Abstract

The invention discloses a multi-receiving-unit sending mechanism in a paper document sending information hiding system in the technical field of secret-related office, which comprises the following steps: receiving a new work request initiated by a user, the request comprising sending file information, sending unit information, information of a plurality of receiving units and the like; traversing and receiving the unit information list through a forEach function; obtaining first receiving unit information in sequence; using the receiving unit information to construct unique watermark information; transmitting 64-bit watermark information through a steganography tool interface, completing watermark write-in generation of a sent file, and then entering the next cycle until traversal is completely completed, and ending a new work task. According to the invention, in a scene that a user issues secret-related or non-secret-related files to a plurality of receiving units, not only are anti-leakage and tracing measures taken, but also the receiving unit information on the secret-leaked file can be quickly positioned when a file leakage event occurs, so that the tracing efficiency is improved.

Description

technical field [0001] The invention relates to the field of secret-related office technology, in particular to a multi-receiving unit sending mechanism in a paper document sending information hiding system. Background technique [0002] Since the formation of electronic documents, the security of electronic documents has been concerned by the majority of users. In the event of leakage of printed paper documents, the leakage is often not directly caused by the loss of the document, but more often through photography, video, copying, etc. The leakage of non-paper documents is often better concealed and difficult to find , and the difficulty of tracing the source is also very large. [0003] Aiming at the existing hidden dangers of electronic document printing, the invention provides a mechanism for sending and processing multi-receiving units in a paper file system. Embed invisible identification information in electronic document data by using special watermarking technolo...
