Description
Technical field
The present invention relates to the cdrom encryption technical field, specifically a kind of CD and DVD CD encryption method that prevents the CD bootlegging.
Background technology
People have impelled developing rapidly of CD industry to the continuous increase of the quantity of information requirement.But meanwhile, the development of digital technology has also caused serious problem of piracy.The cost of manufacture of CD is low, and distribution is convenient, and these two characteristics are provided convenience for pirate making.Different with traditional analogue technique product piracy, digital pirated CDs almost is being as good as with master qualitatively, and a production equipment can be made a large amount of illegal disks in very short time.All rely on the industry of copyright protections-comprise moviemaking, music industry and computer software industry-take a bath Yin CD is pirate.Counterfeit has hindered the development of above-mentioned economic department, thereby has dampened investor and innovator's enthusiasm, has constituted obstacle to creating valuable new working opportunity.
For preventing piracy, people have done all effort, have studied multiple anti-piracy way, and reached anti-effect of duplicating to a certain extent, but copyright owner and disc manufacturer have also been paid expensive expense simultaneously: the copyright owner must pay antitheft copy fee by quantity; Disc manufacturer must obtain mandate every year and put pirate expense by the quantity payment.For general author, such as advertising information, education CD, short run video display CD or the like, its cost is difficult to bear.
Summary of the invention
The objective of the invention is to set up a kind of a kind of CD encryption method of uniqueness, and reach following effect: prevent optical disc copy, promptly prevent the imprinting software used always, for example, and Nero, Roxio etc. directly duplicate CD; Prevent from CD content is copied on the hard disk imprinting once more from the hard disk.
Technical scheme provided by the invention is divided into two steps:
Step 1, the pre-service of source of parents data:
The first, utilization imprinting software is set up the data of optical disk form by the carrier format of the source of parents data that the client provides;
The second, in described data of optical disk form, read in encryption menu according to the requirement of carrier format, the source of parents data that again client provided are read in the described data of optical disk form, the regeneration image file; The source of parents data that described client provides comprise data directory and data file;
The 3rd, the utilization software for editing opens described image file, and described encryption menu, data directory are hidden;
The 4th, the utilization software for editing opens described image file, the data file except that specific file is carried out logic amplify;
The 5th, utilization imprinting software will be hidden with image file imprinting after logic is amplified and become the source of parents data disks;
Step 2, mother CD burning:
The first, the source of parents data disks is read in the stamper data system;
The second, carry out the imprinting of stamper by normal stamper production process;
The 3rd, burn the encryption menu in the described stamper of damage.
Described carrier format comprises: CDROM, VCD, DVDROM or DVD_VIDEO.
When carrier format was CDROM and VCD, the size of described encryption menu was 10～50M; When carrier format was DVDROM and DVD_VIDEO, the size of described encryption menu was 60～150M.
Described imprinting software comprises Nero, Roxio; The described UltraEdit of software for editing.
Described data file comprises executable file, text, graphic file, multimedia file.As: EXE, MPEG, MP3, DCR, CCT, PPT, DOC etc.
Described specific file is that a class can not be carried out the file that logic is amplified, and these files comprise PDF, FLASH, HTML, INF file.
The present invention burns the damage stamper in certain location in stamper manufacturing process, adopt software to source of parents data logical encrypt, can prevent from data are directly copied on the hard disk, but can not stop the whole dish to CD to duplicate.And directly produce certain CD (in fact being metal negative) damage on the hardware, and produce data read errors in the time of can making optical media replication, prevent illegal purpose of duplicating thereby reach.
Because " encryption menu " be positioned at data of optical disk form reference position, so after the normal imprinting of stamper, " laser head " moved to above-mentioned position carry out the people and burn for imprinting, wherein the position of burning of CD is radius 26.5mm; The position of burning of DVD is radius 24.5mm; Burning width is 0.5mm.
Description of drawings
The present invention will obtain more deep understanding by following accompanying drawing:
Fig. 1 is the whole CD manufacturing process of producing from the source of parents data to compressing tablet.
Embodiment
1, adopt software to source of parents data logical encrypt; 2, in the stamper preparation process, burn the damage stamper in certain location.
Step 1: adopt software to source of parents data logical encrypt:
First: utilization Nero imprinting software is pressed the newly-built data of optical disk form of carrier format (CDROM, VCD, DVDROM, DVD_VIDEO) of source of parents data.
Second: read in encryption menu, include a JM.EXE file (to CDROM, VCD, this document size is 30M, and to DVDROM, DVD_VIDEO, file size is 100M), all read in the source of parents data subsequently; Generate image file ISO or NRG.
The 3rd: utilization UltraEdit program is opened image file, and encryption menu, data directory and data file are hidden and the logic amplification.Hiding herein is not meant that general property is the catalogue of " H ", and is meant and not only can't see below Windows by handling, and can't see with dir/a under DOS, but it is present on the CD yet; The virtual amplification of some file with under the root directory makes it to be copied to hard disk.
The 4th: the image file that logical encrypt is finished is burnt on CDR or the DVDR.
Step 2: in stamper manufacturing process, burn the damage encryption menu;
Adopt software to source of parents data logical encrypt, can prevent from data are directly copied on the hard disk, but can not stop whole dish to duplicate CD.And directly produce certain CD (in fact being metal negative) damage on the hardware, and produce data read errors in the time of can making optical media replication, prevent illegal purpose of duplicating thereby reach.
Because " encryption menu " is positioned at the reference position of data of optical disk form, so after the normal imprinting of stamper, " laser head " moved to above-mentioned position carry out the people and burn for imprinting, wherein the position of burning of CD is radius 26.5mm; The position of burning of DVD is radius 24.5mm; Burning width is 0.5mm.
As can be seen from Figure 1, the imprinting of the pre-service of source of parents data, metal negative finally all will be reflected on the effect of CD.That is to say that in fact cdrom encryption is exactly that the source of parents data are carried out in certain location it being burnt the overall process of damage in logical encrypt and the stamper preparation with software.
In general, " data recorded area internal diameter " is the reference position of data of optical disk form, and " encryption menu " is positioned at herein, and CD, DVD have nothing in common with each other.
Bibliographic structure of under Windows operating system, seeing and file size, for example, catalogue " data ", " copyright statement " are hidden, and also can't see with dir/a under DOS; File " start.exe " is by the virtual 2000M that is amplified to.Generally speaking, the user is unable to find out directory name, also just can't the interior file of duplicate catalog.
The width of " encryption menu " is about 0.5mm.Because client's data are positioned at outside the encryption menu The corresponding area, be not affected during therefore normal the use.
When the whole dishes of software such as using Nero duplicates this CD-enciphering, burnt regional continuous data read errors and caused duplicating failure owing to run into; When attempting from stamper independent copying encrypted file, produce parameter error and can't with data read to other storeies, avoid further bootlegging.
The present invention at first adopts software to source of parents data logical encrypt, in certain location stamper is carried out the laser burn damage then in the stamper preparation process.Obtain encrypting stamper and compressing tablet is produced corresponding CD-enciphering by these 2 processes, thereby reach the requirement that prevents optical media replication effectively.
