Abstract: In any form of communication, security is the most important aspect in today’s world. Many data security and data hiding algorithms have been developed in the past. In this project, named “A Framework For Digital Image Steganography”, we have designed a system that will allow an average user to securely transfer text messages by hiding them in a digital image file using the local characteristics within an image. This system is a combination of steganography and encryption algorithms, which provides a strong backbone for its security. The proposed system hides large volume of data within an image, and also limits the perceivable distortion that might occur in an image while processing it. This software has an advantage over other information security software because the hidden text is in the form of images, which are not obvious text information carriers. The project contains several challenges that make it interesting to develop. The main task is to research available steganography and encryption algorithms to pick the one that offer the best combination of strong encryption, usability and performance. The main advantage of this project is a simple, powerful and user-friendly GUI that plays a very large role in the success of the application.
