I’m in possession of two original pages that carry my handwritten signature, as well as two counterpart pages that appear to have been tampered with. I need a qualified document-forensics professional to determine whether any digital alteration has been made to the signatures on those suspect pages. I do need a formal courtroom report. Scope • Focus strictly on digital alteration detection; I am not looking for a full handwriting comparison or ink chemistry work. • The originals and the questioned pages are physical documents. Once we agree on the engagement, I’ll courier them (or high-resolution scans if you prefer that as a first step). • All I need back is a clear yes/no confirmation on whether the signatures have been digitally manipulated, along with a short explanatory note—no formal courtroom report is required. Your background If you regularly use tools such as VSC, UV/IR imaging, or high-magnification inspection stations for signature authentication, that’s exactly the expertise I’m after. A quick outline of your experience with similar cases will speed up my decision. Deliverable A concise written confirmation stating whether each of the two questioned pages shows evidence of digital alteration, supported by a brief description of the observed indicators. Turnaround Ideally within one week of receiving the documents, but let me know if your lab schedule requires more time. Let’s clarify any logistical questions up front so we can get this moving. Target deadline: April 7, 2026

Hi There! I have hands-on experience in digital document forensics and signature integrity analysis, including identifying signs of manipulation in scanned or reproduced documents. I’ve worked on similar cases where the goal was to determine whether signatures were digitally altered, overlaid, or artificially inserted, using high-resolution analysis, layer artifact detection, compression inconsistencies, and pixel-level inspection techniques. For your case, I can analyze either high-resolution scans (initial review) or physical documents if required, focusing strictly on digital alteration indicators—such as inconsistent pixel structure, cloning patterns, edge artifacts, or mismatched compression layers. You’ll receive a clear yes/no determination for each questioned page, along with a concise explanation of the findings. Turnaround can be completed within your requested timeline. Best Regards, Roman S.

Hello, I’m Shofiur Rahman, Digital Forensics specialist and Certified Ethical Hacker, with experience in document integrity analysis and digital alteration detection. For your case, I will focus strictly on identifying signs of digital manipulation in the questioned signatures, without extending into handwriting or ink analysis. My approach includes: - High-resolution image analysis (pixel structure, compression artifacts, edge inconsistencies) - Detection of copy-paste traces, layering anomalies, or resampling artifacts - Metadata and scan consistency review (if digital copies are provided) - Comparative analysis between original and questioned documents If physical copies are provided, I can also guide on high-magnification and imaging checks to identify digital tampering indicators. Deliverable: - Clear yes/no determination for each questioned page - Brief explanation of observed indicators supporting the conclusion Turnaround: 3–5 days after receiving documents (within your April 7 deadline) To proceed efficiently, I recommend starting with high-resolution scans (600–1200 DPI), followed by physical review if needed. Best regards, Shofiur Rahman CEO — Pentest Testing Corp
