In this paper, a method for hiding cipher text in an image file is introduced . The
proposed method is to hide the cipher text message in the frequency domain of the image.
This method contained two phases: the first is embedding phase and the second is extraction
phase. In the embedding phase the image is transformed from time domain to frequency
domain using discrete wavelet decomposition technique (Haar). The text message encrypted
using RSA algorithm; then Least Significant Bit (LSB) algorithm used to hide secret message
in high frequency. The proposed method is tested in different images and showed success in
hiding information according to the Peak Signal to Noise Ratio (PSNR) measure of the the
original image .

Virtual reality technology is the science of the embodiment of things and move spontaneously among non-real from one place to another with the full sense of the form, touch, sound, enables the user tried out and deal with it, like a real natural world and open up new worlds for human ambitious to let him overlooks the supposed world. Internet has become part of our daily lives, especially with the presence of mobile devices; that revolutionized the world of social networking. Access to information and build relationships change in the era of digital technology. The woman is not in isolation from this era; she found to herself a wide area for the production of ideas.

The research aims to explain the stage of recording Qur’anic readings in the blogs and writings of other sciences until it reached an independent, integrated science based on its principles, for which separate books were devoted to it, because of the necessity of highlighting that stage in which the science of Qur’anic readings overlapped with the blogs of other sciences. Because it relates to the gradual maturity of this science and its historical paths, the goal of the research is achieved by answering questions, the most important of which are: What are the science records in which Quranic readings were found, and what are the books that were unique to writing about this science. The researcher followed the inductive and desc
