Abstract
Gelişen teknoloji ile birlikte veri güvenliğinde yeni problemlerle karşılaşılmakta ve veri güvenliğini artırmak amacıyla, bu problemleri çözmeye yönelik girişimler yapılmaktadır.Yapılan araştırmalarda, veri güvenliğine yönelik problemler, matematiksel veya mantıksal önermelere dayanan veri şifreleme algoritmaları ile çözülmekte veya bir verinin farklı verilerin içerine mantıksal önermelere göre yerleştirilmesine dayanan steganografi algoritmaları geliştirilerek çözülmeye çalışılmaktadır. Bu çalışmalar sayesinde önemli veriler güvenlik altına alınabilmektedir. Steganografi tekniğine göre geliştirilen çoğu uygulamalar metin, ses ve resim üzerinde yoğunlaştığı görülmektedir. Bu çalışmada, gizlenmek istenen veri ilk olarak metin editöründen ASCII karakter formatında girilen ve gizlenmek istenen veri, ikili formata dönüştürülmektedir. İkinci aşamada, AVI formatındaki örtü videosunun kapasitesi oranında her frame’deki ilgili piksellerinin en önemsiz biti (LSB) kullanılarak, ikili formatındaki verinin ilgili bitiyle yerinin değiştirilmesi esasına dayanan bir steganografi uygulaması geliştirilmiştir

Abstract
A variety of new problems are encountered as the result of developing technology for data security. In order to ensure security of data, new improvements are made to solve these problems. According to the researchers in the literature, data security problems are solved by mathematical or logical propositions, based on the data encryption algorithms or by improving stenographical algorithms, which functions as placing the data into different data according to logical propositions. Many important data can be retrieved by the studies on data security processes. Most applications developed according to Steganography technique have been concentrated on the text, sound and image. In this study, firstly, ASCII formatted and data to be hided is entered from text editor and then converted to binary format. In the second step, a stenography application is developed that depends on the changing the placement of the least significant bit (LSB) in each frame’ in proportion of the cover video capacity in AVI format while converting the data to hide which is put in ASCII character format in text editor.
