[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0026] It should be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0027] The embodiment of the present invention provides a method for checking user information, a terminal device and a storage medium. The method for checking user information can be applied to a terminal device, which can be an electronic device such as a tablet computer, a laptop computer, a desktop computer, a personal digital assistant and a wearable device. The terminal device can be a server or a server cluster.

[0028] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please refer to Figure 1 , Figure 1 A flowchart of a method for verifying user information provided by an embodiment of the present invention.

[0030] like Figure 1 As shown, the method for checking user information is applied to a first terminal, and the method includes steps S101 to S104.

[0031] Step S101: obtain first information corresponding to a first user, and encrypt the first information to obtain a first encryption result.

[0032] Exemplarily, if the first terminal is a bank terminal, the first terminal obtains the first user corresponding to the bank card or credit card, and then obtains the first information corresponding to the first user. The first information includes but is not limited to the credit card number, bank card number, cardholder identity information, etc. corresponding to the first user.

[0033] Exemplarily, the first terminal and the second terminal both use the same public key to encrypt the first information corresponding to the first user and the second information corresponding to the second user, so that when the encryption results are consistent, it indicates that the first user and the second user are the same user, and when the encryption results are inconsistent, it indicates that the first user and the second user are not the same user. Therefore, the first terminal can obtain the first encryption result by encrypting the first information with the second terminal using the same public key.

[0034] In some embodiments, encrypting the first information to obtain a first encryption result includes: obtaining a second public key corresponding to the second terminal; disassembling the first information to obtain first identification information corresponding to the first user; and encrypting the first identification information using the second public key to obtain the first encryption result.

[0035] Exemplarily, the second terminal needs to provide its corresponding second public key. The second public key can usually be provided through a network request, an agreement between terminals, or by a system administrator. Ensure that when obtaining the second public key, a secure method is used to prevent the public key from being tampered with or forged.

[0036] Exemplarily, the first information is disassembled to obtain the required first identification information. The disassembly process includes: determining which parts need to be extracted from the first information as the first identification information. According to a predefined rule or format, the first information is decomposed into multiple components, and the first identification information is extracted therefrom. The first identification information is a unique identifier corresponding to the first user.

[0037] For example, the first terminal will pre-process the credit card customer information that needs to be recommended for card binding, and encrypt the key fields that need to be homomorphically operated (such as the ID number) using the BGV public key, while the non-key fields may be encrypted using symmetric encryption algorithms such as AES. The encrypted data generates a file that is uploaded to the designated data exchange platform through a security protocol and sent to the second terminal. That is, the first terminal disassembles the first information and uses the ID number as the first identification information corresponding to the first user, and other information in the first information except the ID number as non-key fields may be encrypted using symmetric encryption algorithms such as AES.

[0038] Exemplarily, the first identification information is input into an encryption algorithm, and the second public key obtained from the second terminal is used to perform an encryption operation on the disassembled first identification information. After the encryption is completed, the result obtained is the first encryption result.

[0039] Specifically, by obtaining the second public key of the second terminal and using it to encrypt the first identification information, it is possible to ensure that the transmitted identification information is secure in the network. This encryption method ensures that the information will not be accessed or tampered with by unauthorized third parties during transmission. Since the first identification information is encrypted, the user's real identity information will not be directly exposed. This privacy protection measure prevents the leakage of sensitive information and helps protect the user's personal privacy. And using the second public key corresponding to the second terminal to encrypt the first identification information provides support for subsequent user information verification.

[0040] Step S102: Send the first encryption result corresponding to the first user to the second terminal, so that after receiving the first encryption result, the second terminal obtains the second information corresponding to the second user, and encrypts the second information to obtain the second encryption result; matches the first encryption result with the second encryption result to obtain a matching result; determines the target user corresponding to the first user according to the matching result; encrypts the target user and the matching result to obtain a third encryption result, and sends the third encryption result to the first terminal.

[0041] Exemplarily, the first encryption result corresponding to the first user is sent to a second terminal that is communicatively connected to the first terminal. The second terminal is a payment terminal, such as an Alipay platform, a WeChat payment platform, and the like.

[0042] Exemplarily, after the second terminal receives the first encryption result sent by the first terminal, the second terminal obtains the second information corresponding to the second user in its own platform, and then obtains the second identification information in the second information, and thereby uses the public key used by the first terminal to encrypt the first identification information to encrypt the second identification information in the second information to obtain the second encryption result.

[0043] For example, the first identification information is encrypted using the second public key obtained from the second terminal to obtain a first encryption result, and then the second terminal also uses the second public key obtained by the second terminal to encrypt the second identification information in the second information to obtain a second encryption result.

