[0083] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0084] The present application embodiment provides a user identification method. In the first embodiment of the user identification method of the present application, refer to Figure 1 , applied to a terminal, the terminal is in communication connection with a management entity, the terminal includes a first application entity, and the user identification method includes:

[0085] Step S10, when it is detected that the target user uses the first application entity, obtaining a random user identifier of the target user on the first application entity side;

[0086] Step S20, based on the random user identifier, determining the identification domain name of the target user on the first application entity side, so that the preset target device managed by the management entity can access the identification domain name, and associating the identification domain name with the preset terminal unique device identifier;

[0087] Step S30: receiving a preset target device managed by the management entity, associating the identification domain name with a preset terminal unique device identifier, and then reporting first association information.

[0088] The specific steps are as follows:

[0089] Step S10, when it is detected that the target user uses the first application entity, obtaining a random user identifier of the target user on the first application entity side;

[0090] In this embodiment, it should be noted that the terminal is communicatively connected to the management entity, wherein the terminal may be a smart phone, an IPAD, or a PC and other terminals, wherein the terminal includes a first application entity and other second application entities, and in this embodiment, the application entity is a business application or business function usage entity, such as Youku (application 1), iQiyi (application 2) and other usage entities, and in this embodiment, the management entity is a network device (local area network device) such as a router, an optical modem, an electric power modem, and a switch, wherein the management entity is communicatively connected to the terminal.

[0091] When it is detected that the target user uses the first application entity, a random user identifier of the target user on the first application entity side is obtained.

[0092] The method of detecting whether the target user uses the first application entity is as follows:

[0093] Method 1: Determine whether the target user is logged in to use the entity. After determining that the target user is logged in to use the entity, further determine whether the target user is in the user interface of the use entity. If the target user is in the user interface of the use entity, determine that the target user is in the use state of the first application entity. If it is determined that the target user is not in the user interface of the use entity, determine that the target user is not in the use state of the first application entity.

[0094] Method 2: Determine whether the target user is logged in to the usage entity. After determining that the target user is logged in to the usage entity, further determine whether the usage entity is in the background running state. If it is determined that the usage entity is not in the background running state, determine that the target user is in the usage state of the first application entity. If it is determined that the usage entity is in the background running state, determine that the target user is not in the usage state of the first application entity.

[0095] In this embodiment, when it is detected that the target user uses the first application entity, a method of obtaining a random user identifier of the target user on the first application entity side includes:

[0096] Method 1: when it is detected that the target user uses the first application entity, a random user identifier of the target user on the first application entity side is obtained through an identifier generation rule preset in the first application entity;

[0097] Mode 2: When it is detected that the target user uses the first application entity, the random user identifier of the target user generated by the identifier generation system is received through the first application entity to obtain the random user identifier of the target user on the first application entity side.

[0098] In this embodiment, it should be noted that the first user entity can generate a random identifier for the user (the user's actual smart device end), such as the random identifier can be: yonghu1. In this embodiment, the random identifier can also be signed at the first user entity, specifically, using the private key signature to obtain qianming_yonghu1;

[0099] Alternatively, in this embodiment, the random identifier may also be signed by a third party at the first user entity, specifically, qianming_yonghu1 is obtained by signing with a private key;

[0100] Step S20, based on the random user identifier, determining the identification domain name of the target user on the first application entity side, so that the preset target device managed by the management entity can access the identification domain name, and associating the identification domain name with the preset terminal unique device identifier;

[0101] In this embodiment, after obtaining the random user identifier, the identification domain name of the target user on the first application entity side is determined based on the random user identifier. It should be noted that in this embodiment, the identification domain name can not only uniquely identify the target user, but also uniquely identify the first application entity, that is, the same user has different identification domain names on different application entity sides, and different users on the same application entity side have different identifiers.

[0102] Based on the random user identifier, a method for determining the identification domain name of the target user on the first application entity side may be: obtaining a first MD5 value corresponding to the random user identifier and a second MD5 value of the identification domain name on the first application entity side, and based on the first MD5 value and the second MD5 value, generating the identification domain name of the target user on the first application entity side according to a preset generation function (inputting the first MD5 value and the second MD5 value into the function and calculating).

[0103] The step of determining the identification domain name of the target user on the first application entity side based on the random user identifier includes:

[0104] Step S21: The random user identifier and the preset domain name of the first application entity are combined according to a preset composition rule to form an identifier domain name of the target user at the first application entity side.

