DESIGN OF STEGANOGRAPHY APPLICATION ON IMAGE FILE USING C#

Abstract

The rapid development of digital media and its use covers various fields which are becoming a bigger challenge to create an information delivery system that ensures its security. One of them is with steganography. Steganography is a method for inserting pieces of confidential information in an object or other media. With steganography, information is hidden in such a way that its whereabouts are unknown, which is known as hidden information. This method is different from cryptographic methods, which encode existing information so that it cannot be read without knowing the key or password used, but remains known and not hidden. In this study, it was developed using Microsoft Visual C# to implement the Simple Least Significant Bit Substitution (Simple LSB Substitution) steganography method to hide information into a multimedia file. The multimedia file used is an image file as a medium for carrying confidential information.Keywords: steganography, multimedia, information insertion, simple LSB substitution
