Another example is a computer's network card, which is assigned a unique Media Access Control Address (MAC address) during the manufacturing process. However, device fingerprints can be replaced or tampered with during use, making the security of the device fingerprint unreliable.

[0026] In a fifth aspect, an embodiment of the present application provides a device fingerprint generation device, including: a second acquisition module, used to obtain the initial device fingerprint information corresponding to the client and a first generation time; wherein, the first generation time is the time when the target device fingerprint information is generated; a first generation module, used to generate the target device fingerprint information based on the initial device fingerprint information and the first generation time; wherein, the target device fingerprint information includes the initial device fingerprint information and time information spliced ​​with the initial device fingerprint information, and the time information includes the first generation time.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0047] It should be noted that the term "plurality" in the embodiments of the present invention refers to two or more. Therefore, in the embodiments of the present invention, "plurality" can also be understood as "at least two." "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / ," unless otherwise specified, generally indicates an "or" relationship between the associated objects.

[0048] Please refer to FIG. 1 , which is a flow chart of a device fingerprint verification method provided in an embodiment of the present application. The device fingerprint verification method can be applied to a server, wherein the device fingerprint verification method may include the following steps:

[0049] Step S101: Obtain request data sent by the client.

[0050] Step S102: Restore first verification information corresponding to the first generation time according to the target device fingerprint information.

[0051] Step S103: Verify the target device fingerprint information according to the first verification information.

[0052] Specifically, in the above step S101, when the client needs to execute a service, the client may send request data to the server, so that the server can verify the target device fingerprint information of the client based on the above request data.

[0053] The request data may include the target device fingerprint information corresponding to the client. As an embodiment, the target device fingerprint information may include initial device fingerprint information and time information; the target device fingerprint information may be generated by concatenating the initial device fingerprint information and time information.

[0054] The initial device fingerprint information can be generated based on information related to the client. It should be noted that, first of all, the embodiment of the present application does not specifically limit the specific implementation of the above-mentioned information related to the client, and those skilled in the art can make appropriate adjustments according to actual conditions. For example, the information related to the client may include one or more of the following information: the device fingerprint identity document (ID), the time when the above-mentioned device fingerprint ID was first generated, the verifiable information corresponding to the client, the business information corresponding to the client, etc.

[0055] In the embodiments of this application, the device fingerprint ID refers to the device feature or unique device identifier used to uniquely identify the client, and the device fingerprint information refers to the device identifier generated based on the device fingerprint ID and used to identify the target device. The difference between the two is that a client only corresponds to one device fingerprint ID, but can correspond to multiple device fingerprint information.

[0056] The time when the device fingerprint ID is first created can provide some time information during verification to facilitate historical queries, and can also be used for legal time verification; the verifiable information corresponding to the client can include attribute information related to the target device, such as: Android ID, device model and other information; business information can be used to characterize the corresponding business on the client. For example, suppose there are two applications (Application, App), and the same device installs these two Apps with the same device fingerprint ID, but in order to distinguish the two Apps, two different business information can be generated, so that the target device fingerprint information issued by the two APPs is different.

[0057] Secondly, the embodiments of this application do not specifically limit the specific implementation method for generating the initial device fingerprint information. Those skilled in the art may make appropriate adjustments based on actual circumstances. For example, client-related information may be input into a pre-trained neural network model to output the initial device fingerprint information; alternatively, multiple pieces of client-related information may be concatenated to obtain the initial device fingerprint information; alternatively, client-related information may be encrypted to obtain the initial device fingerprint information, etc.

[0058] The time information can be obtained based on the first generation time of the target device fingerprint information. As an embodiment, the time information can include the above-mentioned first generation time; as another embodiment, the above-mentioned first generation time can be processed before obtaining the above-mentioned time information. It is understood that the embodiments of this application do not specifically limit the specific implementation method of the above-mentioned processing of the first generation time, and those skilled in the art can make appropriate adjustments based on actual conditions; for example, the first generation time can be compressed, encrypted, transcoded, etc., or subjected to one or more processing.

[0059] In the above step S102, since the target device fingerprint information includes the initial device fingerprint information and the time information spliced ​​with the initial device fingerprint information, the first verification information corresponding to the first generation time in the target device fingerprint information can be quickly restored.

