Furthermore, the term "and/or" as used in this disclosure encompasses any and all possible combinations of the listed items.
In view of the increasing emphasis on protecting user privacy, it has become increasingly difficult to identify terminal devices using unique and non-modifiable identities that relate to the terminal devices. The present disclosure proposes the following technical ideas: the device source of the application access information is identified based on the device identification information which is included in the application access information and is not strong in uniqueness, can be tampered with by technology, and/or is authorized to be friendly, and is combined with the network identification information of the network where the terminal device which is included in the application access information and is associated with the application access information.
Based on the technical conception, the embodiment of the disclosure provides a device source identification method and device. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a flowchart illustrating a device source identification method 100 according to an embodiment of the present disclosure. As shown in fig. 1, the device source identification method 100 may include: step S102, acquiring a plurality of pieces of application access information, wherein each piece of application access information in the plurality of pieces of application access information comprises network identification information about a network where a terminal device associated with the piece of application access information is located and device identification information about the terminal device associated with the piece of application access information; step S104, dividing the pieces of application access information into one or more application information sets based on the pieces of network identification information included in the pieces of application access information, wherein the application access information in each application information set includes the same network identification information; and step S106, for each of the one or more application information sets, dividing the application information set into one or more application information subsets based on a plurality of pieces of device identification information included in the application access information in the application information set, and identifying the application access information in each application information subset as originating from the same terminal device, wherein the application access information in each application information subset includes the same device identification information.
In the device source identification method according to the embodiment of the present disclosure, the device source of the application access information is identified in combination with both the network identification information and the device identification information included in the application access information, which helps to avoid erroneous identification due to technical tampering or non-uniqueness of the device identifier when the device source of the application access information is identified with a single device identifier, resulting in higher reliability of the identification result.
In some embodiments, pieces of application access information for one or more terminal devices for one or more applications may be obtained from one or more application servers. Each piece of application access information may include one or more pieces of network identification information and one or more pieces of device identification information. Each piece of network identification information may include at least one of the following items of network information: internet protocol address (IP), base station number (CID), location Area Code (LAC), basic Service Set Identifier (BSSID), and wireless network address (WiFi-MAC). Each piece of device identification information may include at least one of the following items of device information: system start-up time (uptime), bluetooth address, network card physical address (MAC), advertisement identifier (IDFA/IDFV), and international mobile equipment identification number (IMEI).
Here, most of the network information items and the device information items are authorization-friendly (i.e., the user is allowed to acquire in most cases), and interruption of the device source identification flow due to lack of individual information in the application access information can be avoided.
In some embodiments, step S104 may include: for any two pieces of application access information in the pieces of application access information, judging whether the two pieces of application access information comprise at least one identical network information item and judging whether the information of the at least one identical network information item is identical, if so, judging that the two pieces of application access information comprise identical network identification information, and dividing the two pieces of application access information into the same application information set. For example, the application access information 1 includes an internet protocol address IP1, a base station number CID1, and a wireless network address WiFi-MAC1, the application access information 2 includes the internet protocol address IP1 and the wireless network address WiFi-MAC1, and since the application access information 1 and 2 each include two network information items of the internet protocol address and the wireless network address and information of the two network information items is the same, it can be determined that the two pieces of application access information include the same network identification information, and the two pieces of application access information can be divided into the same application information set.
Alternatively, in some embodiments, step S104 may include: for each piece of application access information in the pieces of application access information, calculating a weighted sum of network information items included in the piece of application access information; the weighted and equal application access information is divided into the same application information set, wherein the same network information item has the same weight value in different application access information, and different network information items have different weight values in the same application access information. Here, it is not necessary to include the individual network information items one by one of the plurality of pieces of application access information, and application access information originating from the same network section can be recognized relatively quickly.
Alternatively, in some embodiments, step S104 may include: dividing the pieces of application access information into one or more application information groups based on at least one network information item of internet protocol address, base station number and location area code in the pieces of network identification information included in the pieces of application access information; each of the one or more application information groups is further partitioned based on at least one of a basic service set identifier and a wireless network address in a plurality of pieces of network identification information included in the plurality of pieces of application access information to partition the one or more application information groups into one or more application information sets. Here, the application program access information from the same larger network section is first identified based on at least one network information item in the internet protocol address, the base station number and the location area code, and then the application program access information from the same smaller network section in the application program access information from the same larger network section is identified based on at least one network information item in the basic service set identifier and the wireless network address, so that the accuracy of identifying the application program access information from the same terminal device is potentially improved.
In some embodiments, step S106 includes: for any two pieces of application access information in each application information set, judging whether the two pieces of application access information comprise at least one identical equipment information item and judging whether the information of the at least one identical equipment information item is identical, if so, judging that the two pieces of application access information comprise identical equipment identification information, and dividing the two pieces of application access information into the same application information subset. For example, the application access information 1 includes a system start time uptime1, a bluetooth address 1, and a network card physical address MAC1, the application access information 2 includes the bluetooth address 1 and the network card physical address MAC1, and since the application access information 1 and 2 each include two device information items of the bluetooth address and the network card physical address and the information of the two device information items is the same, it can be determined that the two pieces of application access information include the same device identification information, and the two pieces of application access information can be divided into the same subset of application information.
