Abstract
The invention discloses a double-side seal database and a data generation method, which form a double-side seal holographic stamp laminated graph generation method by accurately superposing a main seal stamp graph and a secondary seal stamp graph, form the double-side seal database containing the double-side seal holographic stamp laminated graph, solve the problem of information defect existing on a manually obtained double-side seal laminated graph, ensure that whether the double-side seal laminated graph needing to be authenticated is complete or not, can accurately compare and authenticate, and provide favorable conditions for the smooth anti-counterfeiting work of a seal.
Description
Technical Field
The invention relates to a database and a data generation method, in particular to a double-side seal database and a data generation method (patent number of double-side seals: ZL 2018 0837321.0).
Background
The anti-fake function of double-side seal is to compare the identical between the stamp pattern of the double-side seal to be authenticated and the original and corresponding stamp pattern of the same kind in the database, especially the laminated stamp pattern of the double-side seal, to verify the truth of the double-side seal. However, the double-sided stamp is manually operated, and is affected by factors such as the uniformity of stamp ink on the stamp surface, the stamping force, and the paper quality (paper hardness and ink absorption capacity), and particularly, the raised print on the main stamp is unevenly distributed, so that a large range of blanks are formed on the main stamp surface.
However, being a defective secondary seal stamp is beneficial to prevent counterfeiters from forging the seal, because it is difficult for counterfeiters to obtain a complete secondary seal stamp pattern, and thus to counterfeit a double-sided seal identical to a true seal.
Disclosure of Invention
In order to overcome the defect that the double-sided stamp database lacks a complete double-sided stamp laminated graph, the invention provides a method for generating a double-sided stamp holographic stamp laminated graph, and the method is used for establishing a database containing the double-sided stamp holographic stamp laminated graph as original data for authenticating the double-sided stamp.
The technical scheme adopted by the invention for solving the technical problems is as follows: acquiring and recording a main seal impression diagram, a secondary seal impression diagram and a double-side seal impression stack diagram; determining 2 or more than 2 corresponding coincident points on the double-sided stamp laminating diagram; determining the corresponding coincident point positions on the main seal impression diagram and the auxiliary seal impression diagram respectively; and superposing the main seal stamp pattern and the secondary seal stamp pattern back to back into a composite pattern according to one-to-one correspondence of corresponding superposed points to form a double-sided seal holographic stamp laminated pattern, and storing the double-sided seal holographic stamp laminated pattern in a database so that the database contains the double-sided seal holographic stamp laminated pattern.
The method has the advantages that the method for generating the double-sided seal holographic stamp laminated graph is formed by accurately superposing the main seal stamp graph and the auxiliary seal stamp graph, the double-sided seal database containing the double-sided seal holographic stamp laminated graph is formed, the problem of information defect existing in the double-sided seal laminated graph obtained manually is solved, whether the double-sided seal laminated graph needing to be authenticated is complete or not can be accurately compared and authenticated, and favorable conditions are provided for smooth anti-counterfeiting work of the seal.
Drawings
The invention is further illustrated by the following examples in conjunction with the drawings.
FIG. 1 is a main stamp impression;
FIG. 2 is a view of a secondary seal stamp;
FIG. 3 is a double-sided stamp stack view;

fig. 5 is a structure view of a double-sided stamp.
In the figure, 1, an upper support, 2, a main stamp, 3, an auxiliary stamp, 4, a lower support and 5, a main stamp pressing rod are arranged.
Detailed Description
Example 1
Taking two sheets of paper, placing a backing plate between the two sheets of paper, wherein the backing plate plays the role of a traditional seal backing plate, placing the two sheets of paper together at an opening of a double-sided seal shown in figure 5, pressing down a main seal pressing rod 5 to enable the main seal 2 to descend, pressing down the main seal 2 and a secondary seal 3 to simultaneously stamp a main seal impression diagram 1 and a secondary seal impression diagram 2 on the two sheets of paper, lifting up the main seal pressing rod 5, taking out the two sheets of paper and the backing plate to obtain the main seal impression diagram and the secondary seal impression diagram in one step, taking one sheet of paper, placing the sheet of paper at the opening of the double-sided seal shown in figure 5, pressing down the main seal pressing rod 5 without placing the backing plate to enable the main seal 2 to descend, pressing down the main seal 2 and the secondary seal 3 to simultaneously stamp double-sided seal stacking diagrams 3 on the front and back sides of the paper, recording the three sheets of paper into a computer in a mode of a scanner or a photograph and the like, and obtaining a clear image of the double-sided seal stacking diagram 3 by a light transmission method; then, taking 2 or more than 2 corresponding coincident point positions on the double-sided stamp stacking diagram 3 through a computer, wherein the coincident point positions are taken to be 1 to several pixels in proper size at the pixel level to ensure the precision; confirming the corresponding coincident point positions on the main seal stamp diagram 1 and the auxiliary seal stamp diagram 2 respectively; and (3) superposing the main seal stamp pattern 1 and the secondary seal stamp pattern 2 into a composite pattern by back-to-back one-to-one correspondence according to corresponding superposed points to form a double-sided seal holographic stamp laminated pattern 4, and storing the double-sided seal holographic stamp laminated pattern 4 into a double-sided seal database.
Example 2
Firstly, taking a piece of paper, placing a backing plate above the paper, wherein the backing plate plays the role of a traditional seal backing plate, placing the two pieces of paper together at an opening of a double-sided seal shown in figure 5, pressing down a main seal pressing rod 5 to enable the main seal 2 to descend, pressing down the main seal 2 and a secondary seal 3 to stamp a secondary seal impression figure 2 on the paper, lifting up the main seal pressing rod 5, taking out the paper and the backing plate, taking a piece of paper again, placing a backing plate below the paper, placing the two pieces of paper together at the opening of the double-sided seal shown in figure 5, pressing down the main seal pressing rod 5 to enable the main seal 2 to descend, pressing down the main seal 2 and the secondary seal 3 to stamp a main seal impression figure 1 on the paper, lifting up the main seal pressing rod 5, taking out the paper and the backing plate, taking a piece of paper again, placing the backing plate without placing the backing plate, placing the backing plate on the double-sided seal 2 shown in figure 5, pressing down to enable the main seal 2 to descend, pressing down until the main seal 2 and the secondary seal 3 and the double-sided seal impression figure 3 are simultaneously, and recording a clear image of the double-sided seal by a scanner or a double-sided seal by a double-sided seal scanner; then, taking 2 or more than 2 corresponding coincident point positions on the double-sided stamp stacking diagram 3 through a computer, wherein the coincident point positions are taken to be 1 to several pixels in proper size at the pixel level to ensure the precision; confirming the corresponding coincident point positions on the main seal stamp diagram 1 and the auxiliary seal stamp diagram 2 respectively; and (3) superposing the main seal stamp pattern 1 and the secondary seal stamp pattern 2 into a composite pattern by back-to-back one-to-one correspondence according to corresponding superposed points to form a double-sided seal holographic stamp laminated pattern 4, and storing the double-sided seal holographic stamp laminated pattern 4 into a double-sided seal database.
