English Abstract
Steganography is an advanced data hiding technique that has been widely investigated in the recent years due to its efficiency in protecting the security of information exchanged over the internet.
Recently, several steganography methods have been introduced and developed to ensure the transmission of data in a secured way.
However, some of those methods, such as the Least Significant Bit (LSB) technique have certain limitations concerning the verification of attacks in the secret messages.
Therefore, this work introduces the development of Bi-LSB steganography method using the MATLAB program as a solution for the low security and capacity limitations of the traditional used LSB techniques.
The performance of the developed Bi-LSB technique is then compared with that of three traditional LSB techniques; 1-LSB, 2-LSB and 4-LSB based on using them in embedding the same secret messages in the same cover ones and then computing the Peak Signal to Noise Ratio (PSNR) values after adding a AWGN with different variance values to the stego file before extracting the secret message.
In addition, various methods of integrity are used.
A comparison is performed among the extracted messages and the original ones with the use of three integrity techniques; checksum, hash function and frequency techniques.
The obtained results illustrated that the presented Bi-LSB technique outperforms the traditional LSBs in terms of PSNR values.
It can be concluded that the increase in attack variance results in more degradation in the PSNR value of the secret message.
In addition, the hash function check method offers the best correlation percentage among the extracted messages and the original ones.
