Anti-leak method and anti-leak module based on noise

Abstract

The noise-based anti-leakage method and the anti-leakage module involve information anti-leakage technology, and the purpose is to solve the problem that watermarks and QR codes are easy to be stolen, and once leaked, the leakage path cannot be judged. The present invention first receives the original electronic version of the print file, and records the IP address of the computer that sent the original electronic version of the print file and the time of receiving the file, randomly generates a noise image matrix of a corresponding size according to the size of the paper, and then stores the noise image matrix and sends the original The computer IP address of the electronic version of the printed file and the time of receiving the original electronic version of the printed file, and the noise image matrix is ​​loaded onto the original electronic version of the printed file to form a leak-proof electronic version of the file, and finally the file is sent to the printer for printing. The noise image of the present invention is not easy to be stolen, and once leaked, it is also easy to trace the leaking route, which greatly reduces the hidden danger of enterprise confidential information, and is applicable to various enterprises involving confidential information.

Description

technical field [0001] The invention relates to information leakage prevention technology. Background technique [0002] A common anti-disclosure (or anti-theft, or anti-counterfeiting) method is to add watermarks on confidential documents, but watermarks are usually relatively simple patterns, which can be easily extracted and removed by image processing tools. In recent years, with the development of two-dimensional code technology, many confidential documents have added two-dimensional codes to replace watermarks. Using two-dimensional code scanning technology can easily extract two-dimensional code images, and two-dimensional codes are located in the file Blank space, covers very little area and is easy to remove. Therefore, whether it is a watermark or a QR code, it is easy to be stolen. Once it is stolen and printed on other documents, it is impossible to tell whether the document is a confidential document. For leaked confidential documents, it is also impossible to ...
