Steganography

1. Introduction Steganography conceals the fact that a message is being sent. It is a rule akin to covert channels, spread spectrum communication and invisible inks which adds other step in security. A message in ciphertext whitethorn arouse suspicion while an invisible message impart not. 1.1 Purpose of Paper This paper introduces steganography by explaining what it is, providing a brief news report with illustrations of some methods for implementing steganography, and comparing available softw ar providing steganographic services. Though the forms are many, the focus of the software evaluation in this paper is on the use of images in steganography. 1.2 Structure of Paper Section 2 bequeath define steganography, provide a brief history, and explain respective(a) methods of steganography. Section 3 leave behind review several software applications that provide steganographic services and mention the approaches taken. Section 4 will conclude with a brief discussion of the implications of stegaonographic technology. Section 5 will list the resources used in researching this topic and additive readings for those interested in more in-depth understanding of steganography. 2. Steganography 2.1 Definition The word steganography literally means covered writing as derived from Greek.

It includes a abundant array of methods of secret communications that conceal the very macrocosm of the message. Among these methods are invisible inks, microdots, character arrangement (other than the cryptographic methods of successor and substitution), digital signatures, covert channels and spread-spectrum communications. Steganography is the art of concealing the beingness of information within seemingly innocuous carriers. Steganography can be viewed as akin to cryptography. Both have been used throughout recorded history as means to protect information. At times these ii technologies seem to converge while the objectives of the two differ. Cryptographic techniques scramble messages so... If you want to get a full essay, order it on our website: Ordercustompaper.com
