Description

Dynamic anti-fake method and microcomputer-recognized intelligent anti-fake label

The present invention relates to a kind of method and specific purpose tool thereof that prevents false prosperous low-quality goods.

At present, though known method for anti-counterfeit is varied, conclude main three kinds.First kind is to utilize fixedly that anti-false sign carries out false proof method, as the laser anti-counterfeit label.This method advantage is to install to make simply, and with the packing of product, profile is irrelevant, is suitable for all commodity; Shortcoming is this anti-counterfeiting technology in case grasped by the fake producer, has just lost antiforge function.Second kind is to utilize the packing of product to carry out false proof method, false proof as the alcohol product bottle cap.The shortcoming of this method is relevant with the packing of product, profile, different product, Different Package, different profile, and its false proof measure is not quite similar, and numerous false proof measures make the consumer at a loss as to what to do, and the chance of fishing in troubled waters is provided to the fake producer.Same this method for anti-counterfeit is in case just can be lost antiforge function by fake producer's grasp.The third is to occur the computer anti-false method recently.It is a coding of giving earlier different other commodity of each commodity, then the coding of all commodity is stored in computer system for consumer's inquiry of making a phone call or surf the Internet.This method has three shortcomings.It is cumbersome that one of shortcoming is that the consumer operates, and must hang a phone (most applications is trunk call) because of the consumer whenever buys commodity, or surf the Internet (being minority after all), just can inquire authenticity of products.Two of shortcoming is that consumer or manufacturer must charge for telephone (building in most cases is a toll charge).Three of shortcoming is, the inquiry of making a phone call or surf the Internet under the present circumstances is minority after all, much can not re-used by enquiry number so in addition, and this provides opportunity to the fake producer.

Purpose of the present invention has two.One of purpose provides a kind ofly carries out false proof method for anti-counterfeit with anti-false sign.This method is not only applicable to all commodity, and is irrelevant, simple to operate with commodity shape, packing, extremely difficult the forgery, even and this method grasped by the fake producer, can not destroy the antiforge function of other commodity.

One of purpose of the present invention is achieved in that at first designing a kind of is core with the micro computer, the software and hardware false proof device that combines, this false proof device can produce a kind of dynamic, variable anti-false sign, the false proof device that anti-false sign has same Changing Pattern is installed on all products of same brand or same class commodity again, provide correct anti-false sign by common transmission medium (as newspaper, radio and television, the Internet etc.) then, inquire about, contrast for the consumer, or provide the true and false of a kind of special-purpose recognition device identification product to the consumer.

Above-mentioned anti-false sign can show by display device, is disclosed.But the Changing Pattern of anti-false sign is through encryption, and it not only depends on the program of computer, and the person provides anti-forge cipher to depend on the production, so common people are Changing Patterns of there is no telling anti-false sign.Even the fake producer grasps this method for anti-counterfeit, know the Changing Pattern of certain class commodity counterfeit prevention sign, also can't know the Changing Pattern of the anti-false sign of other commodity, have no way of destroying other commodity counterfeit prevention function.Even the anti-forge cipher of certain class commodity is revealed, the production person also can reset password easily.

The way of realization of false proof device is varied.If this product is an electronic product, itself just has micro computer, and the software implantation that only needs to produce the dynamic anti-fake sign wherein gets final product.An also available single-chip microcomputer (MCU) is made an antifalsification label specially, is installed on the product.

Anti-false sign can be one group of arabic numeral, also can be a kind of color, or a kind of colored trade mark.Anti-false sign can change in time, and is unit with the real-time clock, as changing once one day or half a day, be convenient to like this on newspaper, announce, be convenient to consumer's inquiry, anti-false sign also can just have a corresponding anti-false sign with digital different change of input validation when a defeated checking is digital.

Two of the object of the invention is that a kind of dynamic, anti-false method specific purpose tool is provided.It can not only produce a dynamic anti-fake sign, has antiforge function, and has the true and false function of identification like product.

Two of the object of the invention is achieved in that microcomputer-recognized intelligent anti-fake label, and a kind of specific purpose tool of dynamic anti-fake method is a core with single-chip microcomputer (MCU) (1), single-chip microcomputer (1) input port external separation sensitive switch K ₂The clock correction K switch ₃K ₄The external anti-false sign display device of single-chip microcomputer (1) delivery outlet (2); Single-chip microcomputer (1) internal storage state determining program (3), anti-false sign generating routine (4), false proof crash handling subroutine (5), clock correction subroutine (6).Single-chip microcomputer also is provided with the power supply holding circuit in addition.

