Abstract AR

ضمن هذا البحث نقدم عملية إخفاء نص داخل صورة رقمية رمادية.

خوارزمية النظام المقترح تعتمد على تحويلة المويجه الصحيح و تحويلة الجيب تمام.

و تعتمد الخوارزمية أيضا على ترميز النص قبل الإخفاء بطريقة الهوفمان و إخفاء النص داخل HL sub band.

و تم قياس درجة الضوضاء الصورة ذات العلامة المائية بمقياس PSNR.

و أيضا تم قياس مقدار النص المسترجع من الصورة ذات العلامة المائية بعد تنفيذ بعض طرق الهجوم على الصورة ذات العلامة المائية و كانت النتائج جيدة.

تم تنفيذ الخوارزمية باستخدام برنامج ماتلاب نسخة a 2010.

Abstract EN

In the current research work, a system of hiding a text in a digital grayscale image has been presented.

The algorithm system that had been used was adopted two transforms Integer Wavelet transform and Discrete Cosine transformed.

Huffman's code has been used to encoding the text before the embedding it in the cover image in the HL sub band.

Peak Signal to Noise Ratio (PSNR) was used to measure the effect of embedding text in the watermarked image; also correlation coefficient has been used to measure the ratio of the recovered text after applying an attack on the watermarked image and we get a good result.

The implementation of our proposed Algorithm is realized using MATLAB version 2010a.
