Description
Technical field
The present invention relates to a kind of structure of seal, especially a kind of improvement of enciphered signet belongs to the seal field of anti-counterfeit technology.
Background technology
As everyone knows, seal mainly is made of the seal literary composition and the seal frame of bottom surface, is important right, identity documents.Carving seal, forgery value document and ticket without permission is that delinquent one's share of expenses for a joint undertaking is carried out the illegal activity conventional means.In recent years, the control of stamping problem is day by day serious, and the illegal activity of falsification of seal happens occasionally, show thus traditional seal use and print civilian recognition methods be out of step with the times the development paces.
In order to change the backward situation that seal used and printed literary composition identification, people are carrying out useful exploration along following two approach:
On the one hand, invented the intelligent optical instrument that seal is shot with video-corder Jianzhen's instrument and so on,, after the input computer carries out necessary image processing,, differentiated and judge the true and false with the standard seal comparison of storage by picked-up seal image.Though this method can be discerned the falsification of seal that naked eyes are difficult to differentiate to a great extent, cause erroneous judgement because of the misoperation of affixing one's seal easily.
On the other hand, by encryption technology traditional seal is carried out false proof transformation.For example, application number is that the Chinese invention patent application of CN200410014384.9 discloses a kind of holography from taking move database concealed-enciphering machine readable method for anti-counterfeit.It is introduced that this method can be carried out holography from taking the move database concealed-enciphering to seal etc., comprise that the compression of use computer, the characteristic information that carrier is put down in writing in encryption are stored in computer database system after encryption; Utilization sign indicating number anti-counterfeiting technology becomes characteristic information into one or more encrypting databases, read with corresponding recognizer, encrypting database is a self-carrying, but the database information multilayer is overlapping to be covered on the carrier or individual layer is distributed on the carrier simultaneously, with photochemistry or black light hide information, the information on the carrier adopts holographic technique.Therefore these class methods are distinguished password and can be discerned the false from the genuine because seal has been carried out special encryption.Yet these encryptions are not merged in the seal original structure, often need to set up special recognition instrument, therefore are difficult to apply.
Summary of the invention
The objective of the invention is to: at the problem of above prior art existence, a kind of two-dimensional encrypted seal that enciphered message and physical seal are organically combined is proposed, thereby both had desirable anti-counterfeiting performance, avoided erroneous judgement again, and made it obtain practical applying.
In order to reach above purpose, two-dimensional encrypted seal of the present invention comprises seal literary composition and the seal frame that is engraved on the seal bottom surface, and its improvements are: described seal frame is made of two circle interval concaveconvex structures of the specific two-dimensional matrix coded message of correspondence (abbreviation two-dimension code).
Adopt the reason of two-dimension code to be, seal frame area very little (width has only about 1.2mm usually), if adopt one-dimensional coding, code change is not enough to put down in writing required relevant information very little; And dimension too high (for example more than the triplex row) will cause the information point density of frame in unit are excessive, corresponding information is read become difficult.Rationally adopt two-dimension code can contain required encrypted message, the difficulty of scribing of seal is suitably increased, need special equipment, be difficult to copy, and can be on the basis that original comparison is differentiated, distinguish true from false by the recognition 2 D code information of back seal block diagram in resembling of impressing, thereby obtain desirable anti-counterfeiting performance, the erroneous judgement of avoiding simple figure comparison to cause is promoted easily.
Of the present invention further improving is that described two-dimensional matrix coding contains following information:
Seal applying unit organization mechanism code;
The making stamp time;
Making stamp unit organization Institution Code.
Above information is specific digital information, not only itself have certain confidentiality, and be easy to convert to two-dimension code, but the concaveconvex structure saturation is identical substantially at interval for its information content two circles corresponding with the seal frame, therefore be beneficial to the raising anti-counterfeiting performance, be convenient to implement.
It is that described two-dimensional matrix is encoded to the two-dimension code through encryption that the present invention further improves.Obviously, so more strengthened the anti-counterfeiting performance of seal.
In a word, the customizing messages of the present invention by will be relevant etc. directly is documented on the seal frame with concavo-convex image appearance form by the digitlization means, information technology and traditional seal are combined, thereby prevent to carve without permission forgery behavior such as seal, improve the sincere degree of government affairs commercial affairs.
