Problems solved by technology

[0002] At present, it is difficult to inspect the seal, because the difference in the printed text will also appear due to the aging of the texture, ink clogging, replacement of ink, difference in the physical properties of the liner and paper, and uneven force of the stamper during use. Explanation; and counterfeit seals due to more use of advanced technologies such as optics, holography, and plate making in modern photography, but also use computer compression and encryption technology, and some engraving professionals have also participated in counterfeiting official seal activities, etc., making forged seals The craftsmanship is becoming more and more standardized, and the technology is becoming more and more sophisticated. It is difficult to distinguish the formed seal from the real stamp seal.
In the traditional inspection, the external features such as uneven lines, uneven marks and images, and different symbols with the same meaning are becoming less and less obvious
The simple printing process of existing seals leads to fewer and fewer features of each seal, too few anti-counterfeiting functions, and technically unreliable identification, which brings difficulties to inspection and also brings opportunities for forgers machine
[0003] The applicant has a prior patent application, the application number: 200410014384.9, the application date: March 22, 2004; the name of the invention: a machine-readable anti-counterfeiting method for holographic self-carrying mobile database invisible encryption, the invention patent discloses an anti-counterfeiting method : It combines the original anti-counterfeiting technology with modern high-tech anti-counterfeiting technology to form a multi-coverage carrier information that can be uniquely identified by invisible light, invisible, movable, holographic, encrypted, and self-contained encrypted database-style machine-readable Anti-counterfeiting methods, and use computer systems to realize electronic and networked comprehensive management, but the disadvantages of this anti-counterfeiting method are complex implementation schemes, high technical requirements, high cost of implementation, and the need to use special readers to obtain information

Embodiment 1

[0015] Anti-counterfeiting method for corporate check seals: integrate account holder's relevant information, encryption algorithm (digital certificate), compression algorithm and clock circuit into one device (cipher generator) or computer software plus hardware key. When issuing a check, the enterprise enters the check number, amount, etc. into the password generator, and after the calculation of the password generator, a unique password including the clock and information is obtained, and the password is reflected on the check.

[0016] Passwords can be numbers, letters, symbols or a combination of them. The code can be reflected on the check by means of a separate wheel stamp or a special stamp with a wheel stamp. The dynamic code imprint can be reflected on the check in multiple colors or in an invisible way. Invisible patterns are applied here to ensure that the seal fully complies with the State Council's regulations on the shape, size, font, and pattern of seals. The...

Embodiment 2

[0022] Anti-counterfeiting method for official seals: Integrating unit related information, encryption algorithm (digital certificate), compression algorithm and clock circuit into one device (cipher generator) or computer software plus hardware key. When the official seal is used, enter the user's ID card and other relevant information into the password generator. After the password generator calculates, a unique password including the clock and information is obtained, and the password is reflected on the seal.

[0023] Passwords can be numbers, letters, symbols or a combination of them. The reflection of the password on the seal can be achieved by a single wheel stamp or a special seal with a wheel stamp. The cipher imprint can be reflected on the carrier in various colors or invisible. Applying the invisible pattern here can ensure that the seal fully complies with the State Council's regulations on the shape, size, printed font, and pattern of the seal. The hidden color...

Embodiment 3

[0029] Anti-counterfeiting method for corporate invoice seals: This embodiment can also be realized by the method described in Embodiment 1 or 2 above. Here, enterprise-related information can also be bound in IC cards or other media, and dynamic passwords can be obtained by using mobile phones, telephones, networks or other communication methods. The enterprise uses the invoice stamp to form the invoice number, amount, etc. into a text message or other information form, and send it to the special number of the public network or the private network server of the specialized agency. After the server performs calculations, it returns a unique dynamic password containing the clock and information. Reflect this password on the invoice.

[0030] Passwords can be numbers, letters, symbols or a combination of them. The code can be reflected on the invoice by means of a separate wheel stamp or a special stamp with a wheel stamp. The dynamic password imprint can be reflected on the i...

Abstract

The invention discloses an anti-fake method for each kind of print. The technology scheme is: it uses optical, hologram technology and invisible imaging technology, plate making technology in photo taking process, uses the compression, encoding technology and computer OCR identification technology. The encoding technology adds a dynamic code which can be changed with the information and time on the print, the invention changes the static anti-fake code into dynamic code, the anti-fake object has the unique anti-fake code, and it can electrified, and managed on network.
