Abstract
An antiforge ink able to memory antiforge code, its detector, and its detecting method are disclosed. Said ink contains magnetic material for memorizing the antiforge code. Its detecting method includes such steps as using said detector to scan the ink trace of seal for sensing the magnetic information, magneto-electric conversion, amplifying, comparing the scanned information on that stored in IC, determining if it is true or false, and sending the false signal to alarm.
Description
Technical field
The present invention relates to a kind of stamp-pad ink of affixing one's seal and using, particularly have the anti-counterfeiting stamp ink of memory cipher and detector and the detection method thereof that the trace seal that uses this stamp-pad ink to affix one's seal is detected.
Background technology
The anti-counterfeiting technology of stamp-pad ink has following several principal mode at present: 1, adopt the fluorescence falsification preventing material to make, detect with ultraviolet light; 2, adopt temperature to become material and make, detect with temperature variation; 3, adopt magneticsubstance to make, use the power in instrument detecting magnetic field or the like.96104762.3 1 kinds of anti-forgery penetrant atomic stamp pad inks of Chinese patent (application number) and preparation method thereof, Chinese patent (application number) 98119855.4 multifunctional antiforge stamp-pad ink manufacture method, Chinese patent (application number) 99125133.4 length ripple anti-counterfeiting stamp inks and anti-forgery ink etc., mainly be to take in stamp-pad ink, to mix luminescent phosphor, shine with the trace seal of ultraviolet light then stamp-pad ink, utilize the fluorescence reverse signal to judge its true and false of identification, the weak point of this technology is that this technology detects just whether fluorescent material is arranged in the trace seal, such technology is imitated easily, only need when making stamp-pad ink, to mix fluorescent material and just become, be forged easily.Japanese Patent JP56115288 has introduced a kind of ink paste of making of temperature reversible color material, the trace seal that utilizes this stamp-pad ink to affix one's seal is met thermo-color, reach false proof purpose with this, to be the imitator mix when making stamp-pad ink the weak point of this technology that temperature becomes material has just become, and still is forged easily.Chinese patent (application number) 9710137.5 magnetic stamp-pad ink and seal anti-false instrument thereof, it has been introduced and has a kind ofly responded to its magnetic signal by mix magnetic in stamp-pad ink with a kind of instrument of magneticinduction, and the power that detects magnetic field is judged the true and false of its trace seal of identification.The weak point of this technology is the power that is to detect magnetic field, because a lot of reasons all can change the power in magnetic field in the trace seal in the daily life, thereby judges that with the power that detects magnetic field the confidence level of its trace seal authenticity of identification is not high.Above-mentionedly enumerate existing stamp-pad ink anti-counterfeiting technology and exist and imitated by the people easily or problem such as the confidence level of detected result is not high.
Summary of the invention
In order to overcome the weak point that existing stamp-pad ink anti-counterfeiting technology exists, the invention provides and a kind ofly be difficult to imitatedly, be easy to discern the anti-counterfeiting stamp ink with memory cipher of its trace seal authenticity and detector and the detection method thereof that the trace seal that uses this stamp-pad ink to affix one's seal is detected again.
The false proof transfer paper of the present invention is achieved in that
1, earlier magnetic memory material being crushed to particle size is below 2 ' 10-2 micron, magnetizes.
2, import encrypted message by electromagnetic conversion to magnetic memory material then, for example: F transfers 2 sound in the range, makes in each particulate magnetic memory material and all remembers the encrypted message that same content is arranged.
3, get magneticsubstance 10-30 part (weight ratio, as follows) of containing encrypted message, promoting agent 1-10 part, pigment 10-40 part, synthetic resins 20-50 part is mixed and processed colorant.
4, get colorant 20-40 part, thinner 30-70 part, auxiliary agent 0.1-3 part mixes them with mixing kettle or colloidal mill, is ground to less than 15 μ with three-roller or sand mill or ball mill or colloidal mill again, promptly makes the anti-counterfeiting stamp ink with memory cipher.
Described magnetic memory material is a magnetic conduction good metal oxide compound, this magnetic memory material can be that nature generates, it also can be synthetic, it can store the electromagnetism encrypted message of input and can preserve memory and can distinguish the electromagnetism encrypted message by instrument, this magnetic memory material comprises ferric oxide, manganese oxide, ferric oxide, manganese oxide, the cobalt oxide of cobalt oxide or adding rare earth material are as Fe
