What is Robust Watermarking Against Print-Scan Attack about?
This document summarizes a research paper about developing a robust watermarking technique for PDF documents that can withstand print-scan attacks. The proposed method embeds watermarks by modifying edge pixels of text strokes in a way that changes can still be detected after a document is printed and scanned. The technique was found to have high invisibility, extract watermarks with 100% accuracy against attacks, and fully recover watermarks for unmodified documents. It could help trace leaks of official p
