[0002] A device fingerprint refers to device characteristics or unique device identifiers that can be used to identify the device.

These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the protection scope of this application.

[0068] The collection, storage, use, processing, transmission, provision, and disclosure of user data and other information involved in the embodiments of this application all comply with the provisions of relevant laws and regulations and do not violate public order and good customs.

[0069] It should be noted that although the terms "first", "second", etc. are used to describe various information in the embodiments of this application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. Optionally, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0070] It should be understood that the terms "comprising" and "including" indicate the presence of the stated features, steps, operations, but do not exclude the presence, occurrence, or addition of one or at least one other feature, step, operation.

[0071] For ease of understanding, the nouns involved in this application are first explained:

[0072] Device fingerprint factor: including the operating system type of the terminal device, identification code (International Mobile Equipment Identity, IMEI), network card hardware address (Media Access Control, MAC) web address, etc. Through a specific hashing algorithm, the device fingerprint factor can be converted into a feature string to be used as the device fingerprint.

[0073] Device fingerprint drift: the process in which the device fingerprint changes due to the change of the device fingerprint factor used to calculate the device fingerprint over time.

[0074] Terminal device: It can be a device that provides voice / data connectivity to users. For example, it can be a handheld device, a vehicle-mounted device, etc. with wireless connection capabilities. Currently, some examples of terminal devices can be: mobile phone, pad, computer with wireless transceiver function (such as laptop computer, handheld computer, etc.), mobile internet device (MID), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication function, computing device or other processing devices connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a 5G network or terminal device in a future evolved public land mobile network (PLMN), etc.

[0075] For the sake of easy understanding, the following will be combined with Figure 1 to illustrate the application scenarios applicable to the embodiments of this application.

[0076] Figure 1 It is a schematic diagram of an application scenario provided for the embodiments of this application. Please refer to Figure 1 , which includes a server 101 and a terminal device 102. The terminal device 102 can report the device fingerprint factor and device fingerprint of the terminal device to the server 101, and the server 101 can store the received device fingerprint factor and device fingerprint of the terminal device in a database.

[0077] It should be noted that Figure 1 it is only a schematic diagram of an application scenario and does not constitute a limitation on the applicable scenarios of the technical solutions provided by this application. For example, the application scenarios of the embodiments of this application can include multiple terminal devices or multiple servers.

[0078] In the related art, the device fingerprint factors may change as follows:

[0079] 1. The information for identifying the device is updated. For example, before and after the terminal device system is upgraded, the application will obtain a different unique identifier.

[0080] 2. The information for identifying the device is empty. When the terminal device uninstalls / reinstalls the application, or the authorization information is inconsistent during the use of the application. For example, previously, the application was authorized to obtain the International Mobile Equipment Identity (IMEI), but this time the application is refused to obtain the IMEI, which will result in some device information not being obtained.

[0081] 3. The information for identifying the device is unreliable. For privacy and security considerations, some terminal device manufacturers will construct false device information for applications to use.

[0082] If the device fingerprint factors change, the device fingerprint calculated by the device through these device fingerprint factors will also change, that is, the same device has multiple device fingerprints, thus affecting the stability and uniqueness of the device fingerprint.

[0083] To solve the above technical problems, the present application provides a method, device, equipment and storage medium for determining a device fingerprint. In this method, based on the hardware information and the first fingerprint feature information reported by the terminal device, it is determined whether the device fingerprint drifts, and then the target device fingerprint of the terminal device is determined to ensure the stability and uniqueness of the device fingerprint.

[0084] Next, the technical solution shown in the present application will be described in detail through specific embodiments. It should be noted that the following several embodiments can exist independently or be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0085] Figure 2 is a schematic flowchart of a method for determining a device fingerprint provided by an embodiment of the present application. Please refer to Figure 2 and the method may include:

[0086] S201. Receive a fingerprint acquisition request sent by the terminal device, where the fingerprint acquisition request includes the hardware information and the first fingerprint feature information of the terminal device.

[0087] The execution subject of the present application can be a server or a device fingerprint determination device set in the server. The device fingerprint determination device can be implemented by software or by a combination of software and hardware.

[0088] In other words, it means that the terminal device sends a fingerprint acquisition request to the server.

[0089] In a possible implementation, the terminal device can obtain its own hardware information and first fingerprint feature information when starting up.

[0090] In a possible implementation, the hardware information may include the manufacturer, brand of the terminal device, and the motherboard of the terminal device, etc.

[0091] In a possible implementation, the first fingerprint feature information may refer to the fingerprint feature information that the terminal device currently needs to upload. The first fingerprint feature information may include a first device fingerprint, first device identification information, first system information, and first Digital Rights Management (DRM) information.

[0092] In a possible implementation, the terminal device can send the first fingerprint feature information to the server when starting up or when the first fingerprint feature information is updated.

