Method and apparatus are disclosed for publishing locational copyrighted watermarking video. According to some embodiments, a method for embedding location information into a video comprises: separating the video into at least one key frame and at least one in-between frame set corresponding to the at least one key frame; receiving location data for the at least one key frame; encrypting the location data for the at least one key frame based on a location private key; and embedding the encrypted location data into the at least one key frame.

This method of water-marking digital books with parameters comprises: - the formulation (56) for each parameter of a new character font on the basis of a pre-existing font, by creating at least one new code‑glyph pair, - the formulation (58) of a new text coded on the basis of a pre-existing coded text by replacing in the pre-existing coded text at least one code or group of codes of the pre-existing font making it possible to display a character or a combination of characters of the digital book by the code or the group of codes of the new font making it possible to display the graphically identical character or the combination of characters on any screen, this code or this group of codes of the new font comprising at least the code of the new code‑glyph pair, - the provision (64) in the guise of a watermarked digital book of the new coded text and of the new font.
摘要:
A method for altering an electronic representation of an item having a watermark comprises: receiving an electronic representation of an item (200), the electronic representation comprising a first watermark, the first watermark corresponding to a first watermark definition; receiving a signal (210) indicating that a second watermark definition is to be used; and altering (220) the electronic representation to comprise a second watermark corresponding to the second watermark definition.
摘要:
A recording medium recording method for recording information on a recording medium, wherein management information prepared for a plurality of types of recording medium is buried as data additional information on a content to be recorded, the data on the content where the additional information is buried is subjected to a first encoding, the management information is subjected to a second encoding, the encoded content data and the encoded management information are modulated, and they are recorded on a recording medium. A recording medium thereof is also disclosed.
摘要:
An apparatus and method for displaying a copy-deterrent pattern (104) within a digital motion picture in order to discourage recording of the motion picture using a video camera or other sampling recording device. A copy-deterrent pattern (104) could be, for example, one or more symbols, a random pattern, a digital watermark or a text message (106). The copy-deterrent pattern (104) comprises a plurality of pixels within each frame of the digital motion picture, and the displayed pixel intensities are modulated at a temporal frequency using modulation characteristics deliberately selected to be imperceptible to human observers while simultaneously producing objectionable aliasing in any copy made using a video camera.

A print management system includes a policy (113) that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers (130) are managed by a print management system (112). Each printer (130) can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system (112) routes the print job to a printer (130) that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.
摘要:
In an image processing apparatus which has an operating system (102) and scanner driver (103), is connected to a scanner (104) for reading an original and converting it into an image signal, and stores image data read by manipulating the scanner (104), a forgery determination processing module (103-2) of the scanner driver (103) compares the read digital watermark data with specific image data to determine the matching degree, and an anti-forgery control module (106) controls predetermined image processing on the basis of the determination result for the image data read by the scanner driver (103).
