Carrier Image Rearrangement to Enhance the Security Level of LSB Method of Data Steganography

Least significant bit method is one of the most popular methods of data steganography, this method is very simple and provides good values for MSE and PSNR. LSB method is not secure enough and the embedded secret message can be easily hacked by any person with any programming experience. To enhance the security level of LSB and to protect the secret message from being hacked and addition stage is recommended. This stage adds a necessary protection without affecting the quality parameters and the efficiency of LSB. The protection process is based on using a complex private key, this key is generated by sender depending on the block size and the selected image size and kept in secret to be used by the receiver, the private key can be changed or updated any time, when the needs arise.
