It should be understood that the specific embodiments described herein are intended to be illustrative of the application and are not intended to be limiting.

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
The unique identifiers of the electronic devices in the existing market are various, because the device manufacturers are more, the identifier generation rules of different device manufacturers are different, the system application versions are various, and the information security related policy is limited, for example, the unique fingerprint identifiers of the general devices such as imei, mac, serialno, androidid, oaid cannot be obtained to cover all the devices, so that the unique identifiers can only be generated by the mode of combining the fingerprint identifiers ID (identity) of the mobile terminal data in most of the enterprises in the prior art, the global uniqueness of the device identifiers cannot be ensured, the unique fingerprint identifiers of the general devices are easily directly modified by software, and the problem of device identifier collision is also easy to exist.
In order to solve the problems in the prior art, the embodiment of the application provides a method, a device, equipment and a computer storage medium for generating equipment identifiers. The method for generating the device identifier provided in the embodiment of the present application is first described below.
Fig. 1 shows a flowchart of a method for generating a device identifier according to an embodiment of the present application. As shown in fig. 1, the method specifically includes the following steps:
s101, under the condition that a system application installed on an electronic device is started, the electronic device respectively acquires first device parameter information of the electronic device from a local cache of the electronic device and acquires second device parameter information of the electronic device from a server, wherein the first device parameter information and the second device parameter information at least comprise kernel user identifiers corresponding to the system application in the electronic device;
s102, under the condition that the first equipment parameter information does not comprise the equipment unique identifier of the electronic equipment, the electronic equipment sends a query request carrying second equipment parameter information to a server;
s103, the server side inquires whether a device identifier matched with a kernel user identifier corresponding to the system application in the second device parameter information exists in a database of the server side according to the inquiry request;
S104, returning the device identifier which is inquired from the server-side database and is matched with the kernel user identifier corresponding to the system application in the second device parameter information to the electronic device under the condition that the device identifier which is matched with the kernel user identifier corresponding to the system application in the second device parameter information exists in the server-side database;
s105, under the condition that the device identifier matched with the kernel user identifier corresponding to the system application in the second device parameter information does not exist in the server database, generating the device identifier matched with the kernel user identifier corresponding to the system application in the second device parameter information according to the kernel user identifier corresponding to the system application in the second device parameter information;
s106, the device identification which is generated by the server and is matched with the kernel user identification corresponding to the system application in the second device parameter information is associated and stored in a server database.
Thus, according to the method for generating the device identifier in the embodiment of the application, under the condition that the system application installed on the electronic device is started, the first device parameter information of the electronic device is obtained from the local cache of the electronic device, the second device parameter information of the electronic device is obtained from the server, and under the condition that the first device parameter information does not include the unique device identifier, a query request carrying the second device parameter information is sent to the server, so that the server generates the device identifier matched with the kernel user identifier corresponding to the system application in the second device parameter information according to the kernel user identifier corresponding to the system application in the second device parameter information under the condition that the server does not have the device identifier matched with the second device parameter information in the database. Because each electronic device comprises a plurality of system applications, according to the generation rule of the kernel user identification, the kernel user identification corresponding to each system application is unique. Therefore, the device identification is generated in a mode of no longer relying on fingerprint identification combination, but the device unique identification is generated based on the kernel user identification corresponding to the system application, so that the global uniqueness of the device unique identification is ensured.
In some embodiments, in S101, first device parameter information of the electronic device is obtained from a local cache of the electronic device, and second device parameter information of the electronic device is obtained from a server through a system call interface API. The first device parameter information and the second device parameter information may include a device vendor, a device model, a system application package name, and a kernel user identifier (User Identification, UID) of the electronic device, where the system application package name refers to a unique identifier of a system application program on the electronic device, and the kernel user identifier UID refers to a kernel user ID allocated by an operating system of the electronic device for each system application.
