In the embodiment of the present invention, the NFC authentication device may be an NFC card reading device (such as a card reader). The execution subject of the information verification method can be a card reader, and can also be other electronic equipment comprising the card reader.

In this embodiment of the present invention, at least one NFC module may be disposed in the terminal device.

The embodiment of the invention provides an information verification method, wherein in a preset time length, terminal equipment can send NFC verification information to an NFC verification device based on at least one NFC module of the terminal equipment, and the NFC verification information is obtained based on a plurality of pieces of NFC label information sent by the at least one NFC module; and when the NFC verification information is matched with the preset verification information, the NFC verification information is used for indicating that the NFC verification device passes the verification.

(1) the terminal equipment is provided with an NFC module, and the terminal equipment reads the NFC label information from the NFC module for multiple times so as to acquire the multiple NFC label information.

For example, it is assumed that an NFC module is provided in the terminal device, which is denoted as NFC0, and Tag information (Tag) of NFC0 may be denoted as "0". When the terminal equipment carries out NFC verification, if the antenna of NFC0 in the terminal equipment approaches the card reader for 3 times within the preset time, the card reader reads 0 every time, and therefore 3 0's can be obtained.

Further, according to 3 "0" s obtained after 3 times of reading, the NFC authentication information "000" can be determined.

(2) The terminal equipment is provided with a plurality of NFC modules, and the terminal equipment reads NFC label information from the same NFC module of the plurality of NFC modules for a plurality of times so as to acquire the plurality of NFC label information.

For example, assuming that n +1 NFC modules, NFC0 and NFC1 … … NFCn, are provided in the terminal device, the terminal device reads NFC tag information in an NFC module, NFC0, multiple times.

Illustratively, two NFC modules, NFC0 and NFC1, are included in the terminal device, where Tag information (Tag) of NFC0 may be denoted as "0" and Tag information of NFC1 may be denoted as "1". When the terminal device performs the NFC verification, if the antenna of the NFC0 in the terminal device approaches the card reader for 3 times within a preset time period, and the antenna of the NFC1 does not approach the card reader, then the card reader reads "0" for 3 times, so that 3 "0" s can be acquired.

(3) The terminal equipment is provided with a plurality of NFC modules, and the terminal equipment reads NFC label information from different NFC modules in the plurality of NFC modules one time or a plurality of times so as to acquire the plurality of NFC label information.

For example, assuming that n +1 NFC modules, NFC0 and NFC1 … … NFCn, are provided in the terminal device, the terminal device reads NFC tag information 1 time in an NFC module of NFC0, and reads NFC tag information 2 times in an NFC module of NFC 1.

Illustratively, the terminal device includes two NFC modules, NFC0 and NFC1 respectively, and when the terminal device performs NFC authentication, if within a preset time period, an antenna of NFC0 in the terminal device first approaches the card reader, and then an antenna of NFC1 approaches the card reader, so that the card reader reads "0" and "1" of Tag in turn.

Further, according to the order of "0" and "1" obtained after 2 readings and the order of "0" and "1", it can be determined that the NFC authentication information is "01".

The information verification method, the information verification device and the storage medium provided by the embodiment of the invention can be applied to various scenes.

Optionally, the method provided by the embodiment of the invention can be applied to some access control system scenes to perform user identity authentication so as to open an access control or close the access control.

Optionally, the information verification method provided in the embodiment of the present invention may also be applied to a mobile payment scenario, and the information verification method provided in the embodiment of the present invention may be used to perform user identity verification, so as to improve payment security and protect property security of a mobile terminal user.

Example one

Corresponding to the step (3), the NFC tag information is read from the NFC modules in the terminal device, and the antennas of different NFC modules are spaced by a preset distance.

The embodiment of the invention provides terminal equipment provided with two or more NFC modules.

Exemplarily, as shown in fig. 1b, a schematic diagram of a terminal device provided with two NFC modules is shown. A first NFC module 21 and a second NFC module 22, respectively. The NFC chips and the antennas are two independent sets, the first NFC module 21 includes a first NFC chip 211 and a first NFC antenna 212, the first NFC antenna 212 is disposed above the terminal device (near a first edge of the mobile phone), the second NFC module 22 includes a second NFC chip 221 and a second NFC antenna 222, and the second NFC antenna 222 is disposed below the terminal device (near a second edge, the second edge is disposed opposite to the first edge). Since NFC belongs to near field communication, the antenna positions of the first NFC antenna 212 and the second NFC antenna 222 are separated by a certain distance, and thus, the corresponding antennas can be accurately identified.

Optionally, since NFC belongs to near field communication, a working distance (i.e., a communication distance) of the NFC antenna of the mobile phone is usually about 4cm, and optionally, the antenna positions of the first NFC antenna 212 and the second NFC antenna 222 shown in fig. 1b may be separated by a distance of more than 4cm (e.g., 5cm or 6cm), so that the corresponding antennas can be accurately identified.

NFC belongs to short-distance communication, and the communication distance of the NFC of the current mobile phone is about 4cm, so that two antennas can be distinguished as long as the two antennas are separated by a certain distance.

