Abstract
An image processing apparatus includes an image acquiring unit that acquires image data, an additional-data generating unit that generates additional data, a first-code-image generating unit that generates first-code image data, a first-superimposed-image producing unit that combines the first-code image data with the image data, thereby producing first-superimposed image data, a detecting-data generating unit that generates data for use in detecting modification made to the first-superimposed image data, a second-code-image generating unit that generates second-code image data, and a second-superimposed-image producing unit that produces second-superimposed image data by clipping a portion of the second-code image data, the portion corresponding to an image area of the first-superimposed image data where the first-code image data is provided, and combining the first-superimposed image data with the second-code image data from which the portion has been clipped.
