Securing Message Steganography by using Modified LSB Method

Message steganography is one of the popular methods used to protect secret message. In this research paper a modified LSB method of message steganography will be introduced. The introduced method will use a complicated private key to protect the message from being hacked, the key will provide an excellent key space capable to resist hacking attacks, it will contain 6 values with a double data type. The private key will be used to divide the covering image into segments and divide the secret message into partitions; each message partition will be hidden in one image segment. The hiding and extracting processes will be implemented in a patch way, by inserting the binary version of the message partition in burst way and extracting the binary version of the message partition also in burst way. The proposed method will keep the quality of the stego image as in LSB method. The efficiency of the proposed method will be closed to the efficiency of LSB method. The proposed method will be implemented and tested using various images and various covering images, the obtained results will be analyzed to prove the advantages provided by the proposed method.
