[0062] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0063] The information display method provided in this application embodiment can be applied to, for example, Figure 1 The information display system 100 shown includes a target card 110, a mobile terminal 120, and a server 130. The target card 110 integrates an NFC (Near Field Communication) chip and a power-on coil. The target card 110 and the mobile terminal 120 are brought close together and interact with each other via NFC technology. The mobile terminal 120 and the server 130 communicate via a network. The mobile terminal 120 can be, but is not limited to, various smartphones and tablets. The server 130 can be a standalone server or a server cluster consisting of multiple servers.

[0064] In one embodiment, such as Figure 2 As shown, an information display method is provided, which can be applied to... Figure 1 Taking target card 110 (hereinafter referred to as target card) as an example, the explanation includes the following steps:

[0065] Step 202: Obtain the first URL from the mobile terminal, and concatenate the first URL with the preset service interface address to obtain the target address.

[0066] The target card has a pre-set service interface address, which is used to identify the first URL.

[0067] In implementation, when a user needs to use the target card's number, the user must first log in to the first website address via their mobile terminal. Then, the mobile terminal displays the first website address. After the first website address is displayed, the user brings the target card close to the mobile terminal. Then, using NFC technology, the target card retrieves the first website address from the mobile terminal. The target card then concatenates the first website address with a preset service interface address to obtain the target address.

[0068] Step 204: Construct first information based on the target address and the feature information corresponding to the preset target card.

[0069] The first piece of information is used to instruct the server to determine the service result.

[0070] In implementation, the target card is pre-set with its corresponding feature information. This feature information includes the serial number of the NFC chip within the target card. The target card constructs first information based on the target address and the serial number. Then, using NFC technology, the target card sends this first information to the mobile terminal. Upon receiving the first information, the mobile terminal sends it to the server based on the target address contained within it.

[0071] Step 206: Receive the service result transmitted by the server. If the service result meets the preset display conditions, display the card number based on the service result.

[0072] The specific content of the displayed condition is that the service result is the first result.

[0073] In implementation, the target card has pre-set display conditions. The target card obtains the service result transmitted by the server. The target card determines whether the service result is the first result. If the service result is the first result, the target card displays its card number based on the service result.

[0074] In the above information display method, the service result is determined based on the constructed first information, and the card number is displayed when the service result meets the display conditions. This ensures that the card number can only be displayed when the display conditions are met, thereby protecting privacy information and improving the security of information display.

[0075] In one embodiment, after the first information is constructed, it needs to be transmitted to the server. That is, after step 204 is executed, the specific processing steps of this information display method further include:

[0076] By contacting the mobile terminal, the first information is transmitted to the mobile terminal, so that the mobile terminal can transmit the first information to the server.

[0077] In practice, after determining the initial information, the user brings the target card into contact with the mobile terminal. The target card then transmits the initial information to the mobile terminal through this contact. Upon receiving the initial information, the mobile terminal sends it to the server based on the target address within that information.

[0078] In an optional embodiment, after determining the first information, the user brings the target card into contact with the mobile terminal. For example, the target card is placed against the information reading surface of the mobile terminal, bringing the NFC chip in the target card close to the information reading surface of the mobile terminal. Then, the target card transmits the first information to the mobile terminal through contact. After receiving the first information, the mobile terminal concatenates the target address in the first information with the address of the mobile terminal to obtain the second information. Then, the mobile terminal transmits the second information to the server.

[0079] Optionally, the address of the mobile terminal can be a MAC address (Media Access Control Address) or an IP address (Internet Protocol Address). This embodiment of the application does not limit the address of the mobile terminal.

[0080] In this embodiment, the transmission of the first information is completed by sending the first information to the mobile terminal and then transmitting the first information to the server through the mobile terminal, which facilitates the subsequent determination of the service result based on the first information.

[0081] In one embodiment, such as Figure 3 As shown, the specific processing steps of step 106 include:

[0082] Step 302: If the service result meets the preset display conditions, display the hidden card number based on the service result.

[0083] The complete card number of the target card includes both the hidden card number and the hint card number. The target card has a hidden card number display area, which is used to display the hidden card number of the target card. The specific content of the displayed condition is that the service result is the first result.

[0084] In practice, the target card has preset display conditions. When the service result is the first result, the target card, based on the encrypted information matched by the service result, energizes the display coil in the hidden card number display area to display the hidden card number.

[0085] Optionally, the number of digits in the hidden card number needs to be less than the number of digits in the target card number. For example, if the target card number is 19 digits, the number of digits in the hidden card number can be 4, 5, or 6 digits. This embodiment of the application does not limit the number of digits in the hidden card number.

[0086] Step 304: Combine the hidden card number and the displayed prompt card number to obtain the complete card number.

[0087] The card number is printed on the target card and is visible to the user.

[0088] In practice, after the hidden card number of the target card is displayed in the hidden card number display area, the target card is then assembled with the hidden card number and the preset display card number to obtain the complete card number of the target card.

[0089] In this embodiment, the hidden card number is displayed under the condition that it is displayed, and then concatenated with the prompt card number of the target card to obtain the complete card number of the target card. This achieves the protection of privacy information and improves the security of information display.

