In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Fig. 1 is a schematic application environment of a data verification method for near field communication according to an embodiment. As shown in fig. 1, the application environment includes an electronic device 200 provided with at least two NFC antennas 100 and a reader 300, where the electronic device 200 may implement data exchange with the reader through NFC communication via the NFC antennas. The electronic equipment can be terminal equipment such as a mobile phone, a tablet personal computer, a handheld terminal, a telephone watch and the like; the reader-writer can be a reader-writer of an access control system, an elevator reader-writer and the like.
Fig. 2 is a flow diagram of a data verification method for near field communication in one embodiment. The data verification method of near field communication in this embodiment is described by taking the electronic device operating in fig. 1 as an example. As shown in fig. 2, the method includes:
s101, when the electronic equipment approaches the reader for multiple times, determining a target NFC antenna closest to the reader under each approach scene.
The electronic device may include an NFC chip and at least two NFC antennas. The NFC antenna can be used for sending data sent by the NFC chip to the reader-writer and can also be used for receiving data sent by the reader-writer. The NFC antenna may be a single-ended antenna or a differential antenna. The electronic device may include two NFC antennas, or may include three or four NFC antennas, which is not limited herein. The positions of the at least two NFC antennas may be different, for example, the electronic device includes four NFC antennas, and the four NFC antennas may be located at upper left, lower left, upper right, and lower right positions of the rear housing of the electronic device, respectively. Optionally, the electronic device includes a first NFC antenna and a second NFC antenna, and the first NFC antenna and the second NFC antenna are respectively located at the top and the bottom of the electronic device housing.
The at least two NFC antennas may be connected to the same NFC chip, or may be connected to different NFC chips, and the different NFC chips may be in communication connection with each other.
The NFC chip in the electronic device may operate in a reader/writer operating mode, that is, the NFC chip in the electronic device may read data in the NFC tag or write data into the NFC tag; the NNFC chip can also work in a card simulation working mode, namely, the electronic equipment integrated with the NFC chip is simulated into an NFC label or a non-contact card, for example, a mobile phone integrated with the NFC chip and an NFC antenna can be used as an access card. When the NFC chip works in the card simulation mode, the electronic equipment can be subjected to security verification before data exchange is carried out between the electronic equipment and the reader-writer, so that the use security of the electronic equipment is guaranteed. In the above scenario that the electronic device communicates with the reader/writer, the electronic device may communicate with the reader/writer after contacting the electronic device, or may communicate with the reader/writer without contacting the electronic device. In a scene where the electronic device communicates with the reader/writer, the electronic device may be in a power-on state or a power-off state.
When the user uses the electronic equipment as the NFC label, the electronic equipment and the reader-writer can be approached for multiple times, so that the electronic equipment can acquire the security verification code to perform security verification. The number of times that the electronic device and the reader/writer approach may be a preset number, for example, the preset number is 4 times, 5 times, and the like, and the specific value of the preset number is not limited herein. In addition, the preset times may be determined based on the number of NFC antennas in the electronic device, and the preset times may be equal to or greater than the number of NFC antennas in the electronic device; the preset times can be in a multiple relation with the number of the NFC antennas, when the number of the NFC antennas is small, the multiple numerical values can be large, and when the number of the NFC antennas is large, the multiple numerical values can be small. In addition, the preset number of times may be in a non-multiple relationship with the number of NFC antennas, for example, the electronic device includes 2 NFC antennas, and the preset number of times is 3. In one implementation, the preset number of times may be set by the user. For example, when the electronic device includes 2 NFC antennas, the preset number of times may be 4 or 6; when the electronic device includes 4 NFC antennas, the preset number of times may be 4 or 8.
When the preset times of the multiple approaches is N, the electronic equipment can acquire the security verification code and perform security verification when approaching the reader for the Nth time; or, the electronic device may further obtain the security verification code when approaching the reader/writer for the (N + 1) th time, which is not limited herein.
The security verification code is related to the sequence of the at least two NFC antennas approaching the reader-writer. The security verification code can be obtained based on the approaching sequence of the NFC antenna approaching the reader-writer, and can also be obtained based on the reverse sequence of the approaching sequence; or, the electronic device may further generate a security verification code corresponding to the sequence of the NFC antenna according to a preset encoding rule, and an acquisition manner of the security verification code is not limited herein. For example, the NFC antennas include a first NFC antenna ANT1 and a second NFC antenna ANT2, ANT1 approaches the reader in a first approach scenario, ANT2 approaches the reader in a second approach scenario, and ANT2 approaches the reader in a third approach scenario; that is to say the order of NFC antennas is ANT1, ANT2, ANT 2; the security verification code can be obtained by coding according to ANT1, ANT2 and ANT2 in sequence, or can be obtained by coding according to ANT2, ANT2 and ANT 1; it is also possible to place ANT1 in the first-time-close scene at the middle position of the security coding and place ANT2 in the second-time-close scene at the start position of the security coding according to preset rules, that is, obtained based on the sequential ANT2, ANT1, ANT2 coding.
