Re-upload detection
for dating apps
Banned users re-register with the same photos. Catfishers recycle stolen profile images across fake accounts. On dating apps this is not a moderation problem — it is a physical safety problem.
← All use casesThe problem
- ✗Banned users create a new email, upload the same profile photos, and are back on the platform within minutes.
- ✗Catfishing attacks use stolen images that have already been processed and saved — they look different enough to bypass hash checks.
- ✗Small trust and safety teams cannot manually review every new profile photo against a growing blocklist.
- ✗A single missed re-registration can lead to offline harm — the stakes are far higher than typical content moderation.

How Rechase helps
Photo fingerprinting on signup
Every profile photo uploaded during registration is fingerprinted in real time. Matches against the banned-photo database block the account before it goes live — not after a complaint.
Catches cropped and filtered photos
Perceptual hashing survives the editing tricks bad actors use: face crops, Instagram filters, slight rotations, brightness adjustments. The same face is the same face.
Scales with a small T&S team
Automated blocking means your team reviews only the uncertain cases — matches below the confidence threshold — rather than manually checking every new signup against a growing blocklist.
Detection methods
What each layer catches specifically on dating apps.
| Method | What it catches on dating apps | Latency |
|---|---|---|
| SHA-256 | Unedited photo re-use — banned users who upload the exact same profile photo file | < 1ms |
| pHash | Cropped face shots, filtered photos, slight re-saves and compressions of the same original image | < 5ms |
| CLIP | Catfished photos borrowed from social media and re-processed, same person photographed from different angles | 30–50ms |
