Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The applicant first introduces application scenarios to which embodiments of the present invention relate.
As shown in fig. 1, a public third party platform 200 is created on an open platform 100. The platform 200 calls each service interface to implement a corresponding service on behalf of the public number 300 by obtaining the authorization of the interface capability of the public number 300.
The public number 300 is an application account number applied by a developer or a merchant on a wechat public platform, a large number of wechat users (also called fans) are concerned under each public number 300, and for the same wechat user, different openids are allocated to the wechat user under different public numbers 300 by the system. Therefore, how to accurately identify the same WeChat user under different public numbers is a technical problem to be solved by the invention.
As shown in fig. 2, a user identity identification method provided in an embodiment of the present invention is specifically applied to a public third party platform, and the method may include:
In the embodiment of the invention, the interface calling identifier of the public number is the bill access _ token of the public number generally, and the public number third party platform takes the bill access _ token of the public number as the interface calling certificate to call the interface.
Taking the public number third party platform as a national double public number third party platform as an example, firstly, the national double public number third party platform needs to receive authorization information of different public numbers. For example, the third-party platform of the national double public number initiates an authorization request to the public number, and when the third-party platform of the national double public number receives a determined authorization result returned by the public number, the third-party platform of the national double public number obtains the authorization of the interface capability of the public number. For another example, the public number actively sends a determined authorization result to the national duplex public third party platform, and the national duplex public third party platform receives and responds to the determined authorization result, so that the authorization of the interface capability of the public number is obtained.
Each public number authorized to the dual-public third-party platform in China has a refresh _ access _ token of an authorization code and a refresh bill to be called back to the dual-public third-party platform in China. The ticket access _ token of the public number can be continuously refreshed through the refresh _ access _ token, so that the ticket access _ token of each public number of the authorized country dual-public-number third-party platform can be acquired.
102, calling the identifier according to the interface of each public number, and respectively acquiring user information under each public number, wherein the user information at least comprises head portrait link information.
After the ticket access _ token of each public number is acquired, the WeChat officer provides an interface for acquiring the user detailed information, and requests the WeChat server to acquire the user detailed information of the user by using the interface, so that the user information (also called fan information) under each public number can be acquired respectively.
The specific implementation method of step 102 in the embodiment of the invention can be seen in the technical text of the WeChat public platformThe gear is arranged on the front end of the main shaft,https:// mp.weixin.qq.com/wikit＝resource/res_main&id＝mp1421140839the inventor is not described herein in detail.
Specifically, the user information acquired in the embodiment of the present invention may include the content shown in table 1 below.
TABLE 1
The preset method is preferably MD5(Message-Digest Algorithm 5), and MD5 processing is performed on the image file to obtain an MD5 value.
In the actual application process, when the user uploads the head portrait, the system processes the uploaded head portrait according to a preset processing mode. For example, the user micro signal and the uploaded head portrait are combined and then subjected to pixel processing, thereby generating an image file. Thus, even if different users upload the same head portrait, after the processing of the system background, the image files generated corresponding to each user are completely different. Therefore, an image file acquired to the user through the avatar link information headimgurl field can uniquely identify the user.
In the embodiment of the invention, the image file of the user can be acquired by the national duplex public third party platform through the head portrait link information headimgurl field, wherein the image file at least comprises the head portrait used by the user, and the image file is used for identifying the unique user. Further, the national double public third party platform performs MD5 processing on the acquired image file to obtain an MD5 value.
And step 104, determining the users with the same processing result as the same user.
According to the embodiment of the invention, the MD5 value is obtained after the MD5 processing is carried out on the image file, and users with the same MD5 value are determined as the same user.
MD5 is a hash function widely used in the field of computer security, and MD5 can generate a unique "digital fingerprint", MD5 value, for any file (regardless of size, format, number). If any change occurs to the file, the value of MD5 changes.
Therefore, in the embodiment of the present invention, if MD5 values obtained after MD5 processing of an image file are the same, it indicates that users corresponding to the image file are the same user, and thus the same user with different public numbers can be accurately identified.
The user identity identification method provided by the embodiment of the invention obtains the user information under each public number respectively by obtaining the interface calling identification of each public number of the authorized public number third-party platform, wherein the user information at least comprises head portrait linking information; further acquiring an image file of the user according to the head portrait linking information, and performing MD5 processing on the image file to acquire an MD5 value; and finally, users with the same MD5 value are determined as the same user, so that the same micro credit user under a plurality of different public numbers is identified.
On the basis of the above embodiment, as shown in fig. 3, after step 104, the method may further include:
and 105, acquiring user data of the same user under different public numbers.
Wherein the user data may include a user's browsing history, a history of interactions with public numbers, etc.
The user representation is a tagged user model abstracted and extracted according to social attributes, living habits, consumption behaviors and the like of the user. The core task of constructing the user representation is to label the user based on the refined feature identifiers from the user's information analysis. For example, user A may be tagged with the interest tag "car" based on, for example, user A's age, gender, education level, and data from frequent browsing of the car's website.
Corresponding to the embodiment of the method, the invention also provides a user identity recognition device.
As shown in fig. 4, a user identification apparatus provided in an embodiment of the present invention may include: a first acquisition module 10, a second acquisition module 20, a third acquisition module 30, a processing module 40 and a determination module 50,
