Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
Fig. 1 shows a flow of a first embodiment of the method of generating a device unique identifier of the present invention. In this embodiment, an implementation of the present invention in an IOS operating system is described as an example.
Step 1: by obtaining the device identifier across the application caching techniques, if the device identifier is successfully obtained and it complies with the rule starting with the 'i.' string, then jump directly to step 4.
The cross-application caching technique is to cache data including a device identifier into a public key string through the seckeyhain interface of the system.
If the acquired character string conforms to the rule with the 'i.' character string as the starting field, it means that the Device unique identifier Device ID is read in this step.
In this embodiment, the character string of 'i.' is taken as the start field only as an example, and in other embodiments, other preset characters can be taken as the start field.
Step 2: based on the acquired Device identifier, a character string serving as a Device unique identifier Device ID is generated.
The step 2 further comprises three steps of processing, each as follows.
Step 2 a: and generating a Universal Unique Identifier (UUID) character string based on the device identifier acquired in the step 1 through a system interface.
Specifically, in step 2a, a UUID string of 32-bit characters is generated by calling the IOS system interface CFUUIDCreate.
And step 2 b: a prefix of 'i.' is provided for the UUID string.
In this embodiment, the prefix of 'i.' is provided for the UUID string only as an example, and in other embodiments, other preset characters may be used to provide the prefix for the UUID string.
And step 2 c: and acquiring the equipment code through a system interface, and adding the equipment code to the rearmost part of the UUID character string to form a three-section long string with the start of 'i.', the UUID middle and the equipment code end and without character string separation.
The device code in step 2c, that is, the model (model) information of the device itself, is obtained through the IOS system API syscllbyname function, and the result is a character string, for example: iPhone11, 8.
The Device ID generated in step 2 is added with the model information (i.e., the Device code number) of the Device itself, compared with the Device ID obtained in step 1.
And step 3: the character string generated in step 2 serving as the Device unique identifier Device ID is cached by applying a caching technique across applications.
And 4, step 4: and outputting the character string generated in the step 2 or obtained in the step 1 as a Device unique identifier (Device ID) to be supplied to a service party.
Fig. 2 shows a flow of a second embodiment of the method of generating a device unique identifier of the present invention. In this embodiment, an implementation of the present invention in an Android operating system is described as an example.
Step 1: reading the character string content in the external storage designated file, judging whether the read character string meets the conditions (the conditions are that the character string is not empty and meets the preset initial format), if so, synchronizing the read character string to the designated file and the designated key in the Shared Preferences storage mode, returning the read character string in advance, and ending the whole process.
For example, a specified file path is created in advance in the external storage, the BUFFERED _ FINAL _ UDID _ KEY in the file path is specified as a custom part, and the KEY value of the KEY is output in the form of a character string, and it is determined whether the character string is empty and conforms to a predetermined beginning format, such as whether it is a character string that begins with' a. In this embodiment, the 'a.' character string is taken as the start field only as an example, and in other embodiments, other preset characters may be taken as the start field.
If the character string read from the user-defined keyword (BUFFERED _ FINAL _ UDID _ KEY) as the KEY value is not empty and conforms to the pre-established beginning format, synchronizing the KEY value (i.e. the character string) to the specified file and the specified keyword in the Shared Preferences storage mode, and then returning the read character string in advance, and ending the whole process.
The sharing options (Shared Preferences) are a lightweight storage class on the Android platform, are used for storing some common configurations of applications, and are suitable for storing lightweight data. It is divided into multiple authorities and can share access globally.
In this step, the purpose of synchronizing to the specified file and the specified keyword key in the Shared Preferences storage mode is to prevent the APP from still being able to acquire the stored content when the externally stored content is deleted objectively.
Step 2: if the character string read in the step 1 does not meet the condition (that is, the condition that the character string is not empty and meets the preset starting format is not met), continuing to read the key-value character string corresponding to the designated file and the designated key in the Shared Preferences storage mode, if the key-value character string read in the step 2 meets the condition (that is, the condition that the character string is not empty and meets the preset starting format is met), then synchronously writing the key-value character string read in the step 2 into the external storage designated file, checking whether the corresponding access authority to the external storage exists before the key-value character string is written into the external storage designated file, and if the access authority does not exist, not doing the writing operation, and returning the key-value character string stored in the Shared Preferences read in the step 2 in advance.
And step 3: if the key-value character string read in the step 2 does not meet the condition (namely, does not meet the condition that the character string is not empty and meets the preset starting format), a character string starting with 'A.' is created, a format of a final unique identifier of the equipment is formed after splicing and encryption processing is carried out on a plurality of fields based on ANDROID _ ID (equipment mark, equipment ID which is easily accessed by an ANDROID system and provided for an application) acquired from the system, the value of the final format is synchronized into a specified file directory and a specified key (key) in a Shared Preferences storage mode, and the specified file is stored externally.
Similarly, in the above processing, the a.' character string is taken as the start field only as an example, and in other embodiments, other preset characters may be taken as the start field.
The value of the ANDROID _ ID is changed with the ANDROID system, is an ID unique to the ANDROID system, is a 64-bit number randomly generated when the ANDROID system is started for the first time, and also changes after the system is refreshed, and meanwhile, a manufacturer customizes a Bug of the system to cause different devices to possibly generate the same ANDROID _ ID, and the ANDROID _ ID acquired by some devices is null.
In consideration of the above situation, the other fields are first spliced with the ANDROID _ ID (the other fields are combinations of timestamps, models, device hardware names, and device hardware identifiers, for example), then the spliced contents of the fields are encrypted by md5, and after a 32-bit encrypted string is generated, the string is spliced with the previously created string beginning with 'a.', so as to form the final format of the device unique identifier: "a" (32-bit string generated by md5 encryption) ".
The synchronization to the external storage designated file is to achieve that the same unique mark can be obtained by using an SDK (software development kit) or an APP under the generation mode, and the synchronization to the external storage designated file is stored in the designated file directory and the keywords of the SP to prevent the external storage file from having no content due to the problems of authority and the like and further being read from the current private directory.
