Description
The present invention relates to the method for protecting software and the device of computer program, the Games Software program that is meant the protection electronic game machine especially is to guard against the counterfeit method and apparatus that duplicates.
In today that intellecture property is respected fully, electronic goods prevent that plagiarizing counterfeit is a very important problem.Present widely used electronic game machine system (TV gamesystem) uses fixing and standardized hardware main frame, is equipped with multifarious game software card, by user's hobby, can select various Games Softwares to play.Typical gaming software is stored among the memory integrated circuit card (memory IC catridges), can allow the user change on the hardware main frame of electronic game machine at an easy rate, so that conversion game type and content.
The software program data of electronic game machine is to be stored in the integrated circuit card, carry out by total line retrieval by the hardware main frame of canonical form because be, its contents of program data layout etc. also is the form of fixing, so its games content is easy to be plagiarized by counterfeit infringer and distorts.Because Games Software need drop into lot of manpower and material resources when exploitation; the work that cost is developed for a long time; and the counterfeit duplicator of usurping gives massive duplication after the cost time seldom; peddle at a low price and desire to make money or profit; hit the sale of master Games Software, therefore key subjects in the art promptly are how to protect the software program content to avoid deciphering to plagiarize.
With regard to the protection of program software; aspect electronic game machine; the home computer (FamiCOM) of the Nintendo Co. (Nintendo) of Japan has adopted the device of microprocessor as protection with super home computer (Super FamiCOM), is arranged at respectively in game host and the Cartridge.When system boot, two microprocessors just can relatively be proofreaded mutually, just stop the operation of Games Software if any incongruent situation.But, though the deciphering of this kind method will spend the bigger time,, just can be applied on the Games Software card of other kind as long as once decrypted.
On the other hand, the SEGA game machine computer system of Japan then is to add one section password in the storer of game card, and when system boot, the basic input/output routine of main frame can check whether this section password is correct, and a trade mark can appear, attempt to utilize trade mark to stop the counterfeiter.Though its password is handled through special, decipher and be not easy, light still is not enough to stop the counterfeiter who makes up one's mind and will encroach right with trade mark.
In addition; the PC Engine game machine computer system of the NEC Corporation of Japan then adopts comparatively special manufacture process on the memory integrated circuit in its software program card; the access speed of its storer is faster than general normal memory integrated circuit; so nobody can copy when just releasing; but after a period of time; the memory integrated circuit that reads fast is quite general, so its protective effect has also been lost.
Aspect PC, the protected mode of Games Software, in the scope of Games Software several PC in vogue, to widely used IBM PC, the method for protection software has been exactly variation by early stage apple two types (Apple II).But, the mode of these software protections still can roughly be sorted out as follows.
At first, be stored in Games Software on the floppy disk on disk, to surpass the format mode of usual standard, weak magnetic area for example, " seamless lock " etc. protected, so that disk is not easy to be duplicated by common people.Cost is cheap though this kind method is simple, can't prevent the imitated bootlegger's of specialty copy right piracy.On the other hand, the practice that this kind juggled things on disk has the disc driver compatibility issue, and disk is easy to damage, and makes slack-off etc. the spinoff of whole speed owing to the operation of software can need to retrieve floppy disk.
Secondly, also the someone uses the hardware interface card of what is called " pintle hook lock " (" key card ") in the art, is inserted in the system extension groove such as IBM PC computer, to carry out the protection of software program.The advantage of this kind pintle hook lock is that it duplicates and is not easy, and the speed of operation is also fast, is unlikely to because of adding pintle hook lock the carrying out of software program slowly to be got off.Its shortcoming then is, in the computer of IBM PC one class, the device of this kind pintle hook lock must be opened the shell of system host just and can carry out, and it installs inconvenient.In addition, compatible problem also may take place in this kind pintle hook lock between the main frame of different labels.And, also can't use the device of this kind interface cassette such as the computer of notebook type.
Other has a kind of mode, and similar protection lock " KeyPro " device of a kind of and aforementioned pintle hook lock is arranged in the environment of IBM PC, is inserted on the parallel port of system, carries out the program software defencive function similar to aforementioned pintle hook lock.Common KeyPro type protective device includes the T-Lock of Trend Technology Corp., the HASP of Aladdin Security company, the Sentinel of Rainbow Technologies company etc. in the present widely used technology.Therefore this type of KeyPro installs easily owing to be on the parallel port of the system of being installed on, and does not also take parallel port, therefore is a kind of convenience and actual protection hardware mode.But, because KeyPro still can increase the cost of hardware aspect, with regard to the Games Software program of general low price,, therefore also inapplicable because its cost ratio is higher.This kind KeyPro generally only sees the high professional software of price, among the scope such as softwares such as CAD/CAM.
Therefore keycard and KeyPro belong to effectively software program protected mode; it duplicates need higher professional knowledge, thereby is not easy, and with regard to Games Software; because the game card slot of electronic game machine is exposed to outer, therefore there is no the problem that difficulty is installed.
Though KeyPro belongs to comparatively effectively software program protective device, because the ultimate principle of its protection software is to utilize the code data that is stored among the KeyPro to carry out the protection of software program.The Games Software program before carrying out, system must check among the KeyPro password whether with software program in part meet.If the result who checks meets, the just normal executive routine of system, if do not meet, the execution of software program just is terminated.But, to make what be used for stored password be the read-only storage integrated circuit of an electro erasible programmable preface (EEPROM IC) that is arranged in the KeyPro to KeyPro.Because the integrated circuit that the electro erasible programmable preface read-only memory integrated circuit of formula mostly is canonical form is read in this serial, therefore to duplicate not difficulty especially.
Among software program prevents counterfeit pirate protection, particularly the present technique territory of the Console Game software program of a large amount of circulations of protection, the guard method that really can't not crack.A basic difference between all protected modes just cracks the complexity of protection, cracks the morning and evening of time, cracks the cost size issue that spends.Therefore the main points of software program protection by another angle, are to make to crack required cost cost increasing, and this has comprised the lengthening of the time of cracking, and imitated cost is increased, and so just can reach the counterfeiter is stepped back, and has reduced pirate target.
Therefore; an object of the present invention is to provide a kind of method for protecting software and device of computer program; particularly the Games Software programmed protection of electronic game machine prevents the counterfeit method and apparatus that duplicates; can utilize the mode of multiple intersection comparison to check whether the software protecting equipment that is comprised among the Games Software program card is intrinsic software protecting equipment, and with the foundation of comparative result as the execution of Games Software program.
