SUPPORT INVESTIGATIONS THROUGH PDF FORENSICS
Detect Forged And Falsified PDF Documents
In the business world, PDF files are used for a number of different purposes. For instance, they act as proof for transactions, contracts or as a stand-in for documents on paper. But it is a widely-spread misconception that PDF files cannot be digitally altered and are therefore tamper-proof. It is possible to achieve more security by digitally signing documents, but this practice is only rarely used.

Detect Manipulated and Modified PDF Documents
In fact, there are many possibilities to alter a PDF file. For example, it is entirely possible to manipulate the analog original by cutting pieces out, gluing them together and scanning the product afterward. But of course, the PDFs can also be altered using an image editing software or free office software tools. Even the original software to create PDF files allows several ways of retroactively editing the files.
PDF Forensic: Identify Manipulated PDF Documents
Making sure a PDF file is real can be important in several areas.
For instance, the corma experts can examine invoice documents for insurance companies, or bills to detect cases of warranty fraud.
In another case a business partner of a mandator has submitted a phoney “BWA” PDF document (financial business analysis).
With the forensic investigation of the PDF file by corma it was determined that the file was composed of different images.
One can expect one image per scanned page but we found 4-5 images per page. This information plus evidence from the documents metadata made it very clear:
It was clearly not a correct scan of the original document. This document was manipulated. See the image with a snapshot from the investigation.
