Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for generating terminal identification information.
Background
In the conventional technology, in order to distinguish different terminals, an operating system on the terminal generally needs to generate identification information according to the software and hardware environment of the terminal. For example, a common Mobile phone terminal usually uses an International Mobile Equipment Identity (IMEI, a piece of identification information stored in a Mobile phone firmware) or an International Mobile subscriber Identity (IMSI, a piece of identification information stored in a Mobile phone SIM card) to distinguish different terminals, and for a network terminal accessing the internet, such as a personal computer or a notebook computer, a physical address (MAC) of a network card is usually used to distinguish the terminals.
However, in the conventional technology, the above-mentioned manner of using IMEI, IMSI or MAC as the identification information has certain problems. Some application frameworks and plug-ins in the existing operating system, for example, software such as Xpose framework or 008 god ware, may modify identification information such as IMEI, IMSI, or MAC on the mobile terminal, and the modification may be performed by directly modifying the IMEI, IMSI, or MAC value stored in each specific storage area, or by modifying a function value for reading the identification information such as IMEI, IMSI, or MAC, so as to cause corresponding service activities to be performed by modifying the IMEI, IMSI, or MAC of some terminals to pretend to be the identity of other terminals, that is, the existing identification information for distinguishing terminals is relatively easy to be tampered.
Disclosure of Invention
Therefore, in order to solve the technical problem of insufficient security caused by the fact that the mode of taking the IMEI, IMSI or MAC and other identifications as the terminal identification information in the traditional technology is easy to modify and forge, a method for generating the terminal identification information is provided.
A method of generating terminal identification information, comprising:
receiving a terminal identification information generation instruction;
acquiring an installed application list, wherein the application list comprises at least one application identifier;
mapping the application identification in the application list into identification information;
and returning the identification information.
In addition, in order to solve the technical problem of insufficient security caused by the fact that the way of using the IMEI, IMSI or MAC identification as the terminal identification information in the traditional technology is easy to modify and forge, a device for generating the terminal identification information is specially provided.
An apparatus for generating terminal identification information, comprising:
the instruction receiving module is used for receiving a terminal identification information generation instruction;
the list acquisition module is used for acquiring an installed application list, and the application list comprises at least one application identifier;
the identification information mapping module is used for mapping the application identification hash in the application list into identification information;
and the identification information returning module is used for returning the identification information.
The embodiment of the invention has the following beneficial effects:
after the method and the device for generating the terminal identification information are adopted, the identification information of the terminal does not depend on a single IMEI, IMSI or MAC which is easy to be tampered, but is generated according to the application identifier of the application installed on the terminal. For different terminals, if a counterfeiter wants to tamper the identification information of the terminal, the application on the terminal needs to be installed or uninstalled, and compared with a simple mode of modifying a machine identification code in the traditional technology, the time consumption is more, so that the terminal is more inconvenient to forge, and therefore, in an application scene of counting the number of terminals based on the identification information, statistical data can be effectively prevented from being forged by lawless persons.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As described above, in the conventional technology, hardware information such as IMEI, IMSI, MAC, etc. of the mobile device is generally used as identification information to distinguish the mobile device, but the hardware information may be modified. For example, the Xposed framework is a framework service that can affect the program running (modify the system) without modifying the APK, and based on it, many powerful modules can be made and operated simultaneously without function conflicts. The Xpos-based framework can provide various hardware access environment parameters such as false IMEI, IMSI, MAC, screen resolution, model, SIM card number, cell phone number, geographic location, operator number or name, cell phone OS version, etc. to the specified program.
A typical tool based on the Xposed framework is the 008K god. In channel promotion, each different IMEI fingerprint (or fingerprint formed by combining information such as IMEI + IMSI + MAC) represents a new user, and a tool like a 008K god is widely used for manufacturing false users (namely channel brushing amount). The existing mobile phone measurement tool can shield the APP package name of the tool or some sensitive APP package names, and the APP package name is prevented from appearing in an application list of a mobile phone, so that the APP package name is prevented from being detected.
For example, when counting the number of registered users of an application, it is generally necessary to distinguish terminals by using IMEI, IMSI or MAC, thereby preventing the users from repeatedly registering. The user can write different IMEI, IMSI or MAC on a small amount of mobile phones through a 008K magic device, and the identification information of the terminal can be tampered, so that a small amount of mobile phones can be used for registering for a large number of times, and the number of registered users is forged.
In order to solve the above-mentioned technical problem of insufficient security caused by the way of using the identifier such as IMEI, IMSI or MAC as the terminal identification information in the conventional technology, a method for generating the terminal identification information is provided, which can be implemented by relying on a computer program that can run on a computer system based on von neumann architecture, such as a smart phone, a tablet computer, a notebook computer, a personal PC, or other computer device.
