An automatic identification method for secret drawings

Abstract

The invention discloses an automatic identification method for confidential drawings, which utilizes the characteristics of large amount of information, high security, and strong anti-interference performance of two-dimensional barcodes to compress and encrypt relevant information of confidential drawings and store them in two-dimensional barcodes, and placed on the drawing. When the drawing file is intercepted, the image processing technology is used to automatically detect the two-dimensional barcode in the drawing, and after identification and decoding, it is identified whether it is confidential content. Specifically, it includes steps such as the production of two-dimensional barcodes, the detection of two-dimensional barcodes, the binarization of two-dimensional barcodes, the rapid anti-perspective transformation, and the identification of confidential information. The method disclosed by the invention effectively solves the problem of automatic identification of secret-related drawings, and can quickly and reliably complete the identification of secret-related drawings.

Description

technical field [0001] The invention relates to an automatic identification method for confidential drawings, which belongs to the field of information security and automatic identification. Background technique [0002] In the information age, both military research institutions and civilian enterprises are maximizing the use of information technology to improve the efficiency of R&D and design. The design drawings of military or civilian products are regarded as core secrets and often exist in the form of electronic documents. [0003] In order to avoid unintentional or malicious disclosure of confidential information during network transmission and media exchange, software is often used to monitor network transmission and media exchange files. For example, a firewall is installed in the mail sending and receiving system to intercept the transmitted files for judgment. Among them, how to automatically identify whether the content in an image file is confidential is the k...

Problems solved by technology

If image analysis technology is used to automatically identify each element of the image file, and then compare it with the existing model to determine whether it is confidential, the technology is difficult and difficult to implement

Therefore, the identification and interception of text-based confidential information is very effective, such as Word documents, but it cannot solve the identification of confidential drawings based on image information.