[0060] As an implementation method, if the time information includes the above-mentioned first generation time, the information at the position corresponding to the first generation time in the target device fingerprint information can be directly extracted to obtain the first verification information; as another implementation method, if the first generation time is processed first, after extracting the information at the position corresponding to the first generation time in the target device fingerprint information, the extracted data can be processed in the opposite way to obtain the first verification information.

[0061] In step S103, the first verification information may be verified to verify the fingerprint information of the target device. In one embodiment, the first verification information may be verified by determining whether the first verification information is the same as the first generation time.

[0062] If the first verification information is different from the first generation time, it indicates that the first verification information verification is abnormal. In this case, it indicates that there is an abnormality in the target device fingerprint information, and subsequent processing can be directly carried out according to the abnormality. For example, if the first generation time is 2023 and the first verification information is 3023, it means that the target device fingerprint information has been tampered with.

[0063] If the first verification time is the same as the first generation time, then the first verification information is verified normally. At this point, as an implementation, it can be assumed that there is no abnormality in the target device fingerprint information; as another implementation, other verification methods can be used to further verify the target device fingerprint information.

[0064] In the above scheme, after obtaining the target device fingerprint information corresponding to the target device, since the above target device fingerprint information includes the initial device fingerprint information and the time information spliced ​​therewith, the first verification information corresponding to the first generation time in the time information can be restored, and the target device fingerprint information can be quickly verified based on the above first verification information, so as to determine whether the target device fingerprint information has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0065] Furthermore, based on the above embodiment, after step S103, the device fingerprint verification method provided in the embodiment of the present application may further include the following steps:

[0066] Step 1): If the first verification information is verified to be normal, the second verification information corresponding to the initial device fingerprint information is restored according to the target device fingerprint information.

[0067] Step 2) Verify the target device fingerprint information based on the second verification information.

[0068] Specifically, in step 1), if the first verification information is verified normally, other verification methods can be used to further verify the target device fingerprint information. As an embodiment, the second verification information corresponding to the initial device fingerprint information can be restored based on the target device fingerprint information.

[0069] It should be noted that the embodiments of this application do not specifically limit the specific implementation method for restoring the initial device fingerprint information. Those skilled in the art may make appropriate adjustments based on the specific implementation method for generating the initial device fingerprint information. For example, the initial device fingerprint information may be split; or the initial fingerprint information may be decrypted; or the initial device fingerprint information may be decoded.

[0070] In the above step 2), the purpose of verifying the target device fingerprint information can be achieved by verifying the above second verification information. It should be noted that the embodiment of the present application does not specifically limit the specific implementation method of verifying the above second verification information, and those skilled in the art can make appropriate adjustments based on the specific implementation method of the initial device fingerprint information. For example, if the initial device fingerprint information is obtained by encryption, it can be determined whether the second verification information can be decrypted normally; or, if the initial device fingerprint information includes a device fingerprint ID, it can be determined whether the second verification information is the same as the device fingerprint ID; or, if the initial device fingerprint information includes business information, it can be determined whether the second verification information is the same as the business information, etc.

[0071] In the above scheme, if the first verification information is verified normally, the target device fingerprint information can be further verified. By restoring the second verification information corresponding to the initial device fingerprint information, the target device fingerprint information can be verified more accurately, thereby determining whether the target device fingerprint information has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0072] Furthermore, based on the above embodiment, the step of verifying the target device fingerprint information according to the second verification information may specifically include the following steps:

[0073] Step 1): decrypt the second verification information.

[0074] Step 2) Determine whether the second verification information is decrypted successfully.

[0075] Specifically, in step 1), if encryption is performed during the generation of the initial device fingerprint information, the second verification information can be decrypted and verified to achieve the purpose of verifying the target device fingerprint information. Therefore, the second verification information can be decrypted.

[0076] In step 2) above, the second verification information can be verified by determining whether the second verification information is successfully decrypted. If the decryption of the second verification information is unsuccessful, it indicates that the second verification information verification is abnormal. In this case, it indicates that there is an abnormality in the fingerprint information of the target device, and subsequent processing can be directly carried out according to the abnormality. For example, if the second verification information cannot be successfully decrypted or a parameter parsing abnormality occurs during the decryption of the second verification information, it indicates that the fingerprint information of the target device has been tampered with.

[0077] If the second verification information is successfully decrypted, it indicates that the second verification information is verified normally. At this point, as an implementation method, it can be considered that there is no abnormality in the target device fingerprint information; as another implementation method, other verification methods can be used to further verify the target device fingerprint information.

