Security and privacy are the most important issues in today's communication systems. In applications where the importance of your privacy is indispensable, the main aim is to send the text to desired target without being captured by the third persons. In this paper, we have proposed an algorithm to hide text, even if it saved in text file, in cover image file, the proposed algorithm has two stages, first, it encrypts the text using RSA algorithm, after that, it inserts the encrypted text in cover image file using The Least Significant Bit (LSB) technique. The proposed algorithm has been implemented and tested by using C#.net, our results have shown the efficiency of proposed work in hiding the text in an image and retrieve it.
