جرى في هذا البحث اقتراح طريقة لإخفاء رسائل نصية رقمية داخل بيانات لصور رقمية (بـ 256 مستوى رمادياً). و قد أجريت بعض الاختبارات، على الطريقة المقترحة، لإخفاء نصوص ضمن بيانات لصور رقمية، و لوحظ من خلال النتائج المسجلة أن الطريقة المقترحة في هذا البحث تقدم وسيلة مناسبة يمكن تبنيها بوصفها إحدى الوسائل المستخدمة في مجال إخفاء البيانات.
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 note that the proposed watermarking technique introduces, in many cases, a reasonable way that can be used to hide secret messages in the digital images.

This research will show a sturdy method to hide a text file into an
image using least significant bit algorithm and encrypting this text,
which allows to store English and Arabic texts with various sizes
and ensure that the text file is delivered correctly and secretly.
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.
Modern web content - news articles, blog posts, educational resources, marketing brochures - is predominantly multimodal. A notable trait is the inclusion of media such as images placed at meaningful locations within a textual narrative. Most often,
such images are accompanied by captions - either factual or stylistic (humorous, metaphorical, etc.) - making the narrative more engaging to the reader. While standalone image captioning has been extensively studied, captioning an image based on external knowledge such as its surrounding text remains under-explored. In this paper, we study this new task: given an image and an associated unstructured knowledge snippet, the goal is to generate a contextual caption for the image.
In this paper we propose a new steganography algorithm by a
random image segmentation to blocks of different size with several
steganographic algorithms to increasing the security of hiding
data. Both color and gray images have been used as cover files
for our method.
Not only poetry has been restricted to men, but also Arab
woman used to taste and write poetry since time immemorial, next
to her interest in prose and narratology comparable to all Arabs at
that Bedouin time—when they were still leading a simple life.
However, names of women have been revealed and broadly
circulated concering handling and criticizing poetry since antiquity.
