About The Project

How it works

This system uses advanced digital image processing techniques to embed an invisible watermark directly into the frequency domain of an image. Unlike visible logos, our method ensures the original image quality remains visually untouched.

Tamper Detection

The algorithm is designed to be highly sensitive to malicious alterations. When an image is checked in the "Detect" section, the system analyzes the integrity of the hidden data to determine if the image is authentic, mathematically manipulated, or geometrically attacked.
