DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for automatically loading parameters according to the present invention will be described in detail below with reference to the drawings. Note that the present invention is not limited to each embodiment.

A system 1 for automatically loading parameters (hereinafter abbreviated as system 1) according to an embodiment of the present invention is a method for automatically loading parameters (hereinafter abbreviated as loading method) according to an embodiment of the present invention. remotely assists in automatically loading parameters into the linear transmission medical examination system, and causes the medical examination system to operate based on these loaded parameters. The loading method according to an embodiment of the present invention also assists in automatically loading parameters into a machine control system and operating based on these loaded parameters (see FIGS. 1 and 2).

The system 1 includes a service end server 2 that includes a processor 21 and a storage 22 that the processor 21 accesses. The processor 21 includes, for example, a data assembler 23, an encryption encoder 24, and an image encoder 25, although the processor 21 is not limited in terms of operation, and the encryption encoder 24 is configured to communicate with the image encoder 25. Although the storage 22 is not limited in terms of operation, it is configured to include, for example, a database 26 and a database 27, a data assembler 23 and an encryption encoder 24 communicating with the database 26, and an image encoder 25 communicating with the database 27.

The system 1 further includes a client server 3. The client server 3 is a part of a medical examination system or a mechanical device control system. The client server 3 includes a processor 31 and a storage 32. The processor 31 includes, for example, a video decoder 33, a decoding decoder 34, and a parameter loader 35, although the processor 31 is not limited in terms of operation, and the decoding decoder 34 is configured to communicate with the video decoder 33 and the parameter loader 35, respectively. There is. Although the storage 32 is not operationally limited, it is configured to include, for example, a database 36 and a database 37, with the video decoder 33 communicating with the database 36, and the decoding decoder 34 and parameter loader 35 communicating with the database 37.
Client server 3 further includes a user interface 38 that communicates with parameter loader 35 and database 37 . The database 37 may store, for example, but not limited to, different software. These software include, but are not limited to, for example, diagnostic software of a medical examination system, and the diagnostic software provides the user interface 38 described above, so that client algorithms of the diagnostic software can be linked with the user interface 38.

The loading method will be exemplified below. This loading method includes the following steps.
First, in step S11, the data assembler 23 of the service end server 2 assembles the information to be loaded and stores it in the database 26. The information to be loaded is a set of data sequences, including a set of plain code and a set of ciphers. The content of the set of plain code is non-confidential data that the client is authorized to view, and includes a plurality of specification parameters and a plurality of specification indices corresponding to these specification parameters. As shown in FIG. 4, these specification indexes point to a plurality of loading fields 381 in the user interface 38. The set of ciphers prevents clients from seeing sensitive data and includes multiple algorithm parameters.
To give an example, a drawing explanation 41 regarding a design drawing 4 of a ball screw provided to a client shown in FIG. 3 includes a plurality of specification items 42 and specification contents 43 of each specification item 42. In this example, when inputting the contents of the plurality of specification requirement areas 44 of the drawing description 41 into the user interface 38, the service end worker uses the data assembler 23 to input the contents of the central control database to which the service end server 2 is connected. (not shown), a plurality of specification items 42 in the specification requirement area 44 and their specification contents 43 are acquired. Additionally, if the service end provides algorithm parameters (for example, but not limited to, Poisson's ratio of the ball screw material, material density, and tooth profile coefficient) to the client algorithm of the diagnostic software, the service end operator may also use the data assembler 23 to Retrieved from central control database. Thereafter, the data assembler 23 assembles the acquired data into a data sequence in the JSON (JavaScript Object Notation) data format and stores it in the database 26, and this data sequence is used to assemble the various acquired specification items 42 (i.e. A set of plain codes made up of a specification index) and its specification contents 43 (i.e. specification parameters) and a set of ciphers made up of obtained algorithm parameters.

Subsequently, in step S12, the encryption encoder 24 obtains the information to be loaded from the database 26, and encrypts and encodes the information to be loaded into hidden information based on the first secret key. Specifically, the encryption encoder 24 first encrypts the set of codes of the information to be loaded to form a set of garbled characters using a common key encryption method, although the encryption encoder 24 is not limited thereto. Thereafter, the one set of plain codes and the one set of garbled characters are converted into a binary first byte code string to be used as the above-mentioned hidden information.

