The use of information over internet and our dependence on
the computing machines has drastically increased with the advancements in technology.
As a result, the storage and transmission of the ever increasing volumes of
data in an effective way has become a high priority issue. The very systems
which are boon to us are also being misused by many to cause harm. Thus, security
is a major issue as far as the information is concerned. Thus, it becomes the
responsibility of the parties involved in secret communication to arrange for
the necessary security, preventing the sniffing by rogue entities. Advancement
in digital communication technology along with internet makes data transfer
easy and vulnerable to interception and modification by sneakers. Cryptography
and steganography are ways of encrypting and hiding data. While Cryptography
hides the essence of the data under a cover, like an encrypted text or periodic
noises in a digital signal, steganography hides the fact of data itself. The
information is more secure when both these techniques are used together. That
is, even if the hidden information is found out, it will be encrypted. In this
paper, it is proposed to explore the cover generation method. It uses information
as data on covers like Image-cover, Circuit-cover Graph-cover, Chess-cover and
Questionnaire etc and does not produce noise. Thus, noiseless steganography
(noistega) is a fruitful option for data transmission in secured manner. |
