Digital Image Watermarking use matlab(DWT,DCT), GUI use python

Due to increase in growth of internet users of networks are increasing rapidly. Owners of the digital products are concerned about illegal copying of their products. Security and copyright protection are becoming important issues in multimedia applications and services. Digital watermarking is a technology used for copyright protection of digita…

In this project, a simple watermarking system for spread spectrum audio is developed using the FFT transformation to insert the data into the signal host. The system is designed to resist the problem of desynchronization using synchronization codes.

A technique for embedding one mark or image within another using Entropy as a discriminant to identify the most strategic points of the image, DCT and DWT transforms are also used for insertion, the method is designed to be robust against jpeg compressions.

Matlab project on blind digital watermarking and encryption

The following final project thesis is the set of applications for an audio recognition and second screen system via digital audio fingerprinting and watermarking techniques.

This project is written by MATLAB R2020b for speech watermarking suitable for content authentication. Firstly, 4 folders are made by names of "original", "watermark", "extract" and "attack". Then 4 wav files are copied to "original" folder. Finally "final_1.m" can be run.
