Method, program, and apparatus for preventing a reproduction of an anti-copy document, and a medium storing the program
First Claim
1. An image processing apparatus, comprising:
- a scanning mechanism configured to read images;
a first memory storing a reference dot pattern indicating an anti-copy background dot pattern;
a second memory storing image data;
an image accumulating mechanism configured to accumulate image data of an original image which is read by the scanning mechanism into the second memory;
a detecting mechanism configured to detect a background dot pattern embedded in a background image included in said image data of said original image accumulated in said second memory;
a determining mechanism configured to compare said detected background dot pattern with said reference dot pattern stored in said first memory and to determine whether said detected background dot pattern is substantially identical to said reference dot pattern; and
a code assigning mechanism configured to assign an identification code to said image data having said detected background dot pattern and accumulated in said second memory when said detected background dot pattern is determined by said determining mechanism as substantially identical to said reference dot pattern.

Abstract
An image processing apparatus includes a scanning mechanism, first and second memories, an image accumulating mechanism, a detecting mechanism, a determining mechanism, and a code assigning mechanism. The first memory stores a reference dot pattern indicating an anti-copy background dot pattern. The second memory stores image data. The image accumulating mechanism accumulates image data of an original image into the second memory. The detecting mechanism detects a background dot pattern embedded in a background image included in the image data of the accumulated original image. The determining mechanism compares the detected background dot pattern with the reference dot pattern and determines whether the detected background dot pattern is substantially identical to the reference dot pattern. The code assigning mechanism assigns an identification code to the image data having the detected background dot pattern when the detected background dot pattern is determined as substantially identical to the reference dot pattern.
