A watermark embedder embeds a cryptographic key as a digital watermark into input host data and thereby generates key-embedded host data, and then provides it to a hash generator and a signature attacher. A hash generator generates a hash by putting the key-embedded host data into a one-way function, and provides the hash to an encryptor. The encryptor encrypts hash generated by the hash generator with the cryptographic key and thereby generates a digital signature. The signature attacher attaches the digital signature generated by the encryptor to the key-embedded host data generated by the watermark embedder, and outputs the signature-attached key-embedded host data.
