Providing a Better Protection During Exchange of Critical Data Based on Information Hiding Mechanism

Authors : V. Muneeswaran and S. Subramanian

Abstract: With the rapid advances in communication technology, most of the trusted data exchange happens electronically through various mediums such as Short Messaging Service (SMS), Multimedia Messaging Service (MMS) and electronic mail (e-mail) in the form of text, image, audio and video. For secure data exchange steganography can be employed rather than cryptography. Steganography is an ancient art of hiding confidential information in unsuspected objects like text, image, audio, video and Deoxyribonucleic Acid (DNA). It must not be confused with cryptography where it transforms the confidential data into unintelligible one. It does not give a meaning to a person who intercepts it. Digital technology gives us new ways to apply steganographic techniques including one of the most interesting practices of hiding information in digital images. An image can have more information than what researchers see with the Human Visual System (HVS) hence they can convey more than a 1000 words. The steganography technique that is provides a better protection to a data in transmission while compared to other techniques. It provides a high information hiding capacity and successfully controls the distortion of the stego image. This study presents a new way of providing confidential information in a secure manner.
