Description
Technical Field
The present application relates to the field of internet technologies, and in particular, to a method, an apparatus, and a storage medium for generating a unique device identification code.
Background
In the internet field, the premise of ensuring the safe operation of the service is to perform the service operation according to the equipment identification code of the user equipment. Therefore, it is important to generate a reliable and unique device identification code. At present, a method for generating a unique identification code of equipment is provided in an Android system, but stability and uniqueness are not ideal due to limitations of Android system versions, Bug in a manufacturer customized system and the like. And the identification through other hardware information has problems of different degrees due to the limitation of system version, mobile phone hardware and the like. Generally, the following methods are used for generating a device unique identification code in an Android device:
1. MAC refers to a unique identification code of the device network card, which is globally unique and is generally called a physical Address, and a hardware Address is used to define the location of the device.
2. The International Mobile Equipment Identity (IMEI) is also known as the Equipment identification number (Device Id). At present, a Global System for Mobile Communications (GSM)/Wideband Code Division Multiple Access (W-CDMA)/Long Term Evolution (LTE) Mobile phone terminal needs to use an IMEI number, one Mobile phone number corresponds to one IMEI number in a single card project, and a dual-card Mobile phone corresponds to two IMEI numbers, one Mobile phone number corresponds to one Mobile phone card.
ANDROID _ ID: when the device is first operated, the system randomly generates a 64-bit number and stores the number in 16, where the 16 is the ANDROID ID, but the value changes if the handset is restored to factory settings.
4. Sequence Number (Serial Number): starting from Android 2.3, a serial number can be obtained by an Android.
UniquePsuedoID: and assembling the acquired content, such as manufacturer, model and resolution, of the hardware information of the equipment.
However, the above listed methods all have certain drawbacks, and cannot guarantee accurate identification of the device identification code of a certain user equipment. Among the disadvantages of each approach are the following:
1. the MAC address of the wireless network card: after the Android 6.0 version, when acquiring the mac address, the Android operating system interface returns the default mac address of "02:00:00:00:00:00", which is obtained by the fact that the google official disables the getSystemservice (context.WIFI _ SERVICE) method for reinforcing the authority management.
IMEI number (DeviceId): if the user forbids to make a call, the acquisition is unsuccessful, and then the user is prompted to consider the call making permission on product design, which can influence the user experience;
3.ANDROID_ID：
a. the value changes after the mobile phone is restored to factory settings;
b. in a domestic Android-customized large environment, some devices do not return Android _ IDs.
4. Serial number (serial number) no authority is required to acquire the serial number, but certain limitations exist, and junk data can occur on some mobile phones, for example, a continuous non-random number is returned by a red-rice mobile phone.
UniquePsueDoID, which is directly related to device information and may be the same if the generated content is likely to appear in devices shipped from the same lot, cannot be used to generate a unique identifier if the method is used alone.

and S11, acquiring first device information of the user device.
In this step, the server acquires first device information of the user device. Specifically, when the user equipment is installed for the first time or the unique identification code is not cached, the server acquires the first equipment information from the user equipment. Here, the first device information is mainly a device description about the user device, and the first device information at least and not limited to include device basic information, device software version information, device hardware information, and user setting information.

S12, based on the first device information, searching whether second device information matched with the first device information exists in the database, and when the second device information is not searched, generating a unique identification code corresponding to the user device according to the first device information.
In this step, after the first device information of the user device is obtained, whether the second device information matched with the first device information is cached or not is searched in a database of the user device according to the first device information. The second device information is the same as the information represented by the first device information. And matching the information contained in the first equipment information with the stored equipment information in the database, and calculating the similarity between the first equipment information and each piece of stored equipment information when the second equipment information matched with the first equipment information is not found so as to further find whether the second equipment information exists in the database.
Further, if the second device information is not found in the database, the unique identification code of the user device is generated according to the first device information.
And S13, sending the unique identification code to the user equipment corresponding to the first equipment information.
In this step, the server issues the generated unique identification code to the user equipment corresponding to the first device information.
As described above, based on the above embodiment, first device information of the user equipment is first obtained, then, based on the first device information, whether second device information matching the first device information exists is searched in the database, and when the second device information is not searched, a unique identification code corresponding to the user equipment is generated according to the first device information, and finally, the unique identification code is sent to the user equipment corresponding to the first device information. According to the embodiment of the application, the unique identification code of the user equipment is generated through the first equipment information acquired from the user equipment terminal and is stored in the database. When the second device information corresponding to the first device information does not exist in the database, the unique identification code of the user device is generated according to the first device information, the unique identification code of the user device does not depend on local storage, and the reliability and uniqueness of the identification code of the user device are guaranteed.
