The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A transfer and copy prevention digital recording media protection method, comprising of the following procedures:
step 1: digital recording media is placed into a computer to commence the reading of data;
step 2: a check program is started to verify the data archived on said digital recording media and whether it is a standard original disk produced by a manufacturer;
step 3: if said digital recording media contains the embedded errors of the invention herein, this indicates that said digital recording media is a standard original disk produced by the manufacturer; a check program in the memory of a computer then decrypts the output or guides the reading or correct execution of the data and reads the contents of said digital recording media; and
step 4: if said digital recording media does not contain said embedded errors, the protection scheme set-up by the manufacturer is executed to safeguard the content of said digital recording media from unlawful transferring and copying.
2. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said digital recording media consists of CD, VCD, DVD, MO, high-density magnetic tape, flash disks, and other standardized specification digital storage media.
3. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said check program instructs optical disk drives how to skip or decrypt said embedded errors and thereby read data correctly.
4. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said embedded errors can be archived in a concentrated arrangement.
5. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said embedded errors can be archived in a dispersed arrangement.
6. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said embedded errors can be of a specification wherein they are recorded by adding one or more, contiguous or scattered error bits.
7. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said embedded errors are recorded into position fully encrypted or partially encrypted.
8. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said check program correlation is executed when said digital recording media begins operation or executed after said digital recording media is operating.
9. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said decryption record is temporary and deleted when the system is switched off.
10. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said decryption file generates an encrypted or a non-encrypted unlocking code that is permanently stored in other recording media such that the user is not required to repeat verification.
11. The transfer and copy prevention digital recording media protection method according to claim 10, wherein said unlocking code correlates the hardware and software of a computer (such as computer mainboard BIOS, CPU serial numbers, optical disk drive drive numbers, peripheral interface cards, displays, network cards, and operating system versions and serial numbers, etc.) and additionally detects according to a generated check code.
12. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said protection scheme check method is based on protection requirements and initiates the correlation of check numbers (such as software registration numbers, software serial numbers, and optical disk serial numbers, etc.) or correlates said check numbers through an external device (such as a magnetic disk, another optical disk, magnetic card, or the Internet, etc.).
13. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said manufacturer uses software designing to create protective method combinations of embedded errors such as invalid tracks, hysteresis loops, corrupted tracks, altered data formats, or virus data, and other similar items.
14. The transfer and copy prevention digital recording media protection method according to claim 1, wherein said protection scheme can be segmentally or wholly configured in transfer- and copy-protected digital recording media and, furthermore, with encryption function support.
15. The transfer and copy prevention digital recording media protection method according to claim 1, wherein the protection scheme set up by the manufacturer is capable of launching a virus, sending an e-mail to the manufacturer, terminating execution, and other protective countermeasures.
16. A transfer and copy prevention digital recording media protection master disk method, comprising of the following procedures:
a data protection table is supplied to provide for a transfer- and copy-protected master disk.
the original data is read-in to produce transfer- and copy-protected recording media.
an encryption record is produced for the original data based on manufacturer requirements.
whereby said encryption record, correct data, and embedded errors are recorded to said transfer- and copy-protected digital recording media master disk.
17. The transfer and copy prevention digital recording media protection master disk method according to claim 16, wherein said digital recording media consists of CD, VCD, DVD, flash disks, high-density magnetic tape, MO, and other standardized specification digital storage media.
18. The transfer and copy prevention digital recording media protection master disk method according to claim 16, wherein said method can be utilized in combination with said data protection table to generate single or multiple embedded errors.
19. The transfer and copy prevention digital recording media protection master disk method according to claim 16, wherein said transfer- and copy-protected digital recording media master disk method is capable of including a check program or a manufacturer-designated means that retrieves the check and decryption program.
