Invention embodiment

Embodiments of the present invention

It should be noted that the information recommendation method of the exemplary embodiment of the present disclosure may be implemented by a server, that is, the server may execute each step of the information recommendation method. In this case, the information recommendation device of the exemplary embodiment of the present disclosure may be included in the server.

The server can be a server in the country of the target user and used for identity verification. The server may be a node on the blockchain, or the server may establish a communication connection with a node of the blockchain. Wherein, the server may also be constructed in the manner of a server cluster, and the exemplary embodiments of the present disclosure do not impose special restrictions on the construction form, geographic location, and the like of the server.

In addition, the verification system described below is an identity verification system for a target user's cross-border destination. In an exemplary embodiment of the present disclosure, when the user is not a citizen of the cross-border destination, the verification system does not perform the actual identity verification process Instead, it receives the user’s identity verification request and sends the request to the above-mentioned server through the blockchain so that the above-mentioned server can verify the user’s identity. For ease of description, the above server can also be marked as the target system.

Fig. 1 schematically shows a flowchart of an information recommendation method according to an exemplary embodiment of the present disclosure. Referring to FIG. 1, the information recommendation method may include the following steps:

S12. Receive an identity verification request for the target user sent by the verification system through the blockchain; wherein the verification system is an identity verification system for the target user's cross-border destination.

When the target user enters the country, it is usually necessary to verify the user's identity. The verification system is a cross-border destination identity verification system for the target user. When the target user enters the country, the verification system can obtain the entry information of the target user. The entry information can be obtained based on the entry card filled in by the target user. In addition, the entry information can also be obtained from the visa Obtained by the issuing unit, which is not specifically limited in this exemplary embodiment.

Specifically, the entry information of the target user may include, but is not limited to, the target user's name, entry time, entry purpose, stay time, electronic IDentity (eID), nationality, digital certificate, digital signature, etc.

First, the verification system can determine whether the target user is a citizen of a cross-border destination by nationality, and if so, the verification system further verifies the identity of the target user. It is easy to understand that the exemplary embodiments of the present disclosure are mainly aimed at situations where the target user is not a citizen of a cross-border destination.

If it is determined that the target user is not a citizen of a cross-border destination, the verification system can use the entry information to generate an identity verification request. Specifically, the verification system can integrate the entry information of the target user in combination with its own identification, timestamp and other information to generate an identity verification request uniquely corresponding to the target user.

Next, taking the verification system as a node on the blockchain as an example, the verification system can package the identity verification request into a block and upload it to the blockchain network. However, it is easy to understand that the verification system can also be a system that communicates with a node on the blockchain. The verification system sends the identity verification request of the target user to the blockchain node connected to it, and the blockchain node Package and upload to the blockchain network.

According to an embodiment of the present disclosure, the server may be a node on the blockchain, and thereby, the identity verification request of the target user may be obtained; according to other embodiments of the present disclosure, the server may communicate with a blockchain node The connected server, in this case, the server can obtain the identity verification request of the target user from the blockchain node.

It is easy for those skilled in the art to understand that the sending and obtaining of various transactions on the blockchain depends on encryption and decryption algorithms, and this disclosure does not impose special restrictions on this.

S14. Extract multiple pieces of to-be-verified information from the identity verification request, and verify the identity of the target user based on the multiple pieces of to-be-verified information.

In the exemplary embodiment of the present disclosure, the multiple pieces of information to be verified include, but are not limited to, the electronic identity, digital certificate, and digital signature of the target user.

According to some embodiments of the present disclosure, first, the server can determine the digital certificate corresponding to the electronic identity of the target user according to the mapping relationship between the electronic identity and the digital certificate, where the mapping relationship can be pre-configured; next, if the target The digital certificate corresponding to the user's electronic identity is consistent with the digital certificate in the identity verification request, then the digital signature in the identity verification request is verified, and the identity verification of the target user is determined based on the verification result of the digital signature.

Specifically, it is easy for those skilled in the art to understand that for the process of verifying digital signatures, first, the server can decrypt the digital signature with the public key of the verification system, derive the digest, and use the digest as the first digest; The original text of the identity verification request is hashed to obtain the second digest; then, the first digest and the second digest are compared to determine whether the two are the same. If they are the same, the digital signature verification is successful.

In addition, before comparing and verifying the digital certificate, the server can determine whether the digital certificate is issued by the country to which the server belongs. If not, the server can feed back the verification failure information to the verification system; if so, the server can perform the digital certificate , The verification process of the digital signature.

