Description

Method and system for automatically loading parameters, server side server and client side server

Technical Field

The present invention relates to information technology, and in particular, to a method and a system for automatically loading parameters, and a server and a client server thereof.

Background

Since the process of manually inputting information is cumbersome and error-prone, it is gradually replaced by automatic loading information technology. Existing ways to automatically load information are to scan a barcode (e.g., patent TWI 600492), install a profile, and image recognition (e.g., patent CN111882332 a). However, the scanning of the bar code requires additional bar code manufacturing, installation of a bar code scanner (or an electronic device with a camera lens) and connection to a network, and is not suitable for an environment where an external network cannot be connected or the electronic device with the camera lens cannot be used; the installation of the setting file has the problems of complicated operation and easy disclosure; image recognition is easy to distinguish errors, and the required operation resources are huge.

Detailed Description

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures and/or components have not been described in detail so as not to obscure the present invention.

Referring to fig. 1 and 2, a system 1 for automatically loading parameters (hereinafter referred to as system 1) according to an embodiment of the present invention may perform a method for automatically loading parameters (hereinafter referred to as loading method) according to an embodiment of the present invention, so as to remotely assist in automatically loading parameters into a health diagnosis system of a linear driving device, so that the health diagnosis system may operate according to the loaded parameters.

The system 1 comprises a server 2, the server 2 comprising a processor 21 and a memory 22 accessible by the processor 21. The processor 21 may be operatively programmed to include, for example and without limitation, a data sink 23, an encryption encoder 24, and an image encoder 25, the encryption encoder 24 being in communication with the image encoder 25. The memory 22 may be operatively programmed to include, for example and without limitation, a database 26 and a database 27, the data sink 23 and the encryption encoder 24 may be in communication with the database 26, and the image encoder 25 may be in communication with the database 27.

The system 1 further comprises a client server 3. The client server 3 may be part of a health diagnostic system or a machine control system. The client server 3 comprises a processor 31 and a memory 32. The processor 31 may be operatively programmed to include, for example and without limitation, an image decoder 33, a decryption decoder 34, and a parameter loader 35, the decryption decoder 34 being in communication with the image decoder 33 and the parameter loader 35, respectively. The memory 32 may be operatively programmed to include, for example and without limitation, a database 36 and a database 37, the image decoder 33 may be in communication with the database 36, and the decryption decoder 34 and parameter loader 35 may be in communication with the database 37. The client server 3 further includes a user interface 38 that communicates with the parameter loader 35 and the database 37. Database 37 may, for example and without limitation, store various software such as, but not limited to, diagnostic software including a health diagnostic system, and the diagnostic software provides user interface 38 as described above, so that the client-side algorithm of the diagnostic software may link user interface 38.

The loading method is exemplarily described below. The loading method comprises the following steps.

First, in step S11, the data collector 23 of the server 2 collects the information to be loaded and stores the information in the database 26. The information to be loaded is a set of data sequences including a set of plaintext codes and a set of ciphertext codes. The content of the set of codes is non-confidential data that allows the client to see, including a plurality of specification parameters and a plurality of specification indexes corresponding to the specification parameters, and the specification indexes point to a plurality of fields 381 to be loaded on the user interface 38, as shown in fig. 4; the set of passwords is confidential data that is not visible to the client, and includes a plurality of algorithm parameters. For example, a graphic illustration 41 of an engineering drawing 4 of a ball screw to be provided to a client as shown in fig. 3, this graphic illustration 41 includes a plurality of gauge items 42 and gauge content 43 of each gauge item 42. In this example, when the contents of the multiple specification requirement areas 44 of the graphic illustration 41 need to be input to the user interface 38, the staff on the server side can obtain the multiple specification items 42 and the specification contents 43 thereof in the specification requirement areas 44 through the data collector 23 by the central control database (not shown) connected with the server side server 2; in addition, when the service side is required to provide algorithm parameters (such as, but not limited to, poisson's ratio of materials, material density and dental model coefficients) to the client side algorithm of the diagnostic software, the service side staff can also obtain the algorithm parameters from the central control database through the data collector 23. The data assembler 23 then assembles the retrieved data into a set of JSON (JavaScript Object Notation) data formatted data sequences comprising a set of cleartext codes comprising the retrieved various specification items 42 (i.e., specification indexes) and their specification contents 43 (i.e., specification parameters) and a set of secret codes comprising the retrieved algorithm parameters and stores the data sequences in the database 26.

Next, in step S12, the encryption encoder 24 may obtain the information to be loaded from the database 26, and encrypt the information to be loaded into hidden information according to a first key. Specifically, the encryption encoder 24 first encrypts the set of passwords for the information to be loaded, such as, but not limited to, symmetric encryption, to form a set of scrambling codes; then, the set of clear codes and the set of scrambling codes are converted into a binary first bit code sequence as the hidden information.

