Abstract
The present invention designs a kind of method of floppy disk encryption, can prevent that high-level copy software from being by revising the relevant instruction in the computer operating system to its principle of duplicating of user program, floppy disk tracks is formatd number to be extended to more than 40, then the part magnetic track is carried out non-standard formatted processing, and in particular sector, insert key parameter, make the copy software that under normal running system start-up, moves can't finish replication task.Whether with an encipheror floppy disk is differentiated is the read-write operation of former dish again.
The present invention can protect execute file, also can embed in the high-level language programs and data base management system (DBMS) of explanation type, forms the encryption software system.
Description
The invention belongs to the Computer Applied Technology field.
Flexible plastic disc is the main storage medium of the various softwares developed of computer user.The floppy disk that not encrypted is handled is easy to duplicate.People are in illegal copies that prevent software and use without compensation, and the countermeasure of taking mainly contains two:
One, encryption software is made chip, skewer is in the expansion slot of computer motherboard, and user program is used in combination with the skewer card, and software is normally moved.Do not have this skewer card, the software that duplicates can not use.CN86104856 comes to this as Chinese patent.This method reliability height, but cost of manufacture is higher, and take expanded slot of computer, and influence other function expansion of machine, use limited.
Be that the floppy disk manufacturing machine is damaged two.Protected software verifies to the floppy disk that uses at first that in when operation differentiating floppy disk has not damaged and damage location, and with software in the data of storing compare, thereby determine whether the floppy disk that is used encrypts former dish.
Adopt special process method to remove the floppy disk magnetic as BrP GB2137533; U.S. Vault company adopts laser instrument at the floppy disk hole burning.These two kinds of method complex process, the cost of manufacture height is difficult for promoting.Chinese patent CN87101040 adopts needle-shaped tool to scratch floppy disk, and magnetic head and disc are all had adverse effect.
Purpose of the present invention, be with easy, practical method, floppy disk is carried out non-standard formatted processing, change the form of information storage on the disc, track number and sector byte are made special marking, high-level copy software can't be discerned, and be aided with encryption software user program is handled, make encrypted program must have the support of encryption disc could normal operation, thereby prevented the bootlegging and the use without compensation of user program.
Principle of the present invention is, the instruction of relevant diskette formatting in the computer operating system (DOS) is write in modification, utilize computer disk drive unit and interrupt instruction system, the format track number of floppy disk is extended to 48 roads, then the standard magnetic track is carried out different processing with non-standard magnetic track, non-standard parameter and key are write certain several sector, produce the special marking of encrypting floppy disk, the physical basis of Here it is copy protection.Whether work out a copy protection encryption software again, the special marking of floppy disk is carried out read-write operation, be the floppy disk through encryption to confirm this disc.If not, user software logs off.
Characteristics of the present invention are that encryption disc is made simply, do not need any utensil, floppy disk are not caused permanent mechanical damage, and the special marking of making has the anti-copy performance of height.According to encryption disc and the encryption software that the present invention designs and produces, can form a complete encryption system.The present invention and user program are are organically referred and synthesized, anti-copy effectively, and antitracking reaches the effect of protecting user's legitimate rights and interests.See Fig. 1.
The invention has the advantages that:
(1) encrypted running software must have the support of encrypting floppy disk, and encryption floppy disk not skewer is gone in the floppy disk, and its software can not put into operation, and the software that duplicates more can't use.
(2), to make the encryption disc material source extensive, without any specific (special) requirements, blank diskette or used disc all can be made into encryption disc.
(3) manufacturing process is simple, and cost is extremely low.
(4) scope of Jia Miing can be protected all .EXE files and .COM file than broad, also can be connected with the .OBJ file, constitutes encipheror, also can be embedded in the explanation type high-level language programs and data base management system (DBMS) in, form complete encryption system.
(5) encryption software is referred and synthesized in the user program with transparent mode, and the original function of encrypted program is had no effect.
Claims (6)
1, a kind of encryption method of floppy disk of anti-high-level copy software reproducer, it is characterized in that on the floppy disk of desire storage program, special format part magnetic track is inserted key parameter in having the sector of special format, and whether by encryption software floppy disk is differentiated be the read-write operation of encryption disc.
2, by the described encryption method of floppy disk of claim 1, it is characterized in that outside the standard magnetic track of floppy disk, the several magnetic tracks of extension format provide physical condition thereby insert key parameter in the sector for non-standard magnetic track.
3, by the described encryption method of floppy disk of claim 1, it is characterized in that, can make the diskette formatting magnetic track reach 48 by relevant instruction in the retouching operation system (DOS) and the program of formatting diskette.
4, by the described encryption method of floppy disk of claim 1, it is characterized in that making the instruction of magnetic track special format, utilize the disk drive and the interrupt instruction system of computing machine, floppy disk is carried out noncanonical format handle, make the CRC mistake.
5,, it is characterized in that encrypting and be equipped with encryption software on the floppy disk, and user program is suitably handled by the described encryption method of floppy disk of claim 1.
6, by the described encryption method of floppy disk of claim 1, it is characterized in that must moving earlier whether differentiation is the instruction of encrypting floppy disk before the encrypted running software, encrypted software leaves encryption disc and just can't move.
