OpenStego is a steganography application that provides two functionalities: a) Data Hiding: It can hide any data within an image file. b) Watermarking: Watermarking image files with an invisible signature. It can be used to detect unauthorized file copying.
Audio Watermarking
Official implementation of the paper "The Stable Signature Rooting Watermarks in Latent Diffusion Models"
AI-based Audio Watermarking Tool
The digital watermark for image and pdf.
python_wavelet_digital_watermarking
Allows invisible watermarking of text and invisible encrypted messages. Uses 17 different invisible characters as HEX + delimiter. Includes encoder, decoder, spammer and other tools.
This repository was created as an implementation approach for a project on "Watermarking Deep Neural Networks".
A rust implementation of spread spectrum watermarking for images.
A Matlab project uses Signal Processing Technique — Digital Watermark to hide data in an audio track
This is an implementation of embedding and extracting a digital watermark in a PDF document. The code uses an LDPC code, a Hadamard code, and multiple sequence alignment to increase robustness.
🎓 Comparison of different digital image watermarking methods - DCT, DWT, SVD together with hybrids
Robustness of DWT vs DCT is graded based on the quality of extracted watermark. The measure used is the Correlation coefficient (0-100%).
Demo of Digital Watermarking in images
This repository contains an implementation of the 3D watermarking algorithm proposed by Cayre et al based on Spectral Decomposition.
This project uses a semi-blind watermarking approach to prove ownership of the image.
Video Steganography / Watermarking Demo Tool
This code provides a solution for digital image authentication, tamper localization, and content recovery using fragile watermarking.
This code provides a solution for digital image authentication and tamper localization using reversible fragile watermarking.
