Abstract
A device to protect a reproduction of a disk, a method of protecting the reproduction of the disk, and a recording medium for the method. The device includes a key setting unit to generate a key to encode lead-in region information of the disk desired to be reproduced and a key storing unit to store the key. A key storing unit in the device stores the key generated by the key setting unit, and a reproduction determining unit determines whether to reproduce the disk using the key.
Claims19
A device to protect a reproduction of a disk, comprising:
- a key setting unit generating a key to encode lead-in region information of the disk and registering the key;
- a key storing unit storing the key generated by the key setting unit;
- and
- a reproduction determining unit determining whether to reproduce the disk using the key stored in the key storing unit.
A method of protecting reproduction of a disk, comprising:
- registering a key and a key value of the disk by encoding lead-in region information of the disk;
- and
- determining reproduction of the disk requested to be reproduced using the registered key.
A method of setting up a key on a disk, comprising:
- receiving a request from a user to set up a lock on the disk;
- reading data in a lead-in region of the disk;
- generating a key for the disk using the data read from the lead-in region of the disk;
- storing the key;
- and
- receiving and storing a password for the stored key.
A method of reproducing a disk, comprising:
- generating a key using data in a lead-in region of the disk to be reproduced;
- storing the key and a corresponding key value;
- searching for a reference key value;
- and
- reproducing the disk when the reference key value is equal to the key value generated for the disk.
A computer-readable recording medium on which programs are recorded to provide a method of protecting reproduction of a disk, the method comprising:
- setting up a key for the disk desired to be recorded;
- encoding lead-in region information of the disk;
- and
- determining whether to reproduce the disk using the key.
A computer-readable recording medium on which programs are recorded to provide a method of protecting reproduction of a disk, the method comprising:
- receiving a request from a user to set up a lock on the disk;
- reading data in a lead-in region of the disk;
- generating a key for the disk using the data read from the lead-in region of the disk;
- storing the key;
- and
- receiving and storing a password for the stored key.
A computer-readable recording medium on which programs are recorded to provide a method of protecting reproduction of a disk, the method comprising:
- generating a key using data in a lead-in region of the disk to be reproduced;
- storing the key and a corresponding key value;
- searching for a reference key value;
- and
- reproducing the disk when the reference key value is equal to the key value generated for the disk.
A device to protect a reproduction of a disk, comprising:
- a key setting unit generating a key to encode lead-in region information of the disk and registering the key;
- a key storing unit storing the key generated by the key setting unit;
- and
- a reproduction determining unit registering a password input from a user for the key.
A device to protect a reproduction of a disk, the device having a key setting unit to generate a key to encode lead-in region information of the disk and to register the key, a key storing unit to store the key generated by the key setting unit, and a reproduction determining unit storing a password input from a user for the key, the device comprising:
- a password comparing unit receiving another password from the user, allowing reproduction of the disk when the password of the key of the disk to be reproduced is the same as the other password from the user, and preventing the reproduction of the disk when the password for the key of the disk to be reproduced is not the same as the other password from the user.
