[0095] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0096] During the embroidery process of an embroidery machine, technicians first use embroidery software to design embroidery patterns and generate pattern files, and then the control system of the embroidery machine controls the actuator of the embroidery machine to embroider on the fabric according to the data in the pattern files. Among them, the embroidery files contain embroidery data such as stitch data and color change data. A complex pattern file may take two to three people 20 to 30 working days to complete. Therefore, the pattern file is crucial for an embroidery factory.

[0097] The file format of the existing pattern files is open, such as the DST format or the DSB format. That is, anyone who obtains the pattern file can parse and run it on an embroidery machine or a computer, enabling the embroidery machine to embroider colors on the fabric. Moreover, anyone can edit and modify the pattern file, resulting in poor security of the pattern file and being easily stolen and tampered with.

[0098] In view of this, the embodiments of this application use a first password to encrypt the pattern information to obtain pattern data, so as to improve the security of the pattern information. Moreover, a preset key is used to encrypt the first password to obtain first password data, and the first password data and the pattern data form a pattern file. In this way, when other users use the pattern information, they need to decrypt the first password data and the pattern data twice to obtain the pattern information, improving the security of the pattern file and avoiding the pattern file being stolen and tampered with.

[0099] The method for processing the pattern file provided by the embodiments of this application is applicable to an application scenario, such as Figure 1As shown in the figure, it includes: a first user terminal 101 and a second user terminal 102. Among them, the first user terminal 101 and the second user terminal 102 can be two different electronic devices respectively. The first user terminal 101 and the second user terminal 102 can be communicatively connected to realize the transmission of pattern files; alternatively, the pattern files are transported from the first user terminal 101 to the second user terminal 102 through a storage device such as a USB flash drive. The first user terminal 101 encrypts the pattern information according to the first password obtained from the first password data to obtain pattern data, and the pattern data and the first password data generate a pattern file; after the pattern file is transmitted to the second user terminal 102, the second user terminal 102 decrypts the first password data to obtain the first password; and decrypts the pattern data according to the first password to obtain the pattern information; finally, the pattern information is displayed on the second user terminal 102.

[0100] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0101] Refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for processing a pattern file provided by an embodiment of the present application. The method for processing the pattern file includes:

[0102] S201. Receive an open instruction for the pattern file.

[0103] In the embodiments of the present application, the execution subject can be a computer or the main control system of an embroidery machine. Optionally, the main control system of the embroidery machine can be implemented by software or by a combination of software and hardware.

[0104] Among them, the pattern file includes pattern data and first password data. The first password data is obtained by encrypting the first password with a preset key, and the pattern data is obtained by encrypting the pattern information with the first password. The pattern information is used to indicate the pattern embroidered by the embroidery machine.

[0105] The pattern information includes stitch data, color change data, etc. Each stitch point contains stitch information. Usually, the stitches are divided into flat stitches, jump stitches, gold piece switches, color changes, bead feeding, etc. The embroidery machine performs embroidery operations according to the stitches. A flat stitch means to drop the needle, a jump stitch means not to drop the needle, a gold piece open means that the gold piece device drops to prepare for bead feeding, and bead feeding means to eject the sequins. The embroidery machine has multiple needle bars and can embroider multiple colors of embroidery threads. When switching from one needle bar to another, it is called a color change.

[0106] Generally, technicians need to use pattern design software on a computer to design embroidery patterns. For example, use emCAD to design embroidery patterns and output pattern files in DHA format.

[0107] The user inputs an open instruction for the pattern file through the input devices of the computer, such as a keyboard and a mouse. Exemplarily, after selecting the pattern file, double-click the left button of the mouse to input an open instruction for the pattern file. Or, the user inputs an open instruction for the pattern file through the control panel of the embroidery machine, such as buttons or a touch screen, etc. The control device of the computer or the embroidery machine receives the open instruction for the pattern file through the input device.

[0108] S202. Decrypt the first password data with the preset key to obtain the first password.

[0109] Among them, the preset key is set in advance. For example, when the software for designing or opening pattern information is used for the first time, the user configures the preset key. The specific method for decrypting the first password data with the preset key is not limited. For example, those skilled in the art can use the preset key and the DES (Data Encryption Standard) algorithm to decrypt the first password data to obtain the first password.

[0110] The first password can be a pure digital password. For example, a nine-digit number; the first password can also be a combination of numbers and letters, and the embodiments of the present application do not limit this.

[0111] S203. Decrypt the pattern data according to the first password to obtain the pattern information.

[0112] For example, use the first password as the key to decrypt the pattern data to obtain the pattern information. The specific method for decrypting the pattern data is not limited. For example, the embodiments of the present application can use the first password as the key and the DES algorithm to decrypt the first password data to obtain the pattern information.

[0113] S204. Display the pattern information.

[0114] Display the pattern information on the display screen of the computer so that the user can modify and save the pattern information. Or display the pattern information on the embroidery machine so that the embroidery machine can control the actuator to embroider according to the pattern information.

