    Abstract: An image output system includes a computer and a complex machine connected to the computer. A password generating section of the complex machine, in a case where a user ID transmitted from a transmitting section of the computer is stored in a HDD, generates a password which is different from the user ID, and the transmitting section transmits the password generated by the password generating section. A controller, in a case where the password received by a password receiving section and the password transmitted from the password transmitting section to the computer, controls an image forming section to output image data which is not combined with electronic watermark information by an electronic watermark information combining section.

    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.

    Abstract: Disclosed herein is a method for identifying a constellation of alignment marks within an arrangement of computer readable marks in an image (1412), the arrangement of computer readable marks (1412) including alignment marks (1401-1406) and data carrying marks (1407-1410). The alignment marks (1401-1406) define a reference grid within the arrangement of computer readable marks and the data carrying marks (1407-1410) are modulated with respect to the reference grid to encode data. The method selects at least two marks (1501, 1502) from the arrangement of computer readable marks and determines a rotation centre with reference to the selected marks (1501, 1502). The method then determines rotated positions for the selected marks by rotating each of the selected marks by a predetermined angle about the rotation centre. For each rotated position, a mark having a position that is less than a predetermined threshold from the rotated position is located from the arrangement of marks and then the selected marks and the located marks are identified as the constellation of alignment marks.

    Abstract: The method extracts a plurality of blocks from a master image, processes image data corresponding to each block by orthogonal transform, compares coefficients of adjoining blocks with each other, and modifies the order of magnitude of the coefficients, based on bit information to be embedded. The bit information to be embedded is constructed as a basic pattern, which is generated, for example, by the density pattern method. The basic pattern is embedded in image data iteratively. The process of iteratively embedding the basic pattern enhances the resistance against various attacks.
