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.

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 multimedia device having an encryption module, which prevents an encryption key from being exposed to the outside, is provided. The multimedia device includes: a key processing unit, which generates and manages an encryption key; and a data processing unit, which encrypts/decrypts content with the encryption key. Both the key processing unit and the data processing unit are located in the encryption module. The encryption module can generate an encryption key and encrypt content with the encryption key, independently of an external device, such as a CPU. In addition, the encryption module encrypts the encryption key before transmitting the encryption key to the CPU to record the encryption key on a storage medium. Therefore, it is possible to protect the content and the encryption key from hacking threats by preventing the encryption key from being exposed to the outside of the encryption module.

摘要： Method of wavelets-based multiresolution representation of a 3D image object. A center of an original 3D mesh image is set as an original of a new coordinate system, and respective coordinates of the original 3D mesh image is converted to the new coordinate system. After the coordinate conversion, the 3D mesh image is divided into a plurality of local meshes, of which boundary and inner coordinates are mapped. Next, a division level for the basis meshes is determined, and the basis meshes are divided accordingly. A parameter for local meshes divided from the basis meshes is determined. By a composition of boundaries of the reconstructed local meshes, the original 3D image object can be converted into an object to which wavelets can be applied, and as a result, the converted object can be represented at various resolutions with coefficients.
