Abstract

Nowadays, because of developing technology, the necessity of protecting data in digital media (text, audio and image files) has occurred. As a consequence, encryption and steganographic techniques take the responsibility on protecting and hiding the data. While cryptography is about protecting the content of messages, steganography is about concealing their existence. Steganography is not an encryption technique. Nevertheless, it is a complementary technique and can be used with encryption techniques. In this study, a steganography application on 24-bit colored image in BMP (Windows Bitmap) format using LSB (Least Significant Bit) insertion method has been described.
