Hello,
I'm Ali Ahmad, and I specialize in digital forensics, including analyzing PDF files for metadata, tampering, and system details. I can thoroughly investigate the PDF files you provide, focusing on the creation date, device/system ID, and verifying if any tampering has occurred.
For this project, I would use a combination of forensic tools and manual analysis to validate the structure of the files and deliver a detailed report on the findings. I would be happy to provide my rate per file and the tools I would use, which typically include forensic software like PDF X-Ray and other industry-standard tools.
Let me know if you would like to discuss this project in more detail!
Best regards,
Ali Ahmad
