In order to solve the problems in the prior art, the embodiment of the application provides a method, a device, equipment, a storage medium and a product for generating a universal identifier.

The following first describes a method for generating a generic identifier provided by an embodiment of the present application.

Fig. 1 is a flow chart of a method for generating a universal identifier according to an embodiment of the present application. The method is applied to a generation system of the universal identifier, the system comprises a first server, a second server, a user terminal and a proxy server, and the method comprises the following steps S101 to S107.

S101, a second server receives a target request associated with a first user terminal.

S102, the second server responds to the target request, generates a first root identifier and acquires a label vector corresponding to the first user terminal.

S103, the second server generates a first hash value according to the label vector corresponding to the first user terminal.

And S104, the second server sends the first root identifier and the first hash value to the first server.

S105, the first server receives a first root identifier and a first hash value generated by the second server in response to the target request.

S106, the first server determines a universal identifier corresponding to the first user terminal according to the first root identifier and the first hash value.

And S107, the first server sends the universal identifier to the first user terminal.

In the embodiment of the application, first, a first server receives a first root identifier and a first hash value generated by a second server in response to a target request; secondly, the first server determines a universal identifier corresponding to the first user terminal according to a first root identifier and the first hash value, wherein the universal identifier is used for indicating a proxy server to push the target service to the first user terminal and the at least one second user terminal, and a label vector corresponding to each second user terminal is associated with a label vector corresponding to the first user terminal; finally, the universal identifier is sent to the first user terminal; therefore, the universal identifier obtained in the embodiment of the application can determine that a plurality of user terminals have the same tag vector, so that the service can be pushed to the user terminals with the same tag attribute through the universal identifier, and the accuracy of service information pushing is improved.

A specific implementation of each of the above steps is described below.

In some embodiments, in S101, the second server may be an identity server in the system for receiving the target request of the first user terminal, for identifying the identity of each first user terminal. The target request is for the first user terminal to initiate identity recognition of the terminal to the second server.

As an example, the first user terminal may be a communicable handset P, and the second server may be a communications carrier M, and when the user first uses the terminal device or clicks on an application in the terminal device, the handset P sends at least one target request R to the communications carrier M, where the target request R includes information related to the identity of the handset P requested by the communications carrier M.

In some embodiments, in S102, the second server generates a first root identifier according to the target request, where the first root identifier is a unique identifier of the first user terminal; and secondly, obtaining a label vector corresponding to the first user terminal according to the first root mark, wherein the label vector comprises a vector value of at least one target service label associated with target service, and each service label is used for indicating whether a factor influencing whether the user accepts the target service exists or not.

The first root mark may be a character string with a preset length and composed of numbers and letters, and the value range of the tag vector includes a plurality of simple numbers, and each number is used for representing the service possibility represented by the service tag.

As an example, the communication carrier M generates a root identifier AAA666 according to the target request of the mobile phone P, and then passes the root identifier AAA666 obtains label vector LB that cell phone P corresponds to. The label vector LB indicates whether the customer is used to purchase a luxury item in a range of valuesWhere 0 indicates that no luxury is purchased and 1 indicates that there is a luxury purchase.

In some embodiments, in S103, according to the tag vector corresponding to the first user terminal, a hash value of the tag vector is calculated by a hash algorithm, so as to obtain a first hash value.

As an example, the communication carrier M obtains the tag vector LB corresponding to the mobile phone P, and calculates the tag vector LB by using a Message-Digest Algorithm (Message-Digest algorism 5) to obtain a first HASH value 111XXX111111111X1XX11111XX1X11XXX, which is denoted as HASH1, where the Message-Digest Algorithm belongs to one of the HASH algorithms.

In some embodiments, in S104, the second server establishes a data transmission channel with the first server, and then sends the first root identifier and the corresponding first hash value to the first server through the data transmission channel, where the first server is a server dedicated to generating a universal identifier, and may perform an automated process according to the received information, so as to generate the universal identifier.

