In order to solve the problems in the related art, an embodiment of the present application provides a method for processing a device fingerprint, which relates to a live broadcast client and a wind control server, where the live broadcast client acquires device information thereof using an acquisition script, and then acquires a second device fingerprint, where the second device fingerprint is generated from a first device fingerprint and a check code, the first device fingerprint is generated according to the device information, the check code is generated according to a preset algorithm, and finally the second device fingerprint and the device information are sent to the wind control server; and the wind control server acquires the first equipment fingerprint from the second equipment fingerprint by using an inverse algorithm of the preset algorithm, acquires a third equipment fingerprint, generates the third equipment fingerprint according to the equipment information, and determines that the second equipment fingerprint is valid under the condition that the first equipment fingerprint is the same as the third equipment fingerprint.

In some exemplary application scenarios, statistical data analysis may be performed from the dimension of the hardware device of the user based on the device fingerprint, such as statistics of daily activity (number of active users), page browsing amount, user effective click amount, or user retention of the APP.

In other exemplary application scenarios, in the live broadcast field, there are behaviors related to internet financial activities such as live broadcast shopping, virtual gift purchase, red envelope robbing, etc., the core of the internet financial activities lies in risk control, and the basic problems to be solved by wind control are: "who you are? Where do you come from? What are you going to do? The unique identity confirmation is difficult to carry out in the online transaction, so that the equipment fingerprint can be used for assisting judgment to confirm and analyze various behaviors in the online transaction process, thereby effectively preventing the problems of garbage registration, library collision prevention, wool pulling prevention, single reverse swiping, accurate marketing, payment anti-fraud, credit-giving anti-fraud, user portrait analysis, complex relationship network and the like.

In some embodiments, referring to fig. 1, fig. 1 illustrates a schematic structural diagram of a live wind control system, where the live wind control system includes a wind control server 20 and a live client 10. The live broadcast user terminal 10 may be a main broadcast terminal in a live broadcast scene, or may be a viewer terminal in the live broadcast scene, which is not limited in this embodiment.

The live broadcast user terminal 10 collects the own equipment information by using the collection script; acquiring a second device fingerprint, wherein the second device fingerprint is generated by a first device fingerprint and a check code, the first device fingerprint is generated according to the device information, and the check code is generated according to a preset algorithm; and sending the second device fingerprint and the device information to the wind control server 20.

The wind control server 20 obtains the first device fingerprint from the second device fingerprint by using an inverse algorithm of the preset algorithm; acquiring a third device fingerprint, wherein the third device fingerprint is generated according to the device information; determining that the second device fingerprint is valid if the first device fingerprint and the third device fingerprint are the same.

In some embodiments, a device fingerprint processing component may be loaded in the live client 10, so that the live client 10 may execute the process related to the device fingerprint mentioned in this embodiment through the device fingerprint processing component, where the device fingerprint processing component is configured to actively send an acquisition request to the wind control server 20 after detecting a specified operation (such as entering a specified page or triggering a specified control) of the live client 10.

In an example, the device fingerprint processing component may be generated in an SDK manner, and an SDK may be implanted in the live broadcast user terminal 10 to be embedded in a required service scene, where the service scene may be a scene in which the live broadcast user terminal 10 enters a specified page or a scene in which the live broadcast user terminal 10 triggers a specified control; in one example, the designated page can be, for example, a login page, a payment page, a coupon pickup page, a red envelope distribution page, or the like, and the designated control can be, for example, a payment control, a login control, a coupon pickup control, or the like.

Then, under the condition that it is detected that the live broadcast user end 10 enters a specified page or a specified control is triggered, the live broadcast user end 10 may actively send a collection request to the wind control server 20, so that the wind control server 20 may respond to the collection request and return the collection script to the live broadcast user end 10, and then the live broadcast user end 10 uses the collection script to collect the own device information after receiving the collection script. The device information includes, but is not limited to, system environment information, hardware information, sensor information, a system ID or a MAC address, etc. For example, the live client 10 may delete the capture script after capturing the device information using the capture script. In this embodiment, the acquisition script is stored in the wind control server 20, and is not locally stored at the live broadcast client 10, and the live broadcast client 10 needs to acquire the device information based on the acquisition script issued by the wind control server 20 at each time, so that the acquisition script can be effectively prevented from being statically analyzed reversely, a third-party device cannot know specific content of the acquired device information, and the security and stability of the generated device fingerprint can be ensured.

