The application can be provided independently of the operating system, or it can be provided by the operating system itself.

Among the various applications 154, one of them is an identifier generating device, which can obtain multiple identifiers in the mobile terminal, determine available identifiers among the multiple identifiers, and then generate a unique identifier for the mobile terminal character, improve user experience, and ensure the uniqueness of the mobile terminal, which will be described in detail below.

Fig. 2 shows a flow chart of a method for generating an identifier according to an embodiment of the present invention. As shown in FIG. 2, the method is executed in a mobile terminal, and the above method starts at step S210.

In step S210, the own application identifier and identifier information in the mobile terminal are obtained, and the above identifier information includes a plurality of identifiers. Wherein, each application installed in the mobile terminal has an identifier, and the above-mentioned application identifier is an identifier of the application executing the method for generating the identifier, such as packageID. The identifier information in the mobile terminal is the identifier of other applications in the mobile terminal (excluding the application that executes the method for generating the identifier), such as the identifier of the call application or the serial number of the network card in the mobile terminal. The identifier is generally in the form of a character string, for details, refer to FIG. 3 .

Generally, there are many identifiers in a mobile terminal such as a mobile phone running an Android operating system, and all the identifiers in the mobile phone can identify the uniqueness of the mobile phone. For example, International Mobile Equipment Identifier (IMEI), Communication Identifier (Pseudo-UniqueID), Wireless Module Identifier (The WLAN MAC Address), Bluetooth Module Identifier (The BT MAC Address) and so on.

IMEI can obtain the IMEI information of the Android device by obtaining the TelephonyManager object in the Android operating system, and then calling the getDeviceId interface of the TelephonyManager object. The code for obtaining the IMEI is as follows: TelephonyManagerrtm=(TelephonyManager)getSystemService(TELEPHONY_SERVICE); String szImei=tm.getDeviceId(). Among them, getSystemService(TELEPHONY_SERVICE) is used to obtain the TelephonyManager object.

The communication identifier is an identifier of the call application in the mobile terminal. If the mobile terminal does not have a call function, or there is a problem with the call function, then the identification code may not be obtained. Generally, the hardware information androidBuildId of the mobile phone device obtained by the component Build in the Android operating system, considering that each hardware information is relatively long, so the present invention only obtains the value of the remaining 10 of the length of each hardware information, that is, each hardware information The length value of the information is spliced with the remaining 10 information, and finally a 12-digit number is obtained.

The wireless module identifier is only available for mobile terminals with wireless modules. For some customized or industrial equipment, if you do not add a wireless module for safety, you cannot use this function to obtain the identifier. The mobile terminal obtains the information interface info of the wireless module through the WiFi interface getConnectionInfo, such as, WifiInfo info=wifi.getConnectionInfo (), and then the MAC address wifiMac of the wireless module can be obtained through the getMacAddress interface of the info interface, such as, String wifiMac=info.getMacAddress ().

Similarly, for the Bluetooth module identifier, the identifier can only be obtained if it has the Bluetooth function. For example, to obtain the BluetoothAdapter instance in the Android operating system, BluetoothAdapter badapter=BluetoothAdapter.getDefaultAdapter(), and obtain the MAC address by calling the interface getAddress of the BluetoothAdapter, String m_szBTMAC=badapter.getAddress().

However, it should be understood that the identifiers obtained in the present invention are not limited to the above-mentioned types, and all identifiers that can be obtained and can be used to distinguish mobile terminals are within the protection scope of the present invention.

In step S220, the correct identifier among the plurality of identifiers in the identifier information is determined.

Since the identifier acquired in step S210 may be wrong, it is necessary to determine the correct identifier acquired. In one embodiment, each identifier in the identifier information is traversed, and whenever it is determined that the number of repetitions of each character in the current identifier is less than a predetermined number of times, the above-mentioned current identifier is determined to be the correct identifier, until all identifiers The character judgment is completed, wherein, the predetermined number of times is half of the length of the identifier. When traversing identifiers, characters are saved in storage data. For example, storage data is a map object, and map is a container in the template library (STL). Data is generally stored in the form of key/value pairs. The character is stored in the key of the map object, and the number of occurrences of the character is stored in the value of the current key. For example, the obtained identifier is Abbbbbbbbbc, and if the same key is found, the value of the key is increased by 1. After traversing the current identifier, it is found When the key is character b, the value is 9, and the length of the string is 11. If the value is greater than the length of the string, the identifier is discarded.

