Embodiment 1

[0059] Embodiment 1 of the present invention provides a kind of ID associating method, the mark of setting corresponding IP same situation is I, the mark of corresponding IP different situation is i, the mark of corresponding Host-Key identical and the value value of Host-Key identical situation is V, corresponding to the case where the Host-Key is the same and the value of the Host-Key is different is identified as v, such as figure 1 As shown, the methods include:

[0060] In step 201, the identification corresponding to the same IP and the same Host-Key and the same value of the Host-Key is set to IV; the identification corresponding to the same IP and the same Host-Key and the different value of the Host-Key Set it to Iv; set the flag corresponding to the situation where the IP is different and the Host-Key is the same and the value of the Host-Key is the same as iV; the flag corresponding to the situation where the IP is different and the Host-Key is the same and the valu...

Embodiment 2

[0092] In the embodiment of the present invention, when using the method described in Example 1 for testing, especially when further searching for a unique ID in Case 2 of Example 1, a problem was found, refer to the example in Table 2 below:

[0093] Table II:

[0094] Host key value IV IV iV iv dns.weixin.qq.com uin 1305491620 50 3 1188 24332

[0095] The key "uin" in Table 2 has been verified to be a WeChat ID. It can be seen that when the iV is at the maximum value, there are 1188 identical WeChat IDs under different IPs, which is inconsistent with the actual situation. After checking, these 1188 WeChat IDs appear in different The same micro-signal between IPs is "0", which is obviously not a real micro-signal, but a special value. Therefore, in order to avoid similar statistical deviations in other keys, the next largest count value is selected as the final statistical result for the four counts, and the results are very good after i...

Embodiment 3

[0110] In the embodiment of the present invention, examples are used to show the possible situations of establishing an association relationship. Compared with Embodiment 1, a method of how to establish an association relationship when the keys are different but the values ​​are the same is added.

[0111] Use the traffic of the device as the learning material, and match the ID list that uniquely identifies the device obtained by the above method. If some IDs are found to appear in the same traffic, then these IDs are hard associations or physical associations. That is, if HostA:KeyA, HostA:KeyB...HostA:KeyN appear in the same device traffic, when HostA:KeyA=ValueA, HostA:KeyB=ValueB, HostA:KeyN=ValueN are matched in the learning materials, then It can be concluded that the N Values ​​belong to the same user, so there is an association between the different IDs. That is, the ID-Value set of X device [HostA:KeyA=ValueXA, HostA:KeyB=ValueXB, ... HostA:KeyN=ValueXN]. Similarly, ...

Abstract

The invention relates to the technical field of the Internet, and provides an ID association method and device. The method includes setting the flag corresponding to the same IP and the same Host-Key and the same value of the Host-Key as IV; setting the flag corresponding to the case of the same IP and the same Host-Key and different values ​​of the Host-Key Iv; set the flag corresponding to the situation where the IP is different and the Host-Key is the same and the value of the Host-Key is the same as iV; set the flag corresponding to the situation where the IP is different and the Host-Key is the same and the value of the Host-Key is different For iv; calculate the score for each group of Host-Key, so as to filter out the ID. By associating independent device IDs, the present invention can more accurately detect the number of devices and improve the analysis accuracy of the same object.

Description

【Technical field】 [0001] The invention relates to the technical field of the Internet, in particular to an ID association method and device. 【Background technique】 [0002] Since technologies such as network sharing detection require an ID that can uniquely identify a device, using this ID can match that the traffic of an IP user is sent by several devices. By matching the traffic sent by a certain IP with the ID that uniquely identifies the device, if N different values ​​are matched, it can be detected that the traffic of this IP is composed of N devices. Traditional device ID detection methods handle ID items independently and cannot be associated. For example, five different values ​​are detected using the ID of the MAC address in the traffic of an IP user, indicating that the IP traffic is composed of five different devices. Three different values ​​were detected using the ID of the mobile phone number, indicating that the IP traffic is composed of three different dev...
