    Abstract: The method for water-marking digital books with parameters includes developing, for each parameter, a new typeface on the basis of a pre-existing typeface, by creating at least one new code/glyph pair. The method includes developing a new coded text on the basis of the pre-existing coded text by replacing, in the pre-existing coded text, at least one code or group of codes from the pre-existing typeface. The method further includes allowing display of a character or a combination of characters from the digital book by the code or the group of codes from the new typeface allowing display of the graphically identical character or combination of characters on any screen. The code/group of codes from the new typeface has/have at least the code from the new code/glyph pair. The method also includes providing the new coded text and the new typeface as a water-marked digital book.

    Abstract: A computer-based method and a system for adding and printing variable security data. The system includes a memory, a processor, and a printer. The memory stores received print data. The processor modifies the print data for adding variable security print data and sends the modified print data for printing. The printer receives and prints the modified print data. The variable security data may vary between different printing operations. The processor captures a portion of the stored print data based on data-capturing criteria and modifies the stored print data based on the captured portion of the stored print data. The data-capturing criteria may be user-defined and may include leading tag data, trailing tag data, matching tag data, or combinations thereof for indicating a relative position of the captured data.

    Abstract: Line spacing values in a document image are extracted and a variance is calculated for fluctuations in the line spacing values. When the calculated variance is higher than a preset threshold value, the document image is determined as having watermark information embedded therein. Such use of the variance in the line spacing values enables high-speed determination of the presence or absence of line-spacing watermark information. At this time, it is possible to speed up the determination by using only some line spacing values in the document, instead of using all line spacing values.

    Abstract: Provided is a digital watermarking technology for embedding digital watermark information in text data thereby to generate a digitally watermarked image. The technology includes a digital watermarking program, a digital watermarking device and a digital watermarking method, in which digital watermark information can be embedded in document in such a way as not to be easily detected visually and be stably detected even after being printed out, copied or scanned by detecting the features of a character as data to be digitally watermarked, such as the direction and thickness of a line composing the character as the features thereof and embedding the digital watermark information in the character on the basis of the detected features.

    Abstract: A text watermarking method embeds an auxiliary message in an original electronic text document to form a watermarked text document. The method applies a spreading function to message symbols to spread the symbols over a carrier, which forms a modulated carrier. It maps elements of the modulated carrier to corresponding inter-word spaces in the electronic text document, and applies an embedding function to modify the corresponding inter-word spaces according to elements of the modulated carrier signal such that the modified inter-word spaces hide the modulated carrier signal in the watermarked text document. The message symbols are automatically decodable from the watermarked document without the original electronic text document. A compatible decoder extracts the auxiliary message from a printed or electronic watermarked text document. The decoder automatically measures inter-word spaces in the watermarked text document. It estimates elements of a modulated carrier signal embedded in the inter-word spaces to form an estimated modulated carrier signal, and applies a de-spreading function to the estimated modulated carrier signal to extract message symbols.
