Proposed LSB4 of Data Steganography

The process of hiding confidential data is one of the important processes used to protect this data from intruders or protect it from the penetration process. The most popular methods used in data steganography are LSB and LSB2 methods. These methods are efficient methods of data hiding, they provide a good stego media quality and good speed parameters. They are capable of hiding short and long secret messages. To increase the capacity and to decrease both the hiding and extraction times LSB4 method will be introduced and used. The proposed method will be implemented using various covering images and various in length secret messages, the obtained results will be analyzed to prove the quality and the speed of the proposed method. The obtained results of the proposed LSB4 method will be compared with the results of LSB method to show the enhancements provided by the proposed method. The proposed LSB4 method will be supplied by a security issues to protect the hidden message, the secret message will be protected by using a special private key to apply bits' substitution on the contents of characters' binary matrix.
