In this paper, a method for hiding cipher text in an image file is introduced . The
proposed method is to hide the cipher text message in the frequency domain of the image.
This method contained two phases: the first is embedding phase and the second is extraction
phase. In the embedding phase the image is transformed from time domain to frequency
domain using discrete wavelet decomposition technique (Haar). The text message encrypted
using RSA algorithm; then Least Significant Bit (LSB) algorithm used to hide secret message
in high frequency. The proposed method is tested in different images and showed success in
hiding information according to the Peak Signal to Noise Ratio (PSNR) measure of the the
original image .

The odalisque ( chambermaid) is every owned woman (possessed ). Her master has owned her either by buying her from the slavers who were travelling around in the lands to buy the odalisques and then selling them or they are captives of war.
Quran said "the women are under the control of men" this doesn't mean that the men were dictators in the affairs of women . But the men were ready to bear most of their burden or loads .
All aspects of life are controlled directly or indirectly by the church. The Crusades has the essential role in the weakness of feudalism because a lot of slaves escaped to participate in these wars and the Masters were unable to prevent them since the church blessed these Wars and the Participants
تميز الشعر الاندلسي بمجموعة من القيم الجمالية ، تبرز الجمال والقبيح والتراجيدي ، وعبر عن هذه القيم من خلال نظام بنائي جمالي مميز انسجم وطبيعة تلك القيم
والتراجيديا تتمثل بحالتين ، تتمثل الاولى بتجسيد الموت او البعد وماتبرزه من مآسٍ وحزن والم عند وقوع الحاله فيجسد الشاعر مشاعره واحاسيسه بالرثاء وذكرى الفقيد ويكثر من الشكوى ومايرافقها من حنين ودموع.
