Technical Field
The invention relates to the technical field of confidential office work, in particular to a multi-receiving-unit sending mechanism in a paper document sending information hiding system.
Background
Since the formation of electronic documents, the security of electronic documents has been receiving attention from a large number of users. In the event of leakage of printed paper documents, the leakage of the documents is often caused not by the loss of the documents directly, more often by the modes of photographing, video, copying and the like, the leakage of the non-paper documents is often more concealed and not easy to find, and the tracing difficulty is very high.
Aiming at the existing hidden danger of electronic document printing, the invention provides a mechanism for sending and processing multiple receiving units in a paper file system. Invisible identification information is embedded in electronic document data by using a special watermarking technology. The identification information still exists after the printing operation, can still be correctly extracted and identified after the operations of photographing, video, copying and the like, and can position the distribution source of the document, thereby carrying out the safety control and traceability of printing and information transfer on the target document. The processing mechanism of multiple receiving units can accurately position the same text file to the information of a certain receiving unit.
In the prior art, the method aims at the printing output of an electronic document, extracts contents and only records the related information of a user, does not record the information of a receiver and has limited application scenes; if a multi-receiving unit mechanism is not used, the tracing of the file can only be carried out to a sending unit, and the same file can not be accurately sent to a certain receiving unit.
At present, a paper document tracking method with a patent number of CN 111241364A discloses first acquiring identity information uploaded at a terminal, and if a user corresponding to the acquired corresponding identity information has a management authority of the paper document, generating a unique code for the paper document according to related information; determining a file circulation mode of the paper file; and according to the file circulation mode, the unique code is pasted on the paper file in a bar code or two-dimensional code mode, and the paper file is tracked by utilizing hardware equipment.
The method and the system for file information output leakage prevention and source tracing of the patent number CN 107423629A deploy a file information output operation monitoring service system at a file information output terminal; when the file information output terminal carries out file information output operation, the file information output operation monitoring service system automatically carries out information leakage prevention treatment in file information output contents, wherein the information leakage prevention treatment comprises adding invisible watermark information; and then converting the carrier content after the file information is output into image data in an electronic format, operating a watermark information extraction and identification program to detect the watermark information, and performing file information leakage tracing operation.
However, the above two technologies only track and trace the files on the single-machine terminal, and do not solve the problems that the files are issued and the multiple receiving units are issued in the scene.
Based on the above, the invention designs a multi-receiving unit sending mechanism in a paper document sending information hiding system, so as to solve the above problems.