As an example, the communication carrier M establishes a data transmission channel T with the universal identification platform U, and then the communication carrier M sends the root identification AAA666 and the first HASH value HASH1 in S103 to the universal identification platform U through the data transmission channel T.

In some embodiments, in S105, the first server receives, through the data transmission channel, a first root identifier sent by the second server and a first hash value, where the first root identifier is used as a unique identifier of the first user terminal; in addition, hash algorithm is utilized to carry out hash calculation on a label vector corresponding to the first user terminal, a first hash value is generated, the label vector comprises a vector value of at least one target service label associated with target service, and each service label is used for indicating whether a factor influencing whether the target service is accepted by a user or not.

It should be noted that in the case where a plurality of service tags are associated with a target service, different service tags are used to indicate that factors affecting different services are different.

As an example, the universal identification platform U receives the root identification AAA666 and the first HASH value HASH1 sent by the communication carrier M through the data transmission channel T.

In some embodiments, in S106, the first server may determine, according to the first root identifier and the first Hash value, a universal identifier corresponding to the first user terminal through a Chameleon Hash algorithm (Chameleon Hash).

It should be noted that, when the generating system of the universal identifier is started for the first time, the system parameter initialization process needs to be performed, that is, the initialization process may further include: setting a preset number, and setting a calculator of the hash value of each tag vector as an initial value, wherein the initial value is used for controlling the number of target objects with the same or similar tags corresponding to the universal identifier; and generating system parameters, a public key and a private key by using the chameleon hash algorithm, wherein the system parameters, the public key and the private key are used for providing preset parameters for the chameleon hash algorithm calculation.

As an example, the universal identifier platform U determines, according to the root identifier AAA666 and the first HASH value HASH1, the universal identifier u_id corresponding to the mobile phone P by using a chameleon HASH algorithm.

In one implementation, the universal identifier corresponding to the first user terminal may be determined according to formula (1):

（1）

wherein,,: input of security parameters +.>The structure satisfies the security parameter->Big prime number->And->Selecting multiplication cycle group->Middle order of->Element->Outputting the common parameter->；

: input of common parameters->In the multiplication cycle group->Index +.>Calculate->. Finally, the private key- >Public key->；

: input public key->Message->Random number->Wherein->Outputting the chameleon hash value->Wherein m is any given message;

: input private key->Message->Random number->Wherein->Output ofWherein->For a new message->Is a new random number.

In some embodiments, in S107, the first server sends the universal identifier to the first user terminal, so as to construct an association relationship between the first user terminal and the universal identifier in the system.

It should be noted that the tag vector corresponding to the second user terminal may be the same as or similar to the tag vector corresponding to the first user terminal.

As an example, the universal identifier platform U sends the corresponding universal identifier u_id to the mobile phone P, so that the association relationship between the mobile phone P and the universal identifier u_id is stored in the relationship module of the system.

In some embodiments, before generating the first hash value according to the tag vector corresponding to the first user terminal, the method further includes:

a second server acquires N preset service tags associated with the target service, wherein N is an integer greater than 1;

clustering the N preset service labels to obtain K service label categories, wherein K is an integer smaller than N;

and determining a preset service label meeting a second preset condition as a target service label in each service label class in the K service label classes to obtain at least one target service label associated with target service.

It should be noted that the second preset condition may be that a clustering method such as K-means (K-means clustering algorithm) or euclidean distance is used to calculate at least one target traffic label within a certain range from the central position, so as to determine the traffic label class.

As an example, the method may include the following 5 steps:

counting the number of samples corresponding to each tag, and setting the total number of samples as N, and the tags，/>The value space of (2) is->Then->Sign label->The value is +.>Then for each of the samples All have->. In order to obtain similar label vectors, on one hand, the possible value of each label is reduced; on the other hand, the similarity vectors are classified into one type.

