GÖRÜNTÜ ŞİFRELEME İÇİN SCAN PATERNLERİNİ KULLANAN HİBRİT BİR YÖNTEM
Özet
Bu çalışmada, görüntü güvenliğinin sağlanması için kullanılabilecek hibrit bir görüntü şifreleme yöntemi önerilmiş ve bu yöntem bir uygulama ile anlatılmıştır. Normalde herhangi bir görüntüye gürültü ekleme işlemi de görüntü şifreleme olarak kabul edilebilmektedir. Ancak bu şekilde yapılan şifreleme basit filtreler tarafından geri dönüştürülebilir. Önerilen yöntem taşıyıcı görüntü ile şifreleme yapma mantığına dayanmaktadır. Şifreli görüntü elde etmek için, üretilen bir şifreleyici görüntü orijinal görüntüye eklenmektedir ve bir tarama yöntemi ile taranarak aşırı derecede bozulmuş şifreli bir görüntü elde edilebilmektedir. Elde edilen şifreli görüntünün, hibrit teknik ile daha fazla bozulmuş bir hale geldiği görülmüştür. Şifreli görüntüyü orijinal hale getirmek için ise ters işlem uygulanmaktadır.

A HYBRID METHOD USING THE SCAN PATERNS FOR IMAGE ENCRYPTION
Abstract
In this study, a hybrid image encryption method that can be used to provide image security is proposed and described in an application. Normally, adding noise to an image can also be considered as image encryption. However, encryption in this way can be recycled by simple filters. The proposed method is based on the ability to encrypt with the bearer image. To obtain an encrypted image, a cryptographic image is added to the original image, and a scrambled image that is extremely distorted can be obtained by scanning with a scan method. The resulting encrypted image has become more distorted by hybrid technique. In order to make the encrypted image the original, reverse process is applied.
Keywords: Encryption, Image Encryption, Zigzag Scan Patern.
