Image processing apparatus, image processing method, recording medium storing image processing program, and computer data signal embedded in carrier wave

摘要

An image processing apparatus including; a determinant image management unit managing identification information in association with protecting information specifying processing allowance and a determinant image determining a spoofing; a reader reading an image containing the identification information in response to an action to process; an extraction unit extracting the identification information from the image; an acquisition unit acquiring the protecting information and the determinant image; a first determination unit determining allowance of the processing based on the protecting information; a second determination unit determining spoofing based on differential information between the determinant image and the read image; a third determination unit determining processing allowance of the read image based on results of determination by the first and second determination unit; and an image processor performing image processing according to the action to process the read image if the third determination unit determines that the processing is allowable.
