example 1

[0036] Example 1. Burn data

[0037] If the command to record data from the optical drive to the optical disc is obtained, the optical disc security management device sends a recording instruction to the optical drive; the optical drive sends the data to be recorded on the terminal device to the optical disc security management device. memory; the optical disc security management device encrypts the data to be recorded in the memory using a preset encryption algorithm, and instructs the optical drive to record the encrypted data to be recorded to the optical disc;

[0038] like image 3 As shown, it is a schematic diagram of the overall flow of the recording process in the second embodiment of the disc security management method of the present invention. After the registration process is completed, the process of using the disc for recording may include:

[0039] Step 301, before the user puts the optical disc into the optical drive, the optical disc security management devic...

[0047] Example 2, read data

[0048] If the command for the optical drive to read data from the optical disc is obtained, the optical disc security management device sends a read instruction to the optical drive; the optical drive sends the data to be read in the optical disc to the optical disc memory of the security management device; the optical disc security management device uses a preset decryption algorithm to decrypt the data to be read in the memory, and instructs the optical drive to read the decrypted data to be read to the terminal equipment.

[0049] like Figure 4 As shown, it is a schematic diagram of the overall flow of the reading process in the second embodiment of the optical disc security management method of the present invention. After the registration process is completed, the process of reading the data in the optical disc may include:

[0050] Step 401 , before the user puts the optical disc into the optical drive, the optical disc security managemen...

Abstract

The invention discloses optical disk safety management method and device. In the optical disk safety management method, the optical disk safety management device reads a chip identification number of a safety chip packaged on an optical disk; the optical disk safety management device acquires the chip identification number burned in the optical disk and read by a CD-ROM device; if the chip identification number burned in the optical disk is identical with the chip identification number of the safety chip, the optical disk safety management device sends a burning instruction or a reading instruction to the CD-ROM device to encrypt data to be burnt or decrypt data to be read, otherwise, the optical disk safety management device instructs the CD-ROM device to stop running. The optical disk safety management device compares the chip identification number of the safety chip with the chip identification number burned in the optical disk, thereby facilitating the safety management on the optical disk and realizing special disk for special use; an institution needed to be secreted realizes the management on each optical disk in the institution, thereby avoiding divulging a secret; and a merchant can also avoid pirating.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer storage technology, in particular to a method and device for optical disc security management. Background technique [0002] Compact Disc (Compact Disc) is an optical storage medium developed in modern times that is different from magnetic carriers. It uses a focused hydrogen ion laser beam to process the recording medium to store and reproduce information, also known as laser disc. Because the capacity of floppy disks is too small, optical discs are widely used due to their large capacity. A CD for listening to music is a kind of disc, and a VCD and DVD for watching movies are also a kind of disc. [0003] The storage technology of the existing optical disc is public, and the burning optical drive can read and copy the content of the optical disc arbitrarily, and the burning optical drive can burn the content in the optical disc arbitrarily. It is impossible to carry out securi...
