    Analysis and implementation of remote access computer communication
    (2015) Abdalrahman, Mouath
    Bu tezde uzaktan erişimli Sanal Özel ağ protokollerinin (PPTP,SSL, AND 2TP/IPsec) üç farklı tipi VMware ve GNS3 araçlarının kullanımı ile sanal olarak kurulmuştur. Buna ek olarak tüm protokollere benzer koşullar altında yapılan ölçüm testleri ile performansları test edilmniştir. Ayrıca, elde edilen bu sonuçlar, bir sonuca varılarak kıyaslama yapılabilmesi ve gelecek çalışmalara öneriler getirebilmesi için dikkatle çalışılmıştır.

    Comparison Between Embedding on Edges in Spatial and Frequency Domains
    (Ieee, 2015) ALjadir, Taha; MohyALdeen, Omar; Abdalrahman, Mouath
    Practically, digital watermarking is considered as an advanced field of investigating to avoid unauthorized copying and duplication. In this paper, a comparative analysis is conducted among embedding the watermark on the edges of a cover image in two domains, spatial and frequency domains. In this work, the Sobel edge detection algorithm is used to find edges and embed the watermark on the edge in each domain using DWT and DCT. Results demonstrated that the embedding process in frequency domain is more accurate and effective than it in spatial domain. Furthermore, the use of the four bands of frequency in DWT makes embedding on edge algorithm stronger and more robust with low MSE rates averagely
