| Abstract | ||
| For the importance to achieving large communications security led to the need to hide information, and because the information does not appear either encrypted or unencrypted visible to others, it is considered a contributing factor to give protection and secure information. This, which attend to use different methods for this purpose as secured and hide information in different media. For a data hiding technique to be successful it needs to have confidentiality, integrity and availability Steganography allows for the concealment of files and messages within other files, such as pictures, audio and video. This allows for the easy transportation of sensitive data without prying eyes being able to tell a message is being transported. Image steganography has gotten more popular press in recent years than other kinds of steganography, possibly because of the flood of electronic image information available. This work has been built a security system to hide information in image file. The main algorithm concealment was used to hide in the least important (LSB) Least Significant Bit, transform the image of formula (RGB) to YCbCr image, and put the contents of the message in a one layer of image layers. For more security, the text message was encrypted using a cryptographic algorithm liner stream cipher, and then are included within the image files of BMP and JPEG format. | ||