[0044] Exemplarily, after obtaining the second encryption result, the second terminal matches the first encryption result with the second encryption result to obtain a matching result. At this time, it is not necessary to decrypt the first encryption result and the second encryption result, but only to compare the first encryption result and the second encryption result at a preset position to obtain a corresponding matching result.

[0045] Exemplarily, when the matching result is greater than or equal to a preset value, it is determined that the first user corresponding to the first encryption result matches the second user corresponding to the second encryption result, that is, the first user and the second user are the same user, and thus the user in the second user who is represented as the same user as the first user is determined as the target user corresponding to the first user.

[0046] Exemplarily, the second terminal obtains a matching value corresponding to the target user from the matching result, and then encrypts the target user and the matching value corresponding to the target user using an encryption algorithm to obtain a third encryption result, and sends the third encryption result to the first terminal.

[0047] For example, the second terminal uses the first public key corresponding to the first terminal to encrypt the target user and the matching value corresponding to the target user to obtain a third encryption result.

[0048] Step S103: Receive the third encryption result corresponding to the second terminal, and decrypt the third encryption result to obtain the target user and the matching result.

[0049] Exemplarily, the third encryption result corresponding to the second terminal is received, and the third encryption result is decrypted according to a decryption algorithm corresponding to the encryption algorithm used when the third encryption result is obtained in the second terminal to obtain the target user and the matching result.

[0050] In some implementations, decrypting the third encryption result to obtain the target user and the matching result includes: obtaining a first private key corresponding to the first terminal; and decrypting the third encryption result according to the first private key to obtain the target user and the matching result.

[0051] Exemplarily, the second terminal uses the first public key corresponding to the first terminal to encrypt the target user and the matching value corresponding to the target user to obtain a third encryption result. After the first terminal receives the third encryption result corresponding to the second terminal, it uses the first private key corresponding to the first terminal to decrypt the third encryption result to obtain the corresponding target user and matching result.

[0052] Specifically, the third encryption result is decrypted using the first private key corresponding to the first terminal, ensuring that only the first terminal holding the private key can decrypt and access the information during the entire decryption process, which can effectively protect the user's privacy and sensitive data and avoid information leakage, thereby effectively protecting data security and user privacy, while providing accurate user identity information and matching results. This practice helps support the reliability of the system, the decision-making process, and ensures compliance with data protection and privacy protection requirements.

[0053] Step S104: Determine the information verification result corresponding to the first user according to the target user and the matching result.

[0054] For example, the usage rate of the first user corresponding to the first terminal in the second terminal is determined according to the target user, and the reliability of the usage rate can be determined according to the matching result. Thus, the information checking result corresponding to the first user is determined according to the target user and the matching result.

[0055] For example, the number of first users corresponding to the target user when the matching result is more than 90%, and the number of second users corresponding to the target user when the matching result is less than or equal to 90% but greater than 80% are counted. Thus, according to the above screening conditions, the number of first users and the number of second users are calculated, and then the degree of binding of the user's bank card in the first terminal by the second terminal is analyzed according to the above numbers, so as to obtain the success rate of binding the bank card or credit card corresponding to the first terminal in the second terminal.

[0056] For example, it is impossible to determine with 100% certainty that the target user is the same in the first terminal and the second terminal, and then the reliability of the same target user in the first terminal and the second terminal is determined by the matching result, so that the target user is screened according to the matching result, thereby obtaining the information verification result corresponding to the first user. Therefore, while protecting user privacy, the present application can also analyze whether the first user in the first terminal and the second user in the second terminal have the same target user.

[0057] In some embodiments, after obtaining the information verification result, the method further includes: determining the number of users corresponding to when the first user and the second user are consistent based on the information verification result; and performing information recommendation based on the number of users to determine a user strategy corresponding to the target user.

[0058] Exemplarily, the information verification result includes the number of users corresponding to different matching results, and then the usage rate corresponding to the first terminal when used in the second terminal is determined according to the number of users corresponding to the consistency between the first user and the second user. For example, the number of users is ratio-calculated with the number corresponding to the first user of the first terminal to obtain the usage rate corresponding to the first terminal when used in the second terminal.

[0059] Exemplarily, rules or algorithms for information recommendation are defined, and these rules may formulate user strategies based on factors such as usage rate and number of users.

