Method and device for processing authentication request message in social network

The present application belongs to the field of Internet technologies, and in particular, to a method and apparatus for processing an authentication request message in a social network.

In the existing Internet, the social network formed by online informants is no longer just a relationship between a single user and a single user, but a one-to-many and many-to-many relationship. The social network includes online users and their relational networks, such as instant messaging service (IM) systems and WEB2.0-based Internet SNS (social network service) communities. For example, IM tools, different users. IM information is communicated through the IM client. Before communicating with each other, the general IM software requires users to establish a certain two-way social network relationship before communication begins to accelerate the positioning of communication objects and prevent unnecessary Users send useless information and unnecessary harassment. In the current IM software technology, if user A initiates communication to user B who is not in his social relationship list, that is, user A requests to establish a certain social relationship with user B, user A generally needs to send an authentication request to user B. Message, the application becomes a user with a certain social relationship with user B. Only after User B has verified the request of A, can User A find B in his social relationship list and initiate communication and chat.

When user A and user B become users with certain socialized relationship, user B can only know the identity information or other information of user A through the authentication request message manually input by user A to determine whether to establish a social relationship with user A. It can be seen that the authentication request message in the prior art completely relies on the manual input of the user A. The system cannot automatically obtain the identity information of the user A and the social relationship information between the user A and the user B, so that the user A and B are reduced on the one hand. The efficiency of the social relationship, on the other hand, can not provide enough parameter information for User B to verify User A's authentication request message.

In order to solve the problem that the user authentication in the prior art is less efficient and less dependent on the request for establishing the social relationship, the embodiment of the present application provides a method for processing an authentication request message in a social network, including: After obtaining the authentication request message that the first user end establishes a social relationship with the second user end, the network server obtains the social attribute information common to the first user end and the second user end, and socializes The attribute information is used to indicate the attribute of the social network user in the social network; the social network server forwards the authentication request message to the second user, and sends the acquired social attribute information, the socialization The attribute information is used by the second user end to perform authentication processing on the authentication request message.

At the same time, the embodiment of the present application further provides an apparatus for processing an authentication request message in a social network, including: an obtaining module, configured to learn that the first user end sends a authentication to establish a socialized relationship with the second user end to the second user end. After requesting the message, the social attribute information shared by the first user end and the second user end is obtained, and the social attribute information is used to indicate the attribute of the social network user in the social network; the sending module is used to: Forwarding the authentication request message to the second user end, and sending the obtained socialized attribute information, where the socialized attribute information is used by the second user end to perform authentication processing on the authentication request message.

As can be seen from the specific implementation provided by the foregoing application, the social network server automatically obtains the first information after the first user terminal sends an authentication request message to the second user end to establish a social relationship with the second user end. The social attribute information shared by the client and the second user is displayed to the second client. The parameter information on which the second user end verifies the authentication request message of the first user end is added, and the efficiency of establishing a social network relationship between the first user end and the second user end is improved.

detailed description

The first embodiment provided by the present application is a method for processing an authentication request message in a social network, which is implemented in a network topology as shown in FIG. 1, the network includes: a social network server, and a plurality of The user terminal, the method flow is as shown in FIG. 2, and includes: Step 101: The UE identified as A sends a socialized relationship with the client identified as B through the social network server to the client identified by B. Request message.

Step 102: The social network server obtains the identification information A and the identification information B after learning that the request sent by the user end of the identifier A is the authentication request message for establishing a social relationship with the user end of the B.

Step 103: The social network server determines, according to the identification information A and the identification information B, that the keywords storing the index records are (AB) or "AB" and "(AB)", etc. from a plurality of servers or one server. The server of the inverted index file is server 1.

Step 104: From the server 1, the social network server extracts the index record with the keyword (AB), and extracts the social attribute information common to the client identified as A and the user identified as B. Or extract the relationship chain information between the client identified as A and the client identified as B.

Step 105: The social network server sends the extracted common social attribute information to the client identified as B, or sends the extracted common relationship chain information.

Step 106: The client identified as B displays the received socialized attribute information or the extracted common relationship chain information of the user end with the identifier A and the user ID identified as B.

In step 101, the client identified as B stores one or more socialized relationship lists locally. For example, the socialized relationship list 1 has five client identifiers and corresponding socialized relationship categories, indicating that the identifier is C. The socialized relationship category of the user end of D, E, F, and G and the user end marked as B is 1. There are three user-side identifiers and corresponding socialized relationship categories in the social relationship list 2, and the socialized relationship category is 2. Table 1 is used to store the client identifier of the socialization relationship category 1, and Table 2 stores the client identifier of the socialization relationship category 2.

