Detailed Description
In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.
Example 1
As shown in fig. 1 and 3, the present embodiment provides a block chain-based human-computer interaction printing method, including the following steps: s1, in response to the uplink request instruction, uploading the original document to a block chain evidence storage platform and generating a document identification code and a decryption password corresponding to the original document; s2, associating and matching the printing sites; and S3, responding to the printing operation instruction, sending the target document identification code and the user-specific image to a printing station to print on a carrier, wherein the carrier can be paper, cups and other entities.
The original document in the step S1 may be a text, a picture or other document format, and the text may be in OFFICE software format such as WORD, PPT, EXCEL, PDF, etc. The editing and saving of the original document can be performed on an intelligent device provided with a blockchain client, the intelligent device is a mobile phone, a PC or a tablet computer and the like, and business system software and/or scanning recognition tools related to OFFICE software, WPS, Photoshop, CAD drawing, SolidWorks or format conversion software and the like can be installed on the intelligent device.
The editing and saving of the original document can be directly carried out on the intelligent equipment provided with the blockchain client, or can be sent to the intelligent equipment provided with the blockchain client based on a communication protocol after being edited and saved on another intelligent equipment, or can be carried out by directly carrying out the editing and saving of the original document on the embedded service application module of the blockchain client by arranging the embedded service application module in the blockchain client. For the former two, the blockchain client requires a document reading module to be provided to scan and obtain the original document locally on the smart device on which the blockchain client is installed. The embedded service application module refers to service applications built in the blockchain client, such as WORD, EXCEL, and the like.
The block chain client side is in communication connection with the cloud server, and the cloud server is also in communication connection with the block chain evidence storage platform, so that the original document edited or stored on the intelligent device can be uploaded to the block chain evidence storage platform through the block chain client side. The block chain client is provided with a login registration module for identity management, a local storage module for storing files, an uplink request module for requesting to upload an original document to a block chain evidence storing platform, a printing control module for sending a printing instruction to the block chain evidence storing platform, and a receiving and sending module for receiving and sending data or instructions to the cloud server and the block chain evidence storing platform. The login registration module, the local storage module, the uplink request module and the printing control module are respectively in signal connection with the transceiver module, and a login button, a registration button, an uplink button and a printing button are respectively arranged on an interactive interface of the block chain client.
The block chain evidence storage platform comprises a site configuration module, a communication module, a block chain storage module, a document analysis uplink module, an identification code generation module, an encryption module and an exclusive graph generation module. The block chain storage and certification platform receives an original document uploaded by a chain uploading request module through a communication module, performs a series of operations on the original document through a document analysis chain uploading module to complete chain uploading, generates a document identification code (the document identification code can be a two-dimensional code, a three-dimensional code or a bar code) and an associated user corresponding to the original document through an identification code generation module, encrypts the document identification code through an encryption module to generate a decryption password corresponding to the original document and used for searching, generates a plurality of exclusive graphs corresponding to the user identity through an exclusive graph generation module, generates a site identification code of each printing site through a site configuration module, stores various data through a block chain storage module, and is in communication connection with a cloud server and a block chain client through the communication module.
The site configuration module generates a site identification code according to detailed information such as an IP (Internet protocol), a printer name and an MAC (media access control) address of a printing site, wherein the site identification code is a two-dimensional code, a three-dimensional code or a bar code, contains a current printing site identification code, a user terminal identification and a user guide URL (uniform resource locator), and can be displayed on a display screen of the printing site or pasted at any position of the printing site after being printed, so that a user can scan and match the site identification code by using a scanning identification tool.
The method for generating the exclusive graphics by the exclusive graphics generation module specifically comprises the following steps: i, storing small figures with different shapes and endowing each small figure with a string of independent short digital codes; II, combining the short digital codes into a plurality of long digital codes with multi-bit independent digital codes; III, screening and deleting long digital codes of repeated combinations; IV, combining the corresponding small graphs to form an independent and unique large graph according to the rule of each long digital code; and V, uploading each large graph to a block chain card storage platform for a user to purchase as a user exclusive graph, binding the user exclusive graph with the user identity for encryption, and indicating the user identity by an exclusive graph record on the block chain. The generated exclusive graph is used for indicating the identity of the user, is added into a document identification code page, is sent to a printing site along with the document identification code, and is printed together with the document identification code.
In the step i, the blockchain evidence storing platform firstly asks designers to design a plurality of small figures with different shapes, inputs the blockchain evidence storing platform, then sets a string of independent short digital codes for each small figure through the blockchain evidence storing platform, generally a 4-bit string (for example, the small figure 1 corresponds to 0237), one short digital code corresponds to 1 small figure and corresponds to one without repetition, and then stores the small figure and the short digital code corresponding to the small figure.
In the above step ii, these independent short digital codes are combined into a long digital code with multi-bit independent digital codes according to a certain rule, generally a 48-bit string, by the block chaining verification platform.