[0060] For example, when the usage rate is high, the recommended strategy should encourage continued binding. For example, if a user frequently uses certain functions or services, this indicates that the user has a high dependence on the second terminal. It is recommended to recommend strategies for further binding with the second terminal, such as providing additional functions, service discounts, or enhanced permissions to consolidate the existing binding relationship. When the user's usage rate is low, the recommended strategy should help the user strengthen the willingness to bind with the second terminal. For example, low usage may indicate that the user is dissatisfied with the current binding status or fails to fully utilize the second terminal. It is recommended to recommend strategies that can attract user interest, such as providing trial periods, personalized service recommendations, or binding discounts, to increase users' willingness to bind and usage frequency. When the number of users is large, the recommended strategy should focus on maintaining and optimizing the experience of existing users. For example, a large number of users may require systematic improvements or additional support. It is recommended to develop strategies that can improve user satisfaction and loyalty, such as launching group activities, enhancing user support services, or conducting regular feedback surveys. When the number of users is small, the recommended strategy should focus on attracting more users or improving users' usage experience to increase the user base. It is recommended to adopt strategies to attract new users, such as launching referral rewards, user invitation mechanisms, or customized services for small user groups.

[0061] Specifically, by determining the consistency between the first user and the second user and the corresponding number of users according to the information verification results, the real identity and matching relationship of the users can be accurately identified. This improves the accuracy of data processing and reduces the possibility of mismatching. By determining the user consistency and the corresponding number of users according to the information verification results, and making information recommendations based on this, the accuracy of user matching can be effectively improved, information recommendations can be optimized, user experience can be enhanced, decision support can be improved, user stickiness can be enhanced, the flexibility and adaptability of strategies can be improved, and resource allocation can be optimized. These beneficial effects ultimately help improve the overall performance of the system and user satisfaction.

[0062] Please refer to Figure 2 , Figure 2 A flowchart of another method for verifying user information provided by an embodiment of the present invention.

[0063] like Figure 2 As shown, the method for checking user information is applied to the second terminal, and the method includes steps S201 to 205.

[0064] Step S201: Obtain a first encryption result corresponding to a first user sent by a first terminal.

[0065] Exemplarily, the second terminal is communicatively connected to the first terminal. When the first terminal encrypts the first identification information corresponding to the first user to obtain a first encryption result, the first terminal sends the first encryption result to the second terminal, so that the second terminal receives the first encryption result corresponding to the first identification information sent by the first terminal.

[0066] Step S202: Obtain second information corresponding to the second user, and encrypt the second information to obtain a second encryption result.

[0067] Exemplarily, the second terminal obtains the second information corresponding to the second user in its own platform, and then obtains the second identification information in the second information, and then uses the public key used by the first terminal to encrypt the first identification information to encrypt the second identification information in the second information to obtain the second encryption result.

[0068] For example, the first identification information is encrypted using the first public key obtained from the first terminal to obtain a first encryption result, and then the second terminal also uses the first public key obtained by the first terminal to encrypt the second identification information in the second information to obtain a second encryption result.

[0069] In some embodiments, encrypting the second information to obtain a second encryption result includes: obtaining a second public key corresponding to the second terminal; disassembling the second information to obtain second identification information corresponding to the second user; and encrypting the second identification information using the second public key to obtain the second encryption result.

[0070] Exemplarily, the first identification information is encrypted using the second public key obtained from the second terminal to obtain a first encryption result. Then, the second terminal decrypts the second information to obtain the second identification information corresponding to the second user, and then encrypts the second identification information using the second public key to obtain a second encryption result.

[0071] Specifically, the step of encrypting it with the second public key can not only significantly improve data security, enhance identity authentication, improve data integrity, protect privacy, support secure communications, optimize system trust, meet compliance requirements, and enhance the system's defense capabilities, but also obtain the first encryption result and the second encryption result through the same encryption method, which can provide good support for subsequent accurate information query results.

[0072] Step S203: performing information matching on the first encryption result and the second encryption result to obtain a matching result.

[0073] Exemplarily, after obtaining the second encryption result, the second terminal matches the first encryption result with the second encryption result to obtain a matching result. At this time, it is not necessary to decrypt the first encryption result and the second encryption result, but only to compare the first encryption result and the second encryption result at a preset position to obtain a corresponding matching result.

[0074] In one embodiment, the first encryption result and the second encryption result are matched to obtain a matching result. Specifically, referring to Figure 3 , step S203 includes: sub-step S2031 to sub-step S2033.

[0075] Sub-step S2031, setting a verification function, and comparing the first encryption result and the second encryption result bit by bit according to the verification function to obtain a comparison result.

[0076] Exemplarily, the second terminal creates an empty matching set, traverses the second encrypted result it has encrypted, and performs the following operations: searching for a matching hash value prefix in the first encrypted result provided by the first terminal. The second terminal calculates a check function (such as a bitwise XOR sum) between the encrypted hash values ​​corresponding to the first encrypted result and the second decrypted result to obtain a comparison result of the first encrypted result and the second encrypted result under the check function.

