PDFs. Down to the last glyph.

Bank statements, invoices, payslips and digital certificates — inspected at the file-structure level, where most edits leave a trace.

03Content & identity

What it says, and whether it adds up.

Beyond the file itself — the numbers, the names and the identities are checked against each other and against the source.

Kriyam TamperFlow. The benchmark behind the pipeline.

An open benchmark for document tampering detection under realistic processing pipelines — printing, scanning, photocopying and digital sharing. Models that look strong on pristine datasets often fail here; DocForensics v2 is built for exactly these conditions.

1,050 human-annotated authentic and tampered document images
5 state-of-the-art models evaluated — the best reaches a Region-F1 of only 0.10
Frequency-domain methods lose up to 68.7% of localization under photocopy
Kriyam TamperFlow: Benchmarking Document Tampering Detection under Realistic Document Processing Pipelines Avishek Jana¹ · Swati Kumari¹¹ Kriyam.ai Labs, GEOGO, India Abstract As Document AI systems increasingly automate document processing at scale across high-stakes industries, ensuring the integrity of every processed document is no longer feasible through human review alone. Even a single tampered field within a document can facilitate fraud, identity theft, or record manipulation before it is detected. In this paper, we introduce Kriyam TamperFlow, an open benchmark for evaluating document tampering detection under realistic document processing pipelines… zenodo.org/records/21972485Read paper →