Thereafter, in step S13, the image encoder 25 obtains hidden information using the encryption encoder 24, and obtains a file to be encrypted including the blueprint 4 from the database 27. Next, in step S14, hidden information is written so as to be hidden in the pixels of the blueprint 4 by a reversible information hiding process, and an encrypted file is generated.
Using an example in which the hidden information is the first bytecode string of binary numbers, a method for writing the hidden information so as to hide it in the pixels of the blueprint 4 will be described. First, a plurality of pixel values in the blueprint 4 are each converted into a binary second bytecode string. Thereafter, the first bytecode string is added to the plurality of second bytecode strings in the blueprint 4 to generate the above-mentioned encrypted file. The reversible information hiding process may utilize, but is not limited to, a least significant bit visual information hiding technique, a most significant bit visual information hiding technique, a fast Fourier transform hiding technique, or a discrete wavelet transform hiding technique. At this time, the information to be loaded is hidden in the design drawing of the encrypted file, so that the design drawing of the encrypted file and the design drawing 4 are substantially the same, and the difference cannot be discerned with the naked eye. The file format of the file to be encrypted is not limited, but may be, for example, a document file (eg, PDF, although not limited) or an image file (eg, JPG or PNG, although not limited). The file format of the encrypted file is not limited, but may be, for example, a document file (eg, PDF, although not limited) or an image file (eg, JPG or PNG, although not limited).

After generating the encrypted file, the service end server 2 exports or outputs the encrypted file in step S15. This encrypted file may be provided to the client by, for example, but not limited to, by transmitting it to the client via an external network or by storing it in a storage medium.

After the service end server 2 exports or outputs this encrypted file, the client server 3 loads the encrypted file in step S16. Thereafter, the video decoder 33 captures hidden information from the blueprint of the encrypted file through a pixel decoding process in step S17. That is, the one set of plain codes and the one set of garbled characters are decoded from the encrypted file. After capturing the hidden information from the blueprint of the encrypted file, it is recovered as the blueprint 4 described above and stored in the database 36.

Subsequently, in step S18, the decryption decoder 34 obtains the secret key (ie, the second secret key) corresponding to the first secret key from the database 37, and the video decoder 33 obtains the hidden information. Then, in step S19, the second private key is used to decrypt the information to be loaded with hidden information, that is, the second private key is used to decrypt the one set of garbled characters into the one set of codes. do. By the way, in the common key cryptosystem, the second secret key is the same as the first secret key, and when using the non-symmetric key cryptosystem, the second secret key and the first secret key are one set of public key and private key. They each have The common key cryptography and the non-symmetric key cryptography refer to conventional cryptographic encryption techniques, so their explanations will be omitted.

Finally, in step S20, the parameter loader 35 acquires the set of plain codes by the decoding decoder 34, and then calculates the specification parameters to which each specification index corresponds based on the different specification indexes of the set of plain codes. automatically into the corresponding loading field 381 of the user interface 38 (see FIG. 5). Further, in step S21, the parameter loader 35 automatically transfers many algorithm parameters of the set of codes to the client algorithm of the medical examination system or the mechanical device control system after acquiring the set of codes using the decryption decoder 34. Load into.

Taken together, the present invention allows the configuration of a medical examination system (or other system) to be completed more efficiently and accurately by automatically loading parameters into the user interface 38, thereby saving effort. Helps start up a health diagnostic system (or other system) by automatically loading parameters into an algorithm. The client worker can easily load the encrypted file provided to the service end into the client server 3, and the client server 3 can automatically complete the setting of the necessary parameters for the health examination system (or other system). This saves the time and cost of separately installing other equipment (eg, but not limited to, a barcode scanner), and also saves the time and effort of installing configuration files, which are a complex process.

On the other hand, the service end uses a reversible information hiding technique in advance to hide various non-confidential parameters and various confidential parameters of settings necessary for the client in the blueprint 4 that is originally scheduled to be provided to the client. The blueprint of the encrypted file that hides the hidden information has no visual difference from Blueprint 4, so it has the effect of keeping confidential information secret.

Further, since the private key necessary for decryption is stored in advance in the database 37 of the client server 3, the above-mentioned encrypted file needs to be decrypted on the client server 3. In other words, unless the encrypted file is decrypted on the client server 3, it cannot be decrypted because there is no private key, so the security of the information is ensured.

In addition, the service end server 2 hides data in document files exchanged with existing clients in an internal independent network environment, and the client server 3 also automatically completes parameter settings in an internal independent network environment. Therefore, the system and loading method according to the present invention operate even in a situation where the service end server 2 or the client server 3 cannot connect to an external network.

The above description is for illustrating the present invention, and should not be construed to limit the invention described in the claims or to restrict its scope. Furthermore, it goes without saying that the configuration of each part of the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the technical scope of the claims.
