Abstract
Günümüzde gelişen teknoloji ile birlikte dijital ortamdaki (metin, ses ve görüntü dosyaları) verilerin korunma ihtiyacı ortaya çıkmaktadır. Verilerin korunmasında ve gizlenmesinde şifreleme ve steganografi önemli rol oynamaktadırlar. Şifreleme mesajın içeriğinin korunması ile ilgilenirken steganografi mesajın varlığının gizlenmesi ile ilgilenmektedir. Dolayısıyla steganografi bir şifreleme yöntemi değil şifrelemeyi tamamlayıcı bir öğedir. Bu çalışmada BMP (Windows Bitmap) formatındaki 24-bit renkli resim dosyaları üzerinde en önemsiz bite ekleme yöntemi kullanılarak geliştirilen bir steganografi uygulaması anlatılmaktadır.

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.