Table 1

Table 2

The client identified as A sends the authentication request message of the join table 1 to the client identified by B through the social network server, and the authentication request message sent by the client A carries the identification information A of the user A.

The social network server can be installed on any server in the social network, such as server 1, server 2 or server 3 in a social network.

In step 102, after receiving the authentication request message sent by the client identified by A, the social network server analyzes the authentication request message, and extracts the identification information A and the identification information B from the authentication request message. Further, the social network server determines that the client having the direct social network relationship with the client A and the client B has the client C and the client D, and the social network server receives the authentication sent by the client A. After requesting the message, analyzing the authentication request message, extracting the identification information B of the receiving client from the authentication request message, and storing the same table 1' as the content of Table 1 in the database of the social network server, according to the storage In the same table 1' of the social network server as in Table 1, it is determined that the client having a direct social network relationship with the client B has the client C and the client D. In this step, the social network server can obtain a direct social network relationship with the client B through the query, and the client includes the C and the client D, and the social network server receives the client A. After the authentication request message is sent, the authentication request message is analyzed, the identification information A of the sending client is extracted from the authentication request message, and a direct social network relationship with the client A is determined according to a method similar to that of the client B. The client side also includes the client terminal C and the client terminal D. As a preferred solution, the client terminal C and the client terminal D have a direct social network relationship with the client terminal A, and the client terminal D and the client terminal C and the client terminal B. There are also direct social networking relationships. Of course, it can also be the client D and the client C, and has a direct social network relationship with the client B. At the same time, the client D and the client C have a social network relationship with the client A, but it is not a direct social network. Road relationship. The user C is selected from the user C and the user D according to a predetermined rule, and the identification information C of the user C is obtained. The predetermined rule may be that the social network server automatically calculates the social network relationship chain with the highest degree of familiarity between the client A and the client B, such as the client A-> client C-> client B The familiarity is Y1+X1; the familiarity of another social network relationship chain client A->user D>user B is: Y2+X2. If Y1+X1>Y2+X2, then from the client D. The client C is selected from the client C, and the identification information C of the client C is obtained. Otherwise, the user terminal D is selected. In this embodiment, the user terminal C is selected as a preferred solution. In this step, the user terminal D or the client terminal C is selected by the familiarity. Of course, one of the user terminal D and the client terminal C may be selected according to the familiarity. Or the social network server selects one of the user terminal D and the client terminal C according to the number of the client identifiers in the social network relationship list of the client D and the social network relationship list of the client C, for example, The number of user identifiers in the social network relationship list of the client C is 10, and the number of user identifiers in the social network relationship list of the client D is 100, due to the social network relationship of the client C. The number of client IDs in the list is less than that of the client D, indicating that the client C may choose its own social network relationship object more carefully. Therefore, the user C is selected, and the user B may also occupy the client C. The proportion of the client in the social network relationship list is 1/10, and the ratio of the client in the social network relationship list of the client D is 1/100, and the client C is selected. Of course, by setting a threshold, such as 1/20, the ratio of the client in the social network relationship list of the client B to the client C is 1/10, which is greater than the threshold 1/20, and the client B occupies the client. The proportion of the client in the social network relationship list of D is 1/100, which is less than the threshold 1/20. Therefore, the client C is selected.

Or the social network server automatically selects the client C and the client D, and has the highest familiarity with the client B: if X1>X2, the social network server selects the client C; otherwise, the user D is selected. . In this embodiment, the user terminal C is selected as a preferred solution.

Of course, in addition to adopting the predetermined rule to select the client C, the social network server can send the identifiers D and C of the client D and the client C to the client A, and if the client A selects C, the society The network server selects the client C according to the selection of the client A. Otherwise, if the client A selects D, the social network server selects the client D according to the selection of the client A.

Familiarity can be obtained by the following method. It is assumed that the time (for example, 30 days) between two client terminals is N, and the familiarity value corresponding to unit time (such as 1 day) is M, then familiarity. The time weight value is N×M; and it is assumed that the familiarity value corresponding to the information interaction between the two users in the unit time is P, then the familiarity value corresponding to the information interaction between the two users in the unit time is the largest. Pmax, Pmax<P*Y (Y is the maximum number of information exchanges between two clients in unit time, such as assuming that the unit time is 1 day, 90 information interactions are performed, then Pmax=90P) It is possible to calculate the familiarity between the two clients, namely: X1=N1*M1+Min(Y*P, Pmax).

