Abstract:
The network security is very important
for data transmission on the internet and security
threat is very important challenges in any
communication system. This security of
information can be achieved by using encryption
and steganographic technique. In this paper, a
steganographic scattered LSB technique is
proposed by combining these two techniques.
This system is based on Pseudo Random Number
Generator to get cryptographic strength. In this
paper, BMP image file is used to hide the
encrypted message and RC4 encryption
algorithm is used for data encryption. To
generate the stego-image, BMP image file is
divided into number of blocks. As a consequence,
any opponent can’t know easily which data is
inserted in which block count. Therefore, we can
protect the privacy of our information.
Moreover, our technique intends for data
integrity and data confidentiality. This LSB
technique can be used for many applications in
computer science and other related fields.
