Image processor, method thereof, computer program, and computer readable storage medium
First Claim
1. An image processor comprising:
- a scanning unit for reading a recording medium, the recording medium having first patterned image data printed thereon and image data printed thereon, the image data including embedded information, the first patterned image data including a latent image unperceivable by human eyes, the latent image being formed more clearly on a copy-destination recording medium when information recorded on the recording medium is copied by a copying machine;
a separating unit for separating the read image data input by the scanning unit to obtain the image data including the embedded information; and
an outputting unit for controlling output of combined image data produced by combining second patterned image data with the image data including the embedded information, the second patterned image data including a latent image unperceivable by human eyes, the latent image being formed more clearly on the copy-destination recording medium when information recorded on the recording medium is copied by the copying machine.

Abstract
A method for image processing comprising inputting and reading a combined image that includes a latent image unperceivable by the human eye, a patterned image in the background allowing the latent image to appear clearly on a recording medium when data recorded on a recording medium is copied onto another recording medium, and text and/or image data embedded with a digital watermark. The text and/or image data is extracted from the combined image and the digital watermark extracted from the text and/or image data. A permission code enabling copying of image data composed of a combination of a patterned image and the extracted text and/or image data onto a recording medium is input. The copying is regulated based on the extracted digital watermark and the permission code.

5. An image processing method comprising:
-
a scanning step of reading a recording medium, the recording medium having first patterned image data printed thereon and image data with embedded information embedded therein, the first patterned image data including a latent image unperceivable by human eyes, the latent image being formed more clearly on a copy-destination recording medium when information recorded on the recording medium is copied by a copying machine; a separating step of separating the read image data read in the scanning step to obtain the image data with the embedded information embedded therein; and an outputting step of controlling output of combined image data produced by combining second patterned image data with the image data with the embedded information embedded therein, the second patterned image data including a latent image unperceivable by human eyes, the latent image being formed more clearly on the copy-destination recording medium when information recorded on the recording medium is copied by a copying machine. - View Dependent Claims (6, 7, 8)