In the step 103, since the number of users in the social network is in the order of one million, the distributed server pre-stores the inverted index file (Inverted index) in the embodiment, of course, the pre-stored inverted index file is only one Preferably, in this embodiment, the time when the inverted index file is established is not limited, or the inverted index file is created after the identification information A and B are extracted, and the inverted index is also often referred to as an inverted index and a file is placed. Or reverse file, is an index method, generally used to store the storage location of a word (as the index Key) in a document or a group of documents (index field value VALUE) under full-text search. Mapping. In this embodiment, only the socialized network in FIG. 3 is taken as an example. In the inverted index file, the identification information A and the identification information B that are mutually bound are used (the (AB) indicates the binding information A and the binding information. The identification information B) is the key of the index, for example, the key is (AB), and the social attribute information shared by the client identified as A and the user identified as B is indexed as VALUE, wherein the social attribute information is represented by a user. The social network users have the attributes in the social network. These social attribute information can be registered when the user joins the social network. For example, the location where the registration is completed is: Hangzhou, the company is Company A can also be the information generated during the activities in the social network: belonging to a certain World of Warcraft group. These social attribute information can be obtained from, for example, a user log, or obtained from a database for storing user registration information, and then extract common social attribute information from social attribute information of different users. For example, the VALUE of the index is {"location" => "Hangzhou", "company" => "company", "same name" => "male", "industry" => "hardware electronics", "game name" = > "World of Warcraft"}, the inverted index file stored in server 1 is shown in Table 3.

The social network server obtains (AB) according to the identifier information A and the identification information B extracted from the authentication request message, and determines the storage index record from the server 1, the server 2, and the server 3 that store the inverted index file. The server whose keyword is (AB) is the inverted index file server.

In step 104, the social network server extracts the index record with the keyword (AB) from Table 3, and extracts the corresponding VALUE (the user identified as A and the user identified as B) Attribute Information) {"Location" => "Hangzhou", "Company" => "Company", "Surname" => "Men", "Industry" => "Hardware Electronics", "Game Name" => "World of Warcraft"}.

The social network server extracts the index record with the keyword (A-B), and extracts the relationship chain information between the client identified as A and the client identified as B. The relationship chain information between the client A and the client B is used as an index of the VALUE. The relationship chain information is used to indicate that the two clients have an indirect social network relationship with each other. For example, the client and the identifier identified as A are The user end of D has a certain social relationship, the relationship type is 2, the client D and the client B have a certain social relationship, the relationship type is 1, and the key VALUE of the (AB) index is {(AD, relationship). Type 2), (DB, relationship type 1)}, as for client A and client C have a certain social relationship, relationship type is 2, client C and client B have a certain social relationship, the relationship type is 1, VALUE of another index of (AB) is {(AC, relationship type 2), (CB, relationship type 1)}, and the inverted index file stored in the server 1 is as shown in Table 4.

Table 4

In step 105, the social network server will extract the {"location" => 'Hangzhou", "company" => "company A", "single name" => "male", "industry" => "Hardware Electronics", "Game Name" => "World of Warcraft"}, sent to the client identified as B. By {"Location" => "Hangzhou", "Company" => "Company A", "Surname "=>"Men", "Industry" => "Hardware Electronics", "Game Name" => "World of Warcraft"} indicates that the user bound to the client identified as A is bound to the client identified as B. The common attributes that users have in a social network.

At the same time, the social network server forwards the authentication request message to the client identified as B, and carries the above-mentioned common social attribute information in the authentication request message {"location" => "Hangzhou", "company" => "A Company", "last name" => "male", "industry" => "hardware electronics", "game name" => "World of Warcraft"}. Of course, the social network server may also send an authentication request message and the above-mentioned common social attribute information to the client identified as B, and carry the instructions in the authentication request message and/or the common social attribute information. News. The UE identified as B can know which authentication request message is received by the received common social attribute information, and perform authentication processing on the authentication request message according to the common social attribute information.

Or, the social network server will extract the extracted {AD, relationship type 2), (DB, relationship type 1)} or {AC, relationship type 2), (CB, relationship type 1)}, and send it to the identifier as The client side of B. By {A-D, relationship type 2), (D-B, relationship type 1)} or {A-C, relationship type 2), (C-B, relationship type 1)} represents the relationship chain information between the client A and the client B. For the common relationship chain information, when the social network server forwards the authentication request message to the client identified as B, the authentication request message carries the common relationship chain information, and of course, the social network server can also separately identify the identifier. Sending the authentication request message and the relationship chain information between the client A and the client B, and carrying the description in the authentication request message and/or the "relationship chain information between the client A and the client B" Bind information. The UE identified as B can know which authentication request message is received by the received relationship chain information, and perform authentication processing on the authentication request message according to the relationship chain information.

