Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In describing embodiments of the present disclosure, the terms "include" and its derivatives should be interpreted as being inclusive, i.e., "including but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.
The neural network framework of the neural network model is divided into a static graph framework and a dynamic graph framework. When using the static graph framework, the graph structure of the network needs to be defined first. Therefore, the calculation graph is constructed during the first operation, and the calculation graph is not required to be constructed during the second operation, so that the operation speed is high.
The pre-training model is a model created to solve similar problems. When the similar problem is solved, the model does not need to be trained from the beginning, and the model can be directly retrained again based on the pre-training model so as to quickly obtain the corresponding inference model. Most open source pre-trained models are not usually encrypted, but the effect is not optimal. However, the open-source pre-trained model is not the best model for the industry. For the pre-training model with good effect, the general network structure is deep, the number of network parameters is huge, and massive data is needed for training. Therefore, producing a good pre-trained model consumes a lot of cost, including a lot of computing resources. If provided directly to the user, there is a possibility that the user is provided to his user for use, resulting in an unsafe pre-trained model.
In addition, the inference model obtained by training the pre-training model generally needs to be encrypted, and when the model performs inference, decryption operation is performed to generate a temporary plaintext model file to a disk, and then the temporary plaintext model file is loaded to a memory from the disk, so that model inference is completed. However, the cryptographic implementation for the inference model is relatively simple and the generated model file is at risk of "leakage". Furthermore, the inference model of this arrangement cannot support operations that a user wants to fine-tune using his own data.
In order to solve at least the above problems, according to an embodiment of the present disclosure, an improvement is proposed. In this approach, a computing device obtains a file of a machine learning model that includes a set of parameter values that are available for the machine learning model. The computing device then adjusts at least one parameter value of the set of parameter values based on a predetermined rule to obtain an adjusted file of the machine learning model. The computing device obtains an encrypted file of the machine learning model by encrypting the adjusted file of the machine learning model. By the method, the safety of the machine learning model can be effectively ensured, and the model is prevented from being acquired by other users.
Fig. 1 illustrates a schematic diagram of an environment 100 in which various embodiments of the present disclosure can be implemented. The example environment 100 includes a computing device 104.
The computing device 104 can encrypt the file of the machine learning model 102 to generate an encrypted file of the machine learning model 110 or decrypt the encrypted file of the generated machine learning model 110 to obtain the file of the machine learning model 102.
The file 102 of the machine learning model is a file that stores the machine learning model. Within this document is included a program of machine learning models and a set of parameter values for the parameters of the machine learning models. In some embodiments, the machine learning model is a pre-trained model. In some embodiments, the machine learning model is an inference model. In some embodiments, the set of parameters are weight parameters. In some embodiments, the set of parameters may be any parameters for a machine learning model. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure.
FIG. 1 shows a computing device 104 receiving a file 102 of a machine learning model. For example, the computing device 104 receives the file 102 of the machine learning model from other computing devices or storage connected to the computing device 104. Fig. 1 shows that the computing device 104 receives the file 102 of the machine learning model is merely an example, and the computing device 104 may retrieve the file 102 of the machine learning model from its internal storage.
The computing device 104 adjusts at least one number of the set of parameters in the file 102 of machine learning models to generate adjusted parameter values 106 such that an adjusted file of machine learning models is formed that includes the adjusted parameter values 106.
The computing device 104 then performs an encryption operation on the adjusted file of the machine learning model to generate an encrypted file 110 of the machine learning model. In some embodiments, the encryption algorithm that encrypts the adapted file of the machine learning model is a symmetric encryption algorithm. In some embodiments, the encryption algorithm that encrypts the adapted file of the machine learning model is an asymmetric encryption algorithm. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure. The adjusted file of the machine learning model may be encrypted by one skilled in the art using any suitable encryption algorithm.
The computing device 104 may also decrypt the encrypted file 110 of the machine learning model to obtain a decrypted file of the machine learning model, the decrypted file being an adjusted file. After obtaining the encrypted file 110 of the machine learning model, the computing device 104 decrypts the file using a decryption algorithm corresponding to the encryption algorithm of the encrypted file that generated the machine learning model. Such as a symmetric decryption algorithm or an asymmetric decryption algorithm corresponding to a symmetric encryption algorithm/an asymmetric encryption algorithm.
