Embroidery data generation system, storage medium storing terminal program, and storage medium storing apparatus program

A non-transitory computer-readable storage medium storing a set of program instructions for a terminal apparatus including an input device, a terminal communication interface, and a display, the set of program instructions, when executed by a controller of the terminal apparatus, causing the terminal apparatus to perform:

• acquiring a generation condition of embroidery data for sewing an embroidery pattern with an embroidery machine, the generation condition being inputted via the input device;
• transmitting the acquired generation condition to an embroidery data generation apparatus via the terminal communication interface;
• controlling the display to display a preview image indicating an embroidery finish of the embroidery pattern based on image data transmitted from the embroidery data generation apparatus;
• receiving a public key, the public key being generated by the embroidery machine by using a private key;
• transmitting a transmission request for the embroidery data to the embroidery data generation apparatus, the transmission request including information specifying the terminal apparatus as an apparatus of a transmission destination of the embroidery data;
• transmitting the public key to the embroidery data generation apparatus;
• receiving, from the embroidery data generation apparatus, the embroidery data encrypted by using the public key;
• and
• transmitting, to the embroidery machine, the embroidery data encrypted by using the public key.

• receiving a generation condition of embroidery data for sewing an embroidery pattern with an embroidery machine, the generation condition being received from a terminal apparatus via the apparatus communication interface;
• based on the received generation condition, generating image data for displaying a preview image indicating an embroidery finish of the embroidery pattern on a display of the terminal apparatus;
• transmitting the generated image data to the terminal apparatus having transmitted the generation condition;
• generating the embroidery data for sewing the embroidery pattern based on the received generation condition;
• receiving a public key, the public key being generated by the embroidery machine by using a private key;
• and
• encrypting the generated embroidery data by using the received public key.

• receiving a generation condition of embroidery data for sewing an embroidery pattern with an embroidery machine, the generation condition being received from a terminal apparatus via the apparatus communication interface;
• executing usage authentication of the terminal apparatus by using an authentication token transmitted from the terminal apparatus;
• in response to determining that the usage authentication is successful, generating, based on the received generation condition, image data for displaying a preview image indicating an embroidery finish of the embroidery pattern on a display of the terminal apparatus;
• transmitting the generated image data to the terminal apparatus having transmitted the generation condition;
• generating the embroidery data for sewing the embroidery pattern based on the received generation condition;
• in response to determining that the usage authentication is successful, storing, in a memory of the embroidery data generation apparatus, the received generation condition in association with the authentication token;
• storing time information in the memory, the time information indicating time when the generation condition is stored in association with the authentication token;
• in response to determining that the usage authentication is successful and that a transmission request is received from the terminal apparatus, transmitting the generated embroidery data to an apparatus specified by the terminal apparatus having transmitted the generation condition;
• determining whether a particular time has elapsed from the time indicated by the time information stored in the memory;
• and
• in response to determining that the particular time has elapsed from the time indicated by the time information, deleting the generation condition, the authentication token, and the embroidery data from the memory.
