Abstract: An image erasing apparatus according to an embodiment includes a scanner that reads an image printed on a sheet with decolorable colorant, the image including a first owner information. A decoloring unit decolors the image printed on the sheet. An input device receives a second owner information. A controller identifies the first owner information included in the image read by the scanner, and determines whether the first owner information corresponds to the second owner information. Based on the determination, the controller selectively controls the decoloring unit to decolor the image.

Abstract: An image erasing method includes reading a sheet having an image printed thereon with decolorable colorant and an owner information image printed thereon with decolorable colorant. The method further includes identifying a first owner information based on the owner information image, and receiving a second owner information. The method further includes determining a correlation between a user corresponding to the first owner information and a user corresponding to the second owner information. The method further includes selectively controlling a decoloring unit to decolor the image and the owner information image based on the correlation.

Abstract: An image erasing apparatus comprises a reading unit configured to read a sheet having an image printed thereon with decolorable colorant and an owner information image printed thereon with decolorable colorant, and to identify a first owner information based on the owner information image. The apparatus further comprises a decoloring unit configured to decolor the sheet read by the reading unit and an authenticating unit configured to receive a second owner information. The apparatus further comprises a determining unit configured to determine a correlation between a user corresponding to the first owner information and a user corresponding to the second owner information, and an erasing controller configured to selectively control the decoloring unit to decolor the image and the owner information image based on the correlation.
