The present invention provides a kind of preposition encryption method of read-only optical disc, including: step a: source of parents data are carried out logic encryption.Carry out step b subsequently: imprinting stamper；Including: b-1, reads in stamper data system by source of parents data disks；B-2, amendment imprinting program makes laser instrument change corresponding to the imprinting pulse signal in encryption menu region, enable the imprinting in encryption menu region of this imprinting pulse signal to go out hole point that off-gauge length is 15T～25T；B-3, uses amended imprinting program imprinting stamper, and in encryption menu region, imprinting goes out the hole point that off-gauge length is 15T～25T；Other normal data district beyond encryption menu region carries out normal mode imprinting.This method goes out off-gauge hole point of CD-ROM drive None-identified in ad-hoc location imprinting, it is not necessary to again stamper encryption menu region is burnt after mother CD burning, thus simplifying technological process so that make CD-enciphering more convenient.
Description
Technical field
The present invention relates to a kind of CD manufacture field, especially a kind of read-only optical disc encryption method preventing CD bootlegging.
Background technology
The application of current read-only optical disc very extensive, wherein to have data capacity big for the read-only optical disc of DVD format, and the advantage that manufacturing cost is low is subject to the welcome of dealer in many industries such as publication, video display, softwares.But the piracy of CD is also more rampant at present, and copyright owner spends the achievement of a large amount of painstaking effort and cost, is often stolen easily by bootlegger, cause money and technical loss.The piracy how taking precautions against read-only optical disc has had become as current problem in the urgent need to address.In order to prevent CD pirate, people have studied some anti-piracy schemes, but the technology that the scheme being those that have previously been has is careful not, it is easy to being cracked, some realization rate are excessively complicated, is unfavorable for the convenience produced.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of preposition encryption method of read-only optical disc, it is possible to prevent DVD to be illegally duplicated, simplify the processing technology of stamper simultaneously.The technical solution used in the present invention is:
A kind of preposition encryption method of read-only optical disc, including:
Step a: source of parents data are carried out logic encryption, specifically includes:
A-1, the carrier format of the source of parents data that utilization imprinting software provides by client sets up data of optical disk form；
A-2, writes encryption menu according to the requirement of carrier format in described data of optical disk form, then source of parents data client provided write in described data of optical disk form, regeneration image file；The source of parents data that described client provides include data directory and data file；
A-3, uses software for editing to open described image file, described encryption menu, data directory is hidden；
A-4, use imprinting software by hide after image file imprinting become source of parents data disks；
Carry out step b subsequently: imprinting stamper；Including:
B-1, reads in stamper data system by source of parents data disks；
In conventional processing method, next typically require the encryption menu carrying out the normal imprinting program of stamper He burning in stamper, the encryption menu region of stamper is formed one and burns annulus.Theing improvement is that of the preposition encryption method of this read-only optical disc, comprises the following steps: after step b-1
B-2, amendment imprinting program makes laser instrument change corresponding to the imprinting pulse signal in encryption menu region, enable the imprinting in encryption menu region of this imprinting pulse signal to go out hole point that off-gauge length is 15T～25T；
B-3, uses amended imprinting program imprinting stamper, and in encryption menu region, imprinting goes out the hole point that off-gauge length is 15T～25T；Other normal data district beyond encryption menu region carries out normal mode imprinting.
Advantages of the present invention: first source of parents data are carried out logic encryption by the present invention, then when mother CD burning, in encryption menu region, imprinting goes out the hole point that off-gauge length is 15T～25T, has reached prevent conventional imprinting software from CD directly being replicated and prevent from CD content copies to the purpose that after on dish, imprinting replicates again.This method is by adjusting imprinting program, by the change of laser instrument in the process of an imprinting, go out off-gauge hole point of CD-ROM drive None-identified in ad-hoc location imprinting, it is not necessary to again stamper is burnt after mother CD burning, thus simplifying technological process so that make CD-enciphering more convenient.And damaging in stamper compared with the method for encryption menu with burning in the past, CD outward appearance will not be produced big impact by the minor variations of hole point length.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1:
Before stamper carries out imprinting, it is necessary first to according to mode as before, source of parents data are carried out pretreatment, namely source of parents data are carried out logic encryption.Carry out the following step,
A-1, the carrier format (such as DVD-ROM or DVD_VIDEO) of the source of parents data that utilization Nero imprinting software provides by client sets up data of optical disk form；
A-2, writes encryption menu according to the requirement of carrier format in described data of optical disk form, then source of parents data client provided write in described data of optical disk form, regeneration image file ISO or NRG；The source of parents data that described client provides include data directory and data file；
A-3, uses UltraEdit software for editing to open described image file, described encryption menu, data directory is hidden；
A-4, use Nero imprinting software by hide after image file imprinting become source of parents data disks；
Need to carry out the imprinting of stamper subsequently,
First carry out step b-1, source of parents data disks is read in stamper data system；
For DVD, the physical region of encryption menu is between the 24.3mm～25mm of CD radius.In the international standard of read-only optical disc, containing " platform " between a series of hole point and hole point on physical track, defining the unit length of hole point and platform typically by time T, a T is 231.4ns；On DVD, the hole point length of standard is between 3T～11T, this method will go out random length hole point in the imprinting of encryption menu region, and namely some length in hole reaches between 20T(15T～25T, and this example selects 20T), so that CD-ROM drive None-identified, thus reach to prevent the purpose of bootlegging.Outside being positioned at the region corresponding to encryption menu due to the data of client, therefore stamper is not affected when normal use.
Carry out following steps subsequently:
B-2, amendment imprinting program makes laser instrument change corresponding to the imprinting pulse signal in encryption menu region, enable the imprinting in encryption menu region of this imprinting pulse signal to go out hole point that off-gauge length is 20T；
B-3, uses amended imprinting program imprinting stamper, and in encryption menu region, imprinting goes out the hole point that off-gauge length is 20T；Other normal data district beyond encryption menu region carries out normal mode imprinting.
Mother CD burning terminates rear, utilizes the DVD that stamper suppresses can also possess the anti-piracy technique that same stamper is consistent.
Comparing with original technical scheme, eliminate the step of burning of stamper, encryption measures is preposition to be completed in the writing process of stamper, therefore simplifies production technology, and cheats a little upper trickle change and the outward appearance of CD will not be caused big impact.