In order to further improve the security of the device fingerprint, the live broadcast user terminal 10 and the wind control server 20 can predetermine in advance the key pair that can carry out encryption and decryption, the wind control server 20 can respond to after receiving the acquisition request uses the public key pair the acquisition script is encrypted, and sends the acquisition script after encrypting to the live broadcast user terminal 10, then the live broadcast user terminal 10 can use the private key to decrypt the acquisition script after encrypting, and uses the acquisition script after decrypting to collect the device information.

Of course, considering that the live broadcast client 10 may not receive the acquisition script sent by the wind control server 20 after sending the acquisition request due to a network fault, a network congestion or a wind control server fault, in this case, it may be preset that the device fingerprint processing component carries the acquisition script, and in the case that the acquisition script sent by the wind control server 20 is not received within a preset time period, the acquisition script carried by the device fingerprint processing component may be used to acquire the device information, thereby ensuring that the device information can be normally and effectively acquired. In some embodiments, the device information that can be collected by different operating systems may vary, taking into account the different open permissions of the different operating systems. Therefore, the collection script may include sub-collection scripts for different operating systems, and the device information collected by the sub-collection scripts corresponding to the different operating systems is different. It can be understood that the device information collected by the sub-collection scripts corresponding to different operating systems is data that can be collected within the open authority permitted by the operating systems. The live broadcast client 10 may select a target sub-collection script from the collection scripts according to its own operating system, and then collect the device information using the target sub-collection script. The embodiment acquires the corresponding device information according to different operating systems, and is beneficial to ensuring that the device fingerprints capable of playing a role of unique identification can be generated on different devices and carriers.

For example, the acquisition script further carries mapping relationships between different operating systems and sub acquisition scripts, so that the live broadcast client 10 may select a target sub acquisition script from the acquisition scripts according to its own operating system and the mapping relationships.

In some embodiments, in order to save operating resources of the live user side 10, the live user side 10 may store the second device fingerprint in the local storage space after first generating the second device fingerprint, so that the second device fingerprint may be reused without being regenerated. The live broadcast user end 10 may detect whether the second device fingerprint is stored in a local storage space after acquiring the device information by using the issued acquisition script each time, and under the condition that the second device fingerprint is stored in the local storage space, the live broadcast user end 10 may acquire the second device fingerprint from the local storage space, and directly send the second device fingerprint and the device information acquired by using the acquisition script this time to the wind control server 20 without generating the second device fingerprint again, which is beneficial to saving the running resources of the live broadcast user end 10; and in the case that the local storage space does not store the second device fingerprint, after the live broadcast user end 10 collects the device information, the live broadcast user end may generate a first device fingerprint according to the device information, then generate a check code by using a preset algorithm, fuse the first device fingerprint and the check code to generate a second device fingerprint, and then send the second device fingerprint and the device information to the wind control server 20.

For example, in a case that the local storage space does not store the second device fingerprint, after the live client 10 collects the device information, the device information may be processed by using a preset encryption algorithm to obtain the first device fingerprint, where the preset encryption algorithm includes, but is not limited to, a DES encryption algorithm, an MD5 algorithm, and the like; and then generating a check code by using a preset algorithm, and fusing the first equipment fingerprint and the check code to generate a second equipment fingerprint.

For example, a check code may be generated in a variety of ways and fused with the first device fingerprint to generate the second device fingerprint.

In some possible implementations, the live client 10 may process the first device fingerprint to generate a check code; if the first device fingerprint is subjected to hash operation, a first character string is obtained, then characters at least one appointed position in the first character string are extracted to obtain a check code, and then the check code and the first device fingerprint are spliced to obtain the second device fingerprint; for another example, the first device fingerprint is encoded (e.g., dictionary encoding, interval encoding, and the like) to obtain a check code, and the check code is inserted into a designated position in the first device information to obtain a second device fingerprint.