Alternatively, in some embodiments, step S106 may include: for each set of application information, calculating a weighted sum of device information items included in each piece of application access information in the set of application information; the weighted and equal application access information is divided into the same subset of application information, wherein the same device information item has the same weight value in different application access information, and different device information items have different weight values in the same application access information. Here, it is not necessary to include the respective device information items one by one of the plural pieces of application access information, and application access information originating from the same terminal device can be recognized relatively quickly.
Alternatively, in some embodiments, step S106 may include: for each application information set, dividing the application information set into one or more application information clusters based on a system start time in a plurality of pieces of device identification information included in application access information in the application information set; one or more application information clusters are reorganized into one or more application information subsets based on at least one device information item of Bluetooth address, network card physical address, advertisement identifier, and International Mobile Equipment identity in a plurality of pieces of device identification information included in the application access information in the application information set. The application program access information from the terminal equipment with the same system starting time is firstly identified based on the system starting time, then the application program access information from the same terminal equipment is identified based on at least one equipment information item in the Bluetooth address, the network card physical address, the advertisement identifier and the international mobile equipment identification code, multiple association relations among the equipment information items included in the application program access information are fully considered, and the equipment identification is carried out based on a plurality of equipment information items, so that interruption of the equipment source identification process caused by lack of individual equipment information items is reduced.
In the device source identification method according to the embodiment of the present disclosure, the network identification information and the device identification information included in the application access information are used in series to identify the application access information originating from the same terminal device, and the reliability of the identification result is higher. In addition, by identifying application access information associated with the same terminal device, information about the APP usage of the terminal device can be analyzed to obtain a user representation (e.g., usage habit and hobby information) of the terminal device user, thereby facilitating targeted recommendation of the APP and/or specific functions in the APP to the terminal device user. Further, after identifying the terminal device from which the application access information comes, the large-scale information generated by the terminal device can be analyzed by utilizing the large-data technology, so that a more accurate user portrait of the terminal device user is obtained.
Fig. 2 is a diagram illustrating an example process of identifying a device source of application access information using the device source identification method illustrated in fig. 1. A device source identification method according to an embodiment of the present disclosure is further described below with reference to examples. In the example shown in fig. 2:
In step S102, seven pieces of application access information (the seven pieces of application access information are identified as CUID1, CUID2, CUID3, CUID4, APP a, APP B, APP C, respectively) are acquired.
In step S104, the seven pieces of application access information are divided into a plurality of application information groups according to the internet protocol addresses included in the application access information CUID1, CUID2, CUID3, CUID4, APP a, APP B, APP C. Specifically, since the application access information CUID1, CUID2, APP a, APP B, and APP C include the same internet protocol address IP1, the application access information CUID3 and CUID4 include the same internet protocol address IP2, the application access information CUID1, CUID2, APP a, APP B, and APP C are divided into the same application information group 1, and the application access information CUID3 and CUID4 are divided into the same application information group 2 (not shown). Then, for the application information group 1, the application information group is divided into a plurality of application information sets according to the basic service set identifier included in the application access information in the application information group. Specifically, since the application access information CUID1, APP a, APP B, APP C includes the same basic service set identifier BSSID1 and the application access information CUID2 includes the basic service set identifier BSSID2, the application access information CUID1, APP a, APP B, APP C is divided into the application information set 1 and the application access information CUID2 is divided into the application information set 2 (not shown).
In step S106, for the application information set 1, the application information set is first divided into a plurality of application information clusters according to the system start time included in the application access information in the application information set. Specifically, since the application access information CUID1 and APP C include the same system start time uptime1, the application access information APP a includes the system start time uptime2, and the application access information APP B includes the system start time uptime3, the application access information CUID1 and APP C are divided into the application information cluster 1, the application access information APP a is divided into the application information cluster 2, and the application access information APP B is divided into the application information cluster 3. And then, reorganizing the application information clusters according to the network card physical address and/or the advertisement identifier included in the application access information in the application information clusters 1-3 to finally obtain an application information subset 1, wherein the application information subset comprises application access information CUID1, APP A, APP B and APP C. That is, the application access information CUID1, APP a, APPB, and APP C are recognized as coming from the same terminal device.
It should be added that the application information group 2 only includes the application access information CUID3 and CUID4, and it may be determined whether they are from the same terminal device directly based on the device identification information included in the application access information CUID3 and CUID 4. In addition, since the application information set 2 includes only the application access information CUID2, it is not necessary to perform the subsequent identification processing based on the device identification information included in the application access information CUID 2. Here, for clarity and brevity, the application information group 2 and the application information set 2 are not shown in fig. 2.
It should be noted that, in the practical application process, the network identification information acquired in different scenarios is not limited to include only the above-mentioned network information items, but may include other network information items that are easy to obtain user authorization and relatively fixed; the device identification information obtained under the different operating systems may also include other device information items.
