Abstract:
This patent specification describes an image forming apparatus which can effectively check and prevent the unauthorized image processing so that the obtained image data may not be different from the content which a user demands. In one example, an image forming apparatus includes a defining mechanism, a reader, a detector, a comparator, and a notifier. Then, a certain tint block pattern is detected and information of the result is notified effectively.