The computing device 104 then performs a recovery operation on some parameter values in the decrypted file of the neural network model. The computing device 104 selects the at least one parameter value in the same manner as the parameter value was selected when generating the encrypted file 110 of the machine learning model. A recovery operation is then performed on the at least one parameter value, as opposed to when the parameter was adjusted, to obtain a recovered parameter value 108. For example, if the parameter value is increased by a predetermined value when the parameter value is adjusted, the predetermined value is decreased when the recovery operation is performed. If the parameter value is adjusted by increasing the parameter by a predetermined factor, the parameter is reduced by the predetermined factor in the recovery operation. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure.
After the adjusted parameter values are restored, a file 102 of the machine learning model is generated for use by the user.
The encryption and decryption operations performed by the computing device 104 on the machine learning model file are shown in fig. 1, which is an example only and not a specific limitation of the present disclosure. Those skilled in the art may implement the above-described functions on different computing devices as desired. In some embodiments, the computing device that encrypts the file of machine learning models 102 and the computing device that decrypts the encrypted machine learning model file 110 are two different computing devices.
In some implementations, the computing device 104 also determines the identification value of the encrypted file of the machine learning model after generating the encrypted file of the machine learning model 110. The identification value may be used to verify an encrypted file of the machine learning model to determine whether the file encrypted by the machine learning model was modified. In some embodiments, the identification value of the encrypted machine learning model file is determined using a Message Digest ("MD") algorithm, such as the MD5, MD4 algorithm. In some embodiments, the identification value may be determined using any suitable identification value generation method that can uniquely determine the encrypted machine learning model file. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure.
In some embodiments, the computing device also verifies the decrypted machine learning model file prior to decrypting the encrypted machine learning model file 110. The determination of whether the machine learning model has been altered is made, for example, using a comparison of the identification value obtained when the encrypted file 110 of the machine learning model was generated and the identification value recalculated for the encrypted file of the machine learning model. If so, the encrypted machine learning model file is not processed. If not, it is decrypted.
In some embodiments, the computing device 104 may, after obtaining the file 102 of the machine learning model, train it further with sample data to obtain an inference model. After obtaining the inference model, the inference model may be encrypted using a symmetric or asymmetric encryption algorithm, and then an identification value may be generated for the encrypted file that can be verified and stored at the head of the encrypted inference model file to facilitate verification of the encrypted inference model. Encrypted version information may also be stored in the header of the file. Upon obtaining the encrypted inference model, the identification value may be obtained from a file header to verify the inference model. And then decrypted using a decryption process that is the reverse of the encryption process.
By the method, the safety of the machine learning model can be effectively ensured, the encrypted model can be trained to obtain the encrypted model with updated parameters, and the safety and the accuracy of the model are improved.
Fig. 1 above illustrates a schematic diagram of an environment 100 in which various embodiments of the present disclosure can be implemented. A flow diagram of a method 200 for processing files of a machine learning model according to some embodiments of the present disclosure is described below in conjunction with fig. 2. Method 200 in fig. 2 is performed by computing device 104 in fig. 1 or any suitable computing device.
At block 202, a file of a machine learning model is obtained that includes a set of parameter values that are available for the machine learning model. For example, the computing device 104 obtains a file 102 of the machine learning model. The file 102 of the machine learning model includes a program of the machine learning model and a set of parameter values for parameters of the machine learning model. In some embodiments, the machine learning model is a pre-trained model. In some embodiments, the machine learning model is an inference model. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure.
At block 204, at least one parameter value in a set of parameter values is adjusted based on a predetermined rule to obtain an adjusted file of the machine learning model. For example, the computing device 104 adjusts at least one parameter value of a set of parameter values based on a predetermined rule to obtain an adjusted file of the machine learning model.
In some embodiments, the computing device 104 determines at least one parameter value from the set of parameter values based on an order of locations of the parameter values in the set of parameter values. For example, the 1 st and/or 3 rd parameter value in a set of parameter values is selected. The computing device 104 then adjusts the size of the at least one parameter value based on the predetermined rule. In one example, the predetermined rule is a obfuscation algorithm. The computing device 104 utilizes a hashing algorithm to adjust the size of the parameter values. In another example, the predetermined rule is to increase or decrease the parameter value by a predetermined value, or to enlarge/reduce by a predetermined factor. In some embodiments, each of the at least one parameter values is changed by the same amount. In some embodiments, each of the at least one parameter values is changed by a different magnitude. Alternatively or additionally, the predetermined rule is known to both encrypt and decrypt the file, upon decryption, the parameter values may be recovered based on the predetermined rule. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure. The size of the parameters can be adjusted as desired by those skilled in the art. By the method, the safety of the machine learning model file can be higher, and the file leakage is prevented.