In some embodiments, in S102, the first device parameter information obtained from the local cache may or may not include a device unique identifier of the electronic device. As an example, in the case that the first device parameter information does not include the device unique identifier of the electronic device, the electronic device needs to send a query request carrying the second device parameter information to the server, so that the server queries, according to the query request, whether the device identifier matched with the kernel user identifier corresponding to the system application in the second device parameter information exists in the database of the server.
The electronic device may upload the second device parameter information "device vendor+device model+system application package name+kernel user identifier" of the electronic device currently acquired from the server to the server through the interface "receive query device unique identifier request" of the server in a query request manner.
In some embodiments, in S103, after receiving the query request sent by the electronic device, the server queries, according to the second device parameter information carried in the query request, whether a device identifier matched with the kernel user identifier corresponding to the system application in the second device parameter information exists in the server database.
As an example, if the same number of kernel user identifiers corresponding to the system applications in the second device parameter information exists in the query server database, the number of device identifiers is greater than a preset number, and the preset number may be set to 95% of the number of the electronic device system applications. After the electronic equipment leaves the factory for the first time, the system service scans all system application installation packages, generates a UID for each system application, scans a system catalog file and generates the UID in an incremental mode. However, on different electronic devices, each link in the system application, the scanning environment, the execution time and the increment time has a difference and a variable, and the UIDs generated for the same system application on different devices of the same model are different due to the generation mode.
For example, if m identical applications exist in the system application list of two electronic devices of the same manufacturer and the same model, m different kernel user identifications exist correspondingly, and the number of kernel user identification permutation and combination is a factorial of m, as shown in the following formula (1), the probability P that the kernel user identifications are identical is extracted from the factorial of m:
where P represents the probability that the kernel user identity is the same extracted from the factorization of m,
representing the number of kernel user identification permutations and combinations.
According to the above formula (1), a system schematic of the probability P that the number m of system applications is the same as the kernel user identifier is obtained as shown in the following table 1:
table 1 System application number and kernel user identification same probability relation schematic table
As can be seen from Table 1, when the number of system applications m is greater than or equal to 10, the probability of extracting the same kernel user identifier from the factorization of m is extremely small, and by statistics, the average number of system applications on an android mobile phone is 275 by way of example, and by combining the formula (1), the probability of extracting the same kernel user identifier is extremely small. Thus, the uniqueness of the combination of the device manufacturer, the device model, the system application package name and the kernel user identification can be ensured.
In general, the number of average system applications on an electronic device such as an android mobile phone is 275, and considering the uncertainty that newly added or deleted system applications may exist after a large version of the electronic device system is upgraded and random collision, when a server side queries, the number of matched system application package names and kernel user identifiers can be properly reduced, that is, 95% of the number of the electronic device system applications can be considered as a preset number, so that the matching rate of unique identifiers of devices querying the electronic device can be improved.
In some embodiments, in S104, if there are device identifiers in the server database that match kernel user identifiers corresponding to system applications in the second device parameter information, that is, if there are more than 95% device identifiers in the server database that are the same number of kernel user identifiers corresponding to system applications in the second device parameter information, the device identifier is returned to the electronic device as a device unique identifier of the electronic device.
In some embodiments, in S105, in the case where there is no device identifier in the server database that matches a kernel user identifier corresponding to a system application in the second device parameter information, for example, if there is no device identifier in the server database that is greater than 95% of the same number of kernel user identifiers corresponding to the system application in the second device parameter information, a snowflake algorithm or a distributed application may be used to generate, according to the kernel user identifier corresponding to the system application in the second device parameter information, a device identifier that matches the kernel user identifier corresponding to the system application in the second device parameter information.
In some embodiments, in S106, after the server generates the device identifier that matches the kernel user identifier corresponding to the system application in the second device parameter information, the generated device identifier and the second device parameter information are bound, stored in a server database in an associated manner, and the device identifier is returned to the electronic device.