2. Defining a tag distance of two samples asWherein->The indirection function indicates that the tag value is the same as 0 and different from 1. Furthermore, divide by->The reason for (1) is->The larger the specification, the finer the classification, the less weight is given in calculating distance;

4. re-select thisCenter point of class (center tag vector);

5. repeating the steps 3 and 4 to finally obtainAnd similar tag vectors.

The similar label vector can be used as a target service label.

In this embodiment, by acquiring N preset service tags associated with the target service and clustering the N preset service tags, K service tag categories are obtained, and then the preset service tags satisfying the second preset condition are determined as target service tags, so as to obtain at least one target service tag associated with the target service, thereby obtaining more accurate service tag categories.

In some embodiments, the determining, in each of the K traffic label classes, the preset traffic label satisfying the second preset condition as the target traffic label includes:

and determining a preset business label nearest to the center of the business label class as a target business label in each business label class in the K business label classes.

The preset service label is a preset service label category, and the clustering method such as K-means or Euclidean distance is adopted to calculate a preset service label which is closest to the center position and is satisfied as a target service label, so that the service label category is determined.

As an example, there are three preset business labels, namely "willing to purchase a luxury car", "willing to spend a premium purchase", and "willing to purchase a luxury package", respectively, wherein the preset business label, which is "willing to spend a premium purchase", is closest to the center location, thus determining the business label category T as "willing to spend a premium purchase".

In this embodiment, by selecting the preset service label closest to the center of the service label class as the target service label, the method improves accuracy of determining the target service label.

In some embodiments, the receiving a target request associated with a first user terminal includes:

receiving a target request sent by a proxy server and first verification information, wherein the first verification information is generated by the proxy server under the condition of receiving the target request sent by the first user terminal;

the sending the first root identifier and the first hash value to the first server includes:

and sending the first root identification, the first hash value and the first verification information to a first server.

Since the first verification information comprises a bill which can be used for charging, the first verification information can ensure the legitimacy and the security of the target request received by the second server. The proxy server may obtain the target request of the first user terminal, and send the target request and the first authentication information to the second server instead of the first user terminal.

As an example, the communication carrier M receives the target request RQ and the first verification information VY of the proxy server a, processes the information, and then transmits the AAA666, the first HASH value HASH1, and the first verification information VY to the universal identification platform U.

In this embodiment, the proxy server executes the target request associated with the first user terminal, and after completing the request processing, the first root identifier, the first hash value and the first verification information can be more safely and efficiently sent to the first server.

In some embodiments, the determining, according to the first root identifier and the first hash value, a universal identifier corresponding to the first user terminal includes:

under the condition that the first server is determined to have the universal identifier corresponding to the first hash value, acquiring the number of user terminals corresponding to the universal identifier, wherein the universal identifier is generated by the first server in advance according to a second root identifier and a second hash value, the second root identifier is a unique identifier of a target user terminal, the second hash value is generated according to a label vector corresponding to the target user terminal, the second hash value is the same as the first hash value, and the target user terminal is one of the at least second user terminals;

and under the condition that the number of the user terminals corresponding to the universal identification is smaller than the preset number, establishing a corresponding relation between the universal identification and the first user terminal according to the first root identification.

Before determining a certain universal identifier, the number of user terminals corresponding to the universal identifier may be judged, and if the number of user terminals corresponding to the universal identifier is smaller than the preset number, a corresponding relation between the universal identifier and the first user terminal is established according to the first root identifier.

As an example, before determining the universal identifier u_id, searching the universal identifier u_id in the system, if the universal identifier u_id is found to exist, determining the number of user terminals corresponding to the universal identifier u_id, and if the number of user terminals corresponding to the universal identifier u_id is smaller than a preset number, for example, 100, establishing a corresponding relationship between the universal identifier u_id and the mobile phone P according to the first root identifier AAA 666.

