Hide encoded text within the image by using the third least significant bit

الملخص EN

This research includes building a system to hide the encoded text within the image file (cover) to produce material hidden file.The algorithm includes two major phases: 1 –The hide the text message encoded within the image.

At this stage is hiding the text message after encrypted inside the cover (file image) ,this phase consists of two main stages, the encryption process and hiding process.

2 -Message retrieval, the include the sequence of steps involved in the process of hiding and encoded, but reversing these steps.

Thehide algorithm proposed has been applied to more than image file and made a good recovery rate for data and text message without causing any noticeable distortion in the file cover and the size of the image increases the efficiency of hide and difficult , but cannot be anyone to distinguish the existence of any text within the image.