Specifically, as shown in fig. 1, the method for generating the terminal identification information includes the following steps:
step S102: and receiving a terminal identification information generation instruction.
The terminal identification information generation instruction is used for informing the terminal to generate the terminal identification information. The terminal identification information may be transmitted from an external server or may be generated by the terminal itself according to the program operation.
For example, if a plurality of terminals need to maintain connection with a server and the server needs to perform a service processing for the plurality of terminals simultaneously and asynchronously, the server needs to distinguish the plurality of terminals. Therefore, the server may transmit a terminal identification information generation instruction to the terminal when each terminal establishes a connection with the server or registers in the server, notifying the terminal to return the terminal identification information (or the terminal may trigger generation of the terminal identification information generation instruction when generating a connection request or a registration request, and then attach identification information in the connection request or the registration request). Then the server establishes a session corresponding to the identification information, and when the terminal is disconnected and reconnected, the server can search the session according to the same identification information, thereby recovering the service processing process before disconnection.
Step S104: and acquiring an installed application list, wherein the application list comprises at least one application identifier.
The installed application list is an installed application program list or an installed app list on the terminal. The installed application list includes application identifiers of installed application programs or apps.
For example, in an Android (Android) system, a packagemanager management class is provided, and a package name of an application installed on a terminal where the Android system is installed (for example, an entry of a calendar application is com.
In the IOS system, the runtime, which provides the lsappticationworkpace _ class, acquires the class of the installed application list, or may also acquire the installed application list by reading com.
Step S106: and mapping the application identification in the application list into identification information.
Step S108: and returning the identification information.
As described above, if the application identifiers (package names of applications) included in the acquired installed application list are as follows:
android；
com.android.backupconfirm；
com.android.bluetooth；
com.android.calendar；
com.android.certinstaller；
com.android.contacts；
com.android.defcontainer”
……
in this embodiment, the obtained application identifiers may be mapped into hash values by a preset hash algorithm through hash mapping, and then the hash values are output as identification information. The application identifications in the application list may also be sorted before the step of the terminal classifying the application identifications in the application list into a plurality of application identification subsets. The method and the device avoid different identification information generated by the same equipment due to inconsistent acquisition of the application identification sequence.
For example, the plurality of application identifiers may be concatenated into a character string, and then the concatenated character string may be mapped into a hash sequence value using the MD5 algorithm, and then the hash sequence value may be output as identification information of the terminal.
For another example, a preset length of the identification information may be set, for example, 64 bits may be defined as the length of the identification information, and then the application identifiers in the installed application list are traversed through a preset hash algorithm, and the traversed application identifiers are sequentially mapped to a certain bit or bits of the identification information. And then outputting the identification information obtained after the traversal is finished.
Preferably, the step of the terminal hashing and mapping the application identifier in the application list into the identification information includes:
classifying the application identifications in the application list into a plurality of application identification subsets, wherein the application identification subsets comprise at least one application identification; and Hash mapping the plurality of application identifier subsets into identification information with preset digits.
As in the above example, the obtained application identifiers in the installed application list may be grouped, and the grouped application identifiers are
Android，com.android.backupconfirm；
com.android.backupconfirm，com.android.bluetooth；
com.android.bluetooth，com.android.calendar；
com.android.calendar，com.android.certinstaller；
com.android.certinstaller，com.android.contacts；
com.android.contacts，com.android.defcontainer”；
The terminal can traverse the application identifier subsets obtained through classification, splice the character strings of the application identifiers contained in the traversed application identifier subsets, and map the spliced character strings into binary codes with preset digits according to a preset hash algorithm.
As described above, the MD5 code may be used to perform hash mapping on the character string obtained after splicing, or traverse the character string obtained by the application identifier, sequentially map the traversed character string to a certain bit or certain bits of the identification information with a preset length, and then output the identification information obtained after traversing is finished.
Further, in this embodiment, a method for hash mapping a plurality of application identifier subsets into identification information with preset bits is further provided, and specifically, as shown in fig. 2, the method includes:
step S202: and setting a weight parameter for each application identification subset obtained by classification.
The weight coefficient is a parameter used for representing the importance of a certain application identifier in the hash mapping process, and in this embodiment, all the weight coefficients may be set to the same value; in other embodiments, the weight coefficient may also be set according to the application type corresponding to the application identifier subset or the number of application identifiers included in the application identifier subset.
For example, if the applications are divided into the system-owned application and the user-installed application, the weighting factor of the application identifier of the system-owned application may be set to 1, and the weighting factor of the user-installed application may be set to 2. If the number of the preset application identifier subsets is 2, if a certain application identifier subset comprises application identifiers of two systems with own applications, the weight coefficient is 1; if a certain application identifier subset comprises application identifiers of two user installation applications, the weight coefficient is 2; if an application identifier subset comprises an application identifier of a system self-contained application and an application identifier of a user installation application, the weighting coefficient is 1.5.