[0105] In this embodiment, the random user identifier and the preset domain name of the first application entity are combined according to a preset composition rule to form an identification domain name of the target user on the first application entity side. The composition method can be a head-to-tail composition method or a fusion composition method. For example, a random identifier (qianming_yonghu1) and a "using entity" domain name (router.youku.com) are used to form an identification domain name, such as: qianming_yonghu1.router.youku.com.

[0106] Or, for example, a random identifier (qianming_yonghu1) and a "using entity" domain name (router.youku.com) are used to form an identification domain name, such as: qianming_yonghu1.youku.com.

[0107] Based on the random user identifier, determine the identification domain name of the target user on the first application entity side, so that the preset target device managed by the management entity can access the identification domain name, and associate the identification domain name with the preset terminal unique device identifier, wherein the management entity, such as a router's downstream device, accesses the domain name on the browser or APP side of the first user entity, qianming_yonghu1.router.youku.com. After the preset target device managed by the management entity accesses the identification domain name, it obtains the random user identifier in the identification domain name, and verifies the random user identifier to verify whether it is sent by the first user entity, rather than a forged identifier.

[0108] In this embodiment, the preset target device (or its subordinate device) managed by the management entity accesses the identification domain name and associates the identification domain name with the preset terminal unique device identifier. Specifically, for example, if the preset terminal unique device identifier is a MAC address, the identification domain name is associated with the MAC address, if the preset terminal unique device identifier is an IMEI / MEID address, the identification domain name is associated with the IMEI / MEID address, if the preset terminal unique device identifier is an IMSI address, the identification domain name is associated with the IMSI address, and if the preset terminal unique device identifier is a SIM address, the identification domain name is associated with the SIM address.

[0109] In this embodiment, the preset target device managed by the management entity accesses the identification domain name, associates the identification domain name with the preset terminal unique device identifier, and then encrypts the identification domain name. For example, the decrypted data is encrypted to obtain jiami_yonghu1.

[0110] It should be noted that, in this embodiment, the preset target device managed by the management entity also accesses other identification domain names of other application entities, and associates the other identification domain names with the preset terminal unique device identifier.

[0111] Step S30: receiving a preset target device managed by the management entity, associating the identification domain name with a preset terminal unique device identifier, and then reporting first association information.

[0112] In this embodiment, the first user entity receives the preset target device managed by the management entity, associates the identification domain name with the preset terminal unique device identifier, and then reports the first association information, that is, the first user entity activates a reporting service, that is, the first application entity side obtains the information of the preset terminal unique device identifier and the networking channel information through the activated reporting service, and the "management entity" transmits the identifier jiami_yonghu1 to the "user entity" through the interface to indicate that the user is surfing the Internet through the actual device of the management entity. In this embodiment, the first user entity receives the preset target device managed by the management entity, associates the identification domain name with the preset terminal unique device identifier, and then reports the first association information, thereby realizing the association with the terminal unique device identifier.

[0113] Reference Figure 2 , after the step of receiving the preset target device managed by the management entity, associating the identification domain name with the preset terminal unique device identifier, and reporting the first association information, the method includes:

[0114] Step S40, acquiring user information of the target user, wherein the user information includes a service expiration time of the first application entity for the target user;

[0115] In this embodiment, the terminal also obtains user information of the target user, specifically, obtains user information of the target user on the first user entity side, wherein the user information includes the service expiration time of the first application entity for the target user, specifically, for example, the membership expiration time of the target user, or the annual card expiration time of the target user. In addition, the user information also includes information such as the user's viewing content and viewing frequency.

[0116] Step S50: Send the user information to the management entity so that the management entity can complete various identifications of the target user in preset dimensions.

[0117] The user information is sent to the management entity so that the management entity can complete the various identifications of the target user in preset dimensions. That is, in this embodiment, the first user entity can provide the management entity with information such as the effective time or the expiration time of the user membership to complete all feature identifications of the target user. Specifically, the user information is sent to the management entity so that the management entity can complete the various feature identifications of the target user in preset dimensions such as interest dimension, type dimension, etc.

[0118] After the step of receiving the preset target device managed by the management entity, associating the identification domain name with the preset terminal unique device identifier, and reporting the first association information, the method includes:

[0119] Step S60, receiving user characteristic information of the user determined by the preset target device based on the first association information and second association information of other second application entities;

[0120] Step S70: making targeted recommendations based on the user characteristic information.

