في بحثنا هذا تم استخدام ملف فيديو كوسط ناقل لإخفاء النص، و من خلال هذه الطريقة تم توفير الدقة في العرض و الموثوقية العالية في نقل البيانات. قمنا باختيار إطارات محددة من الفيديو و طبقنا التحويل الموجي المتقطع لإخفاء النص المشفر، مما يضمن لنا وصول الملف النصي بالشكل الصحيح و بسرية كبيرة.
In our research, we used a video file as a cover media to hide the text. This method provides a high quality in display and authenticity in data transfer. We chose specific frames from the video file and we apply DWT to hide the encryption text, which ensure that the text file is delivered correctly and secretly.

In this paper, a technique for hiding a message into digital images
(256 gray levels) is proposed. Some tests, on the proposed technique, are
done by applying the technique in hiding messages into some images. From
the recorded results, we can not
e that the proposed watermarking technique
introduces, in many cases, a reasonable way that can be used to hide secret
messages in the digital images.
A digital watermark is a signal that is embedded into digital data
(text, image, audio, video) in a manner that allows it to be extracted
later. This is done by embedding a pattern which contains the
author's data into the digital data.
In this r
esearch, we propose a comparison between three types of
transformations for embedding a watermark in the frequency
domain into digital images in an efficient and secure method that
allows the watermarking any type of digital images with good
perceptibility.
Epilepsy is a chronic neurological disorder that occurs in the brain،
and affects approximately 2% of people around the world، where
epilepsy patients face a lot of difficulties in everyday life due to the
occurrence of seizures. Electroencephalog
ram (EEG) is used in
the automated detection of epileptic seizures، which has
Characteristics of non-linear and non-stationary. In this research،
we conducted automated detection of the seizures from the scalp
EEG signals using a Level 5 Discrete Wavelet Transforms DWT to
analyze the signal and extracting statistical features (maximum،
minimum، mean، average ، standard deviation، the ratio between
the mean values) and Categorizing using artificial neural networks
ANN for classification. The suggested detection method has
89.85% detection accuracy with 90.60% sensitivity ، and 89.1%
specificity.

In this paper, we propose a new method to embed digital
watermarking in audio files, using Discrete Wavelet Transform
(DWT) and the way to extract the watermark data.
The method efficiency is measured using Peak Signal –to-Noise
Ratio (PSNR) , No
rmalized Correlation Coefficient (NC). The
advantage of our method is the robustness against several attacks
and compression.