[0115] The method for processing a pattern file provided by an embodiment of the present application, wherein the pattern file includes pattern data and first cipher data, the first cipher data is obtained by encrypting a first cipher with a preset key, and the pattern data is obtained by encrypting pattern information with the first cipher; after receiving an open instruction for the pattern file, decrypt the first cipher data with the preset key to obtain the first cipher; and decrypt the pattern data according to the first cipher to obtain pattern information; then display the pattern information on the user terminal. In this process, the user terminal needs to decrypt the first cipher data to obtain the first cipher and decrypt the pattern data according to the first cipher to obtain the pattern information, that is, double decryption is required to obtain the pattern information, which improves the security of the pattern file and prevents the pattern information from being randomly changed or stolen.

[0116] Based on the embodiment shown in Figure 2 , the following further elaborates on the method for processing a pattern file in conjunction with Figure 3 .

[0117] Figure 3 The flowchart of the method for processing a pattern file provided by another embodiment of the present application is shown. Please refer to Figure 3 . The method includes:

[0118] S301. Receive an open instruction for the pattern file.

[0119] It should be noted that the execution process of step S301 can refer to the execution process of S201, and will not be elaborated here.

[0120] S302. Decrypt the first cipher data with the preset key to obtain the first cipher.

[0121] It should be noted that the execution process of step S302 can refer to the execution process of S202, and will not be elaborated here.

[0122] S303. Read the local configuration file.

[0123] Among them, the local configuration file is a set of settings and files for the pattern design software to load the required environment for the user when the user first opens the pattern design software.

[0124] Generally, the local configuration file is stored in a preset location. When the user terminal finds the local configuration file at the preset location, it means that the local configuration file has been read, and then step S304 is executed; when the user terminal does not find the local configuration file at the preset location, it means that the local configuration file has not been read, and then step S308 is executed.

[0125] In some implementations, the local configuration file may be set in the following manner: receiving a second password input by a user, encrypting the second password with a preset key, and obtaining the local configuration file.

[0126] S304: Decrypt the local configuration file using the preset key to obtain a second password.

[0127] The preset key is pre-set when setting the local configuration file, for example, the key configured by the user when using or opening the pattern design software for the first time. The specific method of decrypting the second password data using the preset key is not limited. For example, those skilled in the art can use the preset key and the DES (Data Encryption Standard) algorithm to decrypt the local configuration file to obtain the second password.

[0128] The second password may be a pure numeric password, for example, eight digits; the second password may also be a combination of numbers and letters, which is not limited in the embodiments of the present application.

[0129] According to the first password and the second password, the pattern data is decrypted to obtain the pattern information. For example, there is a mapping relationship between the first password and the second password, and the decryption key is determined through the mapping relationship to decrypt the pattern data; for another example, by comparing whether the first password and the second password are the same, the key for decrypting the pattern data is determined. For details, refer to steps S305 to S306.

[0130] S305: Determine whether the first password is the same as the second password.

[0131] The first password and the second password are compared, and if every bit of the first password is the same as the second password, then the first password and the second password are determined to be the same. It can be understood that the first password and the second password have the same number of bits.

[0132] If the first password is the same as the second password, the judgment is "yes", indicating that the second password verification is successful, and step S306 is executed; if the first password is different from the second password, the judgment is "no", indicating that the second password verification fails, and step S308 is executed.

[0133] S306: Use the first password to decrypt the pattern data to obtain the pattern information.

[0134] This step can be understood as, when the second password is the same as the first password, that is, the second password of the user terminal is the same as the first password in the pattern file; or, when the third password input by the user is the same as the first password, the first password is used as a key to decrypt the pattern data and obtain the pattern information, that is, the pattern information is successfully opened so that the pattern information can be displayed on the user terminal.

[0135] Using the first password as the key, decrypt the pattern data to obtain the pattern information. The specific method for decrypting the pattern data is not limited. For example, in the embodiments of the present application, the first password can be used as the key and the DES algorithm can be used to decrypt the first password data to obtain the pattern information.

[0136] S307. Display the pattern information.

[0137] It should be noted that the execution process of step S307 can refer to the execution process of S204, and will not be elaborated here.

[0138] S308. Output the first prompt message.

[0139] When the second password is different from the first password, or when the local configuration file is not read, this step is executed. The first prompt message is used to indicate the password for inputting the pattern file, and the user can input the password for the pattern file according to the first indication message. Specifically, the first indication message can be a password input interface displayed on the display screen of the user terminal to indicate the user to input the password for the pattern file;

[0140] S309. Receive the third password input by the user.

[0141] The user can input the third password through an input device such as a keyboard, and thus receive the third password input by the user through the keyboard. Of course, the user can also connect an external input device to the user terminal, and when the user inputs the third password through the external input device, the user terminal can receive the third password.

[0142] The third password has the same number of digits as the first password. The third password can be only numbers, or a combination of numbers and letters, etc., which is not limited here.

