Forgery detection is the process of identifying tampered or altered images and documents. ImgAuth.com is a professional forgery detection tool powered by AI that detects image tampering and forgery in certificates, invoices, documents, and other image formats. Our forgery detection system uses deep neural networks and cross-modal analysis technology to identify various tampering methods including cut-and-paste, content replacement, local smudging, and forgery repair. The tool provides heatmap visualization to clearly mark tampered regions, making it perfect for financial risk control, government verification, insurance claims, and logistics risk management.
