Abstract
The invention relates to the anti-counterfeiting printing technical field, in particular to a multi-encryption and anti-counterfeiting printing method for a two-dimensional code which is applicable to the two-dimensional code and has encryption requirements on the information of the two-dimensional code, and the multi-encryption and anti-counterfeiting printing method is carried out according to the following steps: (1) original data of the two-dimensional code to be encrypted is input to an encryption system; (2) the encryption system takes out one or a plurality of bits from the original data of the two-dimensional code to carry out a first encryption algorithm calculation, thus obtaining a group of random check codes; (3) the group of random check codes are arranged in the original data of the two-dimensional code, thus generating a group of data containing the random check codes; (4) the obtained data containing the random check codes is carried out a second encryption algorithm calculation, thus generating the dual-encryption data; (5) the obtained dual-encryption data is utilized for generating the dual-encryption two-dimensional code; (6) the dual-encryption two-dimensional code is transmitted to a digital printing system for printing. The method can effectively prevent others from utilizing the existing two-dimensional code reading device to decode the encrypted content, thus obtaining the information in the two-dimensional code and having good confidentiality.
Description
Technical field
The present invention relates to the anti-counterfeiting printing technology field, particularly a kind of two-dimensional code multi-enciphering anti-fake printing method, this technology is applicable to the occasion that the two-dimension code internal information is had security requirements.
Background technology
In the prior art, the two-dimension code internal information just can be distinguished two-dimension code as long as the fake producer has corresponding two-dimentional recognizing apparatus, thereby obtain the two-dimension code internal information not through encryption.Like this, two-dimension code just can't be used under some have the occasion of security requirements.
Summary of the invention
The object of the present invention is to provide a kind of two-dimensional code multi-enciphering anti-fake printing method, this method can prevent effectively that other people from utilizing existing two-dimensional code reading equipment that encrypted content is deciphered to obtain two-dimension code internal information, good confidentiality.
The technical solution used in the present invention is: this two-dimensional code multi-enciphering anti-fake printing method, carry out as follows:
(1), with two-dimension code raw data input encryption system to be encrypted;
(2), encryption system takes out a certain position or several and carries out a re-encryption algorithm computing from this two-dimension code raw data, obtain one group of check code at random;
(3), with this group stochastic kernel to piling up in the two-dimension code raw data, generate one group and contain the data of check code at random;
(4), the data of check code that contain at random that obtain are carried out double cryptographic algorithm computing, generate the double-encryption data;
(5), utilize the double-encryption data that obtain to generate the double-encryption two-dimension code;
(6), the double-encryption two-dimension code is transferred to digital printing system printing.
The decryption method of this two-dimensional code multi-enciphering anti-fake printing method, carry out as follows:
(1), utilize the recognizing apparatus contain decrypted program to read the double-encryption two-dimension code, obtain the double-encryption data;
(2), the double-encryption data are carried out double decipherment algorithm computing, obtain containing the data of check code at random; As do not obtain containing the data of check code at random, promptly be accredited as vacation;
(3) carry out a heavy decipherment algorithm computing, the two-dimension code raw data that obtains deciphering to containing at random the data of check code; As the two-dimension code raw data that does not obtain deciphering, promptly be accredited as vacation.
Distinguishing feature of the present invention is to carry out multi-enciphering according to the raw data that the user improves, generating the double-encryption two-dimension code prints, the terminal user holds the recognizing apparatus that contains decrypted program and reads data in the double-encryption two-dimension code, this technology is applied to the two-dimension code internal information is had the product of security requirements, the fake producer has the problem that two dimension code reading equipment just can obtain the two-dimension code internal information as long as can effectively solve in the past, thereby has improved confidentiality greatly.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