Step S204: and mapping each application identifier subset obtained by classification into a binary code with the preset digit through a preset hash algorithm.
That is to say, in the present embodiment, the hash mapping includes a two-part mapping process, in the first part of the mapping process, a preset hash algorithm is first used to map each application identifier subset to a binary code with a preset number of bits, so as to obtain a plurality of binary code sequences, and then the binary code sequences are mapped to the finally output identification information.
As mentioned above, in step S204, the hash mapping process of the first part in this embodiment is completed, and a sequence of binary codes corresponding to each application identifier subset is obtained, and the hash mapping process of the second part is described in detail below with reference to the hash mapping process shown in fig. 3, that is, the obtained sequence of binary codes is mapped into the identification information of the final output.
Step S206: and generating a weight parameter sequence corresponding to each application identifier subset according to the binary code and the weight coefficient of each application identifier subset, wherein in the weight parameter sequence, the absolute values of sequence values are the weight parameters of the application identifier subset corresponding to the weight parameter sequence, and the value of the binary code corresponding to the weight parameter sequence on each bit determines the positive and negative signs of the sequence value of the corresponding position in the weight parameter sequence.
In FIG. 3, W1To WnIdentifying for each said application a corresponding weight coefficient of the subset; w1Corresponding 100110, W2Corresponding 110000 …, WnThe corresponding 001001 is a sequence of binary codes corresponding to each subset of application identifiers. The length of the identification information preset in this example is 6 bits.
That is, the application identifier subset numbered 1 corresponds to a weight coefficient W1And the hash value of the preset length obtained after the hash mapping is performed on the application identifier subset numbered 1 in step S204 is 100110, the obtained weight parameter sequence corresponding to the application identifier subset numbered 1 is as follows:
+W1，-W1，-W1，+W1，+W1，-W1；
that is, the weight coefficient corresponding to the application identifier subset numbered 1 determines that the absolute value of each sequence value in the corresponding weight parameter sequence is W1(ii) a The binary code 100110 corresponding to the application identifier subset numbered 1 determines that the signs of each sequence value in the corresponding weight parameter sequence are +, -, +, +, +, -;
step S208: and generating initialized identification information of the preset digit.
As in the previous example, the length of the preset identification information is 6 bits, and the preset identification information may be 000000.
Step S210: traversing the bits of the identification information, acquiring the sequence value of the weight parameter sequence of each application identifier subset at the sequence position corresponding to the traversed bits, calculating the sum of the acquired sequence values, and setting the numerical value of the identification information at the traversed bits according to the sign of the calculated sum.
Referring again to fig. 3, for the 1 st bit of the identification information of 6 bits, the 1 st bit in the weight parameter sequence corresponding to each application identifier subset may be obtained first.
For example, for the application numbered 1, the weight parameter sequence corresponding to the subset is identified:
+W1，-W1，-W1，+W1，+W1，-W1the first bit is + W1；
For the application numbered 2, the weight parameter sequence corresponding to the identification subset:
+W2，+W2，-W1，-W1，-W1，-W1the first bit is + W2；
For the application with the number n, the weight parameter sequence corresponding to the identification subset is as follows:
-Wn，-Wn，+Wn，-Wn，-Wn，+Wnthe first bit is-Wn；
The 1 st bit of the finally obtained identification information corresponds to + W1+W2…-WnIs of a sign of, i.e., if + W1+W2…-WnIf the value of (1) is greater than 0, the 1 st bit of the finally obtained identification information is 1; if + W1+W2…-WnIf the value of (d) is less than or equal to 0, the 1 st bit of the finally obtained identification information is 0.
By analogy, the 2 nd bit of the 6-bit identification information corresponds to-W1+W2…-WnThe sign of (a). That is, if-W1+W2…-WnIf the value of (1) is greater than 0, the 2 nd bit of the finally obtained identification information is 1; if-W1+W2…-WnIs less than or equal to 0, the identification information finally obtainedThe 2-bit is 0.
By analogy, the 6 th bit of the 6-bit identification information corresponds to-W1-W2…+WnThe sign of (a). That is, if-W1-W2…+WnIf the value of (1) is greater than 0, the 6 th bit of the finally obtained identification information is 1; if-W1-W2…+WnIs less than or equal to 0, the 6 th bit of the finally obtained identification information is 0.
In this embodiment, if the sequence formed by the sum of the finally obtained sequence values is 13, 108, -22, -5, 32, 55 as shown in fig. 3, the corresponding sign sequence is positive, negative, positive, and then the finally output identification information is 110011.
