Description

The protection of TV game software technique system and method thereof

Described technical field:

The present invention relates to Software Protection Technique.

Background technology:

Present widely used electronic game machine system uses fixing and standardized hardware sovereignty, is equipped with multifarious game software card, by user's hobby, can select various Games Softwares to play.Software is as a kind of invisible product, the hard-working of having condensed the developer, however the software of open platform almost just is subjected to the puzzlement of problem of piracy from beginning, and the bootlegger usually can allow software vendor can't regain one's original capital.The software systems of underlying network (comprising LAN (Local Area Network) and the Internet), its system architecture mainly comprises two types on C/S structure and B/S structure, can make full use of the advantage of two ends hardware environment by these two kinds of structures. the task reasonable distribution is brought in realization to client or server, reduced communication-cost.

Typical gaming software is stored in the memory integrated circuit card, 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 integrated circuit because be by the hardware main frame of canonical form by total line retrieval carry out claim its contents of program data layout etc. also be the form of fixing therefore its games content be easy to be plagiarized and distort by counterfeit infringer.Because Games Software the time need drop into that the great amount of manpower thing is done work that cost develops for a long time and the counterfeit duplicator of usurping gives massive duplication and peddles at a low price after the cost time seldom in exploitation, the sale of having hit the master Games Software therefore in the art key subjects promptly is how to protect that the visitor avoids the deciphering plagiarism in the software program.Adopted the device of microprocessor as protection, be arranged at game machine sovereignty and Cartridge system respectively, the situation that microprocessor relatively meets mutually just stops the operation of Games Software.Though but the bright sense of this kind method will spend the bigger time but as long as on the decrypted Games Software card that just can be applied to other kind in a year.The game machine computer system 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; but the continuous fast memory integrated circuit of getting is quite general after a period of time, so its protective effect has been lost.

Main contents:

The Games Software programmed protection of electronic game machine prevents the counterfeit method and apparatus that duplicates to the method for protecting software that fundamental purpose of the present invention provides a kind of computer program with installing particularly.

Technical solution of the present invention: the typical structure of the Games Software game hostization of the stores games software of operating software games has mainly comprised central processing unit, audio process, storer, and TV signal synthesizer.The Games Software cartoon often includes the software protecting equipment that the storer of store software programs and some system do not have in, some system; software protecting equipment when device at a Games Software card, receive address such as data and the control signal that the computer game system is sent as the protective device of software code.

Beneficial effect of the present invention:

Prevent the guard method that counterfeit pirate protection particularly protects the electricity of the present technique territory of a large amount of Console Game software programs that circulate really can't do not separated at software program.All protected modes with the basic difference complexity of just being separated protection spent the cost size issue by separating by the morning and evening of the time of separating and therefore software program protect to always just be separated required cost cost to strengthen the lengthening that this has comprised the time of being separated by another angle; imitated cost is increased so just can reach steps back the counterfeiter, has reduced pirate target.

Embodiment:

Including one counts to signal generation apparatus and can produce the dead signal of a number under the triggering of each time pulse: in order to the producing method of the dead signals of selected number and interface circuit provide with main system between be connected.At these element selecting arrangements can be that a memory storage such as erasable and programmable program only renews reservoir or electro erasible programmable preface ROM (read-only memory) or is applied to the programmable of integrated circuit, decoding device, data buffer and other device.The circuit of generator is one 5 a random number generator, and wherein to be connected in turn to trigger be that the time clock input of five all triggers of first trigger output input of being connected to next trigger and input are provided with respectively and are driven by signal for five D.Trigger is then imported by another exclusive or logic gate with the input trigger output that output is connected to an exclusive or logic gate.CPU (central processing unit) detects by the interface arrangement utilization under the control of program that the comparison means monitoring is continuous gets the time that potential state calculating voltage that described input and output breathe heavily mouthful charges to predetermined potential: the continuous result who gets the potential state that described input and output breathe heavily mouthful judges whether the duration of charging characteristic of described external charge time Control Component meets predetermined result with CPU (central processing unit) utilization monitoring, make the execution of ending software program, or the program of execution error makes the undesired execution of program.The end that described input and output are breathed heavily mouthful be not link to each other with external charge time Control Component but with one external discharge time Control Component link to each other.CPU (central processing unit) under the control of program by the described interface arrangement of described software protection locking device, be connected to described input and output breathe heavily on the mouth described external discharge time the electric capacity in the Control Component by to power supply potential so that electric capacity is seen that by rapid charge described switching device shifter is in conducting a period of time.The circuit of typical case's TV game machine system can be divided into two main portions; it is the Games Software cassette disk recreation of the game host and the stores games software of executive software games; the guard method of software program of the present invention can utilize comprising the external time Control Component that discharges and recharges that one section program utilization order with inspection effect is external on the input/output port on the Games Software program disc type disk among the Games Software program carries out the action of charge or discharge because the variation of time response; it almost is impossible almost having unlimited combination therefore will predict the time response of " lock " and be copied among rational accuracy rating, and this just can reach the purpose of software protection.