[0078] In the above solution, the second verification information can be decrypted to achieve decryption verification of the target device fingerprint information, thereby improving the accuracy of the verification and ensuring the security of the device fingerprint.

[0079] Furthermore, based on the above embodiment, the initial device fingerprint information may further include business information. In this case, after the above step of verifying the target device fingerprint information based on the second verification information, the device fingerprint verification method provided in the embodiment of the present application may further include the following steps:

[0080] If the second verification information is decrypted successfully and the corresponding third verification information is obtained, it is determined whether the service verification information is the same as the service information.

[0081] Specifically, in the above steps, if the second verification information is successfully decrypted, other verification methods can be used to further verify the target device fingerprint information. As an implementation method, if the initial device fingerprint information includes business information, the target device fingerprint information can be verified by performing business verification on the third verification information. Therefore, the business verification information in the decrypted third verification information can be extracted to determine whether the business verification information is the same as the business information.

[0082] The service verification information is the verification information in the third verification information that corresponds to the service information. The service information can be used to represent the corresponding service on the client. If the service verification information is different from the service information, it indicates that the third verification information verification is abnormal. In this case, it indicates that there is an abnormality in the target device fingerprint information, and subsequent processing can be directly carried out according to the abnormality. For example, if the service verification information is different from the service information, it may be that the target device fingerprint information has been replaced.

[0083] If the business verification information is the same as the business information, then the third verification information is verified normally. At this point, as an implementation, it can be considered that there is no abnormality in the target device fingerprint information; as another implementation, other verification methods can be used to further verify the target device fingerprint information.

[0084] In the above scheme, if the second verification information is verified normally, the target device fingerprint information can be further verified by judging whether the business verification information in the decrypted third verification information is the same as the business information, thereby realizing the business verification of the target device fingerprint information, thereby improving the accuracy of the verification and ensuring the security of the device fingerprint.

[0085] Please refer to FIG. 2 , which is a flow chart of a device fingerprint generation method provided in an embodiment of the present application. The device fingerprint generation method can be applied to a server, wherein the device fingerprint generation method may include the following steps:

[0086] Step S201: Obtain initial device fingerprint information and a first generation time corresponding to the client.

[0087] Step S202: Generate target device fingerprint information according to the initial device fingerprint information and the first generation time.

[0088] Specifically, in the above step S201, the initial device fingerprint information can be generated based on information related to the client, and the information related to the client may include one or more of the device fingerprint ID, the time when the above device fingerprint ID is first generated, the verifiable information corresponding to the client, the business information corresponding to the client, and the like.

[0089] The first generation time is the time when the target device fingerprint information is generated. In other words, the first generation time may refer to the time when steps S201 and S202 provided in the embodiments of this application are executed. In one embodiment, the first generation time may be the current time; in another embodiment, the first generation time may be the time when the target device fingerprint information is expected to be generated in the future. For example, the first generation time may include at least one of year, month, day, hour, minute, and second.

[0090] It should be noted that the embodiments of this application do not impose specific limitations on the specific implementation methods for obtaining the initial device fingerprint information and the first generation time, and those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the initial device fingerprint information and the first generation time may be received from an external device; or the initial device fingerprint information and the first generation time may be read from a local or cloud-stored location; or the initial device fingerprint information may be generated in real time.

[0091] In step S202, target device fingerprint information can be generated based on the initial device fingerprint information and the first generation time. The target device fingerprint information includes the initial device fingerprint information and time information concatenated with the initial device fingerprint information, where the time information includes the first generation time. Therefore, the initial device fingerprint information and the time information can be concatenated to obtain the target device fingerprint information.

[0092] In the above scheme, after obtaining the initial device fingerprint information corresponding to the target device and the first generation time corresponding to the target device fingerprint information, the target device fingerprint information can be generated based on the above initial device fingerprint information and the first generation time; based on the above target device fingerprint information, the device fingerprint can be verified to determine whether the device fingerprint has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0093] Furthermore, based on the above embodiment, as an implementation method, the above step S202 may specifically include the following steps:

[0094] The initial device fingerprint information and the first generation time are combined to obtain the target device fingerprint information.