In the process that the electronic device approaches the reader/writer each time, the electronic device may determine which NFC antenna is closest to the reader/writer at present, and determine that the NFC antenna is the target NFC antenna in the approach scene at this time. The electronic device may be determined according to signal quality of signals received by different NFC antennas, or may be determined according to magnitude of induced current generated by different NFC antennas through electromagnetic induction, which is not limited herein.
S102, determining a safety verification code of the electronic equipment according to a target NFC antenna in a scene close to each time and a preset mapping relation; the mapping relationship includes a corresponding relationship between different NFC antennas and different authentication marks.
After determining that the target NFC antenna is close to the scene each time, the electronic device may determine the security verification code according to the target NFC antenna and the preset mapping relationship. The mapping relationship includes a corresponding relationship between different NFC antennas and different authentication marks. The verification mark may be represented by a number, a character, or a position of an antenna, which is not limited herein. When the verification mark is represented by a number, the verification mark may be represented by a binary number, and the number of bits of the verification mark corresponding to each NFC antenna may be determined by the number of NFC antennas in the electronic device. The electronic device includes two NFC antennas, and the authentication mark may be represented by a 1-bit binary number, for example, "0" may be used as the authentication mark of the first NFC antenna, and "1" may be used as the authentication mark of the second NFC antenna. In another embodiment, four NFC antennas are included in the electronic device, and the authentication mark may be represented by a 2-bit binary number, for example, "00" may be used as the authentication mark of the first NFC antenna.
The electronic device may determine the security verification code according to the target antenna and the mapping relationship of each approach after multiple approaches. Or, the electronic device may determine, in each approaching scene, the corresponding verification mark of the current approaching scene respectively. After determining the verification mark of the target NFC antenna, the electronic device may write the verification mark into a register in each approach scenario. The electronic device may write the verification flag of the first approaching scene into the highest bit of the register, may also write the lowest bit of the register, and may also write the storage location corresponding to the first approaching scene, which is not limited herein. Optionally, the electronic device may determine, based on the mapping relationship, a verification mark corresponding to the target NFC antenna in the scene of each approach; and arranging the verification marks according to the time sequence of each time of approaching the scene to obtain the security verification code.
Taking the electronic device shown in fig. 3 as an example, the electronic device includes two NFC antennas, ANT1 and ANT2, ANT1 is located at an upper portion of the back of the electronic device, and ANT2 is located at a lower portion of the back of the electronic device. The user has set the password "0110" in the electronic device. In the mapping relationship, the validation flag corresponding to ANT1 is 0, and the validation flag corresponding to ANT2 is 1. In each approach scene, the electronic device writes the authentication tag of the target NFC antenna closest to the electronic device into the register according to the order from high to low, and when the NFC antenna of the mobile phone approaches the reader and is ANT1, ANT2, ANT2, and ANT1 respectively, the result in the register is "0110". In the fourth approach scenario, the electronic device reads the value in the register to obtain the security verification code "0110".
S103, carrying out security verification on the electronic equipment according to the security verification code and a preset password.
A password is preset in the electronic equipment, and the password corresponds to a preset NFC antenna approaching sequence. The password may be set by the user through an application program and stored in the electronic device. When the security verification code is matched with the preset password, the electronic equipment passes the security verification; when the security verification code is not matched with the preset password, the electronic equipment cannot pass the security verification. When the electronic equipment matches the security verification code with the password, data conversion can be respectively carried out on the security verification code and the password, and if the converted data are the same, the security verification code is considered to be matched with the preset password. Optionally, the electronic device may perform a bit-wise comparison of the security verification code with a preset password; if each bit of the security verification code is the same as that of the preset password, determining that the security verification of the electronic equipment is passed; and if the safety verification code and the preset password have different bits, determining that the safety verification of the electronic equipment does not pass.
The user of the electronic equipment can swipe the card by adopting the preset NFC antenna approaching sequence, so that different NFC antennas approach the reader-writer in sequence, and the security verification code obtained by the electronic equipment is matched with the preset password and passes the security verification.
When other users illegally use the electronic device, the preset approaching order is not clear, but the NFC antenna is randomly brought close to the reader/writer. When the number of times of the other users approaching the electronic equipment to the reader-writer is smaller than the preset number of times, the electronic equipment cannot acquire the security verification code, or the number of bits in the acquired security verification code is smaller than the preset password, so that the security verification code is not compared with the preset password, the electronic equipment is directly determined not to pass the security verification, and the electronic equipment cannot exchange data with the reader-writer. When the number of times of approaching the electronic device to the reader-writer by other users is greater than or equal to the preset number of times and the security verification code obtained by the electronic device is not matched with the preset password, the electronic device cannot pass the security verification and cannot exchange data with the reader-writer. The above security authentication process may be as shown in fig. 4, and includes the following steps:
s201, obtaining the approaching times of the electronic equipment and the reader-writer;
s202, determining whether the approaching times are greater than or equal to preset times; if the approaching times are less than the preset times, executing S203; if the approaching times are greater than or equal to the preset times, executing S204;
s203, determining that the electronic equipment does not pass the safety verification;
s204, comparing the security verification code with a preset password according to the bit to determine whether each bit is the same; if yes, executing S205, otherwise, returning to executing S203;
s205, determining that the electronic equipment passes the safety verification.
