Encrypt images through Homomorphic cryptosystem to ensure that third parties cannot know what the original data is even if they are authorized to process the image

An excutable program after compiling the cpp file can encrypt and decrypt image(.png, .jpg) using Paillier cryptosystem.

This program can only run on Linux operating system. You must install some required library to make sure the program run properly:

• Gmp library (https://gmplib.org/)
• libhcs (https://github.com/tiehuis/libhcs)
• opencv4 (https://github.com/opencv/opencv)

If you have already installed all required libraries, you can build the program with command below:

  g++ filename.cpp `pkg-config --libs opencv4` -o filename -lhcs -lgmp -std=c++11 -pthread

This is a university cryptography project for which we consulted a number of sources. We successfully tested it, but we are not responsible for any bugs.

This program is developed according to the idea presented in the attached .pdf report file. You can view it if you want. The report file is written in Vietnamese.
