摘要： A watermarking apparatus for embedding a watermark in a digital image, an apparatus for extracting watermark information from a watermarked image using a public key having a plurality of secret keys, and an apparatus for identifying whether a watermarked image generated by embedding a watermark in each region using a unit secret key is a copy of contents. The watermarking apparatus includes: a watermark generating unit that divides the digital image into a plurality of regions, assigns predetermined secret keys to each of the divided regions, respectively, and generates a watermark for each of the divided regions using the corresponding secret key; and a watermark embedding unit that generates a watermarked image for the digital image by embedding the watermarks in the corresponding regions, respectively, and combines the watermark-embedded divided regions. Since different kinds of keys are used when watermarking and extracting watermarked information, the watermark can be protected from illegal attacks.

摘要： A method of and an apparatus for copying and decrypting encrypted digital data. The method of copying encrypted digital data includes encrypting a first media key block to be used for decryption of the encrypted digital data using a predetermined key of a second information storage medium and storing the encrypted digital data and the encrypted first media key block in the second information storage medium. Security of data encryption is heightened by not discarding an encryption key used for an initial encryption, encrypting the encryption key used for initial encryption using another encryption key used for a second encryption, and storing the encrypted encryption key with the data. Also, since unnecessary decryption and encryption of data are not repeated, the time required for copying data is reduced, and since data is transferred between apparatuses in an encrypted state, a security level is higher.

摘要： A method and apparatus for restricting the use of a disc are provided. In this method, first, lead-in data is read out from a loaded disc. Then, a user key is read out from a lead-in area of the disc. Thereafter, the user key undergoes authentication based on a user key received from a host. The authentication is performed by comparing a random number produced by a disc drive with a decrypted random number obtained by the disc drive decrypting a random number encrypted by the host. Accordingly, the use of the disc by an unauthorized third person is restricted, thus preventing a leakage of personal information and a protection of the copyrights of data.