According to other embodiments of the present disclosure, in order to further accurately verify the identity of the target user, the present disclosure also provides a solution based on face comparison. Specifically, in the case where the digital signature verification in the above example is successful, first, the server can obtain the face image taken for the target user from the verification system as the first image; in addition, the server can determine the identity corresponding to the target user’s electronic identity. The face image, as the second image, specifically, the face image corresponding to the electronic identity tag can be determined, for example, from the visa or ID card; next, the first image can be compared with the second image, and based on the comparison The result determines whether the authentication of the target user is successful. Wherein, if the first image and the second image correspond to the same user, it can be determined that the identity verification of the target user is successful.

For the comparison process between the first image and the second image, for example, a trained machine learning model can be used to extract facial features from the first image and the second image respectively, and the similarity between the features can be calculated. If the similarity is greater than If the similarity threshold is preset, it can be considered that the first image and the second image correspond to the same user.

It should be understood that if any one of the above-mentioned information to be verified fails to be verified, the server may send the verification failure information to the verification system. After the verification system receives the verification failure message, it can send out an alarm message to remind the security personnel that the target user needs to be further identified.

S16. If the identity verification of the target user is successful, determine recommended items related to the cross-border destination.

In the exemplary embodiment of the present disclosure, the recommended item may represent the type of recommended information, that is, each recommended item may correspond to one type of recommended information. Specifically, the recommended items may include, but are not limited to, maps of cross-border destinations, catering information, current exchange rates, local friendliness, traffic information, insurance that meets local characteristics, and so on.

According to some embodiments of the present disclosure, if the identity verification of the target user is successful, the server may obtain the entry purpose information of the target user from the verification system. Specifically, the verification system may determine the entry and exit purpose information from the entry card filled out by the target user, and send it to the server.

Next, the recommended items related to the cross-border destination can be determined according to the destination information of the target user. Specifically, the mapping relationship between the entry purpose and the recommended items can be constructed in advance. For example, if the destination of the target user is tourism, it can be determined that the recommended items related to tourism are maps, local dining information, traffic information, and so on. For another example, if the purpose of the target user's entry is to study abroad, the recommended items may include insurance that meets local characteristics, contact information of the fellow villagers' association, and so on.

According to other embodiments of the present disclosure, if the identity verification of the target user is successful, the server can obtain the contact information of the target user. Specifically, the electronic identity and contact information of the target user can be pre-bound and stored, and the server can store according to the target user The electronic identity of the target user determines the contact information of the target user.

Next, the server can send the recommended items to be selected to the client terminal of the target user according to the contact information, so that the user can make a selection. After the target user selects, the result of the selection of the recommended item can be sent to the server through the user terminal. Accordingly, the server uses the recommended item actively selected by the target user as the recommended item related to the cross-border destination described in step S16.

According to other embodiments of the present disclosure, first, the server can obtain the entry purpose information of the historical user and the recommended items selected by the historical user. For example, the historical user A determines the recommended item 1 by checking, and the historical user B checks The selection method determines recommended item 2 and recommended item 3, and so on.

Next, the server can determine the relationship between the entry purpose information and the recommended items based on the entry purpose information of the historical user and the recommended items selected by the historical user. For example, for the case where the recommended item is a map, determine the number of times the map has been ticked among users whose inbound purpose is travel, and the total number of these historical users, and based on these two values, determine that the inbound purpose is tourism and the recommended item is a map For example, the number of users whose entry purpose is to travel is n. If m users out of these n users check the map as a recommendation item, the degree of relevance between travel and the map is m/n, in this case Next, an association threshold (for example, 70%) can be pre-configured, and if m/n is greater than the association threshold, it is determined that the recommended item corresponding to the user with the purpose of traveling includes a map.

Subsequently, in practical applications, the association relationship can be used to determine the recommended item corresponding to the destination information of the target user.

In addition, different weights can be configured for each recommended item in advance, and the above-mentioned degree of association can be determined by combining the weights. For example, for the case where the recommended item is a map, the weight of the map can be configured as w, and the degree of association between tourism and the map can be determined as w* m/n. In this case, if w*m/n is greater than the associated threshold, it is determined that the recommended item corresponding to the user whose purpose is to travel includes a map.

It should be understood that, in view of the real-time changes in historical user data, this method of automatically determining recommended items based on historical user data is a process in which the relationship between entry purposes and recommended items dynamically changes. In addition, this embodiment can also provide a solution for user feedback. Specifically, if the server determines that the recommended item is a map, it sends the map to the user, and the user does not want the map as the recommended information, it can feed back to the server through the user terminal. The user's electronic identity can be recorded, and the map will not be used as a recommendation item for the user in subsequent cross-border information recommendations.

S18. Use the real-time information corresponding to the recommended item as recommended information and send it to the target user.

