1. An image decoloring apparatus comprising:
a decoloring unit configured to decolor an image formed with decolorable coloring material on a sheet;
a scanner configured to generate image data by scanning the sheet before the image is decolored by the decoloring unit;
a storage unit configured to store the image data; and
a processor configured to:
detect a recognition code on the sheet based on the image data generated by the scanner,
decode the recognition code and output attribute data of the sheet which is included in the recognition code,
acquire security information related to security of the sheet and corresponding to the output attribute data,
determine whether to decolor the image on the sheet and whether to store the image data as a backup copy of the image formed on the sheet before the decoloring unit decolors the image, based on the acquired security information, and
based on the determination made by the processor, control the decoloring unit and the storage unit to prevent the storage unit from storing the image data when the determination is made to not store the image data as the backup copy.
