Robust Image Comparison (ZNCC/SSIM)

Advanced comparison using Zero-Normalized Cross Correlation and SSIM. Includes alignment search and anomaly detection.

Compare Ultra (PUF Analysis)

Specialized comparison focusing strictly on the PUF ROI (157,157 to 243,243).

API Documentation

Active endpoints for Photo Decoder, Compare Ultra, and Copyvoid.

Photo Decoder (Session)

• POST /internal/decode-photo - Multipart Form [email protected]
• POST /internal/decode-photo-base64 - Form image_base64=data:image/...;base64,...
• Response fields: success, decoded_text, normalized_png_base64, normalized_svg_base64, rotation_angle, marker_score, error

Compare Ultra (API Key)

• POST /api/compare-puf - JSON compare request (reference/candidate base64)
• Response includes ok, decision, metrics, alignment, roi, threshold_used, quality. Out-of-range captures return retry-style quality errors using the same readability gate as truth-mode training.
• Optional request fields active_device, truth_label, feedback_note, feedback_source let you store device-tagged labeled training examples inline. When truth_label is sent, the request runs in training-only mode and does not return a live authenticity verdict.

Copyvoid (API Key)

• POST /api/compare-puf with noise_style=copyvoid or header X-ASLI-Noise-Style: copyvoid
• Response includes comparison_mode, noise_profile, style_scores, and Copyvoid-specific headers.

Compare Ultra Logs (Session)

• GET /admin/compare-ultra-logs
• GET /admin/compare-ultra-logs/settings
• POST /admin/compare-ultra-logs/settings - { "enabled": true|false }
• POST /admin/compare-ultra-logs/reset (clears logs without export)
• GET /admin/compare-ultra-logs/export.csv (exports and clears logs)

Copyvoid Logs (Session)

• GET /admin/copyvoid-logs
• GET /admin/copyvoid-logs/settings
• POST /admin/copyvoid-logs/settings - { "enabled": true|false }
• POST /admin/copyvoid-logs/reset (clears logs without export)
• GET /admin/copyvoid-logs/export.csv (exports and clears logs)

Feedback Memory

• POST /api/compare-feedback - API key protected labeled feedback ingestion
• GET /admin/compare-feedback/summary
• POST /admin/compare-feedback - store Original / Counterfeit truth labels from dashboard logs
• POST /admin/compare-feedback/device-profile/delete - delete a device profile after password confirmation
• POST /admin/compare-feedback/export.csv - requires DeviceProfileAdmin password
• POST /admin/compare-feedback/reset - clears only non-device/global feedback rows