In the data verification method of near field communication, the electronic device comprises at least two NFC antennas; when the electronic equipment approaches the reader-writer for multiple times, the electronic equipment determines a target NFC antenna closest to the reader-writer in an approach scene each time; then, acquiring a security verification code of the electronic equipment according to the target NFC antenna in each approaching scene and a preset mapping relation; finally, according to the safety verification code and a preset password, carrying out safety verification on the electronic equipment; the mapping relationship includes a corresponding relationship between different NFC antennas and different authentication marks. The electronic equipment determines the target NFC antenna closest to the reader-writer in the approaching scene each time, so that the NFC antenna approaching sequence when the electronic equipment block approaches the reader-writer by a user can be obtained; furthermore, the electronic device determines the security verification code according to the target NFC antenna and the preset mapping relation, so that the obtained security verification code is not matched with the password under the condition that the user does not approach the electronic device and the reader-writer according to the preset approaching sequence, the electronic device and the reader-writer cannot exchange data, and the security of the electronic device is guaranteed; in addition, the data verification method can be executed through an NFC chip in the electronic equipment, so that the use safety of the electronic equipment can be ensured under the condition that the electronic equipment is started or shut down.
Fig. 5 is a schematic flowchart of a data verification method for near field communication in another embodiment, where this embodiment relates to a manner in which an electronic device determines a target NFC antenna, and based on the above embodiment, as shown in fig. 5, the above S101 includes:
s301, acquiring voltage amplitudes output by each receiving end of the electronic equipment under each approaching scene; wherein, one receiving end corresponds to one NFC antenna.
When the electronic device determines the target NFC antenna closest to the reader/writer, the determination may be made according to the amplitude of the voltage output by the receiving terminal. In the electronic device, each receiving end corresponds to one NFC antenna, and after the NFC antenna receives an instruction sent by the reader, a voltage value may be output at the receiving end. The electronic device can write the voltage amplitude output by each receiving end in each approaching scene into the voltage register.
S302, determining the NFC antenna corresponding to the receiving end with the maximum voltage amplitude as a target NFC antenna.
On the basis of the above steps, when the electronic device determines the target NFC antenna, the maximum voltage amplitude may be determined by reading the voltage amplitudes of the receiving ends corresponding to different NFC antennas in the voltage register, and then comparing the voltage amplitudes of the NFC antennas. Further, the electronic device may determine, as the target NFC antenna, the NFC antenna to which the receiving end corresponding to the maximum voltage amplitude is connected.
According to the data verification method for near field communication, the electronic equipment can quickly judge the target NFC antenna closest to the reader-writer through the voltage amplitude of the receiving end, and the efficiency and accuracy of safety verification of the electronic equipment are improved.
In an embodiment, on the basis of the above embodiment, when the security verification of the electronic device passes, the electronic device sends data to be sent to the reader through the target NFC antenna in the last approach scene. Continuing with the example of the electronic device in fig. 3, when the electronic device approaches the reader/writer for the fourth time, the security verification passes, and the target NFC antenna ANT1 that approaches the reader/writer for the fourth time may be used as an antenna for sending data, and the data to be sent is sent to the reader/writer through the antenna.
According to the data verification method for near field communication, the electronic equipment selects the target NFC antenna closest to the reader-writer to transmit data, so that the reader-writer can receive a stronger signal, and the transmission reliability of data to be transmitted is improved.
In one embodiment, on the basis of the above embodiment, in the case that the electronic device fails the security verification, a card swiping again instruction can be sent to the user; the card swiping again indication is used for indicating a user to enable the electronic equipment to be close to the reader-writer.
The electronic equipment can prompt the user to swipe the card again under the condition that the safety verification fails; the prompt mode may be a voice prompt or a vibration prompt, and is not limited herein. After receiving the card swiping again instruction, the user can approach the card again according to the preset approaching sequence of the NFC antenna, so that the electronic equipment can return to execute the step of obtaining the security verification code to perform security verification.
According to the data verification method of the near field communication, the electronic equipment sends the card swiping again instruction to the user under the condition that the safety verification is not passed, so that the situation that the card swiping of the user is failed can be avoided, the card swiping is not determined to be completed for several times in the safety verification process, the user can conduct the card swiping in order according to the preset NFC antenna approaching sequence after the card swiping again instruction, and the card swiping success rate is improved.
