PDF Forensics Without the Original File: One-Sided Fraud Detection

1. 1Read the PDF file to extract structural signals
2. 2Analyze the extracted signals to identify potential tampering
3. 3Use the HTPBE algorithm to detect anomalies in the document's structure
4. 4Compare the results with known patterns of tampered PDFs
5. 5Validate the findings using additional forensic tools

This technique benefits cybersecurity teams and digital forensic analysts who need to verify the authenticity of PDF documents, especially when the original file is not available

💡 PDF documents preserve structural signals that can be used to detect tampering, even without the original file