In some embodiments, a suitable algorithm may be employed to select a parameter value of a set of parameter values to adjust, and then adjust the parameter value. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure. The skilled person may select the at least one parameter value using any suitable parameter value selection method as required.
At block 206, the adjusted file of the machine learning model is encrypted to obtain an encrypted file of the machine learning model. For example, the computing device 104 encrypts the adjusted file of the machine learning model to obtain an encrypted file 110 of the machine learning model.
In some embodiments, the adjusted file of the machine learning model is encrypted using a symmetric encryption algorithm or an asymmetric encryption algorithm. In some embodiments, the adapted file of the machine learning model may be encrypted using any suitable encryption algorithm. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure. By the method, the safety level of the file of the machine learning model can be improved, and the file is ensured not to be acquired by other users.
In some embodiments, based on the encrypted file of the machine learning model, an identification value of the encrypted file is generated for use in verifying the encrypted file. For example, the MD5 value of the encrypted file of the machine learning model is calculated using the MD5 algorithm, and then the MD5 value can be used to verify whether the encrypted file of the machine learning model has been modified. By the method, whether the encrypted file is modified or not can be quickly determined.
By the method, the safety of the machine learning model can be effectively ensured, and the model is prevented from being acquired by other users.
A flowchart of a method 200 for processing files of a machine learning model according to some embodiments of the present disclosure is described above in connection with fig. 2. A flow diagram of a method 300 for processing files of a machine learning model is described below in conjunction with FIG. 3. Method 300 in fig. 3 is performed by computing device 104 in fig. 1 or any suitable computing device.
Fig. 2 above describes the process of encrypting the file of the machine learning model, and fig. 3 below describes the process of decrypting the encrypted file of the machine learning model.
At block 302, an encrypted file of a machine learning model is obtained. For example, the computing device 104 obtains an encrypted file 110 of the machine learning model. In some embodiments, the encrypted file 110 of the machine learning model may be obtained by the computing device 104 from other computing devices. In some embodiments, the computing device 104 retrieves the encrypted file 110 of the machine learning model from its storage. The above examples are intended to be illustrative of the present disclosure, and are not intended to be limiting of the present disclosure.
At block 304, the encrypted file of the machine learning model is decrypted to obtain an adjusted file of the machine learning model, the adjusted file of the machine learning model including a set of parameter values. For example, the computing device 104 decrypts the encrypted file 110 of the machine learning model, the decrypted file being an adjusted file of the machine learning model, the adjusted file of the machine learning model including a set of parameter values.
In some embodiments, the computing device 104 obtains a first identification value corresponding to an encrypted file of the machine learning model. For example, a first identification value, such as an MD5 value, is obtained when the encrypted file is generated. The computing device 104 then generates a second identification value for the machine learning model encrypted file 110 from the machine learning model encrypted file 110. For example, re-process the encrypted file with the MD5 algorithm to generate a new MD5 value. The computing device 104 then compares the first identification value to the second identification value. If equal, indicating that the encrypted file has not been modified, the encrypted file 110 of the machine learning model is decrypted. If not, indicating that the encrypted file was modified, no operation is performed on the file. By the method, whether the encrypted file is modified or not can be quickly verified.
In some embodiments, the encrypted file of the machine learning model is decrypted using a symmetric decryption algorithm or an asymmetric decryption algorithm. Alternatively or additionally, the symmetric decryption algorithm or the asymmetric decryption algorithm corresponds to a symmetric encryption algorithm and an asymmetric encryption algorithm when encrypting the file. In this way, the security of the files of the machine learning model may be determined.
At block 306, a recovery operation is performed on at least one parameter value in the set of parameter values based on a predetermined rule to obtain a file of the machine learning model. For example, the computing device 104 performs a recovery operation on at least one parameter value in a set of parameter values based on a predetermined rule to obtain a file of the machine learning model.
In some embodiments, the computing device 104 determines at least one parameter value from the set of parameter values based on an order of locations of the parameter values in the set of parameter values. The parameter values are selected, for example, according to the same selection method as in encryption to find at least one parameter value that was modified in encryption. The computing device then performs a recovery operation on the at least one parameter value based on a predetermined rule. The predetermined rule corresponds to a rule at the time of encryption. Based on a predetermined rule, an operation reverse to the adjustment operation at the time of encryption is performed. For example, if a predetermined value is increased for a parameter value at the time of encryption, the predetermined value is decreased for the parameter at that time. By the method, the adjusted parameters can be quickly determined, and the data processing efficiency is improved.
