VisKey — An implementation for hiding information

Steganography is the art of hiding information, which prevents the detection of hidden messages. It is derived from a Greek word technically meaning "Covered Writing". Comparing with cryptography, we can say that cryptography is a method where the message is not understood whereas steganography is a method where the message is not visible. Steganography can help us transcend the limitations of cryptography by making use of the limitations of the human auditory/visual system. The very fact is that steganography and cryptography should go hand in hand. While examining these data hiding techniques, important aspects such as degradation of the cover data must be kept to a minimum and hidden data must be made as immune as possible.
