Process executing system, information processing system, information processing method, and recording medium

An information processing method performed by a process executing system that receives image data of an output material from an apparatus and processes the output material, the method comprising:

• a step of transmitting, by a communicator, in response to a request from the apparatus, to the apparatus, output data of the output material including identification information of the output material;
• a step of receiving, by the communicator, image data generated by reading the output material by the apparatus, the output material being the output data printed by the apparatus;
• and
• step of detecting, by a duplication detector, a generation of the image data from a same output material as the output material, based on the identification information of the output material attached in the image data received by the communicator.

A non-transitory recording medium storing a program to cause an information processing system to function as:

• a communicator configured to transmit, in response to a request from an apparatus, to the apparatus, output data of the output material including identification information of the output material,
• the communicator configured to receive image data generated by reading the output material by the apparatus, the output material being the output data printed by the apparatus;
• and
• a duplication detector configured to detect a generation of the image data from a same output material as the output material, based on the identification information of the output material attached in the image data received by the communicator.
