Trust Agent: Detecting manipulations

Third issue: Two invoices from Kaltwerk with the same number. At first glance they appear identical, but in one case someone has covered the bank details at the bottom with a white box and written new information over it. The Trust Agent checks whether any changes have been made to a PDF. We mark the copy, select Trust, and start the integrity check. For the document type, we choose Invoice, so that PaperOffice additionally pays attention to typical patterns in invoices. With Premium, PaperOffice highlights the findings directly in the document and creates a Marked evidence PDF. The result: Review recommended, with three findings. The most significant one: In the text of the PDF, a bank account number is present, which is obscured in the visible document by a shape drawn later, and a different one is displayed there. Additionally, the invoice lists bank account numbers from various countries. The risk score also appears as an icon in the list. The review by PaperOffice covered four areas: hidden content that is overlooked during normal viewing, the technical structure of the PDF, a comparison between what is visible and what is stored in the document, and additional patterns for invoices using the invoice profile. For comparison, the original: no anomalies detected. The Trust Agent does not tell you who committed fraud, but it shows you where to look more closely before making a payment. Another example, this time with the profile Application and CV: This resume contains an instruction to AI systems in very bright and tiny font, practically invisible to humans. The Trust Agent detects it and flags the resume as suspicious.
