“…Figure 6: LSB data steganography LSB2 works in the same manner as LSB method, but it uses the two least significant bits of the covering 4 bytes (for each character of the message) to do the replacement as shown in figure 7. LSB2 method doubles the capacity of data hiding, and it will equal the image size divided by 4, the extraction and the hiding times required for LSB2 method mostly less than those times required for LSB method [22,27]. LSB2 provides good values for quality parameters MSE, PSNR and CC and some times the quality of the stego_image using LSB2 method is better than the quality of the stego_image obtained by LSB method.…”

“…To enhance LSB2 method of steganography efficiency and to make it secure and capable to provide a high degree of secret message protection the following two points must be considered [22,27]. -Simplification of the operations used for data hiding and data extracting.…”

“… Availability of various equipment and devices that can be used to generate the digital image.  Ease of processing the color digital image, because it is represented by a three-dimensional matrix as shown in the figure 3, and accordingly, the operations of the digital image processors are nothing but the process of processing matrices [26][27][28][29][30]. And some of the circulating messages may be confidential or of a special personal nature that no third party has the right to view and understand, which requires providing the necessary protection for these messages to protect them from intruders or data thieves.…”

“…One of the most popular methods of data protection is data steganography [4][5][6][7][8]. Data steganography as shown in figure 5 means hiding the secret message in covering media (color image) before sending the message and extracting the message from the stego_image after receiving the image [22][23][24][25][26][27].…”

Data steganography is widely used in message protection from being read, and mostly used methods based on LSB and LSB2 methods are not enough secure. In this research paper a modified LSB2 method will be introduced. This method will use a complex complicated key to enhance the data protection degree. The key will be used to rearrange the message stream of bits before data hiding and before data extraction. The key will be sensitive to any minor changes giving a corrupted unreadable message when any change was done in the data extraction phase o data steganography phases. It will be shown that the proposed method very efficient comparing with other methods base on LSB or LSB2 methods. The proposed method will add an improvements to the process of steganography by reducing both the hiding and extracting times. It will be shown that the proposed modified LSB2 method will be used to treat any message short or long using any color image, the size of the used covering image will not affect the method efficiency, so we can use bigger covering images to enhance the quality of the stego image by optimizing the value of MSE and PSNR. The proposed method will be implemented and various analysis will be introduced to prove the improvements achieved by the proposed method.
