Image Forming System, Image Forming Apparatus, and Method in which an Application is Added

摘要

An image forming system includes a first computer, a second computer, and an image forming apparatus. The first computer is configured to provide an application file to a first special hash function and generate a first special hash value corresponding to an input first parameter value. The second computer is configured to generate an installation package file including the application file and the first special hash value. The image forming apparatus is configured to provide the application file to a second special hash function that is the same as the first special hash function, generate a second special hash value corresponding to a second parameter value that is stored in the image forming apparatus and that is the same as the first parameter value, and perform a specified process to the application file if the first special hash value matches the second special hash value.
