摘要： Residue calculating sections respectively obtain residues which take a plurality of integers as modulus, with respect to a user ID. The plurality of integers are stored in modulus storage sections and are prime to each other. Based on these residues and parameters stored in a coding parameter storage section, component codes constructed by continuous sequences of 1 and 0 using a predetermined number of bits as a unit are respectively generated by component code generating sections. These component codes are concatenated by a concatenating section, thereby to obtain a code to be embedded, which constructs watermark information.

摘要： According to the embodiments of the present invention, identification information that is embedded by the fingerprinting scheme cannot be read out by the third party, which can protect privacy of a user. Specifically, when converting an identification number u of a user to remainder codes , and embedding thus obtained remainder codes into content information by digital watermark embedding processing, the identification number u or remainder codes are encrypted based on a secret key s. Accordingly, even though the third party who does not know the secret key s improperly detects a digital watermark to obtain an encrypted identification number v, the valid identification number u before encryption cannot be obtained. Thus, privacy of the user can be protected.
