Patent ID: 7533421

Claim:
A method for encoding a confidential optical disc with a burner, the method comprising the steps of: receiving a signal for creating the confidential optical disc to switch a burner into a burning mode; setting a data-accessing password for future verification, wherein the data-accessing password is placed to a secret file set descriptor and allocated on any unoccupied space of an optical disc, wherein the secret file set descriptor is a non-standard file and stores a preset address pointing to a root directory record of a real directory tree; selecting one of data sources for public viewing and confidential viewing data to be burned on the disc; receiving a start burn signal to begin a data encoding process; creating a temporary file system as a buffer that includes two stages: creating a standard file set comprising a standard file system including a dummy directory tree pointing to dummy data, wherein the standard file system defines the next available address as the start of the secret file set descriptor, and creating a parallel file set comprising the secret file set descriptor and the real directory tree pointing to real data; and burning the buffer to the optical disc to produce the confidential optical disc.
