determines whether the bluetooth beacon device of the merchant is forged or maliciously used.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a positioning system based on a bluetooth beacon device according to an embodiment of the present disclosure, and in fig. 1, the positioning system based on the bluetooth beacon device may include a bluetooth beacon device 101, a user terminal 102, and a server 103.
The Bluetooth Beacon (Beacon) device 101 may be a Bluetooth signal generating source based on a Bluetooth 4.0 communication protocol or Bluetooth Low Energy (BLE) technology. The bluetooth beacon device 101 may be formed by a bluetooth low energy communication module with a power supply, and broadcast a data packet (i.e., ciphertext information) through the bluetooth low energy communication module at preset intervals, where the ciphertext information may include information such as a device identifier of the bluetooth beacon device 101 and running time of the bluetooth beacon device 101, and of course, other information, for example, commodity sales promotion information, may be added to the ciphertext information according to actual needs. The bluetooth beacon device 101 may be placed in places such as shopping malls, parks, and the like. The ciphertext information broadcast by the bluetooth beacon device 101 may be determined according to the device identifier and the running time of the bluetooth beacon device 101, and meanwhile, the bluetooth beacon device 101 may also re-determine the ciphertext information according to the device identifier and the running time, and the like, according to the preset time interval, so that the ciphertext information broadcast by the bluetooth beacon device 101 dynamically changes.
In this specification, the bluetooth beacon apparatus 101 may be a bluetooth beacon apparatus that is not networked and connected to other apparatuses, and the bluetooth beacon apparatus 101 may not include a clock chip, that is, the bluetooth beacon apparatus 101 does not need to determine the time physically in seconds, in this case, the bluetooth beacon apparatus 101 may include a counter, where the counter is used for automatically counting when the bluetooth beacon apparatus 101 is powered on, and the automatic counting function of the counter may be implemented by program control or by a hardware circuit, so the running time of the bluetooth beacon apparatus 101 in this specification may include a count value of the counter. Compared with the prior art that the bluetooth beacon device needs to be connected with a server so that the server synchronizes a dynamic key to a user terminal, the bluetooth beacon device 101 in the present specification does not need to be connected with other devices or networked, and can determine whether the bluetooth beacon device 101 is forged or maliciously used while realizing the positioning of the user terminal by decrypting ciphertext information and processing the decrypted information through the user terminal.
Of course, the bluetooth beacon device 101 may also be a conventional bluetooth beacon device, i.e., a bluetooth beacon device that may be networked and/or connected to other devices.
The user terminal 102 may be an electronic device supporting a bluetooth 4.0 communication protocol, for example, a smart device such as a mobile phone and a tablet computer. When the user terminal 101 determines the target location to be reached, information of the bluetooth beacon device corresponding to the target location, for example, device identification, running time, decryption key and the like of the bluetooth beacon device corresponding to the target location, may be acquired from the server 103. When the user terminal 102 enters the bluetooth signal coverage area of the bluetooth beacon device corresponding to the target location, the user terminal 102 may receive the ciphertext information broadcast by the bluetooth beacon device 101, decrypt the ciphertext information according to the decryption key to obtain the device identifier, the running time and other information contained in the ciphertext information, compare the obtained device identifier with the decrypted device identifier, and compare the obtained running time with the decrypted running time, while implementing the positioning function of the user terminal 102, identify whether the bluetooth beacon device 101 is the bluetooth beacon device corresponding to the target location, when identifying that the bluetooth beacon device 101 is the bluetooth beacon device corresponding to the target location, the user terminal 102 may obtain the service corresponding to the target location, when identifying that the bluetooth beacon device 101 is not the bluetooth beacon device corresponding to the target location, the user terminal 102 may send an early warning message to the server 103, so that the server 103 performs a corresponding operation according to the warning message.
The server 103 may be a third party application platform, such as an order scheduling platform, etc., and may also be a device that manages the bluetooth beacon device 101. The server 103 stores the device identifier, the running time, the decryption key and the like of the bluetooth beacon device corresponding to the target position, wherein the server 103 can obtain the device identifier of the bluetooth beacon device corresponding to the target position in advance, determine the decryption key according to the device identifier of the bluetooth beacon device corresponding to the target position, initialize the running time of the bluetooth beacon device corresponding to the target position by the server 103, and update the running time after receiving the running time sent by the user terminal.