In step iii, the blockchain evidence storing platform deletes the repeated long digital codes through the screening and deleting mechanism of the program, so as to ensure that the repeated long digital codes are not repeated. The screening and deleting procedures are prior art and will not be described herein.
In the step iv, the block chain evidence storing platform calls the corresponding small graphs from the database according to the rule of the long number codes, and then combines them to form an independent and unique large graph, that is, the large graph integrates a plurality of small graphs in one graph.
In the step v, the user can register a member in the blockchain client and choose to purchase the exclusive graphics, and can purchase and reserve 1 to 3 exclusive graphics, but only one exclusive graphics can be used as the exclusive virtual identification on the network each time. In addition, the exclusive graphics can also be randomly generated by the block chain evidence storage platform and sent to be displayed to the user. And after the exclusive graph is determined to be selected, the block chaining card storage platform carries out binding encryption processing on the exclusive graph and the user identity, the exclusive graph is not selected any more, and the unique relevance of the exclusive graph is guaranteed.
The step S1 is to generate a document identification code and send a decryption password corresponding to the document identification code, and the document contents can be referred to by scanning the document identification code and inputting the decryption password. The document analysis uplink module prompts a user whether to display document content in the uplink process, and if the user selects not to display the document content, other users cannot look up the document content uploaded by the user even if the user has an encryption password; if the document content is selected to be displayed, the decryption password is informed to other users, so that the other users can conveniently scan the document identification code by using the terminal equipment to look up the document content.
The association matching print station of step S2 specifically includes: s21, responding to the scanning operation of the site identification code attached to the printing site, identifying, correlating, matching and logging in the block chain client; s22, uploading the information of the printing station and the user information to a block chain evidence storing platform; and S23, associating the matching operation user with the printing site. The scanning operation in step S21 is to scan and identify the user by using a scan identification tool of the smart device, and guide the user to enter the blockchain client. Such as: when a browser is used for code scanning, automatically skipping to an APP downloading link of a corresponding platform according to an intelligent terminal platform (iOS or Android) used by a user, and guiding the user to download an APP; scanning codes by using the WeChat, automatically jumping to a WeChat small program providing cloud printing service when a user does not pay attention to the WeChat small program number of the cloud printing service, scanning codes by using a code scanning text in the WeChat small program, and directly entering a cloud printing function interface; and the user uses the APP to scan the codes, namely, the user directly enters the printing interface.
The smart device used in step S2 may be the same as or different from the smart device used in step S1.
Step S3 specifically includes: s31, responding to the printing operation instruction and sending out a printing instruction; s32, after receiving the printing instruction, sending the document identification code and the user exclusive graph to the associated printing site; and S33, the printing site receives the document identification code and the user-specific graph and starts printing. The user-specific graph is a user-specific graph B of a printing user, and the user-specific graph B is convenient for distinguishing a document identification code printer and can protect the privacy of the user. Of course, in some examples, the user-specific graphics in step S32 are the user-specific graphic B of the printing user and the user-specific graphic a of the uplink user, and only one user-specific graphic corresponding to the printing user and the uplink user is sent if the users are the same user. In some examples, the user-specific graphic in step S32 may also be the user-specific graphic a of the uplink user.
The method for controlling the print instruction in step S31 specifically includes: a1, designing and updating a printing contract; a2, judging the performance ability of the user to the target document according to the printing contract; and A3, feeding back a fulfillment result and controlling whether to send a printing instruction or not. Preferably, the print contract in step a1 includes calculation means of the fee, payment rules, rights, and the like; the step a2 specifically includes: a21, responding to the printing operation (namely clicking a printing button of a block chain client), and calling a cost accounting operator module to perform printing cost accounting on the target document according to the printing contract; a22, calling a balance check sub-module to check the balance on the user payment platform; a23, comparing the printing fee with the balance, entering a payment program if the balance is sufficient, and giving a prompt if the balance is insufficient. The step a3 specifically includes: a31, calling a payment submodule to enter a payment program according to a print contract; a32, calling a fulfillment feedback sub-module to feed back a payment result, and locking a printing function if the payment is unsuccessful; and A33, calling a printing switch submodule to control whether a printing instruction is sent or not according to the payment result.
Step S32 is to pack the corresponding document identifier and the user-specific graphic after the block chain storage platform receives the print instruction, and then send the document identifier and the user-specific graphic to the print site through the cloud server. And the printing site is provided with a block chain interface for receiving the document identification code and the user special graph and sending printing site information.
The embodiment also provides a human-computer interaction printing system based on the block chain, which comprises a terminal device, a printing station, a cloud server and a block chain evidence storage platform, wherein the printing station is in communication connection with the cloud server and is provided with a station identification code, the terminal device is in communication connection with the block chain evidence storage platform and is provided with an application program for accessing the block chain evidence storage platform and a scanning tool for scanning the station identification code, and the cloud server is in two-way communication with the block chain evidence storage platform.