As another example, the generic identifier is generated in the following specific manner:

a) If it isThen

i. The universal ID platform is based on hash valuesAnd root ID, use +.A. in chameleon hash>The algorithm generates a general ID;

ii.；

b) If it isThen

i. The universal ID platform is based on hash valuesAnd root ID, use +.A. in chameleon hash>Algorithm generation and pre-sum hash value +.>The same universal ID;

ii.；

c) If it isThen

i. The universal ID platform uses the chameleon according to the hash value and the root IDThe algorithm generates a new general ID;

ii.。

in the method, in the process of the invention,representing by calculating the same hash value +.>To determine the number of user terminals corresponding to a generic identifier, for example>For the preset number, ID (Identity document) is an identity.

In this embodiment, the universal identifier is determined according to the size relationship between the number of user terminals corresponding to the universal identifier and the preset number, so that the controllability of obtaining the universal identifier is improved.

In some embodiments, the method further comprises:

and generating the universal identifier corresponding to the first user terminal according to the first hash value and the first root identifier under the condition that the first server does not have the universal identifier corresponding to the first hash value or the number of the user terminals corresponding to the universal identifier is equal to the preset number.

When a certain universal identifier is determined, the fact that the universal identifier does not exist before is known, or when the number of the user terminals corresponding to the universal identifier is smaller than the preset number, the universal identifier corresponding to the first user terminal can be generated according to the first hash value and the first root identifier.

As an example, when the universal identifier u_id is determined, the universal identifier u_id is not searched in the system, or when the number of user terminals corresponding to the universal identifier u_id is less than a preset number, the universal identifier u_id corresponding to the first user terminal is generated according to the first HASH value HASH1 and the first root identifier AAA 666.

In this embodiment, before determining the universal identifier, it is determined whether the universal identifier exists or if the number of user terminals corresponding to the universal identifier is equal to a preset number, a new universal identifier is generated, so that flexibility of generating the universal identifier is improved.

In some embodiments, the first root identity and the first hash value are generated by the second server upon receiving a target request sent by the proxy server and first authentication information, the first authentication information being generated by the proxy server upon receiving a target request sent by the first user terminal, the method further comprising:

receiving first verification information sent by a proxy server;

the determining the universal identifier corresponding to the first user terminal comprises the following steps:

and under the condition that the first verification information and the second verification information meet a first preset condition, determining a universal identifier corresponding to the first user terminal, wherein the second verification information is information carried by the second server when sending the first root identifier and the first hash value to the first server.

The first preset condition may be that the first verification information is the same as the second verification information or that the difference of the first verification information and the second verification information is within a certain error range.

And the second server generates a first root identifier and the first hash value according to the target request and the first verification information sent by the proxy server, verifies the first verification information and the second verification information sent to the first server by the proxy server, and determines the universal identifier corresponding to the first user terminal when the verification result meets a first preset condition.

As an example, the communication carrier M generates the first root ID AAA666 and the first HASH value HASH1 according to the target request RQ and the first authentication information VY1 sent by the proxy server a, and sends the first authentication information VY1 and the second authentication information VY2 of the generic ID platform U to perform authentication, and determines the generic ID u_id corresponding to the mobile phone P when the authentication result satisfies that the first authentication information is the same as the second authentication information.

In this embodiment, the universal identifier is determined after verification by the first verification information and the second verification information sent to the first server by the proxy server, so that the security and the effectiveness of obtaining the universal identifier are improved.

It should be noted that, because the common identifiers corresponding to the same user terminal in different proxy servers are different, when the service information is pushed by using the common identifier generated by the proxy server mode, the following mode may be adopted:

the first proxy node sends a first universal identifier to a first server;

the first server finds a corresponding first root identifier according to the first universal identifier;

the first server sends a second common identifier corresponding to the first root identifier in a second proxy node to the second proxy node;

And the second proxy node pushes information to the target object corresponding to the second universal identifier.
