Hiding information is an effective solution for the protection of copyright and confidentiality to allow a person to send the data in the middle of the cover image to a person without knowing any third party in this transmission, methods of delivering secret messages are very important. This research provides a way to hide data (which is a text file) after is encrypted adoption method (Keyword Mixed Transposition) to produce cipher text is included in Low–High coefficient wavelet transform and get a good quality image and the possibility of recovering fully embedded message and decoded without relying on the original image. Results have applied to the digital images to get inline images to the data with a high correlation coefficient when compared with the original images in addition to that they gave a few differences when calculating measurements(SNR, PSNR, MSE).