[0143] S310. Determine whether the first password is the same as the third password.

[0144] Compare the first password and the third password. If each digit of the first password is the same as the third password, it is determined that the first password and the third password are the same.

[0145] If the first password is the same as the third password, that is, it is determined as "yes", indicating that the third password verification is successful, then execute step S306; if the first password is different from the third password, that is, it is determined as "no", indicating that the third password verification fails, then execute step S311.

[0146] S311. Output the first prompt message again until the third password input by the user is the same as the first password, or the number of times the user inputs the third password reaches the preset number of times.

[0147] This step can be understood as the processing step after the third password verification fails. In some possible implementation manners, when the first password is different from the third password, the first prompt message is output again until the third password input by the user is the same as the first password.

[0148] In other possible implementation manners, the first prompt message is output again until the number of times the user inputs the third password reaches a preset number of times, such as five times.

[0149] Optionally, when the number of times the user inputs the third password reaches the preset number of times, the method further includes outputting a second prompt message, and the second prompt message is used to indicate that the pattern file fails to be opened. Such a setting is beneficial to further improving the security of the pattern file and avoiding malicious password cracking.

[0150] The pattern file processing method provided by the embodiments of the present application obtains the second password through a local configuration file, and when the second password is the same as the first password, the first password is used to decrypt the pattern data to obtain pattern information; when the local configuration file is not read, by comparing the third password input by the user with the first password, when the third password is the same as the first password, the first password is used to decrypt the pattern data to obtain pattern information, that is, only when the password of the local configuration file is the same as the first password, or when the password input by the user is the same as the first password, can the pattern data be decrypted to obtain pattern information, which improves the security of the pattern file and avoids the pattern file from being stolen or tampered with at will.

[0151] It can be understood that in the embodiments of the present application, a pattern file can be generated on one user terminal and opened and used on another user terminal. For example, the pattern designed by Company A is supplied to Company B for use; or, a pattern file is generated on one user terminal and opened or used on the same user terminal. For example, after Company A designs a pattern file, the pattern file is modified again. Before opening or using the pattern file, the pattern file needs to be generated first.

[0152] The following Figure 4 , further details the generation of the pattern file. Among them, Figure 4 is a schematic flowchart of the pattern file processing method provided by another embodiment of the present application. Please refer to Figure 4 , this method includes:

[0153] S401. Receive the first password input by the user.

[0154] The user can input the first password through an input device such as a keyboard, so that the user terminal receives the first password input by the user through the keyboard. Of course, the user can also connect an external input device to the user terminal. When the user inputs the first password through the external input device, the user terminal can receive the first password.

[0155] S402. Encrypt the first password using the preset key to obtain the first password data.

[0156] The preset key is set in advance. For example, when the computer is used for the first time or the pattern design software is opened, the key configured by the user. The specific method for encrypting the first password using the preset key is not limited. For example, a symmetric encryption algorithm such as the DES algorithm can be used, or an asymmetric encryption algorithm for public key encryption can be used, or a one-way encryption algorithm can also be used.

[0157] It can be understood that steps S401 and S402 are steps for forming the first password data. The first password data can be stored as a configuration file for convenient subsequent use. Optionally, the first password data is stored as a configuration file in the same directory as the pattern design software.

[0158] S403. Generate the pattern information.

[0159] Use the pattern design software to design and generate pattern information. Exemplarily, use emCAD to design stitch patterns, color changes, etc. to generate pattern information.

[0160] S404. Decrypt the first password data using the preset key to obtain the first password.

[0161] It should be noted that the execution process of step S404 can refer to the execution process of S202 and will not be elaborated here.

[0162] S405. Encrypt the pattern information using the first password to obtain the pattern data.

[0163] The specific method for encrypting the pattern information using the first password is not limited. For example, a symmetric encryption algorithm such as the DES algorithm can be used, or an asymmetric encryption algorithm for public key encryption can be used, or a one-way encryption algorithm can also be used.

[0164] S406. Use the pattern data and the first password data to generate a pattern file.

[0165] Exemplarily, store the pattern data and the first password data in the same directory to generate a pattern file; or, form a compressed package of the pattern data and the first password data to generate a pattern file.

[0166] S407. Output the pattern file.

[0167] Optionally, the pattern file is stored in a preset file of the user terminal. Alternatively, the pattern file is output to another user terminal. For example, the user terminal is communicatively connected to an embroidery machine, and the pattern file generated at the user terminal is output to the embroidery machine so that the embroidery machine can embroider according to the pattern information.

[0168] In the method for processing a pattern file provided in an embodiment of the present application, a preset key is used to encrypt a first password to form first password data, and the first password is used to encrypt pattern information to obtain pattern data. The pattern data and the first password data are used to generate a pattern file, so that the pattern file is double encrypted, improving the security of the pattern file; thus, after the pattern file is output, double decryption is required to obtain the pattern information, effectively avoiding the theft and random tampering of the pattern file.
