Abstract

This paper proposes a design approach for an encryption tool based on image processing and PDF manipulation to meet the encryption requirements of sensitive design drawings. The tool is developed using Python programming language and the OpenCV-Python library. Designers can choose encryption fields through a GUI, including modifying product name, removing stage markers, and changing approval date, among others. Additionally, there are two encryption modes available for selection: combined into an one encrypted PDF or each PDF encrypted separately. Batch encryption of all PDF drawings within a selected path can be completed very quickly, significantly reducing the time and workload required for manually encrypting multiple PDF drawings. This greatly improves encryption efficiency and eliminates tedious repetitive work. The program avoids human errors and ensures that sensitive information remains protected from unauthorized access.
