The scan is always free. Unlock details and certification when it matters.

⚠️ The free scan detects exact matches. If someone cropped, flipped, compressed or screenshot your image — only Check Pro sees it. It runs 4 additional detection passes including DINOv2 semantic analysis.

Artists & Designers

Protect your work before you share it. Stop stolen concepts before they're claimed.

"I certified the brief before the pitch meeting."
🪙

NFT Creators

Check if an image was already minted. Or prove yours was first.

"Someone re-minted my work on OpenSea. SBIX found it in 4 seconds."
📰

Journalists & Fact-checkers

Is this image really from where they say? Verify before you publish.

"We verified the image was recycled from a 2019 story."

Not just image search. Forensic analysis.

Check Pro runs 4 detection passes that the free scan skips entirely.

Pass 01 — Free
Perceptual fingerprint search
pHash + dHash + aHash across 5M+ indexed images. Catches exact or near-exact copies instantly. VRC HNSW O(log N) — p99 161ms.
Pass 02 — Check Pro
Flip / rotation variants
7 geometric transforms tested. Catches mirrored, rotated and 90°-flipped versions that fool basic hash search.
Pass 03 — Check Pro
ORB + RANSAC geometric verifier
Keypoint matching with geometric consistency check. Catches screenshots, partial crops and watermark-removed versions.
Pass 04 — Check Pro
DINOv2 semantic analysis
Vision transformer embedding. Detects heavily cropped, grayscale-converted or stylistically modified versions. Only fires when passes 1–3 find no confirmed copy.

Three independent anchors. One proof.

Your certification is locked in three places simultaneously.

Who is SBIX for? ▾
Artists, photographers, NFT creators, journalists — anyone who publishes original visual work and needs to know if it was copied, or prove it came from them first.
What's the difference between "Matches found" and a confirmed copy? ▾
A match means the image exists in our index on a platform — it doesn't tell you who was first. If the match is from a creator platform like Teia or Objkt, SBIX shows "Origin disputed" because priority is unclear without a timestamp. Check Pro reveals the exact source URL and date. If you created this file, Certify records a cryptographic timestamp proving when your file existed — that timestamp is what matters in a dispute, not a claim of ownership.
What does "Similarity strength" mean? ▾
It's a 0–100 score indicating how visually strong the match signal is across the SBIX index — combining match count, similarity percentages, and source diversity. A high score means multiple strong visual signals. It is not a legal determination of authorship.
Is the free scan enough? ▾
The free scan detects exact and near-exact copies. If someone has cropped, flipped, compressed, converted to grayscale, or taken a screenshot of your image — the free scan may miss it. Check Pro runs 3 additional detection passes (flip variants, ORB+RANSAC, DINOv2 semantic analysis) that catch modified versions.
What does "qualified timestamp" mean? ▾
A qualified timestamp under RFC 3161 is issued by a trust service provider on the EU Trusted List. It creates a legal presumption of prior existence admissible in courts across EU member states. It's generated by a certified external authority — not our clock, not adjustable after the fact.
How many images are in the index? ▾
Around 5 million fingerprints indexed across 15+ platforms as of March 2026 — Teia, Objkt, fxhash, Rarible, Wikipedia, NASA, Met Museum, Smithsonian, Europeana, Rijksmuseum, DPLA, Internet Archive, CommonCrawl, and more. The index grows continuously.
Does SBIX keep my image? ▾
The scan processes your image to generate a SHA-256 cryptographic fingerprint and perceptual hashes. Your original file is never stored or retained. Only the visual signature is kept for search purposes.