It should be noted that, in this specification, the bluetooth beacon device 101 may encrypt the information at a preset time interval to obtain ciphertext information and broadcast the ciphertext information, and does not need to connect to the server 103, that is, the bluetooth beacon device 101 does not need to perform data transmission with the server 103, and the user terminal 102 may perform data transmission with the server 103, receive the ciphertext information broadcast by the bluetooth beacon device 101, and decrypt the ciphertext information, thereby determining the positioning result.
Based on the positioning system based on the bluetooth beacon device shown in fig. 1, the embodiments of the present specification further provide a flowchart of a positioning method based on the bluetooth beacon device, as shown in fig. 2.
Fig. 2 is a flowchart of a positioning method based on a bluetooth beacon device according to an embodiment of the present disclosure, which may specifically include the following steps:
s200: the user terminal determines the target position to be reached.
In this specification, the target position determined by the user terminal may be expressed in different meanings in different application scenarios. For example, in a take-away delivery scenario, the target location may be a merchant identification such as a merchant number, merchant name, etc. in the take-away order. As another example, in a mall sales promotion scenario, the target location may be a location of a mall, and may also be a mall identifier such as a mall number, a mall name, and the like. That is, the target position in the present specification includes not only latitude and longitude position information in a narrow sense but also other uniquely representable information such as a logo.
S202: and sending a request for acquiring information corresponding to the target position to a server according to the target position.
S204: and receiving the device identification of the Bluetooth beacon device corresponding to the target position returned by the server according to the request as a first device identification, and a decryption key determined by the server in advance according to the first device identification.
After the user terminal determines the target position to be reached, the information corresponding to the target position can be obtained.
Specifically, the user terminal may send a request for obtaining information corresponding to the target location to the server according to the target location, after receiving the request sent by the user terminal, the server sends, to the user terminal, the device identifier of the bluetooth beacon device corresponding to the target location stored in the server as the first device identifier, the decryption key, and the running time as the first time, and the user terminal may receive the first device identifier and the decryption key sent by the server. The server may determine the decryption key in advance according to the first device identifier, initialize the running time of the bluetooth beacon device corresponding to the target location, and update the first time to the second time when the running time sent by the user terminal is received as the second time.
Therefore, the information corresponding to the target location may include information such as the first device identifier, the decryption key, and the first time.
S206: and if ciphertext information broadcasted by the Bluetooth beacon device is received, decrypting the ciphertext information according to the decryption key to obtain a device identifier contained in the ciphertext information as a second device identifier, wherein the ciphertext information is determined by the Bluetooth beacon device according to the second device identifier.
In this specification, a user terminal may receive ciphertext information broadcast by a bluetooth beacon device in real time, and a plurality of bluetooth beacon devices may also be placed in other locations, so that the user terminal may receive ciphertext information broadcast by each bluetooth beacon device in a polling manner, and decrypt the received ciphertext information according to a decryption key corresponding to the bluetooth beacon device corresponding to a target location acquired from a server to obtain information contained in the ciphertext, where the ciphertext information may include information such as a device identifier (i.e., a second device identifier) of the bluetooth beacon device, and an operation time (i.e., a second time) of the bluetooth beacon device.
Here, it needs to be explained that the bluetooth beacon device determines the ciphertext information according to the second device identifier and broadcasts the ciphertext information.
Specifically, first, the bluetooth beacon device may determine the encryption key based on the second device identification and the identification of the vendor of the bluetooth beacon device.
In this specification, the second device identifier may include information such as a mac (media Access Control address) address, a Serial Number (SN) code, and the second device identifier may uniquely determine one bluetooth beacon device, that is, the device identifiers of the bluetooth beacon devices are different. The server may set an identification for the vendor that provides the bluetooth beacon device, which may be represented as a Token (Token), i.e., Token differs for each vendor.
The bluetooth beacon device may determine the encryption key from the second device identification and the vendor's Token using a key generation algorithm. The bluetooth beacon device may input the second device identifier and Token of the vendor into the key generation algorithm to obtain the encryption key output by the key generation algorithm. The key generation Algorithm may be a Digest encryption Algorithm such as MD5 Message Digest Algorithm (Message Digest Algorithm MD5), Secure Hash Algorithm 1(Secure Hash Algorithm 1, SHA-1), or may be a custom key generation Algorithm that outputs a data length that matches an encryption key.
