An Efficiency and Algorithm Detection for Stenography in Digital Symbols

In modern conditions; Steganography has become the digital strategy of hiding files in one form or other MEDIA like images, sound files or video files. Algorithms built-in digital information for color images based techniques steganography. This work presents a new method of steganography based on space domain to encode more information in the image, making small changes in their pixels. The results work obtained in this work that the new detection method of steganography based on new spatial coding additional information in the image, making small changes in their pixels based on the expansion of the range is designed for testing the proposed structure. This work study is to develop a new method to detect human faces, reflected in digital photography, with a high work rate and accuracy of detection.