[0077] Sub-step S2032: When the comparison result meets a preset condition, the first user corresponding to the first encryption result is added to a matching set.

[0078] Exemplarily, the preset condition is a corresponding value at a preset position or satisfies a preset value. When the comparison result satisfies the preset condition, it is inferred whether there is a possibility of a match between the first user corresponding to the first encryption result and the second user corresponding to the second encryption result. Thus, when the comparison result satisfies the preset condition, the first user corresponding to the first encryption result is added to the matching set. When the comparison result does not satisfy the preset condition, the first user corresponding to the first encryption result cannot be added to the matching set.

[0079] Sub-step S2033: determining the matching result according to the matching set and the comparison result.

[0080] Exemplarily, a matching value corresponding to each user in the matching set is obtained from the comparison result, and then each user in the matching set and the matching value corresponding to each user are determined as the matching result.

[0081] Specifically, by setting a verification function and comparing the first encryption result and the second encryption result bit by bit, it is possible to accurately verify whether the two encryption results are consistent. This meticulous comparison method helps to ensure the matching degree of the data after encryption, thereby verifying the accuracy and consistency of the data. By adding the first user corresponding to the first encryption result that meets the preset conditions to the matching set, it is possible to systematically manage and record those users who have successfully matched. This helps to improve the accuracy of the matching and ensures that only users who are considered to be matched under strict conditions enter the set. This provides support for obtaining accurate information verification results in the future.

[0082] Step S204: Determine a target user corresponding to the first user according to the matching result.

[0083] Exemplarily, when the comparison result in the matching result is greater than a preset value, the user corresponding to the comparison result is determined as the target user.

[0084] Step S205: encrypt the target user and the matching result to obtain a third encryption result, and send the third encryption result to the first terminal, so that the first terminal determines the information verification result corresponding to the first user according to the third encryption result.

[0085] Exemplarily, the second terminal uses a set encryption algorithm to encrypt the target user and the matching value corresponding to the target user in the matching result to obtain a third encryption result, and then sends the third encryption result to the first terminal, so that the first terminal determines the information verification result corresponding to the first user based on the third encryption result.

[0086] In some implementations, encrypting the target user and the matching result to obtain a third encrypted result includes: obtaining a first public key corresponding to the first terminal; and encrypting the target user and the matching result according to the first public key to obtain the third encrypted result.

[0087] Exemplarily, the second terminal obtains the first public key corresponding to the first terminal, and then uses the first public key to encrypt the target user and the matching result to obtain a third encryption result, so that after obtaining the third encryption result, the first terminal uses the first private key corresponding to the first terminal to decrypt the third encryption result to obtain the target user and the matching result.

[0088] Specifically, by obtaining the first public key corresponding to the first terminal and encrypting the target user and the matching result, the security of these data during transmission can be ensured. Even if the data is intercepted, it cannot be decrypted without the corresponding private key, thereby effectively preventing data leakage and illegal access.

[0089] Please refer to Figure 4 , Figure 4A schematic diagram of a scenario for implementing the method for checking user information provided in this embodiment, such as Figure 4 As shown, the first terminal obtains the first information corresponding to the first user, and obtains the second public key corresponding to the second terminal; the first information is disassembled to obtain the first identification information corresponding to the first user; the first identification information is encrypted using the second public key to obtain the first encryption result, and the first encryption result corresponding to the first user is sent to the second terminal. After receiving the first encryption result, the second terminal obtains the second information corresponding to the second user, disassembles the second information to obtain the second identification information corresponding to the second user; the second identification information is encrypted using the second public key to obtain the second encryption result; the second terminal matches the first encryption result with the second encryption result to obtain the matching result; the target user corresponding to the first user is determined according to the matching result; the second terminal obtains the first public key corresponding to the first terminal; the target user and the matching result are encrypted according to the first public key to obtain the third encryption result, and the third encryption result is sent to the first terminal; the first terminal receives the third encryption result corresponding to the second terminal, and decrypts the third encryption result to obtain the target user and the matching result; the first terminal finally determines the information verification result corresponding to the first user according to the target user and the matching result. This encryption matching mechanism solves the contradiction between privacy protection and effective use of data in traditional technologies. In many existing systems, privacy protection often leads to inefficient information verification, but this method overcomes this problem through innovative encryption and matching processes, improving the efficiency and accuracy of information verification. Overall, this method optimizes the user identity verification process on the basis of ensuring information security and privacy protection, and effectively improves the performance and reliability of the system.