In some possible implementations, the live client 10 may process the attribute information of the first device fingerprint to generate a check code; the attribute information includes, but is not limited to, a length value (or a data size) and a generation time of the first device information, and the length value is taken as an example: if the length value of the first device information can be negated, a check code is obtained, and the check code is inserted into a specified position in the first device fingerprint to generate a second device fingerprint; if the length value of the first device information is encoded to obtain a check code, the check code and the first device information are spliced to obtain a second device fingerprint.

In some possible implementations, to further improve the confidentiality and security of the second device fingerprint, the live user terminal 10 may further synthesize the first device fingerprint and its attribute information to generate the check code. In an example, when generating a second device fingerprint, the live broadcast user terminal 10 performs a hash operation on the first device fingerprint to obtain a first character string, and then extracts a character in at least one specified position in the first character string to obtain a first password string; the at least one designated location may be specifically set according to an actual application scenario, for example, bits 1, 8, 16, and 24 in the first string are extracted and then spliced into the first password string. Then, the live broadcast user side 10 processes the first character string to obtain a subscript character, encodes the subscript character by using a preset password dictionary to obtain an encoded character, and splices the encoded character and the first password string to obtain a second password string; the preset password dictionary may be set according to an actual application scenario, and this embodiment does not limit this, for example, the preset password dictionary is "mzrypbqxtwkfuacsvgldjhnio". Then, the live broadcast user end 10 performs a modulo multi-round switching process on the first character string to obtain a first flag character, and inserts the first flag character into the first device fingerprint according to the position indicated by the subscript character; then, a length value of the device information is obtained, and a second zone character is generated according to the length value and the first zone character, for example, the length value and the first zone character are subjected to xor operation to generate the second zone character; finally, the second password string, the first zone bit character, the second zone bit character, the length value after the negation and the first equipment fingerprint inserted with the first zone bit character are spliced to obtain a second character string; and encrypting the second character string to generate the second device fingerprint. In this embodiment, generating the second device fingerprint in the above manner is beneficial to improving the security and safety of the second device fingerprint, so that the second device fingerprint is difficult to be illegally tampered in the transmission process.

In this embodiment, the splicing sequence of the second password string, the first flag character, the second flag character, the inverted length value, and the first device fingerprint into which the first flag character is inserted is not limited in any way, and may be specifically set according to an actual application scenario, for example, the splicing sequence of "the second password string → the first flag character → the second flag character → the first device fingerprint into which the first flag character is inserted → the inverted length value" is performed to obtain the second character string, and then the second character string may be encrypted by using a preset encryption algorithm, such as a DES encryption algorithm, to generate the second device fingerprint.

Further, the second device fingerprint may be processed into a visible string using a preset visibility algorithm, such as a base64 algorithm, so as to facilitate viewing and transmission.

Under the condition that the local storage space does not store the second device fingerprint, after the live broadcast client 10 generates the second device fingerprint, the live broadcast client stores the second device fingerprint in the current storage space, and sends the generated second device fingerprint and the device information acquired by using the acquisition script to the wind control server 20. Under the condition that the local storage space stores the second device fingerprint, the live broadcast user side 10 acquires the second device fingerprint from the local storage space, and sends the acquired second device fingerprint and the device information acquired by using the acquisition script to the wind control server 20.

In some embodiments, for a scenario in which the wind control server 20 issues the acquisition script, it is considered that there may be behaviors such as virtual execution that affect the security of the device fingerprint, for example, after a certain live user terminal 10 acquires device information using the acquisition script issued at the current time, the device information is illegally acquired by a third-party user, and after the third-party user receives the acquisition script, the third-party user does not execute the acquisition script but sends the illegally acquired device information to the wind control server 20, which causes a security risk problem in the device fingerprint generation or verification process. Based on this, the acquisition script issued by the wind control server 20 further carries a verification instruction, the verification instruction is randomly acquired from a first database by the wind control server 20, the first database stores a plurality of different verification instructions, after receiving the acquisition script, the live broadcast user terminal 10 further executes the verification instruction to obtain a verification result, and synchronously sends the verification result, the second device fingerprint and the device information to the wind control server 20; the wind control server 20 may determine whether the device information is acquired based on the collection script issued this time according to the verification result, so as to effectively determine whether the collection script is virtually executed, and thus protect the security and stability of the device fingerprint in all directions.