[0090] In one embodiment, such as Figure 4 As shown, the specific processing steps of step 302 include:

[0091] Step 402: If the service result is the first result, determine that the preset display conditions are met.

[0092] In implementation, after receiving the service result, the target card determines whether the service result is the first result. If the service result is the first result, the target card determines that the service result meets the preset display conditions.

[0093] Step 404: Based on the preset encryption algorithm, decrypt the encrypted information matching the service result to obtain the decrypted information.

[0094] In practice, the target card is pre-configured with an encryption algorithm and a private key. Based on the pre-configured encryption algorithm and private key, the target card encrypts the encrypted information matching the service result to obtain the decrypted information.

[0095] Optionally, the encryption algorithm is the SM2 algorithm (an elliptic curve public key cryptography algorithm). This application does not limit the encryption algorithm.

[0096] Step 406: Power on the display coil based on the decryption information to make the display coil show the hidden card number.

[0097] The target card has a hidden card number display area, which contains a display coil.

[0098] In practice, the target card energizes the display coil based on encrypted information, generating a micro-magnetic field. The magnetofluid in the hidden card number display area, based on its physical properties, adheres to the vicinity of the energized display coil, forming a digital display that reveals the hidden card number.

[0099] In this embodiment, when the service result is the first result, the encrypted information matching the first result is decrypted to obtain decrypted information, and the hidden card number is displayed based on the decrypted information, thus completing the display of the hidden card number. Furthermore, transmitting encrypted information improves the security of information transmission.

[0100] In one embodiment, an information display system 100 is provided, wherein the information display system 100 includes:

[0101] The target card 110 is used to obtain a first URL from the mobile terminal 120 and concatenate the first URL with a preset service interface address to obtain a target address; based on the target address and the feature information corresponding to the preset target card, first information is constructed; the first information is used to instruct the server 130 to determine the service result; the server 130 receives the service result transmitted by the server 130, and if the service result meets the preset display conditions, the card number is displayed based on the service result.

[0102] In practice, the specific processing procedure of the target card 110 has been described in detail in the various embodiments of the above information display method, and will not be repeated here in the embodiments of this application.

[0103] Mobile terminal 120 is used to transmit first information and service results.

[0104] In implementation, after the target card 110 determines the first information, it transmits the first information to the mobile terminal 120 via NFC technology. The mobile terminal 120 receives the first information sent by the target card 110. Then, based on the first URL in the first information, the mobile terminal 120 sends the first information to the server 130 corresponding to the first URL. After determining the service result, the server 130 sends the service result to the mobile terminal 120. The mobile terminal 120 receives the service result and transmits it to the target card 110 via NFC technology.

[0105] Server 130 is used to determine the service result based on the first information.

[0106] In implementation, server 130 receives the first information transmitted by the mobile terminal. Then, server 130 determines the service result based on the first information and a preset whitelist database. After obtaining the service result, server 130 sends the service result to mobile terminal 120.

[0107] In this embodiment, the target card constructs first information and transmits it to the server. The server determines the service result based on the first information and feeds the service result back to the target card. This allows the target card to display its card number when the service result meets the display conditions, thus protecting privacy information and improving the security of information display.

[0108] In one embodiment, such as Figure 5 As shown, server 130 is specifically used for:

[0109] Step 502: Receive the first information transmitted by the target card, and determine the service result based on the first URL contained in the first information.

[0110] In implementation, server 130 (hereinafter referred to as server) receives the first information transmitted by the target card. Then, the server parses the first URL and the characteristic information of the target card. Based on the first URL and a preset whitelist database, the server determines the service result.

[0111] Step 504: If the service result is the first result, determine the encrypted information based on the feature information contained in the first information.

[0112] The service results include the first result and the second result.

[0113] In practice, after determining the service result, the server checks whether the service result is the first result. If the service result is the first result, the server encrypts the feature information contained in the first information based on a preset encryption algorithm to obtain the encrypted information matching the first result.

[0114] Step 506: Send the encrypted information and service results to the mobile terminal so that the mobile terminal can transmit the encrypted information and service results to the target card.

[0115] In practice, after receiving the encrypted information and service result, the server sends the service result and the encrypted information matching the service result to the mobile terminal 120 (hereinafter, the number is omitted as "mobile terminal"). After receiving the service result and encrypted information, the mobile terminal transmits the service result and encrypted information to the target card.

[0116] In this embodiment, the server determines the service result based on the first information, and if the service result is the first result, determines the encrypted information. Then, the encrypted information is transmitted to the target card to facilitate the subsequent display of the card number. This achieves the display of the card number only when the display conditions are met, thus protecting privacy information and improving the security of information display.

[0117] In one embodiment, such as Figure 6 As shown, server 130 is specifically used for:

[0118] Step 602: parse the first information to obtain the feature information corresponding to the first URL and the target card.

[0119] In practice, after obtaining the first information, the server parses the first information to obtain the first URL and the feature information corresponding to the target card.

[0120] Step 604: Filter the whitelist URLs that match the first URL from the preset whitelist database.