Optionally, the preset distance is determined according to a communication distance of the NFC module.

Optionally, the preset distance is greater than or equal to the communication distance of the terminal device.

Because the NFC belongs to near field communication, the antenna positions of different NFC modules are separated by a certain distance, and the corresponding antenna can be accurately identified.

NFC belongs to short-range communication, and the communication distance of the NFC of the current mobile phone is about 4cm, so that two antennas can be distinguished as long as the two antennas are separated by a certain distance.

As shown in fig. 2a, an embodiment of the present invention provides an information verification method, where the method includes:

201. and acquiring a plurality of pieces of NFC label information from the terminal equipment within a preset time.

Wherein different NFC modules can be provided with different NFC tag information.

Alternatively, it is assumed that, in the terminal device as described in fig. 1b, the Tag information (Tag) of the first NFC module 21 may be marked as "0", and the Tag information of the second NFC module 22 is marked as "1". Correspondingly, when the terminal device performs NFC authentication, if the antenna of the NFC0 in the terminal device is close to the card reader, the card reader reads the Tag of the first NFC module 21, which is marked as "0"; if the antenna of the second NFC module 22 in the terminal device is close to the card reader, the card reader reads Tag of the first NFC module 21, which is recorded as "1".

Optionally, the 201 may be implemented by the following 201a to 201 c:

and 201a, reading the NFC label information from the NFC module of the terminal equipment for multiple times within a preset time length to obtain multiple pieces of NFC label information to be selected.

201b, obtaining signal intensities corresponding to the received multiple pieces of information of the NFC tags to be selected respectively when the multiple pieces of information of the NFC tags to be selected are read.

201c, determining a plurality of pieces of NFC tag information from the plurality of pieces of NFC tag information to be selected so as to obtain NFC verification information including the plurality of pieces of NFC tag information, wherein the signal intensity of the plurality of pieces of NFC tag information is greater than the preset intensity.

The multiple pieces of information of the NFC tag to be selected may be obtained by the card reader multiple times, where the number of the pieces of information of the NFC tag to be selected obtained each time may be one or more.

The above-mentioned 201a to 201c may include two possible cases when being implemented specifically:

the first possible scenario is: for the case that the number of the to-be-selected NFC tag information acquired each time is multiple, the card reader may select the to-be-selected NFC tag information with the strongest signal strength after acquiring the multiple pieces of to-be-selected NFC tag information, and then determine the to-be-selected NFC tag information with the strongest signal strength acquired multiple times as the multiple pieces of NFC tag information.

For example, NFC tag information is acquired 2 times in total, and 3 pieces of NFC tag information to be selected are acquired each time, then first target NFC tag information with the strongest signal strength may be determined from the 3 pieces of NFC tag information to be selected acquired for the first time, second target NFC tag information with the strongest signal strength may be determined from the 3 pieces of NFC tag information to be selected for the second time, and then the first target NFC tag information and the second target NFC tag information are determined as NFC tag information.

The second possible scenario is: the card reader can select a plurality of pieces of NFC label information to be selected, the signal intensity of which is greater than the preset intensity, from all pieces of NFC label information to be selected acquired for multiple times, and then determines the plurality of pieces of NFC label information to be selected as the plurality of pieces of NFC label information.

For example, NFC tag information is acquired 2 times in total, and 3 pieces of NFC tag information to be selected are acquired each time, then first target NFC tag information and second target NFC tag information having signal strength greater than a preset strength may be determined from 6 pieces of NFC tag information to be selected acquired twice, and then the first target NFC tag information and the second target NFC tag information may be determined as NFC tag information.

Due to the limited space of the terminal device, under the condition that a plurality of NFC modules may be arranged, when a certain NFC module (hereinafter referred to as a first NFC module) in the terminal device approaches a card reader to perform NFC authentication, the card reader not only receives tag information of the first NFC module, but also receives tag information of other NFC modules except the first NFC module.

In an optional implementation manner, because in the process of performing NFC authentication by using a certain NFC module (hereinafter referred to as a first NFC module) in the terminal device to approach the card reader, the first NFC module is closest to a device in the card reader for reading NFC, and other NFC modules are farther from the device in the card reader for reading NFC, the card reader may filter the acquired multiple pieces of tag information by using a principle that the closer the distance is, the stronger the signal strength is, so as to determine the tag information actually performing NFC authentication.

For example, it is assumed that 4 pieces of NFC tag information to be selected, namely tag information a, tag information b, tag information c, and tag information d, are acquired, and signal strengths when the 4 pieces of tag information are read are different, as shown in table 1.

TABLE 1

Information of NFC tag to be selected	Signal strength
		Tag information a	100
Tag information b	80
		Tag information c	60
Label information d	110

If the preset strength is 100, two pieces of first tag information may be deleted from the 4 pieces of NFC tag information to be selected, which are tag information a and tag information d, respectively.

Further, the tag information a and the tag information b may be used for subsequent NFC authentication procedures.

According to the implementation mode, the plurality of pieces of NFC label information with the signal intensity larger than the preset intensity can be screened out from the acquired plurality of pieces of NFC label information to be selected, so that more accurate NFC label information to be verified can be screened out, the acquired more accurate NFC verification information is used for NFC verification, and the accuracy in the use of an NFC card simulation function is improved.

