Information Security Group

Information Security Group deals with cryptography and steganography issues. Present work focuses on the steganography methods in sound.
The group works on various steganography methods used to realize secret communication.

The last obtained result is a new sound steganographic method consisting in combining Fourier transform and masking phenomenon. Fourier transform usage allows for obtaining good level of robustness to compression, filtration, format change and other popular sound transformations. Masking phenomenon usage allows additionally for obtaining good transparency of the hidden data.

The group works on improving the designed method by improving the used masking method and increasing steganographic capacity of the projected algorithm.

Dr. Grzegorz Koziel, Ph.D. (Eng.) is the head of the Information Security Group.
