Abstract

The utility model relates to an anti-counterfeiting seal, which comprises a seal holder and a seal surface, wherein the seal surface is engraved with outer margin lines, characters and / or specific patterns, and the outer margin line is engraved with grooves having different width to form lines being similar to bar codes. The encoding of the lines being similar to the bar codes is determined by the random number, and the depth of the groove is basically same with the depth of the outer margin line. The utility model is difficult to be counterfeited no matter manual engraving manufacture or engraving manufacture by machine, can use the existing bar code identification technique and the computer network to rapidly and exactly identify the true form false of the seal without changing the structure, the pattern and the use method of the existing seal. The utility model has the advantages of convenient use and clear printing track, and the cost is basically same with the existing seal.

Description

Security stamp

The utility model relates to a kind of security stamp.

Existing all kinds of seal, regardless of its shape, manufacture craft how, its chapter face is generally all by border line, literal and/or special pattern constitute, therefore from having the structural analysis of seal now, itself does not possess false proof ability its seal, no matter be that mechanical injection moulding or machine are made or manual scribing, it is identical or basic identical with former seal that the personation seal all can be made, therefore, all kinds of behaviors of breaking laws and violate discipline that caused by the personation seal make the authority of all kinds of seals be subjected to serious threat, and its due legal right can not get conventional maintenance, so and all kinds of cases of initiation emerge in an endless stream.

Classify from the preparation method of seal, have machinery or machine to make and make by hand two kinds of methods, the seal that machinery or machine are made is attractive in appearance, beautiful, the neat standard of font, and manufacturing speed is fast, cost is low.Just because of its neat standard, make its anti-counterfeit capability very poor, the personation seal can be done identically with former seal.The seal that craft is scribed, font is lack of standardization, aesthetic measure is poor slightly, manufacturing speed is slower, but its anti-counterfeit capability is stronger, want with the identical of former making stamp be that comparison is because of difficulty, but along with progress of science and technology, engrave a seal by hand by Hand writing excessively to computer printout or duplicate original trace, again by certain technical finesse and then manual scribing, the improvement of the means that carve a seal makes the manual seal of scribing anti-the making of also being not difficult.

For the authority of protecting seal, the legal sanctity of safeguarding seal; China all takes administrative method in various places now; (especially official seal) must be held and close the unit reference and put on record to local public security department when seal was made in printing; hold the reference of public security department after the agreement of acquisition public security department and scribe seal to the place of its appointment again; therefore the industry that carves a seal has become a kind of special industry in China; be subjected to the special management of country; yet sail down driving of economic interests, only depend on administrative means to be difficult to stop to palm off seal.

The purpose of this utility model is to utilize existing bar code identification technology, and a kind of security stamp of design under the condition that does not change existing seal basic structure, style and using method not only is difficult to copy, and the true and false of identifying stamp fast and accurately.

The utility model design: a kind of security stamp, comprise chapter holder (1) and chapter face (2), be carved with border line (3), literal and/or special pattern (4) on the chapter face (2), be carved with the groove (5) of different in width on the border line (3), constitute and to be similar to the lines (6) of bar code, and the coding that is similar to the lines (6) of bar code is determined by random number.The degree of depth of the degree of depth of groove (5) and border line (3) is basic identical.

Advantage of the present utility model and effect:

1, owing to is carved with the groove lines that different in width is similar to bar code on the border line of the present utility model, and its coding is determined by random number, scribe and to forge by hand, even same machine also almost can not scribed two pieces of identical seals when machine was scribed, therefore can play effective anti-fake effect.

2,, not only make manually and differentiate that by naked eyes the true and false ratio of seal is easier to, and can utilize existing bar code identification technology and computer network to differentiate the true and false of seal fast and accurately because the border line of the trace that the utility model covers out is similar to bar code.

3, the utility model does not change basic structure, style and the using method of existing seal, and therefore easy to use, trace is clear, and cost is basic identical with existing seal, is easy to popularization.

Fig. 1 is the structural representation of first kind of embodiment of the utility model;

Fig. 2 sees figure for bowing of Fig. 1;

Fig. 3 is the structural representation of second kind of embodiment of the utility model;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is the trace of first kind of embodiment of the utility model;

Fig. 6 is the trace of second kind of embodiment of the utility model.

Embodiment 1: Fig. 1, Fig. 2 are first kind of embodiment of the present utility model, constitute by chapter holder (1) and chapter face (2), be carved with square border line (3) and literal (4) on the chapter face (2), be carved with the groove (5) of different in width on the border line (3), constitute the lines (6) that are similar to bar code, and the coding that is similar to the lines (6) of bar code determines that by computer random the degree of depth of the degree of depth of groove (5) and border line (3) is basic identical.

Preparation method: computer carve a seal system by computer, seal scribe software, engraving machine three parts are formed.Now as long as change the existing software that carves a seal, making it scribe in the process groove of scribing different in width on the border line at seal at seal gets final product again, promptly be similar to the lines (hereinafter to be referred as the class bar code) of bar code, the coding of class bar code is determined by random number, carving the seal that comes so almost can't copy by manual, even on same machine, also can not carve two pieces of identical seals, because the bar code of seal edge line is to be produced by random number, if the bar code on the opposite edge line is determined by specified coding, use same machine just can carve identical seal so, do not have its due imitative pseudo-effect.

Recognition methods: security stamp mainly is to have increased the lines that are similar to bar code on the border line of existing seal, this automatic discriminating for seal provides advantage, can adopt multiple way to differentiate the true and false of seal, be relatively easy to even manually differentiate also by naked eyes, two kinds of ways now are provided: 1. we can utilize existing bar code identification technology, being the class bar code with the lines on the security stamp trace border line reads with the form of coding, again with database in the coding of the security stamp that stores compare to differentiate the true and false of seal; 2. the trace of seal is gone in the computer by scanner scanning, compare, to differentiate the true and false of seal with the trace that stores in the computer.This shows that the security stamp recognition system should be made up of computer, code reader or scanner, security stamp identification software and necessary network communication equipment.

After security stamp is scribed and finished, put on record or reserved specimen seal (these departments should have corresponding security stamp recognition system) to relevant department, we just can differentiate the true and false of seal fast and accurately again.If share for the whole society by computer network through the security stamp of putting on record, just it is available nowhere to palm off seal so, thereby can safeguard due legal sanctity of seal and legal status effectively, ensure the uniqueness and the authority of seal.
