Abstract
The invention relates to an anti-counterfeit method for a stamp. The method is characterized by comprising the following steps of: selecting or manufacturing a bearing medium (D), wherein the inside or the surface of the bearing medium (D) contains a randomly-distributed material (random material (A) for short); arranging a stamp (B), a positioning mark (C) and unique sequence information (E) on the bearing medium (D); acquiring an area which contains the stamp (B), the positioning mark (C) and the bearing medium (D) of the random material (A) and taking the area as an image; naming the image with a unique sequence and storing the image in a storage medium so as to obtain the bearing medium (D) (anti-counterfeit product for short) with anti-counterfeit function by stamping; and when the truth or falseness of an anti-counterfeit product needs to be identified, allowing a user to obtain the image named with the unique sequence and stored in the storage medium according to the unique sequence information printed by the bearing medium (D), comparing the distribution characteristic of the random material (A) in the image corresponding to the positioning mark with the distribution situation on a practical anti-counterfeit product to check accordance, determining the truth of the product if the distribution characteristic of the random material (A) in the image is accordant with the distribution situation on the practical anti-counterfeit product and determining the falseness of the product if the distribution characteristic of the random material (A) in the image is not accordant with the distribution situation on the practical anti-counterfeit product.
Description
Technical field:
The present invention relates to a kind of anti-counterfeit method for stamp, particularly a kind ofly utilize random material to combine to carry out false proof method with seal.
Background technology:
At China's seal impression is the sign of power and wealth, plays crucial effect.In recent years, domestic and international offender and clique were in order to usurp power, reap staggering profits, a swindle huge sum of money utilizes the seal trade management not tight, and seal is scribed backward in technique, lack chances such as effective false proof measure, forge law enforcement agencies such as administrations at different levels, customs, the tax, public security without restraint, financial institutions such as bank, insurance, and unit such as enterprises and institutions and legal person's seal impression, upset the public, cause serious economy loss for country, collective and individual.In order to take precautions against and hit the criminal activity of falsification of seal, adapt to the active demand of society, many companies, R﹠D institution and institution of higher learning have carried out the research and development of anti-counterfeit of seals technology and products thereof, and present stage, main anti-counterfeit of seals technology had chapter body picture and text to encrypt, improve seal to scribe level, anti-counterfeiting stamp ink and ink paste, the novel chapter body of application.But aforesaid way still exists by the imitated situation that may and can't add up information such as seal access times.
Summary of the invention
A kind of anti-counterfeit method for stamp, it is characterized in that: select or make a kind of bearing medium (D) for use, the material (being called for short random material (A)) of random distribution is contained in the bearing medium (D) or surface, on bearing medium (D), add and be stamped seal (B), telltale mark (C) and uniqueness serial number information (E), the zone that collection contains the bearing medium (D) of seal (B), telltale mark (C), random material (A) is an image, and image is named and is stored in the storage medium with the uniqueness sequence number; So just obtain by with an official seal affixed and the anti-fraud functional bearing medium (D) that has that obtain is called for short anti-fake product; When needs are differentiated the anti-fake product true and false, the uniqueness serial number information that the user prints according to bearing medium (D) obtains with the name of uniqueness sequence number and is stored in image in the storage medium, the distribution characteristics of the random material in this image (A) relative positioning mark is relatively seen whether conform to the distribution situation on the actual anti-fake product, if conform to then for true, otherwise be false.