[0095] Specifically, the initial device fingerprint information and the first generation time can be directly concatenated to obtain the target device fingerprint information. The initial device fingerprint information and the first generation time can be concatenated by adding the first generation time to the initial device fingerprint information. For example, if the initial device fingerprint information is abcd and the first generation time is 2001, the target device fingerprint information obtained after concatenation can be abcd2001.

[0096] It should be noted that the embodiments of the present application do not impose any specific restrictions on the specific location where the first generation time is added to the initial device fingerprint information. Those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the first generation time may be added after the initial device fingerprint information (e.g., abcd2001); or, the first generation time may be added before the initial device fingerprint information (e.g., 2001abcd); or, the first generation time may be added within the initial device fingerprint information (e.g., ab2001cd).

[0097] In the above scheme, the initial device fingerprint information and the first generation time can be spliced ​​together, so that the target device fingerprint information can be quickly verified based on the first generation time, thereby determining whether the target device fingerprint information has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0098] Furthermore, based on the above embodiment, as another implementation, the above step S202 may specifically include the following steps:

[0099] Step 1) Encode the first generation time to obtain time information.

[0100] Step 2) Concatenate the initial device fingerprint information and time information to obtain the target device fingerprint information.

[0101] Specifically, in the above step 1), the first generation time may be encoded to obtain time information, and then the initial device fingerprint information and the time information may be concatenated to obtain the target device fingerprint information.

[0102] It should be noted that the embodiment of the present application does not specifically limit the specific implementation method of encoding the first generation time. Those skilled in the art can make appropriate adjustments based on actual conditions. For example, the first generation time can be compressed or Huffman encoded.

[0103] Taking the base-58 compression of the first generation time as an example, assuming that the first generation time is 20231030, the base-58 compression can be used to obtain the compressed time information 2MFYS.

[0104] In the above step 2), the compressed time information can be spliced ​​with the initial device fingerprint information; it can be understood that the specific implementation method of splicing the time information and the initial device fingerprint information is similar to the specific implementation method of splicing the first generated time and the initial device fingerprint information, and will not be repeated here.

[0105] In the above solution, the first generation time may be encoded first, and then the initial fingerprint information and the encoded time information may be concatenated, thereby reducing the data volume of the target device fingerprint information while achieving fast verification.

[0106] Furthermore, based on the above embodiment, the above step S201 may specifically include the following steps:

[0107] Step 1) Obtain the device fingerprint ID and device feature information corresponding to the client.

[0108] Step 2) Generate initial device fingerprint information based on the device fingerprint ID and device feature information.

[0109] Specifically, in step 1) above, the device fingerprint ID corresponding to the client can be generated only once and then stored locally or in the cloud; while the device characteristic information corresponding to the client can be obtained and stored synchronously at the same time as the device fingerprint ID is generated, or the device information can be queried in real time. The device characteristic information may include at least one of the second generation time of the first generation of the device fingerprint ID, the verifiable information corresponding to the client, and the business information corresponding to the client.

[0110] It should be noted that, first, the embodiments of this application do not specifically limit the specific implementation method for obtaining the device fingerprint ID corresponding to the client, and those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the device fingerprint ID may be received from an external device; or the device fingerprint ID may be read from a local or cloud-stored device; or the device fingerprint ID may be generated for the first time based on the device parameters reported by the client.

[0111] Secondly, the embodiments of this application do not specifically limit the specific implementation methods for obtaining device feature information corresponding to the client. Those skilled in the art may make appropriate adjustments based on actual circumstances. For example, device feature information sent by an external device may be received; device feature information stored locally or in the cloud may be read; or device feature information may be queried in real time.

[0112] It is understandable that the method of obtaining the device fingerprint ID corresponding to the client and the method of obtaining the device feature information corresponding to the client may be the same or different.

[0113] In step 2) above, the present embodiment does not specifically limit the specific implementation method for generating the initial device fingerprint information based on the device fingerprint ID and device feature information. Those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the device fingerprint ID and device feature information may be concatenated to obtain the initial device fingerprint information; or the device fingerprint ID and device feature information may be encrypted to obtain the initial device fingerprint information; or the device fingerprint ID and device feature information may be encoded to obtain the initial device fingerprint information, etc.

[0114] In the above solution, the initial device fingerprint information can include the device fingerprint ID and device feature information, so that it can adapt to more usage scenarios and perform different verifications on the target device fingerprint information based on different scenarios, thereby reducing the risk of the device fingerprint ID being replaced or tampered with, and ensuring the security of the device fingerprint.