[0093] In a possible implementation, after the terminal device obtains the first device identification information and hardware information, it can generate a first device fingerprint according to the first device identification information and the hardware information.

[0094] In a possible implementation, the terminal device can convert the hardware information and the first device identification information into a first device fingerprint through a specific hashing algorithm.

[0095] In a possible implementation, the first device identification information may be the current device identification information of the terminal device. The first device identification information may include at least one of IMEI, Media Access Control (MAC) address, Android Identity (Android ID), etc.

[0096] In a possible implementation, the first system information may be the current system information of the terminal device. The first system information may include the system type, system version, etc.

[0097] In a possible implementation, the first DRM information may be the current DRM information of the terminal device. The first DRM information may include DRM support algorithms, DRM providers, DRM versions, and DRM unified identifiers, etc.

[0098] S202. Determine the target device fingerprint of the terminal device according to the hardware information and the first fingerprint feature information.

[0099] The target device fingerprint can be the first device fingerprint or the device fingerprint associated with the hardware information stored in the server.

[0100] S203. Send the target device fingerprint to the terminal device.

[0101] In other words, it means that the terminal device receives the target device fingerprint sent by the server.

[0102] After receiving the target device fingerprint, the terminal device can use the target device fingerprint as its own unique identifier to detect various abnormal behaviors.

[0103] In Figure 2 In the illustrated embodiment, the server receives a fingerprint acquisition request sent by the terminal device. The fingerprint acquisition request includes the hardware information of the terminal device and the first fingerprint feature information. According to the hardware information and the first fingerprint feature information, the server determines the target device fingerprint of the terminal device and sends the target device fingerprint to the terminal device. The server determines whether the device fingerprint of the terminal device drifts according to the hardware information and the first fingerprint feature information of the terminal device. If the device fingerprint drifts, the device fingerprint stored in the server is used as the target device fingerprint. If the device fingerprint does not drift, the first device fingerprint is used as the target device fingerprint, which improves the stability of the device fingerprint, ensures the uniqueness of the device fingerprint, and further provides a more stable basic guarantee for effectively identifying risk devices in anti-fraud and other services.

[0104] In Figure 2 Based on the illustrated embodiment, how the server determines the target device fingerprint of the terminal device will be described in detail below.

[0105] Figure 3 It is a schematic flowchart of another method for determining a device fingerprint provided by an embodiment of the present application.

[0106] Please refer to Figure 3 , the method may include:

[0107] S301. Determine whether there is hardware information in the database.

[0108] If yes, execute S302.

[0109] If no, execute S305.

[0110] S302. Determine whether there is a first device fingerprint in the database.

[0111] If yes, execute S305.

[0112] If no, execute S303.

[0113] S303. Obtain the second fingerprint feature information corresponding to the hardware information in the database.

[0114] The second fingerprint feature information can be the fingerprint feature information of the terminal device stored in the server, which can be referred to as the historical fingerprint feature information of the terminal device.

[0115] In a possible implementation manner, the second fingerprint feature information may include a second device fingerprint, second device identification information, second system information, and second DRM information.

[0116] The second device identification can be generated according to the hardware information and the second device identification information.

[0117] In a possible implementation manner, the second device identification information may be the historical device identification information of the terminal device stored in the server, and the second device identification information may include at least one of IMEI, MAC address, Android ID, etc.

[0118] In a possible implementation manner, the second system information may be the historical system information of the terminal device stored in the server, and the second system information may include the system type, system version, etc.

[0119] In a possible implementation manner, the second DRM information may be the historical DRM information of the terminal device stored in the server, and the second DRM information may include DRM support algorithms, DRM providers, DRM versions, and DRM unified identifiers, etc.

[0120] S304. Determine the target device fingerprint according to the second fingerprint feature information and the first fingerprint feature information.

[0121] In a possible implementation manner, when the server determines the target device fingerprint according to the first fingerprint feature information and the second fingerprint feature information, it may first determine whether the second device identification information in the second fingerprint feature information is consistent with the first device identification information in the first fingerprint feature information to determine the target device fingerprint.

[0122] If the second device identification information in the second fingerprint feature information is inconsistent with the first device identification information in the first fingerprint feature information, then determine the first device fingerprint as the target device fingerprint; if the second device identification information in the second fingerprint feature information is partially consistent with the first device identification information in the first fingerprint feature information, it is also necessary to determine the target device fingerprint according to the system information, DRM information, etc.

[0123] In a possible implementation manner, that the second device identification information and the first device identification information are partially consistent may mean that any one item in the first device identification information is consistent with the corresponding item in the second device identification information.

