Günümüzde, teknoloji ve internetin gelişerek yaygınlaşmasıyla, güvenli veri transferi için farklı yöntemler ve teknikler uygulanmaya başlanmıştır. Gelişen bu yöntemlerden biri de Steganografi’dir. Steganografi, iletilecek bilginin, istenmeyen kişiler tarafından fark edilmesini önlemek için farklı araçlara gizlenmesi sanatıdır. Taşıyıcı araçlarda gözle görülür değişiklik yapılmadan mesajın gizlenmesi hedeflenir. Bu çalışmada, önerilen kaotik yöntem ile video üzerinde veri gizlenmesi amaçlanmıştır. Videoda, veri gizlenecek çerçeveler ve pikseller belirli bir düzen olmadan kaotik bir yöntemle seçilerek, RGB değerlerinin en az anlamlı bitinin değiştirilmesi ile veri bir piksele 1 byte gizli bilgi olacak şekilde gizlemesi gerçekleştirilmiştir. Oluşturulan taşıyıcı videonun ve videonun ilk halinin görsel değerleri karşılaştırılarak gizlemenin başarısı PSNR, SNR, Entropi, SSIM, MSE yöntemleri ile ölçülmüştür.