[0115] Furthermore, based on the above embodiment, the step of generating initial device fingerprint information based on the device fingerprint ID and device feature information may specifically include the following steps:

[0116] Step 1) Concatenate the device fingerprint ID and device feature information to obtain first device fingerprint information.

[0117] Step 2): Encrypt the first device fingerprint information to obtain the second device fingerprint information.

[0118] Step 3) Perform character transcoding on the second device fingerprint information to obtain initial device fingerprint information.

[0119] Specifically, in the above step 1), the device fingerprint ID and the device feature information may be concatenated to obtain the first device fingerprint information.

[0120] Among them, the method of splicing the device fingerprint ID and the device feature information can be: adding the device feature information to the device fingerprint ID, for example: assuming that the device fingerprint ID is efg, the device feature information can include A, B, and C, then the first device fingerprint information obtained after splicing can be efgABC.

[0121] It should be noted that the embodiments of this application do not impose any specific restrictions on the specific location where the device feature information is added to the device fingerprint ID. Those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the device feature information may be added after the device fingerprint ID (e.g., efgABC); or, the device feature information may be added before the device fingerprint ID (e.g., ABCefg); or, the device feature information may be added within the device fingerprint ID (e.g., eABfCg).

[0122] In the above step 2), the first device fingerprint information obtained by splicing in the above step 1) may be encrypted, thereby obtaining the second device fingerprint information.

[0123] It should be noted that the embodiments of this application do not specifically limit the specific implementation method for encrypting the first device fingerprint information, and those skilled in the art may make appropriate adjustments based on actual circumstances. For example, one or more encryption algorithms such as a symmetric encryption algorithm, an asymmetric encryption algorithm, and a hash algorithm may be used to encrypt the first device fingerprint information.

[0124] In the above step 3), the second device fingerprint information encrypted in the above step 2) may be character-transcoded, thereby obtaining the initial device fingerprint information.

[0125] It should be noted that the embodiments of this application do not specifically limit the specific implementation method for transcoding the second device fingerprint information, and those skilled in the art may make appropriate adjustments based on actual circumstances. For example, the second device fingerprint information may be transcoded using one or more of the following character transcoding methods: ASCII encoding, BASE64, BASE62, etc.

[0126] In the above solution, after concatenating the device fingerprint ID and the device feature information, the concatenated first device fingerprint information can be encrypted and character transcoded, thereby further reducing the risk of the device fingerprint being replaced or tampered with, and ensuring the security of the device fingerprint.

[0127] Furthermore, based on the above embodiment, the step of performing character transcoding on the second device fingerprint information to obtain the initial device fingerprint information may specifically include the following steps:

[0128] The second device fingerprint information is character-transcoded using a preset transcoding method to obtain initial device fingerprint information; wherein the initial device fingerprint information does not include special characters.

[0129] Specifically, as an implementation method, the special characters may include one or more of symbols such as "+", " / ", "=", etc.; as another implementation method, in the above-mentioned preset transcoding method, the second device fingerprint information may be character-transcoded using BASE62 that removes special characters, thereby obtaining initial device fingerprint information that does not include special characters.

[0130] In the above scheme, the second device fingerprint information can be character-transcoded using a preset transcoding method to obtain initial device fingerprint information that does not include special characters. Since the device fingerprint will be used as a parameter of the request, special characters pose risks during transmission. Therefore, the above transcoding method can reduce the above risks and thus ensure the security of the device fingerprint.

[0131] Please refer to FIG3 , which is a flowchart of another device fingerprint verification method provided by an embodiment of the present application. The device fingerprint verification method can be applied to a server, wherein the device fingerprint verification method may include the following steps:

[0132] Step S301: Obtain initial device fingerprint information and a first generation time corresponding to the client.

[0133] Step S302: Generate target device fingerprint information according to the initial device fingerprint information and the first generation time.

[0134] Step S303: Obtain the request data sent by the client.

[0135] Step S304: Restore first verification information corresponding to the first generation time according to the target device fingerprint information.

[0136] Step S305: Verify the target device fingerprint information according to the first verification information.

[0137] Specifically, in the above step S301, the initial device fingerprint information can be generated based on information related to the client, and the information related to the client may include one or more of the device fingerprint ID, the time when the above device fingerprint ID is first generated, the verifiable information corresponding to the client, the business information corresponding to the client, and the like.