In step S230, after it is determined that there is at least one correct identifier in the identifier information, generate a target identifier from the at least one correct identifier.

According to an implementation manner, after it is determined that there is at least one correct identifier in the identifier information, a first rule is used to generate the target identifier from the at least one correct identifier.

If it is determined in step S220 that there is a correct identifier, the current correct identifier is used as the target identifier. If it is determined in step S220 that there is more than one identifier such as 2 correct, at this time, the two correct identifiers can be simply spliced as the target identifier, such as, the two identifiers are respectively asabcdfg and qwedfsso, the target identifier The character can be asabcdfgqwedfsso. It is also possible to confuse the two identifiers, and use the obfuscated character string as the target identifier. Taking the above two identifiers as an example, the target identifier is assoceddqwfgfsab at this time.

According to another implementation manner, after it is determined that each identifier in the identifier information is incorrect, the second rule is used to generate the target identifier. For example, if the correct identifier is not determined in step S220, at this time, the character string randomly generated by the random number generator can be used as the target identifier, the length of the character string is determined according to the actual situation, and the above-mentioned target identifier generated by SharePreference is saved locally.

However, it should be understood that all rules that can generate target identifiers are within the protection scope of the present invention. All files that can store target identifiers are also within the protection scope of the present invention.

In step S240, a unique identifier of the mobile terminal is generated according to the target identifier and the application identifier.

According to one embodiment, the target identifier and the application identifier are combined using a first encryption algorithm to obtain an encrypted identifier. The encrypted identifier is encrypted by using the second encryption algorithm to obtain the unique identifier of the mobile terminal. For example, the target identifier in step S230 is simply combined with its own application identifier, and the string after the simple combination is encrypted using an MD5 algorithm or a hash algorithm to obtain an encrypted string, and then using the US data encryption standard ( DES algorithm) encrypts the above-mentioned encrypted string again to obtain the unique identifier of the mobile terminal. In one embodiment, the application in the mobile phone is a paid application. The application in the mobile phone obtains the unique identifier of the mobile phone and sends it to the server. The server will save the unique identifier. When the application in the mobile phone is opened by the user again, the server will only It is necessary to verify whether the current application is paid, and there is no need to verify the identifier again.

According to the technical solution of the present invention, the uniqueness and accuracy of the identifier in the mobile terminal is guaranteed by adding its own application identifier to the obtained correct identifier in the mobile terminal and encrypting to obtain a unique identifier.

The information acquiring unit 410 acquires its own application identifier and identifier information in the mobile terminal, where the identifier information includes multiple identifiers. The specific identifiers have been described in detail above, and no further explanation is given here.

The information processing unit 420 determines the correct identifier among the plurality of identifiers in the identifier information. For example, the information processing unit 420 traverses each identifier in the identifier information, and whenever it is determined that the number of repetitions of each character in the current identifier is less than a predetermined number of times, it is determined that the current identifier is a correct identifier until All of the identifiers are determined.

After the information processing unit 420 determines that there is at least one correct identifier in the identifier information, the first generation unit 430 generates the target identifier from the at least one correct identifier. For example, after determining that there is at least one correct identifier in the identifier information, the first generating unit 430 uses the first rule to generate the target identifier from the at least one correct identifier. If the information processing unit 420 determines that each identifier in the identifier information is incorrect, the first generation unit 430 generates the target identifier by using the second rule.

The second generating unit 440 generates a unique identifier of the mobile terminal according to the target identifier and the application identifier. For example, the second generating unit 440 uses the first encryption algorithm to combine the target identifier and the application identifier to obtain an encrypted identifier. The encrypted identifier is encrypted by using a second encryption algorithm to obtain the unique identifier of the mobile terminal.