[0121] In practice, a whitelist database is pre-configured on the server. This whitelist database contains multiple whitelisted addresses. The server filters whitelisted addresses that match the first URL from the pre-configured whitelist database.

[0122] Step 606: If a whitelist URL that matches the first URL exists in the whitelist database, confirm the service result as the first result.

[0123] Among them, the whitelisted addresses are secure addresses.

[0124] In practice, if a whitelisted URL matching the first URL exists in the whitelist database, the server will determine the first result as the service result. Then, the server will determine the first URL as a safe URL.

[0125] Step 608: If there is no whitelisted URL in the whitelist database that matches the first URL, confirm the service result as the second result.

[0126] In practice, if the whitelist database does not contain a whitelist URL that matches the first URL, the server will determine the second result as the service result.

[0127] In this embodiment, the system determines whether the first URL is a whitelisted URL based on the whitelist database to obtain the service result, which facilitates the implementation of different processing logic based on the service result.

[0128] In one embodiment, such as Figure 7 As shown, server 130 is also used for:

[0129] Step 702: If the service result is the second result, confirm that the first URL is a dangerous URL and record the first URL.

[0130] The service results include the first result and the second result.

[0131] During implementation, if the service result is not the first result, the server confirms the service result as the second result. If the service result is the second result, the server confirms the first URL as a dangerous URL. The server records this dangerous URL.

[0132] Step 704: Based on the first URL, construct a warning message and send the warning message to the mobile terminal.

[0133] In practice, after determining that the first URL is a dangerous URL, the server constructs an alarm message based on the first URL and the information that the first URL is a dangerous URL. Then, the server sends the alarm message to the mobile terminal.

[0134] In this embodiment, if the service result is the second result, the first URL is recorded and an alarm message is generated. Then, the alarm message is sent to the mobile terminal, reminding the user that the first URL is an insecure URL, thus improving the security of information display.

[0135] In one embodiment, such as Figure 8 As shown, server 130 is specifically used for:

[0136] Step 802: If the service result is the first result, determine the hidden card number of the target card in the preset card database based on the feature information corresponding to the target card.

[0137] The characteristic information corresponding to the target card is the serial number of the NFC chip contained in the target card. A card database is pre-set in the server. This card database contains the serial number of the NFC chip contained in the target card and the hidden card number of the target card.

[0138] In practice, if the service result is the first result, the server queries the preset card database for the hidden card number of the target card corresponding to the serial number of the NFC chip.

[0139] Step 804: Based on a preset encryption algorithm, encrypt the hidden card number of the target card to obtain encrypted information.

[0140] In practice, the server has a pre-set encryption algorithm and public key. This encryption algorithm is the same as the decryption algorithm in the target card. Based on the pre-set encryption algorithm and public key, the server encrypts the hidden card number of the target card to obtain the encrypted information.

[0141] In this embodiment, if the service result is the first result, the hidden card number is determined and the hidden card number is encrypted to obtain encrypted information, thereby improving the security of transmitting the hidden card number.

[0142] In an optional embodiment, the target card is a specially designed bank card. The first URL is a fake website containing misleading information. This misleading information is used to guide the user to enter the bank card number. The user logs into the fake website via a mobile terminal, causing the mobile terminal to display the fake website. Then, the user brings the specially designed bank card close to the mobile terminal, enabling the specially designed bank card and the mobile terminal's NFC to interact. Through NFC technology, the NFC chip in the specially designed bank card obtains the fake address, thus obtaining the first URL. The NFC chip concatenates the first URL with a preset service interface address to obtain the target address. Then, the NFC chip constructs first information based on the target address and the feature information corresponding to the target card. Then, the NFC chip transmits the first information to the server. Based on the first information, the server determines the service result to be a second result. If the service result is the second result, the server confirms that the first URL is a dangerous URL. Then, the server constructs a warning message based on the first URL and sends the warning message to the mobile terminal to remind the user to avoid entering the specially designed bank card number in the phishing website, thereby protecting the user's resources.

[0143] In one embodiment, the target card integrates an NFC chip. The target card is a specially designed bank card. Figure 9 As shown, a user logs into a mobile website address via a mobile terminal, causing the mobile terminal to display the first website address. A specially designed bank card interacts with the mobile terminal's NFC. The NFC chip in the specially designed bank card obtains the website address, thus obtaining the first website address. The NFC chip concatenates the first website address with a preset service interface address to obtain the target address. Then, the NFC chip constructs first information based on the target address and the feature information corresponding to the target card. The NFC chip then transmits the first information to the server. The server determines the authentication result based on the first information. Then, the server transmits the authentication result to the target card. The target card receives the service result. If the authentication result is unsuccessful, the server determines that the first website address is a fake website address and records the first website address. Then, the server constructs a warning message and sends the warning message to the mobile terminal. If the authentication result is successful, the server determines the encrypted string, thus obtaining encrypted information. Then, the server transmits the encrypted information to the target card. The target card receives the encrypted information. After receiving the encrypted information, the NFC chip in the target card decrypts the encrypted information, thus obtaining decrypted information. Then, based on the decrypted information, the NFC chip energizes the display coil to make the target card display the hidden card number.
