As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. In the following description, different "one embodiment" or "another embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The specific schemes of the method and the device for generating the artistic QR code, the electronic device and the storage medium provided by the invention are specifically described below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for generating an artistic QR code according to an embodiment of the present invention is shown, in order to solve the technical problem of tampering a two-dimensional code, the embodiment of the present invention prevents the two-dimensional code from being tampered by using a multi-node storage characteristic of a block chain, encrypts initial plaintext information before encoding the two-dimensional code data for reinforcement and defense measures, and combines block chain storage and encryption before encoding to achieve a hierarchical layer-by-layer defense to prevent the two-dimensional code data from being tampered. Specifically, the artistic QR code generation method comprises the following steps:
and S001, encrypting the two-dimensional code data to obtain encrypted two-dimensional code data.
The two-dimensional code data comprises text data and background image data, wherein the text data can be text information such as a website, an email address, a contact way or WIFI configuration.
And encrypting the two-dimensional code data by adopting a homomorphic encryption algorithm. Specifically, a public key and a private key used by an encryption function generated by KeyGen are adopted, and then an Encrypt function is utilized to perform homomorphic encryption on input website data to obtain encrypted data.
And S002, encoding the encrypted two-dimensional code data generated in the step 001 by using an art QR code generation algorithm to generate an encrypted art QR code.
It should be noted that the artistic QR code generation algorithm is a general generation algorithm, and the artistic QR code generation algorithm is not the invention of the present application, and the generation algorithm capable of generating the artistic QR code by encoding can be applied to this scheme, and the specific generation algorithm to be used is a routine choice performed by those skilled in the art as needed.
And step S003, storing the encrypted artistic QR code on the block chain.
And (4) storing the encrypted artistic QR code generated in the step 002 into the block chain by using a Hash algorithm.
Preferably, when the encrypted artistic QR code is stored in the block chain, a block identification code is first assigned to the encrypted artistic QR code, and then the encrypted artistic QR code is stored in a block corresponding to the block identification code. Wherein each block has a unique block ID as a block ID.
It should be noted that the encrypted artistic QR code is stored in the block chain through the non-intelligent contract, and flexible data storage can be realized by storing data through the non-intelligent contract, so that the two-dimensional code data can be prevented from being tampered to a certain extent.
And step S004, issuing the encrypted artistic QR code.
And releasing the encrypted artistic QR codes stored in the block chain to the outside so as to be identified by scanning codes by a user.
In summary, the embodiment of the present invention provides a method for generating an art QR code, where the method encrypts and encodes original two-dimensional code data to generate a corresponding encrypted art QR code, and stores and issues the encrypted art QR code on a block chain. Because the block chain has the encryption algorithm, and the block chain encryption algorithm is different from the encryption algorithm of the original two-dimensional code data, the tampering difficulty of the two-dimensional code is increased, and the artistic QR code is prevented from being tampered.
To further illustrate the scheme of the present invention, the official website of zheng zhou university is taken as an example below, and the official website of zheng zhou university is: www.zzu.edu.cn, taking the website data as original two-dimensional code data needing to be stored in the artistic QR code, and selecting an image as a background image of the artistic QR code according to the requirement, wherein the artistic QR code generating method comprises the following steps:
step 101, encrypting the website data to obtain encrypted two-dimensional code data, wherein the encrypted two-dimensional code data is shown in fig. 2.
And 102, encoding the encrypted two-dimensional code data generated in the step 101 by using an art QR code generation algorithm, and generating an encrypted art QR code by fusing a background image, wherein the encrypted art QR code is shown in figure 3.
Step 103, using the block chain storage technology to store the encrypted artistic QR code shown in fig. 3 into the corresponding block in the block chain. As a result, fig. 4 is a schematic diagram of a blockchain storage structure, which includes information such as a block data value, a previous block hash value, a block number, and a date.
And 104, issuing the encrypted artistic QR code.
In summary, according to the method for generating the artistic QR code provided by the above embodiment, in the generation process, a homomorphic encryption algorithm is adopted for data protection; the characteristics of block chain decentralization and distributed data storage are utilized to store the QR code data information on the block chain, and due to the fact that the block chain has a synchronization mechanism, the correctness of corresponding artistic QR codes stored by other nodes cannot be influenced even if the artistic QR code of a certain node is tampered, if the information of most nodes is correct, the information tampering is invalid, the purpose of self-checking and error correction is achieved, and the problem that the artistic QR code information is easily tampered is solved.
