Description
Technical field：
Invented the present invention relates to the anti-counterfeiting technology of credit file, more particularly to Chinese invention patent ZL200710121845.6
The a kind of of the technical scheme of entitled " credit sign accidental streakline generating method " prevents the illegal mobile side using credit sign
Method.
Background technology：
Chinese invention patent ZL 200710121845.6, entitled " credit sign accidental streakline generating method "
Patent, following explanation has been done in background technology：
" human society is needed to carry out interests exchange between men, and interests will be often used with credit mark in exchanging
Voucher, i.e., we generally say " sealed files " or " signature file ".
Chinese Government provides " file, which is affixed one's seal, to come into force ", has substantial amounts of file to affix one's seal in government work, the commercial work of enterprise
Also there is substantial amounts of contract to affix one's seal in work.
Also there are such regulation in other countries, such as using seal or insignia, or use idiograph.
In daily life, our common seals or insignia are to represent a unit, mechanism or personal, this
Seal or insignia in use, simply show the title of a unit, mechanism or personal, with the file content being signed
There is no any contact.
Conventional idiograph does not have any Statistical contact with identified file content yet.
Seal recited above, insignia, or idiograph, we can be referred to as them " credit sign ".
In high-tech structures such as modern high-precision scanner, Computer Image Processing software, automatic carving machine, light sensitve exposing machines
In face of, seal, insignia are very easy to scanned duplication, forged, and the pattern replicated is consistent, it is impossible to differentiate.
Idiograph is also can be with echographia, so that hard to tell whether it is true or false.
In the promotion and implementation of globalization E-Government and ecommerce, the credit that tradition can be affixed one's seal with idiograph
Identification method is combined in the computer information system of office, using Electronic Signature mode, seal, insignia, idiograph
Electronic image files are injected in e-file, then make the picture and text printing equipment (such as color printer) computerizedd control this
It is individual that there is seal, insignia, the e-file of idiograph to print out.
But, seal, insignia, the electronic image of idiograph signed under this method are once printed on paper document
On, also easily it is scanned replicating and can not discerning the false from the genuine.”
Above is Chinese invention patent ZL 200710121845.6, entitled " credit sign accidental streakline generation
The patent background technology explanation of method ".
The problem of duplication, movement being illegally duplicated for solution credit sign to use, and then forge credit document, Chinese invention
Patent No. ZL 200710121845.6, the patent of entitled " credit sign accidental streakline generating method " provide a kind of letter
With sign accidental streakline generating method, credit sign pattern of the signature on paper can be made to carry with uniqueness pattern characteristics
Digital signature random number code streakline, so as to effectively prevent, differentiate, hit the illegal act for forging credit sign.
The method of the patent is：The data signal of digital signature is converted into analog signal, then with exclusive credit sign
Analog signal overlap together, generation uniqueness " streakline " method；Realize " line one of a chapter one is close ", and then complete exclusive letter
The problem of being used and forged with the anti-illegal movement of mark, the anti-counterfeiting technology is applicable not only to seal, is also adapted to idiograph.
The patent illustrates authenticity verification method in the content of embodiment, in four steps：
Anti-fake check step is as follows：
The first step：Set scanner 600DPI and more than, RGB color scanning seal impression.
Second step：The printed text image that scanning is obtained is checked in amplification, is seen if there is streakline track, is not considered as forgery：If
Have, continue.
3rd step：The e-file of credit sign file or the hashed value of file plain text content are obtained, credit mark is used
This hashed value of the asymmetric-key encryption of digital certificate of knowledge unit, joins according to the generation of credit sign " digital signature streakline "
Number and rule, regenerate " the digital signature number streakline " for this credit sign.
4th step：Make this group " digital signature random number code streakline " and be laminated on above the credit sign for needing to verify,
The situation that streakline track is overlapped is observed, it is true that streakline track, which overlaps then credit sign (such as seal),.
Above is Chinese invention patent ZL 200710121845.6, entitled " credit sign accidental streakline generation
The checking procedure of the patent of method ".
Credit sign mainly includes " sign, affix one's seal ".The specification pattern of east and west seal is usually national regulation or agreement
Custom into, then add legal entity's title with literal meaning, this legal entity's title be prove " credit sign " specially
The fundamental of attribute, is the word or alphabetical group by being constituted compared with thin stroke.The specificity of idiograph's person's handwriting is personal book
Style is write, without specific code requirement, daily signature typically uses the writing signature pen of 0.3-0.5 diameters, and stroke writing
Also there is thickness change with artistry.
Digital signature in information security technology system, is to use hexadecimal numerical code expression, i.e., " 0,1,2,3,4,5,6,
7、8、9、A、B、C、D、E、F”。
It is difficult that hexadecimal number is write into the specificity strokes of characters of credit sign.For example, 0.3 mm dia
Only 0.3 millimeter of the strokes of characters that writes out of signature pen it is thick；International printing equipment uses the color separation of 300DPI resolution ratio
Site, a color separation site (or referred to as pixel) is 0.00846 millimeter, is approximately 0.01 millimeter, 0.3 millimeter of thick strokes of characters
Need 3 color separation sites to represent, a hexadecimal number is told in a stroke, minimum 7 pixels of needs
Space, such as alphabetical " E ", and the number that 5 pixels are constituted is write in the space of 7 pixels, the credits such as handwriting signature can be destroyed
The external appearance characteristic of mark.
But, if can from the specificity mark of the credit sign of " signing and sealing ", i.e., in strokes of characters in, directly carry
The hexadecimal for taking out digital signature in information security technology system is digital, it is possible to reduce the step of anti-fake check, directly, fast
It is prompt.
Above-mentioned technique effect can not be realized using existing known technology.