As an example, the first database may store the plurality of different verification instructions and verification results thereof, after receiving the verification result, the second device fingerprint, and the device information, the wind control server 20 may compare the verification result sent by the live broadcast user terminal 10 with the verification result of the verification instruction stored in the first database, if the comparison is consistent, it is determined that the device information is acquired based on the collection script issued this time, and if the comparison is inconsistent, it is determined that the device information does not meet the requirement, the second device fingerprint and the device information sent by the live broadcast user terminal 10 this time are discarded, further, the collection script may be issued to the live broadcast user terminal 10 again, thereby facilitating improvement of security of a device fingerprint generation or verification process.

It can be understood that, in this embodiment, the verification instruction is not limited at all, and may be specifically set according to an actual application scenario, for example, the verification instruction may be a mathematical operation problem, and for example, the verification instruction may be an object that meets requirements and is selected from a plurality of objects (such as pictures, characters, or characters).

In some embodiments, after receiving the verification result, the second device fingerprint, and the device information, and determining, based on the verification result, that the device information is acquired based on the acquisition script issued this time, the wind control server may acquire, by using an inverse algorithm of the preset algorithm, the first device fingerprint from the second device fingerprint, and then acquire a third device fingerprint, where the third device fingerprint is generated according to the device information, compare the first device fingerprint with the third device fingerprint, and if the first device fingerprint is the same as the third device fingerprint, determine that the second device fingerprint is valid; wherein the third device fingerprint and device information used to generate the third device fingerprint may be stored in a second database. In this embodiment, the wind control server 20 may verify whether the second device fingerprint is tampered with according to the third device fingerprint, and may effectively identify the swipe registration, the library collision, the swipe of the black, grey and wool parties, the fraud, and the like, thereby being beneficial to ensuring the security and the stability of the generated device fingerprint.

Under the condition that the local storage space of the live broadcast user end 10 stores the second device fingerprint and the wind control server 20 stores the third device fingerprint correspondingly, there may be some special situations that cause the storage space of the live broadcast user end 10 to be refreshed, the second device fingerprint stored in the local storage space of the live broadcast user end 10 is deleted, the live broadcast user end 10 regenerates the second device fingerprint, but the wind control server 20 already has the corresponding third device fingerprint. For example, the system or version of the live broadcast client 10 is updated, or the APP related to the second device fingerprint is uninstalled and then reinstalled, and the second device fingerprint stored in the local storage space of the live broadcast client 10 is deleted, that is, the local storage space of the live broadcast client 10 does not store the second device fingerprint, so that the live broadcast client 10 collects device information based on the currently issued collection script and regenerates the second device fingerprint.

In order to be compatible with the above situation, after receiving the second device fingerprint and the device information, the wind control server compares the device information sent by the live broadcast user terminal 10 with the device information stored in the second database, and determines the similarity between the two devices; in an example, the device information sent by the live broadcast user terminal 10 may be compared with all the device information stored in the second database one by one, and the similarity between the two devices is determined; in another example, considering that the amount of data stored in the second database is increasing with time, in order to save the calculation resources of the wind control server 20, the device information sent by the live client 10 may be compared with the device information stored in the second database in a preset time period one by one, and the similarity between the two devices may be determined.

In some embodiments, if the similarity is greater than a preset threshold, it indicates that the live broadcast user terminal 10 does not generate a second device fingerprint for the first time, and a corresponding third device fingerprint is already stored in the wind control server 20, the wind control server 20 obtains a third device fingerprint corresponding to the device information in the second database, obtains the first device fingerprint from the second device fingerprint by using an inverse algorithm of the preset algorithm, and compares the first device fingerprint with the third device fingerprint, and if the first device fingerprint is the same as the third device fingerprint, it determines that the second device fingerprint is valid; if the first device fingerprint and the third device fingerprint are different, it indicates that the live broadcast user end 10 may have a small amount of information changed due to a system or version update, and the like, in the re-collected device information, so that a new second device fingerprint is generated, in order to uniquely identify the same live broadcast user end, the wind control server 20 may send the third device fingerprint corresponding to the device information in the second database to the live broadcast user end 10, after receiving the third device fingerprint, the live broadcast user end 10 generates a check code using a preset algorithm and inserts the check code into the third device fingerprint, generates the second device fingerprint, and then replaces the original second device fingerprint with the generated second device fingerprint. In this embodiment, based on the above comparison method, even if a small amount of device information is changed due to a system update or version update of the live broadcast user terminal 10, the same device fingerprint may be used to ensure the unique identifier of the live broadcast user terminal 10, which is beneficial to improving the stability of the device fingerprint.

