Fig. 2 is please referred to, Fig. 2 is a kind of flow chart of data guard method provided in an embodiment of the present invention, the method packet
Include following steps：
Step S110：The U3D game installation kits of acquisition are parsed, the corresponding U3D of the U3D game installation kit is obtained
The current version number of engine.
In order to U3D play installation kit in executable file protect, prevent unauthorized person to its program code into
Row is distorted, so obtain U3D game installation kits to be installed first, i.e. APK (AndroidPackage, Android installation kit),
The U3D game installation kits of acquisition are parsed, to obtain the current version of the corresponding U3D engines of the U3D game installation kit
This number.
Specifically, U3D game installation kits are solved by the resolver file in the U3D of acquisition game installation kits
Analysis obtains the current version number of the corresponding U3D engines of the U3D game installation kit.
Wherein, resolver file refers to libunity.so files and libmono.so files, and libunity.so files are
The core library tool of U3D provides various functions realization, and libmono.so files are the core libraries of U3D, in android system
The environment for executing DLL (Dynamic Link Library, application program are expanded) file is provided.
That is, being parsed using resolver file, the version number of U3D engines is obtained, U3D engines are each for developing
Kind is played, that is, also different with the U3D game that different editions are developed, i.e. U3D game packages difference.
Step S120：An object run code mapping table is generated according to preset rules.
Operation code mapping table refers to opcode tables, and opcode refers to operation code, for describing in machine language instruction, is specified
Execute the machine code of certain operation, it can be understood as be the file that U3D compiles out, be a kind of intermediate language, be similar to word
Code is saved, bytecode can make an appointment operation rules, such as a+b=c, can be by using ADD a b and MOV c two instruction catalogues of a
Show.And all instructions is all by binary representation in a computer, therefore ADD here and MOV have pair in a computer
The numerical value answered indicates, for example ADD indicates that MOV is indicated with 02 with 01, then including ADD-01, MOV-02 in opcode tables
Such mapping relations.
Above-mentioned preset rules can be voluntarily defined with user, for example, for defined ADD-88, MOV- in advance
45, then it is 01-88 according to mapping relations, 02-45 generates object run code mapping table.
Alternatively, first according to preset rules generate an operation code mapping table, based on the operation code mapping table be generated in advance
Master operation code mapping table generate an object run code mapping table.
Master operation code mapping table is generated in advance and included in U3D game installation kits, is installed so playing to U3D
Packet can get master operation code mapping table after being parsed, for example, the mapping relations that it is instructed in master operation code mapping table
For ADD-01, MOV-02, then an operation code mapping table is generated at random according to customized preset rules, such as ADD-88, MOV-45,
So the mapping relations in the object run code mapping table of generation are 01-88,02-45.
Step S130：The executable file that corresponding version is selected according to the current version number of the U3D engines, according to described
Object run code mapping table maps the executable file, the target executable file after being mapped.
Since the U3D engines of each version correspond to the executable file of different editions, executable file can be regarded as U3D
The binary system of engine output executes file, namely for the executable file for generating U3D game installation kits, to executable file
In all parts opcode mapped according to object run code mapping table, for example, the portions opcode in executable file
ADD-01 in point, then mapped according to the 01-88 in the object run code mapping table of above-mentioned generation, that is, by executable text
Opcode partial replacements in part are 01-88.
Step S140：Executable file in U3D game installation kits is replaced with into the target executable file, is obtained
Obtain target U3D game installation kits.
Executable file in original U3D game installation kits is replaced with into the target executable file after being mapped, from
And target U3D game installation kits are obtained, to which the executable file in target U3D game installation kits has been redesigned
, so the safety and reliability for U3D game installation kits, improves the safety of U3D game installation kits.
Specifically, as an implementation, executable file includes dll file and resolver file, according to the U3D
The executable file of the corresponding version of current version number selection of engine, according to the object run code mapping table to described executable
File is mapped, the target executable file after being mapped, including：
The dll file in U3D game installation kits is mapped according to the object run code mapping table, is reflected
Target dll file after penetrating；It is compiled with the current version number in advance according to the selection of the current version number of the U3D engines
Resolver file in the U3D game installation kits of corresponding version is mapped according to the object run code mapping table, is obtained
Target resolver file after must mapping.
Wherein, the dll file in U3D game installation kits is traversed, to each operation in the dll file
Code part is mapped according to the object run code mapping table, the target dll file after being mapped.Namely for each
The parts opcode in dll file are mapped according to object run code mapping table so that in the above described manner in dll file
Mapping relations in the parts opcode all replace with the mapping relations in object run code mapping table.
According to the current version number of the U3D engines, the resolver file of compiled various versions in advance is selected (i.e.
Libmono.so files and libunity.so files), and the parts opcode in resolver file are reflected according to object run code
Mapping relations in firing table are mapped.
Then the dll file U3D played in installation kit replaces with the target dll file, and by the U3D
Resolver file in game installation kit replaces with the target resolver file, obtains target U3D game installation kits, as a result,
The mapping relations in the operation code mapping table in executable file in target U3D game installation kits have been replaced by target behaviour
Make the mapping relations in code mapping table so that first according to the mapping relations of user oneself definition when generating U3D game installation kits
Executable file is generated, then so that the U3D game installation kits that U3D engines generate are not easy to be cracked, improves U3D game installations
The safety of packet.
Fig. 3 is please referred to, Fig. 3 is a kind of structure diagram of data protecting device 200 provided in an embodiment of the present invention, the dress
Set including：

Resolver file in the U3D game installation kits of the advance compiled version corresponding with the current version number of this number selection
It is mapped according to the object run code mapping table, the target resolver file after being mapped；The file replacement module
240, replace with the target dll file specifically for the dll file in installation kit that the U3D plays, and by the U3D
Resolver file in game installation kit replaces with the target resolver file, obtains target U3D game installation kits.
Further, the dll file map unit, be specifically used for the U3D play installation kit in dll file into
Row traversal, each operation part in the dll file is mapped according to the object run code mapping table, is reflected
Target dll file after penetrating.
It is apparent to those skilled in the art that for convenience and simplicity of description, the device of foregoing description
Specific work process, can refer to preceding method in corresponding process, no longer excessively repeat herein.
In conclusion a kind of data guard method of offer of the embodiment of the present invention and device, this method is first to the U3D of acquisition