Therefore, 95% of the number of the electronic equipment system applications is used as a query matching condition, the unique identification of the global equipment of the bound data is matched for the electronic equipment, the problem that the system application addition and deletion and the uncertainty of random collision of the equipment identification exist in the upgrading of the electronic equipment system applications is fully considered, the unique identification of the electronic equipment is generated based on the uniqueness generated by the kernel user identification and the system application list, and therefore the global uniqueness of the equipment identification is guaranteed.
Fig. 2 is a schematic flow chart of another method for generating a device identifier according to an embodiment of the present application. As shown in fig. 2, the method specifically includes the following steps:
s201, under the condition that a system application installed on the electronic equipment is started, the electronic equipment respectively acquires first equipment parameter information of the electronic equipment from a local cache of the electronic equipment and acquires second equipment parameter information of the electronic equipment from a server, wherein the first equipment parameter information and the second equipment parameter information at least comprise kernel user identifiers corresponding to the system application in the electronic equipment;
S202, comparing whether kernel user identifiers corresponding to system applications in the electronic equipment in the first equipment parameter information and the second equipment parameter information are the same or not under the condition that the first equipment parameter information and the second equipment parameter information both comprise equipment unique identifiers;
s203, under the condition that kernel user identifiers corresponding to system applications in the electronic equipment in the first equipment parameter information and the second equipment parameter information are different, the electronic equipment sends an update request carrying an equipment unique identifier and the second equipment parameter information to a server;
s204, the server updates the device parameter information corresponding to the device unique identifier in the server database according to the second device parameter information.
Therefore, according to the method for generating the device identifier, under the condition that the first device parameter information and the second device parameter information both comprise the device unique identifier, whether the kernel user identifiers corresponding to the system applications in the electronic device in the first device parameter information and the second device parameter information are the same or not is compared, and under the condition that the kernel user identifiers are not the same, the electronic device sends an update request carrying the device unique identifier and the second device parameter information to the server, so that the device parameter information corresponding to the device unique identifier in the server database is updated. Therefore, the consistency of the local cache of the electronic equipment and the identification information of the server equipment can be ensured.
In some embodiments, in S201, the first device parameter information is device parameter information of the electronic device stored in a local cache of the electronic device, and the second device parameter information is device parameter information of the electronic device stored at the server.
In some embodiments, in S202, under the condition that the first device parameter information and the second device parameter information both include the device unique identifier, whether the kernel user identifier corresponding to the system application in the electronic device in the first device parameter information and the second device parameter information is the same is compared, that is, whether the first device parameter information in the local cache, "device manufacturer+device model+system application package name+kernel user identifier" and the second device parameter information in the server "device manufacturer+device model+system application package name+kernel user identifier" are changed is compared, and if no change occurs, other processing is not performed, and the current device unique identifier can ensure the global uniqueness of the device identifier.
In some embodiments, in S203, under the condition that kernel user identifiers corresponding to system applications in the electronic devices in the first device parameter information and the second device parameter information are different, an update request carrying a device unique identifier and second device parameter information, namely, a device manufacturer, a device model, a system application package name and a kernel user identifier, is uploaded to the server through an update request interface provided by the server and used for receiving information modification corresponding to the unique identifier, so that the server updates the device parameter information corresponding to the device unique identifier in the server database according to the second device parameter information.
In some embodiments, in S204, after receiving an update request sent by an electronic device, the server updates device parameter information corresponding to the device unique identifier in the server database according to second device parameter information carried in the update request, so as to ensure consistency between the local cache of the electronic device and the device identifier information in the server.
Therefore, the stability and the uniqueness of the system application package name and the kernel user identifier are utilized, the equipment global unique identifier is generated without depending on the hardware fingerprint identifier and through a flexible screening rule of a server side, the equipment identifier parameter information of the equipment unique identifier is updated in real time, and the stability and the global uniqueness of the equipment identifier are ensured while the consistency of the local cache of the electronic equipment and the equipment identifier information in the server side is ensured.
It should be noted that, the application scenario described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. As a person skilled in the art can know, with the appearance of a new application scenario, the technical solution provided in the embodiment of the present application is applicable to similar technical problems.
