It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration, and does not limit the structure of the mobile terminal. For example, the mobile terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.
The memory 104 may be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the device identifier generating method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, so as to implement the above-mentioned method. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory located remotely from the processor 102, which may be connected to the mobile terminal 10 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

In one example, the transmission device 106 includes a Network adapter (NIC), which can be connected to other Network devices through a base station so as to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.
Based on the foregoing mobile terminal or network architecture, this embodiment provides a method for generating a device identifier, and fig. 2 is a flowchart of the method for generating a device identifier according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring system starting time, equipment platform information and equipment model of target equipment;
step S204, acquiring the preset creation time of a system folder, and acquiring the current system time;
further, the preset creation time of the system folder is obtained through the attributeuItemAtPath method of the Object-C, and the current system time is obtained through the NSDate function of the Object-C. The Objective-C is a programming language with added object-oriented property expansion on the basis of C, and is generally called jObC and less Objective C or obj C. To some extent, Objective-C can be viewed as a collection of ANSI version C language that supports the same basic syntax of C language, while it also extends the syntax of the standard ANSI C language, including defining classes, methods, and properties. There are of course other structural refinements and extensions, such as the appearance of Category. attributeufietatpath gets all file attributes (fileAttributes) of the given path (path) and returns a dictionary (NSDictionary) to store, i.e. in the form of key-value pairs.
Step S206, generating the device identifier of the target device according to the system starting time, the device platform information, the device model, the creating time and the current system time.
Through the steps S202 to S206, system start time, device platform information, and device model of the target device are obtained; acquiring the creation time of a preset system folder, and acquiring the current system time; the device identifier of the target device is generated according to the system starting time, the device platform information, the device model, the creation time and the current system time, so that the problem that in the related technology, as more and more users are used, when different third libraries in the same APP use OpenUDID to obtain the unique ID of the device, the APP crashes can be solved, the generated device identifier is low in possibility of being repeated, and the application crash is avoided.
In an optional embodiment, after the device identifier of the target device is generated according to the system kernel start time, the device platform information, the device model, the creation time, and the current system time, the device identifier of the target device is stored by a key method of the IOS. The NSDate object encapsulates a point in time, independent of any particular calendar system or time zone. The Date object is immutable, representing an immutable time interval relative to an absolute reference Date (e.g., 1 month 1 day 00:00:00UTC, 2001).
In an embodiment of the present invention, the step S206 may specifically include: splicing the system kernel starting time, the equipment platform information, the equipment model, the creating time and the current system time to obtain splicing information; performing MD5 transcoding on the splicing information to obtain the transcoded splicing information; determining the equipment identification of the target equipment according to the transcoded splicing information, and further intercepting a preset number of characters from the transcoded splicing information according to a preset rule; and determining the preset number of characters as the device identification of the target device.
For example, the start time: 4344409024, platform information: d22AP, device model IPhone10,3, folder creation time: 1549790498, current time: 1597051327213 to obtain: 4344409024D22APIPhone10, 3154979049815970517213 carries out MD5 encryption transcoding to obtain an identification: d46a7f4784bddcb64422ed82c4bf68a 3.
Specifically, intercepting a predetermined number of characters from the transcoded splicing information according to a preset rule may include: intercepting the characters of the preset number from the transcoded splicing information; intercepting the characters of the preset number from the transcoded splicing information; and intercepting the characters with the preset number from the transcoded splicing information.
In the embodiment of the invention, through syscll () and syscllbyname (), the c language of the bottom layer is used;
the functions of the two functions syscll () and sysclbyname () are functions of acquiring or setting system information. Standard UNIX functions are used to query the operating system for detailed information about the hardware and OS. Core information such as the CPU frequency of the system, the amount of memory available, etc. can be checked by constants. It introduces a UIDevice class for gathering system information and returning it through a series of method calls.
Each model provides unique built-in capabilities, knowing exactly which iPhone you are handling helps determine whether that unit is likely to support features such as accessibility, GPS and magnetometer.
The sysctl function returns consistent snapshots as needed for the data. Consistency includes locking into the destination buffer memory so that locking is not needed when data is copied out, and deadlock is avoided when the function sysctl is called.
This specification is described as a name in the form of an MIB, listing the name, the length of which is the parameter namelen.
The syscltbyname function accepts the form of ASCII representing names and numeric names. And it is strictly required to be the same as the standard sysctl function.
The information is copied into the buffer by the parameter oldp. The length of the buffer is specified by the location before the call, while that location gives a large number of copies of the data that return error codes after a successful call and after the call. If that amount of available data is larger than that provided by that buffer, this call provides the largest appropriate data while returning an error code, and if old data is not desired, oldp and oldlenp are set to NULL.
The size of the available data can be made absolute by setting the parameter oldp to NULL and calling the function sysctl. These available data will be returned to the location pointed to by oldlenp. For some operations, the amount of space may change frequently. For these operations, the system may point to the surrounding so that the size of the return is large enough to be the data returned.
To set a new value, newp, the length set to point to a buffernewlen is set by the required value. If a new value is not set, newp should be set to NULL and newlen to 0.
The method comprises the steps of obtaining System kernel starting time, equipment platform information and equipment model, obtaining System folder System/Library/coreservics creating time through an oc attributeOfItemAtPath method, obtaining current System time (accurate to millisecond level) through an oc NSDate function, splicing all the information together, performing MD5 transcoding storage, and generating 32 bits or 40 bits to be stored as equipment unique ID.
The device ID is stored for a long time through a keyhide method of the IOS, and the same device ID can be obtained even if the user uninstalls the APP for reinstallation. The iOS keyhain is a relatively independent space, and information stored in the keyhain key string is not lost by uninstalling/reinstalling the app. Compared with general ways such as NSUserDefaults and plist file storage, the keyhide storage is safer. Therefore, the keyChain is used for storing some private information, such as passwords, certificates, device unique codes (the unique ID acquired from the user device is stored in the keyChain, so that the ID can be acquired after unloading or reloading, and one device is ensured to have one ID), and the like. Keychain was stored with SQLite. The apple is a professional database, the stored data is encrypted, and efficient searching can be performed through metadata (attributes). Keychain is suitable for storing data with a small data volume, and if large data is to be stored, the data can be stored on a disk in a file form, and a key for decrypting the file is stored in the Keychain.
By the method, a 32-bit non-repetitive equipment ID can be generated for distinguishing whether a user activates for the first time, installs an APP and the like. When the user restarts, the APP is unloaded, and the change of the equipment ID cannot be influenced by reinstallation, so that the purposes of distinguishing the uniqueness of the equipment and tracking the user behavior are achieved. For example, device id generation example: d46a7f4784bddcb64422ed82c4bf68a 3.
By the method, a 40-bit non-repetitive equipment ID can be generated for distinguishing whether a user activates for the first time, installs APP and the like. When the user restarts, the APP is unloaded, and the change of the equipment ID cannot be influenced by reinstallation, so that the purposes of distinguishing the uniqueness of the equipment and tracking the user behavior are achieved. For example, device id generation example: b9eef0672f8fce0368f8c6f75ccdce006430a6c 4.
The device id may be generated by adding some additional system information, such as the current remaining space size of the hard disk, the memory usage amount, and the like.

Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