In another optional implementation manner, when the terminal device is close to the card reader, the terminal device may display a plurality of analog cards corresponding to different NFC modules provided in the terminal device when the card reader is detected, so that the user can select the analog cards, and determine NFC tag information that the user wants to be read by the card reader in response to a selection operation of the user on the analog cards.

As shown in fig. 2b, it is an interface diagram of a terminal device, in which a plurality of emulated cards in the terminal device are displayed, including an NFC card 1, an NFC card 2, and an NFC card 3.

Further, after the user clicks the display area where the NFC card 1 is located in the interface diagram shown in fig. 2b, the interface of the terminal device may be switched and displayed to the interface shown in fig. 2c, in the interface, the NFC card 1 is highlighted (enlarged and displayed), and the other cards are reduced and displayed to indicate that the current card is the NFC card 1.

The NFC tag information corresponding to each card is different, for example, the NFC tag information corresponding to the NFC card 1 is "00", the NFC tag information corresponding to the NFC card 2 is "01", and the NFC tag information corresponding to the NFC card 3 is "11". When the method provided by the embodiment of the invention is adopted for NFC verification, a user can select the NFC card 1 firstly so that the card reader can read '00', then the user can switch to select the NFC card 2 so that the card reader can read '01', then NFC verification information '0001' is obtained according to '00' and '01', and is compared with preset verification information, '0001' and the preset verification information, and when the '0001' is matched with the preset verification information, the NFC verification is determined to be passed, and when the '0001' is not matched with the preset verification information, the NFC verification is determined to be failed.

According to the implementation mode, the NFC label information to be verified can be accurately selected through input of the user, the more accurate label information is acquired and used for NFC verification, and accuracy in the process of using an NFC card simulation function is improved.

202. A reading order for reading the information of the plurality of NFC tags is acquired.

203. And determining the NFC verification information according to the plurality of pieces of NFC label information and the reading sequence of the plurality of pieces of NFC label information.

Illustratively, two NFC modules, NFC0 and NFC1, are included in the terminal device. Assuming that the order of reading the tag information of NFC0 and the tag information of NFC1 is, first NFC0 and then NFC1, it may be determined that the NFC verification information is "01"; assuming that the order of reading the tag information of NFC0 and the tag information of NFC1 is NFC1 and then NFC0, it can be determined that the NFC authentication information is "10".

204. And comparing the NFC authentication information with preset authentication information.

If the NFC authentication information is consistent with the preset authentication information, the following is performed 105; if the NFC authentication information is not consistent with the preset authentication information, the following procedure 106 is performed.

In the embodiment of the invention, a password (namely the preset verification information) can be preset in the card reader, and the card reader compares the NFC verification information determined according to the NFC0 and NFC1 reading sequence with the preset password for verification, so that the password verification of card simulation is realized.

In the embodiment of the invention, as the card reader cannot identify whether the terminal equipment is in the power-off state or the power-on state, the password authentication is required no matter the terminal equipment is in the power-off state or the power-on state as long as the password is preset by the card reader.

Alternatively, the preset verification information may be a combination of a plurality of pieces of tag information, or an information combination indicating the plurality of pieces of tag information.

Optionally, the number of bits of the preset password may be set arbitrarily.

Under the condition of ensuring certain security, the less the password digit is set, the more convenient and faster the NFC verification process is. In order to verify the label informativeness of the process, a smaller number of secret code bits can be set so as to ensure the convenience of use while representing the security.

For example, assuming that a 4-bit authentication password is preset in the card reader as "0110", the terminal device includes two NFC modules, NFC0 and NFC1 respectively. The card simulation password verification process of the card reader and the terminal device may be as follows, when the NFC tag information read by the card reader is sequentially the tag information of "NFC 0", "NFC 1" and "NFC 0", as shown in the above related examples, the tag information of "0", "1", "0" may be obtained respectively, further, according to the read sequence, the NFC verification information of "0110" may be obtained, the NFC verification information is compared with the preset password, and then the two are identical, and the NFC verification passes. And other terminal equipment swipes the card in sequence, and the obtained label information is inconsistent with the preset password and is judged to be not passed through the NFC verification.

205. Determining that the NFC authentication device is authenticated.

When the information verification method in the embodiment of the invention is applied to an access control system, the NFC verification is passed, and the access control system allows the access control to be opened.

206. Determining that the NFC authentication device fails authentication.

The information verification method in the embodiment of the invention is applied to the access control system, the NFC verification ratio is passed, and the access control system does not allow the access control to be opened.

After 206, 201 may return to execution.

In the embodiment of the invention, through the terminal equipment provided with the plurality of NFC modules, the reading sequence of two or more NFC modules is compared with the preset password of the card reader within a certain time by utilizing the card reader, so that the password verification of the NFC card simulation function is realized, and the safety when the NFC card simulation function is used is improved.

Example two

Corresponding to the cases (1) and (2) above, the plurality of pieces of NFC tag information are read from the same NFC module in the terminal device.