Then, the bluetooth beacon device may encrypt the second device identifier and the second time according to the encryption key to obtain the ciphertext information.
In this specification, the bluetooth beacon device may encrypt the second device identifier and the current running time of the bluetooth beacon device using a symmetric encryption algorithm to obtain the ciphertext information. The bluetooth beacon device may input the encryption key, the second device identifier, and the current running time into the symmetric encryption algorithm to obtain ciphertext information output by the symmetric encryption algorithm, where the ciphertext information includes the second device identifier, the second running time, and other information. The symmetric Encryption algorithm may be Advanced Encryption Standard (AES), Data Encryption Standard (DES), etc., and different symmetric Encryption algorithms may be selected according to the Data length of the Encryption key.
When the bluetooth beacon device is not networked or connected to other devices, a counter may be included in the bluetooth beacon device, and the second time may be a count value of the counter. Since the counter automatically counts when the bluetooth beacon device is powered on, when the bluetooth beacon device encrypts the second device identifier and the running time, the second time is the current count value determined by the counter.
The bluetooth beacon device may further encrypt the second device identifier and the second time at a preset time interval according to the encryption key, so as to obtain the ciphertext information. Therefore, the Bluetooth beacon device updates the ciphertext information and broadcasts the updated ciphertext information at preset time intervals.
S208: and determining a positioning result according to the first equipment identifier and the second equipment identifier.
After the ciphertext information is decrypted to obtain the second device identifier and the second time, the user terminal may determine whether the first device identifier is the same as the second device identifier. And if the judgment results are the same, determining a positioning result according to the first time and the second time, and if the judgment results are different, rejecting positioning.
Specifically, the user terminal may compare whether the first device identifier is identical to the second device identifier, and if the comparison result is identical, determine that the first device identifier is identical to the second device identifier, then obtain a running time of the bluetooth beacon device corresponding to the target location stored in the server as a first time, use the running time of the bluetooth beacon device included in the ciphertext information as a second time, determine whether the second time is less than the first time, that is, determine whether a count value obtained by decrypting the ciphertext information is less than a count value obtained from the server, if the determination result is less than the first time, refuse to perform positioning, if the determination result is not less than the second time, use the target location as a positioning result, and send the second time to the server, so that the server updates the first time to the second time, that is, sends the count value obtained by decrypting the ciphertext information to the server, so that the server updates the stored count value to the received count value.
If the comparison result is inconsistent, it is determined that the first device identifier is different from the second device identifier, which indicates that the scanned bluetooth beacon device (i.e., the bluetooth beacon device broadcasting the ciphertext information) is not the bluetooth beacon device corresponding to the target location, and therefore, the user terminal may refuse to locate.
It should be noted that, when the first device identifier is the same as the second device identifier and the second running time is less than the first running time, it is indicated that the bluetooth beacon device corresponding to the target location may be forged or maliciously used, so the user terminal may send the warning information to the server, so that the server performs a corresponding operation according to the warning information to determine whether the bluetooth beacon device at the target location is forged or maliciously used.
Based on the positioning system based on the bluetooth beacon device shown in fig. 1, the embodiment of this specification further provides another flowchart of a positioning method based on the bluetooth beacon device, as shown in fig. 3.
Fig. 3 is a flowchart of another positioning method based on a bluetooth beacon device according to an embodiment of the present disclosure, which may specifically include the following steps:
s300: and the server determines the device identification of the Bluetooth beacon device corresponding to the target position as the first device identification.
In this specification, through manners such as manual collection, the server may obtain a correspondence between each target location and the bluetooth beacon device, and for each target location, may determine a device identifier of the bluetooth beacon device corresponding to the target location, an identifier of a provider providing the bluetooth beacon device (that is, Token of the provider), and information such as a running time of the bluetooth beacon device. The server may use the device identifier of the bluetooth beacon device corresponding to the target location determined to be reached by the user terminal as the first device identifier, and use the running time of the bluetooth beacon device corresponding to the target location determined to be reached by the user terminal as the first time.
S302: and determining a decryption key according to the first equipment identifier.
The server may determine a decryption key from the first device identification and the vendor Token using a key generation algorithm. The server may input the first device identifier and the Token of the vendor into the key generation algorithm to obtain the decryption key output by the key generation algorithm.
