Document Fraud Detection
Document fraud detection API for automated tampering and forgery detection. Metadata inspection, pixel analysis, font consistency checks.
What we detect
Metadata Analysis
Check PDF creation and modification dates, software used, author information. Detect documents created recently but claiming old dates.
Pixel Manipulation
Detect copy-paste regions, cloning, and image manipulation. ELA (Error Level Analysis) to find edited areas.
Font Consistency
Analyze font types, sizes, and spacing across the document. Flag inconsistencies that indicate text replacement.
Layout Analysis
Check alignment, spacing, and formatting against known templates. Detect irregular layouts suggesting modification.
Digital Signatures
Verify digital signatures and certificates. Detect broken or invalid signatures indicating post-signing changes.
Content Verification
Cross-check amounts, dates, and names for logical consistency. Detect impossible combinations or round numbers.
Detection Methods
Multiple analysis techniques combined for comprehensive fraud detection.
Structural Analysis
PDF structure inspection, layer analysis, hidden content detection. Find objects that shouldn't be there.
Visual Inspection
AI-powered visual analysis comparing against known document templates. Spot anomalies humans might miss.
Text Analysis
OCR confidence scoring, character-level anomaly detection. Find text that was added or modified.
Risk Scoring
Combined risk score from all analysis methods. Clear breakdown of what triggered each flag.
Supported Document Types
Fraud detection for all common document types.
Industry Use Cases
