Hi Product Hunt! 👋
I built ID Watermark to solve a personal headache: sharing ID photos and documents online without worrying about unauthorized misuse or leaks.
Standard visible watermarks can easily be cropped or erased. That's why ID Watermark uses DCT/SVD algorithms to embed invisible, password-protected cryptographic tags directly into pixels. Even if modified, the ownership data remains extractable.
Most importantly, it operates 100% offline. Zero cloud uploads, zero tracking.
Would love to hear your feedback!
