Abstract

The utility model discloses an IC main control chip of a card reader, which comprises an IC main control chip body, a central controller positioned on the body and a software identifying module for identifying external software; the central controller is connected with the software identifying module. The IC main control chip of the card reader has the advantages of low manufacture cost and convenient use and operation, includes the functions of resisting copy and discerning the identity on the basis of not losing the original functions, and can serve the functions of discerning the identity and resisting copy of the software in a personal computer or other devices under the circumstances that can be afforded by general customers.

Description

A kind of card reader IC main control chip

Technical field

The utility model relates to the card reader field, but particularly a kind of card reader IC main control chip with recognition function.

Background technology

Along with the continuous progress and development of society, PC becomes an indispensable part in work, the life gradually, and the raising of PC frequency of utilization makes PC data, individual software document seem particularly important; Prevent the user when not obtaining the corresponding right to use, use PC or software, just need the protection PC not by without the start of allowing and software not by safeguard measure without the anti-pirate of allowing.At present, the multiple safeguard measure of copying at PC data or software anti-theft is also arranged on the market, but the high device of manufacturing cost is used in these identification measures mostly, and complex structure, make the general unable purchase of consumer of using PC; And the most common computer cipher control start if carelessness forgets Password and then is difficult to start, or resets, and makes troubles to the user.

The utility model content

The purpose of this utility model provides a kind of identification of the software in PC or the miscellaneous equipment and card reader IC main control chip of anti-pirate function realized.

A kind of card reader IC main control chip that the utility model provides, comprise IC main control chip body, be positioned at the software identification module that a central controller and on the described body is used to discern external software, described central controller is connected with described software identification module.Described software identification module further comprises data transmit-receive module, data processing module, data decode module; Described data reception module is connected with described data processing module, and described data processing module is connected with described data outputting module.

But the software recognizer in the card reader IC main control chip that recognition function is arranged that the utility model provides can be stored in first validation signal that software in other modules of card reader or the software in other external units sends and trigger; Data reception module receives first validation signal that described external software sends by IC main control chip central controller in the described software identification module, after described data processing module reads first validation signal, computing generates second validation signal that can start external software with first validation signal one to one, and data outputting module exports second validation signal that data processing module generates to external software.

The utility model places the IC main control chip of card reader with the software recognizer, has realized by card reader the software in PC or the miscellaneous equipment being carried out the purpose of identification and anti-pirate.

Description of drawings

But Fig. 1 a kind of structural representation that is the utility model with card reader IC main control chip of recognition function.

Embodiment

See also Fig. 1, but a kind of card reader IC main control chip with recognition function, comprise IC main control chip body 2 and be positioned at the software identification module 3 that a central controller 4 and on the described IC main control chip body 2 is used to discern external software, described central controller 4 is connected with described software identification module 3.

Software identification module 3 comprises data reception module 31, data processing module 32 and data outputting module 33; Described data reception module 31 is connected with described data processing module 32, and described data processing module 32 is connected with described data outputting module 33.

When using card reader, start the specific software in the external unit this moment if desired, card reader is inserted in the external unit, described specific software sends first validation signal to this card reader, when the IC main control chip receives described first validation signal, the data reception module 31 that the central controller 4 of IC main control chip will be controlled the software identification module 3 in this IC main control chip receives first validation signal that described outside specific software is sent, data processing module 32 reads the software recognizer that starts this inside modules behind described first validation signal and generates second validation signal according to the first validation signal computing that described data reception module 31 receives, and described first validation signal is the signal (first validation signal can be character string identifying code or digital verification sign indicating number) that external software produces at random; Described second validation signal and described first validation signal have relation one to one.Data output unit 33 exports second validation signal that data processing module 32 generates to described outside specific software by central controller 4, to start described outside specific software.When external software is software with card reader coupling, second validation signal according to described first validation signal output is the signal that can start described outside specific software, if described external software is pirate or non-adapting software, first validation signal of described external software input is wrong validation signal, according to second validation signal of described first validation signal output also mistake, at this moment, can find the external software mistake.Therefore, the utility model can be realized the identification and the anti-pirate function of the software in PC or the miscellaneous equipment.

For example, when needs start an outside animation software, described animation software sends first validation signal " 101 " to this card reader, after IC main control chip 2 receives described validation signal " 101 ", the data reception module 31 that the central controller 4 of IC main control chip will be controlled the software identification module 3 in this IC main control chip receives first validation signal " 101 " that described outside animation software sends, the software recognizer that data processing module 32 reads this inside modules of described first validation signal " 101 " back startup generates second validation signal " 202 " according to the first validation signal computing that described data reception module 31 receives, data output unit 33 exports second validation signal " 202 " that data processing module 32 generates to described outside animation software by central controller 4, to start described animation software.If described animation software and this card reader coupling can start described animation software by described second validation signal " 202 ".

Outside specific software can be according to software developer's production requirement, be disposed in other modules of card reader or external unit, as in the CD or in the smart card, the effect that is reached is identical, and being used of software and card reader suppressed the copy right piracy on the market to a certain extent.

Card reader IC main control chip low cost of manufacture of the present utility model, use easy to operate, on the basis of not losing original function, increase anti-pirate and identity recognition function, can under the situation that mass consumption person bore, realize the identification and the anti-pirate function of the software in PC or the miscellaneous equipment.

Above disclosed only is the utility model preferred embodiment, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