Fig. 2 is a schematic diagram illustrating a specific flow of a method for generating a device unique identifier according to an embodiment 200 of the present application. Wherein, the detailed process of the specific flow is as follows:
s201, first device information of the user device is obtained.
Here, the case where the server acquires the first device information of the user equipment is that the user equipment is installed for the first time or the unique identification code is not stored or erased locally in the user equipment. At this time, the server acquires first device information of the user device, including device basic information, device software version information, device hardware information, user setting information, and the like. The user equipment can upload the first equipment information to the server by using the http protocol.
S202, whether second equipment information matched with the first equipment information one by one exists or not is searched in the database.
Here, whether there is second device information that matches the device basic information, the device software version information, the device hardware information, and the user setting information one-to-one is searched for in the data based on the device basic information, the device software version information, the device hardware information, and the user setting information included in the first device information. Specifically, after acquiring first device information uploaded by the user device, the server matches device basic information, device software version information, device hardware information, and user setting information included in the first device information with each item of information included in stored device information in the database one by one, and determines the stored device information matched one by one as second device information.
And S203, calculating the similarity between the first equipment information and the stored equipment information.
Here, when the second device information is not found, the similarity between the first device information and the stored device information in the database is calculated, and the stored device information corresponding to the similarity larger than the preset threshold is used as the second device information. Specifically, when the scheme in step S202 is performed and the second device information corresponding to the first device information is not found, the server calculates the similarity between the first device information and the stored information through a similarity calculation method. Here, if the user changes the first device information of the user device and the user device already has the unique device code, at this time, the stored information with high similarity is searched in the database as the second device information by the similarity algorithm, and the unique device code corresponding to the second device information is acquired, so that the uniqueness of the user device is ensured. And the server calculates the similarity between the first equipment information and the stored equipment information through similarity algorithms such as a SimHash algorithm or a Jaccard algorithm.
And S204, judging whether the similarity value is larger than a preset threshold value.
Here, when the similarity value is higher than the preset threshold value, the stored information may be considered as the second device information corresponding to the first device information. The preset threshold may be set according to an empirical value. And according to the first equipment information, calculating the similarity through similarity algorithms such as a SimHash algorithm or a Jaccard algorithm and the like, and determining the best matching search result when the similarity value is greater than a preset threshold value.
And S205, using the stored device information corresponding to the similarity greater than the preset threshold value as second device information.
And S206, generating a unique identification code corresponding to the user equipment according to the first equipment information.
Here, the device basic information, the device software version information, the device hardware information, and the user setting information included in the first device information are compressed to generate a message digest of the first device information, and the message digest is used as a unique identification code of the user device. Can be generated according to the respectively held hash algorithm (such as md5, sha-1 and the like) to ensure the uniqueness of the generated message digest.
And S207, sending the unique identification code to the user equipment corresponding to the first equipment information.
In this step, the unique identification code stored in the database corresponding to the second device information is sent to the user device corresponding to the first device information, and the unique identification code corresponding to the user device is generated according to the first device information.
The method for generating the unique identification code of the equipment is realized based on the steps. The method comprises the steps of obtaining a data set formed by first equipment information of user equipment. Further, in a database of the server, whether a unique device code corresponding to the user equipment has been generated and cached is searched through a similarity algorithm such as SimHash or Jaccard or matching. If the matching is successful, the second equipment information corresponding to the first equipment information already exists in the database, and the server returns the matched unique identification code of the equipment to the client; if the matching fails, the user equipment is possible to be a new user, the first equipment information and the generated unique identification code are stored in a database, and the unique identification code is returned to the user equipment. The server generates a unique identification code of the user equipment and then sends the unique identification code to the user equipment, the user equipment stores the unique identification code to the local, in the subsequent using process, the user equipment preferentially obtains the unique identification code from the local cache, and if the unique identification code in the local cache is cleared, the process of re-acquiring the first equipment information and uploading the first equipment information to the server to search the unique identification code is triggered.
According to the embodiment of the application, the user equipment and the server side are matched to maintain a large amount of equipment information data through the steps, the user equipment does not completely depend on local storage, the risk that the data are erased can be avoided, and the data are sent to be acquired in real time when needed. And the server side calculates the similarity of the samples by using similarity algorithms such as SimHash or Jaccard and the like, matches the best result, and ensures the reliability and the uniqueness of the unique identification code of the user equipment.
