Abstract

The invention provides a stamp with an anti-counterfeiting code. The stamp comprises a stamp body, a supporting frame and a stamp surface, wherein a hole is formed in the middle of the stamp surface; two arms of the stamp body are positioned in two arms of the supporting frame; springs are arranged in the two arms of the supporting frame, so that the stamp body can be quickly reset after being pressed at each time; and an anti-counterfeiting code generation mechanism capable of randomly generating different anti-counterfeiting codes is arranged at the position of the hole of the stamp surface, and is used for generating a group of anti-counterfeiting codes during stamping at each time and storing the anti-counterfeiting codes into a stamp chip.

Description

A kind of seal with security code and method for anti-counterfeit

Technical field

The present invention relates to a kind of security stamp, especially refer to have the security stamp of security code, this security code is random generation, and can be stored in seal chip.

Background technology

Seal is widely used in daily business, corporate business contact, various declare, examine all need to use seal.But counterfeit seal spreads unchecked in the market, to business activity, bring all multi-risk Systems.

There are in the market a lot of security stamps, have plenty of the number of registration of scribing enterprise on seal face; Have plenty of pattern or symbol with special identifier in the printing of seal body partner seal side; Also have some seals with anti-counterfeiting chip; But all there is certain leak in above-mentioned seal.As the number of registration of enterprise has been easy to inquire about now, do not there is security properties on the net; Although the pattern of special identifier or symbol have certain difficulty on copying, for the common staff of the departments such as bank, the tax, be also difficult to identification simultaneously, must could effectively identify by means of specific purpose tool, like this operating efficiency is also had to certain obstruction; And with the seal of electronic anti-fogery chip, because it belongs to precision equipment, crushing in the official seal of being everlasting is used, need to often change high cost.Therefore, the present invention, in order to solve the above problems, proposes a kind of seal with security code.

Summary of the invention

The invention provides a kind of seal with security code, the seal face, the Inkpad box that comprise a seal body, a bracing frame, a middle perforate; Described seal face tapping arranges one can produce different preventing pseudo-code generation mechanism and anti-counterfeiting chip at random.

Support frame as described above two arm inner bottom parts respectively set firmly a spring; Two arms of described seal body are positioned at bracing frame two arms, be connected and move up and down with spring.

Two ends, described seal face left and right are connected to seal body by two STHs on bracing frame, and the reversing device by being located at seal face inside is in the painted position of Inkpad box with affix one's seal and move up and down between file.

Described security code produces 5 swing pinions that are provided with numeral, letter, English, Chinese and symbol in mechanism, and 5 gear rows arranged side by side, produce one group of security code with each seal, are together imprinted on file with the face of printing Business Name.

In described seal face, an anti-counterfeiting chip is set, this anti-counterfeiting chip produces mechanism with security code and is connected, and each security code is produced to the security code storage of mechanism's generation and sends out by external interface or wireless mode.

Described bracing frame bottom is provided with the frame circle of a hollow out, and the radius of its frame circle is greater than the radius of seal face; When user holds handle, press downwards, seal face is just in time printed on file by frame circle.

Described seal plane materiel matter is rubber or metal.

Described seal body and the material of bracing frame are elected rubber and plastics as.

A method for anti-counterfeit that utilizes seal as claimed in claim 1, comprises the steps:

Step 1: during by impression body, print the corresponding Compress Spring of two arms of body, drive seal face by being located at the reversing device upset of seal face inside simultaneously, and move downward;

Step 2: after seal face starts, can drive built-in security code to produce the gear rotation in mechanism, thereby produce one group of new security code;

Step 3: when seal body two arms are compressed to spring bottom, seal face is also through the frame circle of bracing frame, and the word on seal face is imprinted on file together with the random security code producing;

Step 4: after new security code produces, anti-counterfeiting chip reads and store this security code, is sent to seal verification department by external interface or wireless mode simultaneously;

Step 5: put on record after this security code is received by seal verification department, and check at the security code of receiving after the material of affixing one's seal and put on record, with the authenticating documents true and false.

Security stamp provided by the invention, can produce one group of irreversible security code with seal use each time, in use, security code is clear, for bank, and the department personnel such as the tax, be convenient to identification, to reach the object of true and false identification, increase work efficiency; This security code produces at random simultaneously, not reproducible, and for not being the personnel that really contact official seal, security code is difficult to know, and avoids being imitated easily, has higher confidentiality; In addition, security code produces mechanism and is arranged on seal face perforate inside, is not vulnerable to extraneous damage, cost-saving.

Accompanying drawing explanation

Fig. 1 is the structure chart of seal of the present invention;

Fig. 2 is the structure chart that security code of the present invention produces mechanism.

The specific embodiment

Below by embodiment, further illustrate technical scheme of the present invention.

As shown in Figure 1 and Figure 2, a kind of seal with security code, the seal face 3, the Inkpad box 4 that comprise a seal body 1, a bracing frame 2, a middle perforate; Described seal face tapping arranges a security code that can produce at random different preventing pseudo-code and produces mechanism 5 and anti-counterfeiting chip 6.

Support frame as described above two arm 21,22 inner bottom parts respectively set firmly a spring 7; Two arms 11,12 of described seal body are positioned at bracing frame two arms, be connected and move up and down with spring.

Two ends, described seal face left and right are connected to seal body by two STHs on bracing frame, and the reversing device by being located at seal face inside is in the painted position of Inkpad box with affix one's seal and move up and down between file.
