Detailed Description
Other advantages and effects of the present application will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present application with reference to specific examples. The application may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present application. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.
All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The following problems exist in the traditional scheme of acquiring a unique identifier:
1. the field "android_id" in the system setting can change along with the reset of the system or the operation of a user, and cannot be kept unique all the time;
"Mobile identification field (IMEI)" involves privacy compliance issues and system authorization is required for acquisition, otherwise it cannot be acquired;
3. the coverage rate of the advertisement identification library is too small to cover all devices.
In order to solve the above technical problems, the following embodiments of the mobile terminal device unique identifier generating method, apparatus, device and medium are provided.
Example 1
Referring to fig. 1, shown in fig. 1 is a flowchart of a method for generating a unique identifier of a mobile terminal device according to this embodiment. The method specifically comprises the following steps:
step one: the custom character is configured and a string of encrypted random characters is generated.
Specifically, this embodiment configures a global custom character: "CX-", which is used to determine the unique prefix, the custom character can be named arbitrarily. The encrypted random number is generated by a UUID static factory in a public and generic JAVA library.
The UUID static factory generated encrypted random numbers in the UTILS library in Java do not involve any privacy concerns and do not require any high-risk rights, and therefore are preferred to the traditional way of using the "mobile identification field (IMEI)".
In addition, before generating custom characters and generating universal identifier (UUID), the present embodiment first creates a text file for storing the generated unique identifier, creates a text file through the IO library in Java, and stores the text file in the application directory under the name "UUID.
Step two: and combining the custom character with the random character to generate a unique identifier of the equipment.
For example, if the custom character is CX-, and the UUID static factory generates an encrypted random number of "c25c505d-377d-4a9e-850b-f477495b138d", the unique identifier of the combined device is CX-c25c505d-377d-4a9e-850b-f477495b138d ", and the generation of the data breaks through the machine limit of the traditional advertising device identifier, is not limited to only obtaining the unique identifier of a specific mobile phone manufacturer, and is suitable for all android devices.
Step three: and converting the unique equipment identifier into an operable character string, storing the operable character string in equipment, encrypting the unique equipment identifier to obtain a string of encrypted characters, and reporting the string of encrypted characters to a server for storage.
Specifically, the successfully generated unique identifier is saved in the text file for storage, so that the possibility that the unique identifier fails due to the reset of the device or the operation of the application is avoided. The specific implementation logic is as follows:
a. judging whether a file of uuid.txt exists or not, and opening the file in a byte stream form to obtain a BufferedReader object if the file exists;
b. creating a variable character sequence 'StringBuilder' object;
c. circularly reading data in a file in the form of text lines;
d. the read data is put into a created 'StringBuilder' object for type conversion;
e. and converting the 'StringBuilder' object filled with data into an operable character string by a 'toString' method carried by the 'StringBuilder' object.
And encrypting the obtained unique identification data by using MD5 to obtain a string of characters similar to '9 f1947463c468f6545975113999bd 778', and reporting the encrypted data to a server for storage.
The server provides a reporting interface and processes the data reported by the client, and the steps are as follows:
1. creating a post submitting interface of a server side, which is used for receiving data of a client side;
2. analyzing interface data and extracting required values, wherein the acquisition mode is as follows:
a. parsing client data received through the first step in the format of "json" strings, such as "{" msg ": success", ".
encryptedI9 f1947463c468f6545975113999bd778"}" and assigning it to the variable "jsonData";
b. converting the "jsonData" character string variable into a "jsonObject" object through a JSON library;
c. by calling the "jsonObject" self-contained getString () method, the "encrypted" parameter is entered, resulting in the required value of "9f1947463c468f6545975113999bd778".
3. And storing the data into a server database for subsequent updating and maintenance.
In this embodiment, a user opens a client for the first time, and in the case of network connection, the client generates a string of mobile device unique identifiers by combining custom characters with a Universal Unique Identifier (UUID), and stores the mobile device unique identifiers in an internal storage space of an application, which ensures that no duplicate data exists in an installation period. And then, through interaction with the server, reporting the data to the server for matching and storage. The device unique identifier generated by the method provided by the embodiment is suitable for any android mobile device, dangerous authorities do not need to be acquired, privacy problems are avoided, and the security of acquiring the unique identifier is greatly improved. The unique identifier generated by the method provided by the embodiment cannot change along with the reset of the system or the operation of a user, so that the situation that a result cannot be obtained is avoided, the generated character has no sensitive information, and the security level is high.
Example 2
Referring to fig. 2, shown in fig. 2 is a block diagram of a mobile terminal device unique identifier generating apparatus according to the present embodiment. The device specifically comprises the following structures:
the character generation module configures custom characters and generates a string of encrypted random characters;
the unique identifier generation module combines the custom character with the random character to generate a unique identifier of the equipment;
the unique identification storage module converts the unique identification of the equipment into an operable character string to be stored in the equipment, encrypts the unique identification of the equipment to obtain a string of encrypted characters, and reports the string of encrypted characters to the server for storage.