In addition, in consideration of the security problem during the transmission process, under the condition that the similarity is greater than the preset threshold and the first device fingerprint and the third device fingerprint are different, the wind control server 20 may also generate a check code by using a preset algorithm after acquiring the third device fingerprint corresponding to the device information in the second database, insert the check code into the third device fingerprint, generate a second device fingerprint, and send the second device fingerprint to the live broadcast client 10, where the live broadcast client 10 replaces the original second device fingerprint with the second device fingerprint sent by the wind control server 20. In this embodiment, the second device fingerprint is transmitted instead of directly transmitting the third device fingerprint, which effectively prevents the risk of tampering the device fingerprint, thereby facilitating the security and stability of the generated device fingerprint.

In other embodiments, if the similarity is less than or equal to a preset threshold, it indicates that the live broadcast user end 10 generates a second device fingerprint for the first time, and a corresponding third device fingerprint is not stored in the wind control server 20, the wind control server 20 generates a third device fingerprint according to the device information sent by the live broadcast user end 10, and obtains the first device fingerprint from the second device fingerprint by using an inverse algorithm of the preset algorithm; and comparing the third device fingerprint with the first device fingerprint, and if the first device fingerprint is the same as the third device fingerprint, determining that the second device fingerprint is valid, and storing the third device fingerprint and corresponding device information in a second database.

It can be understood that the preset threshold corresponding to the similarity may be specifically set according to an actual application scenario, which is not limited in this embodiment, for example, the preset threshold is set to be sufficient to distinguish device fingerprints between different live broadcast user terminals.

In some embodiments, the third device fingerprint is further associated with a trustworthiness score of the live user terminal 10; as mentioned above, when the similarity is less than or equal to the preset threshold, the wind control server 20 generates a third device fingerprint according to the device information sent by the live broadcast user terminal 10, and the generated third device fingerprint is not associated with the confidence score of the live broadcast user terminal 10, so that the preset confidence score of the live broadcast user terminal 10 is associated with the third device fingerprint under the condition that the third device fingerprint is determined to be stored. For example, in a case where a third device fingerprint is generated for the first time, the reliability of the live broadcast user end 10 corresponding to the third device fingerprint cannot be evaluated yet, so an initial reliability score may be preset for the live broadcast user end 10, for example, the same initial reliability score may be preset for all the live broadcast user ends 10.

When the similarity is greater than the preset threshold, the wind control server 20 already stores a corresponding third device fingerprint, and the third device fingerprint is associated with the credibility score of the live broadcast user terminal 10, so that the wind control server 20 may adjust the credibility score of the live broadcast user terminal 10 associated with the third device fingerprint according to the similarity. In this embodiment, by associating the credibility scores of the live broadcast user terminals 10, it is helpful to effectively evaluate the variation degree of the device information of the live broadcast user terminals 10, and thus, the security evaluation of the live broadcast user terminals 10 is realized.

Illustratively, in the process of adjusting the credibility score of the live broadcast user terminal 10 associated with the third device fingerprint according to the similarity, the similarity and the reduction of the credibility score form a negative correlation relationship, the greater the similarity, the smaller the reduction of the credibility score, the smaller the similarity, and the greater the reduction of the credibility score; in an example, for example, the feasibility score of the live broadcast user terminal 10 is 90 points, if the similarity is 100%, the reduction of the credibility score is 0, that is, the credibility score is unchanged, and is still 90 points; if the similarity is 80%, the reduction amplitude of the credibility score is 5, namely the adjusted credibility score is 85 (90-5).