In some embodiments, the computing device 104 may also train a machine learning model corresponding to a file of machine learning models with the sample data to obtain a target machine learning model. For example, when the machine learning model is a pre-training model, the inference model can be obtained by adopting sample training. The computing device 104 then determines a file of the target machine learning model. The file includes at least the programs and parameter values of the target machine learning model. The computing device 104 encrypts the file of the target machine learning model to generate an encrypted file of the target machine learning model. The computing device 104 then computes the encrypted file of the target machine learning model to generate an identification value of the encrypted file of the target machine learning model for use in verifying the encrypted file of the target machine learning model. For example, the MD5 value of the encrypted file is calculated. Alternatively or additionally, the security of the target machine learning model can be increased by adjusting parameters in the process of encrypting and decrypting the target machine learning model. By the method, the safety of the trained target machine learning model can be ensured.
In some embodiments, the computing device 104 encrypts the file of the target machine learning model using a symmetric encryption algorithm or an asymmetric encryption algorithm. By the method, the safety of the target machine learning model can be ensured.
In some embodiments, the computing device 104 may also decrypt the encrypted file of the target machine learning model, e.g., using a symmetric decryption algorithm or an asymmetric decryption algorithm. Alternatively or additionally, before decryption, a comparison is also required to verify whether the encrypted file has been modified based on the identification value generated when the encrypted file was generated and the identification value obtained by reprocessing the encrypted file of the target machine learning model. When the two identification values are the same, the encrypted file is not modified, and then the decryption operation is performed. Otherwise, the encrypted file is not operated.
By the method, the safety of the machine learning model can be effectively ensured, the encrypted model can be trained to obtain the encrypted model with updated parameters, and the safety and the accuracy of the model are improved.
A method 300 for processing files of a machine learning model is described above in connection with fig. 3. An example of a method 400 for processing a machine learning model file is described below in conjunction with FIG. 4. The data in method 400 in fig. 4 is performed by computing device 104 in fig. 1 or any suitable computing device.
In fig. 4, the file of the machine learning model is a file of a pre-trained model. At 402, the computing device 104 obtains a file of the pre-trained model. The computing device 104 then performs data content obfuscation processing on the model parameters in the file of the pre-trained model at 404. For example, the at least one model parameter value is sized such that the pre-trained model does not function properly when using the adjusted parameter value. The obfuscated file of the pre-trained model is then encrypted using a symmetric or asymmetric encryption algorithm at block 406. The encrypted pre-training model file is then subjected to a model verification process at block 408 to generate an identification value of the encrypted file of the pre-training model, which can be used to verify the encrypted file of the pre-training model. For example, the identification value is the MD5 value of the encrypted file of the pre-trained model. An encrypted file of the pre-trained model is then obtained at block 410.
The encrypted file of the pre-trained model may be decrypted as shown in fig. 4 using the reverse operation of the encryption process. After obtaining the encrypted file of the pre-trained model at block 410, then at block 408, a model check may be utilized to verify whether the encrypted file of the pre-trained model was modified. For example, the identification value obtained when the encrypted file of the pre-trained model is obtained is compared with the identification value recalculated using the encrypted file of the pre-trained model to verify whether the encrypted file of the pre-trained model has been modified. If so, the model is not processed. If not, a decryption operation is performed using a symmetric or asymmetric decryption algorithm at block 406. The adjusted parameter values in the decrypted file of the model are then data content defrobulated at block 402, i.e. the parameter values adjusted by the obfuscation process are restored to their original values. A file of the pre-trained model is then obtained.
After obtaining the file of the pre-trained model, the file of the pre-trained model may be trained to obtain a file of the inference model, as shown at block 412. The computing device 104 then encrypts the file of the inference model using a symmetric or asymmetric encryption algorithm at block 414. At block 416, the computing device 104 performs a model checking process on the encrypted file of the inference model, the process operable to generate an identification value for the encrypted file of the inference model, which may be used to check whether the encrypted file of the inference model is modified. For example, the MD5 value of the encrypted file that generated the inference model. An encrypted file of the inference model is then obtained at block 418. The encrypted files 410 of the training model and the encrypted files 418 of the inference model are then available to a deep learning framework 420.
The computing device 104 may also perform decryption on the encrypted inference model file, which is the reverse of the encryption process of the inference model file, i.e., perform verification first, and perform decryption after verification to obtain a usable inference model file.
By the method, the safety of the machine learning model can be effectively guaranteed, the encrypted model can be trained to obtain the encrypted model with updated parameters, and the safety and the accuracy of the model are improved.