According to some embodiments of the present disclosure, after the recommended item is determined in step S16, the server may obtain real-time information corresponding to the recommended item from the third-party application system. Among them, the server has established a mutual trust relationship with third-party application systems in advance to obtain real-time information. Specifically, the third-party application system may be a system related to recommended items.

Taking the recommendation item as catering information as an example, the third-party application system may be a food evaluation platform, a forum, etc. For example, the server can obtain evaluation information on cross-border destination catering from users of the same nationality as the target user from the food evaluation platform, and can also rank local catering based on the evaluation information to determine real-time information on the catering rankings. Subsequently, the server can use the real-time information as recommendation information and send it to the target user.

Taking the recommended item as the current exchange rate as an example, the third-party application system can be a system that discloses real-time exchange rate information. The server can obtain local real-time exchange rate information from the system, and use the real-time exchange rate information as recommended information to send to the target user.

According to other embodiments of the present disclosure, the server may predict the consumption ability of the target user, and determine the real-time information corresponding to the recommended item that matches the consumption ability as recommended information, and send it to the target user.

Specifically, the spending power in the recent period (for example, half a year) can be predicted. For example, the industry of the target user can be determined from the entry information, and the average salary level of the industry can be determined. It can be considered that the average salary level of the industry is equal to that of the industry. Consumption power is proportional. Specifically, the sample data can be used to determine the correlation between the average salary level of the industry and the spending power in advance, and the spending power of the target user can be determined based on this correlation.

In addition, the consumption power can be divided into several levels, each level corresponding to different recommended content.

Still taking the recommendation item as catering information as an example, if the target user's spending power level is high, the target user is recommended to the target user with higher price and better quality restaurant information.

Taking the recommendation item of insurance as an example, if the target user has a higher level of spending power, insurance products with a wide range of coverage can be used as recommended information and sent to the target user.

According to other embodiments of the present disclosure, for the process of determining the recommended information, first, the server can determine whether the target user has a companion.

In one embodiment, the server can establish a mutual trust relationship with a third-party insurance platform (or education and other platforms). As a result, the server can obtain users who are closely related to the target user from the third-party insurance platform. If the persons entering at the same time include these users , Then it can be determined that the target user has a companion.

In another embodiment, the server can establish a mutual trust relationship with the airline, and thus, it can be determined from the airline's ticket sales record whether the target user has a companion. Specifically, in the historical ticket sales records related to the target user, if the user A is recorded multiple times, it can be determined that the user A is a companion of the target user. For example, within three years, the target user has taken 8 flights in total, and the same user A exists in 6 of them, and then the user A is determined to be a companion of the target user.

In another embodiment, the server may extract from the entry-exit record the situation of the target user's previous cross-border counterparts. For example, if the target user has left the country three times in two years, and the same user B is recorded in the exit records of these three times, then user B can be determined as a companion of the target user.

Next, when it is determined that the target user has peers, the real-time team information corresponding to the recommended item can be determined, and the real-time team information can be recommended to the target user. Wherein, the team information mentioned here may include, for example, team insurance products, team play plans, and the like.

The entire process of the information recommendation method of the present disclosure will be described below with reference to FIG. 2.

In step S202, when the target user arrives at the cross-border destination, the verification system of the cross-border destination can generate an identity verification request for the target user when it determines that the target user is not a citizen of the cross-border destination, and send the request to Packed into blocks.

In step S204, the verification system uploads the generated block to the blockchain network, so that the target system (that is, the aforementioned server) for identity verification in the country where the target user belongs can obtain the identity verification request.

In step S206, the target system verifies the user's identity based on the multiple pieces of to-be-verified information in the identity verification request. Specifically, the target user's electronic identity, digital certificate, and digital signature can be used to verify the identity.

In step S208, if the identity verification is successful, the target system may feed back the result of the successful verification to the verification system. In addition, if the identity verification fails in step S206, the target system can feed back information that the identity verification has failed to the verification system to remind the security personnel of the cross-border destination that the target user is a suspicious person.

In step S210, if the identity verification is successful, the target system may determine recommended items related to the cross-border destination.

In step S212, the target system may obtain real-time information corresponding to the recommended item from the third-party application system as the recommended information. It should be understood that the third-party application system mentioned here may include multiple systems that can provide real-time information related to cross-border destinations.

In step S214, the target system may obtain the contact information of the target user, and send the recommendation information to the user terminal. For example, the contact method can be a mobile phone number, and the target system can send the recommendation information to the user's mobile phone by SMS; or the contact method can be an email, and the target system can automatically edit the content of the email containing the recommendation information and send the email to the user Cell phone.
