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.
Allows invisible watermarking of text and invisible encrypted messages. Uses 17 different invisible characters as HEX + delimiter. Includes encoder, decoder, spammer and other tools.
python_wavelet_digital_watermarking
A rust implementation of spread spectrum watermarking for images.
This repository was created as an implementation approach for a project on "Watermarking Deep Neural Networks".
A Matlab project uses Signal Processing Technique — Digital Watermark to hide data in an audio track
🎓 Comparison of different digital image watermarking methods - DCT, DWT, SVD together with hybrids
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.
Robustness of DWT vs DCT is graded based on the quality of extracted watermark. The measure used is the Correlation coefficient (0-100%).
Resilient watermarking of digital images
This project uses a semi-blind watermarking approach to prove ownership of the image.
This repository contains an implementation of the 3D watermarking algorithm proposed by Cayre et al based on Spectral Decomposition.