The role of the method in practical application will be described below with reference to a specific application scenario.
In the context of an application platform (e.g., application treasure, application marketplace, software manager, etc.), multiple applications are registered with the application platform. The application program can be released by a third-party manufacturer, and a user can browse the released application after accessing the application platform. The application platform has management and statistical functions for the registered applications.
For example, the application platform may count the number of downloads of the registered applications, and the number of downloads corresponds to the number of terminals, that is, the server of the application platform counts the number of terminals downloading or installing a certain application, and therefore, the terminal is required to provide identification information so that the server of the application platform can distinguish the terminals and can conveniently count the terminals.
In the conventional technology, in order to create the illusion that the downloaded amount of the published application is large or the installed amount is large, some third-party application publishers use a code-swiping mode, namely, a small number of mobile phones are used, and the download and installation times counted by a server of an application platform are inaccurate by writing different IMEI codes and repeatedly downloading the IMEI codes in a short time.
In the application scenario, when a user downloads or installs an application, the server of the application platform notifies the terminal to upload the identification information of the terminal, and the identification information is generated according to the installed application list of the terminal, and a publisher of a third-party application cannot forge the identification information of the terminal by writing an IMEI code, so that the downloaded and installed data counted by the server of the application platform is more real. That is, for a terminal that has been counted, a user who counterfeits the statistical information must perform an operation of installing or uninstalling an application to the terminal (more than one application that may need to be installed and uninstalled according to a difference of hash algorithms), and therefore, for a counterfeit demand that requires counterfeiting a large amount of downloaded installation data in a short time, the identification information generated from the installed application list of the terminal effectively prevents the situation of counterfeiting the statistical data, thereby making the statistical data more authentic.
In order to solve the above-mentioned technical problem of insufficient security caused by the fact that the way of using the identifier such as IMEI, IMSI or MAC as the terminal identification information in the conventional technology is easily modified and forged, an apparatus for generating the terminal identification information is provided, the apparatus includes an instruction receiving module 102, a list obtaining module 104, an identification information mapping module 106 and an identification information returning module 108, wherein:

an identification information mapping module 106, configured to hash the application identifier in the application list into identification information;
and an identification information returning module 108, configured to return the identification information.
Optionally, in this embodiment, the identification information mapping module 106 is further configured to: classifying the application identifications in the application list into a plurality of application identification subsets, wherein the application identification subsets comprise at least one application identification; and Hash mapping the plurality of application identifier subsets into identification information with preset digits.
Optionally, in this embodiment, the identification information mapping module 106 is further configured to: setting a weight parameter for each application identifier subset obtained by classification; mapping each application identifier subset obtained by classification into a binary code with the preset digit through a preset hash algorithm; generating a weight parameter sequence corresponding to each application identifier subset according to the binary code and the weight coefficient of each application identifier subset, wherein in the weight parameter sequence, the absolute values of sequence values are the weight parameters of the application identifier subset corresponding to the weight parameter sequence, and the value of the binary code corresponding to the weight parameter sequence on each bit determines the positive and negative signs of the sequence value of the corresponding position in the weight parameter sequence; generating initialized identification information of the preset digit; traversing the bits of the identification information, acquiring the sequence value of the weight parameter sequence of each application identifier subset at the sequence position corresponding to the traversed bits, calculating the sum of the acquired sequence values, and setting the numerical value of the identification information at the traversed bits according to the sign of the calculated sum.
Optionally, in this embodiment, the identification information mapping module 106 is further configured to: traversing the application identifier subsets obtained by classification, splicing character strings of the application identifiers contained in the traversed application identifier subsets, and mapping the spliced character strings into binary codes with preset digits according to a preset hash algorithm.
Optionally, in this embodiment, the identification information mapping module 106 is further configured to: and sorting the application identifications in the application list.
The embodiment of the invention has the following beneficial effects:
after the method and the device for generating the terminal identification information are adopted, the identification information of the terminal does not depend on a single IMEI, IMSI or MAC which is easy to be tampered, but is generated according to the application identifier of the application installed on the terminal. For different terminals, if a counterfeiter wants to tamper the identification information of the terminal, the application on the terminal needs to be installed or uninstalled, and compared with a simple mode of modifying a machine identification code in the traditional technology, the time consumption is more, so that the terminal is more inconvenient to forge, and therefore, in an application scene of counting the number of terminals based on the identification information, statistical data can be effectively prevented from being forged by lawless persons.

In the execution process of the method for generating the terminal identification information, the input parameters are all received through the external input interface 1001, transferred to the memory 1003 for buffering, and then input into the processor 1002 for processing, and the processed result data is buffered in the memory 1003 for subsequent processing, or transferred to the output interface 1004 for outputting.
