| Abstract: | In this project work, a cryptographic system is developed using the Discrete Cosine
Transformation technique with the aim of encrypting images without losing little or no value of its
initial pixel value. The encryption of the image is performed by converting the selected image into
a matrix using the image pixel values, then transforming the image pixel using the Discrete Cosine
Transformation Technique. The result of the encrypting process is image with altered pixel values
and a sequential representation of black, brown and white colors in a sequential order. The tools
used in the development of the system are: NetBeans IDE 8.1, Abstract Windows Toolkit and the
JAVA programming language. |