[0138] The first generation time is the time when the target device fingerprint information is generated. In other words, the first generation time may refer to the time when steps S301 and S302 provided in the embodiment of this application are executed. In one embodiment, the first generation time may be the current time; in another embodiment, the first generation time may be the time when the target device fingerprint information is expected to be generated in the future. For example, the first generation time may include at least one of year, month, day, hour, minute, and second.

[0139] In step S302, target device fingerprint information can be generated based on the initial device fingerprint information and the first generation time. The target device fingerprint information includes the initial device fingerprint information and time information concatenated with the initial device fingerprint information, where the time information includes the first generation time. Therefore, the initial device fingerprint information and the time information can be concatenated to obtain the target device fingerprint information.

[0140] In step S303, when the client needs to perform a service, the client may send request data to the server so that the server can verify the target device fingerprint information of the client based on the request data. The request data may include the target device fingerprint information corresponding to the client.

[0141] In the above step S304, since the target device fingerprint information includes the initial device fingerprint information and the time information spliced ​​with the initial device fingerprint information, the first verification information corresponding to the first generation time in the target device fingerprint information can be quickly restored.

[0142] As an implementation method, if the time information includes the above-mentioned first generation time, the information at the position corresponding to the first generation time in the target device fingerprint information can be directly extracted to obtain the first verification information; as another implementation method, if the first generation time is processed first, after extracting the information at the position corresponding to the first generation time in the target device fingerprint information, the extracted data can be processed in the opposite way to obtain the first verification information.

[0143] In step S305, the first verification information may be verified to verify the target device fingerprint information. In one embodiment, the first verification information may be verified by determining whether the first verification information is the same as the first generation time.

[0144] If the first verification information differs from the first generation time, this indicates a verification anomaly. This indicates an anomaly in the target device's fingerprint information, and subsequent processing can be performed based on the anomaly. For example, if the first generation time is 2023 and the first verification information is 3023, this indicates that the target device's fingerprint information has been tampered with.

[0145] If the first verification time is the same as the first generation time, then the first verification information is verified normally. At this point, as an implementation, it can be assumed that there is no abnormality in the target device fingerprint information. As another implementation, other verification methods can be used to further verify the target device fingerprint information.

[0146] In the above scheme, after obtaining the initial device fingerprint information corresponding to the target device and the first generation time corresponding to the target device fingerprint information, the target device fingerprint information can be generated based on the above initial device fingerprint information and the first generation time; based on the above target device fingerprint information, the device fingerprint can be quickly verified to determine whether the device fingerprint has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0147] In summary, the above-mentioned device fingerprint verification method and device fingerprint generation method can both be executed on the server. After generating the target device fingerprint information, the server can send the target device fingerprint information to the client. After receiving the target device fingerprint information, the client can store the target device fingerprint information. When the client needs to make a data request, it can carry the target device fingerprint information. Correspondingly, after receiving the data request from the client, the server can verify the target device fingerprint information carried in the data request.

[0149] In the above scheme, after obtaining the target device fingerprint information corresponding to the target device, since the above target device fingerprint information includes the initial device fingerprint information and the time information spliced ​​therewith, the first verification information corresponding to the first generation time in the time information can be restored, and the target device fingerprint information can be quickly verified based on the above first verification information, so as to determine whether the target device fingerprint information has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0155] In the above scheme, if the second verification information is verified normally, the target device fingerprint information can be further verified by judging whether the business verification information in the decrypted third verification information is the same as the business information, thereby realizing the business verification of the target device fingerprint information, thereby improving the accuracy of the verification and ensuring the security of the device fingerprint.

[0159] In the above scheme, the initial device fingerprint information and the first generation time can be spliced ​​together, so that the target device fingerprint information can be quickly verified based on the first generation time, thereby determining whether the target device fingerprint information has been replaced or tampered with during use, thereby ensuring the security of the device fingerprint.

[0160] In an optional implementation, the first generation module 502 is specifically configured to: encode the first generation time to obtain the time information; and concatenate the initial device fingerprint information and the time information to obtain the target device fingerprint information.

[0167] In the above scheme, the second device fingerprint information can be character-transcoded using a preset transcoding method to obtain initial device fingerprint information that does not include special characters. Since the device fingerprint will be used as a parameter of the request, special characters pose risks during transmission. Therefore, the above transcoding method can reduce the above risks and thus ensure the security of the device fingerprint.
