    Abstract: Improved techniques for making copy detection patterns and using them to detect copying relationships between digital representations. The techniques include techniques for including a message in a copy detection pattern without altering the copy detection patterns entropy and reading the message, techniques for using a copy detection pattern on an analog form to determine whether the analog form is an original analog form without reference to a digital representation of the original of the analog form's copy detection pattern, techniques for increasing the sensitivity of copy detection using copy detection patterns by modifying one of two copy detection patterns that are being compared to take into account alterations resulting from the copying process, techniques for distributing a copy detection pattern across a document, and techniques for using the entropy of a copy detection pattern to locate the copy detection pattern. Also disclosed are applications of copy detection patterns with copying that involves transformations between the digital and analog forms and with digital-to-digital copying.

    Abstract: The application discloses various methods and systems to provide substitute information or objects for, e.g., substitution when making copies of media objects (e.g., audio, video or images). One method includes: receiving i) an identifier obtained from a steganographic encoding encoded in a media object, and ii) state information associated with the steganographic encoding or associated with the media object; obtaining—from a storage location—a substitute media object corresponding to the identifier; adjusting the substitute media object in accordance with the state information; providing the adjusted, substituted media object. Another method includes: receiving an identifier obtained from a steganographically encoded media object; accessing memory associated with at least a portion of the identifier to obtain an address of a remote data repository, the remote data repository including at least a plurality of substitute media objects corresponding respectively to a plurality of identifiers; forwarding: i) at least a portion of the identifier obtained from the steganographic encoding, and ii) an instruction to the remote data repository at the address, wherein the instruction includes a request to provide a substitute media object corresponding to at least a portion of the identifier obtained from the steganographic encoding. Of course, other methods and combinations are provided as well.

    Abstract: A digital camera includes: an optical system for forming an optical image of a subject; an image pickup unit that converts the formed optical image of the subject and outputs a subject image; and a recording unit that associates the subject image output by the image pickup unit with a layout definition data group and stores the subject image in a nonvolatile memory. The layout definition data group is stored in the nonvolatile memory and is made up of pieces of layout definition data that define a layout to draw a subject image for a drawing medium of a specific size. The pieces of layout definition data making up the layout definition data group with which the subject image is associated defines similar layouts for drawing media of difference sizes.
