Problems solved by technology

[0003] There are the following problems in the management of printing documents in the enterprise: if there is no supervision on printing in the enterprise, and the employees do not have good printing habits, the employees will print at will, causing a lot of waste and high cost
However, when a company's confidential documents are leaked, the current printing management software cannot confirm that the confidential documents were leaked from the company
Another example is that after the document is replaced or forged, the current printing management software cannot solve it. Even if there is a record, other than the internal personnel of the enterprise are unwilling to believe it, because the enterprise database can be changed at will.

Embodiment 1

[0026] A method for implementing a blockchain-based printer according to the present invention includes:

[0027] S110. Receive the print file sent by the client, and embed the information of the print file into the block chain.

[0028] For example figure 1 As shown, the printers include shared printers, print servers, storage servers, and clients. There can be one or more shared printers, print servers, and storage servers, and generally multiple clients. The client is connected to the print server, and the print server is connected to the shared printer and the storage server respectively.

[0029] The information of the printed file includes the printed server, printer, user, client, number of printed bytes, number of printed pages, printing time, paper size, color, document name, document type, document content, etc. The information of the printed file also includes a hash value of the document content, that is, a hash operation is performed on the content of the print...

Embodiment 2

[0037] A method for implementing a blockchain-based printer according to the present invention includes:

[0038] S210. Receive the print file sent by the client, and embed the information of the print file into the block chain.

[0039] For example figure 2 As shown, the printers include network printers, storage servers, and clients. There may be multiple network printers, storage servers, and clients respectively. The clients are respectively connected to the storage server and the printer.

[0040] The information of the printed file includes the printed printer, user, client, number of printed bytes, number of printed pages, printing time, paper size, color, file name, file type, file content, etc. The information of the printed file also includes a hash value of the document content, that is, a hash operation is performed on the content of the printed document, such as a SHA256 hash operation. The information of the printed file embedded in the blockchain is selecte...

Embodiment 3

[0049] Propose a kind of printer according to the present invention, except the printer of prior art, also comprise print file information recording module, block chain client module, block chain client module includes block chain IPC interface; Described print file The information recording module is used to collect the information of the printed file, and send the information of the printed file to the block chain client module. The information of the printed file includes the printed server, printer, user, client, number of printed bytes, number of printed pages, printing time, paper size, color, document name, document type, document content, etc. The information of the printed file also includes a hash value of the document content, that is, a hash operation is performed on the content of the printed document, such as a SHA256 hash operation. The information of the printed file embedded in the blockchain is selected by the user according to the needs, such as: the number ...

Abstract

The invention belongs to the technical field of block chains and proposes a realization method for a block chain based printer. The method comprises the steps of receiving a sent printing file and embedding information of the printing file into a block chain. The block chain based printer comprises a printing file information recording module and a block chain client module, wherein the block chain client module comprises a block chain IPC interface; the printing file information recording module is used for collecting the information of the printing file and sending the information of the printing file to the block chain client module; and the block chain client module is used for embedding the information of the printing file into the block chain through the block chain IPC interface. With the adoption of the block chain based printer and the realization method, a printing management mode in an enterprise is established, and the leakage of enterprise internal confidential information and the falsification and replacement of the file are confirmed, so that the enterprise loss is made up for.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based printer and an implementation method. Background technique [0002] Blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data. Information cannot be forged and tampered with. Smart contracts can be automatically executed without any audit by a centralized organization. [0003] There are the following problems in the management of printing documents in enterprises: if there is no supervision on enterprise printing, and employees do not have good printing habits, employees will print at will, resulting in large waste and high cost. There are no specific statistics on the printing costs of various departments and employees. It is not known exactly what the staff printed. The printed paper was not claimed and it is not known who printed it. The documents you print out will be seen by others. Comp...