As can be seen from the above, the bluetooth beacon device obtains the ciphertext information by using a symmetric encryption algorithm, so the decryption key determined by the server is the same as the encryption key determined by the bluetooth beacon device, and the key generation algorithm used by the server to generate the decryption key is the same as the key generation algorithm used by the bluetooth beacon device to generate the encryption key.
S304: and receiving a request sent by the user terminal according to the target position.
S306: and returning the first equipment identifier and the decryption key to the user terminal according to the request, so that the user terminal decrypts the received ciphertext information broadcast by the bluetooth beacon equipment according to the decryption key to obtain an equipment identifier contained in the ciphertext information as a second equipment identifier, and determines a positioning result according to the first equipment identifier and the second equipment identifier, wherein the target position is a position to be reached determined by the user terminal, and the ciphertext information is determined by the bluetooth beacon equipment according to the second equipment identifier.
When receiving a request sent by the user terminal according to the target position, the server can send information such as the first device identifier, the decryption key, the first time and the like to the user terminal, so that the user terminal decrypts the received ciphertext information broadcast by the Bluetooth beacon device according to the decryption key, and obtains the device identifier contained in the ciphertext information as the second device identifier and the running time contained in the ciphertext information as the second time.
After determining that the first device identifier is consistent with the second device identifier, the user terminal can judge whether the second time is less than the first time, and when the judgment result is less than the first time, the user terminal can send early warning information to the server. And when the judgment result is not less than the first time, the user terminal can send the second time to the server.
If the server receives the warning information sent by the user terminal, corresponding operations can be executed according to the warning information to judge whether the bluetooth beacon device at the target position is forged or maliciously used, for example, in a takeaway distribution scene, the server can judge whether at least two warning messages about the bluetooth beacon device corresponding to a merchant in the takeaway order are received, if yes, the bluetooth beacon device corresponding to the merchant in the takeaway order is judged to be possibly forged or maliciously used, and the takeaway order is processed.
If the server receives the second time sent by the user terminal, the first time stored in the server can be deleted, and the second time is stored, that is, the first time is updated to the second time.
Based on the above-mentioned positioning method based on bluetooth beacon device, an interaction flow diagram of the positioning method based on bluetooth beacon device is also provided in the embodiments of the present specification, as shown in fig. 4.
Fig. 4 is an interaction flowchart of a positioning method based on a bluetooth beacon device according to an embodiment of the present disclosure.
In fig. 4, the bluetooth beacon device may determine an encryption key by using a key generation algorithm according to the device identifier of the bluetooth beacon device and the identifier of the provider that provides the bluetooth beacon device and is preset by the server, and then encrypt the device identifier of the bluetooth beacon device and the running time at a preset time interval by using a symmetric encryption algorithm according to the encryption key to obtain ciphertext information, and broadcast the ciphertext information. The running time of the bluetooth beacon device may be a count value that a counter of the bluetooth beacon device automatically counts when the bluetooth beacon device is powered on.
For convenience of description, the device identifier of the bluetooth beacon device corresponding to the target location stored in the server is taken as the first device identifier, and the runtime of the bluetooth beacon device stored in the server is taken as the first time. The server may generate a decryption key using a key generation algorithm based on the first device identification and the identification of the vendor.
The user terminal determines a target position to be reached, sends a request for acquiring information corresponding to the target position to the server according to the target position, and after receiving the request, the server sends information such as a first device identifier, a decryption key and first time to the user terminal.
And after the user terminal receives the ciphertext information broadcast by the Bluetooth beacon device, decrypting the ciphertext information according to the decryption key to obtain the device identifier of the Bluetooth beacon device, the running time of the Bluetooth beacon device and other information contained in the ciphertext information. The user terminal can judge whether the first equipment identification is the same as the second equipment identification, if the judgment result is different, the ciphertext information received by the user terminal is not the ciphertext information broadcasted by the Bluetooth beacon equipment corresponding to the target position, if the judgment result is the same, the user terminal can judge whether the second time is less than the first time, if the judgment result is less than the first time, the user terminal refuses to position, the early warning information can be sent to the server, so that the server executes corresponding operation according to the early warning information, judges whether the Bluetooth beacon equipment at the target position is forged or maliciously used, if the judgment result is not less than the second time, the user terminal can take the target position as the positioning result and send the second time to the server, so that the server updates the first time to the second time.

Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium that stores computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component.