[0124] Exemplarily, if the first device identification information includes a first IMEI, a first MAC address, and a first Android ID, and the second device identification information includes a second IMEI, a second MAC address, and a second Android ID. The server may first determine whether the first IMEI is the same as the second IMEI; if they are the same, it is also necessary to determine the target device fingerprint based on system information, DRM information, etc.; if they are not the same, it may determine whether the first MAC address is the same as the second MAC address; if they are the same, it is also necessary to determine the target device fingerprint based on system information, DRM information, etc.; if they are not the same, it may determine whether the first Android ID is the same as the second Android ID. If they are the same, it is also necessary to determine the target device fingerprint based on system information, DRM information, etc.; if they are not the same, the first device fingerprint may be determined as the target device fingerprint.

[0125] Also exemplarily, if the first device identification information includes a first IMEI, a first MAC address, and a first Android ID, and the second device identification information includes a second IMEI, a second MAC address, and a second Android ID. The server may determine whether the first IMEI is the same as the second IMEI, whether the first MAC address is the same as the second MAC address, and whether the first Android ID is the same as the second Android ID; if they are completely different, the first device fingerprint may be determined as the target device fingerprint; if they are partially the same, it is also necessary to determine the target device fingerprint based on system information, DRM information, etc.

[0126] In a possible implementation manner, the partial identity in the embodiments of the present application may include complete identity.

[0127] Exemplarily, if the first device identification information includes a first IMEI, a first MAC address, and a first Android ID, and the second device identification information includes a second IMEI, a second MAC address, and a second Android ID. The partial identity between the first device identification information and the second device identification information may mean that only the first IMEI is the same as the second IMEI; or only the first MAC address is the same as the second MAC address; or only the first Android ID is the same as the second Android ID; or the first IMEI is the same as the second IMEI and the first MAC address is the same as the second MAC address; or the first IMEI is the same as the second IMEI and the first Android ID is the same as the second Android ID; or the first MAC address is the same as the second MAC address and the first Android ID is the same as the second Android ID; or the first IMEI is the same as the second IMEI, the first MAC address is the same as the second MAC address, and the first Android ID is the same as the second Android ID.

[0128] S305. Determine the first device fingerprint as the target device fingerprint.

[0129] In Figure 3Based on the illustrated embodiments, the following details how the server determines the target device fingerprint when the first device identification information and the second device identification information are partially consistent.

[0130] Figure 4 It is a flowchart showing another method for determining the device fingerprint provided by the embodiments of the present application.

[0131] Please refer to Figure 4 , the method may include:

[0132] S401. Determine whether the first system information is consistent with the second system information and whether the first device identification information and the second device identification information are completely consistent.

[0133] If so, execute S404.

[0134] If not, execute S402.

[0135] S402. Determine whether the first DRM information is consistent with the second DRM information.

[0136] If so, execute S403.

[0137] If not, execute S404.

[0138] S403. Determine the second device fingerprint as the target device fingerprint.

[0139] When the device fingerprint drifts, the second device fingerprint can be determined as the target device fingerprint, and the second fingerprint feature information can be updated using the first fingerprint feature information.

[0140] S404. Determine the first device fingerprint as the target device fingerprint.

[0141] When the device fingerprint does not drift, the first device fingerprint can be determined as the target device fingerprint. If the corresponding hardware information and fingerprint feature information do not exist in the database, the hardware information and the first fingerprint feature information can be stored in the database. If the corresponding hardware information and fingerprint feature information exist in the database, the fingerprint feature information stored in the database can be updated using the first fingerprint feature information.

[0142] In Figure 4 the illustrated embodiments, in the case of changes in device identification information, system information, etc., it is possible to determine whether the device fingerprint factor drifts according to the DRM information, that is, to determine the target device fingerprint according to the DRM information, improving the stability of the device fingerprint, ensuring the uniqueness of the device fingerprint, and further providing a more stable basic guarantee for effectively identifying risk devices in services such as anti-fraud.

[0143] Based on any of the above embodiments, before the terminal device reports the hardware information and the first fingerprint feature information, it is also necessary to determine whether the device fingerprint is stored locally. If the device fingerprint is stored locally, the locally stored device fingerprint is used as the first device fingerprint. If the device fingerprint is not stored locally, the newly generated device fingerprint is used as the first device fingerprint, and then the first fingerprint feature information is reported to the server. After receiving the first fingerprint feature information, if the server determines that the first device fingerprint in the first fingerprint feature information is the device fingerprint stored locally by the terminal device, it can update the fingerprint feature information corresponding to the device fingerprint in the database and end the process; if it is determined that the first device fingerprint in the first fingerprint feature information is the newly generated device fingerprint of the terminal device, the target device fingerprint of the terminal device is determined according to the hardware information and the first fingerprint feature information.

[0144] In a possible implementation manner, indication information may be added at the end of the first device fingerprint, and the server can determine whether the first device fingerprint is newly generated by the terminal device or stored locally by the terminal device according to the indication information.

[0145] Exemplarily, a digit may be added at the end of the first device fingerprint. 0 indicates that the first device fingerprint is newly generated by the terminal device, and 1 indicates that the first device fingerprint is stored locally by the terminal device.