The contrast accompanying drawing is described further work of the present invention is former below

Accompanying drawing 1 is the microcomputer-recognized intelligent anti-fake label composition frame chart.

Accompanying drawing 2 is the main program flow block diagram

Separate sensitive switch K ₂Be installed in the microcomputer-recognized intelligent anti-fake label back side, and between the product, can be a pressure switch, or an optoelectronic switch, magnetic switch, when micro computer intelligence anti-fake label separates with product, separate sensitive switch K ₂Just closed, give the single-chip microcomputer low level signal.The clock correction K switch ₃K ₄Cooperatively interact and to proofread and correct the inside real-time clock of single-chip microcomputer, perhaps can import any arabic numeral and verify the true and false of anti-false sign by them.The anti-false sign display device can be LCD or LED display, or band look light emitting diode.The microcontroller power supply holding circuit is by power switch K ₁, transistor BG ₁, BG ₂, resistance R ₁, R ₂Form.When pressing power switch K ₁, single-chip microcomputer energising back is exported a high level P at once ₂Make BG ₁, BG ₂Conducting is with power switch K ₁Short circuit realizes the power supply self-insurance.At this moment if the microcontroller power supply that will break must unload battery, and power supply holding circuit, battery with separate sensitive switch K ₂Be contained in the microcomputer-recognized intelligent anti-fake label back side together.So unload battery, before the deenergization, separate sensitive switch K ₂Will move.She Ji purpose is in order to prevent that the fake producer from attempting by the deenergization mode, singlechip CPU to be shut down can not enter corresponding false proof crash handling program, and microcomputer-recognized intelligent anti-fake label is reclaimed like this.

State determining program (3) is a master routine, mainly is to judge that (x is E to specific memory cell x ²Whether the content unit in the PROM memory) is 1, separates sensitive switch K ₂Whether move, the clock correction K switch ₃, K ₄Whether move etc.If the content of memory cell x is not 1, separate sensitive switch K ₂Not action, CPU will carry out anti-false sign generating routine (4).If the content among the memory cell x is 1, CPU just enters false proof crash handling subroutine (5), if separate sensitive switch K ₂Action, CPU just earlier puts 1 with memory cell x, enters false proof crash handling subroutine (5) then.If clock correction K switch ₃, K ₄Action, CPU is with regard to entry time syndrome program (6).Anti-false sign generating routine (4) is a master routine, when carrying out this program, will read inner real-time clock data earlier or by the clock correction K switch ₃, K ₄The checking number of input provides anti-forge cipher to determine that compute mode and calculation step carry out computing to above-mentioned timing parameter or input number according to producer then, selects anti-false sign according to operation result at last, and exports and be presented on the display device (2).

When CPU carries out false proof crash handling subroutine (5), perhaps produce a false proof inefficacy sign and be presented on the display device (2).Return master routine again and carry out anti-false sign of anti-false sign generating routine (4) generation, be presented on the display device (2).Perhaps anti-false sign is carried out being presented at again on the display after certain particular procedure, show that as anti-counterfeit number being added or deducting redirect then returns the beginning of master routine, executing state determining program (3) after the certain number again.So just not carrying out the anti-false sign generating routine produces anti-false sign again, and false proof inefficacy sign can be Chinese characters such as " false proof inefficacy ", " scrapping ", also can be specific sign.

When carrying out clock correction subroutine (6), CPU not only revises internal clocking with the clock data of outside input, the checking number of outside input is offered anti-false sign generation subroutine (4), but also will limit the number of times of external clock and the digital input of checking, limit the scope that clock is revised.For example anti-false sign is to change unit with the sky, when using power-on for the first time, can proofread and correct outside the year, month, day so, At All Other Times can only position, minute, anyone can't predict second day anti-false sign like this.But when battery runs low,, still can guarantee the accuracy of year, month, day, because of parameters such as year, month, day have been stored in single-chip microcomputer E as long as the user can change battery in 24 hours ²In the PROM memory.Perhaps allow CPU monitor the duty of battery, the chance of once revising year, month, day will be provided when battery will use up.

Microcomputer-recognized intelligent anti-fake label except that above-mentioned false proof and two kinds of functions of identification, also can utilize memory function storage product raw data, as production date, tenure of use, product operation instruction or the like.
