AB  - Bilgi Teknolojilerindekihızlı gelişim son zamanlarda İnternet üzerinden veri paylaşımınıkolaylaştırmıştır. Dijital verilerin izinsiz olarak kopyalanması veyadeğiştirilmesi telif hakkı koruma sorununu beraberinde getirmiştir. Kriptografihassas bilgileri güvenli bir şekilde paylaşmak için kullanılsa bile şifrelenmişbilgiler orijinal veri ile ilişkilendirilemediğinden telif hakkı korumasürecinde kullanılamazlar. Dijital haklar yönetiminde son zamanlarda sayısaldamgalama yöntemleri kullanılmaktadır. Özel hazırlanmış gizli bilgileri veyadamgayı sayısal ortama gizleme yöntemleri verilerin korunmasında ve sahiplikbilgilerinin belirlenmesinde ek güvenlik mekanizması sağlamaktadırlar. Çokluortam dosyalarındaki hak yönetimi için önerilen algoritmalar, veri tabanlarıüzerinde doğrudan uygulanamamaktadır. Veri tabanı damgalama için kullanılanyöntemlerden bazıları, ilişkide yer alan XML veri alanlarındanfaydalanmaktadır. Bu çalışmada XML alanlar üzerinde Homoglif Dönüşüm tabanlıyeni bir algoritma önerilmektedir. Birincil anahtar ve özüt fonksiyonu veri tabanındadamgalanacak satırların seçiminde kullanılmıştır. Sonuçlar, önerilen yönteminliteratürdeki diğer yöntemlerle karşılaştırıldığında yüksek damgalamakapasitesinde çeşitli ataklara karşı iyileştirilmiş sağlamlık elde ettiğinigöstermektedir.

N2  - Rapid developments inInformation Technologies have eased data sharing through the Internet recently.Copying or modification of digital data without permission and sharing byunauthorized users have brought copyright protection problem. Even thoughcryptography can be used to share sensitive information securely, it cannot beused to protect copyright since encrypted information cannot be associated withthe original. Digital watermarking methods are used lately in digital rightsmanagement. Methods to hide specially crafted secret information or watermarkinto digital media provide additional security mechanism in protecting the dataand determining the ownership information. Algorithms recommended for rightmanagement in multimedia files cannot be applied directly on databases. Somemethods used for watermarking databases take advantage of Extensible MarkupLanguage (XML) data fields attached. A new method based on HomoglyphTransformation in XML fields is proposed in this manuscript. Primary key andhash algorithm are used together in the selection of lines to be watermarked inthe database. Results indicate improved robustness against various attacks inhigh watermarking capacity by the proposed method compared to other methodsreported in the literature.
