Why ID Sentinel?

When you're asked to provide a photo of your ID for verification purposes, you're placing your most sensitive personal information at risk. ID Sentinel helps you protect this data by applying advanced, persistent watermarks that make unauthorized reuse extremely difficult.

100% Client-Side

Your photos never leave your device. All image processing, watermarking, and steganography happens directly in your browser. We have zero servers processing your data.

Advanced Protection

Beyond standard visual text, we apply noise patterns, interwoven grids, and invisible LSB (Least Significant Bit) watermarks to resist AI-based removal attempts.
