AI-powered document tampering detection that catches forged receipts, manipulated invoices, and synthetic documents in seconds.
Run TamperCheck where it fits your security and latency requirements.
Full-power detection via our hosted API. Best accuracy with our largest ensemble models. No infrastructure to manage.
Run detection locally using Qwen2.5-VL, Alibaba's open-weight vision-language model. Zero data leaves your environment. Ideal for air-gapped or privacy-sensitive deployments.
Watch how TamperCheck detects tampered images and deepfakes in seconds.
Detection accuracy depends on your document types, your fraud patterns, the image quality you capture, and which model is doing the work. As an honest reference point, the latest Gemini VLM scores around 77% on public deepfake and image-manipulation benchmarks.
We tune TamperCheck for your data and your deployment (cloud, customer VPC, or on-premise) and report measured accuracy on your own sample set during onboarding. No generic 99% claims.
Traditional verification methods can't keep up with sophisticated digital manipulation of scanned documents and receipt photos.
Employees modify receipt amounts, dates, and vendor names using basic editing tools.
AI tools generate completely fake but realistic-looking receipts in seconds.
Fraudsters duplicate and modify legitimate receipts for multiple claims.
Human reviewers miss subtle manipulations and can't scale to volume.
Our advanced neural networks analyse every document through multiple detection methods simultaneously.
Detects signs of digital tampering, copy-paste artifacts, and unnatural modifications at the pixel level.
Identifies AI-generated or synthetic documents using advanced neural networks trained on millions of samples.
Finds evidence of digital editing tools like cloning, healing brushes, and content-aware fills.
Analyses image metadata for inconsistencies including EXIF data, timestamps, and device fingerprints.