Further, in step 103, the social network server selects the client C according to a predetermined rule from the client having a direct social network relationship with the client A and the client B, and the social network server The identification information A carried in the authentication request message sent by the client A is modified into the identification information C. After receiving the authentication request message sent by the client A, the social network server finds the identification information A in the authentication request message. And modified to identify the information C, the modified authentication request message includes: the identification information C and some modified text descriptions, the identification information C is used to identify the sending client of the modified authentication request message, and the modified text description may be : "User A requests to join the social relationship list 1". Therefore, the modified authentication request message is: sending the client identifier: C, and the text content “user A requests to join the social relationship list 1”. Send an authentication request message after modifying the identification information to the client B. The identifier information C and some text descriptions included in the authentication request message sent by the original client A are used to indicate that the requesting client B adds the client A to the social relationship list 1 . After the user C is selected through the foregoing predetermined rule, the authentication request message after modifying the identification information may be sent to the user C first, and the social network server receives the OK confirmation message of the response from the user C, and then sends the message to the user. End B sends an authentication request message after modifying the identification information. Otherwise, the authentication request message after modifying the identification information is not sent to the user B.

In step 106, the client identified as B receives the authentication request message sent by the client identified by A and establishes a social relationship in the form of a social relationship verification message block, and displays the social relationship verification message box. {"Location" => "Hangzhou", "Company" => "Company", "Surname" => "Men", "Industry" => "Hardware Electronics", "Game Name" => "World of Warcraft" }.

The second embodiment of the present application is a method for processing an authentication request message in a social network. The method flow is as shown in FIG. 4, and includes: Step 201: A client identified as A uses a social network server to identify the identifier. An authentication request message is generated for the user of B to establish a socialized relationship with the user identified as B.

Step 202: After the social network server learns that the client that is identified by A sends a request to establish a socialized relationship with the user that is identified as B, the authentication information A and the identifier B are obtained. The identification information B of the client.

Step 203: The social network server determines, according to the identification information A and the identification information B, the server 1 with the keyword A and the server with the keyword B from the plurality of servers storing the inverted index file. 2. Of course, if the inverted index file is only stored in one server, this step is not needed. For example, all the index records are stored in the social network server 1, and the index records of the keywords A or B are directly Extracted from the social network server 1.

Step 204: From the server 1, the social network server extracts the social attribute information of the user terminal identified as A in the index record of the keyword A, and extracts the society of the user terminal identified as B from the server 2. Attribute information.

Step 205: Extract common social attribute information from the socialized attribute information of the user end identified as A and the socialized attribute information of the user end identified as B.

Step 206: The social network server sends the extracted common social attribute information to the client identified as B.

Step 207: The client identified as B displays the received socialized attribute information common to the user end that is identified as A and the user end that is identified as B.

In the inverted index file pre-stored in this embodiment, the key with the index information as the index, and the socialized attribute information of the user end with different identifiers are used as the corresponding index VALUE, for example, the information A is used as the key, and the user identified as A is identified. The socialized attribute information is used as the corresponding index VALUE, and the information B is identified as the Key, and the socialized attribute information of the user end of the B is identified as the corresponding index VALUE, and the VALUE of the index A corresponding to the information A is {"location". => "Hangzhou", "Company" => "Company", "Surname" => "Men", "Industry" => "Hardware Electronics", "Game Name" => "World of Warcraft", "Sports Project "=>"Football", occupation"=>"sale", etc., the identification information _ as the index corresponding to the key VALUE is {"location" => "Hangzhou", "company" => "company A", "surname" Don't "=" "Men", "Industry" => "Hardware Electronics", "Game Name" => "World of Warcraft", "Sports Project" => "Table Tennis Ball", Occupation" => "Financial Personnel", etc. }. The social network server finds the common part from the above 2 VALUEs {"location" => "Hangzhou", "company" => "company A", "same name" => "male", "industry ”=>”Hardware Electronics”, “Game Name” => “World of Warcraft”}.

Of course, after step 205, the system may automatically determine the number of pieces of common social attribute information, and if the number of pieces is 10, just exceed the set first threshold of 9, the system will automatically add user A to In the social network relationship list 1 of the user B, if the number of the bars is 5 and just exceeds the set second threshold, the system automatically adds the user A to the social network relationship list 2 of the user B.

The third embodiment of the present application is a device for processing an authentication request message in a social network, and the structure thereof is as shown in FIG. 5, which includes: an obtaining module 301, configured to learn that the first user end sends the second user end to the second user end.