Then, the image encoder 25 can obtain the hidden information from the encryption encoder 24 in step S13, and obtain a to-be-encrypted file containing the engineering drawing 4 from the database 27, and then further write the hidden information into the pixels of the engineering drawing 4 in a reversible information hiding procedure in step S14 to generate an encrypted file. Describing the manner of writing the hidden information into the pixels of the engineering drawing 4 by taking the example of the first bit code sequence with the hidden information as binary system, firstly converting the pixel values of the engineering drawing 4 into a second bit code sequence with binary system; the first bit code sequence is then added to the second bit code sequences of fig. 4 to produce the encrypted file. The reversible information hiding procedure can be, for example, but not limited to, using least significant bit type visual information hiding technique, most significant bit type visual information hiding technique, fast fourier transform hiding technique or discrete wavelet transform hiding technique. At this time, the information to be loaded is hidden and entrained in the engineering drawing of the encrypted file, so that the engineering drawing of the encrypted file is almost the same as the engineering drawing of fig. 4, and the difference cannot be recognized by naked eyes. The archive format of the file to be encrypted may be, for example, but not limited to, a file (such as, but not limited to, PDF) or an image file (such as, but not limited to, JPG or PNG). The archive format of the encrypted archive may be, for example, but not limited to, a file archive (e.g., but not limited to, PDF) or an image archive (e.g., but not limited to, JPG or PNG).

After the encrypted file is generated, the server 2 may export or export the encrypted file in step S15, and the encrypted file may be transmitted to the client, for example, but not limited to, through an external network, or provided to the client by being stored in a storage medium.

After the server 2 exports or exports the encrypted file, the client 3 loads the encrypted file in step S16, and then the image decoder 33 retrieves the hidden information from the engineering drawing of the encrypted file, i.e. interprets the set of clear codes and the set of messy codes from the encrypted file, in step S17, with a pixel decoding procedure. The engineering drawing of the encrypted file is retrieved with the hidden information and restored to the engineering drawing 4 and stored in the database 36.

Next, the decryption decoder 34 may obtain a key (i.e. the second key) corresponding to the first key from the database 37 in step S18, and obtain the hidden information from the image decoder 33, and then decrypt the hidden information into the information to be loaded in step S19 using the second key, that is, decrypt the set of scrambling codes into the set of scrambling codes using the second key. It should be noted that, in the symmetric encryption manner, the second key is the same as the first key, and if the asymmetric encryption manner is used, the second key and the first key have a set of public key and private key respectively, wherein the symmetric encryption and the asymmetric encryption can refer to the encryption technology of the existing cryptography, which is not described herein.

Finally, the parameter loader 35 may obtain the set of specifications from the decryption decoder 34 in step S20, and then automatically load the specification parameters corresponding to the specification indexes into the corresponding columns 381 to be loaded in the user interface 38 according to different specification indexes in the set of specifications, as shown in fig. 5. In step S21, the parameter loader 35 may also obtain the set of secret codes from the decryption decoder 34, and then automatically load a plurality of algorithm parameters in the set of secret codes into the client algorithm of the health diagnosis system or the machine control system.

In summary, the present invention can more efficiently and accurately complete the setting of the health diagnosis system (or other systems) by automatically loading parameters into the user interface 38, and save the manpower consumption; and may facilitate the start-up of the health diagnostic system (or other system) by automatically loading parameters into the algorithm. The staff of the client simply loads the encrypted file provided by the server into the client server 3, and the client server 3 automatically completes setting of parameters required by the health diagnosis system (or other systems), so that time and cost for additionally installing other equipment (such as but not limited to a bar code scanner) can be saved, and installation time and labor for installing a complex setting file of a program can be saved.

On the other hand, various non-confidential parameters and various confidential parameters which need to be set by the client are hidden and entrained in the engineering drawing 4 originally scheduled to be provided for the client by a reversible information hiding technology at the server in advance, and the engineering drawing of the encrypted file carrying hidden information is visually indistinct from the engineering drawing 4, so that the confidential information can obtain a confidential effect.

Also, since the key required for decryption is pre-stored in the database 37 of the client server 3, the encrypted file described above must be decrypted at the client server 3. In other words, if the encrypted file is not decrypted on the client server 3, the encrypted file cannot be successfully decrypted without a key, thereby ensuring information security.

In addition, the server 2 can complete hidden data entrainment in the file to and from the client under the internal independent network environment, and the client 3 can also complete parameter setting automatically under the internal independent network environment, so the system and loading method of the invention can still work under the condition that the server 2 or the client 3 cannot be connected with an external network.

Although the present invention is disclosed in the above embodiments, the present invention is not limited thereto. The present invention is not limited to the above-described embodiments, but is capable of modification, variation and combination of embodiments without departing from the spirit and scope of the present invention.