[0121] In this embodiment, the user characteristic information of the user determined by the preset target device based on the first association information and the second association information of other second application entities is also received, wherein, that is, in this embodiment, the management entity associates the association information of different user entities through the MAC address to obtain more complete user characteristic information of the target user, so as to make targeted recommendations based on the user characteristic information.

[0122] The present application obtains the random user identifier of the target user on the first application entity side when it is detected that the target user uses the first application entity; determines the identification domain name of the target user on the first application entity side based on the random user identifier, so that the preset target device managed by the management entity can access the identification domain name, and associates the identification domain name with the preset terminal unique device identifier; receives the preset target device managed by the management entity, associates the identification domain name with the preset terminal unique device identifier, and reports the first association information. In the present application, when it is detected that the target user uses the first application entity, a random user identifier is generated to generate an identification domain name, and then, the identification domain name is associated with the preset terminal unique device identifier for the preset target device managed by the management entity, and reports the association information, that is, in the present application, the user identifier of the business application is associated with the preset terminal unique device identifier by generating a domain name, so that different business applications can be connected based on the preset terminal unique device identifier to realize accurate unique positioning or unique identification of users in cross-Internet business, and solve the technical problem that it is difficult to accurately uniquely locate or uniquely identify users under the existing account system of different business applications.

[0123] Further, based on the first embodiment of the present application, another embodiment of the present application is provided. In this embodiment, when it is detected that the target user uses the first application entity, before the step of obtaining the random user identifier of the target user on the first application entity side, the method includes:

[0124] Step S01, generating a first asymmetric key on the first application entity side;

[0125] Step S02: sending the first public key in the first asymmetric key to the management entity, so that a preset target device of the management entity can subsequently authenticate the first application entity.

[0126] In this embodiment, a first asymmetric key (such as a pair of RSA certificates) is also generated on the first application entity side for identity verification with the management entity. Specifically, the first public key in the first asymmetric key is sent to the management entity for subsequent authentication of the first application entity by a preset target device of the management entity, wherein the identity authentication may be performed in the process of obtaining a random user identifier after the preset target device managed by the management entity accesses the identification domain name. The purpose of identity authentication through the first asymmetric key is to verify whether the random user identifier is sent by the user entity, rather than a forged identifier.

[0127] Among them, in this embodiment, the step of determining the identification domain name of the target user on the first application entity side based on the random user identifier so that the preset target device managed by the management entity can access the identification domain name, and associating the identification domain name with the preset terminal unique device identifier includes:

[0128] Step S22: determining the identification domain name of the target user on the first application entity side based on the random user identifier;

[0129] Step S23, receiving a second asymmetric key generated by the preset key system based on the identification domain name trigger, encrypting the random user identifier based on the private key in the second asymmetric key, so that the preset target device managed by the management entity can access the encrypted identification domain name, and decrypting the random user identifier in the identification domain name based on the second public key in the second asymmetric key;

[0130] The management entity associates the decrypted random user identifier with a preset terminal unique device identifier.

[0131] In this embodiment, a method for identity authentication is also provided. In this identity authentication method, the second asymmetric key is generated by triggering an identification domain name, and is generated by triggering a preset key system based on the identification domain name. Since the preset key system triggers the generation of the second asymmetric key based on the identification domain name, and encrypts the random user identifier based on the private key in the second asymmetric key, the first application entity side may not land or save the private key in the second asymmetric key, but directly encrypt the random user identifier, thereby improving the security performance. In addition, in this embodiment, the preset target device managed by the management entity accesses the encrypted identification domain name, and decrypts the random user identifier in the identification domain name based on the second public key in the second asymmetric key; wherein the management entity associates the decrypted random user identifier with the preset terminal unique device identifier to complete the association of the random user identifier with the preset terminal unique device identifier in a secure state.

[0132] In this embodiment, the identification domain name of the target user on the first application entity side is determined based on the random user identifier; the second asymmetric key generated by the preset key system based on the identification domain name is received, and the random user identifier is encrypted based on the private key in the second asymmetric key, so that the preset target device managed by the management entity can access the encrypted identification domain name, and the random user identifier in the identification domain name is decrypted based on the second public key in the second asymmetric key; wherein the management entity associates the decrypted random user identifier with the preset terminal unique device identifier. In this embodiment, the random user identifier is associated with the preset terminal unique device identifier in a secure state.
