Embodiment 1

[0021] The two-dimensional encrypted seal of the present embodiment is as figure 1 As shown, it includes the printed text 4 engraved on the bottom of the seal, the printed emblem 2 and the printed frame 1, 3 is the seal code; the printed frame 1 is composed of two circles of spaced concave-convex structures, corresponding to the following specific two-dimensional matrix coded information:

[0022] The organization code of the unit using the seal is: 716299204

[0023] Seal production time: 20050907 (digitized on September 7, 2005)

[0024] The organization code of the seal making unit is: 13584884

[0025] The information itself is a decimal number with some confidentiality, so it is very convenient to encode.

[0026] Two-dimensional codes have much more information capacity than one-dimensional barcodes, such as figure 2 As shown, for example, it is divided into two rows and six columns to form a 2×6 matrix, in which the black part represents binary 1, and the white part...

Embodiment 2

[0030] The two-dimensional encrypted seal of the present embodiment is as figure 2 As shown, further on the basis of Embodiment 1, the printing frame 1 is realized by image encryption, that is, the corresponding specific two-dimensional matrix coding information that needs to be recorded is carried out with the "messy" dot matrix obtained through image encryption processing. And or operation, to confuse it with the real information data, form two circles of complex spaced concave-convex lattice structure, and complete the encryption process.

[0031] When identifying, through the image collection of the finished seal, the useful information in the printed frame is taken out separately, and after corresponding comparison, the decryption code is obtained to obtain the dot matrix information of the original data, and then the binary information code is obtained through the data redundancy check. The detailed information of the implanted frame can be obtained, and the authenticit...

Abstract

The invention relates to an improvement for encrypt seal. The seal includes the stamp on the bottom of the seal and seal frame. The improvement is the frame is formed by two cycle separated sagging structure that has special two dimension matrix coding information. The two dimension matrix coding includes the following information: the code of the seal using organization, the date making the seal, and the code of the seal manufacture organization. The matrix coding could be encrypted. The invention would avoid minting seal privately, and improve the good faith of government affairs and business affairs.

Description

technical field [0001] The invention relates to a structure of a seal, in particular to an improvement of an encrypted seal, and belongs to the technical field of seal anti-counterfeiting. Background technique [0002] As we all know, the seal is mainly composed of the printed text and the printed frame on the bottom, and is an important right and identity certificate. Privately engraving seals, forging valuable documents and tickets are common methods used by criminals to carry out illegal and criminal activities. In recent years, the problem of seal management has become more and more serious, and illegal and criminal activities of counterfeiting seals have occurred from time to time, which shows that the traditional seal use and seal identification methods have not kept pace with the development of the times. [0003] In order to change the backwardness of seal use and seal recognition, people have carried out beneficial exploration along the following two paths: [000...
