Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art without creative labor it is obtained it is all its
His embodiment, shall fall within the protection scope of the present invention.
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be further explained below with reference to the attached drawings and specific examples, but not as the limitation of the invention.
Based on the above-mentioned problems in the prior art, the present invention provides a kind of protection of intelligent algorithm model file
Method, model file and application intelligent algorithm in a local intelligent equipment including an intelligent algorithm handle number
According to application program, as shown in Figure 1, further comprising the steps of:
Step S1, is encrypted model file, forms an encryption file；
Step S2 carries out random division processing to encryption file, generates multiple sub- encryption files；
Step S3 encrypts the corresponding source code subfile of file generated according to every height respectively；
Step S4, by institute's source code subfile compiling link into application program.
Specifically, in specific embodiments of the present invention, a kind of model file of intelligent algorithm is embedded in local intelligent
In equipment, preset application program is handled data using above-mentioned intelligent algorithm in equipment.In order to protect above-mentioned people
The model file of work intelligent algorithm is not easy to crack and usurp, firstly, model file is encrypted to form an encryption file；
Then, random division is carried out into multiple sub- encryption files to encryption file；Further, file life is encrypted according to every height respectively
At corresponding source code subfile, wherein source code subfile can be C file perhaps C++ file or assembling file；Most
Afterwards, by institute's source code subfile compiling link into application program.
In preferred embodiment of the invention, in step S1, using preset Encryption Algorithm, using encryption key to model
File is encrypted, and forms encryption file.
Specifically, the basic process of data encryption be exactly to the file or data that were originally plaintext by certain algorithm at
Reason, becomes one section of unreadable code, commonly referred to as " ciphertext ", show that it can only after inputting corresponding key could
Original content is shown, approach in this way achievees the purpose that protect data not stolen, read by juridical-person.Encryption Algorithm is logical
Often it is divided into two major classes: " symmetrical expression " and " asymmetric ".
In a preferred embodiment of the invention, using symmetry encryption technology, that is, encrypts and decrypt using same close
Key, normally referred to as " SessionKey " this encryption technology are widely adopted now, and the DES as used by U.S. government adds
Data Encryption Standard is exactly a kind of typical " symmetrical expression " enciphered method, its SessionKey length is 56bits.
Model file is encrypted using above-mentioned symmetry encryption technology, forms encryption file.
Further, each source code subfile includes module control head and a character array；Wherein, module controls head
In include for deriving the information of Encryption Algorithm and encryption key, encrypting the total length of file, sub- encryption file in encryption file
In initial position, sub- encryption file size and son encryption file address；Character array is the text of son encryption file
Information.
In preferred embodiment of the invention, in step S4, by institute's source code subfile compiling link to application program
In after, each source code subfile is scattered in the different location of application program at random.
Specifically, institute's source code subfile is compiled into a file destination, it is right when carrying out link generation application program
The file destination list progress of incoming linker is randomly ordered, to upset position of each file destination in listed files, from
And realize in the application program of generation, each source code subfile is scattered in the different location of application program at random.
It should be noted that the file destination of other modules in above-mentioned list comprising application program.
In preferred embodiment of the invention, as shown in Fig. 2, when application program is needed using model file, under execution
State decryption step:

Step A3 solves encryption file according to the cipher mode that encryption file is encrypted in step S1
It is close, it obtains model file and exports.
Specifically, it in above-described embodiment, before application program needs calling model file, needs first in the application,
Head is controlled according to the module that whole source code subfiles are found in the address of sub- encryption file；Then, it is controlled in head according to module
Institute's source code subfile split is formed encryption file by initial position of the son encryption file in encryption file；Finally, due to
Using using symmetry encryption technology, can according in step S1 to the cipher mode that is encrypted of encryption file and use
In the information for deriving Encryption Algorithm and encryption key, encryption file is decrypted, model file is obtained and exports.
In preferred embodiment of the invention, as shown in figure 3, step A2 is specifically included:
Step A21 controls head according to module, extracts the content of the character array in corresponding source code subfile respectively；
Step A22, according to the content for extracting all character arrays, split forms encryption file.
Specifically, in above-described embodiment, head is first controlled according to module, respectively corresponding source code of extraction module control
The content of character array in file；Again file will be being encrypted according to the content and son encryption file of extracting all character arrays
In initial position, by sub- encryption file split formed encryption file.
In preferred embodiment of the invention, as shown in figure 4, step A3 is specifically included:
Step A31 controls head according to module and the Encryption Algorithm used in step S1 and encryption key is calculated；
Step A32 is decrypted encryption file using the Encryption Algorithm and encryption key being calculated, obtains model
File simultaneously exports.
Specifically, it in above-described embodiment, is first calculated in step S1 according to module control head and model file is added
Encryption Algorithm employed in close treatment process and encryption key；Again using the Encryption Algorithm and encryption key being calculated
Encryption file is decrypted, model file is obtained and exports.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
