Method, system, and image forming apparatus

A method performed by a data processing apparatus and an image forming apparatus, the method comprising:

• transmitting, by the data processing apparatus, an execution instruction for a job to the image forming apparatus;
• generating, by the image forming apparatus, an authentication code corresponding to the transmitted execution instruction and displaying the authentication code or information representing an encrypted authentication code on a display unit of the image forming apparatus;
• transmitting, by the data processing apparatus, an authentication code to the image forming apparatus;
• and
• executing, by the image forming apparatus, a job corresponding to the transmitted execution instruction in a case where a predetermined condition is determined to be satisfied based on the transmitted authentication code and the generated authentication code,
• wherein, in a case where a document is placed on a scanner upon reception of the transmitted execution instruction by the image forming apparatus, the image forming apparatus displays the authentication code or the information representing the encrypted authentication code.

A system comprising:

• a data processing apparatus;
• and
• an image forming apparatus,
• the data processing apparatus comprising:
• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor performs:
• transmitting an execution instruction for a job to the image forming apparatus;
• and
• transmitting an authentication code to the image forming apparatus,
• the image forming apparatus comprising:
• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor performs:
• generating an authentication code corresponding to the transmitted execution instruction and displaying the authentication code or information representing an encrypted authentication code on a display unit of the image forming apparatus;
• and
• executing a job corresponding to the transmitted execution instruction in a case where a predetermined condition is determined to be satisfied based on the transmitted authentication code and the generated authentication code,
• wherein, in a case where the transmitted execution instruction is an instruction for executing a first type job for transmitting an image generated by scanning, the image forming apparatus displays the authentication code or the information representing the encrypted authentication code, and
• wherein, in a case where the execution instruction is an instruction for executing a second type job different from the first type job, the image forming apparatus displays neither the authentication code nor the information representing the encrypted authentication code.
