摘要： 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.

摘要： A block where basic units of a background pattern are arranged two-dimensionally is formed so as to stably read buried information from a printed background pattern. Binary or multivalued number is assigned to the block to express information. When a binary number (bit) is assigned to a block made up of background patterns in double size, error correction can be made if an error occurs only in one background pattern while reading the block. In each background pattern, a diagonal lacking its center part is drawn, and isolated dots are placed along the other diagonal. With this, while ensuring the stability of reading the buried information after the read by a scanner, the uniformness of appearance of the printed object can be ensured.
